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...

AI Technical Summary

Problems solved by 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 imitation of the two-step method: 1. Large investment; 2. It occupies a large area of ​​land and requires a large volume of workshop; 3. After two times of processing, the material loss is high; 5. The processing procedure is complicated; 6. The quality of the silk cake and the controllability of the production of fixed weight and fixed length are poor.

At present, the system device for special composite fiber spinning and winding with different shrinkage and differential one-step method is still blank in China
