Lithium-containing nanofibers, as well as processes for making the same, are disclosed herein. In some embodiments described herein, using high throughput (e.g., gas assisted and/or water based) electrospinning processes produce nanofibers of high energy capacity materials with continuous lithium-containing matrices or discrete crystal domains.

Disclosed is a method for manufacturing a shock-absorbing lanyard for easy length adjustment of partially oriented yarn (POY). The method for manufacturing a shock-absorbing lanyard for easy length adjustment of POY according to the present disclosure includes (a) weaving a safety tube band which is a tube fabric woven using fiber yarn and rubber yarn, and placing a core material in the safety tube band at the same time, wherein the core material is made of a plurality of POY and stretches in a longitudinal direction to absorb shock; (b) adjusting a length of the core material after weaving the safety tube band; and (c) combining the safety tube band with the core material to form a combination.

Disclosed are methods that utilize the differences in physical properties between two coating fluids to form core-shell particles or core-shell fibers by coaxial free-surface electrospinning. The methods are able to achieve higher productivity than known methods, and are tunable. Nonwoven fiber mats of electrospun fibers have garnered much scientific and commercial interest in recent years due to their unique properties, such as their high porosity, high surface area and small diameter fibers.

An antimicrobial photoactive nanofibrous polymer material with polymer nanofibers has hydrophobic domains and hydrophilic domains. At least one photoactive molecule encapsulated in the hydrophobic domains of the polymer nanofibers is a photoactive molecule being capable of releasing or generating an antimicrobially active substance after irradiation by visible light. The antimicrobial photoactive nanofibrous polymer material may be used for antimicrobial wound dressings, antimicrobial cosmetic facial masks, self-disinfecting face masks or respirators, self-disinfecting filters for filtration of gases or liquids, self-disinfecting textile and products made thereof, self-disinfecting packaging material or protective agriculture foils.

The present invention relates to an electroconductive polymer fiber having an integrated electroconductive layer on at least a part of its surface. Since the electroconductive layer of the present invention is integrally formed on the core layer of the fiber, the electroconductive polymer fiber has excellent bending resistance. The fabric comprising the electroconductive polymer fiber of the present invention retains the electrical conductivity even after repeated washing and bending. The electroconductive polymer fiber of the present invention can be used for antistatic products, electromagnetic shielding materials or stealth materials.

A method of electrospinning a plurality of fibers (150) is provided. The method includes providing at least one collector (120) and a single extruder (110). The extruder (110) includes a channel (112) housing a precursor liquid (190). The method includes dispensing the precursor liquid (190) from the extruder (110), and in response to an electric field, collecting fibers (150) formed from the precursor liquid (190) by a collector (120) to form a hollow casing (210) of fibers (150).

A mat structure includes a main body. The main body has a property of toughness. The main body includes a first face and a second face. The main body is formed with a cut line in a middle. The cut line is formed through cutting from the second face of the main body. The cut line has a depth that is smaller than a thickness of the main body. The main body is further provided with at least one surface layer. With the depth of the cut line being smaller than the thickness of the main body and the main body having a property of toughness, the main body can be folded without causing damage. Further, when a die cutter is applied to cut and make the cut line, an allowable tolerance range for the die cutter is enlarged.
