Described herein are component compositions comprising a blend of a polymer resin together with silica glass beads. In certain embodiments, the components demonstrate improved abrasion resistance as do the industrial fabrics produced that comprise at least one component of the instant disclosure.

A present invention is directed to a laminated filtration media comprising a nanofiber coating applied onto a synthetic substrate. Generally, the laminated filtration media can be produced by applying the nanofiber layer onto the synthetic substrate via an electrospinning process and then thermo-mechanically bonding the nanofiber layer onto the synthetic substrate via a thermal bonding process. The laminated filtration media exhibits superior durability and can be used in a wide array of air filtration applications.

A method for preparing an anti-bacterial and anti-ultraviolet multifunctional chemical fiber includes: dissolving several soluble metal salts and a polymer complexing dispersant into water to prepare an aqueous solution; adding into a polymer monomer; reacting under microwave or hydrothermal action to obtain a polymer monomer containing multifunctional nano oxides; adding the polymer monomer with other monomer, catalyst, initiator, stabilizer, and the like into a polymerization reactor; and carrying out esterification, polycondensation or copolymerization to obtain a polymer melt, and carrying out spinning or ribbon casting and granule cutting to obtain an anti-bacterial and anti-ultraviolet multifunctional chemical fiber or masterbatch chips. By generating nano metal oxides in the monomer in situ before the polymerization reaction, small particle sizes and dispersibility of the nano metal oxide are ensured; the chemical fiber has efficient, durable antibacterial and anti-ultraviolet functions and is free of metal ion precipitation.

The method for producing a polyimide fiber includes a coagulation step of forming a polyimide precursor fiber by extruding a polyimide precursor solution containing a polyimide precursor and a compound having an acid dissociation constant (pKa) of a conjugate acid in water at 25 C. of 6.0 to 10 inclusive and an octanol-water partition coefficient (Log P) at 25 C. of 0.75 to 0.75 inclusive into a poor solvent or nonsolvent for the polyimide precursor; and a heat drawing step of forming the polyimide fiber by drawing the polyimide precursor fiber while heating same. The polyimide fiber of the present disclosure has a physical property such that the coefficient of thermal expansion thereof is in the range of 15 ppm/K to 0 ppm/K inclusive.

Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away front the printed part, resulting in a part having surface cavities.

The present invention relates to electrospun fibers comprising i) a hydrophilic polymer that is soluble in a first solvent, ii) a bioadhesive substance that is slightly soluble in said first solvent, iii) optionally, a drug substance.
