TL;DR: In this paper, isocyanate-terminated polyurethane pre-polymers are usually cured by exposure to the atmosphere for 4-8 days, and the suggested industrial procedures are to tumble in a dryer that has provision for open steam injection or to hang in a steambox.
Abstract: After application to woo) from organic solvent, isocyanate-terminated polyurethane pre-polymers are usually cured by exposure to the atmosphere for 4–8 days. The activity of the resin and the humidity of the atmosphere have an important effect on the rate of curing. Complete development of the shrink-resisting effect can be achieved in 15 min or less by steam-pressing or by exposure to saturated steam at 100dC. The suggested industrial procedures are to tumble in a dryer that has provision for open steam injection or to hang in a steam-box. Reduction of the curing time by application of an organometallic catalyst with the resin tends to cause difficulties in maintenance of the solvent machine and in garment pressing.

TL;DR: In this article, various polyfunctional compounds were applied to wool in attempts to stabilize the temporary improvements in wrinkle-recovery brought about byannealing, and several reactive systems involving formaldehyde were found to produce the desired permanently improved wrinkle recovery.
Abstract: An investigation is described in which various polyfunctional compounds were applied to wool in attempts to stabilize the temporary improvements in wrinkle-recovery brought about by ‘annealing’. Several reactive systems involving formaldehyde were found to produce the desired permanently improved wrinkle-recovery.

TL;DR: Prolonged steaming of wool in the presence of reducing agents, alkalies, or water alone produces set that is stable to machine-washing by lowering the thiol content of the wool and thus inhibiting thiol-disulphide interchange rather than by secondary effects, such as cross-linking or denaturation as discussed by the authors.

TL;DR: In this article, the crimp in wool yarn produced by the knit-deknit method can be made stable to release in hot water while in the extended configuration by setting the knitted fabric with bisulphite and then applying stabilising techniques previously found effective on pleated fabric.
Abstract: The crimp in wool yarn produced by the knit-deknit method can be made stable to release in hot water while in the extended configuration by setting the knitted fabric with bisulphite and then applying stabilising techniques previously found effective on pleated fabric. These include oxidation, crosslinking and application of reactive polymers.
