The influence of cross-linking agent on waterproof and oil-proof finishing processing
Dilute the fluoropolymer emulsion fabric water-blocking agent (AG-7500) to 2-5%, add an appropriate amount of cross-linking agent, pad the fabric in the bath, and then use a general roller to remove excess liquid. The remaining rate is is about 70%. Pre-bake for 2 minutes, and then bake for 1 minute at a high temperature of 160-170 degrees. After moisture regain, evaluate the various properties of the fabric. Water repellency, oil repellency, and water resistance
We did experiments with baking times of 30 seconds and 1 minute, experiments with dosages of 2%-5%, and experiments with and without the addition of cross-linking agents.
The results show that the baking time has a greater impact on the oil and water repellent properties of the finished fabric. If the baking time is too short, the reaction between the cross-linking agent, the finishing agent and the fabric fibers is incomplete, resulting in a reduction in the oil and water repellent properties, and vice versa. , the baking time will damage the fabric fibers. Generally, the temperature is 160-170 degrees and the baking time is one minute. When the cross-linking agent is added, the wash resistance is better than that without the cross-linking agent. a little.
Choose a suitable, cost-effective water-blocking agent (such as AG-7500, AG-710 and other water-blocking agents) plus a reasonable process prescription, and your fabrics will surely have competitive water- and oil-repellent properties. A powerful dark horse fabric company.
