In the present invention, first, a core-sheath structured spun yarn in which a water-soluble fiber is provided in a core portion and a short fiber group containing at least a binder fiber is provided in a sheath portion is manufactured. The water-soluble fiber of the core is a fiber that dissolves at least in boiling water, and a polyvinyl alcohol fiber that maintains water solubility by adjusting the degree of saponification is preferably used, and is a fiber that dissolves in warm water at 60 to 70 ° C. Is preferred. This water-soluble fiber is a long fiber yarn,
Short fibers may be used. The sheath portion of the spun yarn may be composed of only the binder fiber, but is usually composed of a short fiber group in which the binder fiber and other fibers for spinning are mixed. The fiber for spinning used by blending with the binder fiber is a fiber having a melting point higher than the binder component of the binder fiber or a fiber having no melting point, and is a fiber for normal spinning such as cotton and hemp. Fibers, animal fibers such as wool and silk, recycled fibers such as rayon and acetate, and synthetic fibers such as polyester, nylon, acryl, and vinylon.

として通常上記のような複合繊維を用いる。[0006] The binder fiber is a fiber having as a binder component a polymer having a melting point lower than the melting point or decomposition point of other fibers constituting the sheath portion. This binder fiber is a single-component fiber consisting of only a binder component, and is a composite such as a core-sheath type, a side-by-side type, a sea-island type, and a split fiber type in which the binder component forms all or a part of the surface of the fiber. It may be a fiber. When the sheath portion of the spun yarn is composed of only the binder fiber, the above-described conjugate fiber is usually used as the binder fiber.

で好都合である。The binder component of the binder fiber may be a polymer having a melting point lower than the melting point or the decomposition point of the fiber constituting the sheath as described above.
It is preferably from 0 to 200 ° C. If the melting point is less than 100 ° C., the resin is melted by the heat which can be normally applied during the dyeing process, and it becomes difficult to control the melting point. If it exceeds 200 ° C., it is difficult to melt in the heat setting step at the time of finish processing, and it is difficult to obtain a fusion effect by the binder fiber. Examples of the polymer that can be used as the binder component include polyethylene, polypropylene, copolymer nylon, copolymer polyester, and the like. Examples of the copolyester include those obtained by copolymerizing polyethylene terephthalate with two or more compounds selected from isophthalic acid, sebacic acid, adipic acid, diethylene glycol, 1,4-butanediol, and the like. , Ethylene terephthalate unit and / or butylene terephthalate unit
It is convenient to use a polyester obtained by copolymerizing a caprolactone unit and having a melting point of 130 ° C. or more, since the heat-fused fibers do not dissolve during dyeing even at 130 ° C.

For example, according to the method described in Japanese Patent Publication No. 56-11775, a roving sliver composed of a water-soluble fiber and a sliver composed of a short fiber group containing a binder fiber for a sheath portion is roving-formed. To produce a roving having a core-sheath structure in which the water-soluble fiber is disposed in the core, and then spinning with a spinning machine. When the water-soluble fiber is a long-fiber yarn, a roving composed of a group of short fibers containing binder fibers for a sheath portion is drafted in a predetermined draft zone by a spinning machine and then water-soluble by a front roll. It can be obtained by overlapping with a long fiber yarn of a conductive fiber and twisting by a ring method.

If the ratio of the core part is small, the lightweight effect due to the hollow will not be sufficient,
If the ratio of the core exceeds 50%, the hollow may be crushed by an external force. If the ratio of the binder fiber in the core is less than 20%, the number of bonding points between the constituent fibers decreases, and the hollow may be crushed by an external force.
