Abstract

The invention relates to a production technology of a nylon 6 fine denier network stretch yarn. The production technology of the nylon 6 fine denier network stretch yarn suitable for a hydraulic loom comprises the steps that after a raw POY (Pre Oriented Yarn) is put on a raw yarn shelf, and the POY passes through a first roller, a heating box, a cooling plate, a false twister, a second roller, an oiling device and a winding roller in sequence; the production technology is characterized in that a network device and an auxiliary second roller are arranged between the second roller and the winding roller, the stretch yarn between the second roller and the winding roller passes through the network device, the auxiliary second roller and the oiling device in sequence, wherein the distance between the auxiliary second roller and the second roller is 0.2-0.4m, and the linear speed of the auxiliary second roller is less than that of the second roller. Network points of the nylon 6 fine denier network stretch yarn produced by the technology are distributed uniformly and stably, so that the nylon 6 fine denier network stretch yarn is high in strength, good in cohesion and low in bulkiness.

Description

technical field [0001] The invention relates to the field of textile raw material processing, in particular to a production process of nylon 6 fine-denier network elastic yarn suitable for water-jet looms. Background technique [0002] With the rapid development of the global economy and the improvement of people's living standards, people's demand for clothing is shifting to high-grade textile fabrics such as comfort and softness. Traditional nylon FDY (fully drawn yarn) woven fabrics are hard and soft. Elasticity and other shortcomings, and nylon elastic yarn clothing fabrics have better softness, higher hygroscopicity than other chemical fiber fabrics, and variety of colors. The woven fabrics in the high-end field are gradually replaced by nylon fine denier elastic yarn fabrics. [0003] Ordinary nylon elastic yarn is used in the weaving process of water jet looms, because of its bulkiness, poor cohesion, and low strength, it is easy to cause a large amount of short piles...
