Some manufacturers say that after being treated by our company (), the waterproof effect is 100% and there is no penetration at all; however, after the yarn is rubbed by the metal sheet of the sewing machine, the waterproof effect tends to be halved. Regarding this phenomenon, our company The solution provided by the technical department staff is to slightly increase the dosage based on the original dosage, so that the friction on the yarn will be improved;
It should be noted here that after the yarn or fabric is waterproofed, a waterproof layer is formed on the surface of the fabric. If it undergoes a large amount of friction, the waterproof effect will definitely be affected, but the degree of impact is different; because The waterproof covering layer formed on the surface of the fabric is relatively weak, and as long as there is no significant friction, it will basically have no effect on the waterproofing effect.
