Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for producing yarn-dyed textile products using cationized cellulose fibers.

Prior Art Conventional 1 Methods for obtaining yarn-dyed cellulose fiber products include yarn dyeing and pretreatment of cellulose fibers with a cationizing agent to increase the absorption rate for anionic dyes.
Two methods are well known to facilitate deep color dyeing.

However, if the dye selection and dyeing method are appropriate, the yarn dyeing method can produce products with good fastness and less hot water staining and washing recontamination1, but its manufacturing cost is higher than that of the present invention. There is a drawback.

Furthermore, there are many methods for cationizing cellulose fibers, for example, Japanese Patent Publication No. 19361/1973;
No. 5-11477, Japanese Patent Publication No. 47-45628, Japanese Patent Publication No. 4B-23834, Japanese Patent Publication No. 51. -51
Publication No. 11, Special Publication No. 53-24552, Special Publication No. 5
It is disclosed in Japanese Patent Publication No. 3-2437, Japanese Patent Publication No. 53-43231, Japanese Patent Application Laid-Open No. 48-39779, and the like. However, this method not only requires an expensive cationizing agent, but also cationized cellulose fibers generally have a rough texture due to the polymer film formed on the fiber surface, and dyes with different hues. It has the disadvantage that it is difficult to obtain dyed products with clear hues, and it also adsorbs dyes that have fallen off from other dyed products during soaping of dyed products or home washing, resulting in hot water contamination, changes in hue, etc. The problem of decreased clarity was also likely to occur.

In addition, conventionally, cellulose fibers were cationized and dyed using the cationization properties, which were processed by weaving, scouring, bleaching,
Most of the products never saw the light of day for commercialization because they were not able to be commercialized into distinctive and attractive products due to poor connections with mercerization, various dyeing techniques, and masking methods.

OBJECTS OF THE INVENTION The present invention aims to eliminate such drawbacks and to provide a method for producing yarn-dyed cellulose fiber products with excellent color fastness and resistance properties using cationized cellulose fibers. purpose.

Structure of the Invention The method of the present invention involves preparing a cellulosic fiber product partially containing cellulose fibers to which β, γ-epoxypropyltrimethylammonium chloride has been reacted and fixed, a reactive dye, a 1.2-type alloy dye, The method is characterized in that the textile product is dyed with a dye selected from the group consisting of acid dyes and organic dyes, and then treated with a masking agent.

The reaction fixation of β, γ-epoxypropyltrimethylammonium chloride (hereinafter referred to as epoxy compound) to cellulose fibers is preferably carried out on cellulose fibers in the form of yarn, such as cheese yarn, conventional or beam warped yarn. It can be carried out using a cheese dyeing machine, a meat & dyeing machine or a beam dyeing machine. It can also be carried out using a warp sizing machine.

For example, in the dipping method using these dyeing machines, a reaction solution containing 3 to 10% of an epoxy compound and 1 to 3% of caustic soda is used at 70 to 100°C for about 1 hour, followed by washing with water. A cationized thread can be obtained by neutralization and drying.

In addition, in the padding method, for example, warped yarn is padded with a solution of pH 11.5-12°5 containing 5-10% of an epoxy compound at a ratio of 50-80%, dried at 50-100°C, and then A cationized yarn can be produced by treatment with dry heat or wet heat at ~150°C.

Next, the present invention dyes textile products such as woven fabrics, knitted fabrics, non-woven fabrics, etc. in which cationized cellulose fibers are used in combination with non-cationized fibers, such as woven fabrics, knitted fabrics, and non-woven fabrics, with various dyes, and This is a pre-dyed product that takes advantage of the difference in dyeability, but it is treated with a masking agent after dyeing to improve its stain resistance (complete prevention of re-contamination during washing).
This can only be achieved effectively by increasing the

The masking agent is not particularly limited, but it is preferable to use a compound having a phenolic hydroxyl group, particularly a compound represented by the general formula (where n is an integer of 2 to 6). A masking agent treatment in a bath of 5 to 2 t/A at 60 to 70'C for about 20 minutes is sufficient.

In the present invention, it is preferable that the cellulose fiber product is subjected to scouring, bleaching and mercerization prior to production, thereby significantly improving the color fastness and stain resistance of the product.

This is because scouring, bleaching, and mercerization remove epoxy compounds that have reacted with cellulose or hemicellulose that easily fall off, and also increase the reactivity of epoxy compounds. Therefore, anionic impurities are not adsorbed to the fibers, making it highly practical.

Incidentally, the method of dyeing textile products in the present invention varies somewhat depending on the type of dye.

Typical staining methods are as follows.

a) Textiles are placed in a neutral bath at 60°C containing reactive dyes for 3

The cellulose fibers are treated in a reactive dye bath at 40 to 60°C for an additional 60 minutes to react with the dye and soaped.

b) Textile products can be dyed with pH 4 dyes containing type 1.2 metal-containing dyes, acid dyes (preferably the use of milling dyes) or chromium dyes.
-6. Treat in a dye bath at 80 to 100°C for 30 to 60 minutes to adsorb the dye to the epoxy compound reaction area, and then wash with water.

C) The textile product is immersed in a dye bath containing chromium dye adjusted to pH 4 to 4.5, the temperature is gradually raised, and sodium thiosulfate is added to 0.001% (o6w, f) at around 80°C.
Add, dye for 30 minutes, wash with hot water, wash with water, and dry.

e) After the padding dyeing in d), the textile product is printed with a printing solution containing an appropriate amount of reactive dye, 2% sodium alginate, 15% A urea, and 1% sodium metanitrobenzene sulfonate. Pad the water glass, steam and soap.
