Reasons for the size change of Non-Sterile Protective Coveralls products after repeated cleaning and drying
Non-Sterile Protective Coveralls refers to the protective clothing used by medical staff and people entering specific medical and health areas, which can prevent germs and harmful substances. Non-Sterile Protective Coveralls can be used in areas outside the non-intensive care unit. Protective isolation. The clothing material is generally a synthetic polyester fabric with conductive yarns inlaid.
The most important part of the management of Non-Sterile Protective Coveralls is cleaning. Although the fiber itself is a polyester fiber that is difficult to stain, how to maintain it is an important factor, that is, the method of cleaning. If ordinary washing method is used, of course it will be soiled on the contrary. Therefore, a special method must be used. Non-Sterile Protective Coveralls is considered from the management perspective, and must be cleaned in a clean room when cleaning.
One of the main reasons for the shrinkage of Non-Sterile Protective Coveralls is formed during the fabric production process. In the process of spinning, weaving, printing and dyeing, the fibers and spinning threads of the fabric are subjected to a series of mechanical stretching and compression, resulting in deformation. These deformations are relatively stable in the dry state, but during the washing process, the fibers and yarns are subjected to moisture and heat, and the fibers will expand from the warp direction (the direction perpendicular to the fibers), that is, the fibers will become thicker. But its length is shortened instead. Therefore, this kind of fabric becomes thicker and harder when immersed, and shrinks obviously after drying.
Different types of fabric fibers have different degrees of shrinkage. Generally, man-made fibers have the largest shrinkage. For example, the shrinkage rate of viscose fiber (rayon) can reach 10%, and the shrinkage rate of cotton and linen fabrics is usually 3%~5%, while the shrinkage rate of polyester and polypropylene fabrics is only 0.5%~1 %. It can be seen that the shrinkage of synthetic fibers is much less than that of hydrophilic fiber fabrics. Non-Sterile Protective Coveralls uses high-quality polyester fiber, and the shrinkage rate is quite low compared with other fabrics (cotton, linen, man-made fibers).
