after heating for ten minutes at 120 u00b0 c the fabric samples were washed and air dried an add on of 18 0 and an efficiency of conversion of monomers to polymer of 67 6 was obtained a treating solution containing 15 thpc 15 bvp 15 acrylamide 10 tmm and a trace of wetting agent was prepared knit fabrics were immersed in this solution padded to 115 140 wet weight gain and placed on pin frames fabrics were dried 4 minutes at 85 u00b0 c and cured four minutes at 150 u00b0 c the samples were washed in hot tap water and air dried the results obtained are shown below table vi______________________________________type of fabric treated fabriccotton polyester add on efficiency char length in ______________________________________100 0 56 0 73 3 2 880 20 59 4 75 3 2 530 70 48 4 69 1 3 8 0 100 44 6 69 9 4 8______________________________________ the treated fabric samples were subjected to extraction with hot tetrachloroethylene no significant weight losses were observed char length of the extracted samples were unchanged from the lengths obtained originally except in the case of the 100 polyester fabric which gave a char length greater than 5 inches after extraction a series of cotton polyester knit fabrics was immersed into a solution containing 15 thpc 15 bvp 15 nma 5 urea 1 mba 0 1 ethylenediaminetetraacetic acid and a trace of wetting agent after padding to 100 130 wet weight gain samples were treated as in example 20 results are summarized below table vii______________________________________type of fabric treated fabriccotton polyester add on efficiency char length in ______________________________________100 0 42.
