JPH04174782A - Deep-color dyed woolen textile product and production thereof - Google Patents

Abstract

PURPOSE:To obtain the subject textile product with an unconventional deep color tone by forming a deepened color film composed of a fluorine compound and a nonionic surfactant on the surface of a woolen textile product. CONSTITUTION:Wool fiber is previously subjected to oxidation treatment to partially remove surface cuticular layers and a treating solution containing a fluorine compound (e.g. tetrafluoroethylene-hexafluoropropylene copolymer) and a nonionic surfactant is then applied to the surface of a dyed woolen textile fabric and dried to form a deepened color film assuming a deep color of <=14 L value. Thereby, a woolen textile product of a deep color tone which is not conventionally available can be obtained. For example, an ethylene oxide addition type polyoxyethylene alkyl ether can be exemplified as the aforementioned surfactant.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deep-colored dyed wool fiber product that exhibits a deeper color than conventional products even if the color is the same, and a method for producing the same.

[Conventional technology]

In general, even if the fabric is of the same color, the deeper the color, the higher the commercial value, so dyeing the fabric to a deeper color has become a major issue in deep color dyeing. In particular, there is a desire to dye the black woolen fabrics used for formal wear, etc., to a black color similar to the color of a crow's wet feathers. To achieve such deep color dyeing, there is a limit to simply changing the concentration of the dye or the combination of dyes, and various attempts have been made to separately apply deep color processing to make the color developed by the dye look even deeper. ing.

For example, a method has been proposed in which a compound with a low refractive index of 1.45 or less is adsorbed onto the surface of a textile product to reduce the amount of light reflected from the textile product, thereby making the dyed color appear deeper. (Japanese Unexamined Patent Publication No. 55-26232).

[Problem to be solved by the invention]

However, this method is mainly aimed at improving the color development of polyester textiles, which have poor color development, and even if this method is applied to wool-based textiles, it will not be possible to achieve a significant degree of deep coloring. The reality is that it has not been possible to finish the black of woolen fabric to a deep black that resembles the wet color of a crow.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a wool-based textile product dyed in a deep color and a method for producing the same.

[Means to solve the problem]

In order to achieve the above object, the present invention aims to form a deep-colored film consisting of a fluorine compound and a nonionic surfactant on the fiber surface of wool-based textiles so that the fibers exhibit a deep color with an L value of 14 or less. The first aspect is deep-colored dyed wool textiles, which are dyed and then treated with a deep-coloring treatment solution containing a fluorine compound and a nonionic surfactant. The second gist is a method for producing a deep-colored dyed wool-based fiber product in which a deep-colored film made of a fluorine compound and a nonionic surfactant is formed on the surface of the product.

[Effect]

That is, as a result of a series of studies conducted by the present inventors on a method for dyeing wool-based textiles in deep colors, the inventors added a nonionic surfactant to the fluorine compound conventionally used as a deep coloring agent. We discovered that by forming a mixed film of both on the fiber surface, a much deeper color can be obtained than when treated with the above fluorine compound alone, that is, a product with an L value of 14 or less. We have arrived at the present invention.

In addition, in the present invention, the L value refers to a color difference meter (ND-101
DC type 2 (manufactured by Nihon Heavy Industries Co., Ltd.), and the lower the value, the darker and deeper the color.

Next, the present invention will be explained in detail.

In the present invention, a deep-colored coating consisting of a fluorine compound and a nonionic surfactant is formed on the fiber surface of a wool-based textile product so that the product exhibits a deep-colored color with an L value of 14 or less.

The above-mentioned wool-based fiber products include wool yarn made of 100% wool fiber, blended yarn made by blending wool fiber with other fibers such as silk fiber,
Alternatively, it refers to woven fabrics made of these yarns, two-knit fabrics, fabrics that are mixed and knitted with wool yarn and other yarns, etc.

When dyeing the above-mentioned wool-based textiles using various dyes, auxiliary agents, etc. to obtain an L value of 10 to 11, the concentration of the dye is 8% 0-r (weight relative to the weight of the textile). (the same applies hereinafter) or more is preferable.

In addition, examples of the fluorine compound supplied to the fiber surface of the wool-based fiber product include tetrafluoroethylene-hexafluoropropylene copolymer, polybentadefluorooctyl acrylate, 1-fluoroethylene, and polytrifluoroethylene acrylate. 1-, polytrifluorochloroethylene.

Examples include poly I-lifluoroethyl methacrylate. These fluorine compounds can be used alone or in combination of two or more.
The two may be used together. The amount used is preferably set to 0.1 to 1% by weight, and particularly preferably 0.2 to 0.6% by weight. It is.

If it is less than 0.1% by weight, the effect of deepening the color will be weak, and if it exceeds 1% by weight, the film will become too thick and will be physically fragile, and it will be easy to get streaks when rubbed with your fingernails. (You can see the middle.

Furthermore, examples of the nonionic surfactant used with the above-mentioned nitrogen compound include the following, which are usually used as antistatic agents. For example, as an ethylene oxide addition type, polyoxyethylene alkyl ether,
Ether-type nonionic surfactants such as polyoxyethylene alkylphenyl ether, polyoxyethylene styrylphenyl ether, propylene oxide-ethylene oxide block polymer (Pluronic type), sorbitan fatty acid partial ester, glycerin fatty acid partial ester, polyglycerin (degree of polymerization 2-10) fatty acid partial ester, pentaerythritol fatty acid partial ester,
Examples include fatty acid ester type nonionic surfactants such as polyethylene glycol fatty acid diester, polypropylene gelicol fatty acid monoester or diester, and sucrose fatty acid ester partial ester, as well as those obtained by adding ethylene oxide to partial esters of these. . These nonionic surfactants may be used alone or in combination of two or more. And the amount used is
It is preferable to set the amount to be 0.1 to 2.5% by weight, especially 0.1% to 2.5% by weight. ~0.5
Particular preference is given to fixing the weight percentage. That is, 0
．． This is because if it is less than 1% by weight, the deep coloring effect is weak, and if it exceeds 2.5% by weight, the darkening effect tends to be impaired.

In the present invention, using the above-mentioned fluorine compound and nonionic surfactant, wool-based textiles can be dyed in a deep color, for example, in the following manner. That is, first, a wool-based textile product is dyed under conditions suitable for its appearance, and then,
An aqueous solution (deep coloring treatment liquid) containing the above-mentioned fluorine compound and nonionic surfactant in a predetermined ratio is prepared, and this treatment liquid is applied to the above-mentioned dyed wool-based textile product and then dried.

In this way, a deep-colored film is uniformly formed on the fiber surface by the fluorine compound and the nonionic surfactant, and a wool-based fiber product exhibiting a deeper color than that produced by the dye can be obtained. The degree of deep coloring of the above-mentioned deep color dyed products varies depending on the hue given by the dye, the type of fiber, the yarn, the two-knit woven fabric, etc.
% of georgette fabric is dyed black according to the above method, it is possible to reduce the L value to 11.75 or less. In addition, 13% for Boblin made of 100% wool.
．． 85 or less, and 12. for Toskin made of 100% wool.
It is possible to reduce the number to 13 or less.

Therefore, compared to conventional dark-dyed wool-based textile products, we can provide products with much deeper colors, and in particular, we can provide black clothing that is close to the "crow's wet color". can. This makes it possible to create high-value-added formal wear that is differentiated from conventional black clothing, and to meet the needs of consumers.

In addition, in the above manufacturing method, if the wool sliver, loose wool, top, etc. of the wool-based textile product is oxidized with chlorine or oxygen prior to the dyeing treatment, -
Deep color dyeing can be done effectively in layers. Examples of the oxidation treatment method include chlorine oxidation (usually referred to as "chlorination") using a known chlorine processing machine. This method uses chlorine gas and hypochlorous acid (
This method is a method of destroying cystine and peptide bonds on the surface scale of wool fibers using substances such as NaOCffi to generate ions, and is well known as a shrink-proofing method for wool products. In the present invention, when performing the above-mentioned chlorine oxidation, it is preferable to set the effective chlorine amount to 1 to 6% owf. The chemical changes on the wool fiber surface caused by such an oxidation reaction are as follows.

C-0 Masa and 0 ]11 ■ Cleavage of peptide bond R-NH-C-RR-NH3 ■ 10○0 Anionic and cationic groups are generated on the OC-1 plane, increasing ionic bonding ability and improving wettability. improves.

By the way, the critical surface tension of normal wool fiber is 40-45.
However, the above modification can increase the critical surface tension to 55 dyne/cm or more. Therefore, when forming the deep-colored coating, the fluorine compound and the nonionic surfactant easily diffuse onto the wool fiber surface, making it possible to form a uniform and strong coating.

Next, examples will be described together with comparative examples.
