Problems solved by technology

The existing twisted yarn-dyed fabric can be directly shaped, but after the polyester is twisted, the hand feel is rough and hard, and there is no cotton feeling.
Desizing is required after sizing. The poor color fastness of polyester colored yarn is a world-class problem. The main difficulty in sizing and desizing polyester colored yarn lies in the completeness of desizing and color protection. The existing desizing process such as open width washing Desizing is a protective desizing, and desizing is endless, so the yarn-dyed fabric has no cotton feel, and there has been no good solution for the desizing process on yarn-dyed fabrics

Embodiment approach

[0058] According to one embodiment of the present application, the manufacture method of polyester imitation cotton yarn-dyed fabric comprises the following steps:

[0059] 1) interweaving the provided weft yarn and the warp yarn of sizing to obtain a coarse yarn-dyed fabric, the warp yarn comprising: the core-spun yarn of the dyed polyester yarn as the covering layer and the low-temperature spandex as the core yarn, and the size of the sizing comprises Acrylic paste;

[0060] 2) The first desizing: the coarse yarn-dyed fabric is desized continuously through the desizing mixture I, the temperature of the first desizing is 91-91.5°C and the time is not more than 20min, and the desizing mixture I includes 2-3wt% strong Alkali and 2-3wt% desizing agent;

[0061] 3) Pre-forming: Pre-forming temperature is 180-200°C;

[0062] 4) The second desizing: intermittent desizing through the desizing mixture II, the temperature of the second desizing is 60-90°C and the time is not more th...

Embodiment 1

[0064] Embodiment 1 Yarn-dyed fabric 1#

[0065] 1) A. Provide raw materials: provide polyester and low-temperature spandex with a weight ratio of 13.5:1. The polyester is 75D / 72F matte polyester DTY, and the low-temperature spandex is a new type of low-temperature spandex with a fineness of 30D;

[0066] B. Dyeing of polyester: Dyeing polyester with DyStar’s high-temperature-resistant, water-resistant, and alkali-resistant disperse dyes, the dyeing temperature is 130°C, and the dyeing time for polyester is 40 minutes;

[0067] C. Preparation of warp and weft yarns: dyed polyester is used as the covering layer and low-temperature spandex is used as the core yarn to produce the core-spun yarn by machine wrapping process, with a twist of 5-6 twists / cm and a ratio of 3;

[0068] D, warp yarn sizing: use acrylic size, the size concentration is 12wt%, 130 ℃ to core-spun yarn sizing, for slitting machine warping, make weaving shaft, weaving shaft is reversed shaft sizing, sizing spe...

Embodiment 2

[0075] Embodiment 2 Yarn-dyed fabric 2#, 3#

[0076] Make yarn-dyed fabric 2#, 3# according to the method for embodiment 1, and difference with embodiment 1 is that the weight ratio of the polyester that warp yarn uses and low-temperature spandex is 3,52 to make yarn-dyed fabric 2#, 3# respectively, Yarn-dyed fabric 2# has extremely poor hand feeling elasticity and poor strength; yarn-dyed fabric 3# has a hard hand feel, poor hygroscopicity, and poor cotton feel.

Abstract

The application discloses a polyester imitation cotton yarn-dyed fabric, a manufacturing method and application thereof, belonging to the technical field of textiles. The polyester imitation cotton yarn-dyed fabric is formed by interweaving warp yarns and weft yarns. The warp yarns use dyed polyester as the covering layer and low-temperature spandex as the core-spun yarn of the core yarn, and the weight ratio of the polyester and low-temperature spandex is 4- 49:1, the polyester is treated with alkali weight reduction to form an erosion surface. The polyester-like cotton-dyed fabric has good cotton feeling, high elasticity, high color fastness and low ironing shrinkage, and the yarn-dyed fabric is suitable for the production of high-quality garments, especially for the production of shirts. The manufacturing method of the yarn-dyed fabric saves energy and reduces emission, and the novel polyester yarn-dyed fabric with low ironing shrinkage, high color fastness and cotton-like feel is prepared. The use of the yarn-dyed fabric in the manufacture of garments such as shirts increases its selectivity and functionality.

Description

technical field [0001] The application relates to a polyester imitation cotton yarn-dyed fabric, its manufacturing method and application, and belongs to the field of textile technology. Background technique [0002] Yarn-dyed weaving is a process of weaving fabrics after dyeing yarns or filaments. There are full-colored weaving and half-dyed yarns. It refers to the process of dyeing yarns or filaments first, and then using colored yarns for weaving. Method, this kind of fabric is called "yarn-dyed fabric". Yarn-dyed fabrics are dyed first, then weaved, and finally finished. Piece dyeing is to put the original color gray fabrics into the dyeing tank for jig dyeing (or long car pad dyeing), and then finish the finishing. The use of woven cotton-like polyester in piece dyeing is relatively mature, and there is no precedent for yarn-dyed weaving. [0003] Woven polyester yarn-dyed fabrics are divided into twisting and sizing from the weaving process. The twisting and sizing a...
