られている。2. Description of the Related Art Conventionally, crimped yarn crimped by a gear roller has been known, but generally, the crimped yarn has little change in crimped form, and a simple gear shaping is not suitable for commercialization. Since it lacks, various ideas such as changing the shaping pitch and mixing with other crimped forms have been used. Using this gear crimping process, the multifilament yarn is bundled and fixed to form a flat yarn.
It has been proposed and commercialized in Japanese Patent Publication No. 83335, etc., and it is possible to reduce the weight by increasing the specific volume of the flat yarn, and the glossiness due to the flattening and the sharpness due to the gear shaping part give a summer product. It is accepted as a clothing material.

Although it is possible to increase the gloss by heating at the heating temperature during gear crimp shaping, the yarn becomes coarse and hard, and uniform adhesion due to solvent application is difficult, resulting in uneven dyeing. The product value is reduced due to the occurrence of uneven texture and texture. Further, if a crimping process such as false twisting is also used, it is possible to impart a morphological change to the yarn, but an increase in cost due to the addition of a processing step is inevitable. An object of the present invention is to provide a flat crimped yarn having a glossy feel, a sharp feel, and a high elasticity.

In addition to interlacing, core yarn may be wound by coating and winding, or may be entangled by fluid entanglement with air or the like. When the entanglement treatment is performed by providing a speed difference in the supplied yarns during the entanglement, the high-melting fiber yarn 1 is fed more overfeed than the low-melting fiber yarn 2, and the obtained crimped yarn is stretched. It is preferable from the viewpoint of imparting the property. Regarding the yarn supply during the shaping treatment, in consideration of the shaping effect and workability such as yarn breakage and short fiber breakage, the yarn quality of the combined fiber yarn is taken into consideration in the range of -7% to + 12%.

十分である。The heater 7 is for heating the entangled and integrated yarn 5 for facilitating gear shaping performed in the next step, and any heating means can be used, but the heater 7 It is also possible to utilize the heater zone. The temperature of the hot plate of the heater 7 may be such that the low-melting fiber yarn 2 is fused by pressure during gear crimping immediately after the heater 7, and is near the melting point of the low-melting fiber yarn 2. It is enough.

たギアローラ８を用いて賦型するのが効果的である。The gear roller 8 is for imparting a micro crimp to the yarn 5 which is maintained in a heated state, and a gear roller having a module pitch of 0.1 to 0.5 mm is used. In this case, the gear roller 8 needs to be unheated. By pressing the yarn 5 using the pair of gear rollers 8 that are not heated, shear deformation is applied in a state in which the yarn 5 is not shaped smoothly, and the potential distortion of the applied crimp is caused. When it is alleviated with hot water or warm water, distortion is manifested, and the crimped yarn 11 is cracked or twisted, and the entire fabric can be made bulky and rich in variation.
From this point of view, the press shaping is performed by using the gear roller 8 in a shaping atmosphere at a temperature of 40 ° C. or lower by blowing a cooling air, or the gear roller 8 cooled to a temperature of 40 ° C. or lower. It is effective to shape with.

Due to the difference in heat shrinkage between the threads and the manifestation of potential strain during gear shaping, swelling or cracking occurs in the threads, and after the cloth is formed, the cloth as a whole can be in a shape that is rich in changes. . FIG. 3 shows the yarn form when the relaxation heat treatment is performed in the crimped yarn state.

It was fixed. When a dyeing process was performed after forming a fabric using this crimped yarn, the fabric was swelled or cracked due to the difference in heat shrinkage of the yarn, resulting in a rich surface change.

Furthermore, since it has a flat shape, the specific volume is large, and it is possible to form a lightweight cloth. Therefore, it is a material suitable for outdoor use such as summer clothing for women. Further, a fabric formed by using the crimped yarn is swelled or cracked due to a difference in thermal contraction of the yarn, due to a relaxation treatment with hot water or the like in the fabric treatment step,
It is possible to provide a fabric having a very rich surface change.
