Abstract

The application relates to the technical field of automotive interiors, and particularly discloses a high-flame-retardance wool blended fabric for automotive interiors, which is woven by warp yarns and weft yarns; the warp yarns are formed by blending polyester fibers, modified wool fibers and bamboo fibers; the weft yarns are formed by blending polyester fibers, modified wool fibers and carbon fibers; the modified wool fiber is prepared from the following raw materials in parts by weight: 60-100 parts of wool fiber, 10-15 parts of dopamine hydrochloride, 3-5 parts of tris (hydroxymethyl) aminomethane, 20-30 parts of flame retardant, 8-12 parts of antistatic agent and 3-5 parts of penetrating agent; the wool blended fabric has the advantages of simple formula and strict proportion, has excellent flame retardant property, greatly improved mechanical property, antibacterial and antistatic properties, and has wide application prospect in the field of automotive interiors.

Description

High-flame-retardance wool blended fabric for automotive interiors
Technical Field
The application relates to the technical field of automotive interiors, in particular to a high-flame-retardance wool blended fabric for automotive interiors.
Background
Wool fiber is a natural protein fiber, has special structure and chemical composition and characteristics and advantages which are not available in various synthetic fibers, and especially contains a large amount of nitrogen and sulfur elements, has self-extinguishing performance and can self-extinguish after leaving fire. Wool fiber is used as a main component material of automobile interior trim in a self-comfort skin-friendly property and self-extinguishing property, but because the mechanical property of the wool fiber is poor and is easy to wear, the wool fiber needs to be blended with other synthetic fibers to prepare automobile seat jackets and carpets, so that the automobile interior trim can be effectively ensured to have excellent comfort, heat preservation, ventilation and moisture absorption properties, and also has excellent mechanical property and durability.
Although wool fibers have good self-extinguishing properties compared with other fibers, wool fibers still belong to the category of flammable textiles, most synthetic fibers have flammable characteristics, and a molten drop phenomenon can be generated during combustion, so that a 'candlewick effect' can be generated during combustion of wool blended fabrics, and larger fire hazards are easily caused. Therefore, it is highly needed to provide a high-flame-retardance wool blended fabric for automobile interiors, so as to solve the problem that the flame retardance of the existing wool blended fabric is not strong, greatly improve the flame retardance of the wool blended fabric, and better meet the high-performance requirements of the automobile interiors.
