SU1514328A1 - Method of determining composition of yarn and threads for clothes - Google Patents

Description

The invention relates to the textile industry and allows you to determine the composition of yarn with an optimal set of physical, hygienic and toxicological parameters. The method includes pre-fabrication of samples of fabrics from yarn of different mixture composition of natural and synthetic fibers, the execution of clothing from the obtained fabrics and conducting field tests on humans. In the process of testing, the physiological parameters of the tissues are determined, the samples with the optimum comfort parameters are identified, and the mixture with the mill yarn is determined on their basis. 1 tab.

The invention relates to the text of the industrial industry and allows you to choose the mixed composition of yarn for clothing.

The purpose of the invention is the determination of the composition of the yarn with an optimal set of physical, hygienic and toxicological parameters.

Example. Hygienic assessment was performed using sanitary-toxicological studies and experimental socks for tissue samples from different mixture composition of natural and synthetic fibers' with the preliminary manufacture of clothing and full-scale tests on humans. At the same time, the boundary physical parameters for various layers of clothing (hygroscopicity, water content, electrostatic field strength, thermal resistance, breathability, antimicrobial activity and other expansion properties) were determined, and the required content of natural fibers in a mixture with synthetic materials was determined by solving the regression equation = (χ)

The boundary physical parameters for the Rn.1N '| us / clothes clothes are as follows.

For the 1st layer of clothing (underwear, sportswear): hygroscopicity 4 4.5%, body of water (maximum) 2.0 g, tense p> electrostatic field 300 V / cm, thermal resistance 0.07 0.09 kcal / m ² h

Claim The method of determining the composition of yarn and thread for clothing, including the determination of the parameters of natural and synthetic fibers that are part of the yarn, is different - ¹ Topics. what. In order to obtain a yarn composition with an optimal physiconp and toxicological parameters complex, fabric samples are prefabricated from yarn of different, mixed composition 20 from natural and synthetic fibers, clothes are made from the obtained tissues and natural tests are performed on a person. after which they reveal figuratively with optimal parameters of comfort and on their basis determine mixed yarn composition.
