Intelligent temperature-adjusting viscose fibre and its production

Abstract

A phase-variable material micro-capsule as temperature-adjusting functional material, an intelligent temperature-adjusting viscose fiber and its production are disclosed. Dry breakdown strength is >=1.42CN / dtex, wet breakdown strength is>=0.64CN / dtex; It consists of cellulose 84.7-92.75wt%, micro-capsule 5-30wt% and water-content 7-15wt% and oil solution 0.15-0.30wt%. The fiber coagulation heat-liberation enthalpy valueDeltaH>=1.0J / g, melt heat-adsorption enthalpy value DeltaH>=1.0J / g. It is non-toxic, has better adaptability and no harm.

Description

technical field The invention relates to the production of intelligent temperature-regulating viscose fiber and its method by using phase-change material microcapsules as additives. The raw materials are obtained through a certain production process for industrial production of intelligent temperature-adjusting viscose fiber. technical background At present, with the rapid development of science and technology, people's living standards are gradually improving, and the requirements for the comfort of textiles are getting higher and higher. Intelligent temperature-adjusting viscose fiber follows this development trend and provides people with a kind of fabric that can release heat when it is cold and absorb heat when it is hot. Thermal smart textiles that eliminate the feeling of hot and cold due to temperature changes. Enhance the wearability of textiles. American Outlast Company and Japanese Yamato Company have also successively developed phase-change temperature-regula...
