DRYING-AID FOR LAUNDRY
Provided are drying aid compositions, which comprise an ethylene oxide-propylene oxide-ethylene oxide (EO/PO/EO) triblock copolymer and an aminosilicone. The compositions can be added to the aqueous bath during the laundry process to reduce the drying time of a textile. Also provided is a process for laundering a textile, which comprises contacting the textile with an aqueous bath containing a drying aid composition comprising an ethylene oxide-propylene oxide-ethylene oxide (EO/PO/EO) triblock copolymer and an aminosilicone.

34 . A process for laundering a textile, the process comprising:
A) contacting a textile with an aqueous bath;
B) separating the textile from the aqueous bath; and
C) drying the textile,
wherein the aqueous bath comprises from about 0.05 g to about 10 g of an ethylene oxide-propylene oxide-ethylene oxide (EO/PO/EO) triblock copolymer per kg of textile;
and about 0.01 g to about 7.5 g of an aminosilicone per kg of textile.
35 . The process of claim 34 , wherein the EO/PO/EO triblock copolymer has a molar mass of from about 500 g/mol to about 5000 g/mol.
36 . The process of claim 34 , wherein the EO/PO/EO triblock copolymer comprises a PO block having a molar mass of from about 450 g/mol to about 4500 g/mol.
37 . The process of claim 34 , wherein the EO/PO/EO triblock copolymer comprises from about 1% by weight to about 25% by weight EO.
