DISCLOSURE OF THE INVENTION (Flushing down and referred to as being flushable by a traditional toilet bowl. "In order to effectively produce and cushion and increase the function of absorbing materials, nonwoven fabrics must maintain their structural integrity And when the article is wet or wet, it can show sufficient tensile strength. However, if the nonwoven fabric is exposed to water and becomes dispersed, With almost all of its tensile strength lost, the problem of disposing of this product can be largely eliminated. These materials can then be washed away by a conventional toilet system. Ideally, nonwovens have many characteristics such as Softness and bendability. Weaves are formed by wetting or drying arbitrary fibers into a net shape, and then they are aggregated together to form a bonded fabric. Unfortunately, there are certain uses for providing The characteristics of non-woven fabrics will make the fabrics in water non-dispersed with the previous technology. For example, non-woven fabrics are bonded with a water-insoluble synthetic resin, which will increase the strength in use. However, Such synthetic resin will make the fabric substantially water-insoluble and hinder the scouring of the fabric. As for wet wipes, special problems will arise. This wipe is used for skin cleansing-generally known in the business as a towel substitute, a clear wipe or a female wipe 'all paper or nonwoven fibers treated with a polymeric binder' Fabric. This adhesive will give the fabric some wetting to maintain its tensile strength, but it will be stored in the liver medium of the shirt. However, after the 'wipes are used, the adhesive will gradually lose its effectiveness when exposed to water-like environments such as toilets and toilets without flushing systems. i Paper size applies to China National Standard (CNS) A4 specification (210 X 297 male ------------ Φ- · ^ -----_--- ^ ------- -0 (Please read the precautions on the back before filling out this page) Printed clothing by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy k〇0106 [〇622Ψί ('00 ^ 〇622-2.0οο August 8, 2001 503280 A7

As an example, the adhesive contained in the wipe is an acid-insoluble, alkali-soluble polycarboxylic acid and its functional derivatives, in which an acidic substance is placed in water and sufficient alkaline substance is added. Before the adhesive is added to the fabric with the acid groups substantially neutralized therein. The bonded saturated fabric is dried and then immersed in a low pH vehicle, where the fabric retains its structural integrity, but when the swab is immersed in a liquid vehicle with a high pH, the structural integrity will be destroyed. ~ u Other adhesives used in wet wipes are mixed gels or polyethylene materials such as borax which are not water-soluble. The material will at least cross-link with the surface of the polymeric adhesive before the fabric is allowed to dry to create a waterproof fabric. Such cross-linking is reversible, that is, when the concentration of borax is reduced to a certain degree, the degree of cross-linking is low enough that the adhesive becomes water-soluble. However, boron-containing aqueous solutions are not acceptable for personal care applications due to safety considerations. Other water-dispersible nonwovens utilize water-soluble adhesives with partially neutral unsaturated carboxylic acid / unsaturated carboxylic acid ester copolymers. The problem in this adhesive is that decomposition of the nonwoven fibrous fabric must be avoided before disposal, and the wipes must be maintained in an aqueous solution of pH 値 concentration which causes skin tingling sensations during use. Adhesives containing carboxyl groups are useful in the manufacture of water-dispersible fiber fabrics, that is, at least water-soluble, water-dispersible, or water-decomposable in a water-like environment, resulting in a lack of divalent ions.

Description of the invention (4) The water content in the '4 is' medium hardened, because the aqueous solution It contains divalent ions such as dance ion, so the wipes will not gradually disperse. The existence of so-called divalent ion will make the water-soluble polymeric adhesive roughly become a valley. It is generally believed The reason is that divalent ions will cross-bond with the binder to prevent the binding of Daohuan in water. However, the negative effect of divalent ions is that the solubility of the polymerized binder in the water-like severe environment will be reduced and it cannot be ignored. Similarly, the need for a water-dispersible adhesive composition that can be used in personal care products is necessary. For a wipe, * 口 〇, should be safe to use, and it will also It is affected by the presence of monotonic ions, which are generally found in medium hard water.

After continuous shaking, the hot-rolled polyvinyl alcohol can be cooled to room temperature. The shaking action is continued until some particles of the household are dissolved and the solution is non-gummy. High-cut shear shaking is necessary to ensure that PVA is completely dispersed when added to the water, but is not necessary in the subsequent dissolution step. Additionally, in order to dissolve the polyvinyl alcohol in water, the required amount of polyethylene glycol is added to the water with shaking at room temperature. The shaking motion is continued until the polyethylene glycol is completely dissolved. In this way the time factor is more important than shaking the shears to ensure a complete solution of the gel. In order to prepare a binding solution, the amount of sodium sulfate was dissolved in water, and this solution was added to the polyvinyl alcohol solution with shaking after the addition of the polyvinyl acetate g emulsion. The viscosity of the final bonded composition is about 68 percent poise (cP) ', but such a composition will cause unstable phase separation after a period of stagnation.

Example 6 A fabric containing 31 gsm CEMFIBER® polypropylene (6mm / 2d / f) and Rayonier SSWK pulp (75: 25 weight percent doping) was sprayed with 7 gsm No. 3 adhesive on one side of the fabric with A fabric having a full basis weight of 38 gsm is provided. Just like No. 丨 adhesive, the high viscosity of No. 3 adhesive will hinder the good spray pattern (about 45 °) and cause the adhesive to have poor coverage on the fabric. However, this material has good instant wetting ability, but it is not as good as fabric based on No. 2 adhesive. Example 7 A fabric containing 3 1 gSm CEMFIBER® polypropylene (6mm / 2d / f) and Rayonier SSWK pulp (75: 25 weight percent doping) was sprayed with 7 gsm No. 4 adhesive on one side of the fabric To provide a fabric with a full basis weight of 38 gsm. The second fabric is to reduce its doped fiber basis weight to 27 gsm and spray 3 gsin of No. 4 adhesive on each side of the fabric on both sides of the fabric, which can provide a full basis weight of 33 gsm Fabric. This adhesive will exhibit an excellent spray pattern (90 ° cone angle) and provide better coverage on the fabric. This fabric is also softer to the touch, and this is due to the polyvinyl acetate g-co-ethylene of the No. 4 adhesive. At the same time, it is also obtained from the polyvinyl acetate g of the No. 2 adhesive. Not coarse

Description of the invention (23) Sugar. Like fabrics made with No. 2 adhesive, fabrics made with No. 4 adhesive can allow warm water to penetrate without compromising the integrity of the fabric, but when placed in cold tap water, it will quickly break down. These fabrics are tactilely soft to the driver ’s but do not have sufficient integrity. The polyethyl ether component in No. 4 adhesive is responsible for maintaining integrity in warm water, but can cause the fabric to disintegrate in cold tap water. Example 8 A fabric containing 90 gsm polyester (6mm / 2d / f) and Rayonier SSWK pulp (50:50 weight percent doping) was sprayed on both sides of the fabric with 5 gsm No. 2 adhesive to provide A fabric having a full basis weight of 100 gsm. The fabric made from No. 2 adhesive together with the viscous polyester fiber will produce a fabric with good elasticity, high bulkiness (thickness of 3-4 mm) and low density (0.03 g / cm3). Meets initial requirements for fluid inhalation (burst) materials. After contact with warm water, the fabric can maintain its elasticity and integrity, but will slowly decompose in cold tap water. Polyvinyl acetate in the No. 2 adhesive is responsible for good fabric integrity, but polyvinyl methyl ether can provide a trigger mechanism that causes the fabric to collapse in cold water. Example 9 A fabric containing 90 gsm polyester (6mm / 2d / f) and Weyerhauser NB420 (manufactured by Weyerhauser, Federal Way, WA) fluff pulp (50: 50 weight percent doping) was bonded with size 2 of 5 gsm The agent was sprayed on both sides of the fabric to provide a fabric having a full basis weight of 100 gsm.
