According to the present invention, it is possible to obtain a non-woven fabric that is excellent in bulkiness, flexibility, and feeling, in which less fibers drop out even in the case wherein the non-woven fabric is used for an application such as clothing items and a wiping cloth in which a surface of a non-woven fabric is rubbed, that is, excellent in a lint-free property. A mixed continuous fiber non-woven fabric in accordance with the present invention is characterized by comprising a split continuous fiber and a crimped continuous fiber, and is preferably characterized in that a total amount of the crimped continuous fiber is in the range of 10 to 90% by weight (where a total weight of a split continuous fiber and a crimped continuous fiber is 100% by weight).
A mixed continuous fiber non-woven fabric comprising a split continuous fiber and a crimped continuous fiber that does not have a split property.
A method for producing a mixed continuous fiber non-woven fabric, comprising the steps of laminating a split continuous fiber non-woven fabric and a crimped continuous fiber non-woven fabric, applying a high pressure liquid flow to the laminate, and mixing a split continuous fiber and a crimped continuous fiber.
A method for producing a mixed continuous fiber non-woven fabric, comprising the steps of laminating a splittable conjugated continuous fiber non-woven fabric and a crimped continuous fiber non-woven fabric, applying a high pressure liquid flow to the laminate, splitting a splittable conjugated continuous fiber, and mixing a split continuous fiber and a crimped continuous fiber.
A method for producing a non-woven fabric, comprising the steps of discharging a splittable conjugated continuous fiber and a crimped continuous fiber from a spinneret provided with a spinning nozzle for a mixed fiber, cooling a mixed continuous fiber made of the splittable conjugated continuous fiber and the crimped continuous fiber to which a spinning has been carried out by a cooling fluid, applying a tension to the mixed continuous fiber by a fluid to thin the mixed continuous fiber, and depositing the mixed continuous fibers on a collection belt.
