Fabrication of meta-aramid fibrid by precipitation

Fibers and Polymers, 2012
“Fibrid”, a type of fibrous particle used for binding, and the meta-aramid fibrids were successfully prepared by injecting the meta-aramid solution into the high shearing coagulation bath in this paper. The meta-aramid solution was prepared by dissolving the meta-aramid fibers in LiCl/DMAc solving system, and the mixture of water and DMAc was used as ...

Structurally colored aramid fabric construction and its application as a recyclable photonic catalyst.

Soft Matter, 2023
Structural colors can be used in fabric coloring due to their bright color and non-fading properties. However, it is still a challenge to construct structural color on high crystallinity, smooth surfaced and yellow colored aramid fabrics. Herein, for the

Polymeric composite materials reinforced with aramide fabrics

Fibre Chemistry, 1990
-- Hot-pressed incombustible polymeric materials have been developed which have a low density; these are based on an epoxy or polyimide binder, reinforced with aramide fabrics; these can be used at temperatures up to 473 K. Production of these has been organized in the experimental works of the LenNII “Khimvolokno.”

A study of yarn friction in aramid fabrics

Polymer Science Series A, 2012
Energy dissipation by the friction forces of yarns in aramid fabrics with different weave patterns is studied. The upper theoretical limit of the ability of fibers to absorb the energy of transverse impact is determined. The maximum pull-out force for yarns of a plain-weave fabric nonlinearly depends on the number of pulled-out yarns.
