Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a continuous wet rubbing apparatus for twill cotton fabric, namely jeans.

In recent years, as shown in Figures 1 and 2, outer clothing such as trousers, called jeans, made of marbled 2/1 twill weave cotton fabric consisting of dark blue warp X and white weft Y has become popular. There is.

However, these jeans have a strong dark blue color with many of the warp threads X exposed on the front side, making them look brand new.They are also thick and rough to the touch, so the dark blue color fades after repeated washing. Relatively flexible items that looked whiter and worn out were preferred.

The purpose of this invention is to meet the above-mentioned demands.

That is, in this invention, a plurality of friction engraving rollers, a plurality of guide rollers for presser foot, and a water discharge pipe are arranged alternately, and the engraving roller elastically contacts the cloth via a spring or the like, and also moves in the direction crossing the cloth. A cloth supply unit is slidably mounted at one end of these roller rows,
This is a continuous wet cotton cloth friction processing device in which a cloth take-out section is attached to each end of the cloth, the cotton cloth is moistened and passed through at a required speed, and the surface of the cloth is rubbed to fade the dark blue color.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. As shown in FIG. 3, the continuous wet cotton cloth friction processing apparatus of this invention includes a cloth supply section 1, a dipping-type swelling treatment section 2, a roller-type friction processing section 3, a heating roller-type drying section 4, and a cloth shaking-off section 5. Consists of a combination of.

The immersion type swelling treatment section 2 consists of a water tank 6 and a plurality of upper and lower guide rollers 7, and performs swelling treatment by adding and dissolving chemicals such as hydrosulfite, bleach, detergent, etc. in the water tank 6 in a required ratio. At the same time, decolorization treatment is also performed. A roller-type dehydrator 8 and a fabric tenter 9 are installed between the friction processing section 3 and the friction processing section 3 .

As shown in FIG. 4, the roller-type friction processing section 3 includes a plurality of friction engraving rollers 10 whose outer circumferential surfaces are engraved with required irregularities and a plurality of presser foot guide rollers 11 that alternately form a circular side surface. arc shape and engraving roller 1
The engraving roller 1
A high-pressure water discharge pipe 12 is installed next to 0, and the center of the upper part serves as a cloth entrance and exit, and two pairs of guide rollers 13 are installed here.
is attached.

Each engraving roller 10 is supported by bearings 14 at both ends to be slidable in a radial direction by bearing members 15 arranged in a star shape, and is connected to a variable speed motor 18 via a chain 17 attached to a chain wheel 16 at the end of the shaft. is rotated at the required speed. The bearing 14 is in elastic contact with the cloth A by the shock absorbing device of the helical spring 19 on the outside, and is abutted and locked on the threaded rod 20 on the inside. The engraving roller 10 is elastically swung outward by external forces such as vibrations and sag received from the running cloth A, thereby preventing damage to the cloth and fading spots. Turn the threaded rod 20 to slightly move the engraving roller 10 in the radial direction to create the cloth A according to the type of cloth A.
The contact area can be adjusted as appropriate.

The presser foot guide roller 11 is driven by a variable speed motor 23 via a chain 22 attached to a chain wheel 21 at the end of the shaft to a rotation speed that is the same circumferential speed as the engraving roller 10. Furthermore, an upper roller 24 for elastically clamping the cloth A is attached to each guide roller 11, and a buffer device 25 is attached to the upper roller 24. The cloth A is moistened by the water discharged from the high-pressure water discharge pipe 12 and comes into contact with the engraving roller 10 with a soft touch. This high-pressure water discharge pipe 12 can adjust the water pressure and water discharge amount as appropriate.

A tension roller 26 and a roller dehydrator 8 are installed outside the cloth outlet of the roller type friction processing section 3.

The heated roller type drying section 4 consists of a large number of steam heating drums 27, and the cloth A is dried and ironed while being sent in surface contact with each steam heating drum 27 that rotates at the same circumferential speed as the cloth speed. Ru.

The continuous wet type cotton fabric friction processing apparatus of the present invention can omit the dipping type swelling treatment section 2 and the heating roller type drying section 4, and can also be used as a main part in other continuous type cloth finishing apparatuses. A processing section 3 can be added. In addition, the roller-type friction processing section 3 includes an engraving roller 10, a guide roller 11, and a high-pressure water discharge pipe 12 arranged in the circular arc shape on the side as described above.
They can also be arranged in a straight line.

The continuous wet cotton cloth friction processing device according to this invention is
The structure is as described above, and when this is used, the cloth A is fed to the cloth supply section 1 so that the front side of the cloth A comes into contact with the engraving roller 10. Engraving roller 1
The number of rotations at 0 and the contact area between the engraving roller 10 and the cloth A are adjusted as appropriate by checking the type of cloth A and its finished state.

The cloth A absorbs water and swells in the soaking-type swelling treatment section 2, and is decolorized by chemicals such as hadrosulfite and bleach in the solution, so that the dark blue color of the warp yarns X fades. Next, in the roller-type friction processing section 3, the cloth A is moistened by spraying water and comes into contact with the uneven surface of the engraving roller 10 rotating at high speed, so that the dark blue warp X (see Fig. 1 and (See Figure 2)
The threads are shaved off and the fuzz etc. are removed, making it look worn out, and more of the lower white weft yarn Y becomes exposed, giving it a discolored appearance. In the heated roller type drying section 4, the cloth A is dried and ironed so that the cloth can be immediately shipped as a product.

As mentioned above, the continuous wet cotton cloth friction processing device of this invention can produce a worn-out feeling at high speed and efficiently, for example, for dark blue marbled jeans, it can produce a faded white color. In addition, the degree of friction can be adjusted easily and conveniently.
