Milk Fiber fibers tow / tops spun yarns Introduction Properties Applications Grades Processability Background info Supplier Partner Introduction Foreword All through the years, experts have been devoted to the researches on improved fibers and at present they have succeeded in the development of the globally advanced milk protein fiber, a milestone in the international textile industry. Up to now, this kind of fiber was only produced in Japan. The emergence of milk protein fiber updates the traditional definition of animal protein fiber. Being the optimal combination of nature and hi-tech, it is more accommodated to the needs of people’s modern lifestyle. Milk protein fiber is dewatered and skimmed milk which is manufactured into the protein spinning fluid suitable for wet spinning process by means of new bio- engineering technique. Milk protein fiber has passed Oeko-Tex Standard 100 green certification for the international ecological textiles. Milk protein fiber is healthy for skin, comfortable, with bright colors due to good dye ability, etc. The milk protein fiber can be spun purely or spun with cashmere, silk, spun silk, cotton, wool, ramie and other fibers to weave fabrics with the features of milk protein fiber. It can also be used to create top-grade underwear, shirts, T shirts, loungewear, etc. to satisfy people’s pursuit of comfortable, healthy, superior and fashionable garments. The milk protein fiber is a fresh product as a superior green, healthy and comfortable fiber, which will certainly become popular goods in the market as new favorite of the textile trade. Properties Good moisture, absorption and conduction: The fiber base body does not have regular channels, which makes the milk fiber have as fine moisture absorption as natural fiber and better moisture conduction than synthetic fibers - milk fiber is both comfortable and permeable.
