Flame-Resistant Fastening Between Two Fabrics

A flame-resistant fastening between two fabrics is sought, and must be simple to operate. The connection should resist frequent flexing, and must have a breaking strength of 120 kilogram-force. If folded cross-wise, it must withstand 40 kilogram- force, and may need to stand up to direct flame for 50 seconds or more. The resulting connection between the fabrics must be aesthetically pleasing. When subjected to flame, the connection cannot emit any toxic fumes.

Eliminate Color Fading in Washable Cotton Garments

Cotton garments, especially dark-colored garments, lose their initial color through repeated washings and exposure to sunlight. Needed is a new technology or technology system that will give cotton garments improved color fastness, but which does not depend just on using a more expensive dye with higher fastness. Such a treatment could take place during one of the several stages in the manufacture of cotton garments.

Frizzy Hair Control

Materials and compounded products are sought that, when deposited on hair from a leave-on or rinse-off conditioner, will control frizzy hair and leave a positive feel to the hair. Any solution must be non-toxic and safe for use by children. It should neither produce environmental difficulties in its use or manufacture, nor affect the stability of the formulated product to which it is added. Additionally, it should not interfere with other benefits delivered. Possible materials include associative or cross-linked polymers, silicones, and non-polar oils.
