Technical Field

The invention belongs to the technical field of fireproof fabrics, and relates to a fireproof composite fabric.

Background

The weaving principle is a general name taken from spinning and weaving, but with the continuous development and improvement of a weaving knowledge system and a subject system, particularly after non-woven textile materials, three-dimensional composite weaving and other technologies are produced, the weaving is not only traditional spinning and weaving, but also comprises a non-woven fabric technology, a three-dimensional weaving technology, an electrostatic nano-web forming technology and the like, so the modern weaving refers to a multi-scale structure processing technology of fibers or fiber aggregates. Ancient Chinese textile and printing and dyeing technology has a very long history, and ancient people have understood local materials, used natural resources as raw materials for textile and printing and dyeing and manufactured simple textile tools in order to adapt to climate change as early as the original society. Today, our everyday clothing, certain living goods and artwork are products of textile and printing and dyeing technology.

With the progress of production technology, various functional fabrics come out endlessly, which can meet the requirements of people on fabrics in different occasions, and especially the requirements on the functionality of the fabrics in special environments are stronger. The fireproof fabric can protect people from being injured under the crisis condition, but the common flame-retardant fabric can only resist flame, but has poor heat insulation and moisture permeability, and cannot better protect the personal safety of people in a fire scene.

Disclosure of Invention

The invention aims to provide a fireproof composite fabric, which solves the problem that the heat-insulating and moisture-permeable effects of a flame-retardant fabric in the prior art are poor.

The technical scheme adopted by the invention is that the fireproof composite fabric comprises an outer layer, an inner layer and a middle layer, wherein the outer layer, the inner layer and the middle layer are respectively formed by weaving warp yarns and weft yarns in an up-and-down staggered manner, and the outer layer, the inner layer and the middle layer are bonded by hot melt adhesive; the outer layer is a flame-retardant layer, the upper surface and the lower surface of the flame-retardant layer are sprayed with flame retardants, the inner layer is a moisture permeable layer, and the middle layer is a heat-insulating material.

The invention is also characterized in that:

the outer layer is formed by weaving warp yarns and weft yarns in an up-and-down staggered mode, the warp yarns comprise stainless steel fibers, polyester cotton, acrylic fibers and 20D chinlon delustering FDY filaments, the weft yarns comprise cotton, hemp, wool and 30D chinlon delustering FDY filaments, and the thickness of the single-layer outer layer is 1.2-1.5 mm.

The material of the intermediate layer comprises: expandable graphite, a phosphorus-or nitrogen-containing compound, and a foam base.

The inner layer is a blended fabric, and comprises the following components: 20-32% of ramie fibers, 6-20% of flax fibers, 10-15% of jute fibers, 10-13% of apocynum venetum fibers and 20-35% of polylactic acid fibers.
