Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a non-woven fabric base sheet and a non-woven fabric bundle using the non-woven fabric base sheet, which are particularly suitable for cleaning toilets and bathrooms using a chemical detergent.

[0002]

[Prior art]

 Conventionally, as a bundle for a toilet or bathroom, a sponge bundle made of urethane foam or the like, and a nonwoven fabric bundle made of vinylidene chloride fiber or nylon fiber having chemical resistance are generally used.

Further, as a non-woven fabric bundle for ordinary cleaning tools, a fiber having a difficulty in adhering fibers (olefin fiber) is entangled by a needle punching process or a fiber having a heat-fusible fiber is melted by heat. The one worn is used.

[0004]

[Problems to be solved by the device]

However, a non-woven fabric bundle made of vinylidene chloride fiber produces chlorine gas when incinerated, and a non-woven fabric bundle made of nylon fiber not only has poor drainage, but also produces cyan gas when burned at a high temperature. Therefore, neither is suitable as a disposable product.

In addition, among the usual non-woven fabric bundles for cleaning tools, the former has excellent chemical resistance, but the density is increased by needle punching and it is inferior in bulkiness, so not only is it difficult to grab by hand and work, Drainage is difficult, and the latter has a certain amount of bulkiness, but it is inferior in flexibility, so it is difficult to follow hard curved surfaces such as toilet bowls and bathtubs made of porcelain, synthetic resin, etc. It was difficult to clean efficiently, and neither was suitable as a bundle for toilets or bathrooms.

By the way, as the waste of disposable products has become a problem in recent years, olefinic fibers that do not generate a bad odor upon incineration and have chemical resistance have been attracting attention. By using these fibers, bulkiness and flexibility are obtained. The fact is that a flexible nonwoven fabric bundle has not been obtained.

The present invention solves the above-mentioned problems of the prior art, and has chemical resistance, bulkiness, flexibility, and drainability, and does not generate a bad odor when incinerated, such as a toilet or bath using a chemical detergent. It is an object of the present invention to provide a nonwoven fabric base sheet for a bundle and a bundle that are optimal for cleaning such items.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems of the prior art, the present invention provides a solvent having alkali resistance and acid resistance, and an olefin fiber surface portion (a surface layer portion from the fiber surface to the inside of the fiber) having alkali resistance and acid resistance. The binder resin is fixed with an anchoring effect, and the strongly fixed binder resin covers most of the fiber surfaces of the constituent fibers and fixes the fiber entanglement.

[0010] The non-woven fabric bundle base sheet thus configured can exhibit excellent effects on a chemical detergent because the constituent fibers and the binder resin have alkali resistance and acid resistance. In addition, since the surface of most of the constituent fibers is covered with the binder resin having the desired elasticity and the fiber entanglement is fixed, it has bulkiness, flexibility, drainage resistance, and durability. It has an excellent and moderate frictional force and can exhibit an excellent cleaning effect.

[0011]
