What is the difference between twisted and untwisted polypropylene fiber?
Untwisted polypropylene twisted yarn can be seen at a glance. Twisting is to add the appropriate twist to the stretched whisk, so that the whisk fibers hug and twist each other, so that it has a certain strength, elasticity and luster.
Benefits of polypropylene twist yarn after twisting:
(1) Increase the strength and friction resistance of the silk thread to reduce fuzz and breakage and improve the fastness of the silk fabric.
(2) Make the silk thread have a certain shape and color, give the appearance of the fabric with refraction, crepe or wool, knot and other effects.
(3) Increase the elasticity of the silk thread, improve the wrinkle resistance of the fabric (imitation memory ironing fabric) and air permeability (strong twist fabric), and make the fabric cool and comfortable.
Of course, the following points need to be noted in the production of polypropylene twisted yarn:
(1) There are two kinds of twisting methods: dry twisting and wet twisting. Conventional twisting uses dry twisting, but for some multi-strand silkworm silk, wet twisting must be used to meet the process requirements.
(2) Dry twist processing adopts ordinary twisting machine and double twisting machine, while wet twist processing adopts wet twisting machine.
(3) To make the surface of the yarn with feather, knot and other fancy effect, must use a fancy twisting machine.
(4) When the yarn is retwisted, the twist used is generally opposite to the initial twist.
(5) Whether the raw material of warp and weft wire needs to be twisted, why to twist, what twist direction to add, and how much twist to add, should be set according to the requirements of the fabric specifications. In addition to the fancy twisting machine, other twisting processes require good winding shape, easy to decompress, uniform tension, appropriate size, uniform twist, steam shaping does not roll. Under the premise of meeting the technological requirements, the winding should be increased appropriately to improve the output and quality of twisting wire processing.
