Compositions and methods are described that provide cellulosic and non-cellulosic fabrics with durable antimicrobial properties. Application of a coating that includes polyhexamethylene biguanide, polyethylene glycol, and a binder to a fabric followed by drying and curing was found to provide antimicrobial properties that are retained through over 100 washings under aggressive hospital washing conditions. In addition, tactile properties and tear resistance of the treated fabrics are maintained or improved.

Aminocarboxylate chelating agents are described having generic formulas selected from the group consisting of (A) and (B) wherein R.sub.1 through R.sub.5 are as further defined herein. Compositions containing at least one of these aminocarboxylate chelating agents are also described. The compositions are useful for example as detergent compositions for laundering clothing and compositions for cleaning dishes, in particular cleaning dishes using automatic dish washing devices.

A method of preparing a fabric for perspiration exhaust pajamas and underclothing includes the following steps: (1) grey cloth weaving: weaving a perspiration exhaust fiber, a regenerated cellulose fiber, and spandex into a grey cloth; (2) singeing: singeing the grey cloth to obtain a singed grey cloth through a two-face-two-back singeing; and (3) moisture adsorption and perspiration exhaust finishing: immersing the singed grey cloth in a finishing liquid, taking out the singed grey cloth for drying, baking, washing, and then drying to a constant weight to obtain the fabric for perspiration exhaust pajamas and underclothing.

Polyester-free cotton is obtained from a fabric and/or fibers containing polyester and cotton by reacting the fabric and/or fibers with an amine organocatalyst and/or carboxylic acid salt of same and an alcohol solvent. The reaction, which may be run in batches or as a continuous flow process, recovers (i) polyester-free cotton as a solid inert by-product of the reaction, (ii) the amine organocatalyst and/or carboxylic acid salt of same for reuse, (iii) a polyester monomer product, and (iv) unreacted alcohol. The reaction works on any polyester-cotton fabric and/or fibers, including those that have at least one additional material, such as polyethers polyolefins, polyurethanes, nylon, rayon, acetate, viscose, modal, acrylic, wool, and combinations thereof.

A dustproof fabric which includes an antistatic dustproof fabric having excellent antistatic properties, a high air permeability and high-level dustproof properties is provided. The antistatic dustproof fabric includes two or more fiber layers. At least one of the two or more fiber layers is a fiber layer 1 containing an antistatic agent. The polarity of the antistatic agent is opposite to the polarity of the zeta potential of the fiber layer 1. At least one of the two or more fiber layers is a fiber layer 2 which is electrically charged.

An article may include a material having a surface containing at least one zinc oxide and/or salt, and at least one antioxidant. A method of using a mixture including at least one zinc oxide and/or salt, and at least one antioxidant, as bacteriostatic agent may include: applying the mixture to a surface of an article.
