Embodiment 1

[0025] A production method of cashmere weft elastic fabric, comprising the following steps:

[0026] (1) High elasticity of silk: silk degumming to obtain cooked silk, two cooked silks with a fineness of 20 / 20D are twisted to a twist of 27T / cm; then the twisted filaments are flattened through oxygen plasma reaction The vacuum degree is 40Pa, the power is 50W, and the low-temperature oxygen plasma is treated for 10min; then untwisted to obtain high elastic silk.

[0027] (2) Spinning weft yarn: take high elastic silk as the core yarn, take 60-70 counts of semi-worsted cashmere yarn as wrapping yarn, and semi-core wrapping yarn to prepare elastic wrapping yarn as weft yarn; in the weft yarn, cashmere yarn and The mass ratio of high elastic silk is 6:1.

[0028] (3) Spinning warp yarn: warp yarn is made by blending cashmere fiber and common silk fiber; wherein, the fineness of mulberry silk fiber is 10.5 μm, and the average length is 40mm; the average fineness of cashmere is 15....

Embodiment 2

[0032] A production method of cashmere weft elastic fabric, comprising the following steps:

[0033] (1) high elasticity of silk: silk degumming to obtain cooked silk, two cooked silks with a fineness of 20 / 20D are twisted to a twist of 18T / cm; then the twisted filaments are flattened through oxygen plasma reaction Cavity, low temperature oxygen plasma treatment for 1min, vacuum degree of 30Pa, power of 100W; after the low temperature plasma treatment, the twisted filaments continue to be heated at a temperature of 70℃, containing 1% sodium nitrate and 1% sodium chloride. Immerse in a dilute solution for 1 min, where the concentration is a weight percent concentration, then centrifuge, wash with water, dry, and untwist to obtain high-elasticity silk.

[0034] (2) Spinning weft yarn: take high elastic silk as core yarn, take 60-70 count semi-worsted cashmere yarn as wrapping yarn, semi-core wrapping yarn, prepare elastic wrapping yarn as weft yarn, among which cashmere yarn and...

Embodiment 3

[0039] A production method of cashmere weft elastic fabric, comprising the following steps:

[0040] (1) High elasticity of silk: silk degumming to obtain cooked silk, two cooked silks with a fineness of 20 / 20D are twisted to a twist of 25T / cm; then the twisted filaments are flattened through oxygen plasma reaction chamber, low temperature oxygen plasma treatment for 3min, vacuum degree is 36Pa, power is 60W; after low temperature plasma treatment, the twisted filament is twisted in the same direction for 20T / cm, and then the temperature is 50℃, the weight is 100W. Dip in a dilute solution with a concentration of 1% sodium chloride for 1 min, centrifuge, wash with water, dry and untwist to obtain high elastic silk.

[0041] (2) Spinning weft yarn: take high elastic silk as the core yarn, take 60-70 counts of semi-worsted cashmere yarn as wrapping yarn, and semi-core wrapping yarn to prepare elastic wrapping yarn as weft yarn; in the weft yarn, cashmere yarn and The mass ratio...

Abstract

The invention discloses a cashmere weft stretch fabric production method which includes the steps: (1) silk high stretching: twisting filament yarns by degumming silk and untwisting the twisted filament yarns after low temperature plasma treatment to obtain high-elasticity silk; (2) weft yarn spinning: taking the high-elasticity silk as core yarns, taking cashmere yarns as fasciated yarns and preparing elastic fasciated yarns serving as weft yarns; (3) warp yarn spinning: blending cashmere fibers and common silk fibers to prepare warp yarns; (4) weaving: weaving a twill or satin fabric by thewarp yarns and the weft yarns; (5) after-finishing. Compared with the prior art, the production method has the advantages that no chemical fibers are added, a cashmere fabric acquires weft elasticityonly by the aid of natural fibers and a certain treatment, natural elasticity of cashmere and the gloss of the silk are retained, the cashmere fabric is suitable for serving as a fabric for trousers,overcoats and dresses, the problem of easiness in looseness of a traditional cashmere fabric is solved, and poor wrinkle resistance of the fabric caused by silk containing can be overcome as the fabric can elastically recover.

Description

technical field [0001] The invention relates to a method for producing fabrics, in particular to a method for producing cashmere weft elastic fabrics. Background technique [0002] Cashmere fabric is a woolen product made of high-quality natural cashmere fiber. With its "soft, soft, light, smooth, warm and cool" characteristics, it has become a high-end, high-quality fashion product pursued by consumers. . However, as cashmere fabrics for pants, coats and skirts, it is prone to the problems of loose cashmere and poor recovery. [0003] Weft elastic fabric, referred to as weft elastic fabric for short, can only stretch and rebound from left to right, and has little up and down deformation. However, the current weft elastic fabrics are generally woven by adding highly elastic chemical fibers, such as spandex, to the weft yarns. The addition of chemical fibers affects the quality and grade of cashmere fabrics, making the fabrics less hygroscopic, stuffy, airtight, and poor i...
