  Conventionally, a fabric using an elastic fiber covering yarn such as a polyurethane fiber is known as a stretchable fabric. However, these have a problem that drapability is not good.

  Furthermore, a stretchable woven fabric produced by using a polyester multifilament yarn of polyethylene terephthalate as a warp and / or weft without using a polyurethane fiber has also been proposed in Patent Document 1 below.

  However, since these woven fabrics use synthetic fibers and are filaments, they are long fibers. In the underwear, many people dislike the feeling of wearing, and many people prefer fabrics made of spun cotton (short fibers). .

  However, as a woven fabric using cotton spun yarn, for crimping or crimping, a strong twisted yarn of cotton spun yarn (a yarn that is further combusted from the spun yarn) is used as the weft, and the warp yarn is not subjected to additional combustion. Yarn (In order to distinguish this from the spun cotton spun yarn, it is abbreviated as cotton spun yarn or raw yarn in this application. Cotton spun yarn is usually subjected to Z-twisting to make spun yarn. Although there are also cotton-spun original yarns that have been spun and twisted with S twist.), They are stretchable in the weft direction of the fabric, but hardly stretchable in the warp direction.

Therefore, it is preferable that a cotton plain fabric that is stretchable in all directions can be provided even if cotton spun yarn that has not been supplemented is used, and the cost can be reduced.

  <3> In addition, as described in the above item (3), the warped yarn that has been twisted is subjected to a heat treatment and a pasting sizing treatment after the follow-up, and the twisted weft is subjected to a heat treatment after the follow-up, respectively. Once the twist is set, it is preferable because it can provide a raw fabric that can easily produce a cotton plain fabric having stretchability in all directions. It is preferable that the sizing treatment of the warp yarn is necessary because the warp yarn is moved up and down by a loom when weaving, and the weft yarn passes, so that the yarn can be prevented from breaking and breaking.

  <4> In addition, as described in the above item (4), the heat treatment is a heat setting with water vapor at 90 to 105 ° C., so that a cotton plain fabric having elasticity in all directions can be easily produced. This is preferable because it can provide an anti.

  <6> Further, as described in the above item (6), the raw fabric for producing a cotton flat fabric described in the above item (5) is laid out in a relaxed and dry manner after scouring including the removal of the glue. Cotton plain fabrics with stretchability are better used for cotton spun yarns for those who dislike wearing fabrics using synthetic fiber yarns, such as underwear, compared to fabrics using synthetic fiber filaments. A plain woven fabric having a feeling of wearing, a touch, a touch, and a water absorption property, and being stretchable in all directions in both length and width is preferable.

<7> Further, as described in the above item (7), a cotton spun yarn in which the twist direction of the raw yarn is Z-twisted as warp is 400 to 800 T / m (T in the same Z-twist direction as that of the raw yarn).

  <9> In addition, as described in the above item (9), the warp and weft heat treatment can be easily performed with a heat set with water vapor at 90 to 105 ° C., so that a cotton plain fabric having elasticity in all directions can be easily obtained.

  <10> Further, as described in the above item (10), when the gluing sizing treatment is a gluing sizing treatment at room temperature, the warp yarn is shrunk at this stage due to the treatment with the heated sizing agent. It is preferable that a part of the burned twist can be prevented from returning and, as a result, a cotton flat woven fabric that exhibits sufficient omnidirectional stretchability can be easily produced by scouring and relaxing drying.

  The raw fabric for producing a plain cotton fabric having elasticity in all directions according to the present invention is a cotton spun yarn in which the twist direction of the raw yarn is Z-twisted in the warp yarn and 400 to 800 T in the same Z-twist direction as that of the raw yarn. / M, preferably 500 to 700 T / m (T is the number of twists) warped yarn, and the weft yarn is a cotton spun yarn in which the twist direction of the original yarn is S twist is 800 to 1600 T / m in the S twist direction, preferably 1000 to 1400 T / m (T is the number of twists) Twisted strong twisted yarn and raw yarn spun cotton spun yarn with Z twist is 800 to 1600 T / m, preferably 1000 to 1400 T / m (T is The number of twists) is an original fabric formed in a plain weave structure using alternately twisted strong twisted yarns. If the number of additional warps of the warp and weft is the number of additional warps, if the number of additional warps is too large, the warp will be entangled with the adjacent warp when warping (setting the warp on the loom). It becomes easy to make normal fabrics difficult, and if the number of twists is too small, the stretchability in the machine direction is difficult to occur, and the stretchability in the all directions of the finally obtained cotton flat fabric tends to be difficult to realize. However, by setting the number of warp twists in the above range, a normal omni-directional stretchable plain fabric can be provided.

  In addition, by setting the number of wefts to be twisted within the above range, the weft yarn is less likely to be broken during the production of the raw fabric, and the resulting cotton flat woven fabric can also ensure the necessary lateral stretchability. In particular, it can be used as a raw material capable of providing an omnidirectional stretch flat cotton fabric.

  The thickness of the cotton spun yarn to be used is not particularly limited. However, from the viewpoint that a cotton fabric having a good texture and necessary strength, and finally an omnidirectional stretch flat cotton fabric can be obtained, 20 A count of 80 to 80 is preferred. The thickness of the cotton spun yarn used need not be uniform, and two or more types of spun yarns may be used as long as the object of the present invention can be achieved.

  In the present invention, “cotton spun yarn” and “cotton spun yarn” mean cotton and hemp blend spun yarn in which hemp blended with 50% by weight or less, more preferably 30% by weight or less.

At the time of forming the above-described raw fabric, a normal cotton-spun raw yarn to which no additional combustion is added may be used in combination with the warp. When using a normal cotton-spun yarn in combination, (A) one additional warped warp and one unsheathed cotton-spun yarn are used alternately as warps, or
(B) A sequence using the above-mentioned n additional warp yarns adjacent to each other and a sequence using the n cotton yarns not subjected to additional combustion adjacent to each other (where n is an integer of 2 to 10) are alternately used. Therefore, even if the cotton spun yarn that has not been combusted is used, the final omni-directional stretch cotton plain fabric tends to have a slight decrease in stretch, but the cost can be reduced. It is preferable because it can provide a texture that is different depending on the difference in stretchability, and an omnidirectional stretch flat cotton fabric.

  Further, in the raw fabric of the present invention, the twisted warp is set once by additional heat treatment and sizing treatment after additional combustion, and the additional twisted weft is once set by additional heat treatment after additional combustion. It is preferable that it becomes a raw fabric which can easily produce a cotton plain fabric having stretchability in all directions.

  For example, the heat setting is preferably performed for about 0 to 40 minutes by blowing water wound at 90 to 105 ° C. after putting the material wound on a bobbin or cheese into a heat treatment pot and reducing the pressure to a vacuum. However, in the case of warp, preferably after being heat-treated and wound on a bobbin or the like, it is heat-treated at a higher temperature in the above range and for a longer time in the above range, and then wound on the bobbin or the like. It is preferable to wind several yarns obtained by joining several taken yarns and winding them around the cheese, and to perform heat treatment twice at a lower temperature within the above range and a shorter time within the above range in the cheese winding state. . The weft is subjected to the heat treatment as described above in a state where the additionally combusted yarn is wound around the bobbin. The reason why the steam is blown into the heat treatment pot after reducing the pressure is to allow the steam to easily enter the wound bobbin and the yarn wound inside the cheese and to perform a substantially uniform heat treatment. is there.

  In addition, as described above, in the case of using a cotton spun yarn that is not supplemented to the warp as a raw fabric, the above-mentioned heat treatment is not necessary for the cotton spun yarn that is not supplemented, When warping is performed as necessary, the gluing sizing process may be performed or the gluing sizing process may be omitted, and when the gluing sizing process is performed, the glue is also used for the warp gluing sizing process of the twisted yarn. The type and concentration may be different. In that case, the container containing the sizing agent will pass through the sizing agent in a different container from the container containing the sizing agent of the warp warped.

  The sizing agent is not particularly limited, but typical examples thereof include poval and starch paste. Although the density | concentration of a paste is not specifically limited, The range whose paste component is 5 to 20 weight% in total with water is preferable.

  Thus, the raw fabric is formed by forming the twisted warp and weft thus formed in a plain weave structure.

  In order to obtain a cotton flat woven fabric having stretchability in all directions from the obtained raw fabric, the raw fabric is achieved by relaxing and drying after scouring including the above-mentioned glue removal.

  The scouring treatment including paste removal is not particularly limited, but a scouring agent using at least one kind of caustic soda, sodium carbonate, surfactant, etc. in heated water, preferably water heated to 80 to 90 ° C. Depending on the type of scouring, a scouring bath containing about 3 to 8% by weight, preferably a heated water bath containing caustic soda, although not particularly limited, for example, half-day to one-day scouring treatment.

  Thereafter, a cotton plain fabric having stretchability in all directions is obtained by relaxing drying. Relaxing drying means a drying method that does not apply tension, such as drying by applying tension, but does not apply tension. Specifically, tumbler drying or the like is preferable. The drying temperature is not particularly limited, but is preferably about 80 to 100 ° C. and about 20 to 30 minutes.

  The raw fabric is scoured after the paste removal, and then relaxed and dried, but it is not certain, but the additional combustion of warp and weft will be partially untwisted to become a cotton flat fabric that has elasticity in all directions It is estimated to be. In the above, the meaning of “partially untwisted by additional combustion” does not mean that the position of untwisting that is partially untwisted is part of the twisted number, Does not return to the original spinning yarn, but means that the twist added by additional combustion is untwisted as long as appropriate.

  The dyeing is optional, such as spinning yarn, that is, dyeing the raw yarn before additional combustion, dyeing after scouring, dyeing after relaxing drying (printing, printing, etc.).

  In the present invention, claim 3 (the item (3)) includes: “The raw fabric for producing a plain cotton fabric, the reheated warp is subjected to a heat treatment and a pasting sizing process after the reheating, and the weft is , The twist is set once by heat treatment after the additional combustion, and is formed into a plain weave. "It is an invention of the original fabric itself. Without treatment, as described above, it is necessary to prevent the yarn from breaking and breaking, and shows a state where glue is attached to the warp and the twist is set by heat setting. Investigating whether the paste has penetrated depends on the type, concentration and sizing time of the paste, and since the number of yarns is extremely large, it is not practical to take an average value. Is listed It has become a form.

  Claim 4 (said (4)) is an invention of a material that is also a raw fabric, but the manufacturing method states that "the heat treatment of the warp and weft is heat set by steam at 90 to 105 ° C". However, the physical measurement of the degree of heat setting varies depending on the degree of stress required for untwisting, and the average value must be taken. Since it varies depending on the situation, it is not practical, so the manufacturing method is described in spite of being an invention of the product.

  Claim 5 (claim (5)) is an invention of a material that is also a raw fabric, but the heating bath sizing treatment and how much warp shrinks or burns more than the sizing treatment at room temperature. Whether the twist partially returns depends on the number of additional burns, the thickness of the yarn, and the heat treatment temperature, and since it is not practical to measure, the manufacturing method is described. .

  Claim 6 (said (6) claim) is an invention of a cotton flat woven fabric having elasticity in all directions which is finally obtained in the same manner, but “the above claim 5 (said (5) claim)”. The raw fabric for producing a plain cotton fabric described in 1) is described as “a cotton plain fabric having stretchability in all directions, which is subjected to relaxation drying after scouring including the removal of the glue”.

  However, in practice, in order to obtain a cotton flat woven fabric having stretchability in all directions, the warped yarn subjected to additional heat treatment is subjected to heat treatment and paste sizing treatment after additional combustion, and the additional twisted weft yarn is applied after additional combustion. After the heat treatment, the twist is once set, formed into a plain weave, and after scouring including the glue removal, it is relaxed and dried to finally realize a cotton plain fabric having elasticity in all directions. . In the scouring process including the glue removal described above and the relaxation drying process, the warp and weft yarns are partially untwisted to produce a cotton plain fabric having stretchability in all directions. It is impossible to measure the untwisting ratio when trying to describe this in the form of a product. It is impractical (if the warp and weft are pulled out from the final fabric obtained, the number of twists after untwisting is measured. If you try to do so, the twist will return at the stage of pulling out, so the number of twists in the final fabric state is difficult to measure, and even if a means that can be measured is found, the number of warps and wefts is enormous. Therefore, it is impractical to obtain the average value.) Therefore, the cotton plain fabric having stretchability in all directions of the present invention is described as a manufacturing method. It is in shape.

However, the cotton-spun raw yarn not subjected to additional combustion is not heat-treated, and the sizing treatment is performed by sizing treatment with a normal temperature aqueous solution containing 25% by weight of poval, and the others are obtained in the same manner as in Example 1 to obtain a cotton plain fabric. It was. This cotton flat woven fabric was an omnidirectional elastic flat fabric, although its longitudinal stretchability was slightly smaller than that of Examples 1 and 2.
