Embodiment 1

[0021] High temperature resistant cut-resistant composite yarn, including a central fiber as the inner core and a sheath fiber that is twisted and entangled with the central fiber and wrapped around the central fiber, that is to say, the high temperature resistant fiber described in this embodiment The cut-resistant composite yarn is composed of two components or components, a central fiber as the inner core and a sheath fiber combined with the central fiber and located outside the central fiber. The mass percentage of the central fiber in the composite yarn is 30%, and the mass percentage of the covering fiber in the yarn is 70%. The central fiber uses high-strength chemical fiber filaments with a strength of 2.1N / dtex and a fineness of 55dtex. This high-strength chemical fiber filament is obtained by spinning polyester chips, wherein: polyester chips are added with 2.5% by weight of nano-titanium dioxide with a Mohs hardness greater than grade 3 and a particle size of 0.25...

Embodiment 2

[0024] Only the mass percentage of the central fiber in the composite yarn is changed to 70%, and the mass percentage of the covering fiber in the composite yarn is changed to 30%. The central fiber uses a strength of 3cN / dtex and a denier of 330dtex glass fiber yarn, the covering fiber is aramid staple fiber with a denier of 3.2dtex, a length of 100mm and a strength of 17.57cN / dtex. The technical instructions of the high temperature and cut-resistant composite yarn with a specification of 10S are shown in Table 1. shown. All the other are the same as the description to embodiment 1.

Embodiment 3

[0026] Only change the mass percentage of the central fiber in the composite yarn to 50%, and change the mass percentage of the covering fiber in the composite yarn to 50%, and the central fiber uses a strength of 2.8cN / dtex and denier It is a high-strength chemical fiber filament of 75dtex, and the high-strength chemical fiber filament is obtained by spinning polyamide chips, that is, PA66 chips, wherein: 4% by weight of Mohs hardness is added to the polyamide chips Nano silica (similar other inorganic particles can also be used) that is greater than grade 3 and has a particle size of 0.3-3 μm. The covering fiber is aramid staple fiber with a denier of 2.8dtex, a length of 38mm and a strength of 18.01cN / dtex. The technical instructions for obtaining a high-temperature-resistant and cut-resistant composite yarn with a specification of 40S are shown in Table 1.

Abstract

The invention relates to a high-temperature resistant cutting preventing composite yarn and the application of the high-temperature resistant cutting preventing composite yarn, belonging to the technical field of special yarn. The high-temperature resistant cutting preventing composite yarn comprises a central fiber and a coated fiber, wherein the central fiber is used as an inner core, and the coated fiber is formed by twisting, winded with the central fiber and coated outside the central fiber. The high-temperature resistant cutting preventing composite yarn is characterized in that the central fiber is the chemical filament and accounts for 30-70% by mass of the composite yarn, the coated fiber is the short aramid fiber 1414 and accounts for 70-30% by mass of the composite yarn. The high-temperature resistant cutting preventing composite yarn integrates the outstanding high-temperature resistance and fire resistance of the short aramid fiber 1414 and the advantage of excellent cutting-preventing performance of the chemical filament, and the fabric made of the high-temperature resistant cutting preventing composite yarn by processing can be used in the high-temperate and sharp work environment. The high-temperature resistant cutting preventing composite yarn is safe and durable.

Description

technical field [0001] The invention belongs to the technical field of special yarns, and in particular relates to a high-temperature-resistant and cut-resistant composite yarn, and also relates to the application of the yarn. Background technique [0002] At present, protective products made of asbestos fiber-based composite yarns are generally used in typical high-temperature occasions such as steel manufacturing industry and sharp working conditions (working environment) such as glass product manufacturing industry. Although asbestos has the advantages of good high temperature resistance, friction resistance, low price, light specific gravity, low thermal conductivity (0.198-0.244W〈m·k〉) and low electrical conductivity, however, asbestos is carcinogenic to the human body As well as polluting the environment, the production and use of asbestos products, including protective equipment, is increasingly restricted, and even banned in many economically developed countries and ...
