Special composite fiber spinning and winding device by differential-shrinkage differential one-step method

Abstract

The invention relates to a special composite fiber spinning and winding device by a differential-shrinkage differential one-step method, which comprises the following specific processes: preparing raw materials; drying the raw materials, heating and drying the raw material by a heater and wind power so as to remove the moisture; performing screw extrusion; processing the raw materials passing through a separating box (1) by a lower heat conducting roller (3) and an upper heat conducing roller (4) to obtain F threads (5); processing the raw materials passing through a separating box (2) by a thread guide (6), an upper thread guiding roller (7) and a lower thread guiding roller (8) to obtain P threads (9); and putting the threads into a doubling machine (10) and processing the same by an interlacer (11) to obtain composite threads (12), and finally obtaining differential-shrinkage threads (14) after winding (13). The special composite fiber spinning and winding device adopts a one-step method to process composite fibers which are formed through one step, saves a great deal of investment, reduces the production occupied space, reduces the processing cost and improves the production benefit.

Description

Technical field: [0001] The invention relates to a special composite fiber spinning and winding device with differential shrinkage and differential one-step method. Background technique: [0002] Differential shrinkage differential one-step special composite fiber is the main product that has gradually replaced the conventional spinning process for textile raising and fleece fabrics in recent years. It is a project encouraged by the national "Eleventh Five-Year Plan" development. The fabric has a super strong drape feeling and the effects of napping, napping and imitation silk. At present, the production of different shrinkage composite fibers at home and abroad adopts two-step spinning and synthesis processing technology. First process F filaments and P filaments respectively on independent spinning machines, then unwind F filaments and P filaments on another composite machine, and synthesize different shrinkage silk cakes, and there are the following problems in the imita...
