BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described in detail.

In the method for producing a textile product of the present invention, first, a step of forming a bamboo material into chips and extracting a dye in boiling water is carried out.

As the above-mentioned bamboo material, felled bamboo material can be used as it is as chips without removing branches and leaves or peeling the outer skin. Of course, the branches and leaves may be removed or the outer shell of the bamboo material may be peeled off by an appropriate method such as manual work or a parking drum. Also, as the bamboo material,
Not only felled bamboo but also bamboo shoot peeled from bamboo shoots can be used. Bamboo and bamboo shoot skin can be used alone or in combination.

For chipping, a machine called a wood chipping machine is used to sprinkle the side surface of the bamboo material against natural sandstone or an artificial rotary whetstone while chipping it,
A crusher such as a so-called turbo mill can be used.

Next, the chipped bamboo material is boiled in boiling water for a predetermined time to extract the extract of the bamboo material as a dye. Extraction of the extract can be performed, for example, by removing the bamboo material from water obtained by boiling the chipped bamboo material and concentrating the extract dissolved in the residual water. Further, it can be extracted by taking out the insoluble extract floating in the residual water, or collecting the steam generated from the opening of the boiling pot and distilling it to take out the volatile extract.

Then, a step of producing a bamboo-derived fiber is carried out by dissolving the bamboo raw material into raw bamboo, which is made into chips, and spinning the extracted cellulose.

That is, first, after the dye is extracted, the extracted residue is digested with an alkali solution of sodium hydroxide-sodium sulfide or a solution of sulfurous acid-hydrogen sulfite to dissociate the fibers to obtain bamboo pulp. This bamboo pulp is refined and bleached if necessary.

The natural cellulose in the bamboo pulp is alkali-treated with caustic soda to give alkali cellulose, which is then squeezed and crushed and left at an appropriate temperature for 2-3 days to lower the degree of polymerization.

Then, the above-mentioned alkali cellulose is reacted with carbon disulfide to prepare a cellulose derivative, which is dissolved in an alkaline solution to prepare a raw solution of bamboo viscose. After this bamboo viscose is aged for 2 to 4 days, wet spinning is performed from the spinneret in an acidic bath, and while the fibers are being formed, a chemical reaction is performed to regenerate cellulose to obtain bamboo-derived fibers. The bamboo fiber spun in this manner is stretched with a roller, cut, crimped, and then subjected to post-treatments such as washing with water, desulfurization, bleaching and oiling to obtain staples.

A step of producing a bamboo-derived yarn by spinning the staple-shaped bamboo-derived fiber is performed.

In the spinning step, a cotton-opening machine and a cotton-blowing machine are used to perform cotton-opening and cotton-blowing, respectively, to form a mat-shaped wrap. This wrap is carded with a card machine to align the direction of the fibers and remove short fibers and nep to form a sliver, which is a fiber bundle. In the opening and batting steps, when the cotton of bamboo-derived fiber is packed in a bale shape, the fiber is a hard lump,
It is necessary to loosen it, and when it is supplied to the carding process in the cotton-like state, it is not necessary to open or waft it. Further, when the bamboo-derived fiber is supplied in the form of cotton, not only in the form of wrap, but also chute cotton may be supplied to the card machine together with the air flow.

The card machine used in the carding process is
Depending on the fiber length of the cotton to be carded, a flat card can be used for relatively short short fibers, and a roller card can be used for relatively long fiber lengths.

The card sliver carded with a card machine is
If necessary, combing is performed to remove short fibers to form a comb-river. By performing this combing, short fibers having a relatively short fiber length, nep, contaminants and the like are removed, and a sliver is formed from fibers having a relatively long fiber length. Therefore, the strength of the yarn is increased, and a fine yarn can be obtained even when spinning a fine count yarn.

The above-mentioned card sliver or comb sliver is put on a kneading machine, and for example, about 6 to 8 are bundled into 6 to
By stretching the sliver 8 times, the sliver is made uniform with less unevenness. This drawing step is repeated a plurality of times as necessary to improve uniformity.

The sliver obtained as described above is then subjected to a roving process in which the sliver is subjected to a roving machine to be further stretched and slightly twisted. This roving step is also performed a plurality of times as necessary.

The roving yarn obtained by drawing to a considerable fineness in the above-mentioned roving process is then subjected to a fine spinning machine to be extended to a predetermined yarn count thinness, and a predetermined number of twists are applied to the roving yarn. To be done. In this state, the obtained bamboo-derived yarn is a single yarn, but if necessary, it is put into a twisting machine to twist a plurality of yarns.

The spinning machine used in the above spinning step may be a ring spinning machine or a mule spinning machine, if necessary. The ring type spinning machine is suitable for efficient production of strong and strong twisted yarns, and the mule type spinning machine is suitable for production of textured yarns with less uneven twist and thickness. Further, in the case of thick count yarn, an air spinning machine can be used.

The bamboo-derived yarn thus obtained is subjected to post-treatments such as gas baking and bleaching to remove fluffs, if necessary. In addition, dyeing may be performed in the yarn state. At the time of this dyeing, the dye extracted from the above-mentioned bamboo material can be used.

Then, a step of producing a bamboo-derived fabric such as a woven fabric or a knitted fabric using the bamboo-derived yarn is performed.

When a bamboo-derived cloth is obtained as a woven fabric, bamboo-derived yarn may be used for both warp and weft, or bamboo-derived yarn may be used for either warp or weft and mixed with other yarns. You may do it. For example, yarns other than bamboo-derived fibers such as cotton yarns, silk yarns, and synthetic fiber yarns can be used as warp yarns, and bamboo-derived yarns can be used as weft yarns. Conversely, weft yarns such as cotton yarns, silk yarns, and synthetic fiber yarns can be used. Bamboo-derived yarn can be used as the warp yarn by using a yarn other than the origin fiber. In particular, a woven fabric product using a bamboo-derived yarn as a weft yarn has relatively high tear strength and good results can be obtained. Further, in this case, by using cotton threads as the warp threads, hygroscopicity and a soft touch can be obtained. In addition, if silk threads are used for the warp threads, excellent luster and drapability can be obtained.

When the bamboo-derived fabric is obtained as a woven fabric, the woven fabric structure is not particularly limited, and various kinds of fabric structures can be applied. If necessary, a special woven fabric such as a pile weave or a leno weave can be used. As the loom to be used, not only a general loom but also a shuttleless loom such as a jet or a slewer can be used, and a special device such as a dobby or a jacquard can be used.

The bamboo-derived fabric obtained as described above is
If necessary, finish treatment such as refining, bleaching, gas baking, brushing, polishing, etc., special treatment such as fluorescent whitening, sanforize, anti-wrinkle processing, waterproofing, shrink-proofing, flame-retardant, sanitizing etc. It can also be applied.

Further, the above-mentioned bamboo-derived yarn or bamboo-derived cloth is dyed with the dye extracted in the step of extracting the above-mentioned dye.

As a dyeing method, a dip dyeing method is generally used, but the dyeing method is not limited to this, and various dyeing methods such as a printing method, a casting method, a spray-dyeing method, a rubbing dyeing method and a batik dyeing method are applied. be able to.

In addition, it is excellent in hygroscopicity and breathability, and also has good antibacterial properties and deodorant properties, so that it is also comfortable to wear on clothes.

Further, since the extraction residue obtained by extracting the dye is used as the raw material bamboo, the raw material can be effectively utilized and the waste material is reduced as compared with the case where the cellulose is simply extracted from the raw material, which is extremely ecologically excellent. It becomes a thing. Moreover, most of the hides of bamboo shoots used as foodstuffs in early spring are discarded as waste materials. By using it as raw material bamboo,
