Textile Knowledge: Methods Of Textile Functional Finishing

At present, our country develops

The main functions are: far-infrared fiber, anti ultraviolet fiber, negative ion fiber, antibacterial deodorant fiber, photocatalytic fiber, flame retardant fiber, fragrance fiber, color changing fiber, radiation protection fiber, magnetic fiber, nano fiber, conductive and antistatic fiber. These functional fibers will undoubtedly provide powerful raw material support for the development of functional textiles.

Ordinary textiles can be assigned special functions through special finishing methods to meet certain special requirements. The functional finishing of textiles has strong purpose, good effect and high added value of products.

Functional finishing of textiles requires good environmental protection, safety in production and operation, and innocuity, no side effects and good functional durability.

The methods of textile functional finishing include physical finishing, chemical finishing and biological ecological finishing. Among them, physical finishing is divided into three methods: dipping, dip rolling and coating.

Physical finishing.

Impregnation method: a multi-functional finishing agent which forms homogeneous solution with finishing agent and solvent. With the solution penetrated into the gap between fibers in the fabric, dyed fur coat should be strictly checked for chromatic aberration or odor.

A leather coat with a focus on the clarity of the flower spots.

The sheepskin coat is obviously good with short hair and firm curved flowers.

It interacts with the surface of the fiber to form functional intermolecular adhesion on functional textiles.

Because the interaction force between finishing agent and textile is weak, the fastness is not high, and it is easy to lose the unique function by the influence of external and usage.

The rolling method will be cleaned up.

After immersion in the solution, the additives are extruded into the textile fiber gap with the solution.

The rolling method is simple and easy to operate, and can be realized by ordinary sizing equipment. The cost is low, and its significance to enterprises is more important in the risk management of marketing channels. Because logistics has been separated from many enterprises for its importance, it is managed separately.

But fabric feel and style characteristics are slightly affected by the solution.

The coating agent will be applied to the textiles and baked. The finishing agent can be partly grafted with the textile fibers, or the polymerization agents can be polymerized together to form a more stable film on the outer surface of the functional textiles.

This kind of finishing method has high fastness, good durability and low cost. The drawback is that the style of textile and hand feeling finishing agent have great influence.

Chemical finishing.

The chemical reaction of monomers and monomers with some functions can be carried out by copolymerization and grafting, so that fiber materials and functional materials are closely combined to form a new functional material.

Chemical finishing has permanent performance, but this method is highly technical, costly and difficult to produce.

Bio ecological finishing.

Bioecological finishing is a new method of finishing in recent years, and bioactive enzymes are widely used to carry out textile processing.

This kind of finishing has the characteristics of high safety, little environmental impact and good finishing effect.

Because biological ecological finishing relies on biochemical action, although the finishing effect is good and the function is durable, it is difficult to produce and high cost, and the influence on the handle and style of the textile is different from that of the biological enzyme.
