Embodiment 1

[0047] A waterproofing agent, which is made by polymerization reaction of 28 parts of organosilicon monomer, 13 parts of organic fluorine monomer, 13 parts of modified nano-silica sol, 8 parts of emulsifier, 0.8 parts of initiator and 163 parts of water. The preparation method as follows:

[0048] Add 140 parts of water, 13 parts of modified nano-silica sol and 8 parts of emulsifier into the reaction kettle, dissolve and stir to disperse evenly, then add 12 parts of organosilicon monomer (as shown in the above formula 2), stir and emulsify for 0.5h ;When the temperature reaches 78°C, add a solution of 0.3 parts of initiator and 8 parts of water, and keep warm for 0.5h; add dropwise a solution of 0.5 parts of initiator and 15 parts of water, 16 parts of organic silicon monomer, 13 parts of organic fluorine monomer After 2 hours of dripping, the temperature was raised to 85°C, and the reaction was continued for 1 hour, and then the temperature was lowered to below 50°C to obtain...

Embodiment 2

[0063] A composite multifunctional fabric with a foaming breathable film, which includes a surface fabric, an adhesive layer, a foamed film, an adhesive layer, and an inner fabric from top to bottom. The surface of the surface fabric is also provided with a waterproof agent, fabric and film Composite by adhesive layer;

[0064] The method for preparing foamed breathable film composite multifunctional fabric is as follows:

[0065] ① Prepare the waterproofing agent and water to form a 30g / L waterproofing agent finishing solution,

[0066] ②The surface fabric is dipped and rolled with waterproofing agent finishing liquid, two dipping and two rolling, the rolling rate is 80%

Abstract

The invention discloses a foaming breathable film composite multifunctional fabric which comprises a surface layer fabric, a bonding layer, a foaming film, a bonding layer and an inner layer fabric from top to bottom. The fabric and the film are compounded through the bonding layer, and a waterproof agent is further arranged on the surface of the surface layer fabric. The preparation method of thefoaming breathable film composite multifunctional fabric comprises the following steps: (1) preparing a waterproofing agent finishing liquid from the waterproofing agent and water; (2) padding the surface layer fabric in the waterproofing agent finishing liquid; (3) drying and baking; (4) coating the surface layer fabric and an inner layer fabric with a binder, and compounding with the foaming film; and (5) drying and baking.

Description

technical field [0001] The invention relates to a composite functional fabric, in particular to a foamed breathable membrane composite multifunctional fabric, which belongs to the field of functional textiles. Background technique [0002] Waterproof and moisture-permeable fabric is usually also called waterproof and breathable fabric, which is a fabric that can not only prevent rain and wind, but also wick away sweat and breathe. During the wearing process, water cannot penetrate the fabric under a certain pressure, but the sweat emitted by the human body can be transmitted to the outside world through the fabric in the form of water vapor, without condensation and accumulation between the human body surface and the fabric, keeping the wearer dry and warm. Most of the waterproof and moisture-permeable functional fabrics are high-density fabrics, coated fabrics, and laminated fabrics. In terms of processing convenience and performance, laminated fabrics account for the majo...
