Abstract

PURPOSE:To provide the subject high-quality blended yarn obtained by blending a wool fiber and a silk fiber respectively subjected to resist printing treatment and capable of dyeing with a high chroma and a high solid dyeing effect without causing uneven dyeing between the wool fiber and the silk fiber while preventing the nep part color of the silk fiber from being lightened. CONSTITUTION:For resist printing treatment of a wool fiber such as a wool sliver, the wool sliver is treated with an aqueous solution containing tannic acid, aluminum sulfate, formic acid and a penetrant as a resist printing treatment solution in a continuous sliver-dyeing machine so that the pick up may be 100% based on the wool sliver. The resultant wool sliver containing the abovementioned resist printing treatment solution adhering thereto is then steamed at 100 deg.C for 45min by using a steamer so as to fix the resist printing treatment solution to the wool sliver. The steam-treated wool sliver is then washed and dried to obtain a resist printing-treated wool fiber and a silk fiber such as a silk sliver is blended therewith in a ratio of 70:30, thus obtaining the objective blended yarn capable of dyeing without causing uneven dyeing while preventing the nep part color of the silk fiber from being lightened and of providing a high-chroma product excellent in solid dyeing effect.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wool / silk blended yarn obtained by blending wool fibers and silk fibers, and in particular, when dyed, the silk fibers and the wool fibers have the same color. The present invention relates to a wool / silk blended yarn which has been dyed vividly.

[0002]

2. Description of the Related Art Conventionally, it has been known to produce wool / silk blended yarn by blending wool fibers and silk fibers.

However, when the wool / silk blended yarn in which the wool fiber and the silk fiber are mixed is dyed, the wool fiber is generally colored darker than the silk fiber, and the dyed product has uneven color. However, in particular, there is a problem in that the color of the nep portion, which is an aggregate of silk fibers, becomes light and the color unevenness is conspicuous, and a high-quality product excellent in color uniformity cannot be obtained.

Here, as a method for reducing the occurrence of color unevenness when the wool / silk mixed yarn is dyed as described above, a raw material containing few slabs and neps is used as the silk fiber, and the obtained wool / silk yarn is used. Methods such as gas burning the silk blended yarn and lowering the temperature for dyeing the wool / silk blended yarn can be considered.

However, it is very troublesome and costly to use the obtained wool / silk blended yarn as a gas while using the silk fiber having a small amount of slab or nep as a raw material as described above. Also, even in such a case, there is a problem that the color unevenness between the wool fiber and the silk fiber is not sufficiently improved, and a high-quality product excellent in color uniformity cannot be obtained.

When the above wool / silk mixed yarn is dyed at a low temperature of about 75 ° C., the color unevenness between the wool fiber and the silk fiber is reduced, but the color of the nep portion of the silk fiber is still small. Since it becomes lighter and partially uneven in color and dyes at a low temperature, the color development in wool fibers deteriorates, the excellent color development of silk fibers is suppressed, and the saturation becomes low, which is excellent. There was a problem that products with different colors could not be obtained.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems in a wool / silk blended yarn obtained by blending wool fibers and silk fibers.

That is, in the present invention, when the above wool / silk mixed yarn is dyed, color unevenness occurs between the wool and silk, or the color of the nep portion of the silk fiber becomes light. Not to mention, it is an object of the present invention to obtain a high-quality product having high saturation and being capable of performing dyeing excellent in the same color property and sufficiently performing color development.

[0009]

According to the present invention, in order to solve the above-mentioned problems, as a wool / silk blended yarn, a blended yarn of dye-resisting wool fiber and silk fiber is used. It was developed.

Here, when the wool fiber is subjected to the dye-proofing treatment, various dye-proofing agents conventionally used for dye-proofing the wool fiber can be used. For example, tannic acid, Wool sliver is treated with phenol derivatives such as sulfur condensates of phenolic acid, benzoic acid, dichlorotriazinylaniline, dichlorotriazinylbutylaniline, dichlorotriazinylnaphthylamine, dichlorotriazinylaminosalicylic acid soda Those having bulky hydrophobic groups having amino group blocking effect in wool, such as dichlorotriacin derivatives, were made into aqueous dispersions, and the wool sliver was treated with this, or the wool sliver was treated with sulfamic acid. After that, this is subjected to dyeing prevention treatment by, for example, curing.

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. Adjusted to Polar Br as a dye
ill Red B 125% (CI Acid R
ed 133) at 2.4% owf and dyed at 26 ° C. for 60 minutes, the exhaustion rate of the wool fiber subjected to the dye-resisting treatment is less than that of the wool fiber not subjected to the dye-resisting treatment. 90% or less, preferably 6
0 to 80%. When the exhaustion rate of the wool fiber that has been subjected to the stain-proofing treatment is 40% or less of the exhaustion rate of the wool fiber that has not been subjected to the stain-proofing treatment,
A large amount of the dye-proofing agent is required, which is not practical.

[0012]

In the wool / silk blended yarn according to the present invention, since the wool fiber treated with the dye-proof treatment as described above and the silk fiber are blend-spun, the dyeability of the wool fiber is improved by the dye-proof treatment. It is suppressed so that the wool fibers exhibit dyeability similar to silk fibers under normal dyeing conditions.

Therefore, when this wool / silk blended yarn is dyed under normal dyeing conditions, the silk fiber and the wool fiber are dyed in the same manner, so that a product without color unevenness can be obtained. become.

Further, in the wool / silk blended yarn according to the present invention, since the silk fiber and the wool fiber are dyed in the same manner under the usual dyeing conditions as described above, dyeing is carried out at a low temperature. As in the case, the color of the nep part of the silk fiber does not become light, the color of the wool fiber does not deteriorate, and the excellent color development of silk is not suppressed, and a high-quality product with sufficient saturation is obtained. Will be available.

Penetrant (BASF, Leophen RA) 2g
100% of the wool sliver was picked up by the continuous dyeing machine for sliver using the dye-addition treatment liquid added.

Then, the wool sliver to which the treatment liquid for the dye-proof treatment is applied in this way is heated at 60 ° C. for 30 minutes with a steamer.
After treating for minutes, it was dried.

Then, the wool sliver and the silk sliver to which the treatment liquid for the dye-proofing treatment was applied were mixed and spun into 70th yarn at a ratio of 70:30 in the same manner as in Example 1 above. This is tailored into a drip and 1
It was treated at 40 ° C. for 3 minutes to produce a wool / silk blended yarn.

After the curing as described above, the exhaustion rate of the wool sliver treated as described above was measured to find that it was 68% of the exhaustion rate of the unstained wool sliver. It was about.

(Comparative Example) In this comparative example, the wool sliver was used as it was without being subjected to a dye-proof treatment, and this wool sliver and silk sliver were used at 70:30.
Was mixed and mixed to produce a wool / silk mixed yarn made of No. 60 twin yarn.

Next, the wool / silk blended yarns produced in Examples 1 to 3 and Comparative Example were dyed, and the dyed state was examined.
