초록
Texturing is the process of including a characteristic of a natural fiber in a synthetic fiber. The most common method of it is the false twist texturing. Nylon textured yarn is primarily manufactured by the disk type. The major process parameters of the disk type false twist machine are speed, draw ratio, disk/yarn, and heater temperature. This study therefore investigated the effects of false twist texturing, especially speed and draw ratio, on the physical properties of nylon textured yarn. The increase of speed was proportional to the increase of unwinding tension, which could reduce the production efficiency by elevating the tension affecting to fiber during the process. In addition, the increase of speed was inversely proportional to the increase of crimp rigidity of nylon textured yarn. Draw ratio was proportionally increased with the increase of tenacity and the reductions of fineness and elongation, showing the influence of draw ratio to the ultimate physical properties of textured yarn.
