Embodiment 2

[0034] The waterproof fabric of step 3 in embodiment 2 is done waterproof treatment and the processing mode of embodiment 1 is identical, comprises the following steps:

[0035] A. Add osmotic agent in warm water with a temperature of 30-40 degrees Celsius and stir evenly. The amount of osmotic agent is calculated by mass as 2-3 grams of osmotic agent per kilogram of warm water. In actual operation, 2.5 grams per kilogram can be added. or 2.3 grams, wash and dry the waterproof fabric treated in the previous step 1 and 2 in warm water;

[0036] B, in the warm water that temperature is 35-50 degree Celsius, add cross-linking agent, waterproofing agent and glacial acetic acid and stir evenly, wherein cross-linking agent and waterproofing agent add first, glacial acetic acid adds last, described cross-linking agent, waterproofing agent and The dosage of glacial acetic acid is calculated by mass as 8-15 grams of cross-linking agent, 80-120 grams of waterproofing agent and 3-5 grams...

Abstract

The invention discloses a waterproof fabric, which is characterized by comprising a fabric layer, a middle layer and a waterproof cloth layer, and the inner side face of the fabric layer and the outerside face of the middle layer are coated with a water-based glue and then bonded through an oil-based glue; the inner side face of the middle layer and the outer side face of the waterproof cloth layer are coated with water-based glue and then bonded through the oil-based glue. The invention further provides a waterproof treatment process of the waterproof fabric. According to the waterproof fabric and the process thereof, the cost is lower, and the waterproof performance can be ensured on the premise that the bonding firmness and the air permeability are ensured.

Description

technical field [0001] The invention relates to a waterproof fabric. The invention also relates to a waterproof treatment process for the waterproof fabric. Background technique [0002] The existing waterproof fabric includes a woven waterproof fabric of the outer layer, an adhesive layer of the middle layer and an inner waterproof fabric of the inner layer bonded to each other, the woven waterproof fabric is made of a high elastic material, and the inner waterproof fabric is made of a low elastic material made, the woven tarpaulin and the inner tarpaulin are bonded by means of a melted adhesive layer. However, the cost of the traditional adhesive layer is high, and the adhesion is greatly affected by temperature, and it does not help the waterproof performance much. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a waterproof fabric, which has lower cost and can ensure waterproof performance under the premise...
