The present disclosure relates to napkins, and more specifically, to a biodegradable napkin having skin care and healing properties.
BACKGROUND
[0002] Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the
information provided herein is prior art or relevant to the presently claimed
invention, or that any publication specifically or implicitly referenced is prior art.
[0003] The menstrual wastes in India alone are projected to be 90000 tons
annually, it is a global problem (77 million tons) and most of the countries do not
know or could not find the better ways to handle these huge piles of wastages.
The fact is ignored comfortably that the raw materials used in making most
sanitary products are assumed to be only cotton and plastic. The sanitary products
are more than 90 percent plastic with super absorbent polymers and non-woven
plastic components; it is extremely difficult to naturally degrade these wastages.
In general the napkin wastages are thrown in sewage systems, landfills, fields and
water bodies, these wastages create a big environmental and health risks. This
will be a big issue and it will take 100s of years to naturally degrade, these non-
bio degradable wastages are just left without any recycling.
[0004] Clearance of soiled non-biodegradable diapers, which gives out
offensive smells and harbor pathogenic organisms, contribute to environmental pollution. Further, these wastages contribute to the accumulation of garbage. Landfills and other means of garbage disposal can no longer manage with the escalating amounts of garbage that accumulate as the number of disposables used in our society grows. For these reasons, a non-biodegradable disposable product is undesirable if a biodegradable product having similar properties is available.

[0005] However, commercial sanitary napkins create hazards due to its
chemical contents such as dioxin, furan, pesticides and other endocrine disrupters, apart from that the fact is these wastes cannot be recycled; the collectors of these wastages will have serious health issues. Further, a plastic layer of the disposable sanitary napkins that is used to make stain-free and chemicals used in producing it get transferred between soil, water and air. Furthermore, the other problem is the disposable sanitary napkins rashes created while wearing it for longer hours and some skin diseases and inflammations are very common in these modern napkins.
[0006] Therefore, there exists a need of efficient, effective or improved
biodegradable napkins with skin care and healing properties. Further, there is a need of a bio degradable napkin which gives a coolant effect when worn and cures the skin diseases without any side effects.

such as a creation of a completely bio degradable napkin, this napkin is having
healing properties of skin diseases and gives a cooling effect when it is worn. The
main pulp is made from the rice/wheat straws, these straws are the crops wastes
which are burnt in the open air and creates a huge problems to the environment
and releases the greenhouse gases. This problem is completely solved since the
straws are the main ingredient of this bio-degradable napkin.
[0034] One of the present invention's primary purposes is to safeguard the
environment. The rapid filling of landfill sites with non-biodegradable plastics used in the conventional disposable nappy is a huge threat globally. Most mothers are concerned about global warming and the environment, yet our present lifestyle demands a product that assures convenience as well as safety for babies and the planet. The present invention meets all the above objectives and is 100% biodegradable.
[0035] The conventional three types of napkins are available in market
but proposed processing method has the following advantages
1. The Jute is processed well to give the soothing effect and the final quality will be very soft which will not create any itching to the skins.
2. The anti-bacterial elements are added to protect users from unwanted side effects.
3. The inner covers are coated with Aloe Vera and Wrightia tinctoria to cure the skin diseases and give the cooling effects.
4. The covers are well protected to absorb more and not to leak them outside.
5. It is completely a new concept and reduces the non bio degradable napkin wastages.
6. The rice/wheat straws are the main ingredients which are available abundantly, and we protect the environment by using these to create the bi products.

[0036] Therefore, there exists a need of an efficient, effective or
improved an internet a biodegradable sanitary napkin with skin care and healing
properties. Further, there is a need of a bio degradable napkin which gives a
coolant effect when worn and cures the skin diseases without any side effects.

(Azadirachta indica), and Wrightia tinctoria leaves. To make anti-bacterial and
anti-fungal properties, a mixture of silver (Ag) nano-particle and Neem
(Azadirachta indica) along with Wrightia tinctoria leaves can be used. Simple,
the Neem and Wrightia tinctoria extract can be added with silver nitrate salt by
adjusting pH 7 ~ 8. After complete reactions the Ag-nano-particles can be
separated by centrifuge. Finally, this Ag-nano-particle can be added with Neem
and Wrightia tinctoria extract. This supernatant mixture can be added with after
pathogen removal and freeze dry to make softy porous paper mold.
[0051] In another embodiment, the covering layer (6) can be formed of
lignin free detoxified jute fiber cloth that is retrieved from treatment of jute cloth with sodium sulfide and sodium hydroxide, hydrogen peroxide in presence of bleach powder. The jute fiber processing includes: the jute fiber cloth can be used as a body of the diaper. Before making the cloth the jute fiber can be treated with sodium sulfide and sodium hydroxide to remove the lignin and soft towards to cotton. Finally, the jute fiber can be treated with hydrogen peroxide in presence

of bleach powder and lignin free detoxified jute fiber can be generated. The fiber
can be used to make jute-cloth, which can be used as a body of the diaper.
[0052] In another embodiment, the proposed biodegradable sanitary
diaper is very cheap since the raw materials are available at free of cost / minimal cost since things are taken from crop wastes. The processing cost will be there but in mass production it will be less.
[0053] In another embodiment, Wrightia tinctoria and neem (Azadirachta
indica), these two herbs can have good skin care properties. The proposed lignin removal method that removes all complex organic polymers from the rice and wheat straw, this process makes the paper pulp as a complete organic free material that can avoid microbes growth.
