Method of integrating nano-electrospinning and short-fiber friction spinning into yarn

Abstract

The invention relates to a method of forming a yarn by integrating nano electrostatic spinning and short fiber friction spinning and belongs to the technical field of textile processing. A corresponding fiber transfer passage exit end of each drafting mechanism of a friction spinning machine is provided with an electrostatic spinning device, an electrostatic spinning area is formed between an electrostatic spinning nozzle of the electrostatic spinning device and a receiving face of a receiver, a nano fiber mesh ejected by the electrostatic spinning area is blended with short fiber strands that enter the receiving face after being drafted by a drafting system of the friction spinning machine, and a blend then enters between a pair of friction rollers and is twisted into a yarn; electrostatic spinning and friction spinning are organically combined in a whole, high-speed smooth production of nano-micro fiber yarns is guaranteed, the nano fiber mesh 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 yarn-forming method integrating nano-electrospinning and short-fiber friction spinning, 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 the f...
