Research of change of fabric properties in the process operation
The article discusses the study of changes in the properties of linen fabrics during operation. It is established that one of the main indicators when choosing medical clothing is tissue shrinkage. Despite the advantages of linen fabrics (anti-septic properties, ability to withstand harmful microorganisms, etc.), medical workers are skeptical about linen. Many are repelled by the significant creasing of tissues, as well as shrinkage after washing and use. Among the advantages of linen fabrics can be distinguished: high strength, ability to quickly wash, good hygroscopicity and moisture absorption capacity. The aim of the work was to study the behavior of linen and half-linen fabrics for medical purposes after wet treatments and the kinetics of their wear. As research objects, 10 samples of linen and half-linen fabrics of Russian production were selected. The study also conducted a gradual deterioration of the properties of linen fabrics as a result of washing. As a criterion for the gradual deterioration of the properties of linen fabrics as a result of washing, in this work, a change in abrasion resistance was chosen. The research results established that in all samples of linen and half-linen fabrics there is a rapid decrease in the values of abrasion resistance in the range from 1 to 5 washings. Compared with the values of this indicator for 0 washing, a deterioration of 1.02-4.59 times is observed for all samples.
