Abstract

The invention relates to a label fabric, in particular to a label fabric prepared from regenerative nylon grains. The label fabric comprises a base cloth layer and gluing layers coating the upper surface and the lower surface of the base cloth layer, wherein the base cloth layer is regenerative nylon base cloth prepared from regenerative nylon grains through melt spinning and warping weaving; during weaving, the regenerative nylon grains are spun to form single stranded yarns which are used as warp silk, and the density of the warp silk is 40-50 per centimeter; multiple stranded synthetic fiber yarns are used as weft silk; the viscosity of a gluing material of at least one of the upper and lower gluing layers is 1200-1800 cps; the sizing material is prepared from the following components in parts by weight: 40-60 parts of methyl alcohol, 20-30 parts of calcium chloride, 10-20 parts of regenerative nylon grains, 10-20 parts of filler, and 0.06-0.1 part of a whitening agent. According to the label fabric, the new application of the regenerative nylon grains is expanded, and the resource regeneration utilization is achieved really; a desizing assistant causing environment pollution is not used, and a solvent suitable for recycling is adopted to achieve a good environment protection effect.

Description

technical field [0001] The invention relates to a trademark cloth, in particular to a trademark cloth made of regenerated nylon particles. Background technique [0002] Lack of resources and pollution are common problems faced by the world today; on the one hand, the world's textile industry has a shortage of raw materials with the increasing population, and its price has risen sharply; on the other hand, a large amount of textile waste such as The leftovers from the production process, waste yarn, waste cloth, used old clothes and other textiles are often used to wipe oily equipment and parts or clean the floor, or buried, which wastes resources and causes pollution, and the scope of reuse is small. From the perspective of ecological security and environmental protection, advocating resource conservation, circular economy and low-carbon economy, as well as the concept of green products and green consumption has become the mainstream of society. According to authoritative r...
