Problems solved by technology

But so far, there are relatively few technologies that combine electrospinning and vortex spinning technology to prepare functional composite yarns. Wool fiber has excellent thermal performance, moisture absorption performance and mechanical properties, but it is easy to be eaten by insects and difficult to preserve. Using wool as raw material, electrostatic The functional composite yarn prepared by the combination of spinning and vortex spinning technology will be very marketable

Abstract

The invention discloses a preparation method of an antibacterial and insect-proof heat-generating composite yarn. The spinning solution is electrostatically spun, so that the produced fibers are attached to the surface of the fine wool yarn to form the primary yarn; S2. The primary yarn obtained in step S1 is fed into the vortex spinning equipment, and blended with the cotton fiber, that is, the primary yarn is formed. The antibacterial and insect-proof heat-generating composite yarn is described. The composite yarn prepared by the invention not only has the characteristics of good hygroscopicity, excellent elasticity and good warmth retention of the traditional wool yarn, but also has the advantages of antibacterial and moth-proof, and self-heating after being irradiated by far infrared rays.

Description

technical field [0001] The invention relates to the technical field of yarn production, in particular to an antibacterial and insect-proof heat-generating composite yarn and a preparation method thereof. Background technique [0002] At present, the application of vortex spinning and electrospinning in the preparation of functional yarns has achieved certain development, and there have been some successful cases of manufacturing composite yarns. The invention discloses a method for producing easily hygroscopic vortex spinning yarn, wherein the composite yarn with excellent water absorption performance is obtained by vortex spinning of polyester fiber, cotton fiber and sisal fiber. Chinese patent CN201310586642.X proposes a preparation method of nanofiber composite yarn, which successfully prepares composite yarn with higher added value through electrospinning technology. However, so far, there are relatively few technologies that combine electrospinning and eddy current spi...
