Embodiment 1

[0035] Example 1: Pure mulberry silk denim and its preparation process.

[0036] The denim silk in this embodiment uses 100% mulberry silk as the warp and weft, the warp is 75.4Tex blue silk, the weft is 75.4Tex natural silk, and the twist is 450±20 twists / m. The warp density is 26.8 pieces / cm, the weft density is 13.2 pieces / cm, and the square meter weight is 327.7g / m 2 . The above-mentioned warp and weft are obtained from silk noil through wool spinning (wool spinning and worst spinning), grooved drum, spinning, twisting and other processes.

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

[0038] (1) Warp silk bulking: According to the bath ratio of 1:25, under the condition of 85 ℃, the warp silk is added to the bulking agent and bulked for 50 minutes; wherein: the bulking agent is an aqueous solution of 1.2% softener SCM (in weight percent). count);

[0039] (2) Washing: Rinse the expanded warp silk with pure water until th...

Embodiment 2

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

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

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

[0051] (1) Warp silk bulking: According to the bath ratio of 1:20, under the condition of 80 ° C, the warp silk is added to the bulking agent and bulked for 45 minutes; wherein: the bulking agent is an aqueous solution of 1.5% softene...

Embodiment 3

[0061] Example 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 enzymatic finishing), which discloses silk denim socks and the preparation method thereof, the denim silk finished with mixed neutral protease in Example 1 of the present invention has different characteristics. The performance of each item has been improved, and the specific data are shown in Table 1 and Table 2.

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

[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 silk of the present invention is greatly reduced compared with that before the enzyme treatment, and the effect is better than that of the denim socks treated with alkaline protease, so that the...

Abstract

The invention discloses a mulberry silk denim and a preparation method thereof. Specifically, the method first carries out warp puffing, the puffed warp is washed and then dyed with a weak acid dye and fixed with a color-fixing agent, then the dyed warp and natural weft are woven into denim gray silk, and finally mixed After washing with neutral protease and softening with silicone softener, washing and drying can obtain the mulberry silk denim of the present invention. The present invention adopts a unique post-treatment method, effectively overcomes the problem in the prior art that the strength of silk denim is greatly reduced after using alkaline protease on the premise of ensuring the comfort of wearing, and makes the denim in the enzymatic washing process It can withstand higher temperature and longer time, further improves the effect of enzyme washing, and bidirectionally optimizes the wearing fastness and softness of finished denim.

Description

technical field [0001] The invention belongs to the technical field of textile production, in particular to a mulberry silk denim silk and a preparation method thereof. Background technique [0002] Denim (also known as denim, English name Denim) is a yarn-dyed warp twill cotton fabric with dark warp yarns and light weft yarns. Denim has been popular for more than 100 years because of its unique charm, rough and bold charm and comfortable and convenient wearing effect, and it is favored by people from all walks of life. However, the existing denim fabrics are generally made of cotton or blended with cotton and chemical fibers. Although the fabrics are thick and tight, 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 real silk denim, which uses 100% mulberry silk and more than 60% mulberry silk and other fibers blended to make warp ...
