Definitions

  • the present invention relates to kitchen paper and kitchen paper products that are used for cleaning purposes and for touching ingredients.
  • Kitchen paper is used for cleaning the kitchen, cleaning utensils, etc., food packaging, boiled drop lids, drip absorbents such as fresh fish, water drainers, oil sachets, and fried foods. Although it is used for various purposes such as direct contact, liquid absorption, hygienic safety, and hygienic design are essential.
  • oil or water is quickly applied so that the fried foods are not damaged by steam or oil from the fried foods.
  • a function of absorbing or diverging and preventing the oil once absorbed from returning to the deep-fried food is also required.
  • an appropriate number of sheets made of embossed crepe paper are laminated and formed as a liquid absorption mechanism mainly due to a capillary phenomenon due to a gap between sheet fibers in a gap between embosses of each sheet.
  • Known are those configured to take in and hold moisture, oil, and the like, and those formed only from a nonwoven fabric sheet, in which moisture, oil, etc. are taken in and held in the gaps between the nonwoven fabric fibers.
  • crepe paper is dense between fibers and oriented in the MD direction in the plane direction, and the valley of the crepe extends in the CD direction, so water / oil absorption in the plane direction is faster compared to the nonwoven sheet, Absorption and transmission in the Z-axis direction are slow due to high density.
  • the laminate of the above-mentioned crepe paper does not have the thickness of the whole kitchen paper compared to the nonwoven fabric sheet, and the liquid is diffused due to the high orientation of the fibers in a certain direction due to the manufacturing process.
  • kitchen paper may be a product in a roll form.
  • the user cuts and uses the perforated line appropriately arranged.
  • the crepe paper tends to have a higher paper strength when compared with the nonwoven sheet, and the kitchen paper in which the crepe papers are laminated has a higher perforation strength than that using the nonwoven sheet. There is a tendency. For this reason, compared with the thing of the nonwoven fabric sheet, it was difficult for consumers to cut at the time of use. Although it is possible to simply reduce the paper strength of the crepe paper for improving the cutting performance at the perforation line, it becomes a brittle kitchen paper with no strength, and it tends to cause problems in various other applications. .
  • crepe paper has fine creases on its surface. This cocoon is necessary because it functions importantly in terms of liquid absorption and wiping properties when used as kitchen paper, but it has a hygienic impression due to this cocoon compared to the non-woven sheet. There is a property that it is difficult to increase whiteness, which acts greatly, and it is difficult to obtain smoothness of the surface.
  • the kitchen paper consisting only of the nonwoven fabric sheet is easy to permeate although it has a very high liquid absorption speed due to the coarse fiber density and the large number of voids between the fibers due to the manufacturing method of the nonwoven sheet.
  • the liquid retainability is extremely inferior to that of kitchen paper laminated with crepe paper. Due to this property, the crepe in which the fibers are strongly oriented in a certain direction also in terms of diffusibility within the liquid sheet. Inferior to paper.
  • kitchen paper consisting only of non-woven sheets has a coarse fiber density and a large number of gaps between the fibers, so that dry dust and dust can easily be taken into the gaps in a dry state.
  • it is excellent in comparison, it is not suitable for cleaning use such as spilled cup water or sewage absorption, wiping use, etc., because the above-mentioned moisture retention is poor and the back of the liquid and the return of the liquid are not suitable.
  • water wiping applications it was difficult to maintain a suitable wet state as compared with crepe paper in which the fibers are dense and oriented strongly in a certain direction.
  • kitchen paper made of only a non-woven sheet cannot be made thin because the fiber dispersion in the thickness direction inevitably increases compared to crepe paper due to the manufacturing method. Furthermore, kitchen paper consisting only of non-woven sheets can be good in terms of whiteness because the non-woven sheets are thick and have high cushioning properties, but embossing (embossing) does not enter firmly. It is difficult to enhance the design to give a hygienic impression by applying the design.
  • the impression of the smoothness of the surface is inferior to the crepe paper because it is inferior in friction, but is suitable for wiping off sticky dirt.
  • kitchen paper with only a non-woven sheet has the advantage of being easy to cut by the perforation line, but it is necessary to take a long tie part at the perforation line to prevent unintentional cutting.

  • the nonwoven fabric sheet may tear when the sheet is wound with a winder after lamination at the time of manufacture, which is difficult in terms of workability.
  • the bonded part by the adhesive hindered the absorption and permeation of water / oil, and the function of the base material was not necessarily fully utilized.
  • the adhesive agent is absorbed by the nonwoven fabric, and both are insufficiently bonded. The sheet tends to become hard due to the application of the adhesive.
