Development Of PU Ultra-Thin Super Soft Garment Fabric

< p > > Description: ultra-thin new type < a href= "//www.sjfzxm.com/news/index_c.asp" > W9-5PU < /a > the research and development contents of the garment fabric project: 1. cooperate with the textile mill to develop ultra-thin and super soft, and new type of base cloth suitable for the production of synthetic leather.

< /p >

< p > 2.. Research and develop suitable PU resins and necessary auxiliaries.

< /p >

< p > 3. < a href= "//www.sjfzxm.com/news/index_c.asp" > Design > /a > and optimize the production formula so as to ensure soft and full handle when producing ultra-thin products, while maintaining the necessary physical and mechanical properties of garment leather.

< p > 4. in the synthetic leather production process, the penetration control of the coating process is very Guan Jian. Too much penetration will cause stiff hands, and too little penetration will cause poor adhesion.

< /p >

< p > in super soft super thin < a href= "//www.sjfzxm.com/news/index_c.asp" > synthetic leather < /a > production, this problem is more prominent, penetration is a little bit more, feel is hard, penetration is slightly worse, adhesion force is poor. In order to solve this contradiction, the project group collected a lot of data through laboratory test and workshop pilot test, and groped for the rule, finally through the formula modification and process parameter adjustment, the problem was solved.

< p > project difficulty: how to ensure that thin, soft and light base is not wrinkled, not broken and not narrowed in the whole production process of about 400m, but also ensures that there is a very suitable penetration point when gluing.

To this end, the project team first carried out the necessary renewal and pformation of the machinery and equipment according to the specific requirements.

< p > with the rapid change of market demand, the frequency of textile enterprises changing varieties is also increasing.

Because many enterprises can not choose the card clothing correctly, even if the new type of needle clothing is applied, it can not play a good role.

In this case, some domestic spinning enterprises have developed "universal metal card clothing".

The design of the working angle of the card clothing takes into account the requirements of chemical fiber and cotton. The adaptability is relatively flexible, to a certain extent, it can meet the needs of the modified varieties.

However, this is only an expedient measure and can not really solve the problem of "matching seats" for card clothing and yarn varieties.

< /p >

< p > foreign clothing manufacturers have made some explorations and made some achievements in this regard.

For example, a few years ago, Graff launched a newly developed camel card clothing.

The new needle clothing is very similar to the camel's hump. It is usually used as a cylinder linen on the flat type short fibre carding machine, but also as a needle roller clothing.

Camel's Xilin card clothing's hump shape design is different from that of the general metal card clothing. The surface of this kind of camel's camel's hump will form an obvious supporting action on the airflow, so that the fiber can remain on the surface of the cylinder linen and prevent the fiber from sliding toward the needle cloth, thus improving the ability of the fiber's comb and pferring to the doffer.

This new type of clothing can eliminate immature fibers, dead fibers and knots.

The camel's clothing is less than ordinary plain clothing, so fiber damage is less, which makes short fiber down.

Xilin metal card clothing of camel carding machine (P) is suitable for all kinds of carding machines. It is a new development of new card clothing for carding machine.

At the same time, it can also be applied to the thorn roller. Its advantage is that the tooth shape of the hump needle clothing can improve the pfer of fibers between the roller and the cylinder, because the fibers and impurities are kept on the surface of the needle roller, so that the number of impurities can be increased.

Such immature fibers and dead fibers are discharged early before they enter the feeding part of the carding machine.

(if this kind of immature and undesirable dead fiber is not discharged early, it will have a negative effect on the knitted fabric or machine weaving process, so that the fabric will have neps or pverse defects.

Camel type Xilin and pin roller metal card clothing can make the fiber processed well when carding machine, so that the neps of downstream products can be significantly reduced.

Practice shows that active and rational selection of advanced card clothing is an important factor in developing high performance carding machine, and can further improve product quality.
