Abstract
Low molecular weight silicone polyether ABA type block copolymer treatments wherein a linear polysiloxane is terminated at each end by a polyether moiety derived from ethylene oxide are useful to imparting a hydrophilic coating to the surface of either woven or non-woven textiles.
Claims10
A polymeric fabric treated with a silicone compound selected from the group consisting of:
- 1) polysiloxane polyethers having the formula:
- where R1 is selected from the group consisting of hydrogen and alkyls and R2 and R3 are each independently selected from the group consisting of one to forty carbon atom monovalent alkyl radicals;
- the subscript a ranges from about 1 to about 8;
- the subscript b ranges from about 1 to about 10;
- the subscript c ranges from zero to 2;
- the subscript d ranges from about to 1 to about 10;
- and the number average molecular weight ranging from ranges from about to 300 to about 1,000,
- whereby said fabric is rendered durably hydrophilic.
