Abstract
Abstract A method of treating fibrous materials comprises applying a composition comprising as sole amine containing organosilicon compound the reaction product of an organopolysiloxane having groups with one or more monoepoxides. X denotes a monovalent C, - 8 hydrocarbon group, R is an alkylene group, R' is H or a group of the formula RZ, Z being NHX, NH 2 , NHRNH 2 or NHRNHX. No more than 10% of all amine groups may be primary amine groups. The composition is preferably applied as an emulsion. Fibres thus treated are soft and show less yellowing than the prior art.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A method of treating fibrous materials which comprises the application to the fibrous materials of a composition comprising an amine containing organosilicon compound, characterised in that the sole amine containing organosilicon compound in the composition is the reaction product of an organopolysiloxane having at least one unit of the general formula and at least one unit of the general formula with one or more monoepoxides wherein X denotes a monovalent hydrocarbon group having up to 8 carbon atoms, R denotes a divalent alkylene group, R denotes a hydrogen atom or a group of the formula RZ wherein Z is NHX, NH 2 , NHRNH 2 or NHRNHX, a has a value of 1 or 2 and b has a value of 2 or 3.
Claim 2
Independent Claim
124 words
A method of treating fibrous materials which comprises the application to the fibrous materials of a composition comprising an amine containing organosilicon compound, characterised in that the sole amine containing organosilicon compound in the composition is the reaction product of an organopolysiloxane having at least one unit of the general formula and at least one unit of the general formula with one or more monoepoxides wherein X denotes a monovalent hydrocarbon group having up to 8 carbon atoms, R denotes a divalent alkylene group, R denotes a hydrogen atom or a group of the formula RZ wherein Z is NHX, NH 2 , NHRNH 2 or NHRNHX, a has a value of 1 or 2 and b has a value of 2 or 3.
Claim 3
Dependent Claim
27 words
A method according to Claim 1 characterised in that the organopolysiloxane is a substantially linear polydiorganosiloxane wherein at least 80% of all X groups are methyl groups.
Claim 4
Dependent Claim
22 words
A method according to either Claim 1 or Claim 2 characterised in that the organopolysiloxane comprises from 100 to 500 siloxane units.
Claim 5
Independent Claim
30 words
A method according to any one of the preceding claims characterised in that from 1 to 10 mole% of all siloxane units of the organopolysiloxane are units of the formula
Claim 6
Independent Claim
29 words
A method according to any one of the preceding claims characterised in that the monoepoxide has the general formula wherein n has a value of from 0 to 8.
Claim 7
Independent Claim
40 words
A method according to any one of the preceding claims characterised in that the majority of amine groups in the reaction product are tertiary amine groups, there being no more than 10% primary amine groups present in said reaction product.
Claim 8
Independent Claim
25 words
A method according to any one of the preceding claims characterised in that the reaction product does not contain any primary or secondary amine groups.
Claim 9
Independent Claim
22 words
A method according to any one of the preceding claims characterised in that the composition is in the form of an emulsion.
Claim 10
Independent Claim
25 words
A method according to any one of the preceding claims characterised in that the composition comprises no other amine containing compounds than the reaction product.
