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.

Dyeing problems and countermeasures:

The quality of the dyes, auxiliaries stability: the product with a different dye manufacturers, including strength and even the same manufacturers, different batches, color is not consistent, even relatively large differences;

Reason: some dye manufacturers, technology is relatively backward, the production management is relatively weak, resulting in the synthesis of the dye depth of color is not stable, and the factory standard difference. So in the process of goods, can only rely on external dye greatly "color" ("the color" which is similar to the dyeing process). The dye intensity, color close to or reach the factory standard.

Dye product palette, actually from a single structure of dye into "mixed dyes", and the mixed component pull performance, and lack of dyeing good compatibility. Because of this, the same dye, not only different manufacturers products exist in depth, color difference. Is a manufacturer of different batches of products, the depth of color is not entirely consistent. In addition some building materials drying dye enterprises backward technology, management level is not high, the various groups of dyes in finished gravity is too large, in the transport, storage, use, produce stratification phenomenon. Lead to the same dye on the package, and lower intensity, color is different. The domestic production of dyeing auxiliaries, no unified standards, many additives manufacturers of the products, the content of components even with a great group of Chengdu Randomness, so dyeing auxiliaries batch and batch, between the barrel and the barrel, there will be quality differences.

Response: the dye additives quality is unstable, so the dyeing sample amplified samples, must be complex. The complex, is in single color before the production according to customer confirmation of prescription sample, then a complex sample, and make the necessary corrections to prescription of complex samples. On the basis of pre production for lofting production.
