Problems solved by technology

With the expansion of the use of polyester industrial yarn, higher requirements are put forward for the effect of polyester industrial yarn fabrics, and the existing product structure can not meet the needs of the market. The section of the polyester industrial yarn is circular, so there is a large gap between the whole tow and the yarn, which has a great influence on the cohesion of the polyester industrial yarn and the flatness of the cloth surface after weaving into the final fabric.

Abstract

The invention discloses a specially-shaped industrial yarn, a production method thereof and a special spinneret, and belongs to the field of textile technology. The specially-shaped industrial yarn produced by changing the spinneret and optimizing the industrial yarn production process has a cross section similar to rectangular shape and has greatly improved cohesive property on the basis of keeping the advantages of common industrial yarn without special process. The cross section similar to rectangular shape ensure small clearance between yarns, large contact area, more flat and compact arrangement, and larger friction between yarns, so that single yarn is not easy to be dispersed under the condition of not increasing oil, etc. and can prevent the generation of defects caused by the dispersion of the single yarn after the friction of a yarn guide, etc. in back-end spinning process. Meanwhile, the light beams can be diffusively reflected on the fiber surface, so that the fiber has larger light absorption than light reflection and the yarn has better glossiness and aesthetic degree than normal round yarn.

Description

technical field [0001] The invention provides a special-shaped industrial yarn, its production method and a special spinneret, belonging to the technical field of textiles. Background technique [0002] Polyester industrial yarns such as polyester, nylon, and polypropylene yarns are used as the main raw materials for industrial chemical fibers. They are widely used due to their high strength, good mechanical and chemical stability, wear resistance, and corrosion resistance. Tire cord fabrics, conveyor belts, V-belts, sandwich fabrics, geotextiles and other fields. With the expansion of the use of polyester industrial yarn, higher requirements are put forward for the effect of polyester industrial yarn fabrics, and the existing product structure can not meet the needs of the market. The section of the polyester industrial yarn is circular, so there is a large gap between the whole tow and the yarn, which has a great influence on the cohesion of the polyester industrial yarn ...
