GB / T 15107-2005 Introduction of new standards is to adapt to domestic technology development, market economy and the result of changes in consumer attitudes, to further improve the standardization of the shoes production, quality and market development to promote the role of great significance. Because of its casual shoes, sports features are popular. China's current annual output of over one billion pairs of shoes, accounting for more than 50% of global production Nike Air Hypershox shoes, many of the world famous tourist sports shoes brands have established production bases in China. And people's daily life as well as closely related to the vital interests of the consumer products, the introduction of its new standard by the people's attention. Through accurate understanding of standards, the correct understanding of the content standards and rational view of the impact of changes in standards, in order to give full play to the guiding role of the standard, to further standardize the basic indicators of sneakers products to further improve the overall quality of our shoes products.

new standard with the main difference between the old standard:

1, the new standard for the standard scope of application clearly defined. Scope of the new standard to remove the Current professional sports shoes such as tennis shoes, soccer shoes, skate shoes, athletic shoes and other footwear standards have been gradually introduced, changing the past is no criteria to guide the type of shoe situation.

2, the new standards to help increase surface material at low temperature flex requirements. Standards to comply with the former material to help QB / T 2224 , no rupture and cracks and other defects; of man-made upper materials, modification of upper leather, shoe upper leather foil, etc., required (-10 ± 2) ℃ by 30,000 times under the flex test, no cracking and crack pulp, surface defects such as cleft. This new requirement is actually a basic requirement for the upper material is to ensure the durability of the shoe into the basic indicators, the current number of shoe-making enterprises in the fabric requirements for acceptance testing of the project, the new upper material of the future research and development, use, should also be in line with this basic requirement.

3, the new standards may not appear to increase the wear defects affect the technical requirements. The increase in terms of technical requirements to make some more perfect, in line with hiking shoes style rich and diverse use of materials, technology changes and so on.

4, the new standard to superior product quality and qualified product categories, respectively, test to determine. This change in line with the general requirements for development of product standards, taking into account both the quality status of the majority of SMEs, and it helps promote the company products to enhance product quality, superior limit inferior, and promote overall product quality.

5, the appearance of new standards for quality testing project was carried out deletions and changes; This is mainly reflected in the quality of the shoe look more refined and improved, such as the overall appearance of the requirements is no shortage of help at the bottom with glue, a plastic, no visible defects; the corresponding parts of the same pair of shoes all the provisions of the mutual tolerance is more realistic; increase the requirements for assembly, required parts solid, no sharp edges and sharp cutting edge. These characteristics of the specific requirements in line with hiking shoes and a growing emphasis on comfort and to protect against accidental damage and other requirements.

6, the new standard of physical and mechanical properties of the indicators have been adjusted. In addition to qualified products and excellent products into two types of indicators and to increase the low-temperature flex indicators, mainly on the peel strength, folding, wear resistance of the qualified product down the appropriate indicators, such as folding properties of the original standard requirements test . This adjustment is mainly due to the provisions of the original standards are too harsh, shoes materials used does not meet the current changing of the actual diversity and style characteristics, and the original description of the standard is too general, not easy to determine the specifications of the test results, must be its amendments.

7, adds the new standard in Appendix A The appendix is ​​an informative annex, standardized daily wear sneakers happened with the quality of the criteria for the quality of treatment, may be expressly agreed upon in accordance with manufacturer service regulations, or by selling units of local uniform regulations .

seven aspects of the above revised and improved, making the new shoes to adapt to product quality development standards more practical, more conducive to regulate product quality supervision and sneakers grades improve, overall, the new standard is a normal and timely introduction of plate change, the original standard has been implemented ten years, it is necessary for its appropriate revision and improvement. Must recognize that the standard is the general quality of shoes and basic requirements, enterprises should fully improve the quality of the product grade, the real character of its own brand and high quality, it must be the standard as a basis and reference basis to develop and implement its own characteristics and market requirements for more rigorous and comprehensive product standards. In my opinion, manufacturers, trading companies or departments in the future in the further development sneakers product standards, the following aspects should be explored and improved:

(1) on test projects

good shoes in addition to the standard specified in the folding, wear resistance, and outer midsole outsole bond strength, peel strength to help the bottom, the bottom surface of the wall and help peel strength, low-temperature surface materials to help flex the 6 technical indicators are in line with the provisions, the material should also be color fastness, aging, and the upper circumference of the adhesion strength projects reach a certain target requirements. Fastness which include uppers, linings, friction color fastness of the substrate material (dry rub, wet rub), water fastness, perspiration fastness and other properties affect health into the shoes; aging properties, including light materials resistant to yellowing and help, at the end of the material and heat aging resistance, heat aging, the impact into the shoes of durable performance; circumference of the adhesion strength with the upper section and is targeted at around the end wall, curling shoes, etc. class of important indicators. These projects and into the shoes wear properties are closely related, the final product quality control has increasingly become an important project.

(2) on the shoe in the detection of toxic and hazardous substances

detection of toxic and hazardous substances is a major footwear chemical properties of test content, materials used in the manufacturing process a large number of chemical materials , such as natural leather used in leather tanning process, re-tanning agent, grease, dyes, finishing agents of organic and inorganic chemical materials, textile dyeing and finishing processes are also used in many processing agents, additives, etc., synthetic material itself from petrochemical products in its manufacturing process more types of additives, such as initiator, catalyst, plasticizers, leveling agent, anti-aging agent, anti-yellowing agents a variety of special functions of chemical materials , many of these materials on human health or the environment with harmful substances, after a period of product use, precipitation from the materials on human health and ecological environment have long-term harm, and therefore the relevant technical regulations, standards for footwear toxic and hazardous substances contained in the test set forth requirements.

a variety of reasons, not related to the new standard content in this area, but requirements is imperative. Currently, the mandatory standard GB 18401-2003 industry-standard SN 1309-2003 technical regulations and standards, including some eco textiles, eco-footwear standards, technical requirements such as footwear material bound to the main content of chemical performance testing included standard. Current major test for footwear and chemical properties are: phenolic preservative (PCP.TCP), banned azo dyes (AZO) detection, the detection of free formaldehyde content, PH determination, determination of metal elements (such as the natural leather in the hexavalent chromium, cadmium synthetic leather materials (Cd), lead paint coating (Pb), metal parts in nickel (Ni), etc.), plasticizers / vinyl chloride monomer / volatile organic compounds, and so on.

(3) on the requirements of comfort shoes Health

with the reform and opening up and economic development, low-end shoes will gradually withdraw from the stage of history, light, comfort, leisure, sports dual medium and high-end products more and more consumers. To improve product quality, enhance the overall level of products sneakers, shoes must select high-quality materials, the advanced, scientific and rational design of health comfort. As noted in the materials, the most appropriate footwear micro-climate relative indicators are as follows: 21 ℃ -33 ℃, 60% -73% RH, CO2 content of 0.8%, the general surface of natural leather inside the shoe relative humidity around 65% RH, which more appropriate, when the relative humidity inside the shoe> 90% RH, when it will cause discomfort, synthetic leather shoes 1.5-2 hours after the plane will be able to achieve this humidity, and natural leather shoes to achieve this moisture takes 5 hours or more, and thus choose Natural leather shoes easy to produce and maintain a comfortable and comfort longer. In addition to health comfort

related material moisture, breathability and other health performance indicators, but also fabric and composite material of the buffer, shock-absorbing, softness, elasticity, diffusion, ventilation Nike Air Max LeBron 8 (VIII) sale online, cooling nature, as well as static and other comprehensive performance, the performance of the new shoe materials research and development of the higher standards.

All in all Nike Zoom Lebron 9, the introduction of new sneakers and implementing the standard is revised and improved the old standard, but also a new starting point. As the industry's workers, the need for standards and targets all projects be carefully studied, and continuously improve the standard requirements of the project have not been carefully studied, and continuously improve, in particular, there is a certain size and brand of footwear manufacturers, but also to developed and based on high standards and strive to improve internal quality, increase product added value and core competitiveness. So as to keep pace with the development of the situation, to meet the growing consumer groups and the needs of domestic and international footwear market, so China's shoes industry development and growth.
