Abstract

The invention discloses a processing method of waterproof flame-retardant composite plain cloth. The processing method comprises steps of: a step of interweaving Corterra yarn and PET yarn to obtain composite plain cloth; a step of adding the composite plain cloth in a solution mixture of a flame retardant and water, heating for 20 min, and maintaining the temperature for 10 min; a step of taking the composite plain cloth out from the solution mixture and drying; and a step of adhering the composite plain cloth and TPU film through a polyurethane (PU) adhesive. The process is simple and easily understood. The produced plain cloth is full in color, comfortable in handfeel, elastic, good in heat resistance, good in corrosion resistance, durable, and largely improved in waterproofness, air permeability and damp permeability, and can maintain good performances after being washed in water or 60-70 times.

Example Embodiment

[0012] Example
[0013] The processing method of the waterproof and flame-retardant composite flat cloth of the present embodiment comprises the following specific steps: firstly, interweaving high telon yarn and PET yarn into composite flat cloth; putting the composite flat cloth into a solution containing a flame retardant mixed with water Inside, after heating for 20 minutes, keep warm for 10 minutes; then take out the composite flat cloth from the solution and dry it; finally, bond the composite flat cloth with TPU film through polyurethane PU glue.
[0014] The percentage by weight of each component of the polyurethane PU glue is: 100 parts of polyurethane adhesive, 44 parts of solvent, 44 parts of solvent toluene, 0.51 part of bridging agent, 15 parts of curing agent, and the polyurethane adhesive is adipic acid: Phthalic acid: ethylene glycol: neopentyl glycol = 1:1:1.7:0.3 The ratio of synthetic polyester diol and diisocyanate is prepared as the main raw material, and the curing agent is a component of free isocyanate groups , The bridging agent is a multifunctional prepolymer of trihydroxypropane and TDI. The thickness of the TPU film bonded with the composite plain cloth is: 0.015mm. The flame retardant is a halogen-free high-efficiency organic nitrogen and phosphorus compound.
[0015] The process is simple and easy to understand, and the flat cloth produced is full of color, comfortable to the touch, elastic, has good heat resistance, corrosion resistance, durability, waterproof, breathable and moisture permeability have been greatly improved, and the number of washing times has reached 60- After 70 times, it can still maintain good performance.
