Embodiment approach 1

[0023] figure 1 Described, the technology realized by the present invention comprises the following steps:

[0024] A. Production of cored wire:

[0025] Spandex is first stretched according to a certain draft ratio, then nylon is used as the outer wrapping yarn, and it is wrapped on a high-speed wrapping machine to make a core-spun yarn (CR) suitable for weaving;

[0026] The spandex is 20D type spandex, the outsourcing yarn is nylon DT12 / 7 type (DT20 / 5 or other types can also be selected according to needs), the motor speed is 20000 rpm, the draft ratio is 3, the twist is 1300T / M, and the overfeed is 94 %, the working temperature is 25°.

[0027] B. Weaving:

[0028] After the core-spun silk (CR) is balanced for a certain period of time (5 days, the temperature is controlled at 25°), the core-spun silk is fed into the knitting machine for weaving to make semi-finished stockings;

[0029] On each thread path of the knitting machine, use KTF (automatic yarn feeder), throug...

Embodiment approach 2

[0040] A. Production of cored wire:

[0041] The special spandex is first stretched according to a certain draft ratio, and nylon is used as the outer wrapping yarn, which is wrapped on a high-speed wrapping machine to make a core-spun yarn suitable for weaving;

[0042] Choose 15D model for spandex, DT12 / 7 model for nylon (or DT20 / 5 or other models according to needs), the motor speed is 25000 rpm, the draft ratio is 2, the twist is 1800T / M, and the overfeed is 95%. The temperature is 20°.

[0043] B. Weaving:

[0044] After the core-spun silk is balanced for a certain period of time (7 days, the temperature is controlled at 20°), the core-spun silk is sent into the knitting machine for weaving to make semi-finished stockings;

[0045] On each thread path of the knitting machine, use KTF (automatic yarn feeder), through the buffering and balancing effect of KTF, the tension of each thread is controlled to 0.15-1G, thus solving the problem of poor texture; by adjusting The ...

Embodiment approach 3

[0055] A. Production of cored wire:

[0056] Spandex is first stretched according to a certain draft ratio, and nylon is used as the outer wrapping yarn, which is wrapped on a high-speed CV machine to make a core-spun yarn suitable for weaving;

[0057] Spandex uses 70D type spandex yarn, nylon uses DT12 / 7 type (DT20 / 5 or other types can also be selected according to needs), the motor speed is 22000 rpm, the draft ratio is 2.5, the twist is 1600T / M, and the overfeed is 94.5%. , the working temperature is 22°.

[0058] B. Weaving:

[0059] After the core-spun silk is balanced for a certain period of time (8 days, the temperature is controlled at 22°), the core-spun silk is sent to the weaving workshop for weaving to make semi-finished stockings;

[0060] On each thread path of the knitting machine, use KTF (automatic yarn feeder), through the buffering and balancing effect of KTF, the tension of each thread is controlled to 0.15-1G, thus solving the problem of poor texture; b...

Abstract

The invention relates to a process for producing a spandex core-spun run resistant hosiery, which comprises the steps of manufacturing of core-spun yarns, weaving, dyeing and shaping, wherein during shaping, the core-spun yarns are melted by adopting proper temperature, so that the woven core-spun yarns are mutually adhered to form a net lace structure; the core-spun yarns among the hosiery net lace are mutually adhered, so that a compact netted structure is formed between the transverse direction and the longitudinal direction of the hosiery to change the prior weaving structure; and even if one or more of yarns of the hosiery are broken, the broken yarns are not laddered due to the adhering relation of the net laces, so the hosiery has the run resistant function.

Description

technical field [0001] The invention designs a production process of silk stockings, specifically a production process of brocade ammonia wrapping silk stockings, which can effectively produce loosening-proof stockings. Background technique [0002] Silk stockings have become a necessity in modern women's life. They not only have the function of wearing, but also have aesthetics. At present, the raw materials of high-end stockings are usually made of spandex and nylon filaments, that is, nylon filaments are used to wrap spandex filaments. The core-spun silk is formed, and the core-spun silk is woven into stockings and then dyed, shaped, packaged, and sold as a finished product. However, stockings are weft-knitted plain weave products made of ordinary core-spun silk. Once they are accidentally hung during wearing, the stockings will quickly spread longitudinally along the hole, which will lose both the aesthetic effect and the function of socks. , can only be thrown away, ca...
