Abstract
A multifunctional nonionic or partially nonionic siloxane copolymer for modification of synthetic materials and methods for modifying synthetic materials with the siloxane copolymer are provided. Synthetic materials modified with the siloxane copolymer, and fabrics made from the modified synthetic materials, have improved hydrophilicity, thermal regulative properties, and simultaneously improved softening effects and hand.

A multifunctional siloxane copolymer for modifying synthetic materials comprised of polyamide, polyester, a combination thereof, or other materials containing carbonyl groups or amide groups, wherein the multifunctional siloxane copolymer is represented by the following compositional formula:
- wherein R1 comprises an anionic functional group,
- wherein R2 comprises a nonionic functional group,
- wherein R3 comprises at least one member selected from the group consisting of alkyl groups, phenyl groups and alkoxyl groups,
- wherein each R4 independently comprises at least one member selected from the group consisting of alkyl groups, phenyl groups, alkoxyl groups, R1 and R2,
- wherein x, y and z are each a positive integer and represent the molar numbers of the siloxane units containing R1, R2, and R3, respectively, in the siloxane copolymer, wherein the molar ratio x+y:z is about 1:1,
- wherein R1, R2, R3 and R4 can be the same or different independently, and
- wherein R1 and R2 are independently selected to provide binding ability of said siloxane copolymer to reactive functional groups in one or both of polyamide materials and polyester materials, and to provide a predetermined level of hydrophilicity, binding ability between said siloxane copolymer and the synthetic materials, and softening effect to synthetic materials subsequently treated with said multifunctional siloxane copolymer.
A multifunctional siloxane copolymer for modifying synthetic materials comprised of polyamide, polyester, a combination thereof, or other materials containing carbonyl groups or amide groups, wherein the multifunctional siloxane copolymer is represented by the following compositional formula:
- wherein R1 comprises at least one member selected from the group consisting of —CH2CH2CH2-linked nonionic carbohydrates, glucose-containing secondary amines, and alkylurea,
- wherein R2 comprises at least one member selected from the group consisting of alcohols, epoxyalkyl groups, polyalkeneoxide carbinols, anionic carbinols, nonionic carbohydrates, and anionic carbohydrates,
- wherein R3 comprises at least one member selected from the group consisting of alkyl groups, phenyl groups and alkoxyl groups,
- wherein each R4 independently comprises at least one member selected from the group consisting of alkyl groups, phenyl groups, alkoxyl groups, R1 and R2,
- wherein x, y and z are each a positive integer and represent the molar numbers of the siloxane units containing R1, R2, and R3, respectively, in the siloxane copolymer, wherein the molar ratio x+y:z is about 1:1, and
- wherein R1 and R2are independently selected to provide binding ability of said siloxane copolymer to reactive functional groups in one or both of polyamide materials and polyester materials, and to provide a predetermined level of hydrophilicity, binding ability between said siloxane copolymer and the synthetic materials, and softening effect to synthetic materials subsequently treated with said multifunctional siloxane copolymer.
