DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a combined and multi-component false-twist textured filament yarn constituted by at least two kinds of multi-filament yarns having different sectional shapes and having a slippery and pliable(sara-sara) feeling, a production method of such a yarn, and a knitted/woven fabric having water absorption property.
More particularly, the present invention relates to a combined and multi-component false-twist textured filament yarn suitable for a woven fabric having a slippery and pliable(sara-sara) feeling different from a harsh and stiff(shari) feeling obtained conventionally by hard twist, and a drape property, to a production method of the yarn, and to a knitted/woven fabric having an excellent drape property and a high water absorption property and equipped with slippery and pliable(sara-sara) touch which restricts a wet and gooey(betotsuki) feeling under a water retention state.
BACKGROUND ART
Conventionally, polyester multi-filament yarns have been used unlike other synthetic fibers such as nylon or acryl because the polyester multi-filament yarns can impart excellent drape property to a woven fabric and can express en elegant silhouette particularly in female dresses.
To impart the drape property, hard twist must be applied to the polyester multi-filament yarn. The yarn is then woven, and the resulting grey goods is subjected to alkali weight loss in a dyeing process and a woven fabric is obtained.
The application of hard twist not only imparts the drape property to a woven fabric but also provides the effects of eliminating a conventional waxy feeling of the woven fabric and imparting a dry and harsh and stiff(shari) feeling. This harsh and stiff(shari) feeling is different depending on the number of hard twists and when the number of twists is excessively great, feeling becomes hard and the woven fabric comes to have an undesirable hard and sandy(jyari) feeling.
When hard twist is applied to the conventional multi-filament yarn so as to impart the drape property or the harsh and stiff feeling, the multi-filament yarns are highly bundled, and the resulting woven fabric comes to have a hard feeling not having a puff property and soft feeling due to the twist structure. To solve this problem, Japanese Patent Publication Nos. 19733/1986, 31210/1986 and 61422/1988 propose a multi-component structure false-twist textured yarn having a core-sheath two-layered structure by compositing at least two kinds of multi-filament yarns having different elongations and drawing and false twisting them.
This structure of the composite structure false twisted finished yarn forms a two-layered structural form having a difference of yarn lengths between core yarns and sheath yarns. In the additional twist process, therefore, a twist yarn tension is first applied to the core yarn side having a smaller yarn length and twist is imparted under a bundled state. As the number of twists further increases, twist is gradually imparted to the group of multi-filaments on the sheath side, and the yarns are twisted around the core yarns. Accordingly, even when the number of twists increases, the multi-filament yarns on the sheath side can form gaps and tend to possess a puff property and a soft feeling.
On the contrary, because the drape property is not sufficient, the woven fabric is not satisfactory. To obtain the drape property or the dry feeling, the number of hard twists must be further increased, so that the drop of the puff property and the soft feeling due to the increase of the number of twists is invited. This problem is remarkable particularly in medium thick woven fabrics using the finished yarns.
As described above, when twisting is effected in the conventional polyester multi-filament yarn or the multi-component structure false-twist textured yarn having the core-sheath two-layered structure so as to obtain the drape property and the dry and harsh and stiff(shari) feeling, the puff property and the soft feeling drop, and when the puff property and the soft feeling are sought, the d
