The present invention relates to an improved abrasive scrubber characterized by strengthening the strength of the villi fiber piles formed on both sides by brushing thick base tissues such as acrylic yarn or other synthetic fiber yarns, and spraying abrasive powder.

Conventional polishing scrubbers are applied to acrylic yarns or other synthetic fiber nonwoven substrates by spraying a phenol resin solution dissolved in alcohol, spraying the abrasive stone powder, and then heating and drying at about 140 ° C. for 1-2 times. By attaching the abrasive stone powder on the fiber pile and surrounding it with a phenol resin film, the strength of the fiber pile was enhanced.

However, although the abrasive scrubber has a high strength of the fiber pile and firmly adheres to the abrasive stone powder, it is easily torn or water-wrapped due to the non-woven nature of the nonwoven fabric substrate. A weak durability is pointed out.

The present invention is to provide a polishing scrubber that improves the above-mentioned shortcomings of the polishing scrubber and a method of manufacturing the same, by squeezing both sides of the base tissue by squeezing a thick base tissue such as acrylic fiber or other synthetic fiber yarn in the first step. Strengthen the strength of the chorionic fiber pile and myocardial tissue by forming a thick and dense chorionic layer on both sides of the myocardial tissue and attaching the abrasive stone to the fiber pile of the chorionic layer on both sides of the myocardial tissue according to the method known in the second step. It does not distort and tears even when crumpled in water, and it greatly improves durability.

Hereinafter, the present invention will be described in detail with reference to Examples.

The first step is the composition of the base structure, and the base structure 1 is made of acrylic yarn or other synthetic fiber yarn.

Choosing tissues that are not limited to woven tissues but with relatively low folds is recommended, and weaving yarns are usually recommended, in which weft yarns are tied to chain knitting.

When the base tissue 1 is completed, both surfaces are brushed to form dense chorionic layers 12 and 12 'on both sides of the myocardial base tissue 11.

In the second step, the abrasive stone powder 112 is attached and fixed to the villi layers 12 and 12 'on both sides of the myocardial base tissue 11, and the flexible material is mixed on the fiber pile of the villi layer. Abrasive stone powder is fixed on both sides of the reinforced myocardial tissue 211 formed by enclosing a phenol resin film, and the abrasive fiber piles 222 and 222 ′ having strength are configured.

To explain this in more detail, the phenolic resin dissolved in alcohol becomes a slightly hardened product when the fiber is fixed to the fiber pile. Atomizing spray coating is applied to the villi layer 12 (12 ') on both sides of the myocardial tissue (11), and the fine abrasive stone powder (112) is sprayed and applied to the villi of the container (111). Then, the abrasive polishing powder mixture mixture 114 containing the pigment and the abrasive stone mixed with the phenol resin solution dissolved in alcohol was successively continued with the first polishing stone powder attaching process which is heated and dried at about 10 minutes in the heating furnace 113 at about 120 ° C. After sufficiently penetrating into the inner layer 12 (12 ') (including the deep base tissue), the filtrate was squeezed out with the press roller 115, and the heating furnace 116 at a temperature of 140 ° C. to 160 ° C. was used for 30 minutes. After the second abrasive stone powder is exaggerated and dried, it is cut to an appropriate size, and the abrasive stone powder is fixed to the villi layer 12 (12 ') on both sides of the strength-strengthened myocardial tissue 211, and the phenol resin is coated to give strength. A desired improved abrasive scrubber composed of the viscous-shaped abrasive fiber piles 222 and 222 'is reinforced.

As the polishing scrubber obtained as above has a strong strength of myocardial tissue, the circular shape is not broken even when wrinkled in the water as in the conventional nonwoven scrubber, and the tensile strength is enhanced and not torn. It has the effect of greatly improving the durability.
