Composite yarn with non-destructive consolidation layered net powder-coated particles and its preparation method and device

Abstract

The invention provides a non-destructive consolidated layered mesh-coated powder-coated composite yarn and a preparation method and device thereof. Firstly, prepare the nano-micro composite anti-leakage strip and the mesh-coated powder prepolymer in sequence, and finally use the nano-micro composite anti-leakage strip and the mesh-coated powder prepolymer to carry out non-destructive consolidation oblique wrapping and twisting Spinning process, forming layered covered yarn, and then layered covered yarn enters the yarn consolidation chute of the consolidation device, and is subjected to high temperature thermal melting to form a non-destructive consolidated oblique coated yarn to achieve powder The non-destructive lock-embedded flexible composite yarn of granular materials solves technical problems such as the extrusion and damage of the particles when the particles are built into the spinning, and the easy untwisting and cracking of the yarn surface strips.

Description

technical field [0001] The invention relates to the technical field of textile material preparation, in particular to a non-destructive consolidated layered mesh-coated powder-coated composite yarn and a preparation method and device thereof. Background technique [0002] High-functional raw materials, especially rare earth, graphite and nanomaterials, mostly exist in the form of powder. The powder has a large specific surface area and strong physical and chemical activity. It is widely used in the fields of medicine, biology, electronics, military and aerospace, and is an important raw material for the functionalization of textiles. Functionalized textiles are made from textile processing; the key to textile processing is spinning. However, the powder particles are small, the continuity is poor, and the macroscopic length is short, which cannot meet the holding, pulling and torsional force requirements of industrial spinning, and direct torsional cohesion spinning encounte...

Problems solved by technology

[0005] However, this method has the following technical defects in the actual application of textile enterprises: First, during the preparation process of twisting the built-in particulate material into yarn, the yarn drawing roller squeezes the yarn body, resulting in the extrusion of the built-in particulate material in the yarn body. Pressure damage, causing nanoporous carbon microspheres with high adsorption function, microcapsules with drug sustained release function, polystyrene microspheres with hollow heat preservation function, and other particle structures to break and collapse, greatly weakening, or even completely losing the function of particles; 2. The surface structure of the yarn made by twisting the built-in particulate material in the strip is a physical wrapping structure of fiber strips. There are powder particles that are easy to leak from the gap in the wrapping. When the yarn is used, the strip on the yarn surface is easy to untwist. cracking problem
