In the late 19th century, began to study abroad renewable protein fiber. Italian scientists in 1936, in 1938 the United States, respectively, of ICI companies from milk, peanut, corn, soybean protein extracted from spinning. 1945, the United States, Britain developed a milk protein fiber, but because of poor performance fiber, textile processing can not be interrupted study. In the 1970s, Japan has been successful in developing a different natural fibers and a new type of chemical fiber fiber - containing milk protein synthetic amino acid molecules, that is, today's milk fibers.

After many years of painstaking study, the milk protein fiber research, development and industrialization of scale production was Completed by Shanghai zhengjia milkfiber sci & tech Co., Ltd, which created a new fields in China's textile fibers.

Shanghai zhengjia milkfiber sci & tech Co., Ltd? Is the largest producer of milk fiber in China, the country's leading enterprises, its production process is better than Japan Toyobo technology. "Family" companies not to milk protein fiber research and development and application of the performance, and market development team will be LED by promoting milk fiber market so that the "family" of milk fiber real leadership from this new era of fiber revolution.

Zhengjia milk protein fiber, as the 3-Generation fiber in the wake of natural fiber (1-G fiber) and synthetic fiber (2-G fiber), features the combination of advantages of the both predecessors and boasts more reliable health care and natural bacteriostatic functions.

Zhengjia milk protein fiber, as verified by Shanghai Entry-Exit Inspection and Quarantine Bureau, conforms to the relative stipulations in EEC-released ECO-100 (Textile Eco-Chemical Standards), namely, "Textile exports shall be neutral or slightly acid" and "No cancer-causing or azo dyes is allowed", with the milk silk content accounting for 100% and the pH value being 6.80, indicating the applicability to human skin.

The future starts with the current moment. As a new fiber manufacturer in the 21st century, Zhengjia shall be the market leader devoted to the combination of high technology and nature and a provider for our customers of competitive advantages and development. Up to now, Zhengjia is still a young participator in the fiber industry and in future, Zhengjia shall unite with the vogue analysts, clothing material designers and our partners in the lower supply chain, such as spinning mills, weaving mills and dyeing & finishing factories for the development of new products and catering to the market demands. And our R&D engineers shall be developing new technologies to innovate the production process and cut down product costs, so as to propel Zhengjia's development, expand the scope of application of milk protein fiber and help more people sample the future lifestyle and the feeling of wearing milk. Only in this way can we provide our users with more value-added products.
