As a wholly-owned subsidiary of the shenzhen all-tropical age science and technology company, which was affiliated with the shenzhen all-tropical age, the company succeeded in expanding its medical products to civilian products with 25 years of professional and productive experience in the health-care cotton industry, with its original “choose-free patent process”. The company's production of the purcotton all-tropical line of raw materials, such as pure cotton towels, princess ness series of sanitary towels and ness baby cotton diapers, fills the gap in the use of full-tamp material for many items. This young brand was born in 2009 in the all cotton age of purcotton, a combination of words taken from pure+cotton to produce healthy, skin-based, high-quality life-care items from natural cotton. Purcotton is an entirely new product produced as an autonomous intellectual property patented technology whose production processes have been patented in more than 50 countries and territories worldwide. The good quality of the products produced by the process has been widely recognized by the international medical community and by the textile industry, which will gradually replace the whole cotton products produced through traditional processes as a new generation of natural cotton-free rags called "a great revolution in the textile industry"。
