Abstract: A spinning die for melt-blowing has plastic passages, a hot air passage, and an opening surface, in which discharge ports and blowing ports open. Adjacent and closest two of the discharge ports are first and second proximate discharge ports. One of the blowing ports corresponding to the first proximate discharge port is a first proximate blowing port, and one of the blowing ports corresponding to the second proximate discharge port is a second proximate blowing port. The first proximate blowing port includes a guide portion that projects away from the center of the first proximate discharge port. The guide portion is formed such that, as the distance from the opening surface increases, the hot air flow guided by the guide portion flows to be separated away from the hot air flow blown onto the molten plastic discharged from the second proximate discharge port.

Abstract: A wiping cloth made of nonwoven fabric of which water-absorbing property is superior and deteriorates less with age is provided. This wiping cloth made of nonwoven fabric is obtained using specific splittable conjugate fibers. The splittable conjugate fibers are formed by sticking a polyester polymer component A containing polyoxyalkyleneglycol of 2000 to 20000 in mass average molecular weight and a polyolefin polymer component B not compatible with said polymer component A together. Fibers A composed of the polymer component A and fibers B composed of the polymer component B are formed by exfoliating the sticking of the splittable conjugate fibers. Plasma treatment is applied to exfoliated faces of the fibers A and the fibers B. The water-absorbing property is largely improved due to synergism of polyoxyalkyleneglycol and plasma treatment applied to the exfoliated faces of the fibers A and B.
