Embodiment 1

[0035] Embodiment 1: pure mulberry silk denim and its preparation process.

[0036] The denim in the present embodiment adopts 100% mulberry silk as the warp and weft, the warp is the blue silk of 75.4Tex, the weft is the natural color silk of 75.4Tex, and the twist is 450 ± 20 twists / m. The warp density is 26.8 threads / cm, the weft density is 13.2 threads / cm, and the square meter weight is 327.7g / m 2 . The above-mentioned warp and weft are obtained from silk noil through processes such as wool spinning (slubbing and worsted spinning), groove drum, shaking yarn, and twisting.

[0037] The preparation method of above-mentioned denim comprises the following steps:

[0038] (1) Warp yarn puffing: According to the bath ratio of 1:25, under the condition of 85°C, add the warp yarn to the puffing agent for 50 minutes; wherein: the puffing agent is 1.2% aqueous solution of softener SCM (by weight percentage count);

[0039] (2) Washing: Rinse the puffed warp yarn with pure water ...

Embodiment 2

[0048] Embodiment 2: Blended mulberry silk denim and its preparation process.

[0049] The denim in this embodiment adopts 100% mulberry silk as the warp yarn, adopts 70% mulberry silk and 30% nylon yarn blending as the weft yarn, and the warp yarn is a blue silk of 75.4Tex, and the twist is 450± 20 twists / m, warp density 26.8 threads / cm, weft 78.6Tex natural color blended yarn, twist 510±20 twists / m, weft density 13.2 threads / cm, square meter weight 348.2g / m 2 . The above-mentioned warp and weft are obtained from silk noil through processes such as wool spinning (slubbing and worsted spinning), groove drum, shaking yarn, blending, and twisting.

[0050] The preparation method of above-mentioned denim comprises the following steps:

[0051] (1) Warp yarn puffing: according to the bath ratio of 1:20, under the condition of 80°C, add the warp yarn to the puffing agent for 45 minutes; wherein: the puffing agent is an aqueous solution of 1.5% softener SCM (by weight percentage ...

Embodiment 3

[0061] Embodiment 3: Performance test of mulberry silk denim.

[0062] Compared with the prior art (Chinese patent application CN102444024A, in which alkaline protease 2709 is used for biological enzyme finishing) disclosing silk denim stockings and their preparation method, each of the denim finished with mixed neutral protease in Example 1 of the present invention The performance of each item has been improved, and the specific data are shown in Table 1 and Table 2.

[0063] Table 1. Changes in drape coefficient and friction coefficient of mulberry silk denim before and after enzyme treatment:

[0064] .

[0065] As can be seen from the above table, through the treatment of mixed neutral protease, the drape coefficient of the mulberry silk denim of the present invention is greatly reduced compared with that before the enzyme treatment, and the effect is better than that of denim socks treated with alkaline protease, making the denim of the present invention more soft. I...

Abstract

The invention discloses mulberry silk noil yarn type cowboy silk and a preparation method thereof. The method comprises the following concrete steps: firstly, expanding warp silk, washing the expanded warp silk, dyeing with a weak acid dye, and fixing the color by a color fixing agent; secondly, weaving the dyed warp silk and undyed weft silk into a cowboy silk blank; finally, performing enzyme wash by mixed neutral protease, performing soft finish by an organic silicon softener, washing, and drying to obtain the mulberry silk noil yarn type cowboy silk. According to the method, a unique post-treatment process is adopted, the problem that the strength of cowboy silk treated with alkaline protease is greatly reduced in the prior art is effectively solved on the premise of guaranteeing the wearing comfort, the cowboy silk can be tolerant to relatively high temperature and relatively long time in the enzyme wash process, the enzyme wash effect is further improved, and the wearing fastness and softness of the finished cowboy silk are bidirectionally optimized.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to a mulberry silk denim and a preparation method thereof. Background technique [0002] Denim (also known as denim, English name Denim) is a kind of yarn-dyed warp-faced twill cotton fabric, with dark warp yarns and light weft yarns. Because of its unique style, rough and bold charm and comfortable and convenient wearing effect, denim has been sold for more than 100 years and is still popular, and is favored by people from all walks of life. However, the existing denim fabrics are generally made of cotton or cotton and chemical fiber blends. Although the fabrics are thick and compact, they are slightly rough and feel hard. [0003] In order to make denim clothing more comfortable to wear and look more noble, Chinese invention patent application CN1056322A discloses a kind of silk denim, using 100% mulberry silk and more than 60% mulberry silk blended with ot...
