Problems solved by technology

After scraping and applying the adhesive, the most direct impact is that the fabric feels hard, which affects the comfort of the final product
2. Because the flame retardancy of this fabric mainly comes from the adhesive material, and the flame retardancy of the adhesive material comes from the flame retardant added in it, and most of the flame retardants on the market do not meet the environmental protection standards
If the back glue is not completely dry, the back glue will stick to the surface of the fabric during the rolling process, resulting in defective fabrics
If the final adhesive is too dry, it will easily fall off and feel harder
However, the way of scraping and coating the back glue is itself unstable, and the drying on this basis is even without standards, resulting in large deviations in the quality of the final product

Embodiment 1

[0028] A production process of flame-retardant composite cloth, comprising the following steps:

[0029] S1. Processing of flame retardant cloth:

[0030] a, acrylic fiber is modified: utilize treatment liquid to carry out dip-dyeing to acrylic fiber, the liquid ratio of dipping is 1:20, the temperature of dipping is 40 ℃, and dipping time is 40 minutes; The content of cyanohydrolase in the processing liquid and The weight ratio of the acrylic fiber is 3:50; after the dip-dyeing is completed, dry at a temperature of 40-45° C. to obtain the modified acrylic fiber;

[0031] b. Mixing modified acrylic fibers with acrylic pre-oxidized yarns to obtain mixed fibers, wherein the modified acrylic fibers account for 60% by weight, and the mixed fibers are processed into non-woven fabric flame-retardant cloth, knitted fabric flame-retardant cloth, etc. Flame-retardant cloth or woven cloth;

[0032] S2, dyeing and drying the flame-retardant cloth;

[0033] S3. Composite molding: compo...

Embodiment 2

[0035] Compared with Example 1, the difference is that the modified acrylic fiber accounts for 65% by weight in the mixed fiber.

Embodiment 3

[0037] Compared with Example 1, the difference is that the modified acrylic fiber accounts for 70% by weight in the mixed fiber.

[0038] The flame-retardant composite fabric prepared by the process of the invention not only has good flame-retardant performance, but also has excellent hand feeling. The environmental protection is better than the post-treatment method of adhesive, which solves the defects caused by the traditional drying of adhesive, and has achieved excellent market evaluation.

[0039] In the composite process of flame-retardant cloth and face cloth, because the flame-retardant cloth and face cloth have a certain width, the traditional glue spraying method is adopted, and the glue spraying force close to the center of the glue spraying port is large, resulting in a large amount of glue. The glue spraying force near the edge of the glue spray port is relatively small, resulting in a small amount of glue. In the end, the partial composite reliability of the pr...

Abstract

The invention relates to the field of home furnishing fabrics, and aims to provide a production technology of a flame-retardant composite fabric. The flame-retardant composite fabric with excellent hand feeling, environmental protection and stable quality can be processed through the production technology. The production technology of the flame-retardant composite fabric comprises the following steps: S1, processing of a flame-retardant fabric: a, modifying of acrylic fibers: dip dyeing of the acrylic fibers with a treatment liquid at a dip dying liquor ratio of 1:20 at 40 DEG C for 40 min; and b, mixing of 60-70 wt% of the modified acrylic fibers with pre-oxidized acrylic fibers to obtain mixed fibers, and processing of the mixed fibers to form a nonwoven flame-retardant fabric, a knittedflame-retardant fabric or a woven flame-retardant fabric. The flame-retardant fabric makes the product have good flame retardancy and excellent hand feeling.

Description

technical field [0001] The invention relates to the field of home decoration fabrics, in particular to a production process of flame-retardant composite fabrics. Background technique [0002] At present, in order to make home decoration fabrics meet the flame retardant requirements of British standard BS5852 and cruise ship IMOpart8, it is mainly achieved by scraping thick acrylic backing with flame retardant additives on the back of the fabric. However, the flame-retardant fabrics for home decoration processed in this way still have the following disadvantages: 1. The weight of the acrylic adhesive colloid of general flame-retardant additives is generally 100 g / square or even heavier, and the specific value is different from that of the fabric. Composition, grammage and organization are relevant. After scraping and applying the adhesive, the most direct impact is that the fabric feels hard, which affects the comfort of the final product. 2. Because the flame retardancy of...
