Bicomponent fibers with high wicking rate

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

An apparatus for radially quenching melt spun filaments features a quenching chamber having a foraminous distribution cylinder between the filaments and the gas supply chamber with areas of porosity that increases, from a first low value at a location immediately below the spinneret, through a larger value at lower location, and then decreases toward the exit of the quench chamber.

Apparatus for quenching melt spun filaments

Fine denier polyester fibers are obtainable from polymer of low molecular weight to have improved uniformity and excellent mechanical properties by a high throughput process.
