Abstract

The invention belongs to the technical field of textile, and relates to a production process for a full-elastic silk knitted fabric. The production process comprises the following steps of: (A) preparation of core spun yarns; (B) winding; (C) knitting; (D) scutching; (E) high-temperature setting; (F) refining; (G) secondary high-temperature setting; (H) dyeing; and (I) steam flattening, so that the full-elastic silk knitted fabric is obtained. The production process is easy to implement, low in production cost and high in yield; and a product produced by the production process is high in quality and wide in application range, and is completely applied to various tatting and knitting requirements, and wide uses are developed for the conventional actual application of silk.

Example Embodiment

[0026] Example 1

[0027] A fully stretched silk knitted fabric produced by the production process of the present invention is produced through the following production steps:

[0028] A. Preparation of core-spun yarn: the silk 1 is uniformly attached to the surface of the spandex yarn 2 by reeling to obtain the core-spun yarn;

[0029] B. Winding: Twist and wind the core-spun yarn into a core-spun yarn tube for knitting and weaving;

[0030] C. Knitting weaving: including weft knitting and warp knitting, weft knitting is to place each yarn of the core-spun yarn tube on each needle of the weft knitting machine sequentially along the weft direction to form a weft knitted fabric. In warp knitting, the yarns are wound in parallel to form a warp beam, and then produced on the machine to obtain a rope-like silk fabric;

[0031] D. Open width: Extend the rope-like silk fabric into an open width state;

[0032] E. High temperature setting: Place it for 10 minutes in an environment with a temperature of 180℃;

[0033] F. Smelting: Put the core-spun silk tube into the container, pour water into the container and adjust the alkali concentration to 3.0% (mass percentage), heat to 50°C, and keep the temperature for 45 minutes;

[0034] G. Secondary high temperature setting: Place it for 5 minutes in an environment with a temperature of 190℃;

[0035] H. Dyeing: select dyed blanks, separate colors, and then dye the fabrics that have undergone secondary high temperature setting;

[0036] I. Steam mud flattening: Put the dyed fabric in a steam high pressure 5Pa environment for 20 minutes to flatten it to obtain a fully elastic silk knitted fabric.

[0037] Then, test the extensibility, softness, color absorption, silkiness, production cost and yield of the full stretch silk knitted fabric. The test results are listed in Table 1.
