Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for producing wool fiber products having a multicolor effect such as a heathered tone or marbled tone by one-bath dyeing with an anionic dye.

Conventional technology Traditionally, when manufacturing wool fiber yarns and knitted fabrics with a heathered or marbled multicolor effect, loose wool, fibers, etc. are dyed, and the dyed products are blended, twisted, or mixed-knitted. The so-called first-order method is implemented. However, this method requires spinning, twisting, interweaving, etc. after dyeing, so heathered or marbled yarns, knitted fabrics, etc. 1! : Manufacturing takes a lot of time, and during the manufacturing process, it is necessary to change and clean the machine for each color, and waste is generated during manufacturing, which reduces the so-called production yield. production efficiency decreases. Therefore, in the above-mentioned yarn dyeing method, it is important to meet the current demands for short cycles, small quantities, and a wide variety of products.

As a method for dealing with the above-mentioned problems in the prior dyeing method, a -bath multicolor dyeing method has been carried out. This includes, for example, the multichrome method in which wool fibers pretreated with chromate are mixed with untreated wool fibers, and the method introduced in the cation fund in which deep dyed wool fibers are mixed with untreated wool fibers.
This is a method for dyeing yarns and knitted fabrics, which are a mixture of two types of fibers with different affinities for the same dye, such as treated wool fibers and untreated wool fibers, in one bath. In addition to the above methods, wool fibers can be deep dyed by removing scale from the wool fibers using an oxidizing agent such as a chlorine compound or peroxide, and by making it easier for the dye to penetrate, and by dilute ammonia treatment containing sodium chloride. There are other amine treatment methods. Resist dyeing is also a means of reducing the affinity of wool fibers for dyes, and resist dyes such as aminochloroallyl compounds (Sand Space S1 Sand Space R: Sanding) are used to leave white marks in the textile printing field. ing.

As mentioned above, the conventional one-bath multicolor dyeing method is as follows.
This is due to the mixture of two types of wool fibers that have different affinity for dyes, but wool fibers generally have a w & fiber length of 60~60.
99M1! Because the wool fibers are very long, it is difficult for the two types of wool fibers to mix evenly, and although the product after dyeing does have a marbled tone with a two-color effect, the uniformity of the marbling is poor, making it difficult to mix the two types of wool fibers uniformly. It lacks the luxurious feel that is characteristic of textile products, and its product value is low.

Furthermore, with the above-mentioned deep dyeing treatment methods for wool fibers, there is a limit to the increase in affinity and bonding strength with dyes. It is very difficult to block the dye, and it is difficult to completely prevent dye staining.

Means for Solving the Problems In order to solve the above problems, we have the multicolor effect of the present invention. The manufacturing method for wool w & textile products involves mixing wool fibers that have been resist-dyed with a polyhydric phenol compound, wool fibers that have been treated to introduce cationic groups with a quaternary ammonium salt compound, and untreated wool fibers. The product is then dyed with an anionic dye in one bath.

In the present invention, wool fibers include ordinary wool fibers,
It includes animal hair fibers such as cashmere, mohair, and angora, and wool fiber products refer to yarns and knitted fabrics.

In the present invention, wool fiber products are formed from fibers that have been subjected to resist dyeing treatment using a polyhydric phenol compound, fibers that have been treated to introduce cationic groups using a quaternary ammonium salt compound, and untreated fibers. .

First of all, wool fibers treated with polyhydric phenol compounds block the amino groups that serve as dyeing sites, preventing the dye from being dyed. The resist dyeing effect is extremely excellent, and regardless of the amount of residual dye in the dye bath, dyeing does not occur and white remains. Suitable polyhydric phenol compounds include glutinous acid, tannic acid, and synthetic tannins. After treating wool fibers with an aqueous solution, they are treated with stannous chloride, aluminum hydroxide, and other chromium, copper, cobalt, antimony, etc. By fixing with an inorganic metal compound, a complete resisting effect can be obtained. Note that the resist dyeing treatment can also be performed on already dyed W&fibers, and can impart resisting properties to subsequent dyeing.

Next, cationic groups are introduced into the wool fibers treated with the quaternary ammonium salt compound, which gives them a very crystalline affinity for anionic dyes that cannot be obtained with conventional deep dyeing treatments. Granted. Generally, for untreated wool fibers,
Normal anionic dyes are dyed after 60°CfrrI and are completely dyed by treatment at 100"C for 30 to 60 minutes, whereas wool fibers with cationic groups are dyed at 60°C frrI.
The dyeing starts at around 70'C and is almost exhausted at 70-80'C, so that it has a good affinity, and as a result, a great deep dyeing effect appears. In addition, when cationic dye fibers and untreated fibers coexist in the same dye bath, anionic dyes first dye the cationic dye fibers at low temperatures, and the dyeing speed, equilibrium dyeing, and dyeing amount are large. Most of the fibers are dyed and dyed deeply at 70-80"C, while the coexisting untreated fibers are dyed at 60"C.
The residual dye in the dye bath starts dyeing from the front and back, but since most of the dye is dyed onto the cationic group-introduced fibers, the dye q concentration in the dye bath is low at the time when dyeing begins on untreated fibers. , even if it is exhausted, it is pale in color. Therefore, when cationic group-introduced fibers and untreated fibers coexist in the same dye bath, when the dye concentration in the dye bath is low, the difference in shade after dyeing is large, and as the dye concentration increases, The amount of residual dye at 80°C also increases, and the difference in shade becomes smaller. Examples of the quaternary ammonium salt compounds used in the present invention include 2.3-epoxypropyltrimethylammonium chloride, 3-
These include chloro-2-hydroxylprohylttrimethylammonium chloride, 2,3-functional poxypropylmorpholinium chloride, epoxypropyltrimethylammonium bromide, 2,3-epoxypropylbiverazine, etc., and wool fibers are treated with an aqueous solution.

The above-mentioned resist dyeing treatment using a polyhydric phenol compound and cationic group introduction treatment using a quaternary ammonium salt compound are both carried out in the form of loose hair, top, or thread, depending on the requirements. When the above-mentioned treatment is performed on loose wool or top, both of them and the untreated top are mixed in a predetermined proportion and spun by a conventional method, and the resulting yarn or the fabric knitted and woven using the same is treated with anion. Dyeing in one bath with dyes. In addition, when the above-mentioned treatment is applied to the yarn, the mixed twisted yarn of both treated yarn and untreated yarn, or the knitted fabric made by mixing and weaving the above-mentioned double treated yarn and untreated yarn, is treated with anionic dye in one bath. dye.

Examples of anionic dyes used in the present invention include acidic dyes, 1:2 type metal-containing dyes having a sulfamide group or sulfomethyl group, dark alloy dyes having a sulfone group, reactive dyes, chromium dyes, etc. Dyeing The method is the same as the amount of auxiliary agent used, the dyeing cycle, etc., as in the case of ordinary dyeing of wool fiber products, except that the temperature at the start of dyeing is changed from the usual 40 to 50°C to 30'C.

Function In the present invention, wool fibers subjected to resist dyeing treatment with a polyhydric phenol compound as described above and wool wj subjected to cationic group introduction treatment with a quaternary ammonium salt compound are used.
When wool fiber products such as yarns and knitted fabrics made by mixing T-fibers and untreated wool fibers are dyed in one bath, the cationic group-introduced fibers are dark colored, the untreated fibers are medium colored, and the dyeing is further improved. The dyed fiber becomes a white color, resulting in a heather tone or x4 tone product with a three-color effect of light, medium and light, which is difficult to mix uniformly and lacks a luxurious feel due to unevenness. Compared to a two-color mixed product, by mixing three types of fibers, it has a three-color effect of A1 medium and light (white), and has good uniformity and a luxurious heathered or marbled tone. of products are obtained. Furthermore, by applying a resist dyeing treatment to already dyed fibers and mixing such resist dyed fibers, it is also possible to obtain a product with a multicolor effect of four colors. In addition, if you weave and weave the cationic group-introduced fiber yarn in stripes or twills using a yarn that is a mixture of the three types mentioned above, and then dye the next item, you can obtain a special luxurious product with a subdued M tone. It will be done.
