Problems solved by technology

[0004] Although jade fiber has cooling properties, the temperature of the fabric made of this fiber will continue to rise as it contacts the skin after being worn for a long time, making it difficult to maintain a lasting cooling property

Embodiment 1

[0048] The cooling masterbatch formula is: 65 parts by weight of PA6, 10 parts by weight of jade powder, 3 parts by weight of zirconia powder, 8 parts by weight of silicon dioxide powder, 1 part by weight of stearic acid dispersant, modified polyphenylene 2 parts by weight of ethylene dispersant, 2 parts by weight of low-molecular wax dispersant, and 1 part by weight of titanate coupling agent.

[0049] Nylon-based cooling fiber, made by the following methods:

[0050] (1) Use cooling masterbatch as raw material to make slices;

[0051] (2) Dry the slices: the drying temperature is 150°C, the drying time is 10 hours, and the dew point of the compressed air during drying is -58°C, so that the water content of the slices is reduced to below 30PPM;

[0052] (3) Spin the slices through the spinning box to make nylon-based cooling fibers: the slices are heated in the spinning box to form a thin stream of spinning melt, which is sprayed out from the spinneret of the spinning box ,...

Abstract

The invention relates to functional fiber and particularly relates to polyamide-based cooling fiber and yarn. The polyamide-based cooling fiber is prepared by the following method: (1) taking cooling masterbatch as a raw material, and cutting the cooling masterbatch into slices; (2) drying the slices; and (3) spinning the slices through a spinning box to produce the polyamide-based cooling fiber, wherein a formula for the cooling masterbatch comprises the following components: PA6, jade powder, zirconium dioxide powder, silica powder, stearic acid dispersant, polystyrene dispersant, low molecular wax dispersant and titanate coupling agent. The polyamide-based cooling fiber and yarn have the functions of fast heat absorption and fast heat dissipation so as to ensure lasting cooling characteristic.

Description

technical field [0001] The invention relates to functional fibers, in particular to a nylon-based cooling fiber and yarn. Background technique [0002] With the continuous refinement of the social division of labor, many production areas have higher and higher requirements for clothing. In addition to the dust-free production workshop, operators are also required to wear tight clothes from head to toe, which will inevitably bring new benefits to the comfort of operators. Inconvenient, especially in hot summer, this problem is more obvious. In order to improve the wearing comfort of clothing, people have carried out a lot of comfort research on fabrics, among which the research on cooling fabrics applied to protective clothing is undoubtedly a hot topic in recent years. In order to solve the above problems, people have thought of developing a fiber material with a cooling function——jade fiber. Jade in jade fiber is rich in minerals. Long-term application on human skin can i...
