Embodiment 1

[0032] refer to figure 1 , a preparation method of fire-resistant and heat-insulating sewing thread, comprising the following steps:

[0033] S1: Make the base layer of flame-retardant sewing threads, and use water-soluble polyvinyl alcohol fibers as raw materials to make sewing threads of different yarn counts and thicknesses;

[0034] S2: Inspection, random inspection of the sewing thread, testing its elongation at break, the elongation at break of the sewing thread is between 50-80% is qualified, otherwise it is unqualified, and the unqualified rate is greater than 8%, then discuss whether the analysis process has problem, and to detect it, through the detection steps to ensure that the elongation at break of the sewing thread is within the acceptable range and improve its quality;

[0035] S3: dyeing, the sewing thread is continuously fed, and the sewing thread is dipped in a coloring solution containing ultraviolet curable resin, photopolymerization initiator, pigment an...

Embodiment 2

[0043] S1: Make the base layer of flame-retardant sewing threads, and use water-soluble polyvinyl alcohol fibers as raw materials to make sewing threads of different yarn counts and thicknesses;

[0044] S2: Inspection, random inspection of sewing thread, testing its elongation at break, the elongation at break of sewing thread is between 50-80% is qualified, otherwise it is unqualified, if the unqualified rate is greater than 10%, discuss whether the analysis process has problem, and to detect it, through the detection steps to ensure that the elongation at break of the sewing thread is within the acceptable range and improve its quality;

[0045] S3: dyeing, the sewing thread is continuously fed, and the sewing thread is dipped in a coloring solution containing ultraviolet curable resin, photopolymerization initiator, pigment and organic solvent for dyeing treatment;

[0046] S4: Drying and shaping, high temperature drying and shaping of the sewing thread;

[0047] S5: Make...

Embodiment 3

[0053] S1: Make the base layer of flame-retardant sewing threads, and use water-soluble polyvinyl alcohol fibers as raw materials to make sewing threads of different yarn counts and thicknesses;

[0054] S2: Inspection, random inspection of sewing thread, testing its elongation at break, the elongation at break of sewing thread is between 55-70% is qualified, otherwise it is unqualified, if the unqualified rate is greater than 10%, discuss whether the analysis process has problem, and to detect it, through the detection steps to ensure that the elongation at break of the sewing thread is within the acceptable range and improve its quality;

[0055] S3: dyeing, the sewing thread is continuously fed, and the sewing thread is dipped in a coloring solution containing ultraviolet curable resin, photopolymerization initiator, pigment and organic solvent for dyeing treatment;

Abstract

The invention relates to the technical field of sewing thread processing, and discloses a preparation method of a fire-resistant and heat-insulation sewing thread. The method comprises the following steps of S1, preparing a flame-retardant sewing thread base layer: preparing sewing threads with different yarn counts and different thicknesses from water-soluble polyvinyl alcohol fibers as raw materials; S2, performing detection: carrying out casual inspection on the sewing threads, detecting the breaking elongation of the sewing threads, if the breaking elongation of the sewing threads is between 50% and 80%, determining that the sewing threads are qualified, otherwise, determining that the sewing threads are unqualified, and if the reject ratio is greater than 10%, discussing and analyzing whether the process has problems or not, and detecting the sewing threads; and S3, performing dyeing: feeding the sewing threads continuously. The sewing thread not only has a flame-retardant effect, but also can improve the fire resistance and heat insulation performance, and has the skin-friendly and sweat-absorbing characteristics, and the manufactured sewing thread has the antistatic performance, so that the functional diversity of the sewing thread is improved; and singeing is conducted through a singeing roller after drying, so that the surface smoothness of the sewing thread can be improved, and the sewing thread is more attractive and durable.

Description

technical field [0001] The invention relates to the technical field of sewing thread processing, in particular to a preparation method of fire-resistant and heat-insulating sewing thread. Background technique [0002] Sewing thread refers to the thread used for sewing textile materials, plastics, leather products and sewing books and periodicals. Sewing thread is characterized by sewability, durability and visual quality. Sewing threads are generally divided into three types due to their different materials: natural fiber type, chemical fiber type, and mixed type. The characteristics of sewing thread also have its unique properties due to its different materials. [0003] The polyester sewing thread is obtained by co-twisting specific polyester yarns including a plurality of polyester filaments, and bonding the polyester yarns by internal bonding, external bonding, or internal and external bonding. Polyester fibers with high tenacity, moderate elongation and dry heat shri...
