Embodiment Construction

[0015] specific implementation plan

[0016] The coated fabric of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The invention adopts the release paper dry method transfer coating technology, and the product structure is two layers of coating and one layer of base cloth. Its processing steps are as follows:

[0018] 1. Base fabric 3: Cotton fabric or sea-island fiber fabric is treated with flame retardant and anti-mildew treatment as the base fabric of the coated fabric.

[0019] 2. Slurry preparation:

[0020] (1) Bottom layer slurry 2: Mix polyurethane adhesive Y-147 and dimethylformyl in a weight percentage of 85:15, stir evenly with a stirrer, and set aside.

[0021] (2) Surface layer slurry 1: Polyurethane resin I UD-8310LP, polyurethane resin IIY-208, crosslinking agent I NE, crosslinking agent II UD, accelerator I HI-215, accelerator II UD-102, barrier Burning agent TCPP, antibacterial and antifungal age...

Abstract

This invention discloses a kind of multi-layer-pasting fabric, made with the method of pasting at least 2 layers of different slurries on one layer of base cloth. The components of the slurry-pasting surface layer is (by weight): polyurethane resinI30-60%, polyurethane resin II 30-50%, cross linkerI1-5%, cross linker II 0.5-3.5%, accelerator I 0.5-10%, accelerator II 0.5-5%, fire retardant 2-5%, antiseptic and mildew preventive 1-2%, dimethyl formamide 0-2%, toluene 3-5% and methyl ethyl ketone 1-2%. The components of the slurry-pasting bottom layer is (by weight): polyurethane adhesive 80-100% and dimethyl formamide 0-20%. The coldness resistance of this invention is nice, and even at -60deg.C the paintcoat will not turn fragile, crack, get deformed or become hard. At the same time, it has the merits of aeration, fire resistance and antisepsis, with the air permeability of over 1000g / square meter, antisepsis of 1 level and the fire resistance reaching the nation standard. In a word, it is more fit to be used in cold.

Description

technical field [0001] The invention relates to a functional textile, especially a textile with functions of cold resistance, air permeability, flame retardancy and antibacterial. Background technique [0002] In the prior art, in view of people's work and life in harsh weather environments, there are further functional requirements for textiles, and some textiles with cold resistance, breathability and flame retardancy have been developed respectively, so that the fabrics are windproof, downproof, Cold-resistant and warm-keeping performance. [0003] In the published domestic patent (application number 88101574.1) and "cold-resistant and breathable coating windproof cloth" (China Science and Technology Achievement Database No.: 91218732), "Research and Development of Military Functional Textile Materials" ("Chinese Academic Papers" meeting time : May 10, 2001) functional windproof coated cloth, its performance is not suitable for use at temperatures below -20°C, otherwise ...
