Use of poly(alkylamine)-derived (PAD) self-supported cross-linked polymeric ammonium salts and ionomer hydrogels for adsorbing and desorbing organic contaminants, specifically per and polyfluoro alkyl substances (PFAS) from water.

Cross-linked polymeric ammonium salts and their use in absorbing organic contaminants

The present invention is directed toward a process for making poly alpha-1,3-glucan formate films. These films are translucent or transparent and can be used in packaging applications.

Production of poly alpha-1,3-glucan formate films

A method for subsurface irrigation having the steps of; providing one or more hydrophobic porous uncoated tubes having a hydro head (HH), locating the tubes with at least a portion of their length within the rhizosphere of plants to be irrigated, and passing an aqueous irrigation liquid into the tubes during the growth phase of the plants to be irrigated at an applied pressure at or below HH. The tubes may be located in the proximity of seeds which become the plants to be irrigated following their germination. In this embodiment, aqueous irrigation fluid is passed into the tubes during a germination phase of the seeds at an applied pressure that is at least 10% higher than the applied pressure during the growth phase of the plants.

A solid article formed from poly alpha-1,3-glucan and wood pulp is disclosed as are methods for making the solid article. The articles are not water sensitive and are useful for producing strong molded articles from wood pulp.

Solid articles from poly alpha-1,3-glucan and wood pulp

A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

Stretchable multiple component nonwoven fabrics and methods for preparing

The invention relates to nonwoven fabrics containing polymeric multiple component fibers which include a core component and a plurality of wing components attached to the core. The polymeric core component has an elasticity that is greater than the elasticity of at least one of the wing polymeric components. The fibers assume a spiral twist configuration in which the plurality of wings substantially spiral about the core. In a preferred embodiment, the nonwoven fabrics have elastic stretch and recovery properties with a textile-like hand.

Stretchable multiple-component nonwoven fabrics and methods for preparing

This invention relates to an improved method for preparing stretchable multiple-component bonded composite sheets which involves bonding a fibrous layer of spirally-crimpable multiple-component continuous filaments or staple fibers to one or more non-spirally-crimpable layers using an array of intermittent mechanical, chemical, or thermal bonds, and heating the bonded composite to activate the spiral crimp of the fibers in the spirally-crimpable layer. Multi-layer nonwoven fabrics prepared according to the method of the current invention have an improved combination of strength, aesthetics, stretch-recovery properties, and textile hand and drape compared to multiple-component nonwoven fabrics known in the art.
