Nylon 6DTY refers to nylon 6 elastic yarn (nylon high elastic yarn, nylon filament yarn), which has certain elasticity and is mainly used for knitting socks, underwear, gloves and so on. The scientific name of nylon and polyamide fiber is the general name of polyamide fiber produced in China. Internationally known as nylon. It has high strength, wear resistance and good resilience, and can be used to make all kinds of clothes and knitwear by pure spinning and blending. The main varieties are nylon 6 and nylon 66, and their physical properties are similar. DTY: Drawing textured yarn, full name: DRAWTEXTUREDYARN. POY is used as the precursor (our company has various specifications of spot nylon POY), which is formed by stretching and false twisting. It usually has certain elasticity and contractibility.
At present, the variety of brocade 6dty is also dty produced by elastic machine, which has smooth surface, good curl deformation, high strength, wear resistance and good resilience, but it can't have the effect of cotton feeling (feel is similar to cotton fabric). At present, nylon 6 texturing machine only has the stretching deformation function of 1 roller and 2 roller, so it can't adjust the stretching of different materials and produce products with good cotton feeling.
Nylon 6DTY yarn is a large variety of PA6 civilian yarn, which is mainly used to make export elastic socks, elastic belt, sportswear and so on. DTY yarn is made by two steps. First, it is spun into POY, and then stretched and false twisted on a texturing machine. In the production process of nylon 6DTY yarn, the yarn rubs against the false twister, and white powder will appear on the false twister, which seriously affects the equipment operation and daily production. The production of white powder is related to the chip quality and spinning process. It is of great significance to study its composition to analyze its causes and optimize the polymerization and spinning process.
Technical realization elements
The invention aims to provide a production method of nylon 6dty cotton-sensitive yarn, which is beneficial to producing cotton-sensitive yarn with good cotton-sensitive effect. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: a production method of nylon 6dty cotton-sensitive yarn adopts two raw materials A and B with different materials, and the production is as follows: the two raw materials are led out from a precursor frame, cut by a knife, passed through an additional roller of 1. 1. After passing through 1 roller, the two raw materials enter the hot box with a set draft, then are elastically loaded by a false twister, then pass through the second roller, and then enter the air network pipeline between the second roller and the 2a roller at a set overfeed rate for post-spraying; After passing through the roller for 2 years, it enters the winding area for winding and forming, and the required cotton yarn is obtained.
