Demonstrate. Furthermore, when the thick fibers are opened with a card machine together with the easily split fibers, the easily split fibers are sufficiently split only by passing through the card machine due to the rigidity of the thick fibers. Also has excellent cleanliness.

It is necessary to mix 0% by weight or more. More preferably 4
It is 0% by weight or more. On the other hand, when the amount of thick fibers exceeds 90% by weight, the amount of easily split fibers becomes too small and the cleanliness of the oil film and the like deteriorates. Therefore, the amount of thick fibers needs to be 90% by weight or less. It is more preferably 70% by weight or less.

っても良い。The easily splittable fiber of the present invention is easily split by mechanical impact, and the fineness of the splittable fiber is 0.01 to 0.0.
It is a fiber that gives a fiber of about 5 denier. As the easily split fibers, polyamide resin and polyester resin, polyamide resin and polyolefin resin, polyamide resin and polyacrylonitrile polymer resin, polyester resin and polyolefin resin, polyester resin and polyacrylonitrile resin, polyolefin resin and poly A combination of acrylonitrile-based polymer resins can be exemplified,
It is not limited to the easily split fibers composed of these two kinds of resins, but may be easily split fibers composed of three or more kinds of resins.

有するため、より油膜などの清浄性に優れている。The resin components may be arranged in any manner. For example, chrysanthemum-shaped fibers having a cross-sectional shape in which one component is radially arranged between the other components, or different components are alternately laminated in layers. There is a bimetal type fiber. Since the ultrafine fibers obtained from these easily split fibers have a sharp cross-sectional shape portion, they are more excellent in cleanability such as an oil film.

On the contrary, if it exceeds 80% by weight, the cleanliness, dust absorption and Since the effect of splittability cannot be obtained, the amount of easily splittable fiber must be 10 to 80% by weight. More preferably, it is 30 to 60% by weight.

ることができる。Furthermore, in addition to the thick fibers and the easily split fibers, heat fusible fibers are mixed to obtain a fiber web, and the heat fusible fibers are fused under no pressure to bond them in a bulky state. Therefore, it is possible to obtain a nonwoven fabric wiper that does not adversely affect the dust absorption.

It may be fiber. In the latter case, if only one resin component is fused, strength can be obtained by the other resin component, so that it can be suitably used. The melting point of the fusible resin component of the heat-fusible fiber is preferably 10 ° C. or more lower than the melting point of the constituent component of the ultrafine fiber so as not to fuse the ultrafine fibers.

維による空隙を保持している。The above-mentioned thick fibers, easily split fibers or, if necessary, heat-fusible fibers are opened by a card machine to obtain a fiber web. When the fiber is opened by this card machine, the easily split fibers are mixed with the thick fibers so that they can be easily and sufficiently split, and the ultrafine fibers are entangled with the thick fibers in a point manner. It is strong and holds voids due to thick fibers.

繊維ウエブが得られる。When forming a fibrous web, the orientation of the fibrous web is not particularly limited. For example, if the fibrous web is oriented so that the fibers cross each other by a cross layer, the fibrous web has uniform strength in all directions, If it is oriented in one direction,
A fiber web having excellent strength in the orientation direction and having excellent strength can be obtained by laminating a crossed fiber web and a unidirectional fiber web.

いが、５〜２００本／g/m2で行なえば、繊維ウエブの嵩
高な状態を維持し、吸塵性も低下しない。When the nonwoven web wiper of the present invention is entangled with the fiber web by the needle punching method, the easily splittable fibers have already been sufficiently divided in the state of the fiber web, but the fiber is further divided by the needle punching method and further entangled. As a result, a non-woven fabric wiper excellent in cleanliness and strength such as an oil film and strength can be obtained. The needle density is not particularly limited, but if the needle density is 5 to 200 needles / g / m 2 , the bulkiness of the fiber web is maintained and the dust absorption property is not deteriorated.

清浄性に優れた不織布ワイパーが得られる。Further, when the bonding is carried out by the spray method, since the adhesive is bonded mainly at the intersections of the fibers, the ultrafine fibers are entangled in the thick fibers in a point manner and bonded in the fiber web state in which the voids of the thick fibers are held, It is possible to obtain a non-woven wiper having excellent cleanliness and dust absorption by thick fibers and cleanliness such as oil film by ultrafine fibers.

パーが得られる。When the fiber webs are bonded by the thermal bonding method using the heat-fusible fibers, the portion where the heat-fusible fibers are in contact with the thick fibers or the ultrafine fibers is similar to the case of bonding by the spray method. Since the fibers are bonded only by themselves, a nonwoven fabric wiper that maintains the state of the fiber web and is excellent in cleanability and dust absorption can be obtained.

A fiber web was obtained in which ultrafine fibers obtained by splitting easily split fibers were entangled with thick fibers. An acrylic emulsion having a solid content of 15 g / m 2 was adhered to this fiber web by a spray method, and then the fibers were bonded by heat treatment at 150 ° C. for 3 minutes to obtain a nonwoven fabric wiper of the present invention. Table 1 also shows the basis weight, thickness, and apparent density of this nonwoven fabric wiper.

0% by weight, 60% by weight of thick fiber, and 10% by weight of core-sheath type composite fiber composed of high melting point polyester / low melting point polyester resin (fineness 4 denier, fiber length 51 mm, melting point of low melting point polyester: 110 ° C.) The fibers thus obtained were opened with a card machine and then oriented so as to intersect with each other by a cross layer to obtain a fiber web in which ultrafine fibers obtained by dividing easily split fibers were entangled with thick fibers. This fiber web is heated to a temperature of 15
Heat treatment was performed at 0 ° C. for 3 minutes to obtain the nonwoven fabric wiper of the present invention bonded by the heat-fusible fiber. Table 1 also shows the basis weight, thickness, and apparent density of this nonwoven fabric wiper.

A load of 50 g / cm 2 is applied to the nonwoven fabric wipers of Examples 1 to 5 and Comparative Examples 1 to 3 to wipe them for 12.5 cm.
Then, wiping off the carbon black on another OHP film having the same carbon black layer is repeated until the carbon black cannot be wiped off by the non-woven wiper, and the number of carbon blacks on the OHP film is brought to that state. Find out if it can be wiped off. The results are shown in Table 1.
