The Precautions for Using Zipper of Zipper Machine Summarized by Zhenyu Zipper Machinery
1.Hit color zipper (The fabric is inconsistent with the zipper tape, such as white fabric with black and red zipper tape)must be paid attention to when purchasing and the color fastness must be good. The zippers must be tested and confirmed before sewing before they can be put into production.
2.Zhenyu Zipper Machinery summarizes Nylon zipper is used for PVC fabric or waterproof / skiing fabric (light color). Please note that the fabric will absorb oil stains in the zipper and cause stains on the fabric.
3.Cotton zippered garment with metal zipper will change color after dyeing. Discoloration can occur due to chemical reactions between the teeth, dividers, sliders, and top stops after acid / alkaline staining.
4.White-plated nickel-free and hanging white-plated nickel-free sliders are used for white fabrics (such as woolen products) that are easy to change color (such as yellow, black, etc.),the main reason is that it is not cleaned during the bleaching and dyeing post-treatment, and reacts with chemical residues.
5.It is not effective in detecting needles for 8 #, 10 # plastic, metal sliders or larger volume sliders, round sliders.On the one hand, because of its large volume, the round pull-tab will generate a magnetic field when testing the needle, which affects the effect of the needle test.
The teeth of the metal zipper become black and the discolored teeth will contaminate the clothing. Once the copper alloy is oxidized, it will become black ... Do not seal the packaging bag to maintain its air permeability. Be careful not to fill it with moisture (using moisture-proof paper, Anti-moisture agent, the effect will be better).
The dye on the zipper and the plasticizer, bonding agent, oil agent and other components in the polyethylene, synthetic leather, and resin coating of the cloth may react, and the migration phenomenon occurs. The finished products should be separated by paper, and pay attention to the save status.
Due to the use of tea-colored zippers or black-colored zippers, contamination may occur at the touching area of the clothing and the zippers. In the dyeing process of clothing, chemical reactions occur between the remaining acidic substances or oxidants, and the touching area between the zipper and the clothing may cause contamination. Therefore,the best suggestion is to use fabrics and materials after washed fully.
1)After the washing process, discoloration of zipper mics or corrosion of washing chemicals will weaken the slider. When washing and processing, please use spring head zipper with strong resistance to washing and processing. In order to prevent residual acid during washing process, please wash it to a neutral state. With different types of processing or medicines, the clothing will appear the phenomenon of weakening . And teh experiments must be performed before washing and processing.
2)After the washing process, the self-locking slider was damaged. The zipper is washed while it is open, and debris may enter the slider that makes it easy to break. Therefore, please perform the washing with the zipper closed.
