Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a specially textured, strong-twisted container having a new texture, in which the single filaments are radially multiplied!! #If, a method for manufacturing a highly combustible i+x material using highly twisted yarns of a thermoplastic tIJI multi-fiber having an r-plane shape.

Traditionally, heat + iJ l"iQ multi-filament l has been used to produce highly twisted seaweed, georgette, chiffon, etc., which have a good crispy texture and have a textured surface (small irregularities). These products are manufactured in large quantities and are widely used in women's outerwear, such as pews, dresses, dresses, shirts, etc. However, in order to obtain ltQ products with good crispness, the core is pharyngeable. There are four requirements for multi-fittings to obtain heating at an angle of about 40° or more, and therefore the threads are expensive and strong (,
However, by adding moss to the filament, there were disadvantages such as a decrease in strength and an increase in bulkiness.

In order to improve these conventional drawbacks, the present inventors have
'iF, as a result of research, I arrived at it during the inter-weaving period, and its purpose is to reduce the cost of filaments that occur during high twisting, and to
)--Providing an ill, J manufacturing method for a special-texture strongly twisted fabric that can prevent a decrease in f and also produce a highly twisted fabric with a hemp-like crisp taste and bulkiness. The present invention is characterized in that the cross-sectional shape of the single filament is a special irregular cross section consisting of at least one type of radial 3 to 8'fJ, and at least 21 cm has a radial length of β. The ratio β/r to the radius r of the central core is 1.85 to 6.5, and the bar of the intermediate filament is 2.2 to 15.
The twist angle calculated using formula (1) for the 1.1 denier V1 multi-fiber is 25° to 38″.
It was obtained by heating it so that it becomes! i11? The gist of this paper is the history jf:', i method of a special texture strongly twisted fabric characterized by 1plI weaving using 41 yarns.

The thermoplastic multifilament used in the present invention is a filament having an irregular cross-sectional shape of h (3 to 8 radials) selected from the range of 3 to 8 radials, at least 1
This is a single filament.

Here, the thermoplastic material is 1/1/2 °C, and 9 examples are polyesters such as evaporated polyethylene terephthalate, polybutylene terephthalate, and polyethylene oxybenzoate, nylon 6, nylon 66, and nylon 6.10.
．． Nylon 6.12. Polyvinyl compounds such as polyvinyl alcohol, polyacrylonitrile, polyvinyl compounds such as nylon 11 and nylon 12, polyethylene, polypropylene, [which +I'lyolefin and rl&f
For example, a multifilament made of a polymer having a monofilament-forming ability, such as polyether, etc. can be mentioned.

In order to obtain a fabric with a unique hemp-like crisp texture in the present invention, the cross-sectional shape of the single filament must have leaves extending radially from the center and a function of 5 to 8 leaves. . For other cross-sectional shapes such as circular, rod-shaped, and 9 or more votes, Kaji-f, I! C, which is set, has only a few deformations and surface irregularities, so a sufficient effect cannot be expected. Single filament! As long as the number of 1liO is 3 to 8, the angle between the 9 lobes and the lobes does not necessarily have to be equal to 1', and they may have different filling lengths, with the center being medium-sized. Also good. Alternatively, a mixture of two or more types of single filaments having nine different numbers of leaves may be used.

The 11-screen shape of the single filament must be within the range of 1.85 to 6.5, where the ratio β/γ between the length β and the center radius γ is 1.85 to 6.5. .β/γ is 1
．． Below 85, the cross-sectional shape of the single filament is circular E.
If β/γ exceeds 6.5, a fabric with a unique +a-like crisp texture cannot be expected. llll! Stable and stable 1)
However, even if it were obtained, the texture of the fabric would be poor and the quality would be difficult to put into practical use. Particularly preferably, the desired range of β/1- is 6.0 to 6.0.

Next, in order to obtain a product that can be practically used as a KR product, in addition to the above-mentioned cross-sectional shape, the multifilament (41) of the single filament consisting of (19) also depends on the degree. ) synergistic with vdo)

There is a need to set it to 2 to 15 deniers. Preferably 7+

In the present invention, a core town 1 consisting of a tsubo thread filament having one shape as defined in 1,'j above and a degree of ~.I:
It heats the Mulder filament,
The angle at that time is calculated using formula (1) in fliJ4
The natural angle is between 25° and 38°. It is necessary to make it L. When heating the multifilament, the temperature is determined by the usual method.
), ゛C heat setting is performed at the same time as 79 or following heating. In the present invention, when the multifilament is heated, 11! between the single filaments! E and the bonds are well-shaped and interlock with each other, and the multifilament glue) protrudes from the circumference! , -・)() causes unevenness to be formed.

Therefore, fabrics using such threads have a natural and unique texture with a linen-like crispness. 1 ((If the angle is less than 25 degrees, the residual toxin/residue will be small) <'Cil'!! It is true that C also has grains (small irregularities): j'! <, and the crispiness is also become scarce.

On the other hand, when the combustion angle exceeds 38°, the 9 strength tends to decrease, and: f'll I:'t: becomes 1 and 9
Due to the purple color of the rlj yarn filament, unevenness is less likely to be formed on the outer periphery of the aged multifilament. In the present invention, the above-mentioned 1. One selection can be made as appropriate within each angle range.

The multifilament used in the present invention is as described above.
・Residual 1/l/l can be increased compared to multifilament made of f-lament.

For example, in order to obtain a fabric with the same degree of seaminess, it is necessary to add a multifilament made of 014 yarn filament with a 7-circular time plane to a multifilament with an angle of 46° or more. , wood) In the case of a single-light multifilament, 62 degrees (7 degrees is sufficient. 14. Therefore.

The twisting speed can be reduced by about 40%, and as a result, the twisting cost can be reduced by 3~'s W'l.

In the present invention, 1! ) is made into a woven fabric by ptp using the highly twisted yarn.
The strong fiber yarn of the present invention may be used for warp yarns and ζ/'1 yarns,
It may be used only for the warp or weft, or for a part of the warp or 11 threads. In order to effectively reflect the characteristics of the highly twisted yarn of the present invention in products, it is preferable to use the highly twisted yarn of the present invention in 50% or more of the entire fabric.

Below, nine aspects of the present invention will be explained based on the diagram F'll.

A void is formed between the single filaments entwined with τ, and +tti of the single filament protrudes from the outer periphery of the multifilament, forming unique unevenness.

The fabric thus obtained has a linen-like crispness because the interlayers of each hanging filament and one hole are intertwined with each other in a 4]1η manner, and the fabric has a linen-like crispness, and the interlayers between the single filaments are intertwined with each other. It exhibits bulkiness due to the presence of voids and irregularities on the outer periphery of the multifilament, and has a texture similar to that of natural + QilU due to the unevenness on the outer periphery of the multifilament.

The woven fabric reused and woven has less grain and less crispness, and on the other hand, 1. of No. 41q4-2. Fabrics using stain threads for the warp and weft threads have a similar texture, and the outer periphery of the threads has fewer irregularities, similar to threads with a circular cross section. It does not exhibit any unique texture.
