Description

The present invention relates to a method for producing a cotton thread material, a roving thread, a cotton thread, and a cotton cloth, and improves texture and quality of the cotton cloth.

"Prior Art" Conventionally, in the production of dyed cotton cloth, the dyeing step has generally been applied to cotton yarn or cotton cloth.

"Problems to be solved by the invention" However, in such a conventional technique, since the cotton fiber is dyed in the state of the cotton yarn or the cotton cloth, the whole dyeing method is uniform and does not change. In that case, it became monotonous and mundane, and there was a problem that the texture could change and it was not possible to obtain a product with enhanced artistry.

The present invention has been made in view of such conventional problems, and provides a method for producing a cotton thread material, a roving thread, a cotton thread, and a cotton cloth, which enables to obtain various clothing products and the like. It is an object.

"Means for Solving the Problem" The gist of the present invention for achieving the above object lies in the following items.

1 A method for producing a cotton yarn material, which comprises dyeing a cotton fiber which has been subjected to a cotton-waving process of cotton-opened cotton.

21. A method for producing a cotton thread material, comprising: a cotton mixing step of mixing a plurality of different types of cotton thread materials according to item 21; and a carding step of processing the cotton thread material that has undergone the cotton mixing step into a sliver.

32. A method for producing roving yarn, comprising a roving step of processing the cotton yarn material produced by the method for producing cotton yarn material according to Item 32.

43. A method for producing a cotton yarn, comprising a spinning process for processing the roving produced by the method for producing a roving according to Item 43.

54. A method for producing a cotton cloth, comprising a weaving step of weaving the cotton yarn produced by the method for producing a cotton yarn according to Item 54.

"Function" Raw cotton is generally traded in unwound raw cotton, and this raw cotton is opened by loosening the lumps in a cotton opening machine. The unwound cotton is further cleaned and debris-free in a cotton striking process. The cotton treated in the cotton-blowing process stretches the fibers in the next carding process, and collects the stretched long fibers and arranges them in parallel to produce a sliver, which is a thick string-shaped cotton yarn material.

The cotton fibers are dyed after the padding step or the carding step.

What is dyed after the padding process is a cotton thread material that is a collection of cotton fibers with a low degree of convergence, and they may be dyed as it is in the carding process, but before that, put a mixed cotton process and put each color The cotton thread materials are mixed and then made into a sliver in the carding process.

The sliver becomes roving slightly twisted in the roving process, and the roving is processed into cotton yarn in the spinning process and into cotton cloth in the weaving process.

In a continuous automatic cotton cloth manufacturing method, in order to improve the texture, cotton yarn materials of a plurality of colors are mixed and used as an intermediate raw material to be processed into cotton yarn.

It should be noted that blended cotton for mixing different types of cotton fibers, combing for aligning cotton fibers of uniform length, kneading for equalizing unevenness of sliver, compound yarn for mixing yarns, etc. are appropriately performed in the process of producing cotton yarn or cotton cloth.

Further, if the scouring step is placed before the dyeing, the impurities contained in the cotton fiber are removed and the cotton fiber is easily dyed, and a different texture can be obtained depending on the presence or absence of the scouring step.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, until the cotton cloth is manufactured, a cotton-wiping step 1 for treating the cotton that has been opened, a dyeing step 2 for dyeing the cotton fibers that have been loosened, and a dyed cotton fiber. Blending step 3 in which different colors are mixed so as to be distributed evenly to some extent, and a carding step in which the cotton fibers dyed and blended after the beating are processed into a sliver S in the form of a string as shown in FIG. 4, a drawing step 5 for averaging the uneven thickness of the dyed sliver, and a roving step 6 for processing into roving
And a spinning step 7 for converting the roving thread into a cotton thread and a weaving step 8 for weaving the cotton thread into a cotton cloth.

Although not shown, as is well known, a cotton opening process and a cotton mixing process for mixing different types of cotton fibers are provided before the cotton pressing process as necessary. If cotton fibers are entangled with each other in the dyeing process 2, a padding process is added if necessary. After the carding step 4, a combing step for arranging cotton fibers having a uniform length may be provided, and in the weaving step 8, a spun yarn is appropriately made.

If the product is taken out after the dyeing step 2, the single color cotton thread material becomes a product in the state before becoming a sliver, and after the cotton mixing step 3, the mixed color cotton thread material becomes a product. If the product is taken out after the carding step 4, the cotton yarn material in which the mixed-colored cotton fibers are sliver becomes a product, and if the product is taken out after the roving step 6, the roving becomes a product.

Further, when the cotton thread material or the roving thread passes through the spinning step 7, the product becomes a dyed cotton thread. Moreover, after passing through the weaving process 8, a cotton cloth becomes a product.

The padding step 1 is constituted by a padding machine 10 as shown in FIG.

The cotton-blowing machine 10 includes a bedding 11 arranged after the feeding conveyor 11.
a and pedal roller 11b, followed by supply rollers 12,12
A beater 13 for hitting and opening the cotton sent from the supply rollers 12 and 12, and a grid bar 14 arranged under the beater 13.
And cage rollers 15a, 15b for receiving and feeding the cotton transported over the grid bar 14, delivery rollers 16, 16 after the cage rollers 15a, 15b, and a windmill 17.

The carding step 4 is composed of a carding machine 40 as shown in FIG. 4, for example.

The carding machine 40 is configured by sequentially arranging various constituent members after the feed roller 41a provided at the end of the transfer table 41.

That is, after the roller 41a, the scraping roller 42,
A cylinder 43 having needles planted on the outer circumference, a flat chain 44 and a comb 44b arranged so that a flat 44a having the needles planted around a part of the outer circumference of the cylinder 43, and the needles planted on the outer circumference. It comprises a doffer 45 and a comb 45a provided, a converging nozzle 46 and a drawing roller 47, and a sliver receiver 48.

Next, the operation will be described.

Raw cotton is generally traded as raw cotton in a ginned state, and this raw cotton is opened by loosening the lumps with a cotton opening machine. The unwound cotton is further cleaned in a cotton striking step 1 to remove impurities and clean it.

The operation of the cotton-blowing machine 10 which constitutes the cotton-blowing process 1 is as follows.

The cotton sent by the feeding conveyor 11 is caught by the pedal roller 11b while the thickness of the cotton is adjusted by the bedal 11a.
And sent to Beata 13.

The sent out cotton is beaten by the beater 13 and unraveled, flying over the grid bar 14 arranged like a child under the beater 13 and the front of the cage rollers 15a, 15b pulled by the windmill 17. Is sucked into.

The cage rollers 15a, 15b are like hollow cylinders that are formed by arranging wires, and dust and short fibers fall from the gaps of the grid bar 14 before reaching the cage rollers 15a, 15b and are opened. The clean cotton is cage roller 15a,
It is sandwiched between 15b and formed into a flat surface like a mat and is sent out from the sending rollers 16 and 16.

The sent-out cotton fiber is subjected to a scouring step if necessary to remove impurities such as wax and fat contained in the fluffed cotton fiber so that the cotton fiber can be easily dyed and is dyed in the dyeing step 2. .

A plurality of dyed cotton fibers having different colors are collected in the blending step 3 and mixed so as to be distributed evenly to some extent without any bias. This cotton thread material appears to be a single color when viewed from a distance, but it is a material in which different colors are finely distributed when viewed close up.

The dyeing step 2 may be a step of continuously receiving the mat-shaped cotton fibers fed from the feeding rollers 16 of the beating machine 10 and dyeing them. If the product is taken out at this stage, a mat-like cotton yarn material in which cotton fibers having a low degree of convergence are collected is manufactured.

The sliver S, which is a cotton thread material, is produced by stretching the fibers in the carding process 4 and gathering the stretched long fibers in parallel to form a thick string for the cotton that has undergone the cotton-blowing process 1, the dyeing process 2, and the blending process To be done.

The operation of the carding machine 40 constituting the carding step 4 is as follows.

The cotton on the transfer table 41 is scraped by the roller 41a and the roller 42.
It is sent out to bite into. The scraping roller 42 is provided with steel teeth like saw teeth on the surface.When the scraping roller 42 is rotated, cotton is gradually caught on the tooth tips and scraped off, which is the needle tip of the cylinder 43. Is scraped off by the scraping roller 42.

The cotton on the needle of cylinder 43 is flat chain.
Combing between the needles of the flats 44a of the 44, only the relatively long cotton fibers are caught and carried by the tips of the needles of the cylinder 43 and transferred to the needles of the doffer 45. The cotton fibers hooked on the needles of the flat 44a are scraped off by the comb 44b to be dropped.

The cotton fiber caught on the needle of the doffer 45 is scraped off by the comb 45a and hangs down like a thin film. This thin film-shaped cotton fiber becomes a string-shaped sliver S at the converging nozzle 46 and is drawn out by the draw-out rollers 47, 47, and the sliver receiver 48.
Be sent into. If the sliver is taken out at this stage, it becomes the cotton thread material.

Although the roving step 6 is provided as needed before spinning, the unevenness of the thickness of the sliver S is averaged or the contracted fiber is stretched.

The sliver S becomes a roving thread slightly twisted in the roving step 6, and the roving thread is processed into a cotton thread in a spinning step 7 and a cotton cloth in a weaving step 8.

Since the cotton fibers are dyed as described above, the cotton cloth shows a change in color, and when viewed from a distance, it looks like a single color,
As it is a collection of different fine colors when viewed by side, it has a marbled appearance, and there is a difference depending on the viewing angle or the color tone changes, and the taste is different from that of dyeing cotton thread or cotton cloth, It will be artistic and interesting.

The situation in which the cotton fibers change during the batting process 1 to the spinning process 7 is as shown in Fig. 2. In the section A1 corresponding to the bottling process 1, the cotton fibers have not converged and the raw material This is the process of loosening cotton. At this time, multiple types of raw cotton may be mixed.

In the dyeing step 2 and the cotton blending step 3, there is almost no change in the properties of the cotton fibers, colors are imparted to the cotton fibers, and a plurality of types of cotton fibers having different colors are mixed.

The section A2 corresponds to the carding step 4, in which short fibers are removed and long fibers are aligned in parallel and converged to form a thick string-shaped sliver S. The section A3 corresponds to the drawing step 5, and the unevenness of the thickness of the sliver S is averaged as described above, or the contracted fiber is stretched.

The section A4 corresponds to the roving step 6, and the sliver S is a roving in which a weak twist is added. The section A5 corresponds to the spinning process 7, and the roving yarn is twisted to become the cotton yarn.

It should be noted that blended cotton for mixing different types of cotton fibers, combing for aligning cotton fibers of uniform length, compounding yarn for mixing yarns, etc. are appropriately provided in the process of manufacturing cotton yarn or cotton cloth. The drawing step 5 may be omitted, and thereby the dyeing may be changed.

The dyeing step 2 may be arranged after the carding step 4, in which case the sliver S is dyed. Since the dyeing step 2 is performed in a state where the cotton fiber is not twisted, it is more difficult to mix than the one dyed immediately after the beating step, but from the viewpoint of dyeing the cotton yarn or the cotton cloth,
There is a change in the way the cotton fibers are dyed, resulting in a slightly uneven dyeing condition.

For dyeing, an appropriate technique such as dip dyeing or spraying can be used.

In short, the present invention is to obtain a cotton yarn or cotton cloth which is not monotonous but has a texture by dyeing cotton fibers to form a cotton yarn material before becoming a cotton yarn or cotton cloth, and finally making the cotton yarn or cotton cloth. .

"Effects of the Invention" According to the method for producing a cotton thread material, a roving thread, a cotton thread, and a cotton cloth according to the present invention, the cotton thread and the cotton fiber before becoming the cotton cloth are dyed. It is possible to obtain cotton threads or cotton cloth with a texture like dot painting, and the cotton cloth shows a color condition with a change like marbling, and there is a difference or a change in the color condition depending on the viewing angle. It is possible to provide a variety of products that are different from the ones dyed at the stage and have an artistic and interesting taste.
