Abstract

The invention relates to a warm-keeping and moisture-conducting multifunctional nylon 6 fiber and a preparation method thereof. The preparation method comprises the steps that nylon 6 serves as a rawmaterial, a spinneret plate with a similar H-shaped spinneret hole cross section is adopted for spinning, and the warm-keeping and moisture-conducting multifunctional nylon 6 fiber is prepared. The similar H shape is composed of a curve m, a curve n and a curve t, m and n are symmetrical, t is connected with m and n at the same time, the I ends of m and n are located on the same side, and the II ends of m and n are located on the same side; and the distance between the end I of m and the end I of n is 0.20-0.30 mm, and the distance between the end II of m and the end II of n is 0.35-0.50 mm. The cross section of the monofilament of the finally prepared warm-keeping moisture-conducting multifunctional nylon 6 fiber is similar to A shape, and the similar A shape is composed of a single bending curve and a curve located in the single bending curve. The process is simple, production can be achieved on the basis of an original device, the fibers can be endowed with excellent warm-keeping and moisture-conducting functions, and the method can be applied to the fields of clothing fibers, household textiles and the like.

Description

technical field [0001] The invention belongs to the technical field of textile fiber material preparation, and relates to a heat-retaining and moisture-conducting multifunctional nylon 6 fiber and a preparation method thereof. Background technique [0002] With the advancement of science and technology, the development of the world economy, and the improvement of people's living standards, a yearning for leisure, the pursuit of a comfortable and relaxed living environment is being set off, making the world's clothing is gradually evolving unconsciously, in order to adapt to people's "new, strange According to the consumption habits of ", special and comfortable", the weaving industry is also doing everything possible to design various fabrics that meet people's needs, so the development of new fiber materials has become an urgent need. In order to enhance the thermal insulation effect of clothing fabrics, the conventional practice in the market is to add layers and thicken t...
