Embodiment 1

[0020] The process step that present embodiment adopts is:

[0021] Raw materials, winding, twisting, rewinding, knitted fabric weaving, pretreatment, dyeing, creping, drying, finishing, finished products.

[0022] 1. Raw material: The raw material of this embodiment selects a real silk-coated spandex yarn with a linear density of 20-25 denier side-by-side silk spandex-coated yarn, and the twist is 50-100 twists / meter.

[0023] 2. Winding: according to the conventional process of silk winding;

[0024] 3. Twisting: according to the existing routine process of silk twisting;

[0025] 4. Rewinding: according to the existing routine process of silk rewinding;

[0026] 5. Weaving: Weaving is carried out on a large circular knitting machine;

[0027] 6. Pretreatment: Scouring treatment is carried out on a silk scouring machine or a low-tension rope overflow machine. The purpose is to remove impurities such as oil and sericin on real silk knitted fabrics, improve the wool effect ...

Embodiment 2

[0036] The raw materials are two silk-coated spandex yarns, each spandex / silk-coated yarn has a linear density of 40-45 denier, and the twist of the wrapped spandex / silk-coated yarn is 1000-1500 twists / m. In the previous processing, two yarns are used to weave silk knitted fabrics on a knitting machine.

[0037] The printing and dyeing process includes scouring, dyeing, creping, finishing and other processes. The scouring process conditions are: scouring temperature 95-115°C, time 60-120 minutes, bath ratio 1:25-50, rapid scouring agent (such as AR-617) 3-10g / L, soda ash 3-10g / L. The one-step dyeing and creping process conditions are: 2% acid dye, use acetic acid or acetic acid / sodium acetate to adjust the pH of the dye solution to 4-5.5, 5% hydrophilic carbamate polymer, hydrophilic polypeptide protein The polymer is the hydrolyzate of silk fibroin protein with a concentration of 0.5%, the bath ratio is 1:15-30, the temperature is 90-120°C, and the time is 60-120 minutes. Th...

Abstract

The invention relates to urethane elastic fiber / silk crape ground knitted fabric and its manufacturing method. It includes the following steps: using urethane elastic fiber as centre thread; covering its outer layer with silk composite yarn to form knitted fabric; putting in corrugating processing liquid formed by 0.5-5% hydrophilicity carbamates high molecule matter and 0.5-3% hydrophilicity polypeptide protein high molecule matter to gain cycle junction state urethane elastic fiber / silk crape ground knitted fabric. It utilizes the shrinking of the urethane elastic fiber heat yarn and the no shrinking of the silk yarn outer layer to make special loop crape ground structure to realize crape ground effect. The formed fabric has good resiliency, little washing deformity, good feel, moisture absorption, and quick drying effect. It overcomes the defect that the traditional silk crape clothes is easy to stick together caused by human body perspiring, and increases its comfortable.

Description

technical field [0001] The invention relates to a spandex / silk crepe knitted fabric and a preparation method thereof, in particular to a spandex / silk covered yarn knitted fabric to form a crepe knitted product and a crepe processing method thereof. Background technique [0002] Crepe style fabrics have always been the focus of silk and cotton product development. The main feature of crepe products is the "crepe effect". In addition, crepe products are also characterized by soft texture, lightness, elasticity, lively and natural, and various forms. , favored by consumers. There are many methods of fabric creping. One is to achieve the crepe effect of textile fabrics through raw materials, yarns, and fabric structures; the other is to produce crepe effects on the surface of textile fabrics through chemical, physical and mechanical methods after printing and dyeing. At present, the commonly used methods are: (1) strong twist yarn fabric: crepe is produced by changing the combi...
