Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
76 words
A composition adapted to treating textiles and non-woven cellulosic products comprising a mixture of a cross-linking agent and a nitroalkanol in an amount of from about 18 to about 142 parts per 100 parts by weight of the cross-linking agent, said nitroalkanol being represented by the formula: ##STR4## where R 2 can be hydrogen, methyl or ethyl and R 3 can be hydrogen or methyl; R 2 and R 3 can be the same or different.
Claim 2
Dependent Claim
76 words
A composition adapted to treating textiles and non-woven cellulosic products comprising a mixture of a cross-linking agent and a nitroalkanol in an amount of from about 18 to about 142 parts per 100 parts by weight of the cross-linking agent, said nitroalkanol being represented by the formula: ##STR4## where R 2 can be hydrogen, methyl or ethyl and R 3 can be hydrogen or methyl; R 2 and R 3 can be the same or different.
Claim 3
Dependent Claim
73 words
A composition adapted to treating textiles and non-woven cellulosic products comprising a mixture of a curable methylol terminated resin and a nitroalkanol in an amount of from about 0.25 to about 3.0 moles per mole of resin, said nitroalkanol being represented by the formula: ##STR5## where R 2 can be hydrogen, methyl or ethyl and R 3 can be hydrogen or methyl; R 2 and R 3 can be the same or different.
Claim 4
Dependent Claim
73 words
A composition adapted to treating textiles and non-woven cellulosic products comprising a mixture of a curable methylol terminated resin and a nitroalkanol in an amount of from about 0.25 to about 3.0 moles per mole of resin, said nitroalkanol being represented by the formula: ##STR5## where R 2 can be hydrogen, methyl or ethyl and R 3 can be hydrogen or methyl; R 2 and R 3 can be the same or different.
