touch) related to the product. The product of the present invention is packaged in a moisture impervious container to prevent inadvertent release of the non-aqueous liquid contained therein, and the product is packaged in a moisture impervious container to prevent the non-aqueous liquid contained therein from being encapsulated at the desired time and as desired when the product is moistened with water. Dispensing non-aqueous liquids to perform a variety of functions, such as cleaning, deodorizing, or flavoring surfaces or enclosed spaces, or seasoning foods. The invention also relates to a method for making such a product. products, especially disposable textile products such as tissue paper, cleansing cloths and pads, sanitary towels, powdered products such as abrasive cleaners or talc for absorbing or removing excess body fluids from skin shoulders or spills from other surfaces. The manufacturing industry is an existing industry. Such products are dry but absorbent to mop up body fluids and spillages. The product may also be pre-moistened with alcohol or other suitable solvent (sometimes with fragrance) so that the solvent is distributed during use to facilitate oil removal and deodorization of the applied surface. There is. Such wet products are usually individually packaged in foil pouches or other closed containers to prevent evaporation of the solvent. There has been a long-standing need for a product that is easily packaged, has the ability to dispense solvent or flavoring or other active liquid materials as desired, and is dry-touch, just as the product of the present invention.

(1974) reported that sequential treatment of textile yarns such as rayon with a series of solvents entraps solvents such as carbon tetrachloride in the yarn that are difficult to remove by drying. .
According to a report by Weigmann et al., the entrapment mechanism is related to the reformation of hydrogen bonds between cellulose chains when the hydrogen bond-breaking solvent is replaced with a non-polar solvent that cannot itself break hydrogen bonds. There is. They also found that the cellulose hydrogen bonds are broken again by the introduction of water, releasing trapped water molecules. These findings by Weigmann et al. were the result of textile industry research on the influence of solvents on the mechanical properties and dye diffusion properties of textile yarns. When a product consisting essentially of cellulose or other polymers is processed by solvent exchange methods, a substantially dry-touch product is obtained which is capable of dispensing non-aqueous liquids when moistened with water and has specific effects in use. We have found that this is possible. The present invention is housed in a moisture-impermeable airtight container.
Provides a substantially dry-touch product. The product comprises: (i) a matrix of polysaccharides or proteins or mixtures thereof; and (ii) a dielectric constant of 1.5 to 40 contained in the matrix.
a non-aqueous liquid having a composition, wherein the weight ratio of the non-aqueous liquid to the matrix is from 1:1000 to 1:1, and the non-aqueous liquid is included in the matrix such that it can be liberated when the product comes into contact with water. There is. "Substantially dry-touch product" means a product that does not feel wet to the touch and does not exude water when squeezed. “Included” means that the non-aqueous liquid is physically entrapped within the polysaccharide and/or protein matrix and that the liquid can be liberated when the product is contacted with water or water vapor. do. The matrix of the product of the invention consists of polysaccharides, proteins or mixtures thereof. The polymer has sufficient hydrogen bonding to contain the non-aqueous liquid, which hydrogen bonds are opened by contacting the product with water to liberate the non-aqueous liquid. When the matrix consists of a polysaccharide, the polysaccharide is preferably cellulose or starch.
When the matrix consists of a protein, the protein is preferably keratin or casein. When the matrix is composed of cellulose, the cellulose may be a natural cellulose derived from cotton, flax, wood or other plants, or a regenerated cellulose such as viscose rayon. If it has a sufficient degree of hydrogen bonding to include non-aqueous liquids,
It is also possible to use chemically modified cellulose. If the matrix consists of starch, the starch may be a natural starch derived from, for example, potato, corn or other plants. It is also possible to use chemically modified starches, provided they have a sufficient degree of hydrogen bonding to accommodate non-aqueous liquids. If the matrix consists of keratin, the keratin can be derived from animal wool, such as wool or human hair, for example. If the matrix consists of casein, the casein may be derived from milk. The most preferred polymer making up the matrix is natural or regenerated cellulose. The polysaccharides and/or proteins that make up the matrix can be in the form of yarns or threads, woven sheets, non-woven sheets, sponge-like materials,
Any powder having an average particle size of 10 μm to 1 mm may be used. The non-aqueous liquids included in the matrices of the present invention are liquids with a dielectric constant of 1.5 to 40 (usually measured at temperatures between 0 and 25°C). The dielectric constant of the non-aqueous liquid is preferably less than 40, more preferably 2 to 2.
30, ideally between 2 and 10. An ideal non-aqueous liquid with a dielectric constant of 10 or less is essentially non-polar; the lower the dielectric constant, the less polar it is. It is to be understood that the "nonaqueous liquid" contained within the matrix may consist of a mixture of mutually miscible nonaqueous liquids. If the matrix contains such a liquid mixture, the dielectric constant of this mixture is also between 1.5 and 40 (measured at temperatures between 0 and 25 DEG C.). Examples of non-aqueous liquids are shown in the table below. The dielectric constant of each liquid is also listed.

As described below, the non-aqueous liquid is generally selected depending on the intended use of the product. The non-aqueous liquid may be a solution consisting of an organic solvent and a solute as shown in the preceding table. When the non-aqueous liquid is a solution, the solute dissolved in the organic solvent may be any substance that has special utility at the time of use, ie, at the time of contacting the product with water to release the contained solution. The solute may be liquid or solid at room temperature as long as it is soluble in the organic solvent. Examples of solutes are shown below.

The deodorizing air freshener is patented in U.S. Patent No.
No. 4288341. The amount of solute used in the organic solvent is determined by the solubility of the solute in the solvent and the intended use of the product. The weight of liquid included in the matrix of the product is generally at most the same as the weight of the matrix. The amount of liquid included also depends on the intended use of the product, but generally represents 0.1 to 5.0% by weight of the product. Typically, the amount of liquid included is 1 to 40% by weight, preferably 5 to 30%, more preferably 10 to 25%, ideally 10 to 20%. In view of the fact that the product, in addition to the polysaccharide and/or protein matrix and the liquid included, may also contain other materials, the amount of liquid contained in the matrix is expressed in relative weight proportions. That is, the weight ratio of nonaqueous liquid to matrix is usually 1:1000 to 1:1, preferably 1:1000.
The ratio is from 1:2 to 1:2, more preferably from 1:1000 to 1:3, and ideally from 1:1000 to 1:4. The product essentially consists of a matrix of polysaccharides and/or proteins containing an included non-aqueous liquid. In this case, the product is approximately
It consists of 50-99% by weight polymer and the balance non-aqueous liquid. It is also possible for the product to include non-polysaccharide or non-protein materials such as synthetic polymers such as polyesters, polyamides and polyurethanes. If a blend is used, the product should contain at least 10% by weight of matrix, preferably at least 50% by weight. This is because polymers other than polysaccharides or proteins have almost no ability to contain non-aqueous liquids compared to polysaccharides and proteins. A feature of the product of the present invention is that while remaining substantially dry-touch, the non-aqueous liquid is solidified within the matrix to such an extent that the characteristic odor normally associated with it is almost undetectable. It is included. However, when the product is brought into contact with water, for example during use, the non-aqueous liquid is almost immediately released from the matrix and can be distributed to the appropriate surface or enclosed space as desired. The products of the invention may take the form of, for example, yarns, threads, woven or non-woven fibrous sheets, blocks, sponge-like materials, wool such as cotton wool or animal wool, tablets or powders. Conventional examples of products of the present invention are as follows. Cellulose or wool textile products for hospital, dental, household or cosmetic use, such as absorbents, air fresheners, animal bedding, bandages, toilet bowls, coffee or tea or herb or spice bags,
Covers, bed covers, bibs, bras, work clothes, cushions, curtains, pollution prevention cloth, diapers, diaper covers, drapes, facial tissue, furniture stuffing, costume bags, gauze, handkerchiefs, head supports, coats or dresses or shirts Or suit inner core, pinerest cover, medical towel, napkin, operating room cover, packaging material, padding, petticoat, pillow case, padding or futon side material, protective cloth, quilting, sanitary napkin cover or padding, sanitary Towels, sheets, shirts, insoles, liners, shoulder pads, canopies, skirts, sleeping bags, socks, sponges, surface protectors, surgical gowns, tampons, shirts,

The product of the invention is also in the form of a powder which is a component of a composition, particularly a powdered composition, which is used in contact with water and which has the property of releasing a non-aqueous liquid from the components of the powdered product upon use. obtain. The compositions described above may consist essentially of a powder matrix containing an included non-aqueous liquid. In this case, the composition comprises approximately 50-100% by weight of powdered product. However, compositions generally consist of a powdered product and other ingredients (e.g., an abrasive such as calcite, a water absorbent such as talc, or a polymer capable of absorbing an amount of water at least equal to its own weight). Consists of a mixture. If mixed powders are used, at least 1% by weight, preferably at least 10% by weight of powder product must be used. Specific examples of compositions containing powder products of the invention are as follows. For example, polishing powders used in the bathroom or kitchen, powdered antiperspirants or deodorants or phase powders applied topically to human skin, powdered fruit drinks, powdered soup mixes. It is to be understood that the above examples are not exhaustive of the products of the invention. The products of the present invention are packaged in a sealed container that does not permit the ingress of moisture to prevent inadvertent contact with moisture and release of the contained non-aqueous liquid prior to use. However, if the storage environment is dry, unpackaged products can retain their contained non-aqueous liquids for months or even years. However, under actual storage conditions in homes, offices, shops, and factories, the non-aqueous liquids contained may be gradually released due to the presence of water vapor in the air due to changing climatic conditions. Gradual release of non-aqueous liquids entrained by water vapor is advantageous, for example when dispensing deodorizers, fragrances or pesticides into enclosed spaces over long periods of time, but Storing the product in moisture-impermeable packaging is necessary to take full advantage of such effects. The packaging material and condition of the package containing the product of the present invention may be any as long as the package forms a moisture-impermeable airtight container. The packaging material may be flexible, such as a flexible plastic material or metal foil or a laminate thereof, or it may be rigid, such as a rigid plastic material, metal or glass. The packaging material may be in liquid form, in which case the material can be sprayed or dip coated onto the product and dried to form a continuous, moisture impermeable film. The package itself can take a variety of forms depending on the manufacturer or the consumer. Examples may include sealed bags or packets that are easy to open during use, or jars or cans with resealable lids that can absorb the product of the invention. The present invention also relates to a method of manufacturing a substantially dry-touch product contained in a moisture-impermeable closed container. The method consists of the following steps: (i) contacting an aqueous liquid with a matrix of polysaccharides or proteins or mixtures thereof; (ii) contacting a matrix that is miscible with said aqueous liquid and has a dielectric constant of 1.5 to 40; (iii) drying the matrix to remove any remaining liquid on the surface to form a dry-touch product; (iv) packaging the product in a moisture-impermeable sealed container. The present invention also relates to a method for manufacturing a substantially dry-touch product, comprising the following steps: (i) polysaccharides or proteins or mixtures thereof, C ₁ −
(ii) contacting the matrix with a first non-aqueous liquid selected from the group consisting of _C4 alkanols, aldehydes, ketones and mixtures of said compounds with water; (iii) drying the matrix to remove any remaining liquid on the surface to form a dry-touch product; The sugar and/or protein matrix is
Ideally, the contact with one moisture-impermeable liquid is followed by successive contact with two or more non-aqueous liquids. However, each non-aqueous liquid is miscible with the previous non-aqueous liquid and has a dielectric constant (at 0-25°C) lower than that of the previous non-aqueous liquid. Regardless of the number of non-aqueous liquids that come into contact with the matrix, the substantially dry surface obtained after drying is
Tight products contain non-aqueous liquids that are included so that they can be liberated when the product is brought into contact with water. Aqueous liquids include water, acids, bases, salts,
Examples include aqueous solutions of _C1 - _C4 alkanols, aldehydes or ketones. Particularly preferred are aqueous solutions containing sulfuric acid, sodium hydroxide or other electrolytes. Examples of non-aqueous liquids or solutions of solvent and solute that can be used in the method of the invention are as described above. It is important in the present invention that the liquids that are in continuous contact with the matrix are miscible with each other. However, it should also be understood that liquids that are normally immiscible with each other can be made miscible with the use of solubilizers. When transferring a matrix from one liquid to a next liquid with a lower dielectric constant than the liquid, there is no need to dry the matrix. However, it is preferred to drain excess liquid from the matrix before contacting it with the next liquid. It is common that the temperature of each liquid with which the matrix is contacted or immersed will affect the rate of transfer of the liquid into the matrix. Generally, the higher the contact temperature, the faster the liquid will migrate into the matrix. The maximum temperature of contact will normally not exceed the normal pressure boiling point of the non-aqueous liquid involved. The contact time of each liquid with the matrix generally affects the amount of liquid transferred to the matrix. Typically, the contact time is between 1 minute and 30 minutes; if the contact time is less than 1 minute, the liquid absorption will not be sufficient, while if the contact time is more than 30 minutes, the amount of liquid absorbed by the polymer fiber matrix will be reduced. Cannot increase significantly. The method of the invention involves continuously transferring a piece of matrix in the shape of the final product from one liquid to the next, preferably with the transfer from one liquid to the next diluting the next liquid. In order to minimize contamination with previous liquids, a simple drainage process may be provided between the liquids. Another method is to supply a matrix in the form of a continuous sheet, strip, filament or web to each liquid in succession, with the liquids being separated by means such as passing through a pair of rollers so that any excess liquid remaining on the surface can run off or Squeezed out. In this "continuous" process, the matrix in the form of a sheet, strip or web, which has exited the final liquid, is dried and then packaged as is, for example as a roll, or cut into pieces of a size suitable for the particular application and then packaged. Hereinafter, the present invention will be discussed in detail based on Examples. Example 1 Viscose rayon fiber (cellulose) as a polysaccharide matrix with n- as a non-aqueous liquid
Figure 2 illustrates an unpackaged product incorporating heptane. A small piece of viscose rayon woven fiber measuring 5 cm x 5 cm was soaked in distilled water for 15 minutes and briefly dehydrated.
It was transferred to an ethanol bath and soaked there for 15 minutes.
Remove small pieces of rayon fiber from ethanol,
After brief draining, the pieces were transferred to the next bath. These bath immersion, draining and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquid used is
It was as follows. Water → ethanol → acetone → iso-propanol → chloroform → trichloroethylene → toluene → n-heptane The viscose rayon fiber pieces were removed from the final bath containing n-heptane, and after deliquing, they were vacuum dried in an oven at 85°C for 4 hours. Ta. The amount of non-aqueous liquid contained in viscose rayon fiber products was determined by gravimetric analysis and proton T ₂ nmr.
Calculated from analysis of decay signals. The results confirmed that the dried viscose rayon product contained approximately 10% by weight of non-aqueous liquid. Although the viscose rayon fiber product was odorless in the dry state, n-heptane was immediately liberated when the product was sprayed with water. This is evident from the odor of n-heptane and the fact that the product can be used to wipe and clean oily surfaces. Products with similar properties were packaged in saran-coated methathene bags and sealed to drive out moisture. However, some products were not packaged. The packaged product retained its ability to liberate n-heptane when moistened with water, even when stored at 20° C. for 6 months. In the case of unpackaged products, even after only a few weeks of storage, n-heptane was gradually lost due to contact with water vapor in the air. Example 2 The amount of n-heptane as a non-aqueous liquid incorporated into thick viscose rayon fibers as a cellulose matrix in 12 dipping sequences was measured. Each 5 cm square piece of viscose rayon fiber is placed first.
It was immersed in each liquid in the order shown in the table. The immersion time for each liquid was 15 minutes, and the final drying time was 5 hours at 85°C in a vacuum oven. The product thus produced can then be packaged in a moisture-impermeable container.

[Table] * Calculated by weight analysis
X Liquid without soaking Up to 12% by weight of solvent (mainly n-heptane)
It is clear from Table 1 that in order to obtain inclusions, it is necessary to immerse the thick viscose rayon product in water and then pass it through five non-aqueous liquids. If acetone and isopropanol are omitted (Example 2F), the amount of n-heptane included is very low, probably because trichlorethylene is immiscible with ethanol. From this it is recognized that it is important that the non-aqueous liquids that are immersed one after the other are miscible. As is clear from Example 2L, it is also possible to start the inclusion step with a short chain alcohol such as ethanol instead of water. Each product of Examples 2A-2L must be packaged in a moisture-impermeable, airtight container. Example 3 Glazed cotton (cellulose matrix)
Example is an unpackaged product containing trichlorethylene as a non-aqueous liquid. A piece of woven polished cotton fiber measuring 5 cm x 5 cm was soaked in distilled water for 15 minutes, briefly dehydrated and then transferred to an ethanol bath and soaked therein for 15 minutes. A small piece of cotton fiber was removed from the ethanol, briefly dehydrated, and then transferred to the next bath. These bath immersion, draining and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquids used was as follows. Water -> Ethanol -> Acetone -> Iso-propanol -> Chloroform -> Trichlorethylene The cotton fiber pieces were taken out from the final bath containing trichlorethylene, and after deliquing, they were vacuum dried in an oven at 85°C for 4 hours. The amount of non-aqueous liquid contained in the Cotton fiber product was calculated from gravimetric analysis and analysis of the proton T ₂ nmr decay signal. From this result, it was confirmed that the dried cotton product contained about 10% by weight of non-aqueous liquid. Cotton fiber products were odorless in the dry state, but when the product was sprayed with water, trichlorethylene was immediately liberated. This is evident from the odor of trichlorethylene and the fact that the product can be used to wipe and clean oily surfaces. Products with similar properties were packaged in saran-coated methathene bags and sealed to drive out moisture. However, some products were not packaged. The packaged product retained its ability to liberate trichlorethylene when moistened with water, even when stored at 20°C for 6 months. In the case of unpackaged products, even after only a few weeks of storage, trichlorethylene was gradually lost through contact with water vapor in the air. Example 4 A product in which ethyl lactate as a non-aqueous liquid is incorporated into viscose rayon fibers (cellulose matrix) is exemplified. The product is applied to adhesive plaster and then individually packaged. A piece of viscose rayon woven fiber was soaked in distilled water for 15 minutes, briefly dehydrated, and then transferred to an ethanol bath and soaked therein for 15 minutes. A small piece of rayon fiber was removed from the ethanol, briefly dehydrated, and then transferred to the next bath. These bath immersion, draining and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquids used was as follows. Water -> Ethanol -> Acetone -> Iso-propanol -> Ethyl lactate The viscose rayon fiber pieces were removed from the final bath containing ethyl lactate, deliquified and vacuum dried in an oven at 85°C for 4 hours. The amount of non-aqueous liquid contained in the viscose rayon fiber product was calculated from gravimetric analysis. From this result, the dry viscose rayon product has 12
~16% by weight of organic liquid (primarily ethyl lactate) was found to be included. Although the viscose rayon fiber product was odorless in the dry state, when the product was sprayed with water, ethyl lactate was immediately liberated. This is evidenced by the odor of ethyl lactate and the decrease in the pH of the skin and the water used after using the moistened textiles. When a viscose rayon product is applied to an adhesive bandage, an occlusive plaster is obtained. This plaster is used for topical treatment of acne and other skin conditions, taking advantage of the gradual release of the ethyl lactate it contains when exposed to moisture from the skin. Products with similar properties were packaged in saran-coated methathene bags and sealed to drive out moisture. However, some products were not packaged. The packaged product retained its ability to liberate ethyl lactate when moistened with water, even when stored at 20°C for 6 months. In the case of unpackaged products, even after only a few weeks of storage, ethyl lactate was gradually lost due to contact with water vapor in the air. Example 5 An unpackaged product is illustrated in which viscose rayon fibers (cellulose matrix) are incorporated with an iso-propanol solution of trichlorophenol (TCP) as the non-aqueous liquid. A small piece of viscose rayon woven fiber measuring 5 cm x 5 cm was soaked in distilled water for 15 minutes and briefly dehydrated.
It was transferred to an ethanol bath and soaked there for 15 minutes.
Remove small pieces of cotton fiber from ethanol,
After brief dehydration, the pieces were transferred to the next bath. These bath immersion, draining and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquids used was as follows. Water → Ethanol → Acetone → TCP (10% by weight)
The viscose rayon fiber pieces were removed from the final bath containing the iso-propanol solution TCP solution, deliquified, and vacuum dried in an oven at 85° C. for 4 hours. The amount of non-aqueous liquid contained in the viscose rayon fiber product was calculated from gravimetric analysis. The results confirmed that the dried viscose rayon product contained approximately 8-9% by weight of non-aqueous liquid (primarily an iso-propanol solution of TCP). The products thus produced were then individually packaged in moisture-impermeable metal foil sachets. Although the viscose rayon fiber product was odorless in the dry state, when the product was sprayed with water, an iso-propanol solution of TCP was immediately liberated. This is evident from the smell of TCP and the fact that the product can be used to disinfect human skin. Example 6 Bactericidal agent 2,4,
Figure 2 illustrates an unwrapped sterile towel product incorporating a solution of 4'-trichloro-2'-hydroxydiphenyl ether (DP300) in iso-propanol. A piece of viscose rayon woven fiber was soaked in distilled water for 15 minutes, briefly dehydrated, and then transferred to an ethanol bath and soaked therein for 15 minutes. A small piece of rayon fiber was removed from the ethanol, briefly dehydrated, and then transferred to the next bath. These bath immersion, draining and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquids used was as follows. Water -> Ethanol -> Acetone -> Iso-propanol -> 0.2% DP300 solution in isopropanol The viscose rayon fiber pieces were removed from the final bath containing the DP300 solution, dehydrated and vacuum dried in an oven at 85°C for 4 hours. The amount of non-aqueous liquid contained in the viscose rayon fiber product was calculated from gravimetric analysis. The results confirmed that the dried viscose rayon product contained an approximately 8% by weight solution of DP300 in iso-propanol. Although the viscose rayon fiber product was odorless in the dry state, the DP300 solution was immediately liberated when the product was sprayed with water. This is evidenced by the odor of iso-propanol and the fact that wiping the slide with the moistened product can completely inhibit microbial growth on the glass. Products with similar properties were packaged in saran-coated methathene bags and sealed to expel water and water vapor. However, some products were not packaged. The packaged product has a shelf life of 20% for 6 months.
DP300 when moistened with water, even when stored at °C.
It retained the property of releasing the solution. In the case of unpackaged products, even after only a few weeks of storage, the DP300 solution was gradually lost due to contact with water vapor in the air. Example 7 Addition of perfume as a non-aqueous liquid to cellulose powder (cellulose matrix) with a particle size of 15 to 40 microns.
- Illustrating an unpackaged product containing a heptane solution. This powder product is to be mixed into hard surface polishing powder or deodorizing powder. Cellulose powder was placed in a glass column and distilled water was added until the cellulose powder was completely wetted. After soaking there for 5 minutes and removing excess water from the column, ethanol was added to the cellulose powder in the column from above. Ethanol was allowed to permeate the cellulose powder for 5 minutes and then briefly dehydrated. These liquid infiltration and liquid removal operations were repeated using different non-aqueous liquids. The immersion order of the liquids used was as follows. Water → Ethanol → Acetone → Iso-propanol → Trichlorethylene → Fragrance (10% by volume) n
-Heptane solution After draining the final solution from the column, the cellulose powder was taken out and vacuum dried in an oven at 85°C for 4 hours. The amount of non-aqueous liquid contained in the cellulose powder matrix thus obtained was calculated by gravimetric analysis. The results confirmed that the dried matrix contained approximately 8% by weight of non-aqueous liquid. The cellulose powder product thus obtained was odorless in the dry state, but when the product was sprayed with water, a solution of perfume in n-heptane was immediately liberated. This is evident from the characteristic odor of the perfume solution. Cellulose powder products may be, for example, (i) calcite-based, with a final fragrance level of 0.1-0.2% for use as a hard surface polishing powder; (ii) talc-based, with a final fragrance level of 0.1-0.2% for use as an anti-odor talc powder or antiperspirant powder. It is blended with to bring it to the level required for use as an agent. The powder composition described above was packaged into dispensing cans and sealed to expel moisture. Example 8 A viscose rayon fiber (cellulose matrix) was incorporated with an iso-propanol solution of Florida orange flavor as the non-aqueous liquid.
An example of an unpackaged product. A small piece of viscose rayon woven fiber measuring 5 cm x 5 cm was soaked in distilled water for 15 minutes and briefly dehydrated.
It was transferred to an ethanol bath and soaked there for 15 minutes.
Remove small pieces of rayon fiber from ethanol,
After brief dehydration, the pieces were transferred to the next bath. These bath immersion, dehydration and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquids used was as follows. Water → Ethanol → Acetone → Orange flavor (5% by weight) in iso-propanol solution The viscose rayon fiber pieces were taken out from the final bath, and after deliquing, they were vacuum dried in an oven at 85°C for 4 hours. The amount of non-aqueous liquid contained in the viscose rayon fiber product was calculated from gravimetric analysis. The results confirmed that the dried viscose rayon product contained approximately 8% by weight of non-aqueous liquid. The product thus produced was packaged in a moisture-impermeable container. The viscose rayon fiber product was odorless in the dry state, but when the product was sprayed with water, an orange-flavored iso-propanol solution was immediately liberated. This is evident from the smell of oranges and the taste of oranges when the dry textile product is put into the mouth. Example 9 Example 8 was repeated substituting spearmint flavor, rose flavor or aniseed flavor for the Florida orange flavor. Similar results were obtained. Example 10 Viscose rayon yarn (Tenasco Super)
(cellulose matrix) with 33 parts of L-menthol and Brazilian peppermint oil as a non-aqueous liquid.
An unpackaged product containing 67 parts of n-heptane solution is illustrated. A length of viscose rayon yarn was soaked in distilled water for 15 minutes, briefly dehydrated, and then transferred to an ethanol bath and soaked therein for 15 minutes. After removing the yarn from the ethanol and briefly draining it, the yarn was transferred to the next bath. These bath immersion, draining and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquids used was as follows. Water → ethanol → acetone → iso-propanol → trichlorethylene → L-menthol: n of Brazilian peppermint oil (33:67) (10% by weight)
-Heptane Solution The viscose rayon yarn was removed from the final bath containing the n-heptane solution, dehydrated and vacuum dried in an oven at 85°C for 4 hours. The amount of non-aqueous liquid contained in the viscose rayon fiber product was calculated from gravimetric analysis. From this result, dry viscose rayon products have approximately
It was confirmed that a 10% by weight solution of L-menthol-Brazilian peppermint oil in n-heptane was included. Although the viscose rayon yarn was odorless in the dry state, spraying the yarn with water immediately liberated a solution of L-menthol-Brazilian peppermint oil in n-heptane. This is evidenced by the peppermint odor and the peppermint and menthol taste when the yarn is placed in the mouth. The viscose rayon yarn thus produced is suitable for use as dental floss and can be packaged in impermeable pouches made of plastic material until ready for use. Example 11 An unpackaged product is illustrated in which woven wool fibers (keratin matrix) incorporate trichlorethylene as a non-aqueous liquid. A piece of wool fiber measuring 5 cm x 5 cm was soaked in distilled water for 15 minutes, briefly dehydrated, and then transferred to an ethanol bath and soaked therein for 15 minutes. After removing the wool fiber pieces from the ethanol and briefly deliquifying them, the pieces were transferred to the next bath. These bath immersion, draining and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquids used was as follows. Water → Ethanol → Acetone → Iso-propanol → Trichlorethylene A piece of viscose rayon fiber was removed from the final bath containing trichlorethylene, and after deliquing, it was heated to 85°C.
It was vacuum dried in an oven for 4 hours. The amount of non-aqueous liquid contained in the wool fiber product was calculated from gravimetric analysis. This result confirmed that the dried wool product contained about 10% by weight of non-aqueous liquid. The wool product was then packaged in a moisture-impermeable container. Although the wool product was odorless in the dry state, trichlorethylene was immediately liberated when the product was sprayed with water. This is evident from the odor of trichlorethylene. Example 12 A product is illustrated in which non-woven cellulose fibers (J-cloth) (cellulose matrix) incorporate trichlorethylene as a non-aqueous liquid. The product is packaged in an airtight screw-topped jar. A piece of non-woven cellulose fiber measuring 5 cm x 5 cm was soaked in distilled water for 15 minutes, briefly dehydrated and then transferred to an ethanol bath and soaked therein for 15 minutes. After removing the fiber pieces from the ethanol and briefly deliquifying them, the pieces were transferred to the next bath. These bath immersion, draining and transfer operations were repeated in a series of baths, each containing a different non-aqueous liquid. The immersion order of the liquids used was as follows. Water -> Ethanol -> Acetone -> Iso-propanol -> Trichlorethylene The non-woven cellulose fiber pieces were removed from the final bath containing trichlorethylene, dehydrated and vacuum dried in an oven at 85°C for 4 hours. The amount of non-aqueous liquid contained in the non-woven cellulose fiber product was calculated from gravimetric analysis. The results confirmed that the dried cellulose product contained about 6% by weight of non-aqueous liquid. The J-Cross product was packaged in a moisture-impermeable jar with a screw top. Although the nonwoven cellulosic fiber product was odorless in the dry state, trichlorethylene was immediately liberated when the product was sprayed with water. This is evident from the odor of trichlorethylene and the fact that the product can be used to wipe and clean oily surfaces. Example 13 Woven cellulose fiber (cellulose matrix)

Example 22 A tea bag is exemplified in which Earl Gray tea flavor is contained in a perforated non-woven cellulose bag to impart flavor to the low-quality black tea leaves enclosed in the bag. A perforated non-woven cellulose tissue suitable for producing teabags in the form of a continuous web,
First, pass it through water, then ethanol, acetone,
A 5% isopropanol solution of Earl Gray Tea flavor having the following composition was passed in this order: % by weight bergamot oil 95 rose oil 3 lemon oil The residence time in each liquid is 15 minutes and the web is passed through the nip of a pair of rollers to squeeze out excess liquid before moving on to the next liquid. There is no need for the web to be completely dry between transfers from one liquid to the next. After passing through the final liquid Earl Greatey flavor solution, the web was dried at 85℃ for 3 hours, then formed into 4cm square pouches, filled with black tea leaves, and finally sealed with black tea leaves. Close the sachet. Packed in a moisture-impermeable foil container as a bundle of 10 sachets. When a sachet (tea bag) is leached into hot water,
A delicious black tea with the aroma of Earl Greatea is obtained. Example 23 A product in which a bread flavor (non-aqueous liquid) is incorporated into a wrapper (cellulose matrix) for wrapping freshly baked bread is exemplified. The procedure of Example 22 was repeated. However, for the perforated non-woven cellulose tissue, we used a 40cm wide web, which is suitable for wrapping a loaf of bread, and for the flavor, we used bread flavored iso-propanol with a concentration of 5% by weight. Use a solution (non-aqueous liquid). Bread flavor has the following composition. Weight % Iso-butanol 1.274 Glacial acetic acid 1.274 Butyric acid 1.274 Iso-Butyric acid 0.644 Pentanoic acid 0.32 Hexanoic acid 0.644 β-Phenyl Ethyl Alcohol 3.8 γ-Nonalactone 0.644 Phenylacetic acid 0.126 Iso-Propanol 90.0 Non-woven cellulose containing the above bulleted flavors Teitshuyu The dried web (product) must be stored in a moisture-impermeable container until use to avoid premature release of the bread flavor due to water vapor in the air. The tissue product thus treated is used to wrap freshly baked bread. Steam is released very slowly from freshly baked bread, and the bread flavor is also released appropriately, so even if stored for a long period of time, the appearance of the bread remains freshly baked. To prevent bread flavors from escaping prematurely from bread wrapped in treated cellulose material,
It is possible to apply a moisture-impermeable polyethylene wrap film to the outside of the bread until it is placed on the shelf or sold. Patting the treated cellulose wrap material with water may release the bread flavor from the material. This can provide the aroma of freshly baked bread even if the bread has been baked many months in advance and stored frozen to avoid microbial spoilage and growth. Example 24 This example illustrates a bag containing herbs and spices used for seasoning stews and soups, in which herb-spice flavor (non-aqueous liquid) is incorporated into a woven cotton material (cellulose matrix). The procedure of Example 23 was repeated. The flavor used was an iso-propanol solution of "bouquet garni" flavor (5%). “bouquet garni”

Once formed into a bag, the bag can be filled with desired herbs or spices and used. The bag should be packaged in a moisture-impermeable container until used. When you add this bag to stew or soup stock,
The "bouquet garni" flavor is released on contact with water and imparts the taste of said flavor to the food product. Example 25 A product in which a linen-cotton rolled towel (cellulose matrix) contains a fragrance (non-aqueous liquid) is exemplified. The product is wrapped in a moisture-impermeable plastic film until used. 30 used for rolled towel dispenser
