In one aspect of the present disclosure, a streamlined body for passing through a fluid is provided. The streamlined body includes an outer surface defining a leading edge and a trailing edge. The leading edge is oriented to pass through the fluid before the trailing edge during movement of the body through the fluid. The streamlined body further includes a plurality of fibers coupled to the outer surface. Each fiber of the plurality of fibers projects away from the outer surface.

Articles of wear having one or more textiles that include a low processing temperature polymeric composition and a high processing temperature polymeric composition, and methods of manufacturing the same are disclosed. The low processing temperature polymeric composition and the high processing temperature polymeric composition can be selectively incorporated into a textile to provide one or more structural properties and/or other advantageous properties to the article. The textile can be thermoformed to impart such structural and/or other advantageous properties to the article of wear. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

The present disclosure relates to an antibacterial composition, a filter using the same, and a home appliance such as an air conditioner comprising the filter. More specifically, the antibacterial composition according to the present disclosure comprises a polymer resin, and an antibacterial additive composed of an antibacterial metal and an antibacterial metal oxide, and thus a filter manufactured therefrom has excellent antibacterial activity and also maintains antibacterial performance even if washed.

A degradable polyester fiber and its preparation method are disclosed. The preparation method is to cool a PET melt dispersing with doped ZrO.sub.2 powder by ring-blowing after extruded from a trilobal spinneret hole on a spinneret, and manufacture a fully drawn yarn (FDY) according to an FDY process with the PET melt, then the degradable polyester fiber is prepared after a relaxation heat treatment. The trilobal spinneret hole on the spinneret has three leaves with unequal lengths and angles, and all the trilobal spinneret holes are distributed in concentric circles, with a center line of the leaf opposite to the smallest angle in each trilobal spinneret hole passing through the center of the circle, and pointing away from the center of the circle. The process is simple, and the obtain fiber has good performances in degradation and elasticity.

Thermally stable absorbable fiber populations, i.e. fiber populations that do not undergo thermally induced crystallization, can be intermixed with thermally unstable fibers to yield a stabilizing effect without altering morphological properties of a fiber system. Via this, one may minimize thermally induced shrinkage and maintain physical properties of electrospun materials in the as-formed state.

A polyester resin comprises a dicarboxylic acid component and a glycol component, wherein the glycol component contains ethylene glycol together with diethylene glycol and triethylene glycol, and a content of triethylene glycol in the glycol component is more than 0.1 mol % and 5.5 mol % or less.

A liquid color masterbatch composition for fabricating a colored fiber includes 30.0 to 44.4 parts by weight of a colorant, 14.0 to 44.4 parts by weight of a lubricant, and 11.2 to 56.0 parts by weight of a carrier, in which a viscosity of the liquid color masterbatch composition between 13000 cP and 18000 cP.
