Problems solved by technology

There are three disadvantages in this product and its preparation method: (1) it does not have the silky characteristics of silk filament fabric; (2) it needs to be spun, which increases the cost; (3) because the silk is thin and the surface is extremely smooth, During the production process, it is easy to slip, the loss rate is large, and the waste is serious, which greatly increases the production cost
These above-mentioned patents all do not relate to the interweaving fabric that adopts silk filament raw silk and wool fiber yarn

Embodiment 1

[0021] Using 22D / 2 undegummed raw silk as the warp yarn, 56s single yarn spun from 90s mercerized preshrunk wool as the weft yarn, weaving with 5 pieces of satin weave, the gray fabric has a warp density of 110 strands / cm and a weft density of 38 strands / cm cm, gray cloth width 296cm, to obtain gray cloth. Singeing the gray cloth first, then pretreating the gray cloth on the open-width refiner, degumming, and finishing in one bath. In the water bath, S114 neutral protease is used as the degumming agent, the pH is 6-6.4, the temperature is 35°C, Bath ratio 40:1, treatment time 7h, use aziridine crosslinking agent XR-100 (polyurethane) as crosslinking agent; further replace with 85℃ water, adjust pH to 5 with acetic acid, boil for 15min; Pre-shrunk under tension to obtain a grammage of 110g / m 2 , wool 65%, silk 35% high-grade silk wool fabrics, used for shirts, bed sheets, quilts and other fabrics.

Embodiment 2

[0023] 40s single yarn spun from 70s Merino mercerized shrink-proof wool is used as warp yarn, 22D / 2 undegummed raw silk is used as weft yarn, and 3 / 1, 1 / 3 twill weave is used for weaving. Density 38 / cm, fabric width 290cm. On the open-width refining machine, the gray cloth is pretreated, degummed, and finished in one bath. In the water bath, use 3g / L papain as the degumming agent, adjust the pH to 6, the temperature is 45°C, the bath ratio is 50:1, the treatment time is 5h, and the divinyl sulfone crosslinking agent is used; ℃ water, adjust the pH to 6.5 with acetic acid, and boil for 15 minutes. Obtain a gram weight of 90g / m 2 . 60% wool, 30% silk, and 10% nylon are light and thin silk-wool fabrics, with yarn-dyed yarn structure and three-dimensional jacquard weave to highlight the fashion and high-end of silk and wool fibers. Used for women's high-end suits, high-end curtains, quilt covers and other fabrics.

Embodiment 3

[0025] Using 22D / 1 undegummed raw silk as warp yarn, 70s mercerized preshrunk wool 80% mercerized wool and hemp 20% blended 40s single yarn as weft yarn, and 5 pieces of satin weave for double layer weaving, The warp density of the gray cloth is 85 threads / cm, the weft density is 48 threads / cm, and the width of the gray cloth is 292cm. Singeing is performed on the gray cloth first, and then the gray cloth is pretreated, degummed, and degummed in one bath on the open-width refiner. In the water bath, S114 neutral protease is used as the degumming agent, the pH is 7-7.5, and the temperature is 50°C. The bath ratio is 30:1, the treatment time is 8 hours, and the organic silicon coupling agent KGS-2012 is used as the cross-linking agent; after fully rinsing, it is further replaced with 85°C water, and the pH is adjusted to 6.5 with acetic acid, and it is boiled for 20 minutes. Pre-shrunk under low tension to obtain a grammage of 150g / m 2 , 65% wool, 15% linen, 20% silk wool doubl...

Abstract

The invention relates to a silk-wool fabric, which is characterized in that: it has a different-plane structure, undegummed raw silk and wool yarn are respectively used as warp yarns or weft yarns to interweave gray fabrics, and the gray fabrics are sequentially singed → pretreated, degummed, and degummed. Bath Finishing → Obtained after pre-shrinking. In the silk-wool fabric with different texture structure of the present invention, one side of the fabric is mainly composed of silk filaments, which has the silkiness, softness and luster of silk fabrics; the other side of the fabric is mainly composed of wool fibers, which has the elasticity and warmth of wool fabrics properties and good dimensional stability. The degumming process of silk and the degumming process of wool are completed in one bath on the open-width scouring machine for silk weaving. It can be directly woven into gray cloth with raw silk and wool as raw materials, and then degummed and degummed, which significantly shortens the process flow. Moreover, the slippage of silk in the silk-wool blending process is avoided, the cost is greatly saved, and the characteristics of silk fabrics and wool fabrics are fully reflected.

Description

technical field [0001] The invention relates to a silk wool fabric and a preparation method thereof, in particular to a fabric interwoven with undegummed raw silk and wool fibers and a corresponding preparation method. Background technique [0002] Mulberry silk and wool are precious animal fibers and high-grade natural fibers in textile materials. Silk is soft, luxurious in luster, good in body-fitting comfort, moisture-absorbing and breathable, and light, but has poor elasticity, poor wrinkle resistance, and is prone to yellowing in the sun. Wool fiber is naturally curled, has good elasticity, and has high moisture regain and good hygroscopicity, and its fabric has a warm feeling on contact. Therefore, if silk and wool are woven into a fabric in a certain way, a fabric that has both the luster and skin-friendly properties of silk and the elasticity and warmth of wool can be obtained, which will be a very high-grade pure natural animal fiber fabric. Silk wool fabric has a...
