Abstract
The invention provides a water-absorbing melt-blow non-woven fabric and a preparation method for the same. The water-absorbing melt-blow non-woven fabric is in a skin-covering-core type side-by-side composite structure. A first skin-covering part is formed by 30% to 70% of resin composite; the resin composite is formed by sulphone hydrophilic resin and other resin; other resin is formed by either polyolefin resin, polyester resin or polybutylene terephthalate or more than one; a second core part is formed by 70% to 30% of other resin or polyamide resin. The non-woven fabric is in the skin-covering-core type side-by-side composite structure; the skin-covering material is made from hydrophilic material, thereby improving non-woven fabric water-absorbing quality and maintaining ventilating property; and the non-woven fabric can be repeatedly used.
Description
Technical field
The invention belongs to nonwoven cloth material field, particularly one water suction melt spraying non-woven fabrics and preparation method thereof.
Background technology
Existing high-hydroscopicity melt spraying non-woven fabrics the fiber after spinning sprays or absorptive substance that the mode of impregnation is adsorbed and possess water imbibition.Be used for disposable products.Concrete mode is: use polyolefin-based resins, be supplied to the nozzle of several rows of row by multiple hole after melting, in nozzle bore, during molten polymer continuous spinning, in the slit of nozzle bore both sides, high velocity jet contains the solution of hydroaropic substance, obtained fibre diameter is 3-10 micron.
In Korea S, the liquid that molten polymer is formed as polymer is assigned to the fiber spinning apparatus transformed to carry.Liquid finishing agent is used in the surface of the molten polymer liquid in device for spinning.The absorptive material that possesses made may be used for infant article (as diaper), or feminine care products.
Comprise exterior layer and the interior layer of more than one deck at the nonwoven fabric of Korea S's multi-ply construction, wherein the acrylic resin of 40-90% defines interior layer, and the polyvinyl resin of 10-60% defined outside once, and the weight of spray fusing nonwoven fabric is 0.3-2gsm.This nonwoven fabric not only has cut-out effect, and soft-touch, is suitable for amenities.
But the outstanding nonwoven fabric initial stage absorption speed of water imbibition is higher, also gas permeability is to a certain degree possessed, but owing to being the mode process such as the surface injection of fiber process or impregnation, so can only disposable products be used for, and the problem that under there will be hot conditions, performance reduces and surperficial xanthochromia and the larger problem of viscosity.So nonwoven fabric technology still needs to improve.
Summary of the invention
The object of this invention is to provide a kind of there is remarkable water absorbing properties while washing after water imbibition constant class recycling water suction spray fusing nonwoven fabric.
For realizing above object, technical scheme of the present invention is:
A kind of water suction melt spraying non-woven fabrics, for suitcase core pattern shape composite construction side by side, first foreskin part is the resin compound of 30-70%, resin compound comprises sulfone system hydrophilic resin and other resins, other resins be vistanex, mylar, polybutylene terephthalate (PBT) any one and more than; Second core is other resins or the polyamide of 70%-30%.
Described sulfone system hydrophilic resin accounts for the 3-15% of Part I and Part II gross weight.
Described polyamide is intrinsic viscosity IV0.455, and melting density is 1.11g/cm
3resin.
Described vistanex is acrylic resin.
The preparation method of composite spinning melt spraying non-woven fabrics is: 1) process raw material, make its moisture at below 150ppm, 2) then heating and melting, 3) by two squeezers, the polymer of melting is sprayed through nozzle, 4) cooling.
The cooling-air of 5-20 DEG C is adopted to force cooling in cooling step.
Described nozzle is core-skin type nozzle, and density is 20-100hole/inch.
Obtained non-woven weight is 10-200g/m2.
Manufactured water suction melt spraying non-woven fabrics, for water treatment film, amenities and industrial goods.
Water imbibition melt spraying non-woven fabrics of the present invention uses 2 kinds of different different raw materials to mix in feedway, wherein drop into sulfone system hydroaropic substance in raw material feed device on one side, polymer melting compressed by two squeezers is after by gear pump, each distributes, the resin spued from the distribution plate of nozzle is with the extension of the air molten polymer of High Temperature High Pressure, cooling limit, superfineization back allows the fiber pad of superfineization roll on a moving belt, the melt spraying non-woven fabrics of water absorbing properties is now had to be subject to melt temperature, air themperature, air pressure, chilling temperature and from nozzle to the impact of conveyer belt distance.But what have the greatest impact is the constituent ratio of polymer.The identical lower air pressure increase of other conditions can cause fibre crystallinity to increase and intensity increases, thus improves the intensity of fiber.And the higher injection index of water absorbing component content can increase.
The nozzle of melt-blown use is 25-100hole/inch, and polymer each polymer before weaving silk of melting flows at each distribution plate, defines the fusion spray cloth of core-skin type or type side by side before nozzle spinning.The fibre diameter of fusion spray cloth of the present invention is 1-10 micron, and fibre diameter is less, and the fiber of unit are is more, and intensity is higher.
Beneficial effect:
Nonwoven fabric of the present invention adopts core-skin type or side-by-side-type structure, wherein employs hydroaropic substance in skin material, can also improve the water imbibition of nonwoven fabric and keep its gas permeability, and can reuse.
