Process of spinning machine

Spinning machine between the original guide wire machine and a drawing machine tow under low tension after immersion oil groove, groove in the oil agent is heated to 40 to 50 DEG C to tow evenly to obtain continuous drafting oil agent, to ensure the smoothness of the tow, cohesion, and tow temperature is maintained constant. Then three pieces of wire into a drawing machine, drafting roller machine plays a role of guiding the process of drawing and fixed position of the tow. After leaving a drafting machine tow into trough of Water Margin, and immediately into the back of the wet drafting state tow in the stretch zone, namely the second drawing machine and intense heat stereotypes machine, in tension and high temperature (more than 220 degrees) to deal with stereotypes, obtain macromolecular structure complete orientation, the second draft completed draft ratio of about 15% ~ 20%. This process can make the fiber have the characteristics of high strength and low elongation, low shrinkage and high modulus. Tension heat setting machine consists of 18 large cylinders, followed by three drafting machine. The tension heat setting machine is divided into three separate zones. This Xiang in these four and heat setting area can be appropriate regulation of contraction and relaxation level. If the production of wool type low modulus products. You don't need to heat strain stereotypes, can make the tow through these, without heating the cylinder. Cooling work completed by tow cooler, spray to tow oiling agent for steam and the most heat away from the fiber. Then tow in uniform tension into cutting machine was cut into length requirements. After cutting off the fiber is fed into the packaging machine, playing into finished buns. Postprocessing production line by continuously adjustable, independent of the motor to maintain the operation.

Different from the silk tube in tow is a synthesis, and the introduction of postprocessing production line in a certain tension.

A draft piece required raw silk tube number depending on the postprocessing required drawing total size and speed of operation. The draft will be divided into three pieces of raw silk piece into the postprocessing. After leaving the third drawing machine tow into the stack frame, here three slices of tow were folded into a piece, into crimping machine by a coiled heating box. We can adjust the tow crimp crimping machine to achieve pressure. Crimped tow get oil for the last time, and sent to the wire a dryer (relaxation heat setting) evenly, can be dried. This unit is divided into four zones, and heated by steam heated air circulation system. In the former two district in tow drying. In the two district in tow setting processing and free shrinkage. Between a drafting machine and two drawing machine in the first draft zone, tow main draft, by 50 to 80 DEG C hot water bath complete total drafting ratio is 80% ~ 85%. To obtain pre orientation, water bath heating by tow. After leaving the two drawing machine, tension setting unit into tow.
