Abstract

PROBLEM TO BE SOLVED: To produce a cellulosic fiber structure such as a grandrelle yarn, a designed twisted yarn, an elastic yarn, a seersucker-like woven or knitted fabric or an elastic woven or knitted fabric without causing troubles by imparting different dyeing properties and different shrinking properties to cellulosic fibers, blending the treated fibers with non-treated fibers, and subsequently processing the blended product, wherein the troubles include the mutual entanglements of the fibers due to the wetting of the fibers, when one kind of the cellulosic fibers are cationized or processed with a resin on the production of the grandrelle yarn or seersucker-like woven or knitted fabric. SOLUTION: This cellulosic fiber structure is obtained by subjecting cotton- like, sliver-like or yarn-like cellulosic fibers to a crosslinking reaction with formaldehyde in a gaseous phase state, blending the crosslinked cellulosic fibers with non-crosslinked cellulosic fibers in a cotton-like, sliver-like or yarn-like state, processing the blended product into a spun yarn, a twisted yarn, a woven fabric, a knitted yarn, etc., suitably by a spinning means, a twisting means, a weaving means, a knitting means, etc., and subsequently treating the product with an alkali or dyeing the product.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is described in detail below.
In the present invention, first, formaldehyde is crosslinked in the vapor phase into cotton-like, sliver-like or thread-like cellulosic fibers. The term "cellulosic fibers" as used herein means natural cellulose fibers such as cotton and hemp, and regenerated cellulose fibers such as rayon, polynosic, solvent spun rayon, etc. These fibers do not necessarily have to be 100%, and other fibers. As polyester, nylon,
A synthetic fiber such as acrylic may be mixed and used. The mixing ratio of the synthetic fibers to be mixed may be any ratio, but the ratio of the synthetic fibers is preferably 50% or less. If it is 50% or more, formaldehyde does not react with the synthetic fiber in the gas phase, so that the desired effect is reduced.

In the present invention, so-called formaldehyde gas vapor-phase processing is carried out in which formaldehyde gas is adsorbed in the above-mentioned cellulosic fiber in the form of cotton, sliver or thread, and heat-treated to crosslink. At the time of vapor phase processing, first, the moisture content of the fiber is adjusted uniformly. At this time, if the moisture content of the fiber is 1% or less, the formaldehyde gas used in vapor phase processing will not be sufficiently adsorbed on the fiber, and if it is 50% or more, the acid catalyst used may cause embrittlement of the fiber. Be careful because there is. Also note that formaldehyde gas will not be adsorbed uniformly if the water is not evenly distributed in the fiber. Any means can be used to adjust the water content uniformly, but usually, the fibers are placed in a thermo-hygrostat chamber.
It is advisable to use a method of leaving it for more than an hour.

After that, in the present invention, the obtained spun yarn, twisted yarn, woven fabric, knitted fabric and the like are subjected to alkali treatment and / or dyeing. The term "and / or" as used herein is used as a term that means either or both of the two. Therefore, specifically, it means three ways of performing only the alkali treatment, only the dyeing, or dyeing after the alkali treatment. In dyeing, usual dyes for cellulosic fibers can be used, and for example, direct dyes, reactive dyes, slene dyes, etc. can be used. By performing ordinary dyeing on the above-mentioned mixed product, a step drop (shade) occurs due to the difference in dyeability between the fibers that have been subjected to the vapor phase processing and the unprocessed fibers, and the effect such as heathering and chambray is produced.

In order to obtain a soccer-like woven fabric, a stretchable yarn, or a stretchable woven fabric, the above-mentioned mixed product is subjected to alkali treatment. There are two types of alkali treatment: yarn-based alkali treatment and cloth-based alkali treatment. Examples of chemicals used for the alkali treatment include sodium hydroxide and potassium hydroxide. The concentration of alkali can be the same as that of ordinary mercer. In the case of sodium hydroxide, 10Be'-48Be 'is desirable,
More preferably, it is 20Be'-30Be '. In the case of potassium hydroxide, it is preferably 10Be 'to 48Be', more preferably 20Be 'to 30Be'. If the concentration is out of this range, the effect of sufficient alkali treatment cannot be obtained. As the alkali treatment method, a usual mercerizing method can be used, and in the case of a yarn, a mercerizing method with a ridge and a continuous mercerizing method while the yarn is running can be used. In the case of cloth, it can be processed using a continuous mercerizing machine or a pad batch method.

When the cellulosic fiber is exposed to formaldehyde in the gas phase and heat treated as in the present invention, the formaldehyde is crosslinked between the cellulose molecules and the cellulose molecules are fixed. When this is subjected to alkali treatment, the one that has been subjected to gas phase processing is difficult to swell with alkali, that is, it does not shrink due to alkali treatment, but unprocessed cellulosic fiber swells with alkali, so these two fibers are mixed-spun. ,
Alkali treatment by twisting, weaving, and knitting produces soccer-like fabrics and stretchable fabrics and threads. Also, when dyed, those that have undergone vapor phase processing are
Since formaldehyde is cross-linked between cellulose molecules, it is difficult for dyes to enter, and it is more difficult to dye than unprocessed cellulosic fibers. Therefore, if these two fibers are mixed and mixed, Staining difference occurs between
It is possible to obtain effects such as heathering and chambray.

As described in the present invention, when the cellulosic fiber is subjected to the vapor processing with formaldehyde, since the fiber can be crosslinked in the vapor phase, it is not necessary to wet or dry the fiber. When mixed with uncrosslinked cellulosic fibers without adversely affecting the twisting and weaving of the yarn, the difference in the dyeing property gives the expression of heathered yarn, chambray, etc. by post-dying, and the design. Twisted yarn or the like can be formed. Furthermore, by adding alkali treatment, soccer-like fabrics and elastic yarns,
It is also possible to obtain stretch fabrics.
