Application of Low Temperature Setting Spandex in the Development of Knitted Products
Using low temperature setting spandex and conventional spandex,polyester and spandex single sided fabric and polyamide and spandex double sided fabric were developed,the dyeing properties were studied,and the trial production was carried out.The results show that the dyeing depth of the low temperature spandex fabric is better,especially the dyeing brightness of the polyamide and spandex fabric is improved.The quality of the fabric produced in the trial test is good,and the defects caused by spandex were not found,and the color fastness,elastic elongation,recovery performance and shrinkage of the low-temperature set spandex are very close to that of the conventional spandex fabric,indicating that the predetermined shape effect can also be achieved after the setting temperature is reduced.This makes it widely used in the preforming of mixed fabric with polyamide,modified polyester and protein fiber.
