Abstract

The invention relates to chemical fibres capable of quickly cooling in wind and a textile contianing the same. The chemical fibre comprises ordinary chemical fibres and a nanometre unit which accounts for 0.1 to 0.4 percent of the total weight of the chemical fibers, wherein the nanometre unit comprises 300 to 8,000nm micro particles; and the micro particles mainly comprise Zn or Al or Ca or Na or P or La, or a mixture of Zn, Al, Ca, Na, P and La. Because the 300 to 8,000nm micro particles are added in the ordinary chemical fibres, the chemical fibres of the invention can quickly cool in wind; compared with the traditional cooling fibres, the chemical fibres of the invention have the advantages of relatibvely low manufacturing cost, simple manufacturing process, easy industrial production and the like; and at the same time, the chemical fibres of the invention can be prepared into a new cooling fibre fabric with excellent quality and the new cooling fibre fabric achieves the effect of cooling and making users feel cool during indoor and outdoor activities, exercises, outdoor works and the like in summer.

Description

technical field [0001] The invention relates to a chemical fiber, in particular to a chemical fiber which is rapidly cooled by wind and a textile containing the fiber. Background technique [0002] At present, the early production of general cooling textiles is mainly based on heat exchangers and power transmission heat transfer fluids, such as US patents US5062424, US5092129, US5263336, US4738119, etc. These technical solutions are only used in special working environments and are not suitable for daily wear applications. . [0003] Furthermore, in addition to the use of pipelines, the interlayer design simplifies the complex layout of pipelines. Through the multi-layering of air-permeable, impermeable and water-permeable layers, there is a coherent space with a specific structure between the two layers. The airflow generated by the difference can achieve the effect of reducing the body heat temperature; such as patents US4342203, WO2007088431, JP4209809, US2007050878, US2...
