An aspirating jet piddler that has no moving parts and operates to achieve a soft laydown with reduced tangling.

Air jet piddling

A sheath-core polyester fiber where the sheath includes an antimicrobial agent and the sheath comprises less than thirty percent of the total cross-sectional area of the fiber. The antimicrobial agent is selected such that the relative viscosity of the fiber lies above a defined spinnability limit, so that spinning is possible. With no loss in antimicrobial efficacy, the fiber of the present invention may be slickened with a siliconized finish in order to reduce fiber friction, thus giving the fiber a silky feel.

Sheath-core polyester fiber including an antimicrobial agent

An aspirating jet piddler that has no moving parts and operates by swirling a textile tow line pneumatically to achieve a soft laydown with reduced tangling.

Improved polyester fibers, filling materials and filled articles are provided by fibers of helical configuration, high void content and low friction.

Polyester fiber

Synthetic fibers that have a round cross-section and three round longitudinal voids.

Synthetic fiber cross-section

Bicomponent polyester fibers that have 'spiral crimp' on account of a difference in chain-branched content of the polyester polymers of the components. Such bicomponent fibers are preferably hollow and may be slickened, such as for use as filling material for pillows or other filled articles.

Bicomponent polyester fibers

Pillows and other filled articles are filled with bicomponent polyester fibers that have 'spiral crimp' on account of a difference in chain-branched content of the polyester polymers of the components. Such bicomponent fibers are preferably novel 'spiral crimp' bicomponent fibers that are hollow and/or are slickened.
