Abstract
A combination of two separate compositions used for cleaning natural fibers and fabrics made therefrom and the method of using same. The first composition provides for low temperature washing of the fibers and contains two different non-ionic surfactants and an anionic surfactant in the ratio of about 3:1 and 1:3 respectively. The composition for the rinse cycle is between about 1 and 3 percent by weight of at least one non-ionic surfactant and between about 15 and 25 percent by weight of a cationic surfactant.

A composition for the treatment of natural fibers comprising:
- a natural fiber washing composition comprising non-ionic surfactants and anionic surfactants in the ratio of about 3:1 and 1:3 respectively;
- there being at least two nonionic surfactants having different molecular structures in said composition, each having a hydrophilic/lipophilic balance (HLB) value between about 0 and 20, and there being a difference in said HLB values of said nonionic surfactants in said composition of at least 2;
- said nonionic surfactants being present in the ratio of about 1:2.
A composition for the treatment of natural fibers comprising:
- a natural fiber rinsing composition comprising between about 1 and 3 percent by weight of at least one non-ionic surfactant and
- between about 15 and 25 percent by weight of a cationic surfactant having the formula:
- [R2(OR3)]y[R4(OR3)y]2 R5 N+X−
- wherein R2 is an alkyl or alkyl benzyl group having from about 8 to about 18 carbon atoms in the alkyl chain,
- each R3 is selected from the group consisting of —CH2CH2——, ——CH2CN(CH3)——, ——CH2CH(CH2OH)——, ——CH2CH2CH2——, and mixtures thereof;
- each R4 is selected from the group consisting of C1-C4 alkyl, C1-C4 hydroxyalkyl, benzyl ring structures formed by joining the two R4 groups, ——CH—CHOH——, CHOHCOR6CHOHCH20H wherein R6 is any hexose or hexose polymer having a molecular weight less than about 1000, and hydrogen when y is not 0:
- R5 is the same as R4 or is an alkyl chain wherein the total number of carbon atoms of R2 plus R5 is not more than about 18;
- each y is from 0 to about 10 and the sum of the y values is from 0 to about 15:
- and X is any compatible anion.
The composition for the treatment of natural fibers as defined in claim wherein said nonionic surfactant in said natural fiber rinsing composition has an HLB value in the range of between about 8 and 14.
A method for the washing and rinsing of natural fiber comprising:
- washing said natural fiber by contacting said natural fiber with
- a natural fiber washing composition comprising non-ionic surfactants and anionic surfactants in the ratio of about 3:1 and 1:3 respectively;
- there being at least two nonionic surfactants having different molecular structures in said composition, each having a hydrophilic/lipophilic balance (HLB) value between about 0 and 20, there being a difference in said HLB values of said nonionic surfactants in said composition of at least 2;
- said nonionic surfactants being present in the ratio of about 1:2 then
- rinsing said washed natural fiber with a rinsing composition comprising
- a natural fiber rinsing composition comprising between about 1 and 3 percent by weight of at least one non-ionic surfactant and between about 15 and 25 percent by weight of a cationic surfactant having the formula:
- [R2(OR3)]y[R4(OR3)y]2 R5 N+X−
- wherein R2 is an alkyl or alkyl benzyl group having from about 8 to about 18 carbon atoms in the alkyl chain,
- each R3 is selected from the group consisting of —CH2CH2——, ——CH2CH(CH3)——, ——CH2CH(CH2OH)——, ——CH2CH2CH2——, and mixtures thereof;
- each R4 is selected from the group consisting of C1-C4 alkyl, C1-C4 hydroxyalkyl, benzyl ring structures formed by joining the two R4 groups, ——CH—CHOH——, CHOHCOR6CHOHCH2OH wherein R6 is any hexose or hexose polymer having a molecular weight less than about 1000, and hydrogen when y is not 0:
- R5 is the same as R4 or is an alkyl chain wherein the total number of carbon atoms of R2 plus R5 is not more than about 18;
- each y is from 0 to about 10 and the sum of the y values is from 0 to about 15:
- and X is any compatible anion.
