Select the zipper to consider three color fastness

Author:  Source:   Update:2017-07-06  Counting:177
To the clothing selection zipper, not only concerned about the zipper fabric color and fabric of the degree of difference, which is commonly referred to as the color, but also concerned about the color fastener zipper cloth. For manufacturers, whether the color fastness of the zipper reaches the standard level and whether the color shift between the zipper and the dress will directly affect the final product quality.
Color fastness mainly includes the product washable, abrasion resistance performance, generally refers to the dyeing fabric in the use or processing process, subject to external factors (extrusion, friction, soaping, rain, exposure, etc.) under the role of the degree of fading. As a manufacturer, in the choice of zipper suppliers, should be concerned about the three color fastener zipper: resistance to light fastness, soaping fastness and color dyeing, which can avoid the occurrence of these problems, improve the quality of clothing The
Resistant to light fastness
In general, perspiration is accompanied by the sun. Therefore, the light fastness described here is not a single, it includes the sun and perspiration double fastness. Different degrees of sun will lead to a series of photochemical reactions to promote the structure of the dye itself damage, resulting in discoloration and discoloration. At the same time the presence of sweat will make the pH value of the weak acid or weak, which will significantly reduce the resistance of some disperse dyed light fastness. So this composite effect and the simple resistance to light fastness or perspiration fastness is very different.
But through some preventive measures, can enhance this complex resistance to light fastness, so that the color of the zipper for a long time to keep bright. Therefore, the choice of some zipper products, you should use those who have been anti-UV enhanced or directly selected with high light fastness zipper.
Resistant wash fastness
The washability of the zippers is also an important indicator. The general zipper tape is made with 100% polyester weave, using disperse dyes at high temperature. The scrubbing fastness of the disperse dyestuff refers to the degree to which the fouling of the dyed fabric causes contamination of the monofilament or multifiber fabric under certain washing conditions. In theory, because the disperse dyes are dispersed inside the polyester, and the dispersion of the dye concentration from the fiber surface to the inner layer gradually decreased, which makes the surface gathered more dye molecules.
Therefore, the resistance to soaping fastness depends on two aspects: First, the dye itself and the interaction between the size of the fiber molecules, the force is difficult to dye the soap was out of the fiber surface, the small force is the opposite; Is in the dyeing finishing process, the fiber surface dye molecules residue, if the post-processing more thorough, the surface dye residue will be minimal, soaping is difficult to make the zipper fabric fade.
But because the soaping a lot of standards, such as soaping temperature of 40 ℃, 60 ℃ and higher 95 ℃; detergent a lot of types, generally divided into phosphorus and phosphorus; washing time is long and short. Thus, at different washing standards, the resulting fastener tape fastness is not comparable. And the soaping strength is high, will cause the cloth fastness to decline. Therefore, in addition to tell consumers in the usual clothes washing process, for zipper cloth should not use high temperature water and excessive excessive detergent, the general temperature should not exceed 40 ℃, the best neutral and weak detergent, Time is not more than 30 minutes, etc., the most important thing is in the choice of zipper products, as much as possible to choose some high resistance to washing fast washing products.
Color dyeing problem
Many apparel manufacturers often use a special nature of the material, such as PVC, PE cloth and a variety of functional coating of the fabric, the fabric processing technology is more complex, usually will remain some plasticizers, solvents and other chemical additives. It is because of the presence of these auxiliaries that, when exposed to the fiber cloth for a long period of time, penetrates into the interior of the fiber and makes it easier for the dye molecules to diffuse from the inside of the fiber to the surface. If the fabric is white or light, the fabric is easily stained.
To solve this problem due to the spread of the zipper tape color shift, the best way is to use the zipper when it is used to see if the dye can be used with polyester fiber better combination.
Zipper is an important clothing accessories, all aspects of its indicators directly affect the final quality of finished apparel. Therefore, in the choice of zipper suppliers, we must also understand the various aspects of its products, how the indicators.
