Abstract

PURPOSE:To obtain a soft brush not damaging a surface processed with silver stone, Teflon(R) or the like even during the application of washing and rubbing processes by forming a foamed thermo-plastic resin deposit layer on one side of an unwoven mat made of synthetic fiber and impregnating and covering the deposit layer with thermo-setting resin. CONSTITUTION:The soft brush in the title is so constituted that a web compris ing independent or a plurality of mixed synthetic fibers 1, for example, nylon, polyester and the like is fitted with an unwoven mat 2 impregnated with resin selected from thermo-plastic resin, for example, acrylic, SBR, NBR, PVA and the like with one side thereof covered with thermo-plastic resin 4 foamed via the thermal expansion of a thermal expansion type micro capsule 4, for example, the foamed resin layer of SBR resin. In addition, the constitutional fabric surface of the unwoven mat 2 having a foamed thermo-plastic resin layer 5 on one side is covered with thermo-plastic resin 6 such as SBR or covered with the mixed resin binder of thermo-setting resin. According to the aforesaid construc tion, it is possible to avoid damaging the surface of a fry pan, pot and the like processed with silver stone and Teflon(R) low in an allowance for damage, and to remove a persistent stain on the aforesaid surface.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of a household scrubbing brush used for tableware, cooking utensils, kitchen equipment, and the like.

(Prior technology) Conventionally, household scrubbers have been made of tortoiseshell scrubbers made of juro hair, metal scrubbers, soft urethane foam sponges, cellulose sponges, white aluminum oxide, non-woven fabric scrubbers containing abrasives such as garnet, and emery silica. ing.

(Problem to be solved by the invention) Recently, many cooking utensils such as silverstone and Teflon-treated frying pans and pots are being used, which are easy to get dirty or scratched. ,
Metal scrubbers and non-woven scrubbers containing abrasives remove dirt very well, but they have drawbacks such as scratches on the silverstone and Teflon coated layers, and furthermore, premature cracking of the coated layers due to surface abrasion. Furthermore, although soft urethane foam sponge and cellulose sponge do not cause scratches, they have drawbacks such as difficulty in removing stuck dirt.

(Means for Solving the Problems) In order to solve the above-mentioned drawbacks, the present invention includes a foamed thermoplastic resin adhesive layer foamed by expansion of thermally expandable microcapsules on one side of a nonwoven fabric mat made of synthetic fibers. Furthermore, the problem has been solved by providing a structure in which the nonwoven fabric mat having the foamed thermoplastic resin adhesive layer is impregnated and coated with a thermosetting resin.

(Function) Since the soft bundler of the present invention does not use an abrasive material, it does not damage silverstone, Teflon-treated surfaces, etc. even during cleaning and rubbing operations.

In addition, due to the cushioning properties of the foamed resin and the hardness and durability of the thermosetting resin covering the resin particles, sufficient cleaning power can be obtained that is suitable for hardened and uneven soiled surfaces. The blending amount of thermally expandable microcapsules per thermoplastic resin is preferably 20 to 50 parts (parts by weight) per 100 parts (parts by weight) of the thermoplastic resin; if it exceeds 50 parts, the strength of the bundle itself will decrease, resulting in poor durability. If the amount is less than 20 parts, the foamability will be insufficient and the texture will be lost, resulting in a lack of design.

In addition, the thermoplastic resin foamed by the expansion of thermally expandable microcapsules has a large number of closed cells, so it has an uneven appearance and a very flexible texture, giving it a design and texture not found in conventional non-woven scrubbers. Become something.

(Example) Hereinafter, one example of the present invention will be described based on the drawings. Nylon fiber 14d x 38m/m, 100% fiber fabric weight 130g/m random or cross web, polyvinyl alcohol resin 40 parts, melamine resin 6
dpu = 65% [(mold weight after impregnation - weight before impregnation) 10 weight before impregnation x 1001 (hereinafter referred to as dpu) with a water-based resin consisting of 0 parts, and 140g on both sides with an emulsion of 100% SBR resin. Spray processed by /i 243
A nonwoven mat of g/m was obtained. Then SBR resin 100
parts (parts by weight) to 30 parts of thermally expandable microcapsules (
After spraying 170 g/rrr on one side with a water-based resin consisting of (parts by weight) and drying at 100°C
Heating at 0°C for 5 minutes caused foaming and hardening of 5BIl[t as the thermally expandable microcapsules expanded, resulting in a fabric weight of 41.
A nonwoven mat of 3 g/m was obtained. Next, the nonwoven fabric mat was impregnated with DPU=50% with a water-based resin consisting of 100 parts of 5BR and 20 parts of melamine resin to obtain a soft bundle of 620 g/rrf. As shown in FIGS. 1 and 2, the soft bundler of the present invention obtained in the above example is a synthetic fiber example (
11 For example, nylon, polyester, polypropylene,
A thermoplastic resin such as acrylic, SB is added to a web made of vinylidene chloride, acrylic, etc., either singly or in combination.
On one side of a non-woven fabric mat (2) impregnated and sprayed with a resin selected from R, NBR, PVA, etc., thermally expandable microcapsules containing low boiling point hydrocarbons are made of resin such as vinylidene chloride or acrylic as a shell wall. A thermoplastic resin (4) foamed by thermal expansion of (3) is formed, for example, a foamed resin layer of SBR resin, and the constituent fiber surface of the nonwoven fabric mat has a foamed thermoplastic resin layer (5) on one side of the thermoplastic resin. (6) For example, it is constructed by binding a resin such as SBR, NBR, acrylic ester, EVA, etc. or the above resin as a main body and coating it with a mixed resin binder of a thermosetting resin such as melamine, epoxy, phenol, etc. In addition, the ratio of the thermosetting resin to be blended as necessary for coating the nonwoven fabric mat described in Section 2 is determined as appropriate depending on the use. In addition, for objects to be cleaned that are difficult to remove dirt from, they can be coated with a thermosetting resin or a thermosetting resin alone.

(Comparative Example 1) One side of the above non-woven fabric mat was sprayed with 170 gems of a solvent-based resin consisting of 80 parts of phenol resin, 20 parts of epoxy resin, 100 parts of garnet sand, and 100 parts of aluminum hydroxide, and a non-woven fabric scrubber with a basis weight of 413 g/m was applied. Obtained.

(Comparative Example 2) One side of the above nonwoven fabric mat was sprayed with a solvent-based resin consisting of 80 parts of phenol resin and 20 parts of epoxy resin at 170 g/m to obtain a nonwoven fabric scrubber with a basis weight of 413 g/rrr.

(Comparative Example 3) One side of the above nonwoven fabric mat was sprayed with an emulsion consisting of 100 parts of SBR at 170 g/m to give 413 g.
