Embodiment Construction

[0028] In a preferred embodiment, the composition of the mixture for application on the printed sheet comprises an aqueous overlay having about 40% to 50% solids, such overlays typically containing polymeric resins, surfactants and additives such as solvents and wax or silicon to create properties like anti-slip and anti-friction. A cover of approximately 3lb to 6lb is applied to each side using a metered size press with a short dwell time, preferably considering the high content of kraft pulp in conventional newsprint which makes the surface of the newsprint very inhomogeneously porous and highly absorbent , leading to performance problems. In the case of difficult substrates, a multilayer cover layer is applied, wherein the pre-cover layer also comprises carbonates and / or surface sizing agents, such as starch. Thereafter, conventional talcum powder is applied to improve the surface properties of the protective layer as well as the covering hygiene sheet. The above covered ...

Abstract

This invention relates to an improved smudge free sanitary sheet made of waste paper and a process of preparing the same through processing the surplus newsprint and mors precisely processing used / recycled paper. The sanitary sheets are prepared by the process steps of collecting pre -consumer overprint or post consumer read newspapers; grading the collected waste newspaper; drying and sterilizing the graded newspaper by applying ultraviolet, infrared and / or gamma rays; trimming and cutting the dried sterilized sheets in appropriate sizes; applying on atieast one of the sides of the waste newspaper an aqueous coating comprising of a mixture of resin such as bleached shellac, a dye, a germicide such as Benzaikonium Chloride (BC) and / or PCMX (Chloroxylenol), a safe colour, a known deodorant and optionally cosmetic chemicals such as emollient and a foaming agent such as a detergent.; The improved sanitary sheeets prepaid by the present cost effective invention has taken care of any toxic effect on human skin to make those hygenic and aesthetic and the discarded sheets being biodegradable, the present invention is environment friendly. The sanitary sheets from present invention has various wide applications such as a single use barrier in outpatient beds of clinics or on x-ray tables, safe paper bags for carrying dry stuff, a mat on a publicly used seat like gyrn, safe pet care , paper towel, toilet paper, sanitary napkin, child diapers, adult incontinence products etc.

Description

technical field [0001] The present invention relates to a sanitary sheet made from waste paper and a method for producing a sanitary sheet by processing surplus newsprint. More specifically, the present invention relates to a method of making hygiene sheets from reused / recycled paper. Background technique [0002] Paper is widely used for hygiene purposes like toilet paper, paper towels, diapers, sanitary napkins and the like. In most of these uses virgin or partially recycled plain paper is used. Since toilet paper is intended for one-time use, a large amount of paper is wasted after such use. Also, most paper used for hygiene purposes is not suitable for recycling. All this leads to the need to provide lower cost and less harmful hygiene papers, keeping the environmental protection in mind, since the paper is made from wood pulp in a very energy intensive process. [0003] In some cases, alternative reusable materials, like fabrics, are used in hygienic conditions, suc...
