An air jet for producing a filter plug for cigarette comprising an imparting portion for propelling force to a tow-like fiber bundle and a beak portion, wherein said imparting portion is constructed by a trumpet (21) having a converged tip end region, a trumpet holder (23) coaxially and encirclingly assembled on the trumpet (21) so that a primary air chamber (26a) is formed between the bodies of the trumpet and the trumpet holder, and an annular slit (29) communicated with the primary air chamber (26a) is also formed between the tip end regions of the trumpet (21) and the trumpet holder (23). An inner tube (22) is disposed coaxially in front of the assembly of the trumpet (21) and the trumpet holder (23), whereby a fiber path through which the tow-like fiber bundle is fed to a tongue of a filter plug machine is formed through the air jet along the axis thereof; the fiber bundle being accelerated by a propelling force imparted by compressed air ejected from the annular slit (29) to the fiber path. An inner tube holder (25) is coaxially and encirclingly assembled on the inner tube (22) to form the beak portion (30) so that a secondary air chamber (26b) is formed between the bodies of the inner tube (22) and the inner tube holder (25), and a means for opening and interlacing fibers in the fiber bundle is provided in the inner tube (22).

A stick absorber for the oral cavity comprising a bundle of fibers, the periphery of said bundle of fibers being wrapped with a water-permeable tape, and said tape being adhered at its joint with a binder. The stick absorber has high water absorbability and spacing effects, and does not release its constituent fibers into the oral cavity.
