Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a light-colored warp identification method and a wax agent application device for light-colored warp identification for clearly identifying light-colored warp threads after warp sizing in yarn-dyed fabrics. .

[Prior art]

Prior to weaving yarn-dyed fabrics, warp yarns are unwound from multiple warping beams in a warp sizing machine, made into a single warp sheet, sized and dried, waxed in an after-waxing section, and divided. In the section, the warp yarns are divided into individual warp yarns using a dividing rod (generally called ridge cutting), and then passed through a sizing reed and wound onto a loom beam.

By the way, when weaving colored patterns using various colored warp yarns in yarn-dyed fabric, some of the constituent warp yarns are light in color,
However, in the beam state after warp sizing, it is difficult to distinguish the colors of individual warp threads, and this can result in warp threads of the wrong color being used during weaving preparation or weaving work. This may cause threading of different colors to occur due to incorrect threading.

Therefore, in order to prevent the threading of different colored threads as mentioned above, and to make it easier to identify the light colored warp threads, it has been considered to temporarily color the light colored warp threads to create a color difference, and the following coloring method is used. There is.

(a) When weaving white fabric using different fiber threads for the warp (generally subjected to piece dyeing processing), during sizing, use two-step sizing, etc. to add identification to the size agent in one sizing tank. Coloring dyes are mixed in to temporarily color the fibers to distinguish between different fibers.

(b) For yarn-dyed fabrics that have been dyed with W yarn, dyeing is performed by selecting a dye that decolorizes the woven fabric in processing steps such as desizing mercerization in the state of imperial edict, and dyeing it in the constituent tank. The color of the warp threads is distinguished from each other.

(C) In the cheese and beam dyeing process for yarn-dyed fabrics, temporary dyeing is performed using a coloring dye for identification to identify the colored warp threads in the constituent tanks.

[Problem to be solved by the invention]

However, when the coloring method (a) described above is applied to yarn-dyed fabrics, the following problems are pointed out.

■ It is not possible to handle warp composition patterns with three or more types of colors that are difficult to distinguish.

■ Few factories have introduced two- or three-stage sizing machines, making them impractical.

■ When temporarily coloring with coloring dye for sizing and identification, there is a risk that the coloring dye for identification may not be completely removed during the normal textile finishing process.

The following problems are pointed out in the above-mentioned (mouth) coloring method.

■ Cheese and beam dyeing methods are generally used for yarn-dyed fabrics, which conflict with labor-saving processes.

(2) It is a type of dyeing, and since sizing is performed after dyeing, it is assumed that the identification coloring dye will be difficult to fall off during the normal finishing process of textiles.

The following problems are pointed out in the coloring method (C) described above.

■ This is also a type of dyeing, and since sizing is performed after dyeing, it is assumed that the identification coloring dye will be difficult to fall off during the normal textile finishing process.

■ A portion of the coloring dye for identification is eluted into the sizing glue tank, decolorizing it, and making it impossible to obtain the desired color density.

■ The falling colored dye for identification contaminates the glue tank, etc., causing problems in the process.

This invention has been made in view of the above points, and is a yarn-dyed fabric in which the light-colored warp yarns, which are difficult to identify, are temporarily colored with an identifying color dye to obtain good weavability. It is an object of the present invention to provide a method for identifying light-colored warp threads and a wax agent coating device for identifying light-colored warp threads.

[Means to solve the problem]

A first invention to achieve the above object is that, during warp sizing of a yarn-dyed fabric, the warp drawn out from a plurality of warp beams is made into one warp sheet, which is pasted and dried, and then Apply wax at the after-waxing section,
A method for identifying light-colored warp threads is characterized in that when the warp threads are divided into original warp threads using a dividing rod at the divide portion, the light-colored warp threads are temporarily colored by applying a wax agent for temporary coloring to the entire surface of the warp open surface. , the second invention is a warp sizing machine for yarn-dyed fabrics that is detachably inserted into the warp gap divided into upper and lower parts by a divider rod supported on the machine frame in the divide part of the warp sizing machine for yarn-dyed fabrics. The present invention is characterized by comprising a wax tank containing a wax agent for temporary coloring in a state in which the wax agent is in use, and a rotating application roller supported semi-immersed in the wax agent for temporary coloring in the wax tank, and on which the warp threads slide. A wax coating device for identifying light colored warp yarns in yarn-dyed fabrics.

[For production]

In this invention, in the warp sizing machine, when sizing light-colored warp yarns is mixed, the warp sheet after drying is waxed in the after-waxing section, and then divided into the original warp yarns one by one at the divide section. At this time, by temporarily coloring the light-colored warp threads in a relatively dark color for identification, it is possible to prevent the drawing-through of warp threads of the wrong color due to difficulty in identifying the light-colored warp threads during weaving preparation or weaving work. and good weavability can be obtained. This temporary coloring is then completely removed during the finishing process of the fabric.

In addition, temporary coloring for identification of light-colored warp threads in which light-colored warp threads are mixed is performed using a light-colored warp identification wax agent applied to the warp gaps when the warp threads are divided into individual warp threads at the divide section of the warp sizing machine. This is done by inserting the threads in a removable manner and does not affect the warp sizing work.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

The warp sizing machine to which this invention is applied is a conventional one with a basic configuration consisting of a warping beam support part A, a sizing part B, a drying part C, an afterwaxing part, a dividing part E1, and a winding part F. is the same as

In the warping beam support section A, a plurality of warping beams 2 are supported on the machine frame 1, and the warp threads S are paid out from each warping beam 2 to form one warp sheet S.

The sizing unit B stores a sizing liquid in a sizing tank 3, and includes a sizing roller set 4a that is semi-immersed in the sizing liquid, and a squeezing roller m4b combined with this, and includes a sizing roller set 4a and a squeeze roller m4b combined with this. Glue against.

The drying section C has a plurality of heating cylinders 5 arranged in two stages, upper and lower, and gluing is carried out while the subsequent warp sheet S is passed through each heating cylinder 5 in turn. Drying takes place.

In the after-waxing section, a molten wax agent is stored in the wax tank 6, and a waxing roller that is semi-immersed in the molten wax agent is incorporated. Waxing is performed on the lower surface of all the warp threads S by sliding them on the threads.

The divide portion E is arranged at an appropriate interval on the machine frame 1, and
A plurality of dividing rods 8 are supported at vertically shifted positions, and each rod 8 divides the warp sheet S immediately after waxing into the warps S of the original warping beam 2.

The winding section F is provided with a sizing liquid 9 and has a divide section E.
Each warp yarn S divided by is returned to the warp sheet S again, passed through the sizing liquid 9, the yarn arrangement is adjusted, and then wound onto the loom beam 10.

In this invention, in the divide portion E, a temporary coloring wax application device G is removably inserted into the gap between the warp threads S divided into upper and lower parts by a divider rod 8 supported by the machine frame l.

The main structure of this temporary coloring wax applicator G is that a temporary coloring wax agent colored with an identification coloring dye is stored in a molten state in a wax tank 11, and is semi-immersed in this temporary coloring wax agent. The wax tank 11 is kept warm using steam or the like to prevent the wax agent from coagulating, and the coating roller 12 is connected to a motor in the moving direction of the warp sheet S. rotated relative to

In the above configuration, the wax agent coating device G for temporary coloring is
When inserted into the lower gap of the warp yarn S'' to be temporarily colored which is divided into upper and lower parts by the dividing rod 8, and the warp yarn S'' is brought into sliding contact with the coating roller 12, the coating roller 12 is placed in a molten state.
The wax agent for temporary coloring that adheres to the circumferential surface is applied to the entire circumferential surface of the warp thread S°, and the warp thread S′ is temporarily colored over its entire length.

Here, the warp threads S' are temporarily colored in the following manner.

The warp threads S' that come into sliding contact with the application roller 12 have a large thread pitch and are brought into sliding contact with the application roller 12.
By high-speed rotation, the circumferential speed is increased compared to the warp movement speed of 3°. Therefore, the wax agent adhering to the circumferential surface of the application roller 12 is sufficiently distributed to the circumferential surface of the warp threads S' while the warp threads S' are in sliding contact with each other.

In addition to rotating the coating roller 12 at high speed, in order to sufficiently spread the wax agent for temporary coloring from the coating roller 12 to the circumferential surface of the warp threads S in sliding contact with the coating roller 12, a shallow spiral is formed on the circumferential surface of the coating roller 12. A strip may be formed. When a spiral strip is formed on the circumferential surface of the application roller 12 in this way, when the warp yarns S' slide into contact with the circumferential surface of the rotating application roller 12, a side-sliding force acts on the warp yarns S', and the warp yarns S'' move on the application roller 12. This creates a slight twist to improve the distribution of the wax agent to the surrounding surface.

The wax agent for temporary coloring used in this invention is the same as that used in the after-waxing part, which does not contain water and has high drying properties. Also,
The coloring dye for identification does not dye the fibers (warps) used and is completely decolored during the textile finishing process, and must be well dispersed in the wax agent.

From the results of practical tests, commercially available silk dyes are suitable as the coloring dye for identification. This dye is suitable for materials mainly made of cotton and polyester, so it has the same effect on textiles that use a mixture of both.

In addition, in order to improve the distinguishability of light-colored warp threads, it is necessary to dye them in a deep color, but since the color must be completely removed (removed) in post-processing, the concentration is based on the results of practical tests. The best results were obtained using 20 grams of commercially available silk dye.

In addition, the commercially available silk dyes mentioned above are dispersed in a wax agent and tend to fade when heated for a long time, but practical test results show that two types, silk yellow and silk blue, show less fading when exposed to high temperatures for a long time. Ta.

〔effect〕

As described above, the present invention provides the following effects.

(1) At the warp sizing stage of yarn-dyed fabrics, in order to make it easier to identify the light-colored warp threads, temporary coloring wax is applied to the entire surface of the light-colored warp threads for temporary coloring. This prevents misalignment of colored threads and improves weaving properties.

(2) Since the temporary coloring wax agent is completely removed during the finishing process of the fabric, the color scheme of the product will not change and the product value will not be reduced.

(3) When weaving a fabric with a pattern composed of colored warp yarns and white warp yarns, if the colored fluff flying off from the colored warp yarns is woven into the hot water, it will be very noticeable and the quality of the product will be impaired.However, if this invention is applied, Since waxing is performed evenly on the warp circumferential surface, the fluffing effect is promoted and a high-quality product can be obtained.

(4) It can be applied to existing sizing machines with simple improvements, and the normal sizing speed can be maintained, so there is little impact on efficiency.
