preparation example Construction

[0036] A preparation method of easily degradable differentiated auxiliary materials, comprising the following steps:

[0037] (1) Pretreatment: bleaching long-staple cotton yarn and long-staple cotton fiber to obtain bleached cotton yarn and bleached cotton fiber. The long-staple cotton fibers may be long-staple cotton.

[0038] (2) The first blended yarn is made: the polylactic acid short fiber and the bleached cotton yarn and the bleached cotton fiber obtained in part of step 1 are blended and twisted according to different mass ratios to obtain the first blended spinning ratio and different twist. blended yarn.

[0039] (3) The second blended yarn is made: the polylactic acid fiber and the bleached cotton yarn obtained in part of the first step and the bleached cotton fiber are blended, drawn or twisted and twisted according to different mass ratios to obtain different blending ratios and a second blended yarn with a different twist.

[0040] (4) Differential structure d...

Embodiment 1

[0062] This embodiment provides a preparation method of easily degradable differentiated excipients.

[0063] (1) Pre-treatment: The long-staple cotton yarn produced in Xinjiang of 20s / 2~100s / 2 is used for degreasing, bleaching, dehydration and drying in a relaxed state with a hank dyeing equipment, so that the long-staple cotton yarn is fully retracted to obtain low shrinkage rate of bleached cotton yarn.

[0064] (2) Production of the first blended yarn: the 10-45% bleached cotton yarn obtained in step 1 is blended and twisted with 55-90% polylactic acid short fibers to obtain polylactic acid containing 55%, 60%, 65%, Eight blended 20S / 2-100S / 2 first blended yarns with different contents of 70%, 75%, 80%, 85%, and 90% are spun, and the obtained first blended yarn has a twist of 150-300 twists.

[0065] (3) Production of the second blended yarn: the 5-55% bleached cotton yarn obtained in step 1 is blended with 45-95% polylactic acid fiber, and then drawn and twisted with the...

Embodiment 2

[0105] This embodiment provides a preparation method of easily degradable differentiated excipients.

[0106] The difference between the method of this embodiment and the embodiment 1 is that in step 1, ordinary 20s / 2~100s / 2 cotton yarn will be used for degreasing, bleaching, dehydration, and drying to obtain bleached cotton yarn, and the rest are the same.

[0107] Effect and test:

[0108] The appearance effect and color fastness of the obtained finished fabrics were tested, and the testing methods and standards are shown in Table 3 below.

[0109] table 3

Abstract

The invention discloses a preparation method of an easily degradable differentiated auxiliary material. The method comprises the following steps: (1) pretreatment: bleaching long-staple cotton yarn and long-staple cotton fiber to obtain bleached cotton yarn and bleached cotton fiber; (2) making the first blended yarn: mixing polylactic acid staple fiber with part The bleached cotton yarn and the bleached cotton fiber are blended and twisted according to different mass ratios to obtain the first blended yarns with different blending ratios and different twists; (3) making the second blended yarn: mixing polylactic acid short fibers with the The above-mentioned bleached cotton yarn and the above-mentioned bleached cotton fiber are blended, drawn or parallel-twisted and twisted according to different proportions to obtain the second blended yarn; (4) pattern differential organization design; (5) weaving; (6) pre- shrinkage; (7) dyeing; (8) special-shaped cutting. The auxiliary materials prepared by this method can be degraded and can be eagerly cut. The gray effect, gradual change effect and jacquard effect are easy to change quickly.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a preparation method of easily degradable differentiated auxiliary materials and the auxiliary materials. Background technique [0002] As consumers' demand for clothing differentiation and personalization is getting higher and higher, clothing manufacturers generally achieve consumers' personalized needs through the differentiation and personalization of clothing accessories. Compared with ready-to-wear, the weight of accessories accounts for a small proportion of clothing, coupled with individualized and differentiated needs, resulting in a further reduction in the demand for a single type of accessories, but the production process of these accessories cannot be less, so the production of these differentiated accessories High cost and long cycle. For example, to match the gray accessories of gray ready-to-wear fabrics, it is necessary to dye the fibers first, and then mix and match the...
