Abstract
Abstract A tufting carpet is described which comprises a tufting base, a pile material and a carpet back and essentially consists exclusively of polyamide 6. Through the use of a chemically uniform material in all components of the tufting carpet, the latter can be recycled as a whole for recovery of the monomeric starting material without the need for separation into the individual components, which has hitherto hampered the recycling of tufting carpets and led to major waste disposal problems.
Description
2 ~ 8 3 The invention relates to a tufting carpet and to its use as a floor and wall covering.
Carpets are tufted, woven, knotted and needled from manmade ibres, wool, haircord, silk and cotton. Tufting is the dominant production technique for factory-manufactured carpets, the use of manmade fibres and in particular polyamide (mainly polyamide 6.6) filament yarns and staple fibre yarns predominating. The factory-finished tufting carpet, which can be used as both a floor covering and a wall covering, offers not only comfort buk also considerable advantages in terms of insulation, and thereby aids the heat balance in buildings.
The tufting carpet structures usual today predominantly consist of three components, namely the tufting base, the 1~ pile material and the carpet back. Various materials, which differ basically from one another in chemical terms and cannot be regenerated with one another, e.g. polypropylene, polyamide, polyurethane, polyvinyl chloride and ~ute, are used for these components. Combinations of polypropylene as base woven fabri'c, polyamide as pile material and polyurethane as bacX coating predominate.
The tufting base is a woven fabric which predominantly com-prises polypropylene or a spun non-woven made from polyester or polypropylene. Jute woven fabrics are used more rarely.
The pile material consists predominankly of skaple ibres made from polyamide, secondarily spun and then subsequently tufted, or of polyamides which have been extruded in a single- or multi-step process to produce a continuous filament yarn, stretched and texturized (BCF yarns = bulked continuous ~ilament).
206~683 The carpet back performs several functions. A rubber or SB
la~ex pre-coa~ing is added to the tufted carpet to secure the -tufting loops. In the case of tuIting carpets ~or objects, a second back predominantIy comprising polyester woven fabric is frequently glued on and the carpet laid thus. For use in the residential sector, partly ~illed oams based on latex or polyurethane are usually added to increase comort.
The ~ufting carpets structured in the manner described pose a major refuse~ or waste-disposal problem once their use is finished, as they occur in large quantities (large volume and large weight) and practically disintegrate not at all, or only very slowly. Separation into the individual components and re-use of these components is also extremely di~ficult or virtually impossible and has thus been disregarded to date already on purely economic grounds. In view o~ the e~er-increasing waste-disposal problems, there is thus a pressing ne~d for tufting carpets which can be easily disposed of or re-utilized a~ter use.
Therefore the invention provides a tufting carpet which can be easily disposed of or is preferably reutilizable (recyclable) after use.
According to one aspect of the invention, a tufting carpet comprises a tufting base, a pile material and a carpet back and essentially consists exclusively of polyamide 6.
According to another aspect of the invention, a tufting carpet comprises a tufting base, a pile material, and , a carpet back, wherein the base, pile material and carpet back are all made substantially of polyamide 6.
A ~urther subjec~ o~ the invention is the use o~ the carpet according to the i.nventLon as a floor and wall covering.
Preferred embodiments and advantages will become apparen~
from the following detailed description of preferred embodiments o~ the invention.
It was surprisingly found that the manufacture of tufting carpets from essentially a single chemically uniform material (apart from usual auxiliaries such as dyestuffs, antistatic agents etc.) is possible if the material for the various components is carefully selected with regard to the necessary properties. Through the use of a chemically uniform material in all components of the tufting carpet it is no longer necessary, when working-up and re-utilizing used carpet, to separate the components and their consti$uents from one another. Rather, the carpet can be recycled as a whole to xecover the monomeric starting material, since polyamide 6 can be recycled into the monomeric starting product caprolactam by simple depolymerization.
In addition the invention provides the advantage that the use of a chemically uniform material in all components of the tufting carpet provides equal dyeability of the pile and base and increased light stability in comparison to the conventional use of pol~propylene as tufting base.
Furthermore, the tufting carpet according to the invention provides higher elasticity, allows the application o higher dying and ~inishing temperatures, and thus produces an overall positive economic result.
. "
2~683 rrhe tufting base of the tufting carpet according to the invention comprises a woven fabric, k~itted fabric, non-woven or a stretched film made from polyamide 6. If a textile fabric manufactured by means o~ warp-~nitting -warp-knitted fabxic - is used, the knitwear should mainly be produced with the following lay:
Guide bar 1 ~velvet) 102-454 Guide bar 2 (pillar) 100-011 Stitches/cm 20 Pitch (numbex of needles) E 28 Knitwear in this version gives a stable product web without rolling selvedges and is firm in itself given adequate longitudinal and lateral extension. Because of the high racking in guide bar 1, the lay chosen prevents severance of the total structure in the event of any damage to filaments from the tufting needles.
The knitwear leads to an extensible tufting carpet which can be stabili~ed by the following back securing but still has the necessary extensibility of 3 to 7% for tensioning. The knitwear also displays high displacement strength, so that problems, e.g. tearing of the carpet at the needle strip caused by low displacement strength, are avoided.
The yarns used for the knitwear, predominantly filament yarns, lie in the denier range from 20 dtex to 200 dtex (1 dtex = 0,9 den).Yarns with a denier of 44 dtex or 67 dtex have proved particularly suitable. The filament yarns display a shrinkage of ca. 14%, which can be triggered by heating (fixing). If the pile is tufted on before the fixing, triggering the shrinkage results in a compression of the surface and thus an increase in the qual;ty of the tufting carpet. On the other hand, one can tuft to 2 ~ 8 3 advantage on a coarser machine pitch and use the triggexed shrinkage to achieve a product surface as from a tufting machine with a finer pitch. For example, a tufting product ~1/10' pitch, 8 mm pile, 45 stitches/cm) shrinks, using the warp-knitted product described above as carrier material, by 25~ from 1270 g/m2 to 1600 g/m2. If such shrinkage effects are not wanted, totally fixed and thus stabilized knitwear of the same structure can be used as tuting base.
With a woven product as tufting base, plain weave is preferred in order to achieve uniform stability in warp and weft. The thread density in warp and weft depends on the yarn thickness used. Chiefly suitable are yarns in the fineness range from 200 to 4000 dtex. Typical thread densities for a yarn thickness of 300 dtex are 8 to 14 threads/cm in the warp, and 5 to 10 threads/cm in the weft for a yarn thickness of 1100 dtex. The displacement strength and diagonal stability of the coarse woven fabrics can be impro~ed ~y additionally applying a layer of a non-woven. In the case of the woven product, extensibility is at a low level because of the marked power absorption caused by the weave, so that the lower extension range of 3~ must be chosen for tensioning.
, . , However, carpets with greater extension can be produced here as well by means of texturized yarns, i.e. polyamide yarns with higher elasticity, and can be finished to measure to meet the needs of the use.
A non-wo~en as carpet base exhibits a uniform strength in all directions with an extensibility which can be adiusted through the securing, but its strength is less than that of other base products. Particularly suitable are non-wovens with a weight of 90 to 200 glm2 and preferably 110 to 150 g/m2 and a strength in longitudinal direction of 130 to 170 2 ~ 3 N/5 cm and preferably 140 to 160 N/5 cm and a strength in transverse direction 100 to 150 N/5 cm and preferably 110 to 140 N/5 cm.
Yarn spun secondarily in the usual way from staple fibres, continuous stretch-tsxturized filament yarn or another yarn manufactured in whatever way exclusively ~rom polyamide 6 is used as pile or tuft material. The yarn, which lies chie~ly in the denier range from 800 dtex to 40~0 dtex, can be used texturized normally or additionally fixed or twisted and fixed.
The pile tufting loops are secured by gluing with a polyamide film or with polyamide melt adhesive powder or a partially solvated polyamide melt.
In order to secure the tufting loops, the polyamide film or polyamide powder must be heated until it flows or a partially solvated polyami~e melt applied while liquid in order to secure the tufting loops satisfactorily. A
copolyamide characterized by a reduced melting point is used to advantage, but the highest possible proportion of polyamide 6 is chosen, especially copolyamides with a polyamide 6 content of at least 80 wt.-~ and preferably at least 90 wt.-%. ~he auxiliary component introduced to the least extent is of subordinate significance relative to the total weight of the material used and therefore poses no problems for recycling through depolymerization and the associate~ attemp~ to recover the starting component, caprolactam. Copol~yamides suitable for this purpose are standard commercial melt adhesives a~ailable both in film form and in powder form.
The degree of securing can be controlled through both the type of copolymer and the thickness of the ~ilm or the 2 ~ 8 3 amount of the powder in order to reflect application ~nd use. Deposits of 30 to 90 g/m2 and pref2rably 40 to 70 g/m2 are typical. At the same time, the extensibili~y of the carpet for tensioning, especially when using knitwear as carpet base, is pre-set by the degree oE securing.
When the tufting loops are being secured, a textile surface made from polyamide 6, e.g. a woven product, a non-woven or knitwear, can be simultaneou~ly applied as a second back for additional stabilization of the carpet. The carpet ~tructure according to the inve~tion is laid with or without a separate insulation layer without gluing by tensioning over needle strips. ~he insulation layer itself can then be taken up again after use has ended and re-utilized separately. In this way the laid carpet remains recyclable.
Practice of the invention will be become further apparent from the following non-limiting examples.
