Definitions
- the invention relates to a recyclable fabric for awnings made from a polyolefin yarn made of polypropylene fibers and melt binding fibers.
- Awning fabrics are currently preferably made from polyacrylonitrile (PAN) twists in 1: 1 plain weave with the highest possible weft and warp density.
- PAN polyacrylonitrile
- the fabrics In order to achieve a stiff handle required for awnings and water and oil repellent properties or sufficient water resistance, the fabrics must be provided with a chemical finish.
- Melamine-formaldehyde resins are used for the stiff handle and fluorocarbon resins are used for oil and water repellency.
- PAN fabrics A disadvantage of PAN fabrics is that no suitable way has been found to recycle PAN fabrics. For this reason, the not inconsiderable production waste that arises during the assembly of the awning fabrics and during edge trimming, as well as the used awnings, must be disposed of or incinerated.
- the present invention accordingly relates to a recyclable fabric which is characterized in that it consists of a polyolefin yarn made of polypropylene fibers and 1-20% by weight of a low-melting melt-binding fiber.
- the PP and melt binding fibers used are used in the form of staple fibers and contain customary auxiliaries and, above all, must have high UV stability and color fastness, in particular weather fastness.
- auxiliaries are, for example, UV stabilizers, thermal stabilizers and pigments.
- Suitable UV stabilizers are, for example, polymeric HALS ("hindering amine light stabilizers") or mixtures of different HALS stabilizers.
- Suitable pigments are organic and inorganic pigments which have the required high weather fastness and do not negatively influence the UV stability.
- the melt binding fibers have a lower melting point than the PP fibers.
- the melting point of the melt binding fibers is therefore preferably between 70 and 150 ° C.
- melt binding fibers are polyethylene (PE), copolyamide or copolyester fibers.
- bicomponent fibers can also be used.
- suitable bicomponent fibers are those which consist of a PP core and a PE jacket.
- PE fibers are preferably used.
- the PP fibers are spun with 1-20% by weight, preferably with 5-15% by weight, of melt-binding fibers as usual to form a yarn, for example on a three-cylinder ring spinning machine or on any other suitable spinning machine.
- PP fibers and melt binding fibers can be used with different fiber fineness (titers) can be used.
- PP fibers with a titer of between 1.5 and 5 dtex, particularly preferably between 1.7 and 3 dtex, and melt-binding fibers with a titer of ⁇ 5 dtex are preferably used. It is advantageous to use melt binding fibers with the lowest possible titer, since this can reduce the content of melt binding fibers.
- Yarn fineness can thus be achieved, which can also vary over a wide range. Yarns with a yarn count of Nm 20-60, particularly preferably of Nm 30-40, are preferably produced.
- the polyolefin yarn thus obtained is then optionally twisted as usual, for example by the double-wire method or another suitable method, and then processed into fabric as usual.
- the fabric After the usual washing of the fabric to remove the spinning and twisting preparation, the fabric is only provided with equipment for oil and water repellency. Fluorocarbon resins are preferably used for this. When heating to condense the fluorocarbon resin, the binding fiber melts and leads to the desired stiff grip after cooling and resolidification. The disadvantages of conventional stiff-grip equipment, such as writing effect, unpleasant smell and increased gel content of the regranulate, no longer occur.
- the fabrics thus obtained can preferably be used for the production of textile sun protection articles, in particular awnings, but also for boat covers, tarpaulins, camping furniture covers and the like.
- Example 1 A comparison of the recyclability of the fabric according to the invention (Example 1) with the recyclability of a PP fabric (Example 2) which, as usual, with a melamine-formaldehyde resin (Cassurit MT, Hoechst), a catalyst for crosslinking the resin (NKN, Hoechst) and a fluorocarbon resin (NUVA FH, Hoechst), shows that the fabric according to the invention can be re-used 100% after regranulation, for example for the production of injection molded articles or a 17 dtex staple fiber for carpets. However, the regranulate of a fabric according to Example 2 can only be used up to max. 30% new granules are added.
- Another advantage of the invention is that, apart from the mixing of the PP and the melt binding fibers, no additional process steps are necessary and no special plants are required.
- a fabric was made from the twine on a Sulzer projectile weaving machine in plain weave 1: 1 (30 warp threads / cm, 14.5 weft threads / cm).
- the fabric was washed to remove the spinning and twisting preparation with the addition of an anionic surfactant (Arkomon A conc. 2 g / l), dried and with the aqueous liquor of a fluorocarbon resin (NUVA FH 25 g / l, isopronanol 30 g / l ) padded (wet pick-up 55%). After drying at 110 ° C, condensation was carried out on a stenter at 145 ° C.
- an anionic surfactant Arkomon A conc. 2 g / l
- the finished fabric had the desired stiff grip without writing effect.
- the maximum tensile force according to DIN 53 857 was 294 daN in the warp and 167 daN in the weft direction.
- the water tightness according to DIN 53 886 resulted in 33 mbar.
- the fabric was regranulated on a recycling plant from EREMA.
- the regranulate could be used 100% for the production of a 17 dtex staple fiber on a Fleissner compact spinning machine.
- the mechanical properties of the fibers obtained were practically identical to those made from new granules.
- Example 2 (comparative example )
- a yarn of Nm 34 was spun from PP staple fibers of the type ASOTA V8803 (2.5 dtex, 60 mm staple length) on a three-cylinder ring spinning machine. The yarn was folded and twisted to a Nm 34/2-fold thread using the double-wire process (maximum tensile force 34.2 cN / tex, maximum tensile force elongation 19.8%).
- a fabric was made from the twine on a Sulzer projectile weaving machine in plain weave 1: 1 (30 warp threads / cm, 14.5 weft threads / cm).
- the fabric was washed with the addition of an anionic surfactant (Arkomon A conc. 2 g / l), dried and with the aqueous liquor of a fluorocarbon resin and a rigid handle resin (NUVA FH 25 g / l, Cassurit MT 100 g / l, catalyst NKN 12 g / l, isopropanol 30 g / l) padded (wet absorption 55%). After drying at 110 ° C, condensation was carried out on a stenter at 145 ° C.
- an anionic surfactant Arkomon A conc. 2 g / l
- the finished fabric showed an undesirable writing effect.
- the maximum tensile force according to DIN 53 857 was 289 daN in warp and 166 daN in weft direction, the maximum tensile elongation was 59% and 29%, respectively.
- the water resistance according to DIN 53 886 was 34 mbar.
- the fabric was regranulated on a recycling plant from EREMA.
- the regranulate had a fish-like odor and was able to produce a 17 dtex fiber on a Fleissner compact spinning system with a max. 30% mixed with new granules. With a higher proportion of regranulate, too many filament breaks occurred.
Abstract
Description
Die Erfindung betrifft ein aus einem Polyolefingarn aus Polypropylenfasern und Schmelzbindefasern hergestelltes recyclierbares Gewebe für Markisen.The invention relates to a recyclable fabric for awnings made from a polyolefin yarn made of polypropylene fibers and melt binding fibers.
Markisengewebe werden derzeit bevorzugt aus Polyacrylnitril (PAN)-Zwirnen in Leinwandbindung 1 : 1 mit größtmöglicher Schuß- und Kettendichte hergestellt. Zur Erzielung eines für Markisen geforderten steifen Griffs und wasser- und ölabweisender Eigenschaften bzw. einer ausreichenden Wasserdichtheit müssen die Gewebe mit einer chemischen Ausrüstung versehen werden. Für den steifen Griff werden dazu Melamin-Formaldehydharze und für die Öl- und Wasserabweisung Fluorkarbonharze eingesetzt.Awning fabrics are currently preferably made from polyacrylonitrile (PAN) twists in 1: 1 plain weave with the highest possible weft and warp density. In order to achieve a stiff handle required for awnings and water and oil repellent properties or sufficient water resistance, the fabrics must be provided with a chemical finish. Melamine-formaldehyde resins are used for the stiff handle and fluorocarbon resins are used for oil and water repellency.
Ein Nachteil der PAN-Gewebe ist, daß bisher kein geeigneter Weg gefunden werden konnte, PAN-Gewebe zu recyclieren. Aus diesem Grund müssen sowohl die nicht unbeträchtlichen Produktionsabfälle, die beim Konfektionieren der Markisentücher und beim Kantenschneiden entstehen, als auch die gebrauchten Markisen deponiert oder verbrannt werden.A disadvantage of PAN fabrics is that no suitable way has been found to recycle PAN fabrics. For this reason, the not inconsiderable production waste that arises during the assembly of the awning fabrics and during edge trimming, as well as the used awnings, must be disposed of or incinerated.
Es wurden daher Versuche unternommen, hoch-UV-stabile Gewebe, insbesonders Markisengewebe zu finden, die recyclierbar sind. Gewebe, die aus Polypropylen-(PP)-Feinfasern ohne chemische Ausrüstung hergestellt werden, sind zu 100 % recyclierbar und weisen eine ausgezeichnete UV-Stabilität, gleichwertig der von PAN-Markisengeweben, auf und besitzen darüberhinaus eine verbesserte Reiß- und Weiterreißfestigkeit und geringere bleibende Dehnung als PAN-Gewebe. Ohne Melamin-Formaldehydharz erreichen diese PP-Gewebe aber nicht den geforderten steifen Griff. Die Steifgriffausrüstung mit Melamin-Formaldehydharz führt jedoch zu einem verstärkten Schreibeffekt. Außerdem entstehen beim Recyclieren, etwa durch Aufschmelzen und Regranulieren, durch thermische Zersetzung der Melamin-Formaldehydharze geringe Mengen an Aminen, die dem Regranulat einen fischartigen Geruch verleihen. Trotz Schmelzfiltration verbleiben der unangenehme Geruch und, aufgrund des Melamin-Formaldehydharzes, klebrige Harzteilchen, sogenannte Gelpartikel, im Regranulat, sodaß nur etwa bis zu 30 % des Regranulates in Mischung mit Neuware wieder eingesetzt werden können.Attempts have therefore been made to find highly UV-stable fabrics, in particular awning fabrics, that are recyclable. Fabrics made from polypropylene (PP) fine fibers without chemical finishing are 100% recyclable and have excellent UV stability, equivalent to that of PAN awning fabrics, and also have improved tear and tear resistance and less permanent Stretch as PAN fabric. Without melamine-formaldehyde resin, these PP fabrics do not achieve the required stiff grip. However, the stiff handle finish with melamine-formaldehyde resin leads to an increased writing effect. In addition, small amounts of amines are formed during recycling, for example by melting and regranulation, by thermal decomposition of the melamine-formaldehyde resins, which give the regranulate a fish-like odor. Despite melt filtration, the unpleasant smell and, due to the melamine-formaldehyde resin, sticky resin particles, so-called gel particles, remain in the regranulate, so that only up to 30% of the regranulate can be reused in a mixture with new goods.
Aufgabe der vorliegenden Erfindung war es demnach die beschriebenen Nachteile der Steifgriffausrüstung zu vermeiden und ein gut recyclierbares Gewebe zu finden.
Unerwarteterweise konnte diese Aufgabe dadurch gelöst werden, daß anstelle eines reinen PP-Garns ein Mischgarn aus PP-Fasern und einer tieferschmelzenden Schmelzbindefaser zur Herstellung des Gewebes verwendet wird.It was therefore an object of the present invention to avoid the disadvantages of the rigid handle equipment described and to find a readily recyclable fabric.
Unexpectedly, this object was achieved in that instead of a pure PP yarn, a mixed yarn made of PP fibers and a low-melting melt-binding fiber is used to manufacture the fabric.
Gegenstand der vorliegenden Erfindung ist demnach ein recyclierbares Gewebe das dadurch gekennzeichnet ist, daß es aus einem Polyolefingarn aus Polypropylenfasern und 1 - 20 Gew.% einer tieferschmelzenden Schmelzbindefaser besteht.
Die verwendeten PP-und Schmelzbindefasern werden in Form von Stapelfasern eingesetzt und enthalten übliche Hilfsstoffe und müssen vor allem hohe UV-Stabilität und Farbechtheit, insbesonders Wetterechtheit aufweisen. Hilfsstoffe sind beispielsweise UV-Stabilisatoren, Thermostabilisatoren und Pigmente.
Geeignete UV-Stabilisatoren sind beispielsweise polymere HALS ("hinderd amine light stabilizers" ) oder Mischungen verschiedener HALS-Stabilisatoren.
Als Pigmente kommen organische und anorganische Pigmente in Frage, die die erforderliche hohe Wetterechtheit besitzen und die UV-Stabilität nicht negativ beeinflussen.
Die Schmelzbindefasern besitzen einen tieferen Schmelzpunkt als die PP-Fasern. Bevorzugt liegt der Schmelzpunkt der Schmelzbindefasern daher zwischen 70 und 150°C. Beispiele für Schmelzbindefasern sind Polyethylen (PE)-, Copolyamid- oder Copolyesterfasern. Es können auch sogenannte Bikomponentenfasern eingesetzt werden. Beispiele für geeignete Bikomponentenfasern sind solche, die aus einem PP-Kern und einem PE-Mantel bestehen. Bevorzugt werden jedoch PE-Fasern eingesetzt.
Die PP-Fasern werden mit 1 - 20 Gew.%, bevorzugt mit 5 - 15 Gew.% Schmelzbindefasern wie üblich zu einem Garn versponnen, etwa auf einer Dreizylinder-Ringspinn-Maschine oder auf jeder anderen geeigneten Spinnmaschine. Entsprechend der gewünschten Garnfeinheit können PP-Fasern und Schmelzbindefasern mit unterschiedlichen Faser-Feinheiten (Titern) verwendet werden. Bevorzugt werden PP-Fasern mit einem Titer zwischen 1,5 - 5 dtex, besonders bevorzugt zwischen 1,7 - 3 dtex, und Schmelzbindefasern mit einem Titer von ≦5 dtex eingesetzt. Dabei ist es von Vorteil, Schmelzbindefasern mit einem möglichst geringen Titer zu verwenden, da dadurch der Gehalt an Schmelzbindefasern reduziert werden kann. Es können somit Garnfeinheiten erzielt werden, die ebenfalls in einem großen Bereich variieren können. Bevorzugt werden Garne mit einer Garnfeinheit von Nm 20 - 60, besonders bevorzugt von Nm 30 - 40, hergestellt. Das so erhaltene Polyolefingarn wird dann gegebenenfalls wie üblich, etwa nach dem Doppel-Draht-Verfahren oder einem anderen geeigneten Verfahren, gezwirnt und anschließend wie üblich zu Gewebe verarbeitet.The present invention accordingly relates to a recyclable fabric which is characterized in that it consists of a polyolefin yarn made of polypropylene fibers and 1-20% by weight of a low-melting melt-binding fiber.
The PP and melt binding fibers used are used in the form of staple fibers and contain customary auxiliaries and, above all, must have high UV stability and color fastness, in particular weather fastness. Auxiliaries are, for example, UV stabilizers, thermal stabilizers and pigments.
Suitable UV stabilizers are, for example, polymeric HALS ("hindering amine light stabilizers") or mixtures of different HALS stabilizers.
Suitable pigments are organic and inorganic pigments which have the required high weather fastness and do not negatively influence the UV stability.
The melt binding fibers have a lower melting point than the PP fibers. The melting point of the melt binding fibers is therefore preferably between 70 and 150 ° C. Examples of melt binding fibers are polyethylene (PE), copolyamide or copolyester fibers. So-called bicomponent fibers can also be used. Examples of suitable bicomponent fibers are those which consist of a PP core and a PE jacket. However, PE fibers are preferably used.
The PP fibers are spun with 1-20% by weight, preferably with 5-15% by weight, of melt-binding fibers as usual to form a yarn, for example on a three-cylinder ring spinning machine or on any other suitable spinning machine. Depending on the desired yarn count, PP fibers and melt binding fibers can be used with different fiber fineness (titers) can be used. PP fibers with a titer of between 1.5 and 5 dtex, particularly preferably between 1.7 and 3 dtex, and melt-binding fibers with a titer of ≦ 5 dtex are preferably used. It is advantageous to use melt binding fibers with the lowest possible titer, since this can reduce the content of melt binding fibers. Yarn fineness can thus be achieved, which can also vary over a wide range. Yarns with a yarn count of Nm 20-60, particularly preferably of Nm 30-40, are preferably produced. The polyolefin yarn thus obtained is then optionally twisted as usual, for example by the double-wire method or another suitable method, and then processed into fabric as usual.
Nach dem üblichen Waschen des Gewebes zur Entfernung der Spinn- und Zwirnpräparation wird das Gewebe nur noch mit einer Ausrüstung zur Öl- und Wasserabweisung versehen. Bevorzugt werden dafür Fluorkarbonharze eingesetzt. Beim zum Kondensieren des Fluorkarbonharzes notwendigen Erhitzen schmilzt die Bindefaser und führt nach dem Abkühlen und Wiedererstarren zu dem gewünschten Steifgriff. Die bisher aufgetretenen Nachteile der herkömmlichen Steifgriffausrüstung, wie Schreibeffekt, unangenehmer Geruch und erhöhter Gelanteil des Regranulates treten nicht mehr auf.
Die so erhaltenen Gewebe können bevorzugt zur Herstellung von textilen Sonnenschutzartikeln, insbesondere von Markisen, aber auch für Bootsabdeckungen, Zeltplanen, Campingmöbelabdeckungen und ähnliches verwendet werden.After the usual washing of the fabric to remove the spinning and twisting preparation, the fabric is only provided with equipment for oil and water repellency. Fluorocarbon resins are preferably used for this. When heating to condense the fluorocarbon resin, the binding fiber melts and leads to the desired stiff grip after cooling and resolidification. The disadvantages of conventional stiff-grip equipment, such as writing effect, unpleasant smell and increased gel content of the regranulate, no longer occur.
The fabrics thus obtained can preferably be used for the production of textile sun protection articles, in particular awnings, but also for boat covers, tarpaulins, camping furniture covers and the like.
Ein Vergleich der Recyclierbarkeit des erfindungsgemäßen Gewebes (Beispiel 1) mit der Recyclierbarkeit eines PP-Gewebes (Beispiel 2), das wie bisher üblich mit einem Melamin-Formaldehydharz (Cassurit MT, Fa. Hoechst), einem Katalysator zum Vernetzen des Harzes (NKN, Fa. Hoechst) und einem Fluorkarbonharz (NUVA FH , Fa. Hoechst) ausgerüstet wurde, zeigt, daß das erfindungsgemäße Gewebe nach Regranulierung zu 100 %, etwa zur Herstellung für Spritzgußartikel oder einer 17 dtex Stapelfaser für Teppiche, wiedereingesetzt werden kann. Das Regranulat eines Gewebe gemäß Beispiel 2 kann jedoch bei der Faserproduktion nur bis zu max. 30 % neuem Granulat zugesetzt werden.A comparison of the recyclability of the fabric according to the invention (Example 1) with the recyclability of a PP fabric (Example 2) which, as usual, with a melamine-formaldehyde resin (Cassurit MT, Hoechst), a catalyst for crosslinking the resin (NKN, Hoechst) and a fluorocarbon resin (NUVA FH, Hoechst), shows that the fabric according to the invention can be re-used 100% after regranulation, for example for the production of injection molded articles or a 17 dtex staple fiber for carpets. However, the regranulate of a fabric according to Example 2 can only be used up to max. 30% new granules are added.
Ein weiterer Vorteil der Erfindung besteht darin, daß außer dem Mischen der PP- und der Schmelzbindefasern keine zusätzlichen Verfahrensschritte notwendig sind und keine speziellen Anlagen benötigt werden.Another advantage of the invention is that, apart from the mixing of the PP and the melt binding fibers, no additional process steps are necessary and no special plants are required.
Eine Mischung von PP-Stapelfasern der Type ASOTA V8803 2,5 dtex, 60 mm Schnittlänge (hoch-UV-stabil, spinngefärbt, Höchstzugkraft 4.1 cN/dtex, Höchstzugkraft-Dehnung 30 %) und 13 % einer PE-Bindefaser der Type ASOTA V4603 3,3 dtex, 40 mm Stapellänge (hoch-UV-stabil, Schmelzpunkt 128°C) wurde in bekannter Weise auf einer Dreizylinder-Ringspinn-Maschine zu einem Garn der Nm 34 ausgesponnen. Dieses Garn wurde gefacht und nach dem Doppel-Draht-Verfahren zu einem Zwirn Nm 34/2-fach verzwirnt (Höchstzugkraft 33,4 cN/tex, Höchstzugkraft-Dehnung 20,1 %).A mixture of PP staple fibers of the type ASOTA V8803 2.5 dtex, 60 mm cutting length (highly UV-stable, spun-dyed, maximum tensile strength 4.1 cN / dtex, maximum tensile strength elongation 30%) and 13% of a PE binding fiber of the type ASOTA V4603 3.3 dtex, 40 mm stack length (highly UV-stable, melting point 128 ° C.) was spun out in a known manner on a three-cylinder ring spinning machine to a yarn of Nm 34. This yarn was folded and twisted to a Nm 34/2-fold thread using the double-wire process (maximum tensile strength 33.4 cN / tex, maximum tensile strength elongation 20.1%).
Aus dem Zwirn wurde auf einer Sulzer Projektilwebmaschine in Leinwandbindung 1:1 ein Gewebe hergestellt (30 Kettfäden/cm, 14,5 Schußfäden/cm).A fabric was made from the twine on a Sulzer projectile weaving machine in plain weave 1: 1 (30 warp threads / cm, 14.5 weft threads / cm).
Das Gewebe wurde zur Entfernung der Spinn- und Zwirn-Präparation unter Zusatz eines anionischen Tensids (Arkomon A konz. 2 g/l) gewaschen, getrocknet und mit der wässrigen Flotte eines Fluorkarbonharzes (NUVA FH 25 g/l, Isopronanol 30 g/l) foulardiert (Naßaufnahme 55 %). Nach dem Trocknen bei 110°C wurde auf einem Spannrahmen bei 145°C kondensiert.The fabric was washed to remove the spinning and twisting preparation with the addition of an anionic surfactant (Arkomon A conc. 2 g / l), dried and with the aqueous liquor of a fluorocarbon resin (NUVA FH 25 g / l, isopronanol 30 g / l ) padded (wet pick-up 55%). After drying at 110 ° C, condensation was carried out on a stenter at 145 ° C.
Das fertig ausgerüstete Gewebe wies den gewünschten steifen Griff ohne Schreibeffekt auf. Die Höchstzugkraft nach DIN 53 857 betrug 294 daN in Kett- und 167 daN in Schußrichtung. Die Höchstkraft-Dehnung 58 bzw 29 %. Die Wasserdichtheit nach DIN 53 886 ergab 33 mbar.The finished fabric had the desired stiff grip without writing effect. The maximum tensile force according to DIN 53 857 was 294 daN in the warp and 167 daN in the weft direction. The maximum force elongation 58 or 29%. The water tightness according to DIN 53 886 resulted in 33 mbar.
Das Gewebe wurde auf einer Recyclinganlage der Fa. EREMA regranuliert. Das Regranulat konnte zu 100 % zur Herstellung einer 17 dtex Stapelfaser auf einer Fleissner-Kompaktspinnanlage eingesetzt werden. Die mechanischen Eigenschaften der erhaltenen Fasern waren praktisch identisch mit den aus neuem Granulat hergestellten.The fabric was regranulated on a recycling plant from EREMA. The regranulate could be used 100% for the production of a 17 dtex staple fiber on a Fleissner compact spinning machine. The mechanical properties of the fibers obtained were practically identical to those made from new granules.
Aus PP-Stapelfasern der Type ASOTA V8803 (2,5 dtex, 60 mm Stapellänge) wurde auf einer Dreizylinder-Ringspinnmaschine ein Garn der Nm 34 ausgesponnen. Das Garn wurde gefacht und nach dem Doppel-Draht-Verfahren zu einem Zwirn Nm 34/2-fach verzwirnt (Höchstzugkraft 34,2 cN/tex, Höchstzugkraft-Dehnung 19,8 %).A yarn of Nm 34 was spun from PP staple fibers of the type ASOTA V8803 (2.5 dtex, 60 mm staple length) on a three-cylinder ring spinning machine. The yarn was folded and twisted to a Nm 34/2-fold thread using the double-wire process (maximum tensile force 34.2 cN / tex, maximum tensile force elongation 19.8%).
Aus dem Zwirn wurde auf einer Sulzer Projektilwebmaschine in Leinwandbindung 1:1 ein Gewebe hergestellt (30 Kettfäden/cm, 14,5 Schußfäden/cm).A fabric was made from the twine on a Sulzer projectile weaving machine in plain weave 1: 1 (30 warp threads / cm, 14.5 weft threads / cm).
Das Gewebe wurde unter Zusatz eines anionischen Tensids (Arkomon A konz. 2 g/l) gewaschen, getrocknet und mit der wässrigen Flotte eines Fluorkarbonharzes und eines Steifgriffharzes (NUVA FH 25 g/l, Cassurit MT 100 g/l, Katalysator NKN 12 g/l, Isopropanol 30 g/l) fouladiert (Naßaufnahme 55 %). Nach dem Trocknen bei 110°C wurde auf einem Spannrahmen bei 145°C kondensiert.The fabric was washed with the addition of an anionic surfactant (Arkomon A conc. 2 g / l), dried and with the aqueous liquor of a fluorocarbon resin and a rigid handle resin (NUVA FH 25 g / l, Cassurit MT 100 g / l, catalyst NKN 12 g / l, isopropanol 30 g / l) padded (wet absorption 55%). After drying at 110 ° C, condensation was carried out on a stenter at 145 ° C.
Das fertig ausgerüstete Gewebe zeigte einen unerwünschten Schreibeffekt. Die Höchstzugkraft nach DIN 53 857 betrug 289 daN in Kett- und 166 daN in Schußrichtung, die Höchstzugkraft-Dehnung 59 % bzw. 29 %. Die Wasserdichtheit nach DIN 53 886 war 34 mbar.The finished fabric showed an undesirable writing effect. The maximum tensile force according to DIN 53 857 was 289 daN in warp and 166 daN in weft direction, the maximum tensile elongation was 59% and 29%, respectively. The water resistance according to DIN 53 886 was 34 mbar.
Das Gewebe wurde auf einer Recyclinganlage der Fa. EREMA regranuliert. Das Regranulat wies einen fischartigen Geruch auf und konnte bei der Faserherstellung einer 17 dtex-Faser auf einer Fleissner-Kompaktspinnanlage zu max. 30 % mit neuem Granulat vermischt, eingesetzt werden. Bei höherem Regranulat-Anteil traten zu viele Filamentbrüche auf.The fabric was regranulated on a recycling plant from EREMA. The regranulate had a fish-like odor and was able to produce a 17 dtex fiber on a Fleissner compact spinning system with a max. 30% mixed with new granules. With a higher proportion of regranulate, too many filament breaks occurred.
