Abstract

The invention relates to nylon DTY (draw textured yarn) with temperature adjusting performance. The nylon DTY with temperature adjusting performance is prepared from raw materials in parts by weight as follows: 120-150 parts of nylon chips, 30-45 parts of temperature adjusting fibers, 15-25 parts of modified nanoscale molybdenum oxide, 4-6 parts of triallyl isocyanurate, 5-10 parts of alga functional masterbatch and 18-27 parts of isophthalic acid modified nano-titanium dioxide. The alga functional masterbatch can combine the raw materials very well, and has a synergistic effect on performance of the components. Isophthalic acid is adopted to modify titanium dioxide, so that dispersibility of titanium dioxide in the nylon DTY can be effectively improved, and the temperature adjusting effect of the prepared nylon DTY is better. The modified molybdenum oxide is adopted as a main material for heat accumulation and temperature adjustment, and meanwhile, isophthalic acid modified nano-titanium dioxide is added, so that the heat accumulation efficiency of the modified molybdenum oxide can be synergistically improved according to the ultraviolet-absorbable characteristic of isophthalic acid modified nano-titanium dioxide.

Description

technical field [0001] The invention belongs to the field of textiles and relates to a nylon elastic yarn, in particular to a temperature-regulating nylon elastic yarn with good temperature-regulating performance, good spinnability and low cost. Background technique [0002] Nylon fiber is the first synthetic fiber to realize industrial production in the world. Heat storage and temperature regulating fiber is a new type of fiber with two-way temperature regulating effect. According to the change of the external environment temperature, it can absorb heat from the environment and store it inside the fiber, or release the heat stored in the fiber, and form a microclimate with a basically constant temperature around the fiber, thereby realizing the temperature regulation function. This heat-absorbing and exothermic process of heat-storing and temperature-regulating fibers is automatic, reversible, and infinite. [0003] The difference between heat storage and temperature regu...
