Description

TECHNICAL FIELD The present invention relates to a stretchable knitted fabric, and more particularly to a stretchable knitted fabric suitable for clothes such as swimwear and leotards that require a body shape adjusting effect.

(Prior art) Circular knitted fabric using nylon false twisted yarn has been known for a long time as a knitted fabric for swimwear, leotards, etc., but recently, stretch yarns such as spandex and long fibers such as nylon and ester have been interwoven. The warp knitted fabric or the circular knitted fabric obtained by interlacing the above-mentioned spandex yarn or its composite yarn (covered yarn, core yarn) and spun yarn is excellent in elasticity, and has a good fit feeling.
It is often used because it is comfortable to wear. Since these knitted fabrics have large stretchability, they are often knitted using a single spantex yarn having a relatively small stretch force. Therefore, when wearing a swimsuit, leotard, etc. made only from these knitted fabrics, it fits closely to the body and has good fit properties, but the elastic force is small, so the abdomen, buttocks, etc. of women in particular tend to protrude, and the body shape correction effect Little In order to remedy these drawbacks, a thin stretchable yarn portion in a garment such as a leotard or a swimsuit, which is formed of one stretchable knitted piece continuously knitted with different denier upper and lower portions However, there has been proposed a garment such as a leotard or a swimsuit (Japanese Utility Model Publication No. 60-86515) characterized in that the upper half of the waist line and the lower half of the elastic stretchable yarn are formed. Since the clothing has threads with different elastic forces that switch at the same time near the waist, the shape of the body around the waist is uneven at the boundary between the lower part with strong elastic force and the upper part with weak elastic force. However, when the knitted fabric was dyed, parts having different stretching forces were in a bunkering state (unevenness), which was a big problem in appearance and sewing.

(Problems to be Solved by the Invention) The present invention provides a knitted fabric interwoven with two or more kinds of elastic fiber yarns having different elastic forces and a non-elastic fiber yarn, which is a swimsuit,
When used for clothes such as leotards that require a figure-correcting effect, the elastic knitted fabric has an excellent figure-correcting effect and is suitable for clothing that requires a figure-correcting effect in which the correction site does not show an uneven appearance. Aim to get.

(Means for Solving the Problems) The present invention is to interwoven a non-stretchable fiber yarn and two or more types of stretchable fiber yarns having different stretching forces, whereby a portion including a high stretchable yarn and a low stretchable yarn are stretched. A knitted fabric forming a portion including a force yarn, wherein a band portion of the high elastic yarn and a band portion of the low elastic yarn are alternately mixed in a boundary portion between the both portions, and the band portion of the high elastic yarn is The width of the low elastic yarn is gradually reduced toward the portion including the low elastic yarn, the width of the band portion of the low elastic yarn is 5 mm or less, and the knitted fabric is continuously knitted without a switching portion. It is a stretchable knitted fabric.

In the present invention, non-stretchable fiber yarns interwoven with two or more types of stretchable fiber yarns having different stretching forces are various synthetic fiber yarns,
Natural fiber yarn is used. In the case of circular knitted fabric, 100% yarn of cotton, acrylic, etc., cotton / acrylic blended yarn, cotton / polyester blended yarn is preferred, and the thickness is 30s / 1-5 in cotton count.
0s / 1 is preferred. In the case of a warp knitted fabric, long-fiber yarns such as nylon and polyester are preferable, the thickness is preferably 30 to 70 denier, more preferably 40 to 50 denier.

The elastic yarn is preferably a polyurethane elastic yarn, and in this case, either a polyether type polyurethane elastic yarn or a polyester type polyurethane elastic yarn may be used.
Polyester type polyurethane elastic yarn with strong chlorine resistance is suitable for wearing in water. Stretchable fiber yarns having different stretching forces may be obtained by any method, but it is preferable to change the thickness of the yarns to give different stretching forces. For low stretch yarns, 20-40 denier is preferred. If it is less than 20 denier, the stretching force when the yarn is stretched by 300% is 10 g or less, and the stress in the fabric becomes too weak, resulting in poor fit feeling. If it exceeds 40 denier, the stretching force is 20 g or more at 300% elongation and the stress in the fabric is sufficient, but it is difficult to make a difference with the highly stretchable yarn, which is not preferable. Also,
For high stretch yarns, 50 to 140 denier is preferred. If it is less than 50 denier, it will be difficult to make a difference with low elasticity yarn, and if it exceeds 140 denier, the elasticity will be 40% at 300% elongation of the yarn.
It is not preferable because it exceeds g and the stress in the fabric is too strong, and it becomes difficult to nit especially in a warp knitted fabric. Further, particularly in the case of circular knitted fabric, a composite yarn of a stretchable yarn and a non-stretchable yarn such as a covering yarn core yarn may be used as the stretchable yarn. In the case of circular knitting, the knitting structure is preferably flat knitting or rib knitting,
For warp knitting, double denby, half and satin are preferable.
In this case, the knitted fabric parts having different stretching forces and the boundary parts having different stretching forces have the same appearance in order to make the appearance of the knitted fabric when worn and the unevenness of the body shape compensating portion as uniform as possible, and to facilitate the operation during knitting It is preferably knitted in a knit structure. The gauge of the knitting machine to be used is preferably 24 to 28 gauge for flat knitting, 18 to 24 gauge for rib knitting for circular knitting machine, and 24 to 28 gauge for warp knitting.
32 gauge is preferred. As a result of conducting various studies to minimize the puckering phenomenon of the knitted fabric and the uneven state during wearing at the boundary part, where two types of elastic yarns with different elastic forces are switched. When changing one step, the other thread is 5 m
It was found that when a large number of bands with a width of m or more were placed in a band-like shape, a puckering condition occurred, and this tendency was exhibited when the other yarn had a large elastic force. It was also found that, even when the other yarn is 5 mm or less, placing a yarn having a small elastic force in a band shape in a portion where a yarn having a large elastic force is present causes less puckering than the opposite case. As a result of further study using these findings, as shown in FIG. 1, in the interlaced knitted fabric 1 of the non-stretchable fiber yarn and the stretchable fiber yarn, from the portion A including the high stretchable yarn to the low stretchable yarn. In order to change the elastic force of the knitted fabric in a stepwise manner by arranging a portion where both elastic yarns are mixed between the portions B including the boundary portion C, the width of the band-shaped portions B _{1 to} B ₆ of the low elastic yarn is Is preferably 5 mm or less and the widths of the band-shaped portions A _{1 to} A ₆ of the highly elastic yarn are gradually reduced. Further, the band-shaped portions A _{1 to} A _n and the band-shaped portion B ₁
The width ratio to B _n is A ₁ : B ₁ = 4 to 5: 1, A ₂ : B ₂ = 3: 1,
_{A 3: B 3 = 2~2.5:} 1, A 4: B 4 = 1.5~1.8: 1 ...... A n: B n =
The width A _n of the last band part that connects to part B, such as 1: 1
And B _n are preferably equal. Further, it is preferable that the total number of band portions and the width of the band portions are changed depending on the knitted fabric use site or size of the final product obtained by using the knitted fabric. For example as the abdomen, the protruding portion of the abdomen relatively large number of bands and the number A ₄ A ₅ to boost smoothly to waist top, the hip lifting soft force, the number of bands A ₁ A ₂ in the opposite It is better to raise the buttock with a lot of hard force. Further, the arrangement of the portion A including the high-elasticity yarn, the portion B including the low-elasticity yarn, and the boundary portion C in which they are mixed may be arranged in any order and can be obtained by using the knitted fabric. It may be appropriately determined depending on the knitted fabric use portion of the final product. For example, as shown in FIG. 2, knitting a knitted fabric having portions with different stretching forces of A, B, and C and sewing the swimsuit shown in FIG. 3 prevents the chest from descending due to the A portion under the chest, and the abdomen. The protrusion of this portion is pushed up by C and B on the upper portion by the A portion of.

(Example) Example 1 1 needle bed warp knitting machine 28 gauge, 3 reeds were used, nylon 50 denier 12 filament plelite deformed yarn was arranged as a non-stretchable yarn, and polyester type polyurethane elastic was used as a high stretchable yarn. 70 denier yarn is arranged, and 40 denier polyester type polyurethane elastic yarn is arranged as a low elastic force yarn.
A knitted fabric with a half knitting structure for obtaining the swimsuit shown in the figure was knitted. The yarn arrangement at this time was 50 denier full set front reed nylon yarn, 70 denier middle reed polyurethane elastic yarn and 40 denier rear reed 〃, and the middle reed and rear reed yarns were combined into a full set. Also,
The arrangement of the portion A including the high-elasticity yarn, the portion B including the low-elasticity yarn, and the boundary portion C in which they are mixed is as shown in FIG.

Dyeing (95 ° C x 60 minutes) -Washing (50 ° C x 10 minutes) -Dehydration-Finishing set (170 ° C x 30 seconds) The density of the finished knitted fabric obtained is 108 courses / inch and 56
Course / inch, and the width of the low stretchable yarn portion B of the basic rear reed was about 3.6 mm. A one-piece swimsuit as shown in FIG. 3 was produced using only the knitted fabric obtained as described above (without lining). The swimsuit prevents the chest from going down by the A-1 portion under the chest and pushes the chest upward, and the protrusion of this portion is pushed up by the chest A-2 portion to the upper portion B and C ₂ portions. As a result, it has an excellent shaping effect, and has a shaping effect similar to that of a conventional lined swimsuit. It also had excellent stretchability, and was extremely removable.

Example 2 Using a 28-gauge single circular knitting machine, acrylic / cotton spun yarn 30'S / 1 (mixture ratio acrylic / cotton = 60/40) was arranged as a non-stretchable yarn, and as a stretchable yarn, Example 1 was used. 70 denier and 40 denier polyester type polyurethane elastic yarns similar to the above were arranged to form a knitted fabric for swimming to obtain the swimsuit of FIG. Further, the arrangement of the portion A containing the high-stretchability yarn, the portion B containing the low-stretchability yarn, and the portion C containing them mixed was the same as in Example 1. Further, the number of basic low-elasticity yarns is 6, and the boundary C _{1 of the} part corresponding to the buttocks, the boundary C _{2 of the} part corresponding to the waist and the boundary C _{3 of the} part corresponding to the lower part of the chest.
The use ratios of the high-stretch yarn and the low-stretch yarn at C ₄ were the same as in Example 1. The obtained knitted fabric was subjected to unfolding-preset (175 ° C, 30 seconds) -scouring (80 ° C, 40 minutes) -finishing set (170 ° C x 30 seconds). The density of the obtained knitted fabric was 58 courses / inch, 40 wales / inch, and the width of the basic low stretchable yarn portion B was about 3.8 mm. When a one-piece swimsuit similar to that of Example 1 was produced using only the knitted fabric (without lining), the same effect as that of Example 1 was observed.

(Effects of the Invention) In the stretchable knitted fabric of the present invention, the high stretchable part and the low stretchable part are continuously knitted without having a switching part, and therefore, the knitted fabric is used for clothes such as swimwear and leotards. When you make, the unevenness is not expressed, and the stretchable parts have different stretchable forces in stages, so the body shape correction effect is great,
A knitted fabric suitable for clothing such as swimwear and leotards. Further, since yarns having different stretching forces coexist at the boundary between the high stretchable portion and the low stretchable portion, the body shape adjusting effect can be exerted more effectively.
