Abstract

The invention discloses a spun silk / Outlast blended fabric with temperature regulating function and a preparation method thereof. Outlast short fibers are blended with spun silk fibers at a blending dry weight ratio of 20% to 60% to make linear densities of 83.3dtex and 166.7 dtex spun silk / Outlast blended yarn single yarn, and then two single yarns are combined and twisted to obtain 166.7dtex and 333.4dtex spun silk / Outlast blended yarn strands; the spun silk / Outlast blended yarn strands are used Threads are used as warp and weft yarns. The warp density is 300-600 / 10cm, the weft density is 120-300 / 10cm, and the fabric weave is 2-4 pieces to make fabric gray fabric, which is then scoured, washed and washed in four steps. Drying and setting to make finished fabrics. According to the method provided by the invention, the heating rate of the fabric at 20°C to 40°C and the cooling rate at 20°C to 10°C are obviously lower than those of pure spun silk fabrics, and it has a good temperature adjustment function, making it difficult for the human body to feel heat in a high temperature environment. It is not easy to feel cold in low temperature environment. At the same time, this kind of fabric also has the advantages of good hygroscopicity, good air permeability and moisture permeability, softness and comfort, and is a kind of functional silk fabric.

Description

technical field [0001] The invention relates to a temperature-regulating fabric and a preparation method thereof, in particular to a temperature-regulating fabric blended with spun silk and Outlast fiber and a preparation method thereof. Background technique [0002] Outlast heat storage and temperature regulating fiber is a new type of "smart" fiber, which was successfully developed by Outlast in 1988. It was first used for commercial use in 1994, used for outdoor clothing in 1997, and is now widely used in fashion and bedding. The temperature adjustment effect of Outlast fiber is achieved by using microcapsule technology to implant heat-sensitive phase change material (PCM) into the fiber. This material can absorb, store and release a large amount of heat in the form of "latent heat". It can be based on The change of the external environment temperature is transformed into solid and liquid, so as to achieve the effect of buffering the temperature change. [0003] Initiall...
