Schaefer
9. Schaefer describes woven, knitted and non-woven
fabrics (col. 1, line 11).
10. One fabric described is a cotton/polyester
knitted fabric.
11. Cotton is a cellulosic material.
12. According to Schaefer, the fabric is treated
with a "medium" comprising (col. 2, lines 5-29):
a. a polysiloxane described as polysiloxane A7
(col. 3, lines 3-29);
b. a polysiloxane described as polysiloxane B8
(col. 3, lines 41 through col. 4, line 30);
and
c. water and/or a water-miscible organic
solvent (col. 2, lines 28-29).
Both patents are prior art under 35 U.S.C. § 102(b).6
Polysiloxane A of Schaefer is apparently the same as, or very similar to,7
applicant's polysiloxane A.
Polysiloxane B of Schaefer is apparently the same as, or very similar to,8
applicant's polysiloxane B.
