1. Zipper application objects
When purchasing zippers, it is best for the purchaser to inform the zipper manufacturer what type of product the zipper is used on, whether there are any special post-processing requirements for the product, whether it needs ordinary water washing or acid enzyme washing, etc. This will facilitate the zipper manufacturer to make appropriate adjustments to the quality and personalized requirements of the zipper based on the requirements for supporting products.
2. Zipper length and allowable tolerance
The meaning of zipper length is different for different zipper types. Since the zipper is a flexible fabric, it will have a certain expansion and contraction rate when subjected to external forces. This must be taken into consideration when purchasing a zipper and determining the size.
3. Requirements for zipper components
Since different countries and regions have different environmental and ecological requirements for textiles, the inspection methods are also different. In particular, the grade requirements for azo, heavy metal-free, and needle-proof vary greatly. Therefore, when purchasing zippers, it is best to indicate the country and region where the product is exported, or directly put forward requirements for the zipper ingredients.
4. Safety Tips for Zippers on Children's Clothing
In order to ensure the safety of zippers in children's clothing, we must not only control the chemical composition of zipper products, but also have requirements for metal accessories. For example, we recommend the use of injection-molded top and bottom stops, and metal accessories must have no sharp edges to avoid sharp corners that can injure and scratch children's skin.
Matters needing attention in continuous dyeing of ribbons

1. Factors of ribbon blanks: First of all, we should pay attention to whether the yarn used in the ribbon blanks is from the same batch, because the "oil" contained in different batches of yarn is different. If it is blended, it will become a factor of the color in the dyeing process; secondly, whether the blank has been pre-treated. The dyeing effect of the refined blank is very good, because the "oil" on the yarn is removed after treatment, and the dye can be directly in contact with the fiber for dyeing without protection.
