A human hair fiber treatment agent for treating human hair fibers having free ends at both ends, comprising the following components (A) to (C) in the formulation thereof: (A): formaldehyde or hydrate thereof; (B): melamine derivative represented by the formula (1):

##STR00001##

wherein R.sup.1 to R.sup.3 are the same or different and each represent a hydrogen atom, a hydroxymethylamino group, a hydroxy group, a halogen atom, a phenyl group, a linear or branched alkyl group or alkenyl group having 1 or more and 6 or less carbon atoms, or a linear or branched alkoxy group or alkenyloxy group having 1 or more and 6 or less carbon atoms; and (C): water.

An antibacterial antifungal fiber structure is provided, which comprises a polyester mixed fiber structure, and an antibacterial antifungal agent (A) and an antibacterial antifungal agent fixation aid (B) contained in the polyester mixed fiber structure, wherein the antibacterial antifungal agent (A) comprises a pyridine antibacterial antifungal agent, wherein the antibacterial antifungal agent fixation aid (B) comprises at least one compound selected from a first group (b1) comprising a surfactant, a second group (b2) comprising an organic solvent, and a third group (b3) comprising an aromatic compound and a urea compound. The antibacterial antifungal fiber structure is excellent in antibacterial and antifungal properties because the antibacterial antifungal agent (A) is fixed together with the antibacterial antifungal agent fixation aid (B) in fibers of the polyester mixed fiber structure.

Provided is an adhesive composition capable of achieving excellent adhesion and mechanical stability even when it contains no formalin or resorcin. The adhesive composition contains (A) rubber latex, and (B) a compound having an acrylamide structure.

A human hair fiber treatment agent comprised of one or more compositions for treating human hair fibers having free ends at both ends, wherein the human hair fiber treatment agent comprises the following components (A) to (C) in the formulation thereof: (A): at least one formaldehyde derivative selected from the group consisting of formaldehyde, and the like; (B): phenol compound(s) having electron-donating group(s) on at least one of the meta positions and having hydrogen atom(s) on at least one of the ortho positions and the para position, with the proviso that the electron-donating group at the meta position optionally forms, together with a carbon atom attached thereto, a benzene ring optionally substituted with hydroxy group(s); and (C): water.

Processes for making weather resistant, slow-decaying, durable natural fiber/coir geotextiles produce geotextiles having flexibility, permeability, light weight and cost-effective characteristics. In this process an in situ chemical grafting using a mixture of Cashew Nut Shell Liquid and aminoalkyl trialkoxysilanes with cellulose was done followed by curing in presence of sunlight, UV light or heat. The developed product showed durability and strength more than that of natural fiber/fabric and retaining natural fiber/fabric/geotextiles characteristics. The geotextiles have delayed bio-deterioration having wider long-term end use/applications. This process of making durable geotextiles is eco-friendly and retains the desired characteristic.
