Embodiment 1

[0027] In the high temperature resistant composite glass fiber sewing thread of this embodiment, the diameter of the glass fiber monofilament 1 is 3.8 μm; the diameter of the metal wire 2 is 20 μm, the elongation is 2.8%, and the tensile strength is 500 MPa.

[0028] The preparation method of the high temperature resistant composite glass fiber sewing thread of the present embodiment comprises the following steps:

[0029] (1) Glass fiber monofilament 1 is drawn and treated with soaking emulsion at the same time to form impregnated layer 4, which is directly treated by raw silk and spun into yarn through the de-solution process;

[0030] (2) the yarn after the solution and the metal wire 2 are plied through the parallel twisting process, and twisted to make the required composite glass fiber sewing thread;

[0031] (3) The composite glass fiber sewing thread described in step (2) is impregnated with the mixed solution, then dried in a pre-dryer, and finally sintered in a sinte...

Embodiment 2

[0036] In the high temperature resistant composite glass fiber sewing thread of this embodiment, the diameter of the glass fiber monofilament 1 is 5.5 μm, the diameter of the metal wire 2 is 10 μm, the elongation is 1.5%, and the tensile strength is 800 MPa.

[0037] The preparation method of the high temperature resistant composite glass fiber sewing thread of the present embodiment comprises the following steps:

[0038] (1) Glass fiber monofilament 1 draws and carries out soaking emulsion treatment simultaneously, forms impregnation layer 4, adopts raw silk to directly process, and is spun into yarn through desolation process;

[0039] (2) the yarn after the solution and the metal wire 2 are plied through the parallel twisting process, and twisted to make the required composite glass fiber sewing thread;

[0040] (3) The composite glass fiber sewing thread described in step (2) is impregnated with the mixed solution, then dried in a pre-dryer, and finally sintered in a sint...

Abstract

The invention provides a heat-resistant complex glass fiber sewing thread which has high tensile strength, thermostability, good corrosion resistance, static resistance, low production cost and long service life, and a preparation method thereof so as to meet the using requirements of a sewing thread in environments with high temperature, strong corrosive performance, large static electricity, and the like. The heat-resistant complex glass fiber sewing thread comprises a plurality of glass fiber monofilaments and at least one metal filament which are twisted together, a sintered layer is arranged on the surface of the heat-resistant complex glass fiber sewing thread, and an impregnated layer is arranged on the surface of each glass fiber monofilament. The impregnated layer and the sintered layer can improve the flexibility, the folding resistance, the wear resistance, the corrosion resistance and the like of the crude filaments and the sewing thread.

Description

technical field [0001] The invention relates to a high-temperature-resistant sewing thread and a preparation method thereof, in particular to a high-temperature-resistant composite glass fiber sewing thread and a preparation method thereof. [0002] Background technique [0003] Glass fiber sewing thread is widely used in sewing high temperature resistant fabrics, dust filter bags, electrical insulation materials, heat insulation materials, cable fillers, fireproof materials, wicks, seals, winding heating wires and heating elements, etc. [0004] Especially in the processing of environmental protection dust removal filter bags, glass fiber sewing thread can be used to sew various filter bags on industrial high-speed sewing machines; to sew acid-resistant, alkali-resistant and other corrosion-resistant fabrics. It can be used for a long time at 260°C, and can meet the needs of seaming filter bags in steel, carbon black, metallurgy, cement and other industrial sectors. [000...
