Antibacterial and antistatic PTT fiber wool-like double-faced woolen cloth and processing and finishing method thereof

Abstract

The invention discloses antibacterial and antistatic PTT fiber wool-like double-faced woolen cloth and a processing and finishing method thereof.The processing and finishing method comprises the following steps that S1, pretreatment is conducted, specifically, ester bonds on the fiber surface of the wool-like double-faced woolen cloth are hydrolyzed to generate carboxyl, and standby wool-like double-faced woolen cloth is obtained; s2, modification treatment: after washing the standby wool-like double-faced woolen cloth, grafting tyramine to obtain modified wool-like double-faced woolen cloth containing phenolic hydroxyl groups; and S3, finishing treatment: taking the modified wool-like double-faced woolen cloth, washing, carrying out free radical graft polymerization on the modified wool-like double-faced woolen cloth and a vinyl quaternary ammonium salt monomer under a catalytic system so as to graft polyethylene quaternary ammonium salt macromolecules on the surface of the polytrimethylene terephthalate fiber, washing, and drying, so that the modified wool-like double-faced woolen cloth is obtained. High temperature and strong alkali are not needed, the treatment temperature is low, production steps are simple, production energy consumption is low, damage to the fibers is reduced, grafting of vinyl quaternary ammonium salt molecules on the surfaces of the fibers is achieved, the antistatic and antibacterial performance of the fibers is effectively improved, diffuse reflection light of the fabric is increased, and the luster of the fabric is closer to that of wool products.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to an antibacterial and antistatic PTT fiber wool-like double-faced wool and a processing and finishing method thereof. Background technique [0002] Double-faced wool is a woolen product with the same front and back styles processed from wool. Compared with ordinary woolen fabrics, double-faced woolen fabrics not only have a fine and soft texture, good warmth retention and super elasticity, but also have unique shrinkage and wrinkle resistance, with a delicate and smooth feel, which is deeply loved by consumers. Because all-wool double-faced wool has high requirements on the quality of wool fiber raw materials, and the weaving, dyeing and finishing processes are complicated, its production cost is relatively high. In recent years, using synthetic fibers (such as polyester, nylon and acrylic fibers) as raw materials, weaving with front and back weaving on the s...

Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of antibacterial and antistatic PTT fiber wool-like double-sided wool and its processing and finishing method, to solve the smooth surface of the wool-like double-sided wool processed by PTT fiber in the prior art, there is mirror light, and static electricity is easy to accumulate. The antibacterial performance is low. Alkaline treatment is used for wool-like double-sided finishing to improve surface roughness and increase fiber hydrophilicity. There are technical problems such as difficult to control the treatment process, easy to cause fiber damage, and no improvement in antibacterial performance.
