Superfine polyester carpet yarn

Abstract

The invention relates to superfine polyester carpet yarn belonging to the technical field of carpet yarn. The invention is characterized that the superfine polyester carpet yarn is formed by doubling and twisting 346dtex polyester low-elastic yarn or 2267dte polyester low-elastic yarn, adopts a first technical scheme by once doubling three pieces of 346dtex polyester low-elastic yarn into one, twisting S, twice doubling two pieces of twisted yarn into one and twisting Z, and a second technical scheme by doubling three pieces of 2267dte polyester low-elastic yarn into one, twisting S, twice doubling two pieces of twisted yarn into one and twisting Z. The invention needs to dye at high temperature and pressure, but has less production procedures, easy operation, high spinning yield rate and low production cost, much stronger strength than carpet yarn produced by other short fibers and good resilience; and a textured carpet has soft foot feeling and good crease resistance and is easy to clean.

Description

technical field [0001] The invention belongs to the technical field of carpet yarns, in particular to an ultrafine polyester carpet yarn. Background technique [0002] With the improvement of people's living standards in our country, the use of carpets in units and families is becoming more and more common, especially the demand for cheap and high-quality chemical fiber carpets is increasing. However, the existing chemical fiber carpet yarn has the following disadvantages: first, the traditional ring spinning process is adopted, the production process is numerous, the operation is difficult, the spinning rate is low, and the processing and production cost is high; The strength of the carpet yarn is not high; the third is that the woven carpet is not soft; the wrinkle resistance is poor; it is not easy to clean. Such as publication number: CN1103441, publication date: 1995.6.7, patent application number: 93114969.X, name: "Manufacturing method of lodging-resistant polypropyl...
