Once dominated by cotton and synthetic materials like polypropylene and nylon, fibers of nonwoven fabrics recently have been expanding and diversifying to other natural-positioned materials, ranging from lyocell (mainly Tencel from Lenzing) and cuprammonium (marketed as 'silk' as it mimics the appearance and skin feel of real silk), to bamboo/wood/fruit-derived ones and real silk (infusing silk-derived nanosized protein fiber into nonwoven fabric, to be accurate).
Their degrees of polymerization (DP) values were measured by the cuprammonium hydroxide solution method and given in Table 1.
