However, there are some oily stains that cannot be wiped off with a rag, tissue, etc., and in this case, the detergent had to be used in combination to remove the stains. Therefore, you don't have to bother to include detergent in the rag and tissue.
A wiper is known in which a rag, a tissue, and the like are preliminarily mixed with a detergent, a chemical solution, and the like. However, since these wipes and tissues do not have strength and have no shape retention property in a wet state, they are difficult to wipe and are inferior in wiping property.

However, even in this wiping cloth, as in the case of the conventional cloth and tissue, it has no strength particularly in a wet state and has no shape retention, so that it is difficult to wipe and inferior in wiping property.

れを払拭しやすい。The non-woven fabric for wiping of the present invention has an ultrafine fiber layer mainly composed of fibers having a fineness of 0.5 denier or less, so that even fine dirt can be wiped off, and fibers having a fineness of 0.5 denier or less are lipophilic. If it is a synthetic fiber, it is easier to wipe off oily stains.

する。Since the non-woven fabric for wiping of the present invention has a hydrophilic fiber layer mainly composed of hydrophilic fibers, it is possible to wipe and retain aqueous stains by the hydrophilic fiber layer. It should be noted that the chemical liquid or the like can be held in a wet state, and the chemical liquid or the like is exuded to the ultrafine fiber layer by the pressure of the hand at the time of wiping, so that the wiping property by the ultrafine fiber layer is dramatically improved.

により払拭された油性の汚れを保持する。Since the fusible fiber layer of the present invention is located between the ultrafine fiber layer and the hydrophilic fiber layer and the heat fusible fibers are fused, the wiping non-woven fabric as a whole is given strength and heat fusion. Since the elastic fiber does not swell or deform even in a wet state, shape retention in a wet state is imparted. Therefore, the non-woven fabric for wiping of the present invention is easy to wipe and has excellent wiping property. Further, since the heat fusion layer of the present invention is not mixed with the ultrafine fibers but is a layer, the wiping property of the ultrafine fibers is not deteriorated. Since the heat-fusible fiber is generally lipophilic, it retains oily stains wiped off by the ultrafine fiber layer or hydrophilic fiber layer.

標準時と同様にして縦と横の引張強度を測定する。(Tensile strength test when wet) The non-woven fabrics for wipers of Examples 1 and 2 and Comparative Example, which were cut into 5 × 20 cm, were wetted and squeezed to have a water content of 1.5 times their own weight.
The longitudinal and transverse tensile strengths are measured in the same manner as the standard time.

【発明の効果】本発明のワイピング用不織布は極細繊維
層があるため、微細な汚れを払拭することができる。Since the non-woven fabric for wiping of the present invention has the ultrafine fiber layer, fine dirt can be wiped off.
【００４２】本発明のワイピング用不織布は親水性繊維
層があるため、親水性繊維層によって水性の汚れを払
拭、保持することができる。しかも、湿潤状態では薬液
などを保持することができ、払拭する際の手の圧力によ
って極細繊維層に薬液などを滲み出させ、払拭性を飛躍
的に向上させる。Since the non-woven fabric for wiping of the present invention has the hydrophilic fiber layer, it is possible to wipe and retain water-based stains by the hydrophilic fiber layer. In addition, it is possible to retain the chemical liquid or the like in a wet state, and the chemical liquid or the like is exuded to the ultrafine fiber layer by the pressure of the hand when wiping it, and the wiping property is dramatically improved.
【００４３】本発明の融着繊維層はワイピング用不織布
全体に強度を与え、乾燥状態はもちろんのこと、湿潤状
態での保形性を付与する。そのため、どのような状態に
あっても拭きやすく、払拭性に優れたワイピング用不織
布である。The fusible fiber layer of the present invention imparts strength to the entire non-woven fabric for wiping and imparts shape retention not only in the dry state but also in the wet state. Therefore, it is a non-woven fabric for wiping that is easy to wipe in any state and has excellent wiping properties.
【００４４】また、本発明の熱融着層は極細繊維層と混
合されているのではなく、実質的に層となっているた
め、極細繊維層の払拭性を低下させるということがな
い。Since the heat-sealing layer of the present invention is not mixed with the ultrafine fiber layer but is substantially a layer, the wiping property of the ultrafine fiber layer is not deteriorated.
【００４５】更に、融着繊維層は極細繊維層或いは親水
性繊維層により払拭された油性の汚れを保持する。Further, the fusion-bonded fiber layer holds oily dirt wiped by the ultrafine fiber layer or the hydrophilic fiber layer.
