Problems solved by technology

The high dyeing temperature of polyester will damage nylon, and it will also damage the spandex of plain weave fabrics commonly used with spandex, resulting in poor hand feeling and poor elasticity.
The moisture-absorbing and quick-drying function is finished with moisture-absorbing and quick-drying additives, which has poor durability and will gradually decrease due to washing.

Embodiment 1

[0019] A kind of nylon polyester composite yarn, adopt 50D / 72F low-temperature cationic dyeable, modified polyester low elastic yarn with special-shaped cross section and 40D / 36F special-shaped cross-section nylon high elastic yarn network to obtain 90D / 108F polyester nylon composite yarn.

[0020] The cross-section of the modified polyester low-elastic yarn is Y-shaped, and the cross-section of the nylon high-elastic yarn is five-lobed.

[0021] The network refers to 80-90 twists / meter.

[0022] A kind of dyeing and finishing process of spandex plain weave cloth of nylon polyester composite yarn, the polyester nylon composite yarn of 90D / 108F is plated with 30D spandex and weaved on a 32G / 32 inch single-jersey machine, and then the dyeing and finishing process is characterized in that: Including the following steps:

[0023] 1) Open-width washing: send the opened gray cloth into the open-width washing machine with low tension for washing, add 5% soda ash, 2% degreasing agent...

Abstract

The invention discloses nylon and polyester composite filaments. 50D / 72F modified polyester low-elasticity filaments which can be dyed by positive ions at low temperature and have deformed sections and 40D / 36F nylon high-elasticity network coalesced filaments with deformed sections are processed to obtain the 90D / 108F nylon and polyester composite filaments. The nylon and polyester composite filaments are formed by processing the polyester low-elasticity filaments which can be dyed by positive ions at low temperature and have deformed sections and nylon high-elasticity network coalesced filaments with deformed sections, can be dyed at the low temperature without affecting handfeel and elasticity of nylon and spandex plain cloth and are not prone to wrinkles or creases, and fiber with deformed sections is high in hydroscopic and fast dry performance, washable, durable, special in luster, smooth in cloth face and high in elasticity and has the obvious bi-color effect and soft handfeel.

Description

technical field [0001] The invention belongs to the field of textile fabrics, in particular to a dyeing and finishing process of nylon polyester composite yarn and spandex plain weave. Background technique [0002] Existing nylon-polyester composite yarns are mostly made of ordinary round-section polyester and round-section nylon network parallel threads, and the two-color gray effect can be obtained by single-dying nylon blank or double-dyeing polyester and nylon. The high dyeing temperature of polyester will damage nylon, and also damage the spandex of the commonly used plain weave cloth with spandex, resulting in poor hand feeling and poor elasticity. The moisture-absorbing and quick-drying function is finished with moisture-absorbing and quick-drying additives, which has poor durability and will gradually decrease due to washing. Contents of the invention [0003] The object of the present invention is to provide a low-elastic polyester yarn and nylon high-elastic yar...
