Silicone finishing of hemp cotton blended fabric

摘要

Hemp fiber is obtained from the stem of 'Cannabis sativa' plant. The stems are processed to dissolve the gum pectin and to separate the fibers which are then processed again and spun into yarns and finally woven into fabric. The finest hemp fabric is like linen in both hand and appearance. Physical properties of hemp fibers included its length, strength, durability, elasticity, and ability to withstand high temperature without degradation. Since hemp is lignocellulosic bast fiber, it can be blended with other cellulosic fibers such as cotton, jute, coir, ramie, etc. It has been noticed that the hemp cotton blended fabric very often shows stiffness and possess harsh handle due to the presence of lignin. The surface of the fabric is not smooth because of the small protruding fuzzy micro fibrils. In addition to it, after a short period of wear, pilling appears on the surface of the garment giving it an unpleasing look. The problem may be solved to some extent by the use of various softeners on the fabric. The uses of softeners make the fabric feel smooth and prevent them from static electricity buildup, thus playing a vital role in finishing of textiles. Softener is a chemical that, when applied to textile materials, bring about an alteration in hand resulting in the faberic being more pleasent to touch.
