BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carded yarn for post-dyeing, which is colored in an appropriate color by post-dyeing,
In particular, the present invention relates to a worsted yarn for post-dyeing, which is capable of obtaining a fabric in which yarns of various colors are mixed by dyeing the fabric with various kinds of dyes.

[0002]

2. Description of the Related Art Conventionally, in the manufacture of a fabric in which various colors are mixed, yarns of various colors which have been dyed in an appropriate color in advance are used in an appropriate combination to combine the desired colors. To obtain a cloth.

Here, in the case where a fabric in which various colors are mixed is manufactured by using the yarns which have been dyed in advance, many kinds of yarns dyed in various colors are manufactured and stocked. Incidentally, it was necessary to use the yarns dyed in an appropriate color in combination from the many types of yarns thus stocked.

However, in manufacturing a fabric in which yarns of various colors are mixed, many types of yarns dyed in various colors are produced and stocked to obtain the desired color of the fabric. It is troublesome to select and use a yarn dyed in an appropriate color from a large number of yarns each time, and productivity is poor and cost is high. There was a problem that management became troublesome.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems in the case of manufacturing a fabric in which threads of various colors are mixed.

That is, according to the present invention, when manufacturing a fabric in which threads of various colors are mixed, many kinds of threads dyed in various colors as described above are manufactured and stocked, Depending on the color of the target fabric, it is not necessary to select and use a yarn dyed in an appropriate color from many types of yarn each time, and a fabric in which yarns of various colors are mixed is used. It is an object to make it easy to manufacture.

[0007]

According to the present invention, in order to solve the above-mentioned problems, as the first worsted yarn for post-dyeing, at least a dye-resisting processed wool fiber and a chlorinated product are used. A post-dyeing cardboard composed of a modified or chlorinated / resin-treated modified wool fiber and a pre-mordanting-treated or chlorinated or chlorinated / resin-modified wool fiber The wool is also used as the second worsted yarn for post-dyeing, at least the wool fiber of the cloth, the modified wool fiber that has been chlorinated or chlorinated / resin-treated, and the premordanting treatment and chlorination or chlorination.・ We have developed a carded yarn for post-dyeing, which is composed of pre-mordanting modified wool fibers that have been subjected to resin processing.

Here, in the first and second post-dyeing worsted yarns according to the present invention, when the chlorination treatment or the chlorination / resin processing treatment is performed on the wool fiber, it is generally performed on the wool sliver. The chlorination treatment or the chlorination / resin processing treatment can be performed by a known method such as the Chloy method or the spirit pad method.

Further, in order to obtain the pre-mordanting modified wool fiber which has been subjected to the pre-mordanting treatment and the chlorination treatment or the chlorination / resin processing treatment, the chlorination treatment or the chlorination / resin processing treatment is carried out as described above. The obtained wool sliver can be obtained by premordanting by a commonly known method.

Further, when using the dye-resisting processed wool fiber which has been dye-resisting processed like the above-mentioned first worsted yarn for dyeing, a dye-resisting agent which is generally used for dye-resisting wool fiber, For example, phenolic derivatives such as tannic acid or a sulfur condensate of phenolic acid, benzoic acid or dichlorotriazinylaniline, dichlorotriazinylbutylaniline, dichlorotriazinylnaphthylamine, dichlorotriazinylaminosalicylic acid soda, etc. A dye having a bulky hydrophobic group having an amino group blocking effect on wool, such as a syn derivative, or a stainproofing agent such as sulfamic acid can be used. When the wool fiber is subjected to the dye-proof treatment as described above, it is possible to use the modified wool fiber chlorinated as described above as the wool fiber to be dye-proof treated.

Further, in the first worsted yarn for post-dyeing, the dye-resisting processed wool fiber as described above is used,
Since it is used in combination with the above modified wool fiber, a stain preventive agent for nylon consisting of a polyvalent anion compound such as an aromatic sulfonic acid condensate, or a wool insect repellent such as a urea derivative is used as a stainproofing agent. You can also

In the case of using sulfamic acid as the stain-proofing agent in performing the dye-proofing treatment as described above, it is necessary to apply the sulfamic acid to the wool fiber and then to cure it. .

When the wool fiber is subjected to the dye-proof treatment as described above, the degree of the dye-proof treatment of the wool fiber is such that the bath ratio is 1:80 and the pH is 2.3 with hydrochloric acid. Adjust to the dye (Polar Brill
1 Red B 125%) was allowed to act for 2.4% owf and dyed for 60 minutes at 26 ° C., the exhaustion rate in the dye-resisting printed wool fiber was 19% or less
It is preferably 5 to 15%. It should be noted that in the case of fibers that have not been subjected to a dye-proof treatment, the above exhaustion rate is
% Or more.

In the first and second post-dyeing worsted yarns of the present invention, in addition to the above-mentioned various wool fibers, colored wool fibers which are wholly colored are used together. Good.

[0015]

In the first carded yarn for post-dyeing according to the present invention, at least a dye-proof treated wool fiber,
A modified wool fiber that has been chlorinated or chlorinated / resin processed, and a pre-mordan modified wool fiber that has been premordanted and chlorinated or chlorinated / resin processed Further, in the second worsted yarn for post-dyeing, at least the wool fiber of the cloth, the modified wool fiber which has been chlorinated or chlorinated / resin-treated, and the pre-mordanting treatment and chlorinated or chlorinated -Because it is configured by using a pre-mordanting modified wool fiber that has been subjected to resin processing, by dyeing these post-dyeing worsted yarns by combining an appropriate type of dye, each wool described above Each fiber is dyed in a different color with the appropriate type of dye.

That is, in the above-mentioned first and second post-dyeing worsted yarns, the portion of the modified wool fiber that has been chlorinated or chlorinated / resin processed is generally used for dyeing wool. It becomes deeply dyed by various dyes.

Further, in each of the above-mentioned worsted yarns for post-dyeing, the pre-mordanting-modified wool fiber portion which has been subjected to pre-mordanting treatment and chlorination treatment or chlorination / resin processing treatment is an acid mordant such as chrome dye. In addition to the dye, it is dyed with an acid dye or a reactive dye.

On the other hand, the dye-resisting treated wool fiber in the first post-dyeing worsted yarn is generally maintained in a state of being hardly dyed by the post-dyeing. However, when the chlorinated wool fiber subjected to the dye-proof treatment is used as the dye-proof wool fiber, it is colored with a cationic dye.

The second woolen yarn for post-dyeing contains the modified wool fiber that has been chlorinated or chlorinated / resin-treated as described above, so that the wool fiber of the cloth is also used. The dyeing is suppressed, and it is maintained in a state of being hardly dyed, or even if dyed, only a light color is dyed.

Therefore, by producing a cloth using the first and second post-dyeing worsted yarns of the present invention, and then dyeing the cloth with various kinds of dyes, various colors can be obtained. A fabric having a mixture of yarns can be obtained.

[0021]

EXAMPLE A carded yarn for post-dyeing according to an example of the present invention will be specifically described below.

Example 1 In this example, white wool fiber, modified wool fiber treated with chlorination and resin, and premordanting treated with premordanting treatment and chlorination treatment. A modified wool fiber was used.

As the chlorinated / resin-processed modified wool fiber, a wool sliver which has been chlorinated / resin-processed by the known Chloe method is used.

As the pre-mordanting modified wool fiber which has been subjected to the pre-mordanting treatment and the chlorination treatment, potassium dichromate is used for the modified wool sliver which is obtained by chlorinating the wool sliver by the known Chloe method. 2% owf, formic acid 2

Then, after 100% of the dye-resisting treatment liquid was picked up with respect to the wool sliver by a continuous dyeing machine for sliver, the wool sliver to which the dye-resisting treatment liquid was applied in this way was
Steaming was performed at 8 ° C. for 45 minutes to fix the dye-proofing treatment solution to the wool sliver, and then the wool sliver was washed and dried.

Further, in Example 4, as a treatment liquid for the dye-proofing treatment, sulfamic acid was added in an amount of 150 in 1 liter.
g, a penetrating agent (manufactured by BASF, Leophen RA) was added at a rate of 2 g so as to use a treatment liquid for dye-proof processing. Then, 100% of the dye-resisting treatment liquid was picked up with respect to the wool sliver by a continuous dyeing machine for sliver, and the wool sliver to which the dye-resisting treatment liquid was applied in this way was heated with a steamer at 60 ° C. for 30 minutes.
Treated for minutes, after which the wool sliver was allowed to dry.

Further, in Example 5, 200 g of a urea derivative (Mintin FF, manufactured by Ciba-Gaiki Co., Ltd.) and a penetrating agent (BAS) were used in 1 liter as a treatment liquid for a stain-proofing treatment.
A treatment liquid for dye-resisting processing to which 1 g of Leophen RA (manufactured by Company F) was added was used. And 100% of this treatment liquid for dye-proof processing is applied to wool sliver
After being picked up, the wool sliver on which the treatment liquid for dyeing prevention treatment was thus picked up was steamed by a steamer at 100 ° C. for 45 minutes to be fixed, and then this wool sliver was washed and dried.

On the other hand, as the above-mentioned modified wool fiber, a wool sliver treated by chlorination and resin treatment by the known Chloy method is used.

As the pre-mordanting modified wool fiber which has been subjected to the pre-mordanting treatment and the chlorinating treatment, the wool sliver is chlorinated by the known Chloe method in the same manner as in Example 1 above. After applying 2% owf of potassium dichromate and 2% owf of formic acid to the wool sliver, it was boiled for 45 minutes, and further hydrosulfite was added to this wool sliver at 1% owf, and 90% of this was applied.
After the treatment at 20 ° C. for 20 minutes, this wool sliver was washed with water, dried, and pre-mordanted.

Then, each of the dye-proof processed wool slivers obtained as described above, the modified wool sliver described above, and the premordanting modified wool sliver described above are respectively 40:30:
It was mixed-spun at a ratio of 30 to obtain a carded yarn for dyeing of each example.

In addition, in the worsted yarn for dyeing of Example 4 using the dye-coated wool sliver dye-coated with sulfamic acid, after blending as described above, it was made into a crepe and quipped. The machine was subjected to a curing process.

Next, Example 2 manufactured as described above
Each of the fabrics is manufactured using each of the post-dyeing worsted yarns of Nos. 5 to 5, and a brown acid mordant dye (C.I. Mordant Brown 3) is applied to each of the fabrics thus manufactured.
