Double core core-spun yarn -- Wuxi Hezhan Intelligence

Double core spun yarn is a twisted yarn with staple fiber as raw material and two kinds of filament with different characteristics as core. Due to the different properties of the two core yarns, strong complementarity is produced, so that the yarn has more superior characteristics. Such as cotton package T400+ spandex. Using these two kinds of filament as core yarn, the yarn produced by outsourced cotton fiber not only maintains good moisture absorption, softness, and elasticity of cotton spandex yarn, but also has higher strength, wear resistance, and dimensional stability. The fabric produced by this yarn has no sense of bondage, pressure and relaxation when wearing. And wear - resistant, high tearing strength, small shrinkage rate, good shape - preserving.

Double core yarn production key

Double core yarn is to introduce two kinds of filament into the clamp mouth of the front roller and the cots of the spinning frame through the guide wire wheel, and wrap and twist them through the short fiber. Different filaments need to be given different pre-draft tension. Let them play to their own characteristics. One of the key points of production is to control the tension and stability of filament. Ensure the same spindle tension and inter-spindle tension. Because the filament tension fluctuation will directly affect the fabric door width change. At present, the pre - draft tension control of spandex yarn is mature. But the tension control of the other filament is still being explored. At present, active filament feeding device is widely accepted.

Wuxi and zhan double core yarn device scope of application

Can be spun cotton, hemp, chemical fiber and other spandex elastic core-spun yarn, and double core-spun yarn, yarn range of 6S-30s;

Main features:

1. Hezhan spandex core-spun yarn and double core-spun yarn device are used with various spinning frames;

2. Double wire adopts active feeding form. Spandex core-spun yarn and filament core-spun yarn each have a servo drive, so that the two core-spun yarns are fed synchronously to ensure the same feeding proportion.

3. Equipped with spandex core-spun yarn device and filament core-spun yarn device, double core-spun yarn can be spun, or spandex core-spun yarn and filament core-spun yarn can be spun independently. Spandex core-covered yarn can be customized according to customer requirements.

4. Spandex draft can be adjusted from 1.3 to 5 times, filament draft can be adjusted from 1 to 2 times.

5. The roller can choose seamless steel tube chromium plating (black and white color optional) or hard aluminum alloy roller (with groove), draft ratio is stable, can ensure the quality of yarn. The newly designed roller connection has self-unloading function, easy to install and maintain.

6. The guide wire wheel can rotate flexibly, and the specifications and models can be adjusted freely within a certain range

Wuxi Hezhan spinning electromechanical equipment, after more than ten years of research and development production, from the past sluice yarn, segment color yarn on the basis of research and development of intelligent spinning equipment, open the intelligent manufacturing, promote the overall development of enterprises, better committed to the development of the spinning industry.
