  However, each of the proposed cleaning cloths uses acrylic fibers and loop pile fabrics to take advantage of the breathing action of acrylic yarns due to the expansion and contraction of the woven fabric itself. Even if the effect was enhanced, no other side effects could be expected.

  In view of the actual situation as described above, the present invention is mainly used for a cleaning cloth, further seeks a massage effect in addition to cleaning, and reveals a three-dimensional effect due to unevenness on the cloth itself, thereby cleaning cloths such as body towels and dirt towels. An object of the present invention is to provide a knitted cloth that not only makes it easy to remove dirt due to the uneven surface of the contact surface, but also provides a massage effect.

  That is, the knitted cloth of the present invention that meets the above-mentioned purpose is formed by inserting insertion yarns between the respective stitch rows in the chain stitch row of the required width, and the insertion yarns in the wale direction in units between adjacent stitch rows. A plurality of course positions are shifted, and a plurality of courses are swung across each stitch row to move between adjacent stitch rows, and a plurality of courses are swung across the adjacent stitch rows to return between the original stitch rows. By repeating the horizontal swing of the course, an insertion yarn inserted between the stitch rows between the stitch rows and a horizontal swing portion by the insertion yarn transferred from between the adjacent stitch rows are alternately formed and one row A pattern yarn made of heat-shrinkable synthetic fiber bundling yarn is inserted vertically between every three rows of stitches, and is passed between the alternately formed horizontal swinging portions from above and below, and the pattern yarn is contracted to cross. Concave with pattern thread shrunk on both sides Consisting of sensible put out tighten formed by constituting a handle pattern.

  Here, known yarns can be used as the yarn forming the chain stitch row, but generally one or two or more types selected from polyester, nylon, rayon and cotton yarn are used, especially polyester. Spun yarns are preferred, and known yarns can be used as inserted yarns that are folded back into the chain stitch rows. Usually, one or more types selected from cotton yarn, acrylic yarn, nylon, and polyester yarn are used. A polyester spun yarn or cotton yarn which is used in combination and is the same as the chain stitch forming yarn is particularly suitable.

  In addition, the pattern yarn made of heat-shrinkable fiber bundling yarn that is inserted vertically between every three rows of chain stitches and penetrated is selected from nylon, hollow nylon, polyester, and acrylic having heat-shrinkability. Further, one or more kinds of them, or their aligned yarns such as woolly processed yarns and microfibers are used. The pattern yarns composed of these chain stitch row forming yarns, insertion yarns, and heat-shrinkable synthetic fiber bundling yarns may be the same color, but if they are different colors, a beautiful appearance can be obtained due to the design effect. In particular, for nylon, polyester, etc., it is effective to use microfibers, ultrafine composite fibers, etc. according to the use of the cloth.

  A fifth aspect of the present invention is a method of manufacturing the knitted cloth, wherein in a chain stitch row having a required width, the insertion yarn is inserted between each stitch row and the position is shifted in the wale direction as a unit between the two stitch rows, and a plurality of course crossings are respectively provided. Swing to move between adjacent stitch rows, swing multiple courses between adjacent stitch rows, return to the original stitch row, repeat the multiple courses, and repeat between the stitch rows between the stitch rows A plurality of transverse courses are formed alternately by the inserted yarn inserted between the inserted yarn and the adjacent stitch row, and heat shrinkability between every three or three rows of chain stitch rows over the entire width required. A pattern yarn made of synthetic fiber bundling yarn is vertically inserted, and the raw fabric knitted fabric is created by letting it penetrate from above and below by the horizontal swinging part of multiple courses with both insertion yarns formed alternately between the above stitch rows Then, the raw knitted fabric is heated to Contract the pattern yarn made of the heat-shrinkable synthetic fiber roving yarn which is characterized by a method which occupies put out sensible irregularities pattern pattern due 該柄 yarn shrinkage in the cross sides.

  In addition, although heat processing temperature is not uniform by the heat-shrinkable synthetic fiber to be used, normally suitable temperature is selected from the range of about 110 to 200 degreeC.

  As described above, according to the present invention, between the stitch rows in the chain stitch row of the required width, the horizontal swing portion by the insertion yarn between the stitch rows and the horizontal swing portion of the insertion yarn transferred from between the adjacent stitch rows are provided. In addition to forming alternately, a pattern yarn made of heat-shrinkable synthetic fiber bundling yarns between every other one to three rows of stitches is sandwiched from above and below between the horizontally swung portions of both of the alternately formed yarns. It is made to shrink by heat treatment and heat treatment, and the concavo-convex pattern is revealed on the front and back of the cloth by the pattern yarn by the shrinkage. It penetrates the horizontal swing part and is pressed by the horizontal swing part from above and below alternately. The feeling is clearly manifested, and when used on body towels or dirt towels, etc., compared to flat surfaces and pile surfaces, it has a good feeling due to a three-dimensional feeling and has a stimulating massage effect, as well as a towel Dirt due to unevenness even when used It has an easy advantage and. Moreover, every other row or every two or three rows between the chain stitch rows, and by forming irregularities due to shrinkage in a lattice or checkered pattern, a lattice pattern or a checkered pattern is formed on the entire surface, and it is distorted. A beautiful design effect can be obtained.

It is a general-view figure which shows one example of the cloth which concerns on this invention. It is a partial expanded organization chart of a cross of Drawing 1, (a) is a top view, (b) is a XX section outline figure, (c) is a YY section outline figure, (d) is a ZZ section outline. FIG. It is the partial expanded organization chart which shows the other example of this invention cloth, (A) is a top view, (B) is a X'-X 'cross-sectional schematic diagram, (C) is a Y'-Y' cross-sectional schematic diagram, (D) is a schematic view of a Z'-Z 'cross section.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic external view showing an example of a knitted cloth according to the present invention. In the figure, A shows a cross body, and each chain stitch row a made up of chain stitch forming yarns 1 of a required width arranged in parallel as shown in the figure. A horizontal swing portion is formed between the inserted yarns, and the handle yarn 4 made of heat-shrinkable synthetic fiber bundling yarn passes through the horizontal swing portion so as to be sandwiched from above and below, and contracts by the heat passing portion c and heat treatment. The bulged protrusions b are alternately formed, and a pattern pattern with unevenness is revealed on the front and back of the cloth.

  FIG. 2 shows the details of the above structure. In each chain stitch row a formed with a required width, the horizontal swing portions 3, 3 ′ are inserted by inserting yarns 2, 2 ′ between the adjacent stitch rows. Is formed. The horizontal swing portions 3 and 3 'are alternately formed between the stitch rows together with the insertion yarns 2 and 2' between the adjacent stitch rows, and the adjacent insertion yarns 2 and 2 'are arranged between the adjacent stitch rows. After shifting several courses in the wale direction as a unit and folding back over a plurality of courses between each row, moving between adjacent stitch rows, performing a transverse turn over a plurality of courses between the stitch rows, and then returning to the original A zigzag knitting is performed in which a plurality of courses are swung back and forth between the stitch rows, and the horizontal swing portions 3, 3 'for each of the plurality of courses by the insertion yarns 2, 2' adjacent between the stitch rows as described above. Are formed alternately.

  Then, the pattern yarn 4 made of heat-shrinkable synthetic fiber bundling yarns is passed through between the alternately formed stitch rows between adjacent stitch yarns 2, 2 'so as to be sandwiched between the upper and lower sides of the horizontal swing portions 3, 3'. Are formed between the alternately formed horizontal swinging portions 3 and 3 ′, a portion appearing on the front surface side and a portion appearing on the lower surface side, and are inserted every other row in the vertical direction in the figure. Of course, it is not limited to every other row, but every second row or every third row may be used. However, since the beauty of the pattern pattern is lost when the interval becomes too large, about 1 to 3 rows are preferable.

  The knitted fabric knitted as described above is a raw fabric knitted fabric, and by subsequent heat treatment, the exposed portion of the patterned yarn 4 made of heat-shrinkable synthetic fiber bundling yarn is thermally contracted and bulges in a loose state. As a result, a concavo-convex pattern is formed together with the handle yarn bulging portion b bulging between the underpass portions c, and a three-dimensional effect is revealed. In FIG. 1 and FIG. 2, the bulging portion b is in a vertical and horizontal line between adjacent stitch rows, and irregularities due to a lattice pattern are formed on the entire surface, but this is not necessarily limited to this pattern. It is also possible to sandwich the stitches alternately between adjacent stitch rows so that the bulging portion appears in a checkered pattern.

  FIG. 3 shows a case where the bulging portion is sandwiched in a checkered pattern, and is the same as in FIGS. 1 and 2 except that the sandwiching position is different. In addition, various uneven patterns can be obtained by appropriately changing the sandwiching position.

  In each of the above crosses, any yarn can be used for the yarn forming the chain stitch row, the insertion yarn inserted into the chain stitch row, and the pattern yarn inserted between the chain stitch rows. Specifically, the yarn forming the chain stitch row is preferably a spun yarn such as polyester, nylon, rayon, cotton yarn, and preferably knitted using these alone or in combination of two or more. Cotton yarn, acrylic, nylon, and polyester are mainly used as the insertion yarn that is inserted into the chain stitch row in a horizontal manner. Both of these insertion yarns may use the same yarn as the chain stitch forming yarn. In particular, it may be preferable to use different types of yarns in terms of texture, color difference appearance due to dyeing, and the like. In general, about 20th single yarn is effective as the spun yarn.

  On the other hand, as the heat-shrinkable synthetic fiber bundling yarn of the handle yarn inserted between the chain stitch rows, a thick-lined bundling yarn is used which is a single or mixed arrangement of heat-shrinkable nylon, polyester and acrylic fibers. , By shrinking by heat treatment, it exhibits a Mole yarn shape, sandwiched between the upper and lower horizontal swinging portions 3, 3 'that appear alternately on the front and back of the cloth, the shrinking and converging yarn that appears on the surface is on the surface side, On the other hand, the shrinking and converging yarns revealed on the back surface bulge in the back surface side in a loose state, and give the three-dimensional impression of the present invention on the cross front and back in a lattice or checkered pattern as shown in FIGS. .

  In practice, it is practical to use as the handle yarn 4 eight microfiber yarns by splitting polyester / nylon composite yarns, hollow nylon multiple yarns, woolly nylon or polyester multiple yarns. Is effective.

  In producing the cloth of the present invention, a single Russell machine is usually used, and the chain stitch rows are knitted in parallel at a required width by the knitting machine, and an insertion thread is used between each chain stitch row, and After shifting the position by a plurality of courses in the wale direction between adjacent stitch rows and swinging a plurality of courses to form a horizontal swing portion, it moves between adjacent stitch rows, and a plurality of the same as described above between the stitch rows. Inserted yarn inserted between stitch rows adjacent to each chain stitch row by repeating the process of swinging back and knitting in the course of knitting, returning to the original stitch row and then swinging in this stitch row again The horizontal swing portions of a plurality of courses by one of the two are intermittently knitted at intervals of a plurality of courses in the vertical direction, that is, the wale direction, while the other insertion yarn adjacent between the stitch rows is the intermittent knitting. Left intermittently by First, a plurality of courses are swung across each stitch row so as to fill the positions corresponding to the plurality of courses, and then the portions are intermittently left between the adjacent stitch rows to fill the portions. The horizontal knitting is performed as described above, and then a plurality of courses are swung back by returning between the original stitch rows, and this is repeated between all the stitch rows. A knitted fabric base fabric in which the horizontal swing portions are alternately and repeatedly arranged is created.

  And together with the knitting of the knitted fabric base fabric by the single raschel machine, a pattern yarn made of heat-shrinkable synthetic fiber converging yarn is inserted between every other row or every second or third row between the stitch rows, A plurality of courses of a horizontal swing portion formed between stitch rows and a horizontal swing portion formed by an insertion yarn inserted between adjacent stitch rows alternately arranged with the horizontal swing portion Then, a raw machine knitted fabric is created in which pattern yarns alternately appear between the underpass portions on the front and back sides of each stitch row of the knitted fabric.

  That is, as shown in FIGS. 2 and 3, the heat-shrinkable synthetic fiber focusing yarns pass through the horizontal swing portions 3 and 3 'by the insertion yarns 2 and 2' between the alternately formed stitch rows. The formed pattern yarn 4 is sandwiched between the laterally swinging portions 3 and 3 ′ alternately formed as the longitudinal insertion yarn, forming a portion that appears on the surface side and a portion that appears on the lower surface side by the underpass portion. ing.

  When the green machine is knitted in this manner, the patterned yarn 4 comprising the heat-shrinkable synthetic fiber bundling yarn is then heat-treated at a temperature suitable for each yarn used in the range of 110 ° C. to 200 ° C. The heat shrinks, the yarn bundle breaks up and bulges out to form a convex portion, and the concave and convex three-dimensional effect is revealed together with the concave portion by the penetration portion. In FIGS. 1 and 2, the bulging portions b are on one line between adjacent stitch rows, and irregularities due to a lattice pattern are formed on the entire surface. As described above, it can be pinched and revealed in a checkered pattern. Examples of the present invention will be further described below.
