Problems solved by technology

[0003] (1) Due to the unreasonable treatment of the base fabric and the unreasonable control of the coating process, the shrinkage of the coated fabric is greater than 3% after a period of time at room temperature, and the product seam slippage is greater than 3mm, which does not meet the user's requirements
[0004] (2) Commonly used shading and flame-retardant coatings contain a variety of heavy metal ions and toxic substances exceeding the standard for formaldehyde

Abstract

The invention discloses a preparation method of a terylene light-shielding flame-retardant coated fabric. The preparation method is carried out according to the following flow of: fabric pre-shrinking, fabric padding pretreatment agent drying, base coating drying, light-shielding layer coating drying and surface color coating drying, wherein in the fabric pre-shrinking process, a pre-shrinking setting speed is reduced to 20m/min from 40m/min, a pre-shrinking temperature is risen to 200 DEG C from 150 DEG C, and an effective width of 150cm of a base fabric before pre-shrinking is reduced to aneffective width of 146cm after pre-shrinking; an assistant water-soluble flame-retardant pretreatment agent is selected to carry out padding on the fabric, coating agents are compositely coated and scraped on the base fabric, the coating agents sequentially comprise three coating agents of a PA emulsion, a flame retardant and silver colloid, and finally, the fabric enters a drying oven in a completely relax state to be set. Proper environmental-friendly glue is selected, so that the problem of environmental protection is solved. The pre-shrinking setting speed and the pre-shrinking temperaturein the fabric pre-shrinking process are controlled, so that problems of size stability and seam slippage are solved, shrinkage control is smaller than 1%, and seam slippage is smaller than 2%.

Description

technical field [0001] The invention relates to a flame-retardant curtain fabric, in particular to a preparation method of a polyester light-shading flame-retardant coating fabric. Background technique [0002] Fabric finishing can not only endow textiles with aesthetic effects, but more importantly, special effects. Functional finishing technology can protect textiles from various adverse environmental influences, such as harsh climate, microorganisms or bacteria, high temperature, chemicals (such as acids, alkalis and organic solvents), and mechanical abrasion. At present, shading and flame-retardant coated fabrics are less produced in the market, and the production process has not yet been perfected. The main common problems are the following technical difficulties in the production process: [0003] (1) Due to the unreasonable treatment of the base fabric and the unreasonable control of the coating process, the shrinkage rate of the coated fabric is greater than 3% afte...
