Abstract
A deodorant fibrous material contains (1), as a first deodorant material, at least one deodorant component selected from inorganic type and polyorganic acid, ester or salt type components, (2), as a second deodorant material, at least one of a hydrazine compound and a specified polyvinyl amine compound and (3) a synthetic resin binder. The deodorant fibrous material can be produced by applying to a fibrous material, by a padding or coating method, a liquid composition containing the above components (1)-(3), followed by subsequent heat treatment.
Claims17
A deodorant fibrous material comprising a fibrous material having a surface to which is attached a deodorant composition comprising:
- (1) a first deodorant material selected from at least one of an inorganic component, a polyorganic acid component, a polyorganic acid salt component and a polyorganic acid ester component said inorganic component providing at least one inorganic element;
- (2) a second deodorant material comprising a polyvinyl amine compound of the formula:
- ##STR2## wherein R is a group selected from CHO, and CH.sub.3 CO groups, n is an integer between about 150-4,650, m is an integer between about 0-150;
- and
- (3) a synthetic resin binder.
A deodorant fibrous product formed from a deodorant fibrous material comprising a fibrous material having a surface to which is attached a deodorant composition comprising:
- (1) a first deodorant material selected from at least one of an inorganic component, a polyorganic acid component, a polyorganic acid salt component and a polyorganic acid ester component;
- (2) a second deodorant material comprising a polyvinyl amine compound of the formula:
- ##STR3## wherein R is a group selected from CHO, and CH.sub.3 CO groups, n is an integer between about 150-4,650, m is an integer between about 0-150;
- and
- (3) a synthetic resin binder.
A method of producing a deodorant fibrous material, which method comprises applying to a surface of a fibrous material a liquid deodorant composition comprising:
- (1) a first deodorant material selected from at least one of an inorganic component, a polyorganic acid component, a polyorganic acid salt component a and polyorganic acid ester components said inorganic component providing at least one inorganic element;
- (2) a second deodorant material comprising a polyvinyl amine compound of the formula:
- ##STR4## wherein R is a group selected from CHO, and CH.sub.3 CO groups, n is an integer between about 150-4,650, m is an integer between about 0-150;
- and
- (3) a synthetic resin binder, and thereafter subjecting the fibrous material to heat treatment.
