UL Flushable Cellulosic Products and Processes and Apparatus for Flushing Such Products Full Description BACKGROUND The present invention relates to the field of cellulosic articles, such as hand towels, napkins, pre-moistened slate towels, wipes and similar items disposed of in toilets and sewage networks. 0 The cellulosic tools used for personal care, such as toilet papers, hand towels, pre-moistened tissues, small towels and other spaces, are disposed of by throwing them into toilets and sewage networks. Most toilet papers are made to be thrown into the toilets because they are composed of cellulosic materials with minimal moisture resistance. Toilet and toilet papers are exposed to crumbling and dispersing easily 0 once they are shaken with the water in the toilet and the traditional sewage network. These wipes are not designed for use in cases where the wipes collide with basic liquids during use. Hand towels, napkins, small towels, and wipes (AY) are generally much stronger than toilet paper;, They are composed of cellulosic materials in a way that gives Vo enough resistance when wet so that it can be used for multiple purposes such as drying Gua and drying the buttocks of young babies pala aly liquid spills. Surface cleaning, etc. Toilet papers are generally considered unsuitable for such uses due to their poor resistance.

. Paper towels, wipes, and slate towels sometimes cause a problem when they are flushed through a conventional toilet grate, due to their added resistance. .?A minute or more to reach the level of moisture resistance that can be flushed.The accumulation of such products leads to clogging of sinks and toilets.The term “flushable” refers to the ability of the product to be flushed in a conventional toilet and pushed into the municipal sewage network or a network that collects rotting residential waste without causing Obstruction or blockage in the toilet or sewage network. The scavenging products include 0 products in which dispersion occurs in the cellulosic strand constituting the paper product due to the decomposition of the binders; In addition to products whose dimensions are not limited to transport through the pipeline without clogging. The term “pala a” as used in this paper refers to traditional toilets as well as plumbing fixtures that are connected to the sewer network such as No urinals, basins, etc. Paper towels and the like are flushable in traditional toilets. Like all toilet paper tissues; and unlike the anal dL tissue paper, these flushable paper products must have a sufficient degree of resistance for the use for which they are intended; which is described as dale on absorbing liquids and wiping part of the Body parts or any other surface In the past, an attempt has been made to design wipeable products, and the focus has been on making wipeable tools such as baby diapers, baby care products such as training pants, and adult care products such as adult diapers and incontinence pads

For adults, feminine pads, wound dressings, household wipes, cloths, tapes, tampons, etc., which are dispersed upon contact with ordinary tap water. In US Patent No. 00.8417 such flushable devices are detected in ordinary toilet and sewer water at temperatures less than about YY degrees an pia, but are insoluble in the presence of bodily fluids at temperatures greater than Approximately YO is a residual degree. Attempts were also made to make small, ready-to-use disposable towels that are dispersible in water. For example, in US Patent No. 101777 0 a small pre-moistened towelette comprising a binder of polyvinyl alcohol that is packed wet in a solution containing borate ions and bicarbonate ions was disclosed. The small towel retains a certain degree of moisture resistance when packed, and during at least part of its use, but disperses in water. US Patent No. AIT 0 discloses the use of Vo-moisture-resistant resins, in paper products that maintain adequate moisture resistance only temporarily (therefore they are called “temporary moisture-resistant agents). Disclosure of a non-woven braid with enhanced moisture resistance and the ability to be easily disposed of in Un with a high pH number and the invention explains the uses of the pH sensitive binder in the formation of Y. The braid that is dispersed at a high pH number Some work has been done Thin fabrics and films that show water-repellent properties, which are dispersed in some solutions, and are lubricated by those solutions.For example, JULI in US Patent No. 2.3908 discloses a polymeric composition with

0 An interfacial cross-linked polymer of silane, which gives water retention properties to the resulting thin films. Thin films are soluble in alkaline or acidic aqueous solutions having a HCl number of about 11 or higher or about ? or less . US Patent No. 8474.74 discloses a thin film material to make 0 a disposable toiletry item, such as a bag for body waste products 0, which is unaffected by contact with neutral pH water; But it decomposes in contact with an alkaline solution that is added to the toilet bowl. As is the case in the fabrics discovered in US Patent No. 1.7008, this material is resistant to liquid, and can be used, for example, JBL, in the composition of non-water permeable tools, Jia mattress linings, and disposable bags. . US Patent No. 851171707 discloses an orifice bag composed of a pH-sensitive material that is soluble when exposed to an aqueous liquid in a toilet in which the pH is EL or less than the level of a neutral Hyder-Gene number. No. US Patent No. 547.987 relates to the formation of tools such as bags for surgical openings, wound dressings, bandages, diapers, etc.; Which can be done as a simba by wrapping or surrounding the tool inside a material that becomes sticky when in contact with water or secretes a sticky substance when in contact with water in the base of the toilet or Lalas such materials directly to the base of pala ll and no dispersion occurs in these tools Yu sc From that, it is lubricated or.? Lubricate it to ensure that the tool passes through the pipe network. Dispersible toilet products that are pH-dependent are well known; Despite that; Many Jie of these products are impermeable to water, in contrast to the water-absorbent products

+ of the present invention. Most of the dispersible paper products used in the toilet and similar to the products of the present invention are tissues that are dispersed once they are shaken with water in the toilet / sewer network. GENERAL DESCRIPTION OF THE INVENTION 0 The present invention relates to a device such as a hand towel 1 or a wet wipe, or a whistle towel or Lalas that can be flushed in a conventional lavatory network in contact with an external gall material. The present invention also relates to a flushing device that allows the paper product to be flushed in a conventional toilet network without the need for human intervention. 0 The present invention also relates to a flushing device that allows the paper product to be flushed in a conventional toilet network after adding an extra external substance. The present invention relates to a process for scavenging a paper product by adding an additive to a conventional toilet net which allows the paper product to disperse sufficiently to make it scavenger. Vo These and other purposes are achieved by finding a sufficiently dispersible paper device in a traditional toilet network when additional material is added to the network. In addition, these and other purposes are achieved by finding a way to flush a paper product in a traditional toilet network by adding an additional external substance to the network. These and other purposes are finally achieved by finding a scavenging device in which a substance is added.| In addition to the traditional sewage network to disperse the paper product when it comes into contact with the outer adhesive material. The external additive required to start the process of dispersing the paper product can be 0

Vv for example JUL, is a chemical agent that adjusts the pH of flushing toilets, or an enzyme that attacks the starchy bale or other binding agent in the paper product; or a salt that loosens the polymer binder used in the paper product; Or a halogen-containing compound that attacks the polyamide resin - epichlorohydrin oo used in the paper product. The extra charge may also include ultrasonic vibrations or electric currents that help disperse the paper product once it is thrown into the toilet bowl. One of the advantages of the present invention is that products made of cellulosic strands, such as towels and washcloths; Which is absorbent and stretchy if it is dry or ale

Cobol for moisture if it was previously moisturized; It can have a sufficient resistance rating of 0 to serve wiping purposes, while still being scavenged to prevent clogging of the mesh. When it is disposed of, which is the ability of one of the manufacturers to find a specific product 0 There is another feature of the present invention that works with a specific adding device. For example JBL, a dispersible paper product 1 can be made to work with a special additive so that it becomes the special chemical additive or additive sold by paper product makers; It becomes the only means for the collapse of the paper product of these makers. This assures bathroom owners that the paper products they buy are dispersed with high efficiency if they also purchase the appropriate adding device. Y. The present invention can be used in sal cases, avoiding the need for human intervention to remove blockages in toilets or pipes; If an extra external dispersible towel is placed in the pala ll, while in another model, a manual addition of an additional dal dispersion material is performed.

A special series of embodiments of the present invention relates to the exploitation of an additional chemical substance to start the process of dispersing the product, and in one of the embodiments an agent is used to control the degree of alkalinity, and the alkalinity control agent may be an acidic composition or a basic composition that changes the number The pH of toilet base water (or sewer system water) is 0 when it is added to the water. Such a composition includes any alkaline substances such as lithium, sodium, and potassium hydroxides, sodium carbonate solutions, ammonia solutions, calcium or barium oxides, in addition to any of the acids such as sulfuric acid, hydrochloric acid, sodium acid sulfate, potassium acid sulfate, etc. Like. 0 These control agents may contain buffer solutions. The present invention is not limited to the special alkaline or acid composition that is used as an agent to control the degree of alkalinity in this model. The paper product is designed so that it is characterized by the required degree of moisture resistance at a neutral hydrogen and genetic number (Lid) and so that it is dispersed and scavenged when subjected to a change in the degree of alkalinity of the toilet water. It is clear that the degree of alkalinity control must be kept at ial levels to prevent harm to toilet users; Therefore, it is preferable to use the Heider and Gini number close to the degree of parity. More precisely, the binding agents used in the production of such paper products are subjected to dispersion at low or high alkalinity. And in Ula exposure El toilet Y. With the degree of alkalinity modified, the function of the binding agents stops and causes dispersion and dissolution of the cellulosic strands. In another embodiment, an organic binder such as starch or modified starch is used to give the cellulosic strand moisture resistance. Then an additive can be used

\Y Chemical, such as an enzyme, as a factor that stops the function of the binder and disperses the paper product. In another embodiment, a polymeric binder can be used in the composition of the paper product + a corresponding salt can be used to replace or "untie" the polymer. to start the dispersal process

0 A sensitive binder may also be used for some formulations, for example, a polyamide-epichlorhydrin resin, such as Alchemene (patented) (sold by Hercules), may be used to form the product. An additive containing halogen such as hypochlorite may be used as an external starting additive. Surfactants can also be used

The tube can be made with the mentioned distillation mechanisms, including Jal materials from the well-known formulations of the external additive (in addition to wood! The flexible plastic. The output is made with other detergents, deodorizing agents, and the like. ) into the base of the toilet in the pattern shown by a timing mechanism 4. In an alternative method, a photosensitive detector mechanism can be used to regulate the periodic excretion of extraneous matter when toilet users are present. These mechanisms are also well known. In the field, various other well-known models in the field for sending such additional materials include and among these devices. lead) chemical, on various known 0-start autotransmitters; There is a water supply induction device, a flotation mechanism addition device, and a chemical additive injection device. Each of these devices is well known in the field. All of them are part of the current invention. During use, a specific amount of the external additive material is expelled into the base of the toilet. 7; In this way, sufficient quantities of the extra material, 1 Outer J, remain in the base of the toilet to come into contact with any paper products that are thrown into the base. The toilet In an alternative method, the chemical is supplied through a separate distillation device to the toilet, pipe network, or sewer network. In addition, the chemical additives can be supplied in the form of additional materials, each of which is packaged independently (YL), so that it can be added manually before or during each flushing operation performed by the toilet user. The independent packages can be bags containing solid forms of the additive, or a toilet cistern tablet containing the additive.

Syringes, vials, sachets, or other containers containing liquid forms of the additive. The stand-alone packaged additive can also be manually added to the toilet/sewer system after an obstruction has already been formed so that it can be loosened and normal flow force restored. . In another series of models, external forces are replaced by the chemical additives. An example of the aforementioned supercharged forces is the use of ultrasonic vibrations that operate on water in the toilet network, and the binders in the paper product are designed in this model. These additives are JEL so that they are dispersed upon exposure. In an alternative way, an anti-moisture agent may be used in the composition of the product.
