Embodiment 1
[0030] This example provides a method for preparing a non-deformable all-cotton fabric after multiple washings. The preparation method is used to prepare a piece-dyed fabric that is washable and does not shrink.
[0031] Such as figure 1 As shown, the preparation method of the present embodiment mainly includes the following steps:
[0032] S101: Weaving;
[0033] Select 32G double-sided machine to weave cotton fiber into double-sided cloth (grey cloth), and the weight of fabric is 170-180g / m2.
[0034] The cotton fiber is 100% PIMA cotton (first-grade cotton), the length of cotton fiber is 37mm, 60S / 1 yarn, combed and compact spun; the evenness CV of cotton fiber≤11.8%, details (-50%)≤1, thick places (+50%) ≤ 8, neps (+140%) ≤ 120, neps (+200%) ≤ 30, single yarn strength ≥ 250CN, single strength CV ≤ 8%, twist 80-110 twist / 10cm, twist CV≤4.5%, moisture regain 5.5-5.8%, where CV means coefficient of variation.

Embodiment 2
[0063] This example provides a method for preparing a non-deformable cotton fabric after repeated washing. The difference from the first example above is that this method is used to prepare floral ash or striped cloth without dyeing.
[0064] Such as figure 2 As shown, the preparation method of the present embodiment comprises the following steps:
[0065] S201: Weaving;
[0066] Select 32G double-sided machine to weave cotton fiber into double-sided cloth (grey cloth), and the weight of fabric is 170-180g / m2.
[0067] The cotton fiber is 100% PIMA cotton (first-grade cotton), the length of cotton fiber is 37mm, 60S / 1 yarn, combed and compact spun; the evenness CV of cotton fiber≤11.8%, details (-50%)≤1, thick place (+50%) ≤ 8, neps (+140%) ≤ 120, neps (+200%) ≤ 30, single yarn strength ≥ 250CN, single strength CV ≤ 8%, twist 80-110 twist / 10cm, twist CV≤4.5%, moisture regain 5.5-5.8%, where CV means coefficient of variation.

Abstract
The invention discloses a non-deformable all-cotton fabric washed multiple times with water and a preparation method thereof. The preparation method comprises the steps of: weaving-singing-boiling-biological enzyme washing-drying cloth shaping-liquid ammonia mercerizing treatment-dyeing or washing ‑Open width drying‑Styling‑Shrinking‑Finished product. Since the preparation method uses dry cloth liquid ammonia mercerizing treatment to improve the elasticity and washability of the fabric, it does not need to use chemical additives such as polyurethane and super-cool elastic agent, which reduces pollution and is more environmentally friendly, and liquid ammonia mercerizing treatment can achieve better hand feeling, Less shrinkage and abrasion-resistant fabric.
Description
technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a non-deformable all-cotton fabric washed multiple times and a preparation method thereof. Background technique [0002] The preparation method of the fabric in the prior art mainly includes the following steps: knitting double-sided fabric - boiling and bleaching - biological enzyme washing - dyeing - oversoftening - dehydration and drying in open width - polyurethane finishing solution treatment - drying - calendering - shaping - pretreatment shrink - finished product. The preparation method in the prior art relies entirely on additives such as chemical additives such as polyurethane and super-cool elastic agent to improve the elasticity and shape retention of the fabric, which is not environmentally friendly and cannot be washed. Contents of the invention [0003] The invention provides a more environmentally friendly and washable all-cotton fabric and a preparation...
