Abstract

The invention relates to a method of forming a yarn by integrating nano electrostatic spinning and short fiber vortex spinning and belongs to the technical field of textile processing. A nano-powder release device and an electrospinning device are arranged above a front rubber-covered roller of each drafting mechanism of a friction spinning machine, an electrostatic spinning area is formed between an electrostatic spinning nozzle of the electrostatic spinning device and a receiving face of a receiving plate, nano fiber ejected by the electrostatic spinning area ejected to the receiving face that is covered with nano-powder to form a nano fiber mesh to which the nano-powder is adsorbed, the nano fiber mesh to which the nano-powder is adsorbed is discharged to a front roller jaw of a vortex spinning machine via a discharge face and is blended with drafted short fiber strands, and a blend then enters a vortex spinning machine and is twisted into a yarn; the nano fiber mesh to which the nano-powder is adsorbed and which is formed by nano spinning is subjected to filling and enhanced looping, and strength and finish fineness of the friction-spun yarn are improved; equipment related herein is simple to modify and is convenient to operate and use.

Description

technical field [0001] The invention relates to a method for integrating nanometer electrospinning and short fiber vortex spinning into yarn, which belongs to the technical field of textile processing. technical background [0002] Yarn structure directly determines yarn performance. The average porosity of ring-spun yarns with different linear densities is generally between 10% and 30%, but the average porosity of yarns with different linear densities is different. The thicker the yarn, the greater the average porosity; The porosity of the middle layer on the cross-section of the spindle yarn is the smallest, showing a compact structure, and the porosity of the outer layer of the yarn is the largest, showing a loose structure. Larger yarn porosity is the main factor for the yarn to have greater fluffy and breathable properties, but the larger the porosity, the looser the connection between the fibers in the yarn body, resulting in a decrease in the cohesion force between t...
