Device and method for testing fabric contact coldness

Abstract

The invention relates to a device and a method for testing fabric contact coldness, and belongs to the field of textile engineering. The testing device consists of an outer cover, a test board, a sink, a fabric splint, a fabric surface temperature sensor and the like. The testing device of the invention has the advantages of reasonable structure, convenient use, small volume, low manufacturing cost and large-scale industrialized production; and the testing device adopts a platinum resistor with good stability and high precision as the temperature sensor, so the testing precision is improved. A cover hood made of an insulating material is arranged above a test platform so as to reduce the influence of the ambient environment on the test, reduce the heat loss caused by heat radiation of the fabric and improve the testing reliability. The testing device and the testing method of the invention overcome the defects of high technical requirement and high testing cost when testing the maximum transient heat flow Qmax of the fabric by the conventional method to evaluate the coldness of the fabric. The device and the method of the invention for testing the fabric contact coldness can be used in the field of contact coldness evaluation for the fabric.

Description

technical field [0001] The invention relates to a fabric contact cold feeling test device and a test method, which belong to the field of textile engineering. Background technique [0002] Along with the raising of living standard, the comfort of clothing is subject to people's great concern. The heat transfer performance of fabric is an important factor affecting the thermal comfort of clothing. The thermal comfort of clothing refers to the heat transfer function of fabrics, so that the human body can obtain a comfortable and satisfactory feeling in a changing environment. After the human body wears clothes, there is always an energy exchange between the body and the environment. The comfort of the human body depends on the balance of energy exchange between the heat generated by the human body itself and the heat emitted to the environment. Clothing made of fabric plays a regulating role in the process of energy exchange through heat transfer. A set of objective indicat...
