Definitions
- the present invention relates to a composite processed yarn of a cellulose fiber and a synthetic fiber filament such as a polyester.
- a composite processed yarn of a cellulose fiber and a synthetic fiber filament such as a polyester.
- weft knitting it has no weft, has a high-grade appearance, has the gloss and texture of cellulose filament, and has shrink-proof and set-up properties.
- the present invention relates to a composite crimped yarn having excellent properties and a knitted fabric using the same.
- Cellulose filament is excellent in gloss, texture, hygroscopicity, drapability, and softness, making it an excellent material for clothing such as inners and outers.
- knitted fabrics tend to form weft steps, fail to provide a high-quality appearance, have poor dimensional stability and strength when wet, and tend to wrinkle, and have a low consumption.
- composite processed yarns combined with synthetic fiber filaments such as polyester have been proposed.
- Japanese Patent Application Laid-Open No. Sho 62-2999527 discloses that a polyester fiber and a regenerated cellulose fiber having a small boiling water shrinkage rate spun at a spinning speed of at least 700 OmZ min.
- a polyester fiber and a regenerated cellulose fiber having a small boiling water shrinkage rate spun at a spinning speed of at least 700 OmZ min.
- Japanese Patent Application Laid-Open No. Hei 8-1772038 discloses a self-crimp type, that is, a polyester filament and a regenerated cellulose filament made of a composite fiber in which two components having different shrinkages are bonded.
- a composite false twisted yarn has been proposed in which the knots are aligned or mixed fiber false twisted.
- this yarn is heated only during false twisting, and is not heated in the set zone after untwisting, the crimp becomes large. Polyester fiber easily emerges on the surface, making it difficult to obtain the gloss and texture of cellulose filaments, and the bulky and elastic texture unique to polyester with the unique polyester fiber. Poor quality.
- Japanese Patent Application Laid-Open No. 6-330042 discloses that a component having a specific side chain-type polyalkylene group, isophthalic acid, a polyalkylene glycol component, and the like are mixed at a specific ratio.
- cellulose fiber is fed so as to increase the amount of cellulose fiber in the sheath yarn, and a fluid pressure of 4 to 10 kg / cm 2 is used. A loop-shaped and force-shaped projection of the cell opening-and-filament is formed. For this reason, when knitted, the gloss and appearance of the cellulose filament are poor, and the polyester fiber in the core is not crimped. There is a drawback that it is dim.
- Japanese Patent Application Laid-Open No. 9-37440 discloses that a synthetic fiber filament having a boiling water shrinkage of 8% to 60% and a cell filament are mixed and false-twisted.
- the disclosed composite textured yarn is disclosed.
- 1 0 Since it does not pass through the heat set process after untwisting following the false twisting process at a temperature in the range of 0 to 250 ° C, the above synthetic fiber filaments are heated by dyeing or the like. Due to the appearance of crimps in the water treatment and the high degree of hot water shrinkage, the cellulose filaments are largely opened up, jump out of the composite processed yarn, and the yarn loop when knitted is disturbed. However, the appearance quality and texture are poor.
- Japanese Patent Application Laid-Open No. 5-163635 discloses a technique for suppressing the occurrence of the weft step by using a composite yarn in which a false twisted yarn of viscose rayon and a polyester yarn are fired.
- this composite yarn is twisted, the gloss and texture of the cellulosic filament cannot be obtained, and the polyester fiber is twisted so that the unique wind characteristic of polyester fiber is obtained. Go together.
- the occurrence of the weft step is not enough because the crimp is not applied to the polyester yarn.
- the texture has a certain texture, and in any case, a high-quality weft knit with a texture and texture that is as close as possible to 100% cellulose filament is not obtained. It is an object of the present invention to provide a composite material having a high quality appearance with no weft when formed into a weft knit, a gloss and feel of a cellulose filament, and further having excellent shrink-proof and set properties. An object of the present invention is to provide a crimped yarn and a weft knitted product using the same.
- the present inventors have completed the present invention as a result of intensive studies in view of the above-mentioned drawbacks.
- the present invention comprises 50 to 90% by weight of a cellulose filament and a synthetic fiber filament, and has a crimp elongation of 0.1 to 4.0%.
- FIG. 1 is a side view showing an embodiment of the composite crimped yarn of the present invention.
- FIG. 2 is a side view of a composite yarn as an example of a comparative example.
- the present inventors have found that the weft produced in a weft-knitted fabric containing a cellulose filament has a mechanical yarn distortion given by a knitting needle during knitting, friction between loops, and texture. It was discovered that distortion (variation in the shape and size of the loop between adjacent courses due to the adjustment limit of the knitting machine and the wear of the cam) was found.
- the inventors of the present invention have conducted intensive studies, and as a result, when minute clamps of cellulose filament are formed together with synthetic fibers, distortion of yarn and friction between loops are reduced. Suppression of the weft stage and the refining, heat setting, and dyeing finishing processes alleviate the distortion of the assembly, and the cell opening and swelling due to water swelling and drying.
- the crimp of the polyester filament disappears due to, for example, a heat set described later, and the cellulose filament is caused by a difference in shrinkage between the two filaments.
- the present inventors have found that the fiber constitutes the sheath portion of the yarn, and that the gloss and texture of the cellulose filament can be obtained, leading to the present invention.
- the composite crimped yarn of the present invention is one in which a cellulose filament having a fine crimp and a synthetic fiber filament having a fine crimp are mixed almost uniformly.
- the composite crimped yarn of the present invention is made of a synthetic fiber filler as shown in FIG.
- the core 2 has a core and the cellulose filament 1 has a sheath. This is considered to be because the synthetic fiber filament hardly newly generates crimp and exhibits a shrinkage property that does not disturb the cellulose filament. In this case, the cellulose filament mainly occupies the sheath without large arrangement disorder.
- the composite crimped yarn which is fired under normal false twisting conditions at a temperature 20 to 30 ° C lower than the melting start temperature of the synthetic fiber filament, is shown in Fig. 2.
- the synthetic fiber filament 2 has a large crimp, the arrangement of the cellulose filament 1 is greatly disturbed, and the synthetic fiber filament protrudes from the surface of the composite processed yarn.
- weft step refers to streak-like or striped color spots or thread pattern spots appearing along a specific yarn supply, different from the pattern expression by the knitting structure of the weft knitted fabric.
- the composite crimped yarn of the present invention is composed of a cellulose filament and a synthetic fiber filament, and has 50 to 90% by weight, preferably 60 to 90% by weight of a single cell filament. It is almost uniformly mixed at 80% by weight. If the cellulose filament ratio is less than 50% by weight, the gloss and texture of the cellulose filament cannot be obtained. On the other hand, if it exceeds 90% by weight, the wet strength is low, the dimensional stability is poor, and the weft is generated. The fact that the filaments are almost uniformly mixed means that the filaments are almost uniformly mixed over the entire cross section of the yarn, and even if the filaments are slightly uneven locally. I do not care.
- the ratio of the cellulose filament to the surface of the composite crimped yarn tends to increase due to the heat during false twisting.
- Such a phenomenon is preferable from the viewpoint of obtaining the gloss and texture of the cell opening and filament as the object of the present invention, and there is no problem even if such a phenomenon occurs. .
- fine crimp in the present invention means that the filament is fine. This refers to the state in which a small wave is formed, and the degree is defined by the crimp elongation ratio, which must be 0.1 to 4.0%, and preferably 0.2 to 3.0%. And more preferably 0.3 to 2.0%.
- the crimp elongation is less than 0.1%, the occurrence of the weft stage cannot be suppressed. If the content exceeds 4.0%, the crimp remains after dyeing, so that the ratio of the synthetic fibrous material appearing on the surface of the composite processed yarn increases, and the gloss and texture of the cellulose filament are impaired. .
- the crimp elongation rate is 0.1% to 4.0%, when the knitted fabric is used as a weft knit, the weft knit has a high-grade appearance with a reduced weft step, and the gloss of the cellulose filament. It has a good texture and excellent shrink resistance and set properties.
- a crimp elongation of 0.1 to 5.0% after boiling water treatment is preferable because the gloss and texture of the cellulosic filament can be easily obtained. Is 1.2 to 4.0%.
- the dry heat shrinkage of the composite crimped yarn of the present invention after the boiling water treatment is preferably from 1.0 to 5.0%. Under these conditions, when the knitted fabric passes through the heat setting step, the sheath-core structure having the cellulose fiber as the sheath and the synthetic fiber filament as the core is easily formed. If the dry heat shrinkage after the boiling water treatment is less than 1.0%, the formation of the sheath-core structure is insufficient, and if it exceeds 5.0%, the cellulose filament is disturbed, and It is not preferable because it is difficult to obtain the luster and texture peculiar to the filament.

Of these, the cellulose filament spun by the net process method is more easily entangled with the synthetic fiber filament by fluid entanglement, and a weft knitting occurs when it is formed into a weft knit. It is more preferable because it is difficult to do. Further, the cellulose filament used in the present invention may contain a matting agent such as titanium oxide and various known additives as necessary.

- polyester fibers of normal pressure dyeable type with a melting start temperature of 200 to 240 ° C are used, the texture is soft and the strength of the cellulose filament is deteriorated. Since even a small amount of aqueous alkali solution can be subjected to weight reduction processing, the texture of cellulose filament can be easily obtained.
- the Hoffman settability of the flat knitting is good, and the sewability and dimensional stability are good. Knitted fabrics, such as sheeting, which are liable to curl, are preferred because of their good time-setting properties.
