With the gradual recovery of the global economy and the accumulative effects of the country’s support policies for the textile and garment industry, China’s textile and apparel exports are at a critical stage of stabilization and recovery. However, the textile and apparel industry is also constantly encountering restrictions on international trade protectionism, especially Various kinds of technological trade measures in developed countries are emerging one after another, and their impact on China’s textile exports is increasing day by day. According to statistics, the number of textiles exported to Europe and the United States in 2009 was significantly increased compared with the past. Since 2010, there have been no signs of decline in the recall of textiles exported from Europe, the United States, and other countries. Since Europe and the United States and other countries are major importers of China's textile exports, if they cannot take effective countermeasures against this, they will inevitably have an impact on China’s textile exports.
From the analysis of reported cases in recent years, the main problems in the product are: First, there are defects in product design. For example, the design of string and small parts on children's clothing does not meet the standard requirements; second, the physical and chemical performance indicators related to health and safety are not Reached the importing country's laws and standards requirements, such as formaldehyde, banned AZO, extractable heavy metal content, etc. exceed the standard, the color fastness but off, the fabric's flame retardant properties do not meet the requirements; Third, product packaging, warning signs, etc. do not meet the safety Requirements, such as the use of desiccants containing dimethyl fumarate in the packaging, children's clothing labels or packaging materials did not require the use of warning signs such as age and hazard notices in the instructions for use; Fourth, some products violate the requirements of REACH regulations .
For the reasons, the author believes that the company's awareness of quality and safety and social responsibility is not strong, many manufacturers are keen on pursuing fabric color, functional effects, less consideration of environmental protection, safety factors; In addition, the production enterprises to strict quality of raw materials , The raw materials for the procurement of raw materials and accessories have not been effectively tested; due to lack of understanding of foreign technical requirements or insufficient attention, blindly design, blind production in the production process, the lack of strict control of product quality process.
To this end, the author reminds textile and garment export enterprises to strengthen the management of product quality and safety, strengthen the "awareness of traceability" in production and quality management, and control product quality from the source. In the textile industry, since raw materials and finished products are likely to produce toxic and harmful substances, affecting consumers' health and the environment, we must strictly implement the “source control†measures for the daily use of raw materials, in order to accurately grasp the international market. The latest technology, quality, safety, environmental protection, packaging and labeling and other standards and regulations require full control of raw materials, semi-finished products, finished products, as well as technical, management and production processes to eliminate quality safety hazards and avoid rework and returns. Losses fundamentally guarantee product quality and safety.
SIC
Emery, also known as Silicon Carbide (SiC), is produced by high-temperature smelting of resistance furnaces using quartz sand, petroleum coke (or coal coke), and sawdust (need to add salt when green silicon carbide is produced). Silicon carbide also has a rare mineral, Moissanite, in nature. Silicon carbide is also called Carbon silica. Among the non-oxide high-tech refractory raw materials such as C, N, B, etc., silicon carbide is the most widely used and the most economical one, and it can be called gold grit or refractory sand. At present, China's industrial production of silicon carbide is divided into two types of Black Silicon Carbide and green silicon carbide, are hexagonal crystals, the specific gravity of 3.20 ~ 3.25, the microhardness of 2840 ~ 3320kg/mm2.
Silicon carbide has two common basic varieties of black silicon carbide and green silicon carbide, both of which are α-SiC. 1 Black silicon carbide contains about 95% of SiC. Its toughness is higher than that of green silicon carbide. It is mostly used for processing low tensile strength materials such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. 2 Green silicon carbide contains more than 97% SiC, self-sharpening, mostly used for processing hard alloys, titanium alloys and optical glass, also used for honing cylinder liners and grinding high-speed steel cutters. In addition, there is cubic silicon carbide, which is a yellow-green crystal made by a special process, used for the production of abrasives for bearing superfinishing, surface roughness can be processed from Ra32 ~ 0.16 microns to Ra0.04 ~ 0.02 micron.
