Description:
NATURAL ABSORBET CORE INVENTION History The present invention relates to a bio degradable hygiene product that could be used in baby diapers, sanitary pads, adult diapers, baby pads, breast pads, and all other single used hygiene products. The present construction will bio degrade under aerobic conditions within a period of time which is less than 24 months. The importance of this product is due to the concerns of global warming and toxins to land fill while they also clog septic pipes. Such conditions in the US as well as the world accounts to over US$ 50, million in the USA to clear sewage on an annual basis. The present invention will also give choices to the consumer to make smart changes in hope of contributing to a global need. Understanding the natural physical properties of fibre the present invention is related to constructing a product that could break down and reduce the stress on land fill and also on the environment. The construction of the layers wh ich will support its' physical properties to marry each other and demonstrate a perfect product in terms of comfort, softness, flexibility, reliability, safe, and environmentally friendly at the final outcome of the life of the product. There are many companies that are developing new products new technologies and trying to make a difference which is remarkable and having researched many of them in this present invention, we address the most important features that we have achieved with scientific evidence to structure a ecofriendly and a baby safe product. In the present invention we will describe layer to layer of it's construction which will allow the patent to be read clearer and understand the construction to any layperson as we find that at the examinations some of the questions raised, seem that it could be difficult for some to understand the description and therefore the full document is detailed for a better understanding of the present invention. Description The baby diaper in this instance has several layers and comprises of all these components to make it a final product the Baby disposable diaper. The layers are, outer cover, liquid impervious layer, the absorbent pad which is viscose fluff (regenerated natural fibre, viscose is carded to make fluff), SAP(Supper absorbent polymer) Collagen (Gelatine powder) Agar powder (Made up of sea weed) wrapped in tissue paper which forms the absorbent core, the Acquisition layer which is the second layer just under the adjacent layer to the body,( the top sheet) which is next to skin, with the cuff on either side to prevent leakage, elastic for legs and back, frontal tape and Velcro fastening which will be detailed in the drawings. (Please Note that the elastic and frontal tape and Velcro are accessories to the product) The nonwoven fabrics that the present invention comprises is 1 00% cotton as the outer cover . The cuff and top sheet, made up of PLA Poly Lactic acid derived from fermentation of corn. The nonwoven fabrics in the diaper are the back sheet, top sheet, cuff. All of these materials are Natural. The viscose fluff in the absorption is regenerated by man to develop the fibre which is carded and made into a fluff. The production of non woven is a process that can be in three different ways, which is parallel laid, cross laid or entangled. In this instance we use the parallel laid non woven of PLA fabric which is commercially described as.(Nonwoven is also called needle felted) The absorbent core which could be used in baby diapers/ adult diapers or sanitary pads, or any type of pads which are single use disposable products will comprise in this present invention as a blend of Gelatine powder (highest quality made in Australia) Agar agar the sea weed powder which we use for lab work and a very minute percentage of super absorbent polymer which is minimum in grams. The reason for the use minute percentage of of SAP (supper absorbent polymer) in the present invention is to prevent the natural powders of Gelatine and or Agar Agar powder, from contamination, fungi. This is the only reason to include very small percentages of SAP (Supper Absorbent polymer) in the absorbent core of the present invention The liquid impervious layer which is made up of TDPA (totally degradable plastic) additives that comprises of a degradable plastic, which in the presence of oxygen, sun and stress will break down to tiny particles which helps the micro organisms to absorb at this level. The other accessories of the product will be the elastic tape, frontal tape which is of a design and the Velcro tapes and the back waist elastic which are all non-bio degradable and considered as accessories of a product. In the present invention we will describe in the drawings the main body of the baby diaper which we have developed through in-depth research, invented by a fibre specialist/scientist and will claim novelty and the inventive method of a bio degradable 90%natural absorbent product. Description related to the drawings: The outer cover marked as NO 1 in the drawings of the product diaper/pad will comprise of a 100% cottoon non woven which is also known as needle felted. The fabric will be used as the outer layer and will be made up of cotton fibre. The weight of this fabric is in the range of 20 -25 gms per square meter in weight. The liquid impervious layer: marked as NO 2 (water proofing layer) in the drawings. The liquid impervious layer is developed incorporating EPI'sTDPA (Totally degradable plastic additives) Disposed in landfill it will degrade in the presence of oxygen, heat and stress within 12 to 24 months. Even in inadvertently littered, it will degrade in the presence of sunlight and wind, and ultimately bio degrade when exposed to oxygen, soil, moisture and microbes as described in ASTM D 6954 -04 Top sheet marked as NO 3 in the drawings; The top sheet is made up of PLA non woven which is derived from fermentation of corn. The material is needle felted non 77 woven and weigh 15-25 gms. The material will bio degrade in landfill in aerobic or

78 anaerobic conditions. The material will break down if it is inadvertently littered. A natural

79 product that will bio degrade into the carbon cycle. so Cuff marked as NO 4 in the drawings; The cuff in the product is to control overflow and

81 to fit at the leg. It has 3 inserts of baby elastic when it is used in diapers. The cuff is

82 made of PLA non woven which is derived from fermentation of corn. The material is a

83 needle felted non woven , weigh 17-25 gms in weight. The material will break down in

84 aerobic or anaerobic conditions and will bio degrade into the carbon cycle.

85 Liquid Impervious Layer (ACQ) marked as No 5 in the drawings; The ACQ layer is to

86 prevent backflow of body fluids to the surface. It is placed under the top sheet and above

87 the absorbent pad. The body fludis flow from the top sheet through the ACQ layer and

88 then to the absorbent pad. It does now allow to back flow to the top. The ACQ is placed

89 at the centre of the pad. The material used for the pad is non woven parallel laid and it

90 is a polyester mix non woven (needle felted). The weight of the fabric is from 5 gsm -

91 25gsm. The ACQ material will degrade and break down to very small particles, in the

92 presence of oxygen, heat and stress and moisture.

93 The absorbent core pad marked as NO 6 in the drawings. The absorbent pad consists

94 of tissue paper as the overall wrap of the absorbent core. The core is filled up in the

95 process of state of the art manufacture by a spray jet which is a mixture of viscose fluff,

96 gelatine fine power and 1 -3 gms of SAP (supper absorbent polymer) and or Agar

97 powder, viscose fluff and 1 -3 grams of SAP (super absorbent Polymer) in the structure

98 of baby disposable diapers. This will absorb body fluids which are urine and faeces. The

99 top sheet which is No 3 will be the overall wrap of the absorbent core. The usage of

100 gelatine powder and Agar powder and SAP will vary according to the use of products in

101 the Hygiene product range which is, Baby disposable diapers, absorbent pads, sanitary

102 pads, adult incontinence pads, maternity pads, breast pads adult incontinent diapers,

103 pet diapers, chair and bed protectors. This combination of ingredients is novel and

104 inventive.

105 Accessories which is not included in the invention are the frontal tape designed

106 according to branding, Velcro fasteners, back elastic and leg elastic. These come under

107 accessories to a product which will not be included as part of the invention.

108 Invention; In the present invention which is the overall product the choice of materials

109 understanding the physical properties of each individual material used and structuring it no together to perform as a high percentage of a bio degradable hygiene product is aimed in to comply with ASTM/AUS/EU standards for bio degradability.
