Abstract
The present invention relates to a method for making composite laminated surfacing materials for all-weather clothes, which comprises the following steps that firstly, coiled fabrics of a surface layer are installed on a coating machine so that the fabrics of the surface layer continuously pass through the coating machine; the speed of weaving is 5 to 50 meters / second; then, the coiled micropore films are installed on a film withdrawing machine arranged in front of a composition position, and the films are withdrawn at the speed of 5 to 50 meters / second. The fabrics of the surface layer, which are provided with adhesive agents, enter a composite device in a composite position after the fabrics of the surface layer are laminated with the micropore films at the equal speed; the fabrics and the micropore films are compounded into a whole body by laminating and processing of pyretic fumigation.
Description
Technical field
The present invention relates to a kind of production method that is used for the laminated shell fabric of all-weather clothes, this method be will have the microporous membrane of Waterproof Breathable effect through after the specially treated, carry out the compound garment material of making that has waterproof, uses under multi-functional, all weather conditions such as wet, windproof, warming thoroughly of lamination by adhesive and fabric.
Background technology
Twenty or thirty scribbled polyvinyl chloride, polyurethane, neoprene latex and various elastomeric top-weight fabric and is obtaining general application aspect the clothes of bad weather dress in year in the past.Although the clothes that these fabrics are made have been given superior rain proofness, and a spot of windproof property arranged, but can long-pending there be condensed water on the surface and uncomfortable feeling is arranged within it, this kind fabric moisture that human body can not be distributed constantly exhales in fact, promptly there is not poisture-penetrability, in the vigorous exercises such as outdoor sports such as march, operation, mountain-climbing, when wearing this class waterproof garment, because a large amount of sweat can't be discharged with vapor form, form condensed water at inner, make human body feel to glue discomfort such as wet, stuffy.Under mal-condition, wear air-locked clothes and climb the mountain, perspire to be difficult for discharge, freeze easily and freeze to death.This shows the importance of waterproof moisture permeating fabric.Regrettably, the waterproof fabric majority of China all is airtight not wet thoroughly at present, belong to low grade products, even being known as the coated fabric of energy Waterproof Breathable also is that light rain does not leak big rain drain, this is being subjected to considerable restraint aspect dress and the use, urgently the wait in expectation appearance of real waterproof moisture permeating fabric of people, although the external and domestic waterproof moisture permeating fabric that adopts microporous membrane to make that occurred in recent years, but owing to make the washing resistance performance of this fabric relatively poor in existing problem aspect Compound Machining and the adhesive, flexibility is relatively poor, and is especially more obvious in extremely cold area.
Summary of the invention
The purpose of this invention is to provide a kind of production method that is used for the laminated shell fabric of all-weather clothes, this method is to have the microporous membrane of waterproof, saturating wet, windproof performance, by the adhesive and the different process of different conditions, be compounded to form laminated fabric with different structure level with the variety classes fabric.

2Described surface layer fabric is cotton, hairs natural fabric, or terylene, nylon-type chemical fibre uni-material fabric, or blended fabric;
B, the microporous membrane of rolling is installed in moving back on the film machine before the compound station, moves back film by the speed of 5-50 meter per second, through sided corona treatment, the voltage of sided corona treatment is the 5-20 kilovolt to described microporous membrane earlier, and the time is 1-20 second; Described microporous membrane is the film of polytetrafluoroethylene (PTFE), polyester, polyurethanes;
C, at compound station, have the surface layer fabric of adhesive and microporous membrane constant speed and enter set composite after overlapping, handle being combined into one through lamination and heat baking, temperature that its heat baking is handled is 100-200 ℃, the best is 130-180 ℃, and the time that its heat baking is handled is 20-90 second.
Described adhesive is the PUR of modified polyvinylalcohol (EVA), low density polyethylene (LDPE) (LDPE), polyamide (PA), polyester (PES), polyurethane (PU) type, two point method by powder point, dusting, slurry point, slurry point and dusting combination is fixed on the fabric, its melting range is 100-170 ℃, the best is 120-160 ℃, and melt index is 15-30 gram/10 minutes.
Compared with the prior art the present invention has following advantage:
1, adopt laminated fabric that microporous membrane produced to have waterproof, multiple function such as saturating wet, windproof and warming, the clothes that utilize this lining to make have one-object-many-purposes.
2, adopt selected dry method or wet method combination process, easy to process, and can carry out the compound of the different numbers of plies according to final requirement, also can carry out compound with dissimilar fabrics.
3, adopt dissimilar PUR or adhesive, easy to use, effective, satisfy different occasion needs.Soft feel can use organic silicon adhesive if desired, can not harden even wear still under subzero 40 ℃ of conditions.
4, adopt physics or mechanical means water repellent fabric to be handled the adhesion strength that can improve fabric and film.
5, adopt the low microporous membranes such as polytetrafluoroethylene (PTFE) of Corona discharge Treatment surface tension can on the basis that does not reduce its proper property, reduce compound difficulty, strengthen the adhesion strength of compound fabric, improve the washing resistance performance of laminated fabric.
