Today we are going to talk about the matters needing attention in the use of zippers. Let me tell you about the precautions for the use of zippers. 1. Nylon zipper is used for pvc fabric or waterproof/ski fabric (light color), please note that the fabric will absorb the oil stains in the zipper and cause the fabric to be stained. When accepting similar orders, please specify when placing the order: zipper The oil yield is controlled, and the test is carried out before production; 2. The cotton garment with metal zipper changes color after dyeing. Discoloration is caused by the chemical reaction of the mouthpiece, the split piece, the slider and the top stop after acid/alkaline dyeing. At present, our company can only add film to the metal parts such as the slider and the microphone (this is paid), but we cannot fully guarantee that the zipper will not react chemically. Please make a sample for testing first to confirm that the zipper is suitable for the garment production process before purchasing large quantities. 3. White-plated nickel-free, rack-plated white-free nickel-free sliders are easy to change color (such as yellowing, black, etc.) on white cotton materials (such as wool products), the main reason is that the bleaching process is not cleaned after dyeing. , caused by reaction with chemical residues. Please wash the fabric to a neutral state before production. 4. 8#, 10# resin, metal puller or larger-volume puller, round puller are not effective for needle detection. On the one hand, it is due to its large size, and on the other hand, the circular pull will generate a magnetic field when testing the needle, thereby affecting the effect of the needle test. 5. The microphone teeth of the discolored metal zipper turn black and the discolored microphone teeth will pollute the clothing. Once the copper alloy is oxidized, it will turn black... Do not seal the packaging bag, keep it breathable, and be careful not to be full of moisture (use moisture-proof Paper, anti-moisture agent, the effect will be better) This article comes from: City Machinery Co., Ltd., please indicate:
