The zipper is composed of two mutually flexible meshing teeth chain and the repeated pull, pull the connector "pull top part, wherein the flexible teeth chain are composed by conventional cloth and cloth, the biggest problem is the color will appear after staining, then we analyzed the the problem:

Dyeing sample sampling amplification rate of accuracy is low, which is due to multiple factors, including the difference between the fiber sample, product quality difference, dyeing and dye additives, quality instability, incorrect dyeing temperature, volatility, water pH applied dyeing, random and dyeing auxiliaries the time is not enough. So an antidote against the disease to take practical measures, can make the dyeing sample put a sample success rate can be improved effectively.

The problems and measures of fabric:

1, the difference of dyeing properties of textile fibers: both synthetic fibers such as nylon, polyester, viscose fiber such as regeneration, or natural fibers such as linen, cotton, different brands, different specifications and different origin, different batches, the dyeing properties are different. The difference degree of order: natural fiber regeneration "< fiber synthetic fiber, differential dyeing properties of synthetic fiber. These natural fiber, recycled fiber, synthetic fiber, we sometimes call the original raw materials, renewable materials and recycling materials;

2, fabric specification differences in color performance caused by different organizations: different specifications of fabric, with different color, namely: different specifications of the fabric even if using the same formula dyeing, the dyeing results (depth, light) will produce significant differences. Countermeasures: analysis from the above differences, differences in the composition of the dyeing properties of fabric fiber and fabric specification by different color performance, will directly affect the dyeing results, so we should pay attention to two points: A, the use of dye sample and enlarge the kind of fabric must be made by the same manufacturer, the same batch, the same the brand, the same specifications, the same origin of fiber (or woven wire), to prevent because of differences in the dyeing properties of the fibers, resulting in dyeing sample is different from the sample amplifying B, sample and dye; enlarge the sample for the weave specifications must be the same, not by different types of fabric To replace the proofing. Otherwise, even with the same specifications of the sample before setting out the fabric complex also tend to like, because the fabric color effect and reach the customer confirmed sample.

Greatly "color" ("the color" which is similar to the dyeing process). The purpose is to make the light intensity of dye, close to or reach the factory standard.
