Normal temperature and pressure dyeable polyester carpet yarn

Abstract

The invention relates to normal temperature and pressure dyeable polyester carpet yarn belonging to the technical field of carpet yarn. The invention is characterized that the normal temperature and pressure dyeable polyester carpet yarn is prepared by twisting 300D modified polyester texturing filaments or 200D modified polyester texturing filaments, adopts a first technical scheme by once doubling two 300D modified polyester texturing filaments into one, twisting S, twice doubling two pieces of twisted yarn into one and twisting Z, a second technical scheme by once doubling four 300D modified polyester texturing filaments into one, twisting S, twice doubling two pieces of twisted yarn into one and twisting Z, and a third technical scheme by once doubling two 200D modified polyester texturing filaments into one, twisting S, twice doubling two pieces of twisted yarn into one and twisting Z. The invention can dye at normal temperature and pressure so as to save energy consumption; high dye utilization rate and color fastness are achieved; and a textured carpet has soft foot feeling and good crease resistance.

Description

technical field [0001] The invention belongs to the technical field of carpet yarns, in particular to a normal temperature and pressure dyeable 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, it cannot be dyed under normal temperature and pressure, so the energy consumption in the dyeing process is large; second, the dye utilization rate and color fastness are low; third, the woven carpet feels poor. Soft; poor wrinkle resistance. Such as publication number: CN1103441, publication date: 1995.6.7, patent application number: 93114969.X, name: "Manufacturing method of lodging-resistant polypropylene BCF carpet yarn"; publication number: CN119253, publication da...
