Embodiment 1

[0034] A method for producing a super-cotton-like shaped hollow textured yarn comprises the following steps:

[0035] Step 1: Mixing a polyester melt with an intrinsic viscosity of 0.62 dL / g into a polyester melt with an intrinsic viscosity of 0.62 dL / g and adding a fully matte polyester melt containing 50 wt % of titanium dioxide to obtain a blended polyester melt. The mass content of titanium dioxide in the ester melt is 2.0wt%;

[0036] Step 2: The blended polyester melt obtained in step 1 is measured by a metering pump, and then enters the spinning box through the spinning melt pipeline, and then passes through a 72-hole asymmetric hollow cross-section spinneret for extrusion, slow cooling and heating, and ringing. Blowing, cooling and solidifying, oiling and bundling, ultra-high-speed spinning, winding and doffing to obtain a full-dull special-shaped hollow filament, the hollowness of the full-dull special-shaped hollow filament is 30%, and the crystallization of the full...

Abstract

The invention discloses a production method of super-imitation cotton special-shaped hollow textured yarn, and belongs to the technical field of textured yarn production.The production method comprises the steps that full-dull polyester melt with 40-50 wt% of titanium dioxide is mixed into polyester melt in an online adding mode; the blended polyester melt is metered by a metering pump, extruded by a hollow special-shaped spinneret plate, slowly cooled and heated, cooled and solidified, oiled and bundled, spun at an ultra-high speed, wound and dotted to form a special-shaped hollow filament, and the special-shaped hollow filament is pre-drafted by a texturing machine, deformed by a friction disc, interlaced and wound to produce the super-imitation cotton special-shaped hollow textured yarn. According to the production method of the super-cotton-like profiled hollow textured yarn, the problem that the hollow-structure filament textured yarn cannot be obtained in the existing filament texturing technology is solved, the cross section form, the luster, the strength modulus and the like are close to the structural form and the mechanical property of cotton fibers, and meanwhile, the fibers are endowed with certain moisture conductivity; the defects of poor moisture absorption and stuffiness in wearing of polyester fabric are overcome, the defects of cotton fabric are overcome, and super cotton imitation is achieved.

Description

technical field [0001] The invention relates to the technical field of textured yarn production, in particular to a production method of a super-cotton-like shaped hollow textured yarn. Background technique [0002] In modern society, consumers prefer natural fibers such as cotton, wool, silk and linen textiles because natural fibers are comfortable to wear, have a natural feel, luster and appearance. Polyethylene terephthalate (PET fiber or polyester fiber) fiber is the largest synthetic fiber in textile materials. Polyester textile has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation properties, resistance to Sunlight, friction resistance, mildew and moth resistance, good chemical resistance, weak acid and weak alkali resistance, widely used in clothing, home textiles and other fields. [0003] However, polyester fiber textiles also have shortcomings such as excessive luster, unnatural appearance, poor moisture absorption, stu...
