Online sizing spinning machine and sizing method of cellulose fiber yarn at room temperature

Abstract

The invention belongs to the technical field of ring spinning, and relates to an online sizing spinning machine and sizing method of cellulose fiber yarn at room temperature. The sizing spinning machine comprises a ring spinning frame and a sizing device; the sizing device is fixed on the ring spinning frame through a fixed plate, and the sizing device is located between a front roller clamp and ayarn guide hook of the ring spinning frame, and a yarn twisting section output from the front roller clamp is sized through the sizing device. A motor is connected with a pulping guide roller througha rotor shaft and drives the pulping guide roller to rotate; the bottom of the pulping guide roller is immersed in the slurry of the lower pulp groove. A circulating device is fixed at the bottom ofthe pulp groove. The online sizing spinning machine of cellulose fiber yarn at room temperature adds an on-line sizing device to the yarn twisting section between the front roller clamp and the yarn guide hook, combines the environmental friendly grout which is suitable for the normal temperature single yarn sizing of cellulose fiber yarn and carries out the sizing process on the yarn twisting section between the front roller clamp and the yarn guide hook, the spinning process is combined with the sizing procedure, and the obtained fine yarns can be used directly for weaving.

Description

Technical field [0001] The invention belongs to the technical field of ring spinning, and relates to a cellulose fiber spun yarn at room temperature on-line sizing spinning machine and a sizing method. Background technique [0002] The traditional ring spinning method has a long history and simple structure. Because of its wide range of suitable spinning density, strong adaptability of raw materials, and good yarn quality, it has always been an important spinning method that accounts for more than 80% of the entire yarn output. The unsizing yarn produced in the spinning process has long and large hairiness on the surface, poor cohesion between fibers, and its performance is not enough to directly withstand more than 3000 times of stretching, buckling and abrasion on high-speed looms. Such yarns Under the action of complex mechanical force, the yarn body is easy to fluff, resulting in yarn disintegration and breakage. The fluffing of the yarn body will also cause the yarns to adhe...

In addition, the Chinese invention patent application with the publication number CN106702554A "A Ring Spinning Machine with a Moisture Supply Device for Reducing Hairiness" uses liquid Water feed wet guide wheel wet device to reduce yarn hairiness; French patent application with publication number FR2817878A1 "A hairiness reduction device for spinning frame" proposes a method to reduce the twisting triangle in the process of hemp spinning , and fully wet the hemp fiber strands between the nip of the front roller and the yarn guide hook. After the fiber strands come out of the jaws of the front roller, they immediately contact the ceramic rod to reduce the twisting triangle area, and then pass through the water injection pipe In the humidification area composed of water bath rollers, the water is passed through the water injection pipe to directly immerse the yarn in the water. After the water falls, it enters the water tank and is recycled. There are water bath rollers in the water tank. The process can be done with water or with a water-based solution, but this process does not give the composition of the water-based solution and the specific yarn performance improvement effect, and this process is aimed at hemp spun yarn, not suitable for cotton ring spinning
