摘要:
The present invention pertains to a process for manufacturing one or more fluoropolymer fibres, said process comprising the following steps: (i) providing a liquid composition [composition (C1)] comprising: —at least one fluoropolymer comprising at least one hydroxyl end group [polymer (FOH)L and—a liquid medium comprising at least one organic solvent [solvent (S)]; (ii) contacting the composition (C1) provided in step (i) with at least one metal compound [compound (M)] of formula (I) here below: X4-mAYm (I) wherein X is a hydrocarbon group, optionally comprising one or more functional groups, m is an integer from 1 to 4, A is a metal selected from the group consisting of Si, Ti and Zr, and Y is a hydrolysable group selected from the group consisting of an alkoxy group, an acyloxy group and a hydroxyl group, thereby providing a liquid composition [composition (C2)]; (iii) submitting to at least partial hydrolysis and/or polycondensation the composition (C2) provided in step (ii) thereby providing a liquid composition [composition (C3)] comprising at least one fluoropolymer hybrid organic/inorganic composite; (iv) processing the composition (C3) provided in step (iii) by electrospinning thereby providing one or more fluoropolymer fibres; (v) drying the fluoropolymer fibre(s) provided in step (iv); and (vi) optionally, submitting to compression the fluoropolymer fibre(s) provided in step (v) at a temperature comprised between 50° C. and 300° C. The invention also pertains to a process for the manufacture of said fluoropolymer fibre(s) and to uses of said fluoropolymer fibre(s) in various applications.
摘要:
A non−woven fabric which comprises fluororesin fibers as a primary component, wherein the fibers are intermingled with one another; the non−woven fabric which is further subjected to a pressurizing and heating treatment or to a stretching treatment. The non−woven fabric has excellent mechanical characteristics.
摘要:
A fiber, comprising one or more fluoropolymers, wherein the fiber is formed by a rotational spinning process. A fabric made using a collection of a plurality of the fibers, and a yard comprising the fibers, wherein the yarn comprises a continuous plurality of fibers that are pulled and twisted to form the yarn.
摘要:
A method of producing fibers, includes placing a composition that includes one or more fluoropolymers in the body of a fiber producing device and rotating the device at a speed sufficient to eject material from the fiber producing device to form fluoropolymer microfibers and/or nanofibers.
