一、 HOK zipper is green products, in line with international environmental standards:
　　HOK zipper of the ITS, to meet the EU Oeko-tex srandatd 100 environmental standards, which outline of the five major:
　　1、AZO: Zipper azo dye with less than 30 ppm of the dye.
　　2、heavy metals: copper, Ziding, painting materials, use less than 600 ppm Pb, Cd less than 100 ppm, 60 ppm antimony, arsenic below 25 ppm, 60 ppm chromium, barium less than 1000 ppm, less than 500 ppm selenium, less than 60 ppm of mercury material.
　　3、Nickel: Rafah head, bolt the upper and lower levels only, nickel plating process, and so ensure that the release is less than 0.5 ug/cm2/week.
　　4、carcinogens: staining, painting, electroplating, pigment, and so should not be used carcinogens.
　　5、of allergy caused by: staining, painting, plating, such as pigment-induced anaphylactic of less than 1 mg / L, respectively.
　　6、formaldehyde: formaldehyde resin material contained less than 25 ppm.
二、 zipper metal magnetic materials have to national requirements to meet international standards.
三、 metal zipper special surface treatment, rust-proof, decolorization.
四、 pull the first use of new technologies to improve the dynamic for a 4:00 Rafah head (patented).
E paint Rafah Surface Enhanced Treatment using various high-temperature washing water not paint stripping, Acid and Basic Resistance.
五、use imported yarn, high temperature monofilament line, and other special materials and the stereotypes, zippers started straight, not unilateral rotation enables zipper and matching clothing shrinkage of the same to ensure that the garment-Ting, deformation.
六、 physical performance indicators: 1, anti-Tension 2, shift strength 3, the overall strength 4, the Light of Waterloo 5, color fastness, and so far more than industry standards.
