Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a yarn suitable for a fabric such as a knitted fabric that has a surface change and gives a refreshing feeling, and a fabric that gives a tone using the yarn.
[0002]
[Prior art]
Conventionally, false twisted fused yarns having a feeling of unevenness due to tight parts and bulky parts are known, and a fabric made using this fused yarn is given a refreshing feeling due to the unevenness of the yarn structure. However, there is no feeling of jealousy.
[0003]
Japanese Patent No. 2533084 proposes to obtain a fabric having a tonal appearance using two or more kinds of yarns having a color difference. The yarn used here has a tight portion and a bulky shape. And both have a feeling of wrinkle with two different dyeing differences. Furthermore, the yarn proposed in Japanese Examined Patent Publication No. Sho 62-25771 has each single fiber constituting the yarn alternately thick and thin in the fiber axis direction, and has a random diameter change. The thick part has a high dyeing property, and is characterized in that the unevenness of the dyeing property and the unevenness of the alternating twist are not necessarily synchronized.
[0004]
[Problems to be solved by the invention]
As described above, in the related art, by providing a tight part and a bulky part to the yarn, it is possible to provide a fabric with a certain degree of coolness, but the surface feeling is still poor, and two or more types of fiber yarns are used. Even if it is used, a feeling of wrinkle appears randomly in both the tight part and the bulky part, and it is difficult to obtain a clear feeling of wrinkle (waltz feeling). Furthermore, even if the dyeing property is enhanced with the thick part of the single fiber, the unevenness of the dyeing property and the unevenness of the alternating twist do not synchronize, so the feeling of wrinkle exhibits a natural feeling of unevenness. ) Cannot be obtained.
[0005]
The object of the present invention is different from the false twisted yarn of the prior art, and when it is used to form a fabric such as a knitted fabric, a clear wrinkle feeling (waltz feeling) can be expressed on the surface of the fabric, and at the same time it is firmly wound. The twisted yarn portion (A) and the opposite twist, the twisted yarn-like portion (B) wound loosely, and the sense of unevenness due to the synergistic effect of the boundary portion (C) has a refreshing feeling rich in surface change The purpose is to provide yarn.
[0006]
Another object of the present invention is to provide a fabric with a refreshing feeling that exhibits a natural and clear uneven sensation and has a rough surface and a rich surface change.
[0007]
[Means for Solving the Problems]
The present invention is intended to achieve the above object, and in the yarn of the present invention, the single fibers constituting the yarn are thick and thin in the longitudinal direction of the fiber, and the thick portion is highly dyeable. And the yarn has alternately twisted yarn portions (A) tightly wound in the S or Z twist direction, and twisted yarn portions (B) wound around the loose having the twist in the opposite direction, and there boundary portion (C) is between the twisting portion (a) and the twisting-like portion (B), each of the boundary portion (C) is untwisted portion (C1), it was or, S Yo Li parts, are either reversing portion beauty Z twist section Oyo no twist section are mixed (C2),該撚thread portion (a) is rich in thick portions of the single fiber, also該撚filamentous portion (B) The boundary (C) is a refreshing material yarn that contains many details of the single fiber.
[0008]
In the present invention, as a preferred embodiment of the refreshing feeling material yarn, the twisted yarn portion (A) mainly exhibits a dark color by dyeing , and the twisted yarn-shaped portion (B) and the boundary portion (C) are mainly dyed. pale ~ exhibit dark, that the color portion is the dark color portion at 20-100% at a ratio from 0 to 80%, and the twisting portion (a) is present 10 to 150 per yarn 1m to, And it includes that the length of one piece is 50 mm or less.
[0009]
The invention according to claim 4 of the present invention is a fabric overflowing with a clear sense of tone composed of a refreshing feel yarn.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
As described above, the refreshing feeling material yarn of the present invention has a single fiber constituting the yarn that is thick and thin in the longitudinal direction of the fiber, and its thick portion is highly dyeable. The twisted yarn portion (A) tightly wound in the S or Z twist direction and the twisted yarn shape portion (B) wound around the loose having the twist in the opposite direction alternately, and the twisted yarn portion (A) and the twisted yarn shape boundary between the parts (B) is present (C), each of the boundary portion (C) is untwisted portion (C1), was or, S Yo Li unit, no twisting unit and are either reversing section Z twist section are mixed (C2),該撚thread portion (a) is rich in thick portions of the monofilaments and twisted yarn-like portion (B) and the boundary portion (C) of the single fibers A refreshing yarn with a lot of details.
[0011]
Thus, in the yarn of the present invention, the single yarn constituting the yarn has thick details, and the portion containing many thick portions has a lower melting point than the portion containing many details. The twisted yarn portion (A) is easy to wear and tightly wound, and this portion has a deep color because it contains many highly dyed portions.
[0012]
Meanwhile, the portion containing many details of the single fiber, in other words no thick portion is present is small or thick portion if the portion is poor in fusibility between the fibers, the untwisting as usual false twisting yarn Is done . Since the fused the end with not untwisted, in a portion including many details are correspondingly much untwisting, twine-like portion wound around loosely in twist in the opposite direction to the twisting part (A) (B) becomes When a portion containing a relatively high dyeing portion and a portion not containing it are present, a medium dark color and a light color are exhibited, and when a portion containing a high dyeing portion is not contained, a light color is exhibited.
[0013]
In the yarn of the present invention, the boundary portion (C) existing between the twisted yarn portion (A) and the twisted yarn-like portion (B) is present at the portion where the twist direction is reversed, and therefore is easily turned into a non-twisted portion (C1). Although some dyed portions remain, the length is not so long as to give a clear contrast to the fabric surface when it is made into a fabric. Also, if the boundary in the (C) is extremely short fusion distance, S Yo Li section with a short length, the inversion portion (C2) next to beauty Z twist section Oyo no twist section are mixed, similarly fabric surface It is not long enough to give a difference in shading.
[0014]
In the yarn of the present invention, the twisted yarn portion (A) has a shape including many thick portions of single fibers and tightly wound (twisted) in the S or Z twist direction as described above. In the present invention, the term “containing a large amount of single fiber” means a state in which a portion thicker than the average thickness of the single fiber of the twisted portion (A) is contained by 50% or more, preferably 60% or more. “Wound tightly in the twist direction” means that the twist number is preferably 35 to 85 times / inch, and a portion where the fibers are fused is included.
[0015]
The tightly wound twisted yarn portion (A) of the present invention is preferably present at 10 to 150, more preferably 30 to 100, per 1 m of the yarn, and the length is preferably 50 mm or less, more preferably 1 to 1 mm. 30 mm. When the number of twisted yarn portions (A) is small, when fabrics such as woven fabrics are used, the probability that dark colored portions will be adjacent to each other is reduced, so that the feeling of dullness is reduced and the effect is hardly exhibited. Moreover, when there are too many the number, the dark part will increase, and when it is made into a fabric, the unevenness | corrugation of the fabric surface will become large, and it will be transparent.
[0016]
In addition, in the yarn of the present invention, the twisted portion (B) includes a lot of details of the single fiber as described above, and has a form wound around a loose portion having a twist in the opposite direction to the twisted portion (A). ing. Here, including a lot of details of the single fiber means a state in which a portion thinner than the average thickness of the single fiber of the twisted portion (B) is contained by 50% or more, preferably 60% or more, in the opposite direction. The form wound around the loose having a twist means a state where the twist number is preferably 10 to 45 times / inch and there is no or little fusion part between the fibers.
[0017]
The twisted yarn-like portion (B) of the present invention is preferably present in an amount of 10 to 150, more preferably 30 to 100, per 1 m of the yarn, and the length is preferably 150 mm or less, more preferably 1 to 100 mm. . When the number of the twisted parts (B) decreases, the ratio of the tight parts increases, so that the unevenness on the surface of the fabric becomes large, and it feels transparent, and when the number of the twisted parts (B) increases, the bulky part The characteristic is emphasized and the tendency to become less refreshing is shown.
[0018]
Furthermore, in the present invention, a boundary portion existing between the twisted-like part and the twisting part (A) (B) (C ) , each of a number Dressings containing details of a single fiber, and the boundary portion (C) is untwisted portion (C1), was or, S Yo Li section, Ru der either an inverting portion beauty Z twist section Oyo no twist section are mixed (C2) with a short length. Here, the untwisted portion (C1) is a portion where there is substantially no twist. The reversing unit (C2) is a portion S twist section, the beauty Z twisting unit Oyo untwisted portion coexist. Here, the twisted portion is a portion where there is substantially no twist , and the S twisted portion and the Z twisted portion usually have a twist of about 1 to 10 times / inch.
[0019]
This boundary portion (C) of the present invention is preferably 10 to 200, more preferably 30 to 150, per 1 m of the yarn, and the length is preferably 10 mm or less, more preferably 0.1 to 5 mm. is there. The ratio of untwisted portion (C ₁₎ and the inverting section (C ₂₎ is, in the present invention 0: 100 to 100: is a 0, preferably 30:70 to 70:30.
[0020]
The yarn used in the present invention is a multifilament yarn made of a fiber-forming thermoplastic resin such as polyester or polyamide, and the single fiber constituting the yarn is thick in the longitudinal direction of the fiber like a chic and thin yarn type yarn. It is a filament yarn having fineness.
