Embodiment

[0026] The present invention adopts warp yarn 14.5tex * weft yarn 14.5tex, 100% polyimide yarn, warp density 120 per inch * weft density 90 per inch, width 152-154 centimeters, plain weave tooling fabric, the fabric is soaked Roll the pre-treatment liquid with strong hydrophilicity and hygroscopicity, and then carry out digital printing of nano-coating ink on the front and back sides, drying, baking and setting, and produce high flame-retardant, multi-color tooling fabrics, ignition 6 It can't burn in minutes, and the flame-retardant effect reaches the level of incombustibility. It is suitable for the functional requirements of clothing in special protective industries such as firefighting, steelmaking, and forest firefighting.

Abstract

The invention discloses a method of dyeing a high-flame-retardant tooling fabric. The method comprises the steps of acquiring a gray fabric, pretreating the gray fabric, dyeing the front, drying for the first time, baking, dyeing the back, drying for the second time, baking, packaging the finished fabric, and detecting. A tooling fabric with plain weave having a warp density of 120 per inch, a weft density of 90 per inch and a breadth of 152-154 cm is woven with 100% polyimide yarns having warps 14.5 tex and wefts 14.5 tex; the tooling fabric is padded with a highly hydrophilic and hydroscopicpretreating liquid, subjecting the front and back to all-over digital printing with nano coating ink, drying, baking to shape to obtain a high-flame-retardant variable-color tooling fabric. The high-flame-retardant tooling fabric herein never burns even after being ignited or 6 min, the flame-retardant level reaches incombustibility level, and the high-flame-retardant tooling fabric is suitable for satisfying the function requirements of special protective garments for the industries, such as firefighting, steelmaking, and forest firefighting.

Description

technical field [0001] The invention belongs to the field of fabrics in the textile industry, and in particular relates to a method for dyeing highly flame-resistant tooling fabrics. Background technique [0002] Polyimide fiber has high strength, high modulus and high temperature resistance. It is an important high-performance fiber. Its molecular main chain contains imide ring groups, referred to as PI fiber. At present, there are mainly Gaoqi Polyimide Materials Co., Ltd. in Changchun, Jilin Province and Aoshen New Materials Co., Ltd. in Lianyungang, Jiangsu Province that can carry out large-scale and industrialized production of polyimide fibers in China. Based on the excellent properties of high temperature resistance, flame retardancy, mechanical and chemical resistance, polyimide fiber has become one of the hot materials for producing safety protection products such as heat insulation and fire protection, and is favored by the market. However, the polyimide fiber its...
