Definitions
- This invention relates to a method of treating fibrous materials and more specifically to a method of treating textile materials.
- fibrous materials is meant fibres of synthetic or naturally occurring materials, for example wool, cotton, polyester, carbon and blends of these.
- the invention relates to the treatment of the fibres as such as well as to the treatment of fabrics or textiles incorporating the fibres.
- compositions comprising amine-containing silicon compounds for imparting desirable properties, e.g. softness, water repellency, lubricity and crease resistance thereto.
- the GB-A-1 491 747 for example provides a composition for treatment of synthetic fibres which comprises 1 part of certain aminosilanes and 1 to 20 parts of certain epoxysiloxanes.
- the GB-A-1 296 136 provides a process for the treatment of synthetic organic textile fibres which includes the treatment with a composition comprising either a) a mixture of an aminosiloxane and a polyepoxide, b) a mixture of a liquid epoxysiloxane and a polyamine or c) a mixture of a liquid epoxysiloxane and an aminosiloxane.
- a composition comprising either a) a mixture of an aminosiloxane and a polyepoxide, b) a mixture of a liquid epoxysiloxane and a polyamine or c) a mixture of a liquid epoxysiloxane and an aminosiloxane.
- these materials tend to give a certain amount of yellowing of the treated fibres.
- an improved treating composition can be made by restricting the amine-containing organosiloxane to those which are prereacted with a monoepoxide.
- a method of treating fibrous materials which comprises the application to fibrous materials of a composition comprising as sole amine-containing organosilicon compound the reaction product of a organopolysiloxane having at least one unit of the general formula 03-aSiX a R-NH-2 R' and at least one unit having the general formula 04-bSi-X b with one or more monoepoxides, wherein X de- notes a monovalent hydrocarbon having up to 8 carbon atoms, R denotes a divalent alkylene group, R'denotes a hydrogen atom or a group of the formula R-Z, 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.
- the organopolysiloxane used in the preparation of the reaction product may be any siloxane polymer having at least 1 unit of the general formula and at least one unit having the general formula .
- it is a substantially linear polydiorganosiloxane polymer, although small amounts of units 2 which cause branching of the siloxane are possible.
- Such units which should not be present in more than 5% of the total number of units, have the general structure O3SiX.
- the substituent X may be any hydrocarbon group having up to 8 carbon atoms, for example alkyl, aryl, alkenyl, alkylaryl and arylalkyl.
- X denotes a lower alkyl group.
- X groups are methyl groups. It is, however, possible that small amounts of other substituents are present on silicon atoms, for example hydroxyl or alkoxy groups.
- the group R is a divalent alkylene group, preferably having up to 8 carbon atoms, most preferably from 3 to 8 carbon atoms. Examples of the R group include dimethylene, propylene, isobutylene and hexylene.
- the groups R' may be hydrogen or a group of the formula RZ, wherein Z denotes a primary or secondary amine group or a diamine of the formula NHRNH 2 or NHRNHX.
- a has a value of 1 or 2, which means that the unit may be located in the siloxane chain or may be an end-unit of the siloxane chain.
- the amine-containing substituent are OSi(CH 3 )(CH 2 ) 3 NH 2 , OSi(CH 3 )CH 2 CH(CH 3 )CH 2 NH 2 , OSi(CH 3 )CH 2 CH(CH 3 )CH 2 NH(CH 2 ) 2 NH 2 , O 1 ⁇ 2 Si(CH 3 ) 2 CH 2 CH(CH 3 )CH 2 NH(CH 2 CH 3 ), O 1 ⁇ 2 Si(CH 3 ) 2 (CH 2 ) 3 NH(CH 2 ) 3 NH(CH 2 ) 3 NH 2 .
- the other units of the organopolysiloxane are units of the general formula wherein b has a value of 2 or 3 and X has the meaning as above. This means that the units may be present in the siloxane chain or as endgroups of the chain. It is preferred that polydiorganosiloxane having from to 10 to 1000 siloxane units, particularly from 100 to 500 units, most preferably about 400 units are used.
- the viscosity of the polydiorganosiloxane tends to determine the softness which is imparted to the treated materials, the higher the viscosity, the softer the finish. However, for reasons of practicality it is preferred to use those materials which are liquid at room temperature.
- Suitable organopolysiloxanes for the preparation of the reaction product for use in the method of the invention are known in the art and many are commercially available. They can be made by methods known in the art, for example by the condensation of aminofunctional silanes or hydrolysis products thereof with cyclic siloxanes in the presence of endblocking units, for example those provided by hexamethyldisiloxanes.
- Monoepoxides employed in the preparation of the reaction product are organic compounds having one epoxy group.
- epoxy is meant a group composed of oxirane oxygen attached to two vicinal carbon atoms.
- Monoepoxides which are suitable for use in the present invention are those wherein the substituent of the said vicinal carbon atoms are hydrogen, hydrocarbon groups or ether or ester containing hydrocarbon groups.
- one of the carbon atoms has only hydrogen atoms while the other carbon atom has an alkyl group attached to it, which may range from methyl to a linear C 21 alkyl group.
- Most preferred are those monoepoxides wherein the alkyl group has from 1 to 10 carbon atoms, especially from 1 to 4 carbon atoms.
- Suitable monoepoxides are ethylene oxide, propylene oxide, butadiene monoxide, 2,3-epoxy-cyclopentane, substituted olefin oxides, e.g. 2, 3-epoxy-propylbenzene, epoxy alcohols, e.g. glycidol, 2,3-epoxy- cyclopentanol, 3,4-epoxy-6-methylcyclohexylmethane, glycidyl ethers, e.g. phenyl glycidyl ether, butyl glycidyl ether or glycidyl esters, e.g.glycidyl acetate.
- Preferred are those monoepoxides of the general formula wherein n has a value of from 0 to 20, preferably 0 to 8, most preferably 0 to 3.
- the reaction product for use in the method of the invention may be prepared according to known methods.
- the two reagents may be reacted together in the presence of a low molecular weight aliphatic alcohol or in the presence of a catalytic amount of water.
- the reaction can be carried out at room temperature in the presence of such catalyst but is preferably carried out at increased temperatures, for example temperatures of 50°C or more.
- a solvent which may be the alcohol mentioned above or other suitable solvents.
- the amount of monoepoxide used in the reaction should be such that no more than 10% of all amine groups in the organopolysiloxane are retained unreacted in the reaction product.
- two monoepoxide molecules can react with the amine. It is preferred that the majority of the amino groups in the reaction product are tertiary amine groups, although the presence of secondary amine groups to the exclusion of tertiary amine groups is also acceptable.
- the amine groups in the reaction product may thus be tertiary, secondary, a mixture of these, or a mixture of either or both with up to a maximum of 10% primary amine groups.
- reaction product is used in the method of the invention, and not a mere mixture of the polydiorganosiloxane and the monoepoxide.
- Mere mixtures which contain polydiorganosiloxanes having relatively high amounts of primary amine groups are not satisfactory, since they will still display a yellowing of the treated materials. Even a mixture of the two components in the presence of water, e.g. by using an emulsion, is unsatisfactory as the yellowing upon treatment with such mixtures or emulsions is worse than treatment according to the invention.
- no primary amines are retained in the reaction product. Most preferably no secondary amines are present either in the reaction product.
- the method of the invention comprises the application to fibrous materials of a composition comprising as sole amine-containing compound the reaction product as described above.
- This application may be done in any convenient way.
- Application methods which are suitable include padding, dipping and spraying of a composition comprising the reaction product.
- the compositions used may be in any suitable form, e.g. solutions, dispersions or emulsions.
- the dispersions may be in aqueous or solvent based materials while the emulsions are preferably oil-in-water type emulsions.
- emulsions particularly microemulsions according to European patent specification 138192.
- Compositions which are useful in the method of the invention may comprise other ingredients which are useful in treatment compositions forfibrous materials, e.g. fatty acid softeners. Other ingredients e.g. surfactants in the emulsions are also useful. It is, however, preferred that the composition comprises no amine-containing compounds other than the reaction product.
- the method of the invention is suitable for the treatment of both naturally occurring and synthetic fibres, for example carbon fibres, polyester fibres, cotton fibres and blends of cotton and polyester fibres.
- the application may be done at the stage of making the fibres, at the stage of producing the fabrics or in a special treating step later, for example during laundering of a textile fabric.
- Application may be followed by drying at room temperature or at increased temperatures. After the drying stage a further heat treatment of the fibrous materials is preferred.
- the latter is particularly useful when the textile fabrics are treated at the time of their production.
- the presence of small amounts of primary amine groups on the reaction product will increase the durability of the finish on the fibrous materials, especially when they are subjected to laundering operations.
- Fibrous materials and textiles which are treated according to the method of the invention have an improved softener and lubricity, a pleasant feel and handle, without suffering from yellowing due to the treatment.
- a fibrous material treated according to the method of the invention. Also included are fabrics or textiles incorporating fibres when treated according to the method of the invention.
- reaction product which is believed to have the average formula wherein R' denotes
- a bath was prepared with a 2.77% solution in perchloro ethylene of the reaction product prepared in Examples 1 to 5 in which a piece of polyester cotton (65/35) was treated by padding. The piece was heated to 110°C for 1 minute, followed by 2 minutes at 180°C after treatment. The piece had picked up 0.5% by weight of the reaction product.
- reaction product which is believed to have the average formula wherein R' denotes
