摘要

IT has also become common to give the present weight of the silk as the basis for percent add on as 10, 30 or 50% after degumming weight. Weighting can also improve certain properties of the silk thread such as 1) Fullness and better handle; 2) More brilliant luster (like for ties); 3) Better flame retardant properties; 4) Better wash and wear properties (crease resistance and less fibre damages). Depending on the processes and amount of weighting serious disadvantages may-result such as 1) Lower dye affinity in poorer dye absorption capacity; 2) Brittleness of threads and tendency to split ends; 3) Substantially lower tensile strength (Becomes lower with storage.); 4) Impaired dischargeability (eg formation of a tin sulphide with sodium hydrosulphate giving a yellow tint to white discharges. Silk was normally weighted in olden days. As time passed on, heavier and delicate fabrics like crepe woven fabrics and materials with good draping qualities were desired, weighting became less important except in fabrics like ties. Still you may consider weighting as an ancillary process for a different fabric for fashion. Polymer grafting treatment has recently become popular it is quite possible that the properties obtained eg wash and wear etc will establish this treatment for special requirements.
