First, when the dyed fiber 7 is installed on the supply roller 10 and power is supplied, the fiber 7 wound around the supply roller 10 rotates at a constant speed.

It is released as it becomes.

The fibers 7 operate differently depending on the color of various patterns and the color of wrinkles.

If the fibers 7 are bleached in various patterns, the fibers 7 released from the supply roller 10 are introduced into the pattern bleached portion 2,

The introduced fibers 7 are transferred to the drum 31 of the pattern forming table 30 by the guide roller 20.

Then, the drum 31 is rotated by the driving roller 34 rotating in a close contact state so that the fibers 7 are moved to the outside of the drum 31.

Sent.

At this time, the contact cylinder of the contact table 40 installed adjacent to the drum 31 is operated and the fibers being transferred to the outside of the drum 31

The adhesion belt 41 is brought into close contact with (7).

When the fibers 7 are in close contact with the outside of the drum 31 by the adhesion belt 41, the pattern bleaching nozzle installed inside the drum 31

In (33), the powder bleaching agent is sprayed onto the pattern disk (32) formed on the drum (31) so that the fibers (7) become the pattern of the pattern disk (32).

It becomes discolored.

The fibers 7 bleached in a pattern pattern in the pattern decoloring part 2 are formed of the guide roller 50 and the conveyer 60 of the wrinkle decoloring part 3.

It is transferred through the transfer roller 61.

At this time, as shown in FIG. 5, when the transfer rod 60 does not discolor the fibers 7 in a wrinkle pattern, the transfer cylinder 62

While moving the feed roller 61 downward, the fiber 7 is transferred to the fiber ironing unit 4 in a taut state.

The fibers 7 transferred to the fiber ironing unit 4 are flatly ironed by the ironing roller 101 of the ironing table 100, and the guide

It is transferred to the fiber winding control table 150 by a roller 90.

Thereafter, when the fiber 7 is transferred to the fiber winding control table 150, the sensing pulley 151 is moved downward due to the load of the fiber 7 to the sensor.

As a result, the driving motor 161 is operated so that the fiber 7 is wound around the take-up roller 160.

Separately, if the fibers 7 are bleached in a wrinkle pattern, the fibers 7 supplied from the supply roller 10 are in the pattern bleached portion 2

It does not decolorize, and is directly transferred to the wrinkle decolorization part 3 by the drum 31 and the guide roller 20.

When the fibers 7 are transferred to the wrinkle bleaching part 3, as shown in FIG. 5, the fibers 7 are transferred by the guide roller 50

When passing through 60, the transfer cylinder 62 of the transfer table 60 operates while the transfer roller 61 loosens the fiber 7 in a loose state.

The pressing plate 71 and the corrugated panel 81 are transferred to the upper part.

Then, as the pair of pressing plates 71 facing each other by the compression cylinder 72 are in close contact with each other, the elastic force of the fibers 7 is removed.

do.

The fibers 7 from which the elastic force has been removed by the pair of pressing plates 71 reach the corrugated panel 81 and, as shown in FIG.

The pressing cylinder 84 is operated so that the insertion rod 86 of the pressing panel 85 feeds the fiber 7 into the corrugated pattern body 82 of the corrugated panel 81.

Then, the powder bleaching agent is sprayed from the pressing bleaching nozzle 83 with the fibers 7 protruding through the crease pattern body 82, and the fibers 7 are wrinkled.

It will be bleached in sheep.

The fibers 7 bleached in a wrinkle pattern are transferred to the fiber ironing unit 4 by the guide roller 50, and the subsequent process is

It proceeds in the same way.
