A micro-nano fiber multi-layer structure core-spun yarn spinning device and its production process

Abstract

The invention discloses a core-spun yarn spinning device with a micro-nano fiber multi-layer structure and a production process thereof, comprising a yarn feeding device, a twisting device, a receiving device and a winding device. The yarn feeding device includes a yarn core on which Core yarn, the twisting device is composed of the first twisting roller and the second twisting roller, the core yarn is introduced between the first twisting roller and the second twisting roller through the yarn guide rod, and the micro-nano fiber layer is covered to form a package For the core yarn, the winding device includes a bobbin and a winding roller. The core-spun yarn passes through the yarn guide rod, and the winding roller drives the bobbin to wind the core-spun yarn. The core yarn of the present invention adopts conductive heating fiber filament, and the covering fiber adopts PBT chip and PET chip to mix in different proportions to form two kinds of micro-nano fibers with different components, fineness, thickness and bulkiness. Micro-nano fiber core-spun yarn with multiple functions such as conductive heating, heat preservation, antibacterial, breathable, etc., is soft and comfortable, and can be widely used in the production of various textile fabrics to meet the needs of textile product development.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a core-spun yarn spinning device with a micro-nano fiber multi-layer structure and a production process thereof. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a yarn composed of two or more fibers. The structure of the core-spun yarn is mainly composed of the core yarn and the covering layer. Generally, the synthetic fiber filament with good strength and elasticity is used as the core yarn, and the outsourcing cotton, wool, chemical fiber and other short fibers are twisted and spun together. . Therefore, the core-spun yarn has both the excellent properties of the filament core yarn and the outer short fiber. The methods of spinning core-spun yarn mainly include ring spinning, friction spinning, and air-jet spinning for core-spun yarn production. [0003] Electric heating fiber is a composite fiber containing electric heating ma...

Problems solved by technology

Whether it is carbon fiber or graphene fiber, the color of the fiber is black or gray-black depending on the carbon content, and the base material of the fiber is mainly nylon or polyester, which severely limits the scope of application.
