Description

Technical Field

[0001] The invention relates to the technical field of fabric processing, and in particular to a comfortable and easy-to-care-for silk-vinegar-wool composite yarn interlaced fabric and a production process thereof. Background Art

[0002] As we all know, pure silk fabrics are light and elegant, soft to the touch, soft mercerized, and breathable and comfortable to wear. Pure wool fabrics have a strong wooly feel, good drape, and are elastic, and are also breathable and comfortable to wear. Although these two natural protein fibers have excellent properties that other fibers cannot match, their respective application fields have certain limitations. Pure silk is suitable for close-fitting wear, while pure wool is mainly used as outerwear. With the development of the economy and the improvement of people's living standards, people have begun to pursue clothing fabrics that have novelty, comfort, and easy care. Fabrics made of a single fiber material obviously can no longer meet new needs. Then how to combine the excellent properties of two or more fibers to open up new areas of four-season inner and outer fabrics has become a new research direction.

[0003] Silk is composed of sericin and fibroin, and is composed of 18 kinds of amino acids in different proportions and spaces. It is a protein fiber and is known as the "Queen of Fibers". The fabric has an elegant and soft luster, a pearly luster, a soft, smooth, thick, and plump feel, excellent elasticity, a flowing appearance, good moisture absorption and breathability, and a skin care and health care effect. However, silk clothing has poor wrinkle resistance, poor dyeing fastness, and is prone to yellowing and fading in the sun, and is easily moth-eaten.

[0004] Wool is also a protein fiber, it has many excellent properties, such as good elasticity, strong moisture absorption, good warmth retention, not easy to stain, soft luster. But wool fiber also has some shortcomings, because it is a short fiber, so it is easy to pilling, and there are a lot of wool fibers exposed on the surface of wool yarn, when it comes into contact with human skin, there is a fluffy itchy feeling, which makes the skin feel uncomfortable.

[0005] Acetate filaments have a smooth surface, bright color, and soft feel. Among chemical fibers, their performance is closest to that of mulberry silk. Fabrics made of acetate filaments are cool, breathable, silky, comfortable, and have a good natural drape. Due to the inherent physical properties of acetate fibers, the fabric is crisp even in humid weather and looks fresh and neat. The fabric does not easily swell when absorbing water and dries quickly. It does not shrink or deform after contacting water and has good stability. However, the silk-vinegar interwoven fabric needs to be degummed by alkali smelting, and the printed products also need to be steamed and washed, so the fabric strength often does not meet the requirements.

[0006] Therefore, how to overcome the shortcomings of single fiber fabrics such as pure mulberry silk, pure wool fiber, acetate filament, etc., combine the excellent properties of mulberry silk, wool and acetate fiber into new fabrics, and open up new areas of four-season interior and exterior fabrics has become an urgent problem to be solved. Summary of the invention

[0007] The invention provides a silk-vinegar-wool composite yarn interwoven fabric and a production process thereof. Composite silk filament yarns formed by mulberry silk acetate filament composite yarns and wool yarns are interwoven to form the fabric. The fabric embodies the excellent properties of three fiber raw materials, namely, mulberry silk, wool and acetate, and makes up for the shortcomings of mulberry silk being easily wrinkled and wool being itchy. The fabric has the touch and soft luster of real silk fabric, is free of itching, has a comfortable and natural drape, has good dimensional stability, improves the anti-pilling performance of the fabric, and has a certain anti-wrinkle effect. The fabric strength meets the standard requirements of real silk fabric.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A first aspect of the present invention provides a silk-vinegar-wool composite yarn interwoven fabric, wherein the fabric is interwoven with silk-vinegar-wool composite yarns, wherein the silk-vinegar-wool composite yarn is a composite yarn formed by twisting silk-vinegar composite silk and wool yarn in parallel, with wool yarn as the core and silk-vinegar composite silk wrapped in the outer layer, and the silk-vinegar composite silk is a composite filament yarn formed by twisting mulberry silk and acetate filament in parallel.

[0010] The silk-vinegar-wool composite yarn interwoven fabric prepared in the present invention can also be called mulberry silk-acetate-wool interwoven woven fabric. The weave structure of the silk-vinegar-wool interwoven fabric can be a three-primary weave, a complex weave, a jacquard weave, etc.

[0011] Using the above technical solution:

[0012] In the present invention, it is taken into consideration that the crystallinity of silk fibroin in mulberry silk is low and its chemical cross-linking property is relatively poor compared with other fibers, and the wrinkle recovery property of silk fabric is poor in wet state. In order to improve the wrinkle resistance of the fabric, mulberry silk and acetate filament are firstly twisted together to form a composite filament yarn - silk-vinegar composite yarn; in order to solve the problems of pilling and itching caused by wool or cashmere fibers and increase the fluffiness, resilience and comfort of the fabric, the silk-vinegar composite yarn and wool yarn are twisted together to form a composite yarn - silk-vinegar-wool composite yarn with wool yarn as the core and the silk-vinegar composite yarn wrapped in the outer layer; finally, the silk-vinegar-wool composite yarn is interwoven to form the final fabric.

[0013] The silk-vinegar-wool composite yarn interwoven fabric of the present invention embodies the excellent properties of three materials, namely, mulberry silk, wool and acetate fiber, improves the problems that pure silk fabric is easy to stick to the body due to sweating, pure wool fabric has an itchy feeling, and the strength of silk-vinegar woven fabric does not meet the requirements, and the wrinkle resistance of the fabric is improved, and a unique gray-colored fabric can be dyed. Compared with single-component fabrics, the fabric has excellent wearing performance, is comfortable and easy to care for, has the touch and soft luster of silk fabric, has no itchy feeling, has a comfortable and natural drape, has good dimensional stability, improves the anti-pilling performance of the fabric, and has a certain anti-wrinkle effect. The fabric strength meets the standard requirements of silk fabrics, and compared with pure silk and pure wool fabrics of the same gram weight, the fabric cost is reduced, and the market competitiveness of the fabric is improved.

[0014] Preferably, the process of doubling mulberry silk and acetate filaments in the silk-vinegar composite yarn is to doubly one or more mulberry silk filaments with one or more acetate filaments.

[0015] Preferably, the process of paralleling the silk-vinegar composite yarn and the wool yarn in the silk-vinegar-wool composite yarn is to parallel one or more silk-vinegar composite yarns with a wool yarn or cashmere blended yarn.

[0016] A second aspect of the present invention provides a production process for a silk-vinegar-wool composite yarn interwoven fabric, comprising the following steps:

[0017] S1. Front-end preparation:

[0018] The mulberry silk and acetate filament are twisted together to form a silk-vinegar composite silk yarn, and the silk-vinegar composite silk yarn is twisted together with wool yarn to form a silk-vinegar-wool composite yarn with wool yarn as the core and the silk-vinegar composite silk wrapped in the outer layer;

[0019] S2. Weaving:

[0020] Set the warp and weft yarn tension, machine speed, opening time and other parameters according to the fabric type, start weaving, and weave the prepared warp and weft yarns into the designed fabric;

[0021] Warp tension: 120~160cn, speed: 280~330RMP;

[0022] S3, practice the whole step;

[0023] S4, after scouring and dyeing, to obtain the silk-vinegar-wool composite yarn interwoven fabric.

[0024] Furthermore, in step S2, the silk-vinegar-wool composite yarn is used as the weft yarn, and the silk-vinegar composite silk is used as the warp yarn.

[0025] Furthermore, in step S1, the silk-vinegar composite silk yarn and the silk-vinegar-wool composite yarn are twisted 2.5 to 27 times per cm.

[0026] Furthermore, in step S1, the silk-vinegar composite yarn and the silk-vinegar-wool composite yarn are subjected to heat and moisture setting treatment, specifically: steaming for 60 to 90 minutes at 80 to 95°C according to the yarn twist. When the composite yarn is twisted, it is subjected to external force, and rapid elastic deformation, slow elastic deformation and plastic deformation occur at the same time. This step is to solve the problems of untwisting and curling in the production process, and avoid or reduce the strength, elongation and elastic damage of the yarn.

[0027] Furthermore, in step S4, the post-dyeing step is to dye the fabric under the conditions of pH value 3-5, dyeing temperature 60-85°C, dyeing time 30-90min, and heat preservation time 40-80min to form a gray effect. In this step, acid screen printing, reactive screen printing or digital printing is used to dye the fabric with mixed colors and color layers under specific conditions according to the dyeing performance of the fiber.

[0028] Furthermore, in step S3, the smelting step includes pre-treatment of the green dough → enzyme treatment → re-smelting → water washing → drying to obtain a cooked dough, and during the enzyme treatment, a protease is used for degumming at a pH value of 3 to 9.5 and a temperature of 60 to 80° C. After the green dough is refined into a cooked dough, it is easy to obtain a soft feel and a drape.

[0029] Furthermore, the specifications of the mulberry silk are 20 / 22D and 27 / 29D; the specifications of the triacetate filament are 50D / 15F, 75D / 20F and 100D / 64F; and the specification of the wool yarn is 100Nm.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) In the present invention, it is considered that the crystallinity of silk fibroin in mulberry silk is low, and its chemical cross-linking property is relatively poor compared with other fibers. The wrinkle recovery property of silk fabric in wet state is poor. In order to improve the wrinkle resistance of the fabric, mulberry silk and acetate filament are firstly twisted together to form a composite filament yarn-silk vinegar composite yarn; in order to solve the problems of pilling and itching caused by the limitation of wool or cashmere and increase the fluffiness, resilience and comfort of the fabric, the silk vinegar composite yarn and wool yarn are twisted together to form a composite yarn with wool yarn as the core and the silk vinegar composite yarn wrapped in the outer layer-silk vinegar wool composite yarn; finally, the silk vinegar wool composite yarn is interwoven to form the final fabric.

[0032] (2) The silk-vinegar-wool composite yarn interwoven fabric of the present invention embodies the excellent properties of three materials: mulberry silk, wool and acetate fiber, improves the problems of pure silk fabric being easy to stick to the skin due to sweating, the itching feeling of pure wool fabric, and the silk-vinegar woven fabric not meeting the strength requirements, and improves the wrinkle resistance of the fabric. It can be dyed into a unique gray-colored fabric. Compared with single-component fabrics, the fabric has excellent wearing performance, is comfortable and easy to care for, has the touch and soft luster of silk fabric, is itchy, has a comfortable and natural drape, has good dimensional stability, improves the anti-pilling performance of the fabric, and has a certain anti-wrinkle effect. The fabric strength meets the standard requirements of silk fabrics. Compared with pure silk and pure wool fabrics of the same gram weight, the fabric cost is reduced, and the market competitiveness of the fabric is improved. BRIEF DESCRIPTION OF THE DRAWINGS
