Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a method for producing single yarns and marbled yarns made of cotton fibers or blended cotton fiber materials. More specifically, the present invention involves dyeing a roving made of cotton fiber or a blended cotton fiber material in the form of a shinomaki, and then dyeing the roving with a single yarn or marbled 90%.
This invention relates to a method of manufacturing yarn.

BACKGROUND OF THE INVENTION In general, heathered yarn is obtained by twisting two or more colored single yarns, and refers to double-thread heathered yarn.

Since the thickness of such a double yarn heathered yarn is more than twice that of a single yarn, the range of application of the yarn is limited. Therefore, if you are trying to manufacture double yarn heathered yarn with the same thickness as single yarn, the thickness of each single yarn used for double yarn heathered yarn should be less than A, which is the thickness of general single yarn. It is necessary to do so. Therefore, in order to produce thin threads, it is necessary to use long fiber material as the fiber material. This is because if short fiber materials are used, thread breakage occurs and normal threads cannot be formed. However, the fiber material is a high-quality long fiber material, and therefore the price is high. Therefore, if an attempt was made to manufacture double-grained yarns with the same thickness as ordinary single yarns, the cost would be extremely high and it would be uneconomical.

Therefore, in the past, in order to manufacture yarn in multiple colors using a single yarn with a heathered or marbled tone that has the same thickness as a single yarn,
A manufacturing process as shown in FIG. 2 was used. That is,
After the raw cotton is dyed using a bulk dyeing machine, it undergoes the processes of mixed batting, carding, combing, filament, and roving to form roving, and then multiple rovings of different colors are combined to make heather. It was made into thread or marbled thread.

Problems to be Solved by the Invention However, the above-mentioned conventional methods for manufacturing single yarns and marbled yarns have the following problems.

B. After dyeing, before the heathered threads or marbled threads are formed, the second
As shown in the figure, many steps are required, and in each step, losses occur due to short fibers falling off, etc. These losses naturally include dyes, auxiliaries, oils, etc.
This significantly increases manufacturing costs.

In the process shown in Figure 2, when changing colors,
Cleaning work is required to remove lint adhering to the machines used in each process. This work requires a lot of labor, and during this time the process has to be stopped, resulting in a significant drop in production efficiency.

C. Since the dyeing is carried out on raw cotton, the spinning process has to be increased by 10 times, making it difficult to accommodate small-lot production.

Therefore, the present invention aims to provide a method for manufacturing single yarns and marbled yarns that can solve these problems.

Means for Solving the Problems The present invention provides a method for producing single-fiber and marbled yarn, in which roving made of cotton fiber or mixed cotton fiber material is subjected to porous spinning in a roving process. The bobbin is wound parallel to each other in a cone shape at both ends, and a tapered hole spacer is brought into contact with the cone portion.The carrier, in which multiple spacers are installed side by side, is loaded into a dyeing machine and dyed. After oiling, pressure dehydration, and high frequency drying, the dyed roving is used to produce single yarn or marbled yarn.

The method of the present invention having such a configuration can well meet the demands of the textile industry, which is oriented toward producing small lots of many products.

An example of the manufacturing process according to the method of the present invention is shown in FIG.

In the present invention, a roving is formed from raw cotton through a mixed batting, carding, combing, filament, and roving processes according to the normal spinning process, and the roving is baguso-dyed in its shinumaki shape after the roving process. Dye using a machine. As shown in FIG. 3, the shinomaki for dyeing is made by winding a roving 1 around a perforated bobbin 2 for dyeing. The bobbin 2 can also be used for winding in the roving process, and can also be used for supplying the spinning process in a dyed state. Is this perforated bobbin for dyeing made of reinforced plastic? Preferably it is a bottle.

The roving 1 is wound parallel to the bobbin 2 in a cone shape at both ends. Since the cheese rolls in general cheese dyeing are twilled, there is no risk of the winding layer breaking due to the hydraulic pressure of the processing solution during the dyeing process.
In the present invention, since the roving 1 is wound in parallel in a Shinumaki shape, cracks are likely to occur in the wound yarn layer. Therefore, in the method of the present invention, as a preventive measure, a spacer 3, which is a tapered cap-shaped porous lid plate as shown in FIG.

A plurality of the thus-formed roving yarn wraps are placed in parallel on a carrier, loaded into a d' cage dyeing machine, and dyed. There are no particular limitations on the shoe cage dyeing machine used, but the dyeing processing conditions include a Shinomaki density of 0.35.
~0.55, dye liquor flow rate 15 rmin, kg ~20
43/mtn, J, pump head height 20m
~3OFF! It is preferable that the dye liquor is circulated in an in-to-out and out-to-in manner.

After dyeing, oiling is performed using a suitable oil.

The cotton wax has been removed from the dyed rovings, and since the yarns have been compacted due to processing, an oiling agent is applied to the dyed rovings in order to provide smoothness and facilitate subsequent processes such as spinning. As the oiling agent, an anionic oil containing higher alcohol-based sulfated oil is preferable for rovings made of cotton fibers, and a polyhydric alcohol ester nonionic oil agent and higher fatty acids are preferable for rovings made of mixed cotton fibers. Amino-based cationic oil agents are preferred. In addition, the amount applied is 0.2 to 0.0 in pure content.
Preferably, it is 6% o, w, f.

After oiling, the roving is directly subjected to pressure dewatering. 5-10kg/α using specially designed pressure dehydrator
Preferably, pressure dehydration is performed under a high pressure of 2G. By performing dehydration under such high pressure, the winding density is 0.35 to 0.
．． No. 55 Shino-waki roving can be dehydrated to a moisture content of 70% or less.

After dewatering, the rovings are subjected to high frequency drying. Although the conditions for high frequency drying are not particularly limited, 50°C under vacuum
It is preferable to carry out at a low temperature below.

In the present invention, since the winding density of Shinomaki is as high as 0.35 to 0.55, it takes a long time to dry when hot air drying is performed.
4 to 5 hours), which not only reduces production efficiency but also causes problems such as uneven adhesion and deterioration of the oiling agent. However, in the case of high frequency drying as described above, drying can be done in a short time of less than one hour.
No such disadvantage will occur.

The rovings dyed in this way are subjected to a spinning process by combining two or more rovings of different hues, or by combining two or more dyed rovings and undyed rovings, and then It is spun into single yarn or marbled yarn by this method. Alternatively, multicolor marbled yarn can be obtained by returning two or more such rovings to the filament step and the roving step for spinning.

Effects of the Invention According to the present invention, it is possible to inexpensively and extremely efficiently produce single yarns and marbled yarns made of cotton fibers or blended cotton fiber materials, and to produce a wide variety of products without reducing production efficiency. The method of the present invention can be applied to small-lot production, and the industrial utility value of the method of the present invention is extremely high. In particular, in the conventional colored yarn spinning using raw cotton dyeing as mentioned above, the loss rate was approximately 22.75% (in the case of pure cotton combed yarn), in addition to the loss of dyes and auxiliary agents. In the case of the method of the present invention, the loss in the spinning process can be limited to only 0.7 inch, resulting in a significant improvement in productivity.

Example Hereinafter, the present invention will be explained in more detail with reference to Examples.
