Description

Technical Field

[0001] The invention belongs to the field of textile testing equipment, in particular to a textile continuous cool feeling testing equipment based on an infrared thermal imager. Background Art

[0002] The summer climate is hot, and people are in urgent need of a cool experience, especially the demand for clothing that can provide a continuous cool feeling is becoming increasingly strong; however, there is still a lack of relevant instruments and equipment on the market that can effectively test the continuous cool feeling of textiles.

[0003] In the prior art, cool clothing is divided into instant coolness and continuous coolness; the judgment basis is:

[0004] According to the national standard test method GB / T35263-2017 "Testing and evaluating the instantaneous coolness of textiles", the instantaneous coolness refers to the coolness felt by people when the skin and fabric come into contact, which causes the rapid loss of heat on the skin surface; and when the fabric is close to the temperature of the human body, this coolness disappears;

[0005] According to the group standard T / CNGA23-2021 "Testing and Evaluation of the Continuous Cooling Performance of Clothing", continuous cooling on contact means that after the textile comes into contact with the skin and absorbs moisture, the temperature of the textile and the surface drops, making the human body feel continuously cool; this means that the human body must be in a state of sweating in order for the fabric to dissipate heat by evaporation of moisture. When wearing clothes in daily life, it is too late to have a cooling effect until the human body sweats. The human body has already felt uncomfortable, and the continuous loss of heat after sweating may cause the human body to catch cold, and then cause disease. Therefore, this testing and evaluation method is not perfect or has shortcomings.

[0006] In addition, in summer, the human body feels hot, but most of the time it is not hot enough to sweat, and sometimes only parts of the body are very hot. These real-life scenarios cannot effectively determine the continuous cooling performance of textiles based on the group standard T / CNGA23-2021; Summary of the invention

[0007] In view of the above problems, the present invention discloses a textile continuous coolness testing device based on an infrared thermal imager, which is specially used for the continuous coolness testing of fabrics. It can test the fabric's real ability to make people feel cool, thereby facilitating people to objectively analyze, test and evaluate it, and help popularize and promote continuous coolness fabrics, benefiting the majority of consumers. It is especially suitable for third-party testing agencies and university laboratories, and the equipment is very practical.

[0008] The technical solution for achieving the purpose of the present invention is: a textile continuous coolness testing device based on an infrared thermal imager, comprising: an environmental chamber, a test chamber, a transmission assembly, a control simulation platform and a protective cover; the environmental chamber is used to simulate the spatial environment between the clothes and the environmental chamber when the clothes are worn on a person; the test chamber is used to simulate the environment between the human body and the clothes when the clothes are worn on a person; the transmission assembly is used to drive the environmental chamber and the test chamber to move, thereby achieving the clamping and relaxation of the fabric; the protective cover covers the outside of the environmental chamber and the test chamber to provide a closed test environment.

[0009] Compared with the prior art, the present invention has the following significant advantages: the present invention simulates real human skin and an adjustable external temperature and humidity environment, and then uses an infrared thermal imager to detect the cooling ability of the fabric in real time, overcoming the problem that the traditional testing and evaluation methods are not objective and comprehensive. The testing process can not only reflect the thermal conductivity of the material itself, but also incorporate the heat dissipation ability of the material in the process of moisture absorption and quick drying into the cooling test and evaluation. On the whole, this method can objectively characterize the continuous cooling performance of the material at this stage. BRIEF DESCRIPTION OF THE DRAWINGS

The fabric needs to be preheated to the test temperature in the oven before the test, and the test surface is sprayed with a pressure-driven spray bottle. During the test, the sample is loaded into the equipment so that the copper bar contacts the tested fabric on the test surface. The copper bar is set with a certain density, and the infrared thermal imager is used to collect the surface temperature of the fabric. After a suitable period of time, the average continuous temperature difference of the test is obtained, and the continuous cooling ability of the tested fabric is determined by this.
