Claims
- 1. In a continuous leather manufacturing process for treating hides by non-sequentially tanning, pretanning and/or retanning with chromimum or aluminum electrolyte-containing liquors, fatliquoring, and other known chemical processing steps, the improvement comprising using a fatliquoring agent which is stable in the presence of said electrolyte-containing tanning liquors, and wherein said tanning liquors and said fatliquor are at least partially associated with one another by adding said fatliquoring agent to the tanning or retanning liquor before, during, or after the addition of the chromium or aluminum electrolytes, so that said agent and said electrolytes are simultaneously present, said fatliquoring agent comprising

- (3) C.sub.12-18 alkyl sulfosuccinate, sodium salt;
- (4) C.sub.12-24 fatty acid (+3 E.O.) sulfosuccinate, sodium salt; or
- (5) C.sub.12-18 fatty acid (+2 E.O.) sulfosuccinate, sodium saalt.
- 6. The process of claim 1 wherein (B) is at least one of:
- (1) C.sub.16-18 fatty alcohol+20 E.O.;
- (2) nonyl phenol+10 E.O.;
- (3) nonyl phenol+9 E.O.;
- (4) C.sub.12-18 fatty alcohol (+5 E.O.) sulfate, sodium salt; or
- (5) C.sub.12-18 fatty acid monoethanolamide (+2 E.O.) sulfate.
- 7. The process of claim 5 wherein (B) is at least one of:
- (1) C.sub.16-18 fatty alcohol+20 E.O.;
- (2) nonyl phenol+10 E.O.;
- (3) nonyl phenol+9 E.O.;
- (4) C.sub.12-18 fatty alcohol (+5 E.O.) sulfate, sodium salt; or
- (5) C.sub.12-18 fatty acid monoethanolamide (+2 E.O.) sulfate.
- 8. The process of claim 1 wherein ingredient (A) is present in about 50 to 85% by weight.
- 9. The process of claim 2 wherein ingredient (A) is present in about 50 to 85% by weight.
- 10. The process of claim 3 wherein ingredient (A) is present in about 50 to 85% by weight.
- 11. The process of claim 7 wherein ingredient (A) is present in about 50 to 85% by weight.
- 12. The process of claim 1 wherein said agent is used in a total quantity of about 0.1 to 6.% by weight based on the total weight of said hides.
- 13. The process of claim 3 wherein said agent is used in a total quantity of about 0.1 to 6.% by weight based on the total weight of said hides.
- 14. The process of claim 7 wherein said agent is used in a total quantity of about 0.1 to 6.% by weight based on the total weight of said hides.
- 15. The process of claim 1 wherein said agent is used in a total quantity of about 0.5 to 4.% by weight based on the total weight of said hides.
- 16. The process of claim 3 wherein said agent is used in a total quantity of about 0.5 to 4.% by weight based on the total weight of said hides.
- 17. The process of claim 7 wherein said agent is used in a total quantity of about 0.5 to 4.% by weight based on the total weight of said hides.
- 18. The process of claim 2 wherein said tanning liquor electrolytes are at least aluminum or chromium.
- 19. The process of claim 7 wherein said tanning liquor electrolytes are at least aluminum or chromium.
