Polypropylene cloth and its application

Abstract

The invention relates to a polypropylene cloth and its application. The polypropylene cloth guide fabric is made of polypropylene filament yarns, and the yarn count is between 200-1000 denier, and the warp / weft yarn density is between 8-150 yarns / inch. And through actual production comparison, it is found that the polypropylene cloth guide cloth is used as the guide cloth of the open-width finishing machine in the textile industry, which has the advantages of high strength, good chemical corrosion resistance, long life and low price, which can greatly increase the service life of the guide cloth , Reduce the use cost of guide cloth.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a polypropylene cloth and its application. Background technique [0002] During the operation of the open-width finishing machine equipment used in the textile industry, the guide cloth must be used to sew the processing cloth. After the processing is completed, the guide cloth will be cut off and the guide cloth will be left in the equipment. When it is turned on again, it will be directly The processed cloth is sewn on the guide cloth, which can avoid re-threading the cloth every time the machine is turned on. At present, the textile industry generally uses strong and cheap cloth as the guide cloth to achieve the purpose of reducing the consumption cost of the guide cloth. However, in the open-width finishing process of the textile industry, many finishing machines need to use strong acid, strong alkali or strong oxidant. Moisture cross-linked resin finish...

AI Technical Summary

Problems solved by technology

During the repeated use of the machine, the traditional ordinary guide fabrics are continuously corroded by acids, alkalis, and oxidants, and their strength drops greatly. 2 Left and right) When used in the scouring and bleaching process of pure cotton cloth (need to use strong alkali and strong oxidant), polyester will be hydrolyzed under alkaline conditions, and cotton fiber will also be decomposed under the action of strong oxidant, use 3-8 times After that, it will be scrapped because the strength is too low, the guide cloth will be consumed seriously, and the cost will increase

Although pure synthetic fibers have high strength and are relatively cheap, they can be used as fabric guides, but most synthetic fibers have many problems and cannot be used as fabric guides, such as: polyester has poor alkali resistance and cannot be used in mercerizing machines; nylon is acid-resistant , Oxidant resistance is poor, and it cannot be used in moisture cross-linking and setting, scouring and bleaching; aramid fiber and fluorine fiber have better performance in all aspects, but the price is very high

In the traditional open width finishing process, there is no application of using polypropylene cloth as a guide cloth

And after experimental research, it was found that although the main performance of polypropylene cloth is excellent, it has the characteristics of large thermal shrinkage rate, smooth yarn surface and poor cloth surface slippage.

Large heat shrinkage makes the door width unstable, and poor slippage makes the cloth surface loose. When used as a cloth guide, there are defects such as difficult seaming operations and easy loosening of the selvedge on a finishing machine with a widening function.
