Degradable sanitary napkin for women

Abstract

The invention discloses a degradable sanitary napkin for women, belongs to the field of hygienic products, and provides a degradable sanitary napkin for women. The sanitary napkin is characterized in that a degradable bottom film is prepared by adopting a full-degradable film blowing / blow molding process; the degradable bottom film is composed of thermoplastic biodegradable plastic and polylactic acid; a wood pulp absorption core is made of plant cellulose extracted from wood; a macromolecular water absorption layer is made of a degradable macromolecular material; and a small coating layer is made of a degradable material. The organic cotton layer and the organic cotton separation edge layer are both made of 100% organic cotton, and the advantages of being ecological and environmentally friendly are achieved; the degradable bottom film, the small coating layer and the macromolecular water absorption layer are degraded into carbon dioxide and water at the fastest speed of 3-6 months at normal temperature; and a wrapping layer and a back pasting layer are made of paper materials made of plant fibers, the wood pulp absorbing core is made of plant cellulose extracted from wood, and 100% of the three layers of materials can be naturally biodegraded.

Description

technical field [0001] The invention belongs to the field of sanitary products, in particular to a degradable sanitary napkin for women. Background technique [0002] A woman needs a total of 10,000-20,000 sanitary napkins in her lifetime; discarded sanitary napkins are dry garbage, and traditional sanitary napkins are mainly made of cotton, non-woven fabrics, pulp, or polymers and polymers formed from composites of the above materials. Polymer composite paper cannot be recycled after it is used up; therefore, discarded sanitary napkins are one of the most difficult solid wastes to dispose of. The main absorption component of traditional sanitary napkins is polymer water-absorbent resin, which is equivalent to plastic to a certain extent. There are no enzymes that can decompose it in the biological world, so it can only be solved by incineration, which will inevitably cause environmental pollution and even harm to the human body; at the same time, other components of traditi...

[0002] A woman needs a total of 10,000-20,000 sanitary napkins in her lifetime; discarded sanitary napkins are dry garbage, and traditional sanitary napkins are mainly made of cotton, non-woven fabrics, pulp, or polymers and polymers formed from composites of the above materials. Polymer composite paper cannot be recycled after it is used up; therefore, discarded sanitary napkins are one of the most difficult solid wastes to dispose of. The main absorption component of traditional sanitary napkins is polymer water-absorbent resin, which is equivalent to plastic to a certain extent. There are no enzymes that can decompose it in the biological world, so it can only be solved by incineration, which will inevitably cause environmental pollution and even harm to the human body; at the same time, other components of traditional sanitary napkins are mostly refractory or non-degradable materials; The scent of sanitary napkins uses flavor enhancers or other chemicals to cover up the scent. If it is used for a long time, it will not only have no soothing effect, but will easily cause allergies or inflammation; therefore, it is urgent to develop biodegradable sanitary napkins for women.
