Abstract

The invention discloses a finishing agent for an acrylon fabric. The finishing agent comprises the following raw materials in parts by weight: 40-50 parts of tetracarboxydiphthalic ether dianhydride, 2-8 parts of aluminum oxide powder, 10-13 parts of mica powder, 10-20 parts of tert-butyl peroxy benzoate, 20-40 parts of 2-(diethylamino)ethyl methacrylate, 20-50 parts of dibutyltin dilaurate, 10-30 parts of polypropylene, 20-40 parts of potassium peroxodisulfate, 10-50 parts of n-butyl methacrylate, 20-30 parts of polyethylene glycol, 10-15 parts of zinc sulfate, 4-20 parts of glass fiber, 10-18 parts of initiator, 5-15 parts of auxiliaries and 40-50 parts of water. The acrylon fabric treated by using the finishing agent disclosed by the invention has the high breaking strength of 80.6g / tex and the stretch rate of 92-95%, so that the breaking strength of the acrylon fabric is greatly improved and the service life of the acrylon fabric is prolonged.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a finishing agent for acrylic fabrics. Background technique [0002] Acrylic is polyacrylonitrile fiber. Synthetic fibers made of polyacrylonitrile or acrylonitrile copolymers with an acrylonitrile content greater than 85% (mass percentage). Commonly used second monomers are non-ionic monomers, such as methyl acrylate, methyl methacrylate, etc., and the third monomers are ionic monomers such as sodium propylene sulfonate and 2-methylene-1,4- Succinic acid, etc. The performance of polyacrylonitrile fiber is very similar to that of wool, with good elasticity. When it is stretched by 20%, the rebound rate can still maintain 65%. It is fluffy, curly and soft, and its warmth retention is 15% higher than that of wool. The strength is 22.1~48.5cN / dtex, which is 1~2.5 times higher than that of wool. Excellent light fastness, one year of exposure in the open air, the strength will only decrease...
