ARTICLE ANNOTATION

quote
This article presents the topicality of the problem, the sequence of technological processes in manufacture of silk twisted yarn from raw silk used for making of a medical bandage. In order to fold a few threads, and give them a twist, first raw silk is rewound onto a spool. Before rewinding, hanks are checked for gluing, in our case low gluing is determined, therefore, in order to soften the glued spots, the thread is treated with an emulsion by spraying. Then, the raw silk is kept in the common room and is rewound to the two flange reel using the MT-85 machine according to the Japanese technology. The principle of operation and technological drawings are provided. Torsion is carried out by adding 3 raw silk 2,33 tex to give the left twist S 350 tw/m and adding 8 raw silk 3,23 tex with the left twisting S 500 tw/m. The torsion process is performed on a TK-2 twisting machine. The process of fixing the twist of the finished twisted yarns is implemented using Japanese equipment SC-750. The quality indicators of twisted yarn are as follows: linear density, coefficient of variation in linear density, breaking load, breaking elongation, direction and amount of twist, and coeffiсients of variation in twisting.
