Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to a method of making pineapple fiber fabric.

[0002]

2. Description of the Related Art Pineapple fibers obtained by squeezing pineapple leaves by a suitable means, for example, by mechanically squeezing them, consist of about 80% fibrin fiber, about 10% pectin and about 10% water, and apparently about 10%. The slightly flattened and spindle-shaped constituent fiber elements having a thickness of 0.3d are filaments which are kept in a state of being stuck to each other through a large number of pectins, and other cotton,
It is significantly different from plant fibers such as hemp.

A fabric using such pineapple fiber is conventionally handcrafted by spinning and weaving, and then exposed to water.
It was produced by exposing to the sun, and was especially known as high-quality clothing in the Philippines under the name Pigna.

On the other hand, although a manufacturing method has been carried out in which pineapple fibers are spun and weaved in the same manner as in the case of cellulosic fiber cotton, there is almost no practical production.

[0005]

However, such conventional methods have various drawbacks. For example, a handicraft method can produce something valuable as a traditional craft, but the whiteness of the bleaching is insufficient, the texture is hard, there are many fluffs, the hue is limited, and it can be used for various purposes. It has a limitation that it is very limited and its productivity is extremely low.

[0006] Further, if the weaving is carried out in the same process as the ordinary cotton, the productivity is improved, but since the pineapple fibers are easily fibrillated, many fluffs are generated on the surface of the cloth, and the appearance and the wearing feeling are inferior. ..

The manufacturing method of the present invention solves the above-mentioned problems, and has less fluff on the surface of the cloth than the conventional manufacturing method of the pineapple fiber cloth, and the soft texture of the pineapple fiber It is an object of the present invention to provide a method for producing a fabric having a good wearing feeling with high productivity.

[0008]

SUMMARY OF THE INVENTION The above-mentioned object is to make pineapple short fibers and easily soluble short fibers 50:50 to 90: 1.
This is achieved by a method for producing a pineapple fiber fabric, which is characterized in that a fabric is woven using a blended yarn mixed in a proportion of 0, and then the easily soluble short fibers are dissolved and removed.

The present invention will be described in detail below.

The pineapple short fibers referred to in the present invention are 20 to 20 pineapple fibers made from pineapple leaves.
It refers to a short fiber having a fiber length of about 50 mm.

The easily soluble short fibers referred to in the present invention are short fibers which are easily dissolved and removed when treated with a specific chemical such as water or sodium hydroxide. Examples of such easily soluble short fibers include polyvinyl alcohol short fibers (eg, water-soluble vinylon short fibers), atmospheric pressure dyeable polyester short fibers, and the like, but polyvinyl alcohol short fibers are preferable. Such a fiber length of the easily soluble short fibers is preferably substantially the same as the fiber length of the pineapple short fibers used,
The fineness is preferably fine so that it can be easily dissolved and removed.

The blended yarn as referred to in the present invention means a state in which pineapple short fibers and easily soluble short fibers are substantially uniformly mixed and spun.

The above pineapple short fibers and the easily soluble short fibers must be contained in a ratio of 50:50 to 90:10. When the amount of pineapple short fibers is less than 50% by weight, the strength of the fabric after dissolving and removing easily soluble short fibers becomes weak, and when the amount of pineapple short fibers exceeds 90% by weight, the number of yarns is insufficient during spinning. Since the yarn has less entanglement, the yarn strength is insufficient, spinning becomes impossible, and fluff occurs on the surface of the obtained fabric, which is not preferable.

Then, after the cloth is woven using the blended yarn, it is melted by a method capable of dissolving and removing the easily soluble short fibers to manufacture a cloth made of only pineapple short fibers.

[0014]

EFFECTS OF THE INVENTION Since the present invention is constituted as described above, when the pineapple short fibers are spun and weaved, the easily soluble short fibers act as a protective layer, and it is possible to prevent the pineapple fibers from becoming fibrillated due to threads or the like. The generation of fluff is suppressed. In addition, since the easily soluble short fibers can be easily dissolved and removed, the soft texture peculiar to pineapple fibers is not impaired.

[0015]

EXAMPLES The present invention will be described in detail below based on examples.

Example 1 Pineapple short fibers (10-45 d, average fiber length 20-)
50 mm) 70% by weight and water-soluble vinylon short fibers (3d,
Average fiber length 30 mm) 30% by weight is mixed and spun in a sliver state, and passed through a roving machine and a spinning machine to be 9th (English cotton count).
Of the warp yarn and weft yarn, and a plain woven fabric having a warp density of 47 / inch and a weft density of 41 / inch was woven. Then, the water-soluble vinylon short fibers are dissolved and removed in warm water at 95 ° C for 30 minutes to remove 100% pineapple short fibers.
The product of Example 1 consisting of

Comparative Example 1 Using 40% by weight of pineapple short fibers similar to those of Example 1 and 60% by weight of water-soluble vinylon short fibers similar to those of Example 1,
The product was spun in the same manner as in Example 1, then a plain woven fabric was woven, and then the water-soluble vinylon short fibers were dissolved and removed to obtain a product of Comparative Example 1 consisting of 100% pineapple short fibers.
The obtained product was weak in strength and could not be put to practical use.

Comparative Example 2 Using 95% by weight of pineapple short fibers similar to those in Example 1 and 5% by weight of water-soluble vinylon short fibers similar to those in Example 1, spinning was carried out in the same manner as in Example 1 and then plain weave. Weaving
Then, the water-soluble vinylon short fibers were dissolved and removed to obtain a product of Comparative Example 2 consisting of 100% pineapple short fibers. The obtained product had many fluffs and could not be put to practical use.

[0019]

As described in detail above, according to the method of the present invention, a cloth made of pineapple fibers can be easily obtained, and the productivity can be improved. Further, the obtained cloth has no fluff on the surface, has a good appearance, and has a soft texture peculiar to pineapple fiber, which is very useful for casual use and the like.
