Problems solved by technology

[0002] Fabrics woven from silk protein fibers have the characteristics of soft luster, smooth and soft feel, good moisture absorption and breathability, and light appearance, and are favored by people. Insufficient weak resistance, when the silk garments are worn, they are generally exposed to defects such as easy deformation, poor shape retention, large seam slippage, poor durability and other defects, which affect their wide application in the field of clothing. application
[0003] At present, the market has a large demand for silk elastic fabrics, and the existing silk elastic fabrics contain a certain amount of synthetic fibers, such as adding spandex to silk fabrics, and then interweaving with silk threads to form an interwoven fabric of silk threads and spandex. Or it is a stretch fabric made of wrapped silk made of silk thread and elastic fiber, all of which contain spandex fiber, so it is a non-green, environmentally friendly pure natural renewable fiber product, while synthetic fiber silk stretch fabric is also There is a phenomenon that the elasticity near the two sides of the fabric is small and the elasticity is large in the center, and the air permeability, wearing comfort, moisture absorption and heat retention of the product are all reduced

Embodiment 1

[0016] The specific process is as follows:

[0017] 1. Weaving of pure silk weaving natural elastic gray silk

[0018] The technological process is the selection of warp and weft, the selection of weft twist and twist direction, the twist arrangement of weft combination, the selection of fabric weave and the warp and weft density of gray silk.

[0019] The warp is selected as 2 / 20 / 22D mulberry silk 15T / 10cm S, the door width of the upper machine is 122CM, the inner warp: 14460, the upper machine warp density: 1200 / 10cm, the number of reed penetration: 6;

[0020] The number of weft combinations is 2 groups, one group uses [(1 / 20 / 22D mulberry silk 450T / 10cm S)×2] 360T / 10cm S two shuttles, and the other group uses [(1 / 20 / 22D mulberry silk 450T / 10cm Z)×2] 360T / 10cm Z two shuttles.

[0021] The SSZZ order is adopted in the arrangement of weft insertion to ensure the stress balance and stability of the finished fabric surface after subsequent degumming and other finishing of th...

[0033] The specific process is:

[0034] 1. Weaving of pure silk weaving natural elastic gray silk

[0035] The warp is selected as 3 / 20 / 22D mulberry silk 25T / 10cm Z, the door width of the upper machine is 122CM, the inner warp: 6710, the upper machine warp density: 550 / 10cm, the number of reed penetration: 2;

[0036] The number of weft combinations is 2 groups, one group uses [(1 / 20 / 22D mulberry silk 450T / 10cm S)×2] 360T / 10cm S, and the other group uses [(1 / 20 / 22D mulberry silk 450T / 10cm S) ×2] 360T / 10cmZ.

[0037] The SZSZ order is adopted in the weft insertion arrangement to ensure the stress balance and stability of the finished fabric surface after the subsequent degumming and other finishing of the fabric.

[0038] The fabric weave adopts plain weave, and the weft density on the upper machine is 355 threads / 10cm.

Abstract

The invention discloses a production method for enabling a pure mulberry silk fabric to have a natural elasticity style in a weft direction. The technological processes sequentially comprise blank silk weaving, preprocessing, cooked smelting, bleaching, water washing, pickling, dewatering or squeezing, coiling, baking stentering and check mounting, wherein the cooked smelting comprises primary smelting and secondary smelting. The baking stentering comprises the following steps: firstly, carrying out baking shaping on a wool carpet finishing machine and then at least carrying out stentering processing for more than two times on a stentering machine. The technological processes of the blank cloth weaving comprise the selection of wefts, the selection of the twisting degree and the twisting direction of the wefts and the twisting direction arrangement of weft combination. Because the pure mulberry silk fabric does not depend on elastic fibre, such as urethane elastic fibre and the like, and adopts blank silk woven by super-strong twisting real silk wefts to carry out the methods of degumming, stentering, shaping and processing so as to enable a pure real silk fabric to obtain better weft direction elasticity and excellent elastic restoring force, the fabric is not easy to crack and has relatively flexible hand feel and good moisture absorption and air permeability, and a dress article made by the fabric shapes the body and has convenient movement, good form retention, small dimensional change rate and small seam slippage.
