高性、保温性等を十分に満足するものではなかった。However, in the case where bulkiness is imparted by using a spun yarn in which fibers having different shrinkage ratios are mixed, the fabric itself shrinks and the woven or knitting structure becomes dense and hardened. Occurs. There is also known a method of weaving / knitting in advance so that the weaving structure has a low density in anticipation of shrinkage. And is hardened as a result. When a bulky spun yarn is used, the running resistance of the bulky spun yarn is increased in the weaving / knitting process, the weft driving speed is reduced, and the spun yarn is efficiently used for the knitting needle hemus during knitting. There is a problem that is difficult to supply to. On the other hand, a spun yarn using hollow fibers for maintaining bulkiness while ensuring productivity and flexibility is also disclosed in Japanese Patent Application Laid-Open No. 7-58200.
However, it has not been sufficiently satisfied with respect to flexibility, bulkiness, heat retention and the like.

ものである。The hollow twisted yarn referred to in the present invention is a twisted yarn in which fibers are substantially absent in the central portion, and specifically, FIG.
Something like. The hollow rate is preferably 25 to 80%, particularly preferably 30 to 70%. In general spun yarn, the porosity is at most about 20%. If the hollow ratio is too small, the effects such as bulkiness and heat retention may be insufficient, and if it is too large, the shape stability of the hollow portion may be insufficient. The term "hollowness of twisted yarn" as used in the present invention refers to the cross-sectional area of the fiber portion and hollow portion of the twisted yarn cross section as S1, and the cross-sectional area of hollow portions between single fibers (excluding hollow portions formed in single fibers). Is S2, it means a value (%) represented by the formula S2 / S1 × 100. Therefore, it is clearly distinguished from the hollow ratio of hollow fibers (the area ratio of the hollow portion in the cross section of the single fiber).

とができる。The hollow twisted yarn of the present invention can be produced by removing the core component of a core-sheath type composite yarn, that is, a composite spun yarn / structured yarn having a core-sheath structure. It may have a multi-core structure, but a single-core structure is more preferable. Such a core-sheath type composite yarn can be manufactured by an ordinary method. For example, the core-sheath component is separately supplied and passed through the blended cotton process and the carding process, and the core component is arranged in the center and the sheath component is arranged on both sides of the core component so that the predetermined core-sheath ratio is obtained, and then the product is drafted. It can be obtained by spinning the obtained sliver as it is and spinning.
Also, the core-sheath component is separately supplied to form a sliver, and after setting the spinning amount according to the desired core-sheath ratio, the core component is placed in the center and the sheath component is placed around it. (Or by supplying one roving yarn of the core component and one roving yarn of the sheath component one by one), and spinning is also possible. When spinning is carried out, spun yarn of the core component may be supplied from the front roller. Even if the core component is a filament, it can be spun similarly.

い。From the viewpoint of maintaining a hollow state, that is, in terms of morphological stability, it is preferable to mix a small amount of fibers that are hardly dissolved during the core component removing treatment as the core component.
It is preferably composed of fibers which are not easily dissolved by about 20% by weight. As the mixed fiber, for example, fibers such as polyester fiber, polyacrylic fiber, rayon fiber, cotton, wool, and silk can be appropriately selected, and the performance is deteriorated or a large shrinkage occurs during the core component removal treatment. It is preferable to select one that does not cause When the hollow twisted yarn is used for clothing, the fibers to be mixed are preferably ultrafine fibers of about 0.1 to 1 d. When hollow fibers are used as the fibers to be mixed with the core component, it is possible to manufacture a fabric having high morphological stability, light weight, and excellent heat retention. Further, when a multifilament such as polyester is arranged, the tensile strength stress of the fiber can be remarkably increased. When the filament is used as the core component, it is preferable to supply the filament to the center of the fleece and apply spinning to the filament while applying tension to the filament.

Those which can be suitably used, and of course, such fibers may be mixed with fibers such as cotton and hemp. Further, a fiber having a shape memory ability, a hollow fiber, and a modified cross-section fiber such as a flat or triangular shape may be used. Particularly, when the hollow fiber is used, a more excellent effect can be obtained. The heat treatment is preferably performed with a fixed length. further,

加剤を含んでいても良い。The sheath component may be composed of multifilaments. For example, a composite twisted yarn can be produced by the same method as spinning a core-sheath type composite yarn except that the filament is supplied to the outside of the fleece, and a hollow twisted yarn can be obtained by removing the core component. it can. In particular, when the sheath component is supplied at a rate of 1 to 5% faster than the spinning speed of the core component fleece, the coverage of the sheath component is increased and the morphological stability of the hollow portion when formed into a hollow twisted yarn is improved. Therefore, it is preferable.
It is also possible to employ a method in which only the core component is supplied to an ordinary spinning machine, and a multifilament is supplied and wound in a winding portion while drafting and twisting, or a method in which the multifilament is wound around a spun yarn. When the sheath component is composed of multifilaments, the fluff is small and the texture is excellent, but the morphological stability of the hollow part when the hollow twisted yarn is formed may be insufficient, so the core component It is preferable to mix fibers other than the soluble fiber with the above. Inorganic substances such as titanium oxide, kaolin, silica and barium oxide, carbon black, colorants such as dyes and pigments, antioxidants, ultraviolet absorbers and light stabilizers are added to the fibers constituting the sheath component. You may include the agent.

５％未満であるのが好ましい。By using such a hollow twisted yarn, it is possible to produce a lightweight and bulky fabric which is excellent in flexibility and heat retention, but the hollow twisted yarn itself may be stretched by tensile stress and the hollow portion may disappear. Therefore, it is preferable to remove the core component after manufacturing the fabric. In particular, from the viewpoint of morphological stability, it is preferable to manufacture the cloth using the hollow twisted yarn and the solid yarn. The solid yarn referred to in the present invention is a yarn in which a hollow portion (excluding the hollow portion formed between single fibers) does not substantially exist in the central portion of the yarn, and the hollow ratio is less than 20%, particularly 1%.
It is preferably less than 5%.

繊維を適宜選択して使用すればよい。Although it is possible to form the fabric with only the hollow twisted yarns, it is preferable to mix solid yarns when the hollow twisted yarns are highly required to retain the hollow portion. From the viewpoint of the morphological stability of the hollow part, it is preferable that the load applied to the fabric is borne by the solid yarn only (increase the mixing ratio of the solid yarn), but if the ratio of the solid yarn is too high, the fabric becomes bulky. However, the soft feeling and the like will be impaired. Therefore, the ratio of the number of hollow twisted yarns and the number of solid yarns is 100: 0 to 20:80,
In particular, it is preferably 40:60 to 60:40. The driving ratio may be appropriately set depending on the purpose. As the solid yarn, yarns of any form such as spun yarn and filaments can be used, and can be made of hollow fibers or modified cross-section fibers as in the case of hollow twisted yarns. The type of fiber used is not particularly limited, and synthetic fibers such as polyester fibers and polyamide fibers, and natural fibers such as cotton and hemp may be appropriately selected and used.

挙げられる。The form of the cloth is not particularly limited and may be appropriately selected depending on the purpose and use such as woven fabric and knitted fabric, but from the viewpoint of morphological stability, woven fabric such as plain woven fabric is preferable. Generally, a woven fabric has extremely low stretchability, but a woven fabric using the hollow twisted yarn of the present invention has a high stretchability, and an excellent effect can be obtained especially for clothing. The elasticity can be adjusted by the driving ratio of the solid thread, because the elasticity decreases when the solid thread is mixed. An excellent fabric can be obtained by performing core component removal treatment such as hot water treatment, alkali dissolution treatment, and solvent treatment after forming the fabric. Of course, the fabric may be manufactured after forming the hollow twisted yarn. The fabric using the hollow twisted yarn of the present invention is excellent in lightness, heat retention, hygroscopicity, stretchability, etc., and thus can be used for all purposes. For example, inner and outer garments for clothing, large decorative curtains and heat-shielding curtains for living applications, and tents, canvas, waterproof cloths for industrial use, and the like.
