Problems solved by technology

[0004] In a similar way, water or heat-dissipating phase-change materials are sealed in specific bags or tubular spaces, such as patents US2006276089, US2006064147, US2005284416, US6134714, US5415222, etc., using water-repellent air-tight materials to seal water or phase-change materials to avoid liquid Loss of heat dissipation material; however, under long-term use, due to external friction and pressure, there will still be water leakage problems. The use of phase-change materials cannot maintain long-term effects, and cooling can only be achieved after the phase-change materials return to a solid state The role of metal fiber weaving with high heat conductivity can make textiles with long-term cooling effect, such as patent IT1251745, due to the high cost and poor softness of metal fibers, the practical application of such cooling textiles is not good.

Abstract

Provided are a temperature-reducing and cooling fiber, a fiber cooling in wind, a method for preparing a temperature-reducing and cooling textile fiber, a temperature-reducing and cooling textile, and a method for detecting a temperature-reducing and cooling fiber. The temperature-reducing and cooling fiber comprises: a conventional textile fiber and a nanometer unit accounting for 0.1-4% (part by weight) of a total weight. The nanometer unit comprises microparticles with a particle size of 300-8000 nanometers. The microparticles comprise titanium, neodymium, or a mixture thereof.

Description

technical field [0001] The invention relates to a chemical fiber, in particular to a cooling fiber, a preparation method of the fiber 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 produced by the difference can achieve the effect of reducing the body heat temperature; such as patents US4342203, WO2007088431, JP4209809, US2007050878, US...
