Manufacturing process of spun-bonded non-woven fabric

Abstract

The invention relates to a manufacturing process of spun-bonded non-woven fabric. A device implementing the manufacturing process comprises a workbench, a conveying device and a processing device, wherein the conveying device is fixedly installed at the upper end of the workbench, the processing device is fixedly installed at the upper end of the left side of the conveying device, and the conveying device comprises a heat preservation barrel, a heating plate, a glass plate, a first motor, a screw rod, a filtering plate, a conveying pipe and a heat preservation pipe. Polyester slices are heatedthrough the conveying device and are completely in a molten state, so that processing quality is prevented from being affected, meanwhile, liquid polyester attached to the inner wall of a part is scraped to prevent a utilization rate of the polyester from being affected, and polyester raw materials are sliced through the processing device and screened, so that the polyester slices which do not meet the standard are prevented from entering the conveying device and thus prevented from affecting the processing efficiency, meanwhile, the particle size of the polyester slices can be limited as required, and thus the use efficiency of equipment is improved.

Description

technical field [0001] The invention relates to the field of non-woven fabric manufacturing, in particular to a spun-bonded non-woven fabric manufacturing process. Background technique [0002] The main materials of spunbonded non-woven fabrics are polyester and polypropylene. The processing method is usually to extrude and stretch the polymer to form continuous filaments. Chemical bonding or mechanical reinforcement methods make the fiber web into a non-woven fabric, and the spunbonded non-woven fabric has the advantages of high strength and good high temperature resistance. [0003] In the process of processing and manufacturing spunbonded non-woven fabrics, since the polyester needs to be sliced ​​and the liquid polyester in the molten state needs to be transported, the following problems exist in the actual operation process: [0004] (1) When traditional spunbonded non-woven fabric manufacturing equipment slices polyester raw materials, it is difficult to continue twis...

AI Technical Summary

Problems solved by technology

[0004] (1) When traditional spunbonded non-woven fabric manufacturing equipment slices polyester raw materials, it is difficult to continue twisting and slicing polyester raw materials. At the same time, polyester slices of different standards have different sizes, and the use efficiency of the equipment is low. At the same time, it is very easy to affect the subsequent processing and manufacturing

[0005] (2) When the traditional spunbonded non-woven fabric manufacturing equipment heats the polyester chips, the polyester is easily transported to the processing place under the drive of the molten liquid polyester when it is not completely melted, thus affecting the processing and manufacturing quality At the same time, the liquid polyester in the molten state is very easy to adhere to the inner wall of the part, thus affecting the processing efficiency and the utilization rate of polyester
