20220356619 · 2022-11-10 ·

A moisture-retentive fabric medium includes a hydrophilic, thermoplastic polyester fiber as a blend of from 10-905% or 20-80% by total weight of textile fibers and 90-10% or 80-20% by total weight of hydrophilic textile fibers and less than 0.5% by weight of total fabric medium as microfibrillated cellulose fiber and less than 0.05% by weight superabsorbent polymers, the polyester having a melting point between 190-500 F when measured in accordance with ASTM D-3418.

WATER-DISPERSIBLE ARTICLE INCLUDING WATER-DISPERSIBLE CORE CONSTRUCTION

An article for cleaning or hand-washing an object includes a core substrate comprising a plurality of fibers including a resin. The core substrate has one or more abrasive surfaces and contains an active cleaning formulation. The resin and the core substrate are water-dispersible upon contact with water at a low temperature, such as 40° C. or below, and water-soluble upon contact with water at a higher temperature. Also disclosed are methods for making the article.

SUBSTITUTED THIOLATE SALT MELT ADDITIVES

Charged polymeric webs, such as electret webs, include a thermoplastic resin and a charge-enhancing additive. The additives are substituted heterocyclic thiolate salts. The heterocyclic thiolate salt has 2 nitrogen groups and a third group that may be an NH, N—NH.sub.2, O, or S group. The substituent group is an aromatic or heterocyclic aromatic group. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.

A gas filtering medium is composed of hydrophobic polyester fiber as from 20-80% by total weight of textile fibers and 80-20% by total weight of hydrophilic textile fibers and a microfibrillated cellulose fiber in a weight/weight ratio of 1.5-8.5/100 parts by weight of total textile fiber.

Thermally and dimensionally stabilized compositions and methods of making same

Thermally stable absorbable fiber populations, i.e. fiber populations that do not undergo thermally induced crystallization, can be intermixed with thermally unstable fibers to yield a stabilizing effect without altering morphological properties of a fiber system. Via this, one may minimize thermally induced shrinkage and maintain physical properties of electrospun materials in the as-formed state.
