It is known as an excellent wiper base cloth because it has features such as low dust generation because it is composed of continuous fibers and excellent oil retention because it is made of hydrophobic resin. There is no water absorption as it is as a raw material, but hydrophilic treatment is required to impart water absorption,
In that case, there are drawbacks such as the problem of elution of the hydrophilic treatment agent and the high cost.

トラブルが発生しない。SUMMARY OF THE INVENTION The present invention makes it possible to produce a high-performance wiper base fabric which complements each other's disadvantages at low cost by combining the advantages of both. That is, high water absorption and reduction of raw material costs are realized by laminating pulp sheets, and excellent wiping performance, high wet strength, and low dust generation are realized by laminating a non-woven melt-blown cloth. Further, since the heat bonding is performed by the heat embossing roll, no trouble occurs due to elution of the binder or the like during the wiping operation.

The component composition ratio of the wiper base fabric of the present invention is 5 to 95% by weight of a pulp sheet and 95 to 5% by weight of a nonwoven sheet.
Preferably, it has a three-layer structure of nonwoven sheet / pulp sheet / nonwoven sheet, and is composed of 40 to 90% by weight of pulp sheet and 60 to 10% by weight of nonwoven sheet. The heat bonding is performed by a heat embossing roll, and the fused portion is 2 to 50%, preferably 5 to 30% with respect to the sheet surface area.

なる。[0007] Meltblown nonwoven for use in wiper base fabric of the present invention is directed to a basis weight 3~100g / m 2. As the raw material, various resins such as polypropylene and polyester can be used, but polypropylene which is inexpensive and has a relatively low melting point is preferable. Depending on the purpose, those subjected to a hydrophilic treatment can also be used. The bonding method is a simple and low-cost heat bonding using a heat embossing roll that does not use a binder or the like. The fused portion by thermal bonding is 2 to 50%, preferably 5 to 30%, based on the sheet surface area.
If the fused portion is less than 5%, sufficient adhesive strength cannot be obtained,
If it is more than 30%, there is a problem that the fused portion inhibits the water absorption performance.

は大きい。As is clear from the table, the wiper base fabric of the present invention has a lower wet strength than the hydrophilically treated PP melt blown wiper which is said to have excellent performance (but also has a difference in basis weight). ), There is no difference in water retention and oil retention. The wiping rate is also significantly higher than that of the pulp wiper, indicating a value close to that of the PP melt blown wiper. The dust generation rate is significantly lower than that of pulp wipers, and the treatment agent is not eluted unlike the hydrophilically treated PP melt blown wipers. Such a high-performance wiper base fabric can be manufactured at low cost, and the product has great industrial significance.
