Abstract
The utility model relates to composite base fabric used for wet method polyurethane production of artificial leather. A knitted fabric base with high elasticity and a woven fabric base are jointed and dried by liquid glue which is composed of acrylic resin latex, glyoxal and ammonia water to form a dual-layer composite fabric base with certain dry and wet peeling strength. The utility model has the advantages of simple structure, easy processing and easy manufacture; the utility model solves the difficulty that the knitted fabric can not be used as the fabric base of the wet method polyurethane leather; the breathability and the elasticity of the polyurethane leather can be effectively improved, and use performance of the polyurethane leather can be improved. The utility model is suitable for industrialization big production to cause the application area of the knitted fabric to be widened, and the utility model is suitable for being used in the existing wet method polyurethane production process.
Description
The utility model is the compound base cloth of a kind of wet method polyurethane leather production.
Artificial leather is since this century, the forties came out, because some performance has adapted to people's demand in many aspects, demand enlarges day by day, occurs woven fabricbase PVC film leather in 1948 first, the PVC artificial leather is because its gas permeability is poor, and cold resistance is low and make it in use be subjected to many restrictions; 1963, du pont company is trial-produceed woven fabricbase wet method polyurethane PU artificial leather successfully, make quality outward appearance, feel, the sanitation performance of artificial leather all cross over major step, woven fabricbase wet type polyurethane (PU) artificial leather have good saturating wet, gas permeability, abundant, cold resistance good, anti-subduing, fine qualities such as intensity height, but because its fabricbase adopts woven cloth, thereby elasticity and flexibility are relatively poor; And looped fabric has the better elastic flexibility, but because its tensile strength is low, the washing shrinkage height in wet method polyurethane production process, easily produces contraction, fold, can't produce qualified polyurethane artificial leather.Therefore, elastomeric knitting fabricbase fails to be applied in the production of wet method polyurethane always.
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of processing technology simple, the base cloth that is suitable for as wet method polyurethane leather production usefulness easy and simple to handle.
The utility model is to adopt following proposal to realize: with the knitting fabricbase of high resiliency and woven fabricbase with the liquid sticker that propylene (80%～90%) resin emulsion and glyoxal (5%～15%), ammoniacal liquor (1%～5%) constitute close, dry formation tool is necessarily dried, the two-layer compound fabricbase of hygrometric state peel strength.
The utility model is owing to adopt a kind of base cloth that compound fabricbase certain thousand, the hygrometric state peel strength is produced as leather that has, therefore, in wet method polyurethane production technology, can bear the huge tension force of each section in the production process, guarantee fabricbase in process of production, be in smooth and even stress always, overcome the drawback of knitting fabricbase shrink, convolution, for the application of high resiliency looped fabric in the production of wet type polyester leather provides a kind of feasible base cloth, wet type polyurethane performance of leather is improved.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
Accompanying drawing is the utility model master cutaway view.
See accompanying drawing, the utility model is made up of looped fabric 1, woven cloth 2, described looped fabric 1 and woven cloth 2 through resin glue fit, dry, promptly constitute have necessarily do, the two-layer compound fabricbase of hygrometric state peel strength.
Using method of the present utility model is sketched in following:
Because looped fabric and woven cloth bilayer are fitted into an integral body, the intensity that makes compound fabricbase have woven cloth can be born the huge pulling force of generations at different levels in the wet method polyurethane production technology, guarantee that fabricbase is in smooth and even stress in process of production, overcome that looped fabric easily shrinks, the drawback of convolution; Simultaneously, the polyurethane leather that adopts compound fabricbase to produce after the dry state stripping machine is weaved cotton cloth, possesses better elastic and gas permeability, and its performance indications are as follows:
1. hot strength: radially 〉=210N/3cm
Broadwise≤150N/3cm
2. percentage elongation: radially 〉=60%
Broadwise 〉=190%
3. tearing strength: radially 〉=160N/3cm
Broadwise 〉=240/3cm
4. flexible resistance: 100,000 times (25 ℃) are flawless
5. anti-plug: subzero 20 ℃ of no breaches, soft durometer does not have significant change
6. gas permeability: can directly smog be blown over
7. hygroscopicity and poisture-penetrability: the back side water can be absorbed fully to the leather tissue and can from
The front appears
8. light weight, drapability are good, are difficult for folding, and flexibility is good.
In sum, the utility model is simple in structure, processing and manufacturing is easy, having solved looped fabric can't be as the difficulty of wet method polyurethane leather fabricbase, can effectively improve the gas permeability and the elasticity of polyurethane leather, improve the serviceability of polyurethane leather, be suitable for industrialized production, expanded the application of looped fabric, be suitable for using in existing wet method polyurethane production technology.
