摘要： Provided is a method of manufacturing a dental cord. The method including: producing a spinning solution by dissolving a fiber-moldable hydrophobic polymer material in a solvent; spinning the spinning solution to obtain a polymer nanofiber web composed of nanofibers and including three-dimensional micropores; laminating the polymer nanofiber web to obtain a polymer membrane; slitting the polymer membrane to obtain a nanofiber tape yarn; hydrophilic-treating the nanofiber tape yarn to obtain a hydrophilic-treated nanofiber tape yarn; plying and twisting the hydrophilic-treated nanofiber tape yarn with a covered yarn to obtain a nanofiber multiple yarn; and impregnating the nanofiber multiple yarn with a hemostatic agent.

摘要： IR-emitting or reflecting polymer fibers are formed by blending a high concentration of IR-emitting or reflecting particles with a thermoplastic polymer and meltblowing fibers which have an average diameter of 20 μ or less. The meltblowing process allows for inclusion of a high concentration of the IR-emitting or reflecting particles, yet allows fibers to be formed. These can be formed into a soft, air-permeable, nonwoven web. The fibers can be monocomponent or bicomponent or multicomponent and can be textured or shaped.

The neutralized sulfonated thermoplastic polymer has about 10 to about 100 meq. SO.sub.3 H per 100 grams of sulfonated thermoplastic polymer, of which at least 95% is neutralized with a cation being selected from the group consisting essentially of antimony, iron, lead, aluminum, or Groups I-A, II-A, I-B or II-B of the Periodic Table of Elements and mixture thereof. The solution of the neutralized sulfonated thermoplastic polymer having a Brookfield viscosity at room temperature at about 6 rpm of about 1,000 to about 200,000 cps is fabricated into fibers by wet or dry spinning through a spinner having a plurality of orifices therein. The resultant fibers exhibit improved dimensional stability and resistance to solvents and temperature when fabricated into a fabric.
