Device and method for detecting dispersing performance of chemical synthesized short fibers

Abstract

The invention discloses a device and a method for detecting the dispersing performance of chemical synthesized short fibers. The device is characterized by being vertically provided with a cylinder; a middle filtering layer is arranged in the cylinder; a stirring shaft for forming a dispersing stirrer is axially arranged above the middle filtering layer; a water inlet pipe which is provided with a water inlet valve and a liquid discharge pipe which is provided with a liquid discharge valve are respectively arranged below the middle filtering layer; the middle filtering layer comprises a filter screen and a filter cloth which is arranged on the filter screen; and an air inlet pipe is radially arranged on the side wall of the cylinder, at the bottom of the stirring shaft and above a middle interlayer. The invention has compact device structure and simple and convenient method operation and can be used for rapidly and accurately detecting various defects of paralleled yarns, sticking yarns, doubling yarns, gommures, and the like existing in the chemical synthesized short fibers by the dispersing situation of the short fibers in water.

Description

technical field [0001] The invention relates to a detection device and a detection method for detecting the dispersion performance of chemically synthesized short fibers. Background technique [0002] Chemically synthesized short fibers are made of high molecular polymers through dissolution (or melting), spinning, coagulation, drawing, setting, winding, cutting and other production processes. In its production process, various defects such as doubling, continuous sticking, doubled filaments, and rubber blocks may occur. The existence of defects directly affects the dispersion performance of short fibers, thus affecting the quality and use effect of short fibers. Therefore, accurate detection is required to be strictly controlled. [0003] At present, raw cotton analysis machines or hand-held methods are used to detect various defects in China. The raw cotton analysis machine is composed of a carding machine and a cleaning machine. According to the principle of aerodynami...

AI Technical Summary

Problems solved by technology

[0004] 1. Defects such as small parallel wires or small continuous sticky wires cannot be separated or sorted out, resulting in inaccurate test results

[0005] 2. In the process of carding with raw cotton analysis machine, large parallel yarn or Dalian sticky yarn may be damaged and be carded into small parallel yarn or small continuous sticky yarn, which will distort the test results
