Nylon Textured Yarn

A nylon textured yarn is made for helping the spin-draw process is necessary in order to meet specific requirement and then to improve the characteristics of nylon fabric soft, bulky, cotton-like touch. Nylon textured yarn were produced by means of this process. Those apparel applications in such like tight-fitting lingerie, panty hose, yoga dressing and other sportswear with stretch effect made of nylon textured yarn will provide people more comfortable.
Simply describe as below：

How To Make Nylon Textured Yarn

The materials of nylon textured yarns are the nylon chips, are placed in the hopper at the top, and then heated to 216℃ under a pure nitrogen atmosphere to prevent oxidation. The heat melted the nylon chips, then pumped down through the spinning apparatus which melts of nylon polymers extrudes the molten polymer from the spinneret via the extruder and drawing device spinning the partially oriented yarns (POY), which were then collected on the windup bobbin. As long as there are manmade fibers, there will be the attempt to give manmade fibers a natural fiber-like character. No exception of nylon textured yarn. Texturing is a refinement step that transforms POY into draw nylon textured yarn (DTY), into attractive and individual products.

The Steps of Producing The Nylon Textured Yarn

It’s complicated to make the nylon textured yarn. A continuous high speed spin-draw-false twist texturing process for producing a nylon textured yarn comprises the steps of
1、 Melt-spinning a plurality of nylon filaments from nylon polymer
2、 Cooling the filaments and combining them to form a yarn
3、 Controlling the processing conditions of the nylon polymer of step, such that the relative viscosity of the yarn formed in step
4、 The degrees of making nylon textured yarns is at least 45
5、 partially drawing the yarn at a draw ratio of from 2.3 to 3.5 and a temperature of at least 50℃.
6、 Simultaneously false twist texturing and further drawing the partially drawn yarn in a draw-false twist texturing zone at a draw ratio of from 1.1 to 1.5.
7、 Withdrawing the nylon textured yarn at a very high speed rates. The process is particularly useful for the manufacture of nylon textured yarn having a linear density in the range of from about 10 dtex to about 50 dtex.

Nylon Fabric - The Origin of Nylon 6

Nylon fabrics made of nylon 6 yarn begins as pure caprolactam. As caprolactam has 6 carbon atoms, it got the name Nylon 6.When caprolactam is heated at about 533 K in an inert atmosphere of nitrogen for about 4-5 hours, the ring breaks and undergoes polymerization. Then the molten mass is passed through spinnerets to form fibers of Nylon 6. During polymerization, the peptide bond within each caprolactam molecular is broken, with the active groups on each side re-forming two new bonds as the monomer becomes part of the polymer backbone. Unlike nylon 6.6, in which the direction of the amide bond reverses at each bond, all nylon 6 amide bonds lie in the same direction. The nylon fabric is made from nylon 6.
