Description

DISPOSABLE ABSORBENT ARTICLES COMPRISING A BACK SHEET CONTAINING NATURAL FRAGRANCE AND / OR NATURAL EXTRACT}

The present invention relates to a disposable absorbent article comprising a back sheet containing one or more unencapsulated natural fragrances and / or natural extracts.

Disposable absorbent articles refer to products absorbing body fluids excreted by various physiological actions, and examples thereof include diapers, training pants, adult incontinence products, absorbent underwear, feminine hygiene products, and lactation pads. Body fluids absorbed in absorbent articles generally contain an unpleasant odor, and much research has been conducted to develop a method for removing them.

The most representative of these methods is the method of imparting a fragrance or deodorant to the absorbent article. For example, Korean Patent Nos. 1996-15183 and 5,429,628 disclose absorbent articles in which encapsulated fragrances or deodorants are applied to an absorbent core or top sheet of an absorbent article. In addition, US Pat. No. 5,591,146 discloses microcapsules containing fragrances or deodorants in adhesive bonds attached to a wearer's underwear, and when the openings covering the adhesive bonds are removed, the microcapsules burst to release the fragrances or deodorants. Sanitary napkins are disclosed. In addition, WO 98/51248 discloses an absorbent article in which a fragrance member containing encapsulated fragrance is attached to a back sheet.

However, the process of making the absorbent articles described above must further include encapsulating the fragrance or deodorant and imparting the encapsulated fragrance or deodorant to a particular portion of the absorbent article, and encapsulating the fragrance or deodorant in the manufactured absorbent article. There is a problem that is not uniformly distributed. In addition, when fragrance or deodorant or the like is included in the absorbent core or the top sheet, they may come into direct contact with the wearer's skin, which may cause trouble with sensitive skin.

In addition, when the fragrance or deodorant is applied directly in the manufacture of absorbent articles, variations in the amount of coating are inevitably generated during the process, resulting in variation in the intensity of the fragrance in the finished product, and the initial strength of the fragrance is strong, but the fragrance does not last long. There is a problem. In particular, when the herbal extracts are applied as a fragrance may show differences in terms of expected pharmacological efficacy.

Accordingly, the present inventors have made diligent research efforts to solve the problems of existing disposable absorbent articles containing fragrances or deodorants, and when the back sheet is manufactured by mixing one or more unencapsulated natural fragrances and / or natural extracts with a thermoplastic polymer, A certain amount of natural fragrance and / or natural extract can be applied to the back sheet to maintain the strength and efficacy of the scent of the finished product uniformly, and since the above ingredients are uniformly contained throughout the back sheet, the subtle scent can last for a long time. In addition, the disposable absorbent article to which the back sheet is applied not only prevents the added fragrance ingredient from coming into contact with the skin of the wearer, but also prevents skin trouble, as well as inherent pharmacological and aromatherapy effects of natural fragrances and / or natural extracts. By confirming that we can expect The present invention was completed by writing.

Therefore, an object of the present invention is to prepare by containing one or more unencapsulated natural fragrances and / or natural extracts in the back sheet itself to uniformly apply the ingredients in a constant amount to the back sheet to continuously impart a subtle scent, It is to provide a disposable absorbent article that can be expected excellent deodorizing and deodorizing effect.

To achieve the above object, the present invention provides a disposable absorbent article comprising a back sheet containing one or more natural fragrances and / or natural extracts that are not encapsulated.

Specifically, the present invention relates to a disposable absorbent article consisting of a liquid permeable top sheet, an absorbent core and a liquid impermeable back sheet, wherein the liquid impermeable back sheet contains at least one natural fragrance and / or natural extract that is not encapsulated. It relates to a disposable absorbent product, characterized in that.

The back sheet according to the invention comprising at least one natural fragrance and / or natural extract as described above may be in the form of a film, a nonwoven and a film / nonwoven laminate.

The back sheet in the form of a film according to the invention is a masterbatch (hereinafter referred to as "fragrance-containing masterbatch") prepared by blending one or more natural fragrances and / or natural extracts with a thermoplastic polymer forming a backsheet matrix. After mixing with a common baffle masterbatch, it can be produced using cast or expanded film extrusion, or other suitable film-forming technique. In a preferred embodiment of the present invention, it is suitable to maintain the fragrance persistence in casting the fragrance-containing masterbatch and baffle masterbatch mixture at 170 to 240 ° C., preferably at 180 to 230 ° C., via a T-die extruder. Do.

As described above, the manufacturing process of the back sheet in the form of a film according to the present invention through the T-die will be described in detail. Firstly, the fragrance-containing masterbatch and the baffle masterbatch are mixed at a desired ratio, and these are introduced into an extruder to melt and mix A screen pack device inside the T-die extruder induces fine dispersion and removes debris. The masterbatch mixture is then extruded through a die of a T-die extruder and cast into a film. The cast film is passed through a cooling roll, in which the temperature of the roll is lowered from 10 to 30 lower than a typical roll temperature, such as 20 to 35 ° C., preferably 25 to 30 ° C., in order to maintain the fragrance persistence. It is suitable to maintain the temperature at 15 ° C, preferably 15-25 ° C. The back sheet in the form of a film according to the invention can then be produced by cutting and winding the film according to the desired width. Moreover, the corona treatment or the embossing process which is a general back sheet process can be given to such a manufacturing process as needed.

The fragrance-containing masterbatch used in the present invention has a composition of 30-50% thermoplastic polymer, 0.00001-20% of one or more natural fragrances and / or natural extracts and 40-60% additives, and the baffle masterbatch 40-40 % And additives 60-40%. The additive in the fragrance-containing masterbatch and the baffle masterbatch may be various additives depending on desired properties such as antioxidants, filler particles and dyes.

Each thermoplastic polymer of the fragrance-containing masterbatch and the baffle masterbatch may be the same or different, such thermoplastic polymers being very low density polyethylene (VLDPE), low density polyethylene (LDPE), high density polyethylene. (high density polyethylene, HDPE), polypropylene, copolymers of ethylene and C ₃ -C ₁₂ alpha-olefins, copolymers of propylene and ethylene and / or C ₄ -C ₁₂ alpha-olefins, and atactic in the polypropylene backbone ( Soluble polyolefins, elastomers such as polyurethanes, copolyether esters, polyamide polyether block copolymers, ethylene vinyl acetate copolymers, including propylene-based polymers containing both atactic and isoatactic propylene units , Copoly (styrene / ethylene-butylene), styrene-poly (ethylene-propylene) -s Block copolymers having the formula ABA 'or AB such as styrene, styrene-poly (ethylene-butylene) -styrene, polystyrene / poly (ethylene-butylene) / polystyrene, poly (styrene / ethylene-butylene / styrene), and the like This includes, but is not limited to.

When the two types of masterbatch are mixed, the baffle masterbatch and the fragrance-containing masterbatch may be mixed in various ratios in a desired ratio, but in view of maintaining the persistence of the fragrance and the desired strength of the fragrance, it is generally 99: 1 to 40:60. It is preferable to mix by weight, preferably 96: 4 to 80:20 weight%. Therefore, the amount of natural fragrance and / or natural extract applied is suitably 0.01 to 12% by weight, preferably 0.05 to 5% by weight, relative to the total weight of the back sheet. If the natural fragrance and / or natural extract is added in less than 0.01% by weight, the release of the fragrance is very weak and the function of alleviating the unpleasant odor due to the secretion of the wearer or long-term wearing of the present invention is reduced. On the other hand, when the natural fragrance and / or natural extract exceeds 12% by weight, the release of too strong aroma may not only impair the function of giving the wearer and the user a refreshing mood, but may also cause discomfort.

As described above, the back sheet according to the present invention contains uniformly one or more natural fragrances and / or natural extracts, so that the strength of the fragrance is kept constant and the coarse fragrance is continuously released to the wearer's discharge or prolonged wearing. It is excellent in odor absorbing and odor masking effects of unpleasant odors caused by odors, and also has the advantage of pharmacological and aromatherapy effects unique to natural fragrances and / or natural extracts. . In particular, natural extracts such as herbal extracts can deodorize and deodorize secretions by the inherent scent of natural raw materials, and can be expected to have pharmacological effects such as antibacterial, anti-inflammatory, menstrual irregularities and menstrual pain relief. There is an advantage.

The film thus prepared may be used as a back sheet of the disposable absorbent article according to the present invention, but the film prepared by casting the baffle masterbatch added with filler particles such as CaCO ₃ together with the fragrance containing masterbatch is preheated, It can be used as a back sheet by making it into a film provided with breathability by elongating uniaxially or biaxially through three steps of the stretching process and the heat fixing process. At this time, the stretching process is performed twice, and the stretching temperature is set in consideration of evaporation and decomposition of the fragrance, 20 to 70 ℃, preferably 40 to 45 ℃, elongation rate is 160 to 250%, preferably Preferably 180 to 220%. The heat fixation process is suitably carried out at 20 to 100 ° C., preferably 70 ° C. or lower, in consideration of evaporation and decomposition of the fragrance.

Such stretched film should have a thickness that enables structural integrity and liquid impermeability, for example, it is suitable for the film after stretching to have a thickness of 50 to 300 microns, preferably 100 microns.

In addition, the back sheet according to the present invention is a spunbonded, melt blown, thermal-bonded carded web prepared by a conventional method using the baffle masterbatch and perfume-containing masterbatch described above. (thermal-bonded carded web), thru-air bonded carded web, spunlace, spunbonded-meltblown-spunbonded (SMS) or spunbonded- Nonwoven fabrics of meltblown-meltblown-spunbonded (SMMS), preferably spunbonded-meltblown-spunbonded or spunbonded-meltblown-meltblown-spunbonded Can be.

In addition, the back sheet according to the present invention is laminated with the general nonwoven fabric by using the adhesive or heat adhesive such as solvent type glue (hot melt adhesive) or cold glue (cold glue) Or a laminate of the perfume-containing nonwoven fabric with a general film, or a laminate of the perfume-containing film and the perfume-containing nonwoven fabric. At this time, the applied amount of the perfume applied is about 0.01 to 12% by weight relative to the weight of the film / nonwoven laminate.
