Description

The present invention relates to composite twisted yarns.

Cotton fiber is highly hygroscopic, heat-retaining, and resistant to washing, so it is widely used for underwear, terry cloth, sheet cloth, etc., which come in direct contact with the skin. According to known literature, the twist coefficient for each type of cotton yarn (twist coefficient is a constant that indicates the relationship between the thickness and the number of twists of the yarn, and the twist coefficient = number of twists per inch of yarn ÷ British cotton count The square root of ) is 2.5 to 3.5 for normal knitted yarn, 3.25 for soft twisted weft, 3.25 for normal weft, and 3 for soft twisted warp, with a minimum range of 2 or less for high-grade knitted yarn. 0.75, normal warp 4.0, normal hard-twisted yarn 4.5, raw yarn for Chirimen 5 or more, and so on. Moreover, in woven or knitted fabrics using spun yarns, composite yarns in which spun yarns and polyurethane elastic yarns are combined are widely used in order to impart stretchability to the woven or knitted fabrics. Typical examples include core spun yarn in which a core yarn made of polyurethane elastic yarn is covered with cotton for spinning and twisted, and a single layer or multiple layers of spun yarn around a core yarn made of polyurethane elastic yarn. There are single covered yarns and double covered yarns that are wound around the fabric, and ply yarns that are obtained by twisting two or more spun yarns and polyurethane elastic yarns, and it is common to use these composite yarns to produce elastic woven and knitted fabrics. ing.

For example, in Patent Document 1, a two-ply yarn made of 100% cotton fiber, a thick yarn with a twist coefficient of 3.0 to 4.0 and a fine yarn with a twist coefficient of 3.0 to 4.0 are aligned, A two-ply yarn twisted in the direction opposite to the single yarn twist direction and having a twist coefficient of the two-ply yarn of 2.0 to 3.5 is disclosed. It is introduced that a terry cloth having a comfortable texture, waist and elasticity can be obtained.

However, in Patent Document 1, the single yarns of different counts are twisted in the opposite direction of the twisting direction to make a very soft twisted yarn, so that a good texture can be provided, but the elasticity and bulkiness are increased due to the stiffness and stiffness. However, it was difficult to produce a woven or knitted fabric with excellent air permeability.

SUMMARY OF THE INVENTION In view of the above problems, the present invention aims to provide a composite twisted yarn which, when woven or knitted, has high stretchability, good texture, and excellent bulkiness and breathability. and

As a result of intensive studies to solve the above problems, the inventors of the present invention obtained by twisting spun yarns of different yarn counts in the same twisting direction in a twisting direction opposite to the twisting direction of the spun yarns. When a woven or knitted fabric is made from the composite twisted yarn and subjected to a conventionally known post-treatment, the woven or knitted fabric is imparted with high stretchability, and the woven or knitted fabric is plump and has a good texture, and has properties such as breathability. The present invention was completed by discovering that it is excellent in

That is, the present invention provides the following preferred aspects.
[1] A composite twisted yarn composed of a spun yarn A with a thick count and a spun yarn B with a fine count and satisfying all of the following conditions.
1) the spun yarn A and the spun yarn B have the same twist direction;
2) The twist direction of the composite twisted yarn is twisted in the direction opposite to the twist direction of the spun yarn A and the spun yarn B;
3) The number of twists of the composite twisted yarn is 1.0 to 2.0 times the number of twists of the spun yarn A.
[2] The composite twisted yarn according to [1], wherein the number of twists of the composite twisted yarn is 1.0 times or less the number of twists of the spun yarn B.
[3] The composite twisted yarn according to [1] or [2], wherein the spun yarn A and the spun yarn B are spun yarns made of cotton.
[4] The above [1] to [3], wherein the yarn count ratio of the spun yarn A and the spun yarn B (the yarn count of the spun yarn B/the yarn count of the spun yarn A) is 3 to 20. The composite twisted yarn according to any one of the above.
[5] The composite twisted yarn according to any one of [1] to [4], wherein the spun yarn A has a count of 6 to 20 and the spun yarn B has a count of 60 to 120.
[6] A woven or knitted fabric at least partially using the composite twisted yarn according to any one of [1] to [5].

Since the composite twisted yarn of the present invention is twisted in a twisting direction opposite to the twisting direction of the spun yarn, when it is made into a woven or knitted fabric, it has high stretchability and bulkiness, and has good texture and breathability. An excellent composite twisted yarn can be provided.

Furthermore, since the composite twisted yarn used in the present invention has a fine count, it has less fluff and also serves as a reinforcement, so troubles such as yarn breakage occur even when using high-speed looms and knitting machines. The woven or knitted fabric can be smoothly produced with high productivity without performing sizing treatment at the time of warping.

The present invention will be described in detail below.
The spun yarn constituting the composite twisted yarn of the present invention is composed of a thick spun yarn A and a finer spun yarn B, and the spun yarn A and the spun yarn B are twisted in the same direction (for example, both directions). Both yarns are S-twisted or Z-twisted). The spun yarn A and the spun yarn B are set in a twisting machine, and the direction opposite to the twisting direction of the spun yarn A and the spun yarn B (for example, when the spun yarn A and the spun yarn B are S twist, Z twist, spun yarn A and S twist if the spun yarn B is Z-twisted), so that the spun yarn A and the spun yarn B constituting the composite twisted yarn are untwisted simultaneously in the same direction.

Here, the "twist number of the spun yarn" as used in the present invention means the number of twists applied at the end of manufacturing the spun yarn. For example, if the spun yarn is a single yarn, it refers to the number of twists applied during spinning to produce a single yarn. It refers to the number of twists, and in the case of a plied yarn of 3 or more, it means the number of twists when 3 or more yarns are twisted together to produce the plied yarn.

The number of twists of spun yarn A and spun yarn B is not particularly limited. A spun yarn having a twist coefficient K of 2.0 to 6.0 is preferably used from the viewpoints of quality stability of spun yarn, productivity in manufacturing composite twisted yarn, easy availability of spun yarn, and the like. The twist coefficient K of the spun yarn A and the spun yarn B is more preferably 2.5 to 5.5, still more preferably 3.0 to 5.0.

In the composite twisted yarn of the present invention, the twisting direction of the composite twisted yarn must be opposite to the twisting direction of the spun yarn A and the spun yarn B constituting the composite twisted yarn. By reversing the twisting direction of the composite twisted yarn and the twisting direction of the spun yarn A and the spun yarn B, the torque of the composite twisted yarn can be reduced and the texture can be improved. In addition, the plying for producing the composite twisted yarn works in the direction of untwisting the twists of the spun yarn A and the spun yarn B, and this untwisting causes the yarn length of the spun yarn A of thick count to be the spun yarn B of fine count. Twisting is performed in a state where the spun yarn A with the longer yarn length covers the spun yarn B, and the thick spun yarn A covers the fine spun yarn B better. done.

In the composite twisted yarn of the present invention, it is important that the twist number of the composite twisted yarn is 1.0 to 2.0 times the twist number of the spun yarn A of the thick count.
If it is less than the above lower limit, the stability of twisting of the composite twisted yarn becomes poor, and the weaving and knitting properties of the composite twisted yarn tend to be inferior due to the strength variation of the composite twisted yarn, insufficient fluff suppression, and the like. During the pliing and twisting process, untwisting of the spun yarn tends to be insufficient. On the other hand, when the above upper limit is exceeded, troubles such as yarn breakage occur when twisting to produce a composite twisted yarn, resulting in a decrease in productivity of the composite twisted yarn, a decrease in the strength of the obtained composite twisted yarn, and a decrease in the strength of the obtained composite twisted yarn. It is easy to cause process defects during weaving and knitting using. In addition, since the torque of the composite twisted yarn due to twisting becomes too strong, process defects when applying twisting to manufacture the composite twisted yarn, and process defects during weaving and knitting tend to cause a decrease in productivity. . The number of twists of the composite twisted yarn is preferably 1.1 to 1.8 times, more preferably 1.2 to 1.6 times that of the spun yarn A.

That is, in the present invention, the number of twists of the composite twisted yarn is 1.0 to 2.0 times the number of twists of the spun yarn A at the time of plying for manufacturing the composite twisted yarn, so that the morphological stability of the composite twisted yarn ( While maintaining the stability of the twist), the plying twist for producing the composite twisted yarn works in the direction of untwisting the twists of the spun yarn A and the spun yarn B, and during the plying, one of the spun yarns is untwisted. In addition, the other spun yarn undergoing twisting with the same untwisting number changes from normal twist to soft twist yarn, becomes a reinforcing yarn of the twisted composite twist yarn, and is further untwisted or in a state similar to this. The threads are twisted in a state in which gaps are generated by being close to each other. As a result, weaving and knitting can be performed satisfactorily when producing a woven or knitted fabric from the composite twisted yarn, and the woven or knitted fabric obtained thereby has increased stretchability, bulkiness, and a good texture, A woven or knitted fabric having excellent air permeability can be obtained.
The "twist number of the composite twisted yarn" as used in the present invention means the number of twists when the spun yarn A and the spun yarn B are twisted together. becomes.

Regarding the number of twists of the spun yarn B of fine count, in the composite twisted yarn of the present invention, the twist number of the composite twisted yarn is preferably 1.0 times or less that of the spun yarn B of fine count. The number of twists of the fine spun yarn B varies depending on the number of counts and twists of the fine spun yarn B before pliing and twisting, and the number of twists applied when manufacturing a composite twisted yarn (at the time of pliing). However, if the number of twists of the composite twisted yarn relative to the number of twists of the spun yarn B exceeds the above upper limit, the strength of the fine-count spun yarn is greatly reduced, and the yarn may not function sufficiently as a reinforcing yarn. The number of twists of the composite twisted yarn with respect to the number of twists of the spun yarn B is more preferably 0.8 times or less, particularly preferably 0.6 times or less.

The conjugate twisted yarn of the present invention is determined by the balance of three factors: the twist of the spun yarn A with a thick count, the twist of the spun yarn B with a fine count, and the untwisting number after conjugate twisting. The twist number of the spun yarn A must be in the range of 1.0 to 2.0 times. It is possible to obtain a woven or knitted fabric which has high stretchability, which is the object of the present invention, and which is excellent in appearance, feel, breathability and lightness.

The spun yarn A and the spun yarn B of the present invention may each be a single yarn, two-ply yarn, or a plied yarn of three or more yarns. As the material, it is preferable to use cotton, rayon, viscose, linen, polyester, acrylic, or the like. In particular, when it is used for woven or knitted fabrics, it is preferable to use spun yarns made of cotton because they are excellent in touch, softness, and airiness when used.

Regarding the composite twisted yarn used in the present invention, from the viewpoint of twisting processability, weaving and knitting properties, appearance, and texture, the difference in yarn count between the spun yarn A with a thick count and the spun yarn B with a fine count, that is, the count of the spun yarn B /Spun yarn A count ratio is preferably 3-20. The count ratio of the spun yarn B/the count of the spun yarn A is more preferably 4-15, more preferably 5-10. More specifically, the spun yarn A preferably has a count of 6 to 20, more preferably 8 to 12. If the spun yarn A of thick count is less than the above lower limit, the torque of the spun yarn B of fine count remains, and good texture may not be obtained. If the spun yarn A with a thick count exceeds the above upper limit, the difference in yarn count from the spun yarn B with a fine count becomes small, the gap between the single yarns becomes small, and the bulkiness and texture may deteriorate. The spun yarn B preferably has a count of 60 to 120, more preferably 80 to 100. If the fine count spun yarn B is less than the above lower limit, it may not become a supporting yarn for the thick count spun yarn A, causing problems such as omission. If the fine count spun yarn B exceeds the above upper limit. , the remaining torque may make it difficult to cover the spun yarn B with a fine count with the spun yarn A with a large count.

The type of yarn twisting machine for twisting the thick spun yarn A and the fine yarn B is not particularly limited. can.

The composite twisted yarn obtained as described above generally has torque. If the torque does not interfere with the weaving/knitting process, it can be used as it is for the production of the woven or knitted fabric without reducing the torque. If the torque interferes with the weaving/knitting process, it is preferable to reduce the torque by heat treatment.

The composite twisted yarn of the present invention can also be suitably used for woven or knitted fabrics. As the knitted fabric, any knitted fabric such as weft knitting (knit), tricot warp knitting, and raschel warp knitting may be used. The woven fabrics include basic textures such as plain weave, twill weave, and satin weave, and modified textures derived from them (e.g., crepe weave, crepe weave, etc.), honeycomb weave, single double weave, double weave, and the like. A layered structure, a pile structure such as a coal layer, and a velvet pile structure.

Woven or knitted fabrics made from composite twisted yarns that satisfy the above requirements have high stretchability, a good feeling of swelling, and excellent breathability. Pants, sportswear, underwear, foundation, other clothing, medical applications such as elastic bandages, vehicle interior materials, fabrics for belt conveyors, food uniforms, medical uniforms, surgical gowns, hospital gowns, lab coats, work uniforms, aprons , hats, gloves, and other clothing; futons, futon covers, pillow covers, beds, bedspreads, sheets, bath mats, towels, face towels, body towels, cabinet towels, tablecloths, slippers, and other daily necessities; table cloths and mops Cleaning supplies such as threads and rolling wipers; curtains, shower curtains, nets, doorknob covers, carpets, food containers, and other living materials; filter materials for air conditioner filters, air purifiers, and water filters; It can be effectively used in a wide range of fields such as industrial materials such as boards and wallpapers. In particular, it is suitably used for clothing such as denim, shirts, pants and underwear due to its high stretchability, bulkiness, texture and breathability.
