SU1203153A1 - Method of sizing warp yarn - Google Patents

Description

I

The invention relates to a preparatory department of weaving textile industry., In particular, to the method of sizing the warp threads.

The purpose of the invention is to improve the quality of processing by increasing the smoothness of the threads.

Fig. 1 schematically shows an apparatus for carrying out the method; Fig. 2 shows the directionality of the fibers on the polished yarns.

The main yarns 1 (Fig. 1), winding off the incoming packages (warp shafts, reels) (not shown), bend around the roller 2, immersed in a sizing adhesive solution -3 and impregnated. Then, the protruding ends of the fibers are oriented along the filaments in the direction opposite to their two surfaces in zone 4. After orientation, they are carried out. . squeezing v. 5, and after squeezing, they fix the position of the ends of the fibers in zone 6, the orientation of the ends of the fibers in zone 4 and fix their position in zone 6 are performed in different ways: mechanical, electrical, pneumatic, etc. As a mechanical means, 6fjiTb rollers with a nap surface can be used. In this case, linear

The speed of the pile rollers exceeds the speed of the warp threads on the sizing machine. Due to the difference in speeds, nap

5, the surface captures the protruding ends of the fibers, changes the direction of their orientation.

When oriented, the protruding ends of the fibers are inclined in the direction 10 of the Institute, opposite to the movement of the thread, and are adjacent to its trunk. Figure 2 shows the movement of the filaments with a fixed position of the protruding fibers on the weaving machine during the removal of the weaving from the weave. Zone 6

partly extends to the object where the threads did not have time to dry and are in a wet state. This eliminates the tearing of the protruding condes of fibers on the loom, frees up the operation of winding from warp shafts on the weaving mill, and, well preserves the w: ottoman on the surface of the rod ,. helps to reduce

25 breakage due to reduced friction when passing through various elements of the weaving center.

In addition, by reducing the process chain,

30 times to form a weaving mop and production area for equipment to implement the method.
