NOVELTY - The method involves forming a spandex containing far-infrared graphene fiber by the processes of melt-spinning, weaving, presetting, and finishing after dyeing the auxiliaries. The graphene and tourmaline are used as auxiliary agents and polyurethane chips as master batches in melt-spinning process, where tourmaline is Xinjiang tourmaline, and the mass ratio of graphene to tourmaline is 1.5-4. The graphene and tourmaline is groubded, and anhydrous ethanol is used as a solvent, according to a mass fraction of 10-15%, and then n-propylamine is added, ultrasonically assisted to mix uniformly, and spray-drying. The process adopts a cotton yarn size of 26-36 inch cotton combed yarn, wherein the yarn ratio is 90-98% of the cotton yarn, and the functionalized spandex yarn is 1.8-3.0%. USE - Preparation method of far-infrared and deodorant knitted fabric. ADVANTAGE - The far-infrared and deodorant functional knitted fabric made by the method has simple preparation process, a far-infrared emissivity of 78%, and good gas permeability and heat preservation performance, and at the same time gives functions such as far infrared and deodorization, which enhances the appreciation space of knitted fabrics and has a very broad market prospect.
