Embodiment 1
[0025] A kind of production method of cashmere weft elastic fabric, comprises 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 plied and twisted to a twist of 27T / cm; then the twisted filaments are straightly subjected to oxygen plasma reaction chamber, the vacuum degree is 40Pa, the power is 50W, and the low-temperature oxygen plasma is treated for 10 minutes; and then untwisted to obtain high-elastic silk.
[0027] (2) Spinning weft yarn: take highly elastic silk as core yarn, semi-worsted cashmere yarn with 60-70 counts as wrapping yarn, and half core-spun yarn to prepare elastic wrapping yarn as weft yarn; in weft yarn, cashmere yarn and The mass ratio of high elastic silk is 6:1.
[0028] (3) Spin warp yarn: make warp yarn with the blending of cashmere fiber and common silk fiber; Wherein, the fineness of mulberry silk fiber is 10.5 μm, and the average length is 40mm; The avera...

[0032] A kind of production method of cashmere weft elastic fabric, comprises 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 plied and twisted to a twist of 18T / cm; then the twisted filaments are straightly subjected to oxygen plasma reaction Chamber, low temperature oxygen plasma treatment 1min, vacuum degree is 30Pa, power is 100W; Immerse in the dilute solution for 1min, where the concentration is the concentration by weight, then centrifuge, wash with water, dry and untwist to obtain highly elastic silk.
[0034] (2) Spinning weft yarn: take high elastic silk as core yarn, semi-worsted cashmere yarn of 60-70 counts as wrapping yarn, half core-spun yarn to prepare elastic wrapping yarn as weft yarn, wherein cashmere yarn and high elastic The mass ratio of silk is 9:1.
[0035] (3) Spin warp yarn: make warp yarn with the blending of cashmere fiber and common silk fiber; Wherein...
Embodiment 3
[0039] A kind of production method of cashmere weft elastic fabric, comprises 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 plied and twisted to a twist of 25T / cm; then the twisted filaments are straightly subjected to oxygen plasma reaction Chamber, low-temperature oxygen plasma treatment for 3min, vacuum degree of 36Pa, power of 60W; after low-temperature plasma treatment, the twisted filaments are twisted in the same direction at 20T / cm, and then heated at a temperature of 50°C and a weight of 100 Soak in a dilute solution with a concentration of 1% sodium chloride for 1 min, centrifuge, wash with water, dry, and untwist to obtain highly elastic silk.
[0041] (2) Spinning weft yarn: take highly elastic silk as core yarn, semi-worsted cashmere yarn with 60-70 counts as wrapping yarn, and half core-spun yarn to prepare elastic wrapping yarn as weft yarn; in weft yarn, cashmere y...
