This invention provide a snow floss and produce technics .The produce anti pilling is strong, still have excellent elasticity, droop capability, the trait of washed by machine. Especially the little ball rises after wear can be opened automatically after washed by machine and floss sense become better. This snow floss have trait: a, compare with common gauze of the same branch and slender, resist teaseling is better one level; b, compare with common gauze of the same branch and slender, flexibility is better about 20-80% and mightiness descend 15-20%; c, compare with former gauze fell branch heighten 3-15%, weightlessness about 10-40%,gauze branch boost 10-20; d, after washed by machine and washed by hand, the little ball can open automatically; e, after slopwork, the area minification is in 1.5-5%; f, in naturally state, the chubbiness is 115%-170% about former gauze. The technics process is: wash line - pretreatment- weightlessness manage-escaping from chlorine-enzyme manage -flush-coloration former manage-back settle -dehydrate and drying.

The invention provides a production method of dustless cloth with high shrinkage and high dust removing efficiency as well as the produced dustless cloth. The production method comprises the following main steps: polyester / nylon superfine fiber yarns are woven to gray cloth by using a knitting machine; the gram weight of the produced gray cloth is 130-180 g / m2; the gray cloth is poured in a dye vat by the bath ratio of 1: 5-7; penetrating agent, sodium hydroxide, EDTA-4Na and degreasing agent are added in the dye vat; the gray cloth is cleaned in a manner of discharging while washing; acetic acid is added for cleaning again; splitting agent is added for treating, and the cleaning is performed; soaping agent is added; and the gray cloth is cleaned again in the manner of discharging while washing. According to the production method of the dustless cloth with high shrinkage and high dust removing efficiency provided by the invention, the produced dustless cloth has excellent absorbability and good dust and dirt removing effect.

The invention discloses a waterproof and air-permeable superfine fiber suede leather and its preparation method and application. The preparation method includes the following steps: soaking the sea-island type non-woven fabric in impregnating liquid containing polyurethane resin for waterproof and air-permeable leather, Control the liquid content at 80-100%, then scrape off the resin on the surface of the sea-island type non-woven fabric, and obtain an impregnated base cloth after coagulation and washing with water; put the above impregnated base cloth into toluene for weight reduction to obtain a primary base cloth; The above-mentioned original base cloth is post-treated to obtain the above-mentioned waterproof and air-permeable microfiber suede. The invention makes the prepared suede leather have excellent water-resistance and hydrophobicity; during the wet solidification process, the resin part forms a three-dimensional interpenetrating hole structure, and the hole diameter is small, which satisfies the easy passage of water vapor; and the adhesion between the resin and the fiber, Avoid the presence of large pores. When this product is used in microfiber suede, it achieves both water resistance and air permeability, and its production is easy to operate.

The invention discloses a sea-island ultrafine fiber, polyurethane leather and base fabric thereof and preparation method. The sea-island ultrafine fiber is composed of sea component and island component; wherein the sea component is low density polyethylene, the island component is polycaprolactam, and the mass ratio of the sea component and the island component is 70:30 to 75:25. The preparation method includes that the sea-island ultrafine fiber is composed of the components by the mass ratio and is prepared by conventional technology. The polyurethane leather and base fabric thereof related by the invention are all prepared by the sea-island ultrafine fiber of the invention, and conventional preparation technology is adopted. The sea-island ultrafine fiber of the invention can recyclerelated sea phase material and reduce production cost when being used for preparing polyurethane leather and base fabric thereof.

The invention relates to a velvet finishing agent for synthetic leather and a preparation method thereof. The velvet finishing agent consists of the following raw materials in parts by weight: 80-120 parts of polyurethane resin, 3-10 parts of dry smooth wax powder, 2-8 parts of silicon dioxide extinction powder, 6-15 parts of glass microspheres with particle size of 5-60 microns, 1-6 parts of epoxidized soybean oil, 1-6 parts of phenmethyl silicon oil, 1-6 parts of plasticizer, 30-60 parts of dimethylformamide, 30-50 parts of butyl acetate, 20-40 parts of methylal and 20-40 parts of dimethylbenzene. The velvet finishing agent for synthetic leather provided by the invention has low cost and good velvet feel, can be used through multiple technologies such as roller painting, printing and the like, and is widely applicable. In the invention, a preparation technology of uniformly dispersing before grinding and filtering is adopted, and the prepared finishing agent can obtain more delicatevelvet feel; and moreover, as the yangbuck powder requiring accurate temperature control and long-time foaming is not used, the preparation is easier.
