Ways To Improve Fabric'S Added Value...

With the rapid development of modern society and the improvement of people's living standard, people are more and more fond of functional fabrics.

Therefore, giving fabrics different functions will be the most powerful weapon to enhance the competitiveness of fabrics.

What are the ways to improve fabric added value?

Xiaobian briefly introduces several points.

(1) starting from raw materials, developing differentiated products, such as Japan's crabo company, buying large quantities of farmland in the West Indies to start farms. After repeated selection and cultivation, the new cotton varieties with the longest fiber length and the largest strength are known as super cotton. The length of single fiber is 4.2 to 4.5cm and spun into L 94tex (300 British branches), breaking through 2.43 to 2.33tex (240 to 250 British branches).

This kind of hyper cotton has excellent whiteness, smoothness and super softness, which can be spun to be finer than silk and be woven into a superior cotton fabric better than silk.

Using the super long cotton in India, the Japanese compress company spun the cotton yarn with very low linear density. After making the fabric, the fabric is luring, with little fluffy and very soft.

The first textile company of Japan uses the high-grade cotton produced in Xinjiang to weave it into fabric. After that, it is called "the western region". Its gloss is plump and its handle is soft.

(2) the use of bipolishing finishing has made cotton fabrics look fresh. Danish Novo Nordisk has introduced a novel cotton fabric processing method called biological polishing.

It uses natural enzyme Cellusoft to remove the hairy fiber ends on the surface of cellulose fibers.

Biological polishing can be carried out in any wet processing stage of the fabric.

After bipolishing, the cotton fabric surface became smoother, eliminating the roots of easy pilling, and improving hand feel, drapability and absorbency.

Bio polishing can improve the appearance of fabrics for a long time.

(3) developing differentiated dyed fabrics, and washing the jeans and dyed silk fabrics at the same time, indicating that the dyeing and dyeing processes of cotton fabrics have become the pursuit of a considerable number of consumers.

Now, the washing process of stone mill is evolving into enzyme washing.

Europe and the United States also use uneven dyeing machines, different sprinklers and processes to make colourful dyeing processes such as coloring, marking and coloring.

Various cationic additives have been developed for cationic modification of cotton fibers, so that cotton fibers can be dyed with commonly used dyes, so as to develop imitation jeans, snowflakes, imitation corrugation, shades, discoloration and different dyeing products.

Special processing of cationic modified cotton fibers has also been successfully carried out abroad.

Suitable cationic agents, anionic softeners and treatment methods can be used for excellent special processing (such as super soft, durable water repellent, durable antistatic, durable flame retarding, etc.).

(4) develop differential finishing to give cotton fabric some special function or versatile function.

The current international market demands that cotton fabric has the following functions: weight, cold, compression, resilience, smoothness, bump, smoothness and smoothness. In terms of motor function, it has fabric size stability, flexibility, fitness, drapability and antistatic properties. It has thermal insulation, flame retardancy, aeration, moisture absorption, moisture release, permeability, water absorption, water release, anti allergy and antibacterial properties, antifouling, heat resistance and so on.

The following cotton finishing techniques have attracted much attention.

Ultra soft processing: Europe and America compete with Japan to develop super softeners for cotton.

If cotton fabric is treated by liquid amino denatured polysiloxane SandopermME, it has durable soft style and resilience.

Durable water repellent processing: fluorine repellent is mostly dangerous goods because of organic solvents.

To this end, the Japanese Miki research industrial company launched a non hazardous fluorine emulsion LiguenparanFG - 50N.

The cotton fabric can be endowed with durable water repellency by combining it with crosslinking agent.

Antibacterial and deodorizing processing: the aim is to inhibit the propagation of microbes pferred to textiles and to cut off the source of odor.

In recent years, the newly developed antibacterial and deodorizing processing is aimed at preventing MRSA from being one of the goals.

MSRA is the abbreviation of Methicillin Resistant StaphlococcusAureus, referring to Staphylococcus aureus, which is resistant to methicillin.

This bacterium has been found in human skin.

The antibacterial agent is represented by two phenyl ether system and organosilicon quaternary ammonium salt.

Recently, in the case of people's thinking of nature, the natural antibacterial and deodorant such as Luo Han tar, juniper alcohol, Artemisia argyi and deacetylated chitin developed rapidly.

They are nontoxic, inhibit the propagation of harmful microorganisms, and give cotton fabrics a sense of cleanliness and comfort.

Shape stable processing: cotton fabric is easy to contract after washing, especially cotton knitted fabric.

The latest experience in foreign countries shows that after the cotton knitted fabric is rerolled by 2D resin and then redried, the loosening, drying and over feeding can improve the fabric's stability.

Flame retardant processing: take the fire retardant processing of cotton spinning company in Japan's spinning and weaving company as an example, the flame retardant mechanism is: Proban molecules which become inactive polymers inside the cotton fibers. Once exposed to fire, they can be decomposed into phosphorus and nitrogen, carbonizing cotton fibers and forming polyphosphoric acid to obscured the oxygen in the air, so as to prevent the effect of delay burning.

The flame retardant does not produce harmful gas containing cyanide and chlorine in the fire.

UV shading processing: UV shielding processing of foreign cotton fabrics is prevalent in the light of ultraviolet radiation harmful to human body.

The processing agents used for UV shielding are UV absorber, ultrafine particle ZnO and so on.

The LiguenresinUVC system developed by Miki Research Institute, Japan, contains UV Absorbents, and is compatible with polyurethane crosslinker. Its washability is excellent.

Protein modification processing: in Japan, some people dissolve the ultra micronized cellulosic protein water, and coat the cellulose fiber fabrics such as cotton, so that the fibrin protein penetrates to the depths of the fiber, so that the processed cotton fabrics have moderate heat preservation, moisture retention, permeability and baby skin soft feel.

Processing of Melocotton: using ImpranilDispersion developed by Bayer company (water dispersible polyurethane resin) and TasoftalMCN (microemulsion amino organosilicon), cotton fabric is made by rolling and baking a emery sand to make cotton fabric spread over soft hairs.
