Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for producing a woolen cloth having an uneven pattern formed by the fabric portion and the raised portion by partially dissolving and removing the raised portion of a woolen cloth having raised portions on the surface. The present invention relates to a method for producing a woolen fabric in which the raised part of a yarn-dyed woolen fabric having raisedness is partially dissolved and removed, and the fabric part and the raised part have uneven patterns of the same color or different colors by colored discharge printing.

Conventionally, the method for manufacturing woolen fabrics having this type of uneven pattern is to create a uniform nap on the surface of the woolen fabric, and then
There is a way to cut off the brushed hair using a design cutter,
When using this method, the character of the design cutter is that it is possible to reap accurately in the direction perpendicular to the design cutter's blade, but it is extremely difficult to reap in the parallel direction, and it is difficult to reap in the parallel direction. It is possible to cut in a direction of about 40 degrees. Furthermore, there is a problem in that the degree of freedom in expressing the size of the pattern and the lines is restricted due to the size limitations of the head of the design cutter.

Another method is to apply starch to a woolen fabric in a pattern and then raise it, and only the parts that are not covered with starch are raised, but this method allows you to express fine patterns. It is very difficult to do this, and if you do not harden the size of the glue-resistant area with a large L~, the raising effect will be applied to the glue-resistant area, and a clear uneven pattern will appear on the edge part [- Unfortunately, in the final soaping process, there were drawbacks such as poor de-sizing properties and a considerable amount of time required to completely remove the sizing agent.

The present invention has been made with the aim of obtaining a method for manufacturing a woolen fabric having an uneven pattern free from such defects, and in which a woolen fabric obtained by weaving or knitting is coated with full-stripe,
A brushed and felted prevention process is applied, and an alkaline glue containing a reducing bleach and a hygroscopic swelling agent is printed on the raised surface in an arbitrary pattern using a screen method, steamed with saturated steam, and then washed with water. By chemically dissolving and removing the naps in the agent-printed area, it was possible to obtain a wool fabric having an extremely fine and clear uneven pattern consisting of a nap part and a part from which the nap was removed.

However, the most important point in the present invention is that by printing with the alkaline glue, the base material of the woolen fabric is not affected in any way, and only the naps on the glue-printed area are completely removed. However, the problem is how to prevent yellowing of the base fabric portion where the nap has been removed.

Therefore, as a result of various inspections, it was found that etherified galactomannan is resistant to alkali, and also serves as a base material from the viewpoint of fluidity of the adhesive. In order to prevent yellowing of the base fabric part where the nap has been removed, add hydrosulfide formalin condensate to the white side as a glue. It is effective when used in combination with the above composition, and furthermore, a size agent consisting only of the above composition has poor hygroscopicity, and there is a risk that it will become unstable if the nap of the paste printing area is too difficult to remove. It has been found that good results can be obtained by adding a hygroscopic swelling agent such as glycerin and urea, especially urea.

That is, the alkaline sizing agent used in the present invention preferably includes a sizing agent mainly composed of etherified galactomannan (for example, Indalca PAIO manufactured by Cesarvinina), and a sizing agent mainly composed of a potato starch derivative (for example, Abeberei Printex S6) is blended in a ratio of 9=1 to 5:5, and to this is added an alkaline carbonate such as calcium carbonate, sulfur/lium carbonate, sodium bicarbonate, etc.
3-) A mixture of 2 to 10 g of lithium in 100 g of the glue is used. In Part 1-, the sizing agent further contains hydrosulfite as a reducing bleaching agent, particularly a hydrosulfide-formalin condensate abbreviated as Rongarit, and 2 to 1 Og1 per 100 g of the sizing agent.Glycerin, urea, especially as a hygroscopic swelling agent. 7 to 10 g of urea is added to 100 g of sizing agent.

However, it goes without saying that the present invention is not limited to the above-mentioned range of processing agents, and that they can be selected and changed as desired depending on the purpose of the present invention. - The woolen fabric to which the strength wood invention method is applied is a woven or knitted fabric that has been subjected to known processes for fulling, raising, and preventing felting, and in particular, it is intended to be subjected to felting prevention processing. This is to make the raised hair obtained in the raising process more susceptible to the action of the alkaline sizing agent of the present invention, and to remove the raised hair in the finishing or dyeing process after implementing the method of the present invention. This is a treatment that prevents the remaining nap from turning into Fell I and spoiling the appearance.

A screen of 30 to 60 meshes having an arbitrary pattern is placed on the raised surface of the wool fabric thus obtained using a hand screen method or an auto screen method. Apply and print using a rubber cage, steam in saturated steam at 100°C for 10 to 60 minutes 1-1, then wash with water to remove the naps on the area where the alkaline MA agent is printed, and after drying, dye as desired. A finishing step completes the entire process of the invention.

However, when the method of the present invention is applied to a piece-dyed woolen fabric, there is no problem; however, if this method is directly applied to a pre-dyed woolen fabric, the area printed with the alkaline starch will be absorbed by the glue in the glue. Under the action of reducing bleach, the color may disappear or the tone may change.

Therefore, we further examined the method of dyeing yarn-dyed products by printing with an alkaline glue to remove the nap and at the same time coloring the area, and making the area and the area where the nap was not removed the same color or a different color. , Dye used for coloring and discharge printing of wool fabric (!
It was found that for '1, a so-called non-removal type dye that is resistant to reducing bleaching agents should not be used.

Non-removable dyes are dyes with a concentration limit that does not cause a decrease in the strength of wool or other materials. Even when dyeing with a dye concentration of about 0.5%, the dye that does not cause color change or collapse is used. Acid Blue 59), Rhodamine B (Color Index No. Basic Violet 10, manufactured by Hodogaya Chemical Co., Ltd.), Sumilight Yellow BC (Color Index No. Direct Yellow 2, manufactured by Sumikata Chemical Co., Ltd.)
8) is known as a typical non-removable dye.

In the case of coloring and discharge printing using such non-removable dyes, there is usually a limitation that the wool will not be dyed unless the size agent is made acidic.However, in the present invention, dyes can be selected from acid dyes, basic dyes, direct dyes, etc. A non-removable dye that does not lose its color or change its tone in the presence of an alkali and a reducing bleach is added to an alkaline sizing agent containing about 3 parts by weight of sodium carbonate in 100 parts by weight of the sizing agent, It was found that sufficient dyeing was achieved by applying the colored discharge printing technique.

Immediately, 30 to 60 meshes having an arbitrary pattern using the hunt screen method or the auto screen method G are applied to the raised side surface of the yarn-dyed wool fabric which has been subjected to fulling, raising, and felting straight weight processing by known methods. A screen is placed on the screen, and an alkaline glue containing the same kind and amount of reducing bleach and hygroscopic swelling agent as mentioned above, and a non-removable dye of the desired color in the desired N is applied using a rubber cage with a Shore hardness of 40 to 60 degrees. After printing, steaming in saturated steam at 100"C for 10 to 60 minutes, washing with water to remove the raised part of the alkaline paste printing part, and coloring and discharging the part with a non-removable dye,
The entire process is completed by further performing a finishing process.

Next, examples of the method of the present invention will be shown. The woolen fabric used in each example is a 500 g/m woolen fabric that has been subjected to the following steps of washing, fulling, washing, boiling, raising, drying, shearing, anti-felting treatment, and drying using known methods. . or,
All figures in the middle part of the examples are parts by weight.
