Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a beam-proofing method for textile products, particularly hydrophobic textile products, and more particularly to an improvement in a beam-proofing method using a polyvalent metal compound as a dye resisting agent.

As a related matter, as a resist dyeing method for hydrophobic fibers such as polyester fibers, a chemical resist dyeing method is known in which a polyvalent metal compound having a chelate bonding property with a dye is used as a beam resisting agent.

This type of beam resisting method provides excellent continuous printing properties, operational stability, and good resisting properties due to high-pressure steam treatment. In addition to insufficient differential color development, the product also has drawbacks such as difficulty in cleaning and removing metal compounds present on the fabric after color development, and poor beam-proofing properties. The present inventors have conducted intensive research to solve the above-mentioned drawbacks, and as a result, have arrived at the method of the present invention.

That is, the present invention provides a hydrophobic textile product with a resisting paste made by adding 5 to 2% by weight of an o/pattern oil emulsion to a beam-proofing paste containing a polyvalent metal compound as a beam-proofing agent. After printing the pattern and then overprinting with printing paste,
It is characterized by dye fixation by high temperature steam method or thermosol method. When using the method of the present invention, the dye fixation rate after drying in resist printing by the so-called wet-on-wet method, in which a resist fabric containing a polyvalent metal compound is printed and then a printing paste is printed in a wet state, can be improved. In fixing by high-temperature steam method or thermosol method, in which moisture in the fabric is hardly expected to contribute to the improvement, the o'w type oil emulsion component in the beam-proofing paste prevents the rhombic dye from turning into a lake, and also makes it possible to It can promote solubilization and improve dyeing and elucidation properties.

In addition, in combination with o'w type oil emulsions, guar gum or locust bean gum type resist dyes that use polyvalent metal compounds as resist dyes and tend to have poor desizing properties in resist dyes that are fixed by high temperature steam method or thermosol method. Another major feature is that it is possible to reduce the amount of lake agent used, and the deretention layer can be significantly improved, and the ability to wash and remove polyvalent metal compounds remaining on the printed fabric can be improved. Furthermore, the combined use of an o/W type emulsion also improves the resist dyeing effect, which is quite surprising when considering also the increase in dyeability of the differential color dye. It is also noteworthy that the effect of the combined use of o'w type emulsions is not observed at all in normal pressure to high pressure steam methods, but is an effect unique to high temperature steam methods or thermosol methods. The polyvalent metal compounds used in the present invention include polyvalent metal salts and polyvalent metal hydroxides such as sulfates, nitrates, acetates, carbonates, halides, and hydroxides such as copper, barium, nickel, and zinc. These examples are used alone or in combination of two or more.

Considering the chelate bonding ability of polyvalent metal compounds with dyes, the stability of dyes and multipliers, etc., alkaline and acidic polyvalent metal compounds are used in combination so that the pH of the resist-dyed fabric is approximately neutral or slightly acidic. It is preferable to use a polyvalent metal salt and a polyvalent metal hydroxide in combination. The pH can be adjusted by adding an acid or alkali if desired, but it is stable to adjust the pH to 6 to 9 by adding an excess of polyvalent metal hydroxide to the polyvalent metal salt and adding an organic carboxylic acid. It is particularly preferred from the viewpoint of properties, beam-proofing effect, etc. The amount of the polyvalent metal compound used is usually 10 to 5 parts by weight, preferably 20 to 35 parts by weight, per 100 parts by weight of the resist dyeing lake. Thickening agents used in resist dyeing pastes and printing pastes are preferably ones that have good compatibility with polyvalent metal compounds, and usually include ether chemical fiber powder, etherified cellulose, guar gum, locust bean gum, polyvinyl-based thickening agents, etc. used.

In addition, up to 5% by weight of a surfactant can be added to the beam-proofing paste from the viewpoint of stability, but amphoteric surfactants are particularly preferred from the viewpoint of stability, beam-proofing properties, etc.
Furthermore, the o'w type oil emulsion used in the present invention includes mineral oils such as turben oil, animal and vegetable oils,
30 to 80 parts by weight of synthetic oil or the like is emulsified with 60 to IQ parts by weight of water using 1 to IQ parts by weight of an emulsifier, and mineral oil is particularly preferred. Examples of the emulsifier used include polyoxyethylene mono- or diacylate, polyoxyethylene alkyl ether, polyoxyethylene sorbitan monoacylate, pluronic, tetronic, etc., and polyoxyethylene diacylate is particularly preferred.
The amount of o/W type oil emulsion added is usually 5 to 2% by weight, but it is around 15% by weight, that is, 1% by weight.
Particularly preferred is a range of more than 0% by weight and less than 20% by weight. If it exceeds 2% by weight, the film strength of the resist dyeing paste decreases, resulting in problems such as stamping, glue flying, and dust during the printing process. The textile products printed with the beam-proofing paste and the printing paste are then dried and fixed using a high-temperature steam method or a thermosol method, followed by finishing by usually demetallizing, washing, and soaping.

The conditions for high temperature steam are usually 150 to 190 qo and 5 to 1
About 5 minutes is enough, and the thermosol conditions are usually 1
A temperature between 60 and 12 degrees Celsius at 90 to 220° C. is sufficient. In the present invention, dyes that can be used as beam barriers include dyes that have a chemical structure that can be chelated with polyvalent metals, dyes that are dispersed with a dispersant that interacts with polyvalent metals, and eliminates the dispersion effect, etc. Specifically, anionic group-containing dyes, disperse dyes, disperse dyes dispersed with anionic activators that can react with polyvalent metals, complexes of anionic dyes and cationic compounds, and complexes of cationic dyes and anionic compounds are exemplified. Ru.

However, disperse dyes having a chemical structure that is particularly capable of reacting with and chelating polyvalent metals are preferred, such as C.I. 1.

In addition, the differential color dyes used in Haruiro Bōriō include dyes that do not react with polyvalent metals or have low reactivity, but in particular, disperse dyes that do not react with polyvalent metals and do not chelate or do not easily react with them are preferred, such as C. 1.

As hydrophobic fiber products to which the present invention is applied, particularly preferred are knitted fabrics, rugs, nonwoven fabrics, synthetic papers, fiber sheets, etc. containing hydrophobic fibers such as polyester, polyamide, and acetate.

However, hydrophilic fiber products such as cellulose and polyvinyl alcohol can also be applied by imparting beamability to disperse dyes through pre-treatment to make them hydrophobic with hydrophobic alkoxymethylated melamine, etc. through etherification or esterification. . It goes without saying that it can also be thinly applied to modified fiber products such as ionic dye beam-modified polyester and flame-retardant modified polyester.

The present invention will be explained below with reference to Examples.

Note that parts and % in the examples mean parts by weight and % by weight. Example 1 On a 100% polyester textured yarn fabric (suede), the following beam-proofing glue arc (present invention) and legs (comparative example) prepared using the following beam-proofing agent composition and O/W type oil emulsion were flattened.

As a result, the present invention using resist dyeing lake ■ not only has excellent dyeability of differential color dyes and demetalization property after dye fixation, but also has many features such as improved resist dyeing effect, and is extremely We provide colored and resist dyed products with high commercial value.

On the other hand, in the comparative example in which no o/w emulsion was used, the color development of the differential color dye was insufficient, and furthermore, the demetallization property by washing was poor, resulting in a colored resist-dyed product with poor clarity.

Furthermore, when fixing was performed using high-pressure steaming instead of high-temperature steaming, no effect was observed when using the o-W-type emulsion in combination, and the effect was unique to fixing using high-temperature steaming. Example 2 On a 100% polyester textured yarn fabric, the self-resist dyeing paste prepared using the resist dye composition of Example 1 was printed in a pattern using a flat screen printing machine.

Next, a printing paste with the following formulation was overprinted on the entire surface, dried, and then steamed at 170° C. for 12 minutes using a high-temperature steamer, followed by washing, soaping, washing, and drying.

As a result, when O'　-type oil emulsion is added in an amount of more than 10% to less than 20% in 5-20% increments to the beam-proof paste, the color field of the differential color dye and the colored resist dye with extremely excellent clarity are obtained. Goods were obtained.

On the other hand, when the o/w type oil emulsion was not added, the color field and sharpness of the differential color dye were insufficient. Moreover, when it is added in an amount of 20% or more, the strength of the film decreases, causing problems such as tree flying and dust. Example 3 The following resist beam paste prepared using the resist dye composition of Example 1 was printed in a pattern on a 100% polyester processed yarn knitted fabric (interlock) using a screen printing machine.

On the other hand, in the comparative example using the beam-proofing paste {B', the beam-proofing effect was poor, and the metal removal property by washing was also insufficient, so that a completely white beam-proofing product could not be obtained.
