Claims (8)

A cleaning sheet comprising at least one long fiber bundle in which long fibers oriented substantially in one direction are gathered on at least one surface of a base sheet,
The long fiber bundle is formed by bonding the long fibers to each other in a direction intersecting with the orientation direction of the long fibers by a fiber bonding portion extending linearly. A cleaning sheet bonded via a sheet bonding portion, wherein all of the fiber bonding portions or at least a part of the fiber bonding portions are not bonded to a base sheet.   The cleaning sheet according to claim 1, wherein the plurality of sheet joining portions are intermittently disposed in a direction intersecting with the orientation direction of the long fibers.   The size of each said sheet | seat junction part is a sheet | seat for cleaning of Claim 1 or 2 long in the orientation direction of the said long fiber.   The said sheet | seat junction part is a sheet | seat for cleaning in any one of Claims 1-3 distribute | arranged on the said fiber junction part.   The said fiber joined part is formed in the shape of one continuous straight line, or two parallel discontinuous line | wires by which the discontinuous part was alternately arrange | positioned. Cleaning sheet.   The cleaning sheet according to claim 1, wherein the fiber bonded portion is bonded to the sheet bonded portion, and at least a part of the fiber bonded portion is not bonded to the base sheet. It is a manufacturing method of the cleaning sheet in any one of Claims 1-6,
The union of the long fibers oriented in one direction is unwound, widened to a predetermined width, and the long fibers are joined and integrated by the fiber joining portion extending in a direction intersecting the orientation direction of the long fibers. A long fiber bundle forming step of forming a long fiber bundle;
A long fiber bundle supplying step of supplying the at least one surface of the strip-shaped base sheet continuous in the same direction as the orientation direction of the long fibers;
A laminate forming step of forming a laminate by joining the long fiber bundle and the belt-like base sheet through the sheet joining portion;
A cleaning sheet manufacturing method comprising at least a cleaning sheet forming step of cutting the laminate to a required length to obtain individual cleaning sheets. A long fiber bundle cutting step of cutting the integrated long fiber bundle into a required length;
The long fiber bundle was cut to a required length, claim and a supplying continuous fiber bundle supplying step on at least one surface of the strip of the base sheet which is continuous in the orientation direction in the same direction of the long fibers A method for producing the cleaning sheet according to claim 7.
