Detailed Description
PVA water soluble textile staple yarn made from the PVA. PVA is polyvinyl alcohol, is one of the few properties of a synthetic biodegradable polymer materials, has been widely used in the production of various fibers, PVA film is also used as food packaging bags. Thus water-soluble polyvinyl alcohol, polyvinyl alcohol fiber which is a valuable functional differential fiber.
For the production of untwisted towel
(1) The principle of a production with a water-soluble Z twist yarn, cotton yarn and synthetic stocks, and then strand plus S twist, yarn twist and the same, therefore, to become untwisted yarn and the yarn bundle is water-soluble coating, increase the strength of untwisted yarn without sizing, can be directly weaving. Weaving is complete, PVA filament was dissolved by the scouring, cotton yarn became untwisted yarn. This method can make use of soft and untwisted yarn, finishing without using softener.
(2) process cotton, water-soluble yarn twisting → → → and weaving yarn scouring → bleaching → → → untwisted towel products printing and dyeing
(3) terry towels, two specifically recommended length of untwisted 5mm. Design untwisted towel fabric density 10% lower than ordinary towels, this effect is more fluffy, thick, indicating that cotton consumption can be reduced by 10%.
(4) on the untwisted towel ① absorbent: General towel was twisted yarn hair, hair in the post-processing is deformed, resulting in hard water absorption worse. In order to reduce the hardness, usually softener, which also makes water absorption worse. The untwisted towel and avoid the above-mentioned shortcomings.
② off on the cotton issue: some people will think untwisted fiber towels towels more than a twist off, the problem through rational design of the fineness of cotton yarn, yarn untwisting the number density of the fabric be improved.
