[Previous technology] According to '1930's η eber 1 ei η's method of "twisting-heat setting ~ unbending" was applied to the processing of slime, and the winding effect similar to wool was spun; since then' The raw silk is endowed with processing methods such as false-twisting, airjet, stuffing, kn ife-edge, etc. The fluffy and stretchable characteristics 'become the technical basis of the human fiber processing industry; at the same time, the improvement of the spinning technology has made the P 0 Y part forward yarn (pre 〇r 丨 ent γ arn) the mainstream of the market' products and the traditional needle spindle type The false twisting mechanism cannot meet the processing requirements due to mechanical factors. On the other hand, the mature development of friction false twisting has improved the false twisting efficiency, and at the same time, the processing speed is up to 12,000 m / min. In the past, the spinning of POY in spinning mills could not be directly used for subsequent fabric processing. The thermal false twist setting effect of a false twisting unit must be used to achieve the effect of fluffy processing. Under the fierce market competition, it was necessary to seek more Competitive process processing.
