Abstract
Functionalized particles comprising a shell and a core and a payload that is embedded or entrapped, wherein the shell matrix is obtained by interfacial polymerisation of vinyltriethoxy silane and at least one other ethylenically unsaturated monomer copolymerizable with vinyltriethoxy silane, the functionalized particles being capable to chemically bind to a substrate, are suitable as controlled release systems for textile applications to impart durable softness and excellent water retention even after multiple laundries.
Claims20
Functionalized particles comprising a shell and a core and a payload that is embedded or entrapped, wherein the shell comprises a matrix obtained by interfacial polymerisation of ethylenically unsaturated monomers comprising vinyltriethoxy silane and styrene, wherein a majority of the ethylenically unsaturated monomers by weight comprises styrene, said functionalized particles being capable to chemically bind to a substrate, wherein the payload is a particle or water insoluble droplet.
Functionalized particles comprising a polymeric shell and a polysiloxane that is embedded or entrapped, wherein the polymeric shell is obtained by polymerization of ethylenically unsaturated monomers comprising vinyltriethoxy silane, styrene and glycidyl methacrylate, wherein a majority of the ethylenically unsaturated monomers comprises styrene, and wherein the polymeric shell is capable of being covalently bound to a substrate comprising —OH, —NH or —SH groups.
A modified textile comprising functionalized particles and a textile, the functionalized particles comprising a polymeric shell and a silicone softener that is embedded or entrapped, wherein the shell is obtained by polymerization of ethylenically unsaturated monomers comprising vinyltriethoxy silane, styrene and glycidyl methacrylate, wherein a majority of the ethylenically unsaturated monomers comprises styrene, and wherein the polymeric shell is covalently bonded to the textile.
