Problems solved by technology

However, in actual production and application, the tensile degree of civil yarn is insufficient, the breaking strength is small, and the breaking elongation is large, which cannot meet the above requirements.
Polyester industrial yarn usually refers to industrial fibers above 600D, and the equipment of conventional industrial yarn production lines cannot spin 250D and below fine denier high-strength sewing threads

Abstract

The invention relates to a fine denier sewing thread purpose terylene industrial yarn and processing equipment thereof, and belongs to the fiber processing technical field; the fine denier sewing thread purpose terylene industrial yarn comprises a spinning manifold, a rear heater, a spinning channel, a drafting thermo forming mechanism and a coiling mechanism arranged from top to bottom in sequence; the spinning manifold comprises an outer box, an inner cylinder, a metering pump, a fuse tube and a spinning assembly; drafting thermo forming mechanism employs 5 roller pair mechanisms, wherein the first roller pair is cold roller; the second and third roller pairs are middle temperature rollers; the fourth roller pair is sub-high temperature roller; the fifth roller pair is high temperature roller; the processing equipment can control fineness of the sewing thread to be under 250D, breaking tenacity is above 6.8cN / dtex, and fracture percentage elongation is 15+-2%, thus fully satisfying sewing thread processing demands; the fine denier sewing thread purpose terylene industrial yarn and processing equipment can be applied to the protective clothing and insulation cover special fields.

Description

technical field [0001] The invention relates to a polyester industrial yarn for fine denier sewing thread and processing equipment thereof, belonging to the technical field of fiber processing. Background technique [0002] Sewing thread refers to the yarn used for sewing textile materials, plastics, leather products, and sewing books and periodicals. It has the characteristics of high strength, good wear resistance, creep resistance, and good weather resistance. It must meet the requirements of seamability and durability. Requirements for performance and appearance quality. However, in actual production and application, the stretchability of civil yarn is insufficient, the breaking strength is small, and the breaking elongation is large, which cannot meet the above requirements. Polyester industrial yarn usually refers to industrial fibers above 600D, and the equipment of conventional industrial yarn production lines cannot spin 250D and below fine denier high-strength sew...
