Embodiment 1

[0011] figure 1 The rotary cylinder treatment method before dyeing or bleaching of elastic yarn or fiber is realized in this way: first, the yarn or fiber to be dyed or bleached is wound on the large bobbin (3) with a common winder . There are many grooves on the outer surface of the large bobbin (3), when the yarn or fiber is wound on the large bobbin (3) to form a yarn or fiber roll, the yarn or fiber roll (2) and the surface of the large bobbin (3) There will be gaps between the grooves. Then insert the manipulator (1) into the gap between the yarn or fiber roll (2) and the large bobbin (3) (the manipulator is a mechanical device like a claw, and the claw can be opened under the action of power. can be closed), the claws on the manipulator (1) are stretched out under power, and stretch the elastic yarn or fiber roll (2), so that the large bobbin (3) can be pulled from the yarn or fiber roll (2) ), then put the small bobbin (4) covered with holes on the surface into the y...

Embodiment 2

[0013] figure 2 The rotary cylinder treatment method before dyeing or bleaching of elastic yarn or fiber is realized in this way: first, the yarn or fiber to be dyed or bleached is wound on the large bobbin (3) with a common winder . The surface of the large bobbin (3) is smoother and has a certain taper. Then, place the large bobbin (3) wound with yarn or fiber roll against the baffle (5), insert the end with a larger diameter into the round hole on the baffle (5), and press the push rod (6) Arriving at the end of the smaller diameter of the large bobbin, the push rod (6) pushes the large bobbin (3) out of the yarn or fiber roll (2) under the action of power. The push rod (6) is covered with a small bobbin (4) full of holes. When the large bobbin (3) is pushed out, the push rod (6) simultaneously sends the small bobbin (4) into the yarn or fiber roll ( 2) in. At this time, the yarn or fiber roll (2) naturally shrinks to cooperate with the small bobbin (4) full of holes, ...

Abstract

The present invention relates to a drum treatment method of elastic yarn or fibre before which is dyed or bleached. Sid method includes the following steps: using cone winding machine to make elastic yarn or fibre roll to be dyed or bleached be winded on a large bobbin, then using mechanical equipment to take out said large bobbin and replace it with small bobbin covered with eyelet all over so as to make the yarn or fibre roll with elasticity obtain natural constraction to meet required tightness and density for dyeing or bleaching.

Description

technical field [0001] The invention relates to a treatment method of yarn or fiber before dyeing or bleaching, especially a treatment method of elastic yarn or fiber roll before dyeing or bleaching. Background technique [0002] At present, the treatment method of the textile industry before yarn dyeing or bleaching is: the yarn or fiber roll to be dyed or bleached is wound on a bobbin full of holes with a winder, and then placed on the dyeing machine. On the dyeing column of the yarn container, put it into the package dyeing machine for dyeing. When the dyeing machine dyes the bobbin yarn or fiber, the yarn or fiber bobbin is still, and the dye solution is continuously circulated between the yarn or fiber by the delivery of the main pump, so that the dye is dyed. Therefore, the tightness and density of the yarn or fiber winding on the bobbin must be appropriate, so that the dye solution can penetrate into the yarn or fiber roll, and the inside and outside of the yarn or f...
