Method for manufacturing composite yarn

Abstract

The invention relates to a composite yarn making method, which is characterized by the following: (1) drafting the short fiber yarn by tridiaroller; setting a long yarn lead-in roller to drive by the driving system of former roller on the spinning machine; (2) entering the long yarn into long yarn lead-in roller and long yarn guide wheel then to enter into the former roller; (3) reaching the goalof drafting; (4) leading the chemical fiber long yarn through former roller with the drafted short yarn compound to enter into the feeder hook together; roiling the compound around the bobbin as cop.The invention solves the problem of quantitative adjustment chemical fiber long yarn and short fiber yarn tension ratio and entire spinning tension compatibility of shirting machine, which improves the spinning quality fundamentally by controlling the yarn cohesion closeness effectively. Otherwise, the method contains wider adjustment range, whose production fitness range is wide.

Description

technical field [0001] The invention relates to a manufacturing method of a composite yarn, which is composed of chemical fiber filaments and short fiber yarns. Background technique [0002] On May 10, 2002, the utility model patent specification with the authorized announcement number CN2377258Y disclosed a Sirofill spinning frame, on which not only the work of roving into spun yarn after drafting can be completed, but also the normal return of spun yarn can be completed. Winding, feeding, tension adjustment and broken yarn display control, and twisted and wound together with the drawn yarn to become a Sirofill two-component yarn. On September 1, 2004, the invention patent specification with the authorized announcement number CN1164813C disclosed a sirofill spinning modulus compensation device, which makes filaments and spun yarns with different moduli different in the mold before spinning and forming The amount is close, so that the wrapping of filament and spun yarn is u...

Problems solved by technology

[0003] The present invention mainly solves the problem that the tension ratio of chemical fiber filaments and spun yarns cannot be quantitatively adjusted, and provides a method that can quantitatively control the entry of chemical fiber filaments and spun yarns into the composite point according to different raw materials, different finenesses, and different elongation rates.
