ンウォッシュと称される方法である。Conventional Technology and Problems Jeans are washed as one of the essential manufacturing processes for the purpose of bleaching them and adjusting their texture. The basic method of washing these days is a method called stone washing, in which stones are washed in the same bath as the stones.

７〜１．３程度の範囲につくられたものである。However, natural pumice has the inherent drawback that it is extremely abrasive and has poor durability. For this reason, artificially created inorganic foams are increasingly being used these days. This inorganic foam is mainly made of glassy mineral powder such as shirasu, anti-flinder, acid clay, weathered granite, nacre, tuff, etc., and a blowing agent such as dolomite, SiC, etc., and soda ash, sodium nitrate, etc. A mixture of barium carbonate, glass powder, and other melting aids is added to the
By heating and firing at approximately 250°C, the bulk specific gravity is reduced to 0.
It was made in the range of about 7 to 1.3.

た。However, even in the case of washer balls made of artificially created inorganic foam, they are far superior to natural pumice in terms of abrasion strength, and improvements are still required. In terms of decolorizing performance, it was not always possible to obtain sufficient satisfaction.

うにしたものである。Means for Solving the Problems For the above-mentioned purpose, the present invention mixes inorganic hard particles, which are harder than the matrix of the partition walls, into the cell-constituting partition walls of an inorganic foam, and the protrusion of the hard particles violently roughens the surface of the jeans. The washer ball can be rubbed and quickly decolorized, and at the same time, the presence of the hard particles significantly improves the wear resistance of the washer ball itself.

The object of the present invention is to provide an artificial washer ball for stone washing, which is characterized in that inorganic hard particles are dispersed and mixed therein.

ス部分の硬度がこれに相当するものである。In this invention, the hard particles mixed into the partition walls are selected from particles that are relatively harder than the matrix constituent material of the partition walls, such as porcelain or insulators. Cerbenes, feldspar, quartz,
Hard particles having a Mohs hardness of 5 or more, particularly about 6 to 7, such as chinastone and low stone, are used alone or in a mixed state of two or more. By the way, the Mohs hardness of natural pumice is about 3. In addition, the value of conventional artificial inorganic foams is approximately 4 to 5.
This corresponds to the hardness of the matrix portion of the partition wall of the inorganic foam of the present invention.

る混入量は、概ね２０〜３０重量部の範囲である。The amount of the inorganic hard particles mixed is preferably about 10 to 35 parts by weight based on 100 parts by weight of the matrix material powder. If the amount exceeds the lower limit and is too small, it will not be possible to provide the desired high level of abrasion resistance and decolorizing performance. On the other hand, when the upper limit is exceeded and too much is mixed in, the abrasion force becomes too strong and there is a risk of damaging the surface structure of the jeans. The most suitable amount is approximately 20 to 30 parts by weight.

When coarse particles exceeding wn are used, they tend to fall off from the partition walls, making it difficult to maintain stable scrubbing performance and decolorizing performance, and also cause the same drawbacks as when they are mixed in too much. do.

With the inorganic foam mixed with relatively coarse particles of 8MR, it is possible to obtain a bleached state with uneven linear bleaching, that is, a shaded pattern. In this way, the decolorization pattern can be varied by selecting the particle size of the hard particles mixed into the foam, and therefore it is possible to use a combination of multiple types of foam using hard particles with different particle sizes. It is possible to freely express the bleaching pattern of your choice by selecting only a foam using fine particles or coarse particles.

かできる。Effects of the Invention As described above, the present invention is an inorganic foam that can be manufactured artificially and has excellent mass productivity, and can be manufactured and provided at a relatively low cost. Since inorganic hard particles, which are harder than the partition wall, are dispersed in the part, the presence of the hard particles increases the abrasion strength, increases the service life, and reduces the cost of consumables for stone washing, which is an economical benefit. At the same time, the hard particles protrude from the partition walls due to abrasion of the partition walls, and are rubbed directly onto the surface of the jeans, so it exhibits excellent decoloring performance and can achieve the required color removal in a short time. This can shorten the time required for the stonewashing process. Furthermore, as mentioned above, the tone of decolorization can be changed by selecting the particle size of the hard particles to be mixed in, making it possible to easily meet the needs for expressing a wide variety of decolorization patterns.

く攪拌混合した。On the other hand, 60 g of porcelain Cervene as hard particles was mixed with 109 g of water to make it wet, and then added to 140 g of the matrix material powder obtained above and mixed with thorough stirring.
然るところ、湿った硬質粒子の表面に上記マトリックス
材料粉末が均一に付着コーティングされた含水率７％の
混合粉末を得ることができた。However, it was possible to obtain a mixed powder with a water content of 7% in which the matrix material powder was uniformly adhered and coated on the surface of the wet hard particles.
そこで、この混合粉末８ｇを直径２３Ｍの円筒形の金型
に充填し、１５０に９ｆ／ｃｄの圧力で加圧成形した。Therefore, 8 g of this mixed powder was filled into a cylindrical mold with a diameter of 23M, and pressure molded at a pressure of 150 mm and 9 f/cd.
こ＼に上下の加圧金型は半径６０ｒｒｍの皿型のものを
用い、中高円盤状の成形体を得るものとした。In this case, the upper and lower pressing molds were dish-shaped with a radius of 60 rrm to obtain a medium-high disk-shaped molded product.
次いで、この成形体を乾燥後、電気炉の離型剤を塗布し

ているものであることを確認し得た。As shown in the figure, the washer ball according to the present invention (Example 1.2) is significantly more effective than the conventional one made from pumice (Comparative Example 2), and is made from an inorganic foam that does not contain inorganic hard particles. It was confirmed that the wear loss was relatively small and the wear strength was much better than that of the comparative example.
