International Classification:

B32B 27/04

US Classification:

442123, 811559

Abstract:

Provided herein are processes for topically applying an antimicrobial finish to a textile substrate, such as a yarn, a fabric, a composite, or an assembled article (for example, a garment). Specifically, the antimicrobial finish is based on hindered amine compounds that are applied in an aqueous bath (such as a commercial or home laundry setting), using the factors of pH and compound solubility to promote the formation of a durable antimicrobial halamine finish. Advantageously, the antimicrobial finish, which may be applied to fabrics made of any of a variety of fiber types and combinations of fiber types, has been found to be durable to repeated launderings.

International Classification:

C08L 53/00
C08G 18/42

US Classification:

524505, 524500

Abstract:

A polymer composition with blocks of hydrophobes attached to or within the backbone of an associative thickener. The blocks are composed of two or more units of the same or different hydrophobes whereby the hydrophobe is reversibly switched between being hydrophilic and hydrophobic in nature. When the hydrophobe is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this hydrophobe is rendered hydrophobic, the thickener performs its thickening function efficiently, especially in tinted systems. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened.

International Classification:

C08L 5/16
C08L 79/02
C08L 85/02

US Classification:

524 48, 524612, 524610, 524501

Abstract:

A composition and method whereby the same group that is attached to or within the backbone of an associative thickener is reversibly switched between being hydrophilic and hydrophobic in nature. The group comprises a tertiary amine, or tertiary phosphine and has a hydrocarbon radical bonded to the amine nitrogen atom or phosphine phosphorus atom, which hydrocarbon radical is pendant to the backbone and contains fewer than 10 carbon atoms. When the group that is attached to or within the backbone is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this group is rendered hydrophobic, the thickener performs its thickening function efficiently. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened.

US Classification:

524500, 525460

Abstract:

The present invention relates to a hydrophobically modified alkylene oxide urethane polymer comprising structural units of a polyalkylene glycol, an alkoxylated polyol having 50 to 250 repeating alkylene oxide units, an aliphatic diisocyanate, and a capping agent, and a process for preparing the polymer. The composition of the present invention is useful as a rheology modifier for coating compositions.
