DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber material for jeans, and more particularly to a fiber material for jeans suitably used for all season type jeans.

[0002]

2. Description of the Related Art Conventionally, various fiber materials have been used as fiber materials for jeans, but usually, cellulose fiber materials such as cotton denim, rayon, and purified cellulose are used. Indigo blue cotton denim jeans, which is typically used as a jeans color, is provided by dyeing these fiber materials with, for example, an indigo dye.

[0003]

However, these jeans are often not worn in midsummer and midwinter. This is due to the fact that these jeans become stuffy when worn in the middle of summer, and they are cold and poor in heat retention when worn in the middle of winter. Further, the conventional jeans also have a problem in that when wet with water, the water-wetted portion easily becomes stained and hardly dries, thereby impairing the appearance.

[0004] On the other hand, jeans have a unique color such as blue, light blue, black, and white, unlike ordinary clothes and pants, and it is particularly required that these colors be sufficiently exhibited. Therefore, even if an all-season type jeans that can be worn both in the summer and in the winter is provided, it would not be preferable as a fiber material for jeans if the peculiar color of the already established jeans is offset. hard. Furthermore, in terms of this hue, in the case of a typical blue jeans, the usual dyeing is difficult to produce a bluish blue in the conventional dyeing, and the bluish blue is inevitable. In addition to the above-mentioned problems, a fiber material for jeans having a final dyeing color capable of producing a certain blue color has been particularly desired.

[0005] An object of the present invention is to provide an all-season type jeans fiber material and jeans that can be worn in midsummer and midwinter while retaining the unique color of jeans.

Another object of the present invention is to provide an all-season type jeans fiber material and jeans which retain the color peculiar to the jeans and hardly stain the water-wetted portion.

It is a further object of the present invention to provide an all-season type jeans fiber material and jeans which can exhibit a bluish blue while retaining the unique color of jeans.

[0008]

As a result of intensive studies to solve the above problems, a cellulose fiber material dyed with a dye is treated with an aqueous solution of a complex salt compound represented by the following general formula (1). Also, they have found that jeans woven from the same fiber material can solve all of the above problems. The present invention is a fiber material for jeans in which a cellulose fiber material dyed with a dye is treated with an aqueous solution of a complex salt compound represented by the following general formula (1).

A complex salt compound represented by the above general formula (1) (R represents an alkyl group or alkenyl group having 2 to 22 carbon atoms, X represents a halogen, and M represents a metal capable of forming a complex salt). Is a compound that exhibits a water-repellent action, but unlike known wax-based water-repellents and fluorine-based water-repellents, it does not coat the entire fiber surface but instead dyes, especially indigo dyes, reactive dyes, This is presumably because it selectively reacts with cellulose fiber treated with either a dye or a vat dye to exhibit a water-repellent effect. That is,
The complex salt compound represented by the general formula (1) dissociated in water exhibits cationic activity, and is thereby electrically adsorbed on the surface of an anionic cellulose fiber. It is considered that covalent bonds occur and fix the cellulose fibers. In particular, when the cellulose fiber is treated with any of indigo dyes, reactive dyes, direct dyes, vat dyes, these dyes exhibit anionic properties, and together with the anion-on activity on the cellulose fiber surface, the above general formula The complex salt compound represented by (1) is well fixed, whereby the complex salt compound is bonded between the cellulose fibers treated with the dye and sufficiently exhibits water repellency and moisture permeability. Therefore, even if jeans woven with the cellulose fiber material are worn in the summer, stuffiness is sufficiently prevented. In addition, repulsion by a complex salt compound represented by the above general formula (1) (R represents an alkyl group or alkenyl group having 2 to 22 carbon atoms, X represents a halogen, and M represents a metal capable of forming a complex salt). The water action eliminates the water absorbed by the conventional fiber material, so that it does not feel cold even when worn in the middle of winter, and exhibits heat retention.

The most important point here is that the cellulose fiber material dyed with a dye is converted into a complex salt compound represented by the general formula (1) (R is an alkyl group or alkenyl group having 2 to 22 carbon atoms, and X is H represents a halogen. M represents a metal capable of forming a complex salt.) Does not impair the peculiar color of jeans.

Rather, a cellulose fiber material dyed with a dye is mixed with a complex salt compound represented by the general formula (1) (R represents an alkyl or alkenyl group having 2 to 22 carbon atoms, X represents a halogen, and M represents a complex salt. In the case of a fiber material for jeans and a jeans treated with an aqueous solution of (a), a portion wetted with water does not become stained and exhibits a durable water repellent action.
