The importance of breathability of down garment fabrics

2019-05-09

At present, the current situation of testing the air permeability of down clothing fabric is very urgent. GB/ t14272-2002 "down clothing standard" mentions in the lining requirements that "no airtight film is allowed".It has been observed that at present, few manufacturers use "thin film" in the production process of down garment, but many enterprises use coated fabric as the fabric in direct contact with down.Traditional down production and processing, and down direct contact with the fabric is generally the use of high density poplin cloth, anti-drill down effect is very good, and better air permeability.Because the high density poplin cloth price is higher, the general production enterprise has changed to the coating fabric, thus saves the cost.However, coated fabrics used by some manufacturers have poor air permeability, which is almost the same as that of thin films, or even no air permeability at all, which is obviously against the original intention of the standard.In GB/T14272 -- 2002, it was mentioned that "the testing method of the air permeability of finished fabrics should be in accordance with the provisions of GB/T5453 -- 1997", and only the testing standard of air permeability was given, but no specific assessment index was given.The technical guide for export commodities: down garment also does not mention the direct assessment of the breathability of down garment fabric, which indicates that the breathability of down garment fabric is not taken as a necessary assessment index in domestic and foreign standard systems and international trade.However, considering the sanitary problems of down clothing during taking, it is suggested that the down clothing fabric must have some air permeability to prevent the down clothing from breeding and breeding bacteria in a warm and humid environment, thus affecting the health of the wearer.

The importance of breathability of down garment fabrics

Analysis of the breathability test of down clothing fabrics under the general room temperature environment (no sweat), 97% of the total heat loss of the human body is lost by radiation, conduction, convection and skin evaporation, and the other 3% is lost by breathing, defecation and other physiological processes.As a package of human body, clothing radiates heat to human body mainly through conduction and convection, while down garment plays a role of keeping warm mainly by limiting this activity.The coefficient of thermal conductivity of stationary air is much smaller than that of any textile materials. There is a large amount of air in the down jacket, and it is relatively static, which greatly improves its heat insulation value, reduces the exchange of body heat and natural environment, and makes it play an obvious role in keeping warm.As the fabric in direct contact with down requires a certain anti-drilling performance, and this performance is obviously a pair of mutual restriction indexes with the breathability of the fabric, so the breathability of down clothing fabric cannot be compared with the breathability assessment of the above underwear standards.

For down clothing fabrics, should have a certain air permeability, in order to meet the needs of taking.According to the requirements of GB/ t5453-1997, the pressure drop of the Air permeability tester is selected as 200Pa, and the evaluation index is above 10mm/s, which can be evaluated as having breathability.
