Chemical route to polyurethane polymer Employed in manufacture of spandex. Spandex is principally composed of a polyurea derived within the reaction of the diol plus a diisocyanate. Two lessons of spandex are outlined from the "macrodiols". A person class of macrodiols may be the oligomer produced from tetrahydrofuran (i.
In case you read “latex free of charge” on the textile garment, this commonly suggests there's no organic latex rubber while in the product or service and spandex is definitely the replacement for the rubber.
We've been in compliance with the necessities of COPPA (Childrens On the internet Privacy Security Act), we don't gather any information from everyone beneath 13 decades of age.

You may get to this web site from most pages on the positioning – only click the ‘My specifics’ backlink at the best from the screen if you find yourself signed in.
Mechanical covered yarn is produced by repeatedly twisting and winding the out filaments about a uniformly drafted Main spandex yarn. It really is twisted and twists are calculated in "TPM" (twist for each meter). The fabric type is flat is its primary aspect.
Spandex covered yarn, also known as lycra spandex yarn or elastic covered yarn, is a unique type of textile materials that combines the elasticity of spandex yarn (generally known as elastane or Lycra) with the strength and texture of other core yarn elements( 100% polyester or one hundred% nylon).
Derun create ACY from POY and spandex straight. Our equipment can perform attract texturing and air covering in one stage, give a greater yarn evenness and strength.
Herng Fa's process is especially noteworthy for its versatility, given that the matching yarn and The 2 principal yarns can be altered In line with certain customer necessities.
Pre-polymer is then reacted further more, in a variety of ways, and drawn read more out to provide an extended fiber. The most commonly utilized approach is the solution dry spinning that creates more than ninety% of the world’s spandex fibers.
Herng Fa's Sophisticated engineering enables us to personalize the principle and matching yarns In line with your distinct necessities, guaranteeing a customized Remedy to your textile wants.
ACY brings together filaments with a sequential compressed air jet and addresses the interior elastic with air dots. SCY and DCY are produced by mechanically wrapping the elastic core with one or two outer filaments.
It maximizes the Main yarn's elasticity even though preserving the qualities from the outer fiber. Covered Yarn is greatly Utilized in applications for instance hosiery, textiles, and health-related materials. Widespread types consist of solitary-covered yarn and double-covered yarn.
