Verfahren zum Behandeln faserfoermiger Gegenstaende mittels Mikrokapseln,die ein hydrophobes Behandlungsmittel enthalten

摘要

A fibrous article such as yarn, woven and knitted fabric and non-woven fabric is treated with hydrophobic treating agent by applying microcapsules composed of a core constitutent consisting of a non-aqueous solvent solution of the hydrophobic treating agent and a wall constituent containing the core constituent and made up of a thin synthetic resin shell and having a low tenacity at break of at most 100 g/cm2, and then by breaking the applied microcapsules at a breaking force of at least 100 g/cm2 so as to impregnate the fibrous article with the non-aqueous solvent solution which flows out from the broken microcapsules.
