Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a soft bundle that is optimal for tableware, cooking utensils, kitchen equipment, etc., especially for cooking utensils with special surface treatment such as silver stone processing and Teflon processing (hereinafter simply referred to as special processing cooking utensils). .

[0002]

[Prior art]

 Conventionally, as the ones with improved rubbing ability, there are turtle bunches that bundle the hair of palms, metal bunches, and non-woven cloth bunches containing abrasives (white aluminum oxide, garnet, emery silica, etc.). Examples of such products include soft urethane foam sponge and cellulose sponge.

[0003]

[Problems to be solved by the device]

 As for the specially-prepared cooking utensils that have been widely used recently, the conventional cooking utensils have the following problems.

That is, the former one having an improved rubbing ability has a problem that although the dirt is very well removed, the working layer is scratched, or the working layer disappears early due to surface abrasion or the like. .

Further, the latter one that attaches importance to softness has a problem that it is difficult to remove sticky and stubborn dirt, although it is not scratched.

An object of the present invention is to provide a soft bundle that can be easily removed from the specially-crafted cooking utensil without damaging the surface of the utensil even with sticky and stubborn stains.

[0007]

Means for Solving the Problems In order to achieve the above object, a soft bundle according to the present invention has a surface of a bundle main body and a constituent fiber in which a foamed thermoplastic resin layer is provided on one surface of a synthetic fibrous nonwoven fabric mat. A soft bundle having a coating layer made of a thermoplastic resin formed on the surface, wherein the foamed thermoplastic resin layer is a layer obtained by foaming a thermoplastic resin by thermal expansion of a thermally expandable microcapsule. Content of 20 to 50 (parts by weight) based on 100 parts by weight of the thermoplastic resin. When the content of the heat-expandable microcapsules in the foamed thermoplastic resin layer exceeds 50 parts, the strength of the bundle itself decreases and a problem arises in durability. Not only does it not sufficiently foam, the unevenness disappears and the cleaning power decreases, but the product lacks in design.

The coating layer can be made of a mixed resin of a thermoplastic resin and a thermosetting resin to improve the softness of the bundle.

[0009]

[Action]

 When the soft bundle of the above construction is used, the cushioning property of the thermally expanded microcapsules in the foamed thermoplastic resin layer and the hardness and durability of the covering layer that covers the foamed thermoplastic resin layer adapts to the dirt that has stuck and provides sufficient cleaning power. Exert. Further, since no abrasive material is used, the surface of the special processing control tool is not damaged even during cleaning and rubbing. In addition, the foamed thermoplastic resin layer foamed by the thermal expansion of the heat-expandable microcapsules has a large number of closed cells, giving it an uneven appearance and a very soft texture, so the curved surface of the object to be cleaned is It can be applied and washed well even on the corners and corners.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

[0011] A random resin or crossweb having a basis weight of 130 g / m ² consisting of nylon fiber 14 d × 38 m / m, 100% and an aqueous resin consisting of 40 parts of polyvinyl alcohol resin and 60 parts of melamine resin has a DPU of 65% [( Weight after impregnation-weight before impregnation) / weight before impregnation × 100] (hereinafter referred to as DPU) Impregnation is performed, and 140 g / m ^{2 is} spray-processed on both sides with an emulsion of 100% SBR resin to give a basis weight of 240 g / m 2. ^Two non-woven mats were obtained. On one side of the above-mentioned non-woven fabric mat, 170 g / m ^{2 of} water-based resin consisting of 30 parts (parts by weight) of heat-expandable microcapsules for 100 parts (parts by weight) of SBR resin was sprayed and dried at 100 ° C for 10 minutes. after, and heated 140 ° C. × 5 minutes, a scrub brush body having a basis weight of 413 g / m ² which due to thermal expansion of the thermally expandable Ma cycle capsules cause foaming and curing of SBR resin to form a foamed thermoplastic resin layer Obtained. Next, the bundle main body was impregnated with an aqueous resin composed of 100 parts of SBR resin and 20 parts of melamine resin at a DPU = 50% to obtain a soft bundle having a basis weight of 620 g / m ² .

As shown in FIG. 1 and FIG. 2, the soft bundle of the present invention obtained by the above-mentioned embodiment contains synthetic fibers (1) such as nylon, polyester, polypropylene, vinylidene chloride, acrylic, etc., respectively. Alternatively, a web made of a mixture of a plurality of types is coated with a resin such as vinylidene chloride or acrylic on one surface of a non-woven mat that has been impregnated and sprayed with a thermoplastic resin such as a resin selected from acrylic, SBR, NBR and PVA. A thermoplastic resin (4) foamed by thermal expansion of a thermally expandable microcapsule (3) containing a low boiling hydrocarbon as a wall, for example, a bundle main body (2) provided with a foamed thermoplastic resin layer (5) of SBR resin. Formed. Further, the bundle main body (2) is impregnated with a resin binder containing a thermoplastic resin (eg, SBR, NBR, acrylic ester, EVA, etc.) as a main component and a thermosetting resin such as melamine, epoxy, phenol, etc. mixed. Then, a coating layer (6) was formed on the surface of the bundle main body and its constituent fibers to form a desired soft bundle.

By the way, the compounding ratio of the thermosetting resin constituting the coating layer (6) is appropriately determined depending on the application. In addition, the coating layer (6) may be formed of a thermosetting resin-rich or thermosetting resin alone for an object to be cleaned in which dirt is not easily removed.

Comparative Example 1 One side of the above non-woven fabric mat was spray-processed with a solvent-based resin consisting of 80 parts of a phenol resin, 20 parts of an epoxy resin, 100 parts of garnet sand and 100 parts of aluminum hydroxide at 170 g / m ² and a basis weight. A non-woven fabric bundle of 413 g / m ² was obtained.

[0015] one surface of (Comparative Example 2) The non-woven mat, 80 parts of phenol resin, and 170 g / m ² spray process a solvent-based resin consisting of 20 parts of an epoxy resin, to obtain a nonwoven scourer basis weight 413 g / m ^2.

[0016] one surface of (Comparative Example 3) The nonwoven mat, 17 0 g / m ² was spray process an emulsion consisting of 100 parts of SBR resin, to obtain a nonwoven scourer basis weight 413 g / m ^2.

[0017] one surface of (Comparative Example 4) The non-woven mat, 100 parts of SBR resin, foamed water-based resin 170 g / m ² was spray process consisting of the resin 30 parts, to obtain a nonwoven scourer basis weight 413 g / m ^2.

Hereinafter, using the bundles obtained in Examples and Comparative Examples, an aluminum plate subjected to silver stone processing and a burned aluminum plate were rubbed 1000 times back and forth with a load of 500 g / m ² , and then silver stone When the degree of scratches on the processed surface and the degree of stain removal were visually compared, the results shown in the table below were obtained.
