Description

  The present invention is a cloth for wiping suitable for use in wiping, which is mainly used for kitchens, such as around a range, a table, and particularly recently, with the spread of electromagnetic cookers, in addition to the removal of dirt and the need to not damage the main body. It is about.

  Conventionally, a cloth made of 100% cotton has been generally used as a cloth for wiping off dirt in a home kitchen or the like, but a cloth made of cotton is water-absorbing but its fibers are relatively thick and inferior in wiping off dirt. For this reason, wiping cloths using a rayon wiping cloth, a non-woven fabric using microfiber (microfiber) or a knitted fabric have been proposed. (For example, see Patent Documents 1, 2, and 3)

  However, the rayon wiping cloth has an edge effect because the cross-section of the rayon fiber is rectangular and flat, and it is effective for removing dirt. However, the thick fiber removes fine dirt and dust. There are difficulties that are not enough.

  On the other hand, wiping cloth using extra fine yarn is effective in removing fine dirt and dust because the fibers are thin, and it has the advantage of not damaging the surface, but the dirty color is interspersed and it is difficult to wash off with water. When used for a while, it looked bad, and there was a problem in appearance and it was difficult to wipe off.

  In view of the actual situation as described above, the present invention absorbs and incorporates the advantages of the rayon yarn and the extra fine yarn in particular, and enhances the practical effect of the wiping cloth, and further uses a dark colored yarn for the extra fine yarn. The purpose is to make it inconspicuous.

  That is, the wiping cloth of the present invention suitable for the above-mentioned object includes a chain stitch row made of rayon yarns extending in parallel in the warp direction, and stitches in a stitch row separated by a plurality of rows in the weft direction from the stitches of each row of the stitch rows. The warp knitted fabric structure is knitted by a weft insertion yarn made of synthetic fiber yarns folded back and forth in a zigzag manner, and between the adjacent stitch rows in each of the juxtaposed stitch rows of the ground texture It is formed by warp knitted fabric obtained by alternately folding back and knitting a flat rayon yarn having a rectangular cross section and a polyester / nylon separable composite fiber as a pattern yarn.

  Claim 2 is a more specific wiping cloth, a chain stitch row made of rayon yarns extending in the warp direction in parallel, and a plurality of rows in the weft direction from each stitch in the warp direction in each row of the stitch rows The base fabric structure is knitted by the weft insertion yarns made of synthetic fiber yarns that are folded back and zigzag between the intermediate stitches of the stitch rows, and the chain stitch rows 3 of the base fabrics arranged in parallel are arranged. The pattern yarns are entangled with each other without the first and second pattern yarns crossing the stitches in the middle row by shifting the position of the first stitch in the warp direction between the adjacent stitch rows facing each other in units of rows. The first and second handle yarns are flat rayon yarns having a rectangular cross section and ultrafine yarns made of polyester / nylon split composite fibers, which are alternately used and are intertwined to face each other. Flat layo with patterned yarn alternately It is formed by warp knitted fabric in which yarns or extra fine yarns are linearly exposed and appear in a pile shape, and on the surface, pile ridges of flat rayon yarn and extra fine yarn are alternately revealed. It is characterized by the structure.

  Here, a rayon spun yarn is preferable as the yarn forming the chain stitch row, and various synthetic fiber yarns such as nylon, polyester, polyacryl fiber, etc. can be used as the synthetic fiber yarn inserted into the stitch row. Polyester fiber yarn is practically preferred. In addition, it is preferable to use a flat rayon yarn having a rectangular cross section as a handle yarn and an ultrafine yarn obtained by splitting a polyester / nylon split type composite fiber in view of the synergistic effect of both the fiber yarns. It is extremely effective to use the dyed yarn that is dyed to make the dirt as a wiping cloth inconspicuous.

  As described above, the wiping cloth of the present invention is a warp knitted fabric base cloth in which a cross-sectionally rectangular flat rayon yarn and polyester / nylon split-type composite fiber split ultra-fine yarn is used alternately between adjacent stitch rows. Using rayon yarn and polyester yarn for warp and weft of the base fabric to give moderate strength and flexibility as the base fabric, while the pattern yarn is a flat rayon yarn with a rectangular cross section and polyester / nylon split type Expected to have a synergistic effect with each yarn using ultrafine yarns by splitting composite fibers, and the same yarns were alternately entangled with each other, resulting in vertical stripes as an appearance, and also with pile-like ridges, each having a rectangular cross section The effect of scraping off by the edge effect of flat rayon yarns and the effect of removing fine dirt and dust by ultra fine fibers coexisted. Without damaging the body also, especially with the makes it good design when using dark yarn, extremely it has practical effect as fabrics wiping not be visibly dirty.

It is a figure which shows the insertion aspect of a weft insertion thread | yarn. It is a figure which shows the knitting structure of one pattern yarn. It is a figure which shows the knitting structure of the other pattern yarn. It is a structure | tissue schematic diagram which shows the entanglement aspect of both pattern yarns.

  Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall structural view showing an example of a wiping cloth according to the present invention. FIGS. 2 to 6 are views showing the structure of each constituent yarn. In these figures, 1 is a chain extending in the warp direction in parallel. The warp yarns 2 forming the stitch row a are inserted in a weft zigzag manner in a weft insertion between the chain stitch rows a in the weft direction and a plurality of chain stitch rows a in the weft direction in all the stitches in the chain stitch row a. A warp knitted fabric structure which is a yarn and forms a chain stitch row and a weft insertion yarn 2 is knitted into a warp knitted fabric structure, and three rows of chain knitted stitch rows a in which the warp knitted fabric structures are arranged in parallel As shown in FIG. 6, the first and second pattern yarns 3 and 4 are shifted by one stitch in the warp direction between the adjacent stitch rows from both sides, as shown in FIG. Without damaging the two patterned yarns, they are entangled with each other to create a pile-shaped ridge, Cloth to form a whole of warp knitted fabric. Here, as the chain stitch forming warp in the warp knitted fabric structure, natural fibers such as cotton and linen, and synthetic fibers such as rayon or nylon can be used. Practically, a rayon spun yarn of 15-30th yarn, preferably 20th single yarn is preferably used.

  On the other hand, there is no particular limitation on the weft insertion yarn 2 to be inserted into the chain stitch row of the above-mentioned texture, but most commonly, a polyester yarn of 500 to 800 dtex (preferably 660 dtex / 144 F) is used. Usually used.

As the pattern yarn 3 and 4 is inserted into the warp knitted fabric structure by the warp threads 1 and weft yarns 2, one flat rayon yarn Y ₁ is used, the other One polyester / nylon split An ultrafine yarn Y ₂ made of a composite fiber is used, and the flat rayon yarn Y ₁ and the ultrafine yarn Y ₂ are alternately used for the respective pattern yarns 3 and 4.

The flat rayon yarn used for the handle yarn is a flat rayon filament having a rectangular cross section, and a rayon filament having a rectangular cross section having an edge in particular is selected in order to remove dirt due to the edge effect. Such a rayon filament having a rectangular cross-section can be obtained by spinning by a known means using a nozzle having a rectangular spinning hole, and is a flat rayon yarn Y of 300 to 400 dtex, preferably 330 dtex / 30F. Used as pattern yarn as ₁ .

On the other hand, the microfibers Y ₂ consisting of polyester / nylon splittable conjugate fiber yarn is another pattern yarn is spun as a composite filament, is used to handle yarns as microfibers by being divided. As the composite filament to be spun, although the thickness of the ultrafine yarn varies depending on the number of divided filaments, a range of 150 to 200 dtex / 60 to 80 F is preferable, and a split type composite fiber yarn of 178 dtex / 64 F is usually used. The polyester / nylon split-type composite fiber yarn is further divided into individual fibers, which are patterned yarns as an aggregate of ultrafine yarns of 0.3 dtex or less. In this case, the polyester / nylon split-type composite fiber yarn is preferably dyed in a dark color and used as a dark color yarn in order to eliminate the noticeability of dirt as well as the design.

Thus, with respect to the both patterns yarns 3,4, respectively, in the warp direction between the parallel strands stitch row as shown in FIGS. 1 and 6 by using alternately the flat rayon yarn Y ₁ and fine yarn Y ₂ The yarns are knitted so that the two yarns are entangled with each other without crossing the stitches in the middle row between the adjacent stitch rows from both sides, with each other being shifted by one row in units of 3 rows. weaving so that both pattern yarn are the same flat rayon yarn or fine yarn alternately yarn so as to form alternating pile projections by both the entanglement by entangling and fine yarn Y ₂ by flat rayon yarn Y ₁ together In addition, the strips of the same flat rayon yarn or extra fine yarn are formed into a vertical stripe pile, and on the other hand, the extra fine yarn Y ₂ is a dark color yarn, and more distinctly different vertical stripes are exhibited. Good The cloth for wiping of the present invention is formed. Examples will be further described below.

  Using a 20th yarn for warp forming a chain stitch row with a Russell knitting machine, a single yarn rayon spun yarn, 660 dtex for the weft insertion yarn inserted into the chain stitch, and a 144 filament polyester yarn, Formed into a warp knitted fabric, 330 decitex as a pattern yarn to be inserted into the warp knitted structure, flat rayon yarn having a rectangular cross section of 30 filaments, and 178 decitex before splitting comprising a polyester / nylon split type composite fiber, After splitting with 64 filaments, an ultrafine fiber having a single yarn of 0.3 dtex or less was alternately used to prepare a wiping cloth of the present invention as shown in FIG.

  On the other hand, for comparison, a Russell knitting machine used 84 dtex and 36 filament polyester yarn for warp and weft insertion yarn, and used 330 dtex and 30 filament rayon yarn for the front and back piles as pattern yarn. The cloth for wiping was also made of polyester 110 dtex and 36 filaments for both warp and weft insertion yarns, and before splitting consisting of polyester / nylon split type composite fiber as pattern yarn, after splitting with 178 dtex and 64 filaments, single yarn 0.3 The wiping cloth of Comparative Example 2 was prepared using decitex ultrafine fibers. Then, in order to confirm the effect of each of the above-mentioned wiping cloths, a salt (made by Hakata Shiogyo Co., Ltd., salt of Hakata) was sprayed on a flat desk in an amount of 10 g per 25 × 25 cm square and wiped. Went.

  The table below visually confirmed the situation on the desk after wiping (the remaining amount of salt), and the number of remaining grams was measured with an electronic balance. The dry state is the state before wetting the wiping cloth, and when wiping off the salt. On the other hand, the wet state is the state when the wiping cloth is moistened with water and then wiped with water. .

  From the above experimental results, Comparative Example 1 is inferior to the present invention in both the dry state and the wet state as compared with Example 1 of the present invention, and the cloth for wiping of the present invention is superior. I understand. Moreover, although the comparative example 1 was able to scrape off dirt, since the fiber was thick, it was not possible to grab dirt, and it was not wiped cleanly compared with the cloth for wiping of the present invention.

  On the other hand, in the case of Comparative Example 2, it is almost the same in the dry state, but it is understood that the wet state is slightly inferior to the wiping cloth of the present invention. Moreover, in the case of Comparative Example 2, 100% of the microfiber yarn was used so that fine stains could be removed, but the entire fiber was softer, and the scattered salt was wiped away from the cloth for wiping the present invention containing rayon. It was much wider.
