Problems solved by technology

However, there is no case where the cellulose of bamboo or cultivated bamboo is taken out, fiberized, and formed into long fibers to make woven or non-woven fabrics.
[0004] In addition, although polyester synthetic fibers are combined with short-fiber spun yarns made of bamboo to obtain textiles that are effective in stretchability and touch, there is no description of filaments (see Non-Patent Document 2 )

Embodiment 1、 comparative example 1、2

[0073] Using a repulped raw material that pulps bamboo produced in China, dips the pulp in caustic soda, pulverizes and refines the α-cellulose component, and spins rayon filaments 130dtex- The composite yarn of 30 is carried out the silk cake of spinning trial production silk cake unit weight 525g. As a comparison, a 120dtex-30 multifilament produced by a stretch spinning method and a 84dtex-24 multifilament produced by a continuous spinning method using cotton linter pulp as a raw material were used. Examine the filaments produced by centrifugal spinning, scoured cakes, and continuously spun bobbins. As a result of observing the cross section, comparing the raw material of cotton linter pulp and the filaments using bamboo pulp, there is no big difference in the unevenness of the surface, but some sections of the filaments made of bamboo are flat and slightly white. A little yellow. Table 1 shows the results of the measurement of physical properties.

[0074] The multifila...

Embodiment 2～10、 comparative example 3

[0080] Compared with bright filaments of 84dtex24 filaments using bamboo raw material pulp by the centrifugal spinning method of viscose rayon method, various bright filaments of rayon filaments (84dtex24 filaments) using wood pulp as raw materials were trial-produced. fabric. As a result of the measurement of α-cellulose, β-cellulose and other components using the above-mentioned chemical analysis of the two rayon filaments used, the composition of the filaments made of bamboo is: α-cellulose 87.5% by weight, β-cellulose 10.6% by weight of cellulose, and 1.9% by weight of other components. On the other hand, the filaments made of wood are: 90.8% by weight of α-cellulose, 9.0% by weight of β-cellulose, and 0.2% by weight of other components.

[0081] In Examples 2 and 3, 84dtex-24 bamboo raw material filaments are used for the warps, which are not compounded with other precursors, and not twisted in the same direction, and are sent to rapier looms for sizing and warping. In ...

Embodiment 4、5

[0083] Embodiment 4,5, warp adopts warping bamboo raw material long filament (84dtex-24 long filament) along S and Z direction by twist number 1500T / M and carry out 2 silks of twisting in the same direction alternately, warp silk shaft Mounted on a winding loom. In the weft weaving (A) the fabric using the same strong twisted yarn used in the warp, (B) the composite crimped yarn 56dtex24 filament of PET / PTT bimetallic composite spinning is the same bamboo material used in the warp After the filament 84dtex-24 filament is plied, use a two-for-one twister to implement 1500T / M twisted yarns in the same direction along the S direction and the Z direction. Every 2 twisted yarns are used alternately to weave interwoven fabrics (plain georgette and crepe Georgette), for dyeing and finishing.

[0084] Dyeing was carried out on a normal plain-weave finished fabric (Example 4) and a fabric whose surface was changed by drum drying (Example 5).

[0085] Drum-dried products, the surface ...

Abstract

In view of the demand to replace wood pulp to preserve forests which is brought about by the recent trend to preserve natural resources from the terrestrial warming or the environmental pollution, the present invention aims to provide a yarn using cellulose-based filament yarn made from bamboo. The above-mentioned object can be achieved by a fiber yarn which is a yarn containing a filament of cellulose-based fiber made from a bamboo having a thickness of 10 to 600 dtex and number of twist of 0 to 3,000 T / M.

Description

technical field [0001] The present invention relates to cellulose-based fiber yarns made of bamboo and fabrics constituting woven or non-woven fabrics using the fiber yarns. technical background [0002] So far, as raw materials used for fabrics of woven fabrics and non-woven fabrics, natural fibers have been used as raw materials produced by cultivation and breeding, and as chemical fibers, natural raw materials such as cellulose-based regenerated fibers, semi-synthetic fibers, protein-based fibers, Synthetic fibers made from coal and petroleum account for more than half. However, in recent years, environmental pollution and global warming due to an increase in CO2 due to deforestation for use of fibers and an increase in industrial waste generated from coal and petroleum-based raw materials have become major problems. [0003] In order to solve this problem and protect the global environment, research and development are being carried out to use biomass resources (non-pet...
