Abstract: The present invention relates to a nonwoven fabric having a relatively low level of ionic contaminates which is achieved by exposing the fabric to a deionized water wash, preferably, in-line with the nonwoven production process, thereby eliminating, or at least reducing, the need for an expensive and time consuming cleanroom laundering. The fabric is primarily comprised of continuous filament fibers and may be manufactured into such end-use products as cleaning wipes and protective clothing for cleanrooms and surface coating operations, such as automotive paintrooms. Also encompassed within this invention is a method for producing a nonwoven fabric having a relatively low level of ionic contaminates.

Abstract: Described is a process for reducing a malodour formed as a result of fatty acid derivative degradation and/or organic amine degradation taking place in a fabric care base contained in a fabric article or in a cosmetic or therapeutic base adsorbed on the human epidermis by treating the base-bearing fabric article or base-bearing human epidermis with a synergistic mixture of t-butyl phenolic compounds which may also include at least one malodour-reducing fragrance component compatible with each of the phenolic composition components. Also described are novel compositions useful in carrying out the aforementioned process.

Abstract: The present invention relates to a process for lime- and sulfide-free unhairing of skins/hides using animal and/or herbal (plant) enzymes. The process comprises presoaking the skins or hides in water for 2–6 hours, pasting an enzyme solution of animal or plant origin on the flesh or grain side of the skins/hides and leaving the solution on the skins/hides for 10–24 h at a temperature ranging from 10° C. to 60° C. The soaking liquor is removed and the hides/skins to a bath of water containing 1 to 15% of enzyme for unhairing, with or without intermittent shaking, while maintaining the pH of the bath liquor at 4.5–10.0 for 12–24 h at ambient temperature. The skins/hides are then unhaired for further processing. The total elimination of lime and sulfide in the unhairing process leads to reduced TDS (total dissolved solids), BOD (biological oxygen demand) and COD (chemical oxygen demand) in the effluent without affecting the collagen of the skin/hide or the grain pattern.

Abstract: A novel synthetic aluminium tanning agent as an alternative for chromium based tanning salts without using formaldehyde was prepared by using aromatic polymeric matrix and aluminium (III) salts as raw materials with suitable masking agents. The preparation of the syntan consists of sulphonation of aromatic molecule, which is incorporated with a polymeric network along with ligands specially designed for the complexation of aluminium (III) salts. The complex can be used as a self-tanning agent in leather industry with fairly good filling behavior. The tanned leathers exhibit shrinkage temperature about 85° C. Due to the higher precipitation point of the product, it can be used for tanning directly after deliming thus eliminating the pickling process. This product, unlike the conventional phenol based products, does not undergo photo-oxidation thereby preventing the discoloration of the tanned leathers.

Abstract: Adapting crosslinking with triglycidyl amine (TGA) to incorporate the use of a particular type of anti-calcification agent provides a broad-reaching solution to the problem in vivo bioprosthesis calcification. The anti-calcification agent in question includes a polyphosphonate compound that contains a functional group, which serves as a reaction site between the polyphosphonate and a polyepoxide. The functional group is reactive enough to dominate the reaction between the polyphosphonate and the polyepoxide, thereby excluding the chelating oxygen atoms of polyphosphonate from the reaction, protecting their anti-calcification ability. Furthermore, the high reactivity of the functional group allows the polyphosphonate to attach to the polyepoxide more completely, which improves the calcification resistance of bioprosthetic material with which the polyepoxide is crosslinked.
