Description
本發明為關於一種具有適當的硬度、伸張以及有效成分的徐放性，並同時在表面上包含沾黏性較少的膠狀組成物之吸收性物品。且，本發明亦關於一種具有適當的硬度、伸張以及有效成分的徐放性，並同時在表面上具有沾黏性較少的膠狀組成物之不織布。 The present invention relates to an absorbent article having a suitable hardness, stretch, and releasability of an active ingredient, and at the same time, a colloidal composition having less stickiness on the surface. Further, the present invention relates to a nonwoven fabric having a suitable hardness, stretch, and repellent property of an active ingredient, and at the same time having a colloidal composition having less tackiness on the surface.
生理用衛生棉、護墊、尿布等吸收性物品，經由長年累積的技術開發，已漸漸地提升吸收性能等基本性能，與以往相比，吸收經血或尿等***物之後，外漏等較少發生，目前更進一步追求高機能化，例如具有貼近肌膚的著用感、優異之柔軟性及緩衝性等。 Absorbent articles such as sanitary napkins, pads, diapers, etc., have gradually improved the basic performances such as absorption performance through years of accumulated technology development. Compared with the past, they absorb less excrement such as menstrual blood or urine, and have less leakage. Occasionally, it is now pursuing further high-performance, such as having a sense of closeness to the skin, excellent softness, and cushioning.
例如引證1中揭示一種吸收性物品，其係在頂部薄片之外表面中的至少一部份包含有效量的乳液塗覆，該乳液塗覆在20℃下為半固體或固體，且能夠部分地移動到著用者的肌膚。另外，引證1得知，前述乳液塗覆中10~95%為(i)在20℃下具有可塑性或流動一致性，並包含選自石油基底之柔軟劑、脂肪酸酯柔軟劑、烷基乙 氧基化柔軟劑、以及此等之混合物中的1種，且實質上不包含水分之柔軟劑，5~90%為(ii)能夠將柔軟劑固定在頂部薄片外表面上之固定化物質，且具有至少35℃，較佳為具有至少40℃之融點，且選自多元羥基脂肪酸酯、多元羥基脂肪酸醯胺、C14-C22脂肪醇、C12-C22脂肪酸、C12-C22脂肪醇乙氧酸鹽、以及此等混合物之前述固定化物質。 For example, reference numeral 1 discloses an absorbent article comprising at least a portion of the outer surface of the top sheet comprising an effective amount of an emulsion coating which is semi-solid or solid at 20 ° C and capable of partially Move to the user's skin. In addition, Citation 1 indicates that 10 to 95% of the aforementioned emulsion coating is (i) plasticity or flow consistency at 20 ° C, and contains a softener selected from a petroleum base, a fatty acid ester softener, an alkyl group B. An oxylated softening agent, and one of these mixtures, and a softening agent which does not substantially contain water, and 5 to 90% of which are (ii) an immobilizing substance capable of fixing a softening agent to the outer surface of the top sheet. And having a melting point of at least 35 ° C, preferably at least 40 ° C, and selected from the group consisting of polyhydroxyalkanoates, polyhydroxy fatty acid decylamines, C 14 -C 22 fatty alcohols, C 12 -C 22 fatty acids, C 12 - C 22 fatty alcohol ethoxylates, and the aforementioned immobilized materials of such mixtures.
且，引證2中記載一種吸收性物品，其係具備液體透過性的表面薄片、液體不透過性或撥水性的內面薄片以及配置在兩薄片間的吸收體之吸收性物品，且前述表面薄片係由不織布製薄片而成，該不織布製薄片具有密度相互相異的高密度部與低密度部，前述高密度部以及前述低密度部分布在前述表面薄片的平面方向，並在前述低密度部中適用比前述高密度部多量的護膚劑。另外，引證2之段落[0069]中揭示一種護膚劑，其係以5：5之質量比包含有效成分的二醯胺衍生物與硬脂醯醇。 Further, the invention provides an absorbent article comprising a liquid-permeable surface sheet, a liquid-impermeable or water-repellent inner sheet, and an absorbent article disposed between the two sheets, and the surface sheet The nonwoven fabric sheet has a high-density portion and a low-density portion having different densities, and the high-density portion and the low-density portion are disposed in a plane direction of the surface sheet, and are in the low-density portion. A larger amount of skin care agent than the aforementioned high density portion is applied. Further, a skin care agent is disclosed in paragraph [0069] of the reference 2, which is a diamine derivative and an stearyl alcohol containing an active ingredient in a mass ratio of 5:5.
引證1之吸收性物品為：具有35℃以上之融點的固定化物質由於在乳液塗覆內於室溫(25℃)下會結晶化，前述乳液塗覆的黏度會增加，具有使前述乳液塗覆不動化之作用。且，引證2之吸收性物品中，由於所添加之硬脂醯醇具有58℃之融點，可推知會與引證1之吸收性物品一樣具有使護膚劑不動化之作用。 The absorbent article of Citation 1 is that the immobilized material having a melting point of 35 ° C or more is crystallized at room temperature (25 ° C) in the emulsion coating, and the viscosity of the emulsion coating described above is increased to have the aforementioned emulsion. The effect of coating immobility. Further, in the absorbent article of Citation 2, since the added stearyl alcohol has a melting point of 58 ° C, it can be inferred that it has the effect of immobilizing the skin care agent like the absorbent article of Citation 1.
若如此般將乳液塗覆或護膚劑高黏度化，有效成分會被鎖在其內部，並必要以上抑制該有效成分的釋 放，故無法得到滿足有效成分徐放性之點的物品。且，高黏度之乳液塗覆或護膚劑在作為適用於吸收性物品的表面薄片之材料(亦即，直接接觸肌膚的材料)時，柔軟性或伸張較不充分，會有著用感較差之虞。 If the emulsion coating or the skin care agent is highly viscous, the active ingredient will be locked inside, and it is necessary to suppress the release of the active ingredient. Therefore, it is impossible to obtain an item that satisfies the point of the active ingredient. Moreover, when a high-viscosity emulsion coating or a skin care agent is used as a material for a surface sheet of an absorbent article (that is, a material that directly contacts the skin), the softness or stretch is insufficient, and the feeling of use is poor. .
另一方面，引證3中揭示一種膠狀組成物，其關於膠體的硬度或伸張等顯示遅延彈性。此組成物是由數平均分子量為13萬以上之高分子量三嵌段型苯乙烯系熱可塑性彈性體、與數平均分子量為10萬以下之低分子量三嵌段型苯乙烯系熱可塑性彈性體、與軟化劑而成的膠體彈性體，高分子量三嵌段型苯乙烯系彈性體藉由吸收保持多量的軟化劑，能確保組成物的柔軟性，同時藉由含有低分子量三嵌段型苯乙烯系彈性體，能賦予遅延彈性，但在如此之組成物中，關於膠體表面之沾黏性或徐放性，還尚未不充分。 On the other hand, reference 3 discloses a gel-like composition which exhibits elastic elongation with respect to hardness or elongation of the colloid. The composition is a high molecular weight triblock type styrene thermoplastic elastomer having a number average molecular weight of 130,000 or more, and a low molecular weight triblock type styrene thermoplastic elastomer having a number average molecular weight of 100,000 or less. A colloidal elastomer with a softening agent, the high molecular weight triblock type styrene elastomer can ensure the softness of the composition by absorbing a large amount of softener, while containing a low molecular weight triblock type styrene It is an elastomer that imparts elastic elongation, but in such a composition, the adhesion or the release property of the surface of the gel is not yet sufficient.

Among these, styrene-ethylene-butylene-styrene block copolymer (SEBS), styrene-ethylene-propylene-styrene is used in view of the hardness or elongation of the colloid applied to the top sheet. Block copolymers (SEPS) and styrene-ethylene/ethylene-propylene-styrene block copolymers (SEEPS) are preferred. When the diblock copolymer is used as the styrene thermoplastic elastomer (A1, A2), the interaction (π-π stacking) of the styrene hard segment may be weak, and the above may not be sufficiently obtained. The hardness or stretch of the colloid. Further, it is considered that the styrene-based thermoplastic elastomer forms a mesh-like shape by a plurality of agglomerating ranges formed by the interaction of the styrene-based hard segments and a n-olefin soft segment connecting the plurality of agglomerating ranges. Mesh structure and performance as an elastomer. Further, it is considered that such a mesh-like mesh structure has a function of appropriately preliminarily releasing an oil agent (that is, hydrocarbon oil (B) and eucalyptus oil (C)).
前述嵌段共聚合物較佳為包含10~50質量%之苯乙烯系嵌段成分與約50~90質量%之正烯系嵌段成分，更較佳包含為15~40質量%之苯乙烯系嵌段成分與60~85質量%之正烯系嵌段成分，特別佳為包含18~35質量%之 苯乙烯系嵌段成分與65~82質量%之正烯系嵌段成分。苯乙烯系嵌段成分的量若低於10質量%，由於形成前述凝集範圍之苯乙烯系嵌段成分的量會變少，前述苯乙烯系熱可塑性彈性體難以形成上述網孔狀的網狀構造。另一方面，苯乙烯系嵌段成分的量若超過50質量%，由於保持前述油劑等之正烯系嵌段成分的量會變少，能夠保持的油劑等的量會變少，且前述苯乙烯系硬段所形成之凝集範圍的量會變多，故適用在頂部薄片後的膠體會有變硬、著用感變差之虞。 The block copolymer preferably contains 10 to 50% by mass of a styrene block component and about 50 to 90% by mass of a normal olefin block component, more preferably 15 to 40% by mass of styrene.

When the amount of the styrene block component is less than 10% by mass, the amount of the styrene block component forming the agglomeration range is small, and it is difficult for the styrene thermoplastic elastomer to form the mesh-like mesh. structure. On the other hand, when the amount of the styrene block component is more than 50% by mass, the amount of the olefinic block component such as the oil agent or the like is kept small, and the amount of the oil agent or the like that can be held is reduced. Since the amount of the agglomerating range formed by the styrene hard segment is increased, the colloid applied to the top sheet is hardened and the feeling of use is deteriorated.
本發明中，苯乙烯系熱可塑性彈性體混合物(A)是由重量平均分子量相異的2種苯乙烯系熱可塑性彈性體(A1,A2)之混合物而成。 In the present invention, the styrene-based thermoplastic elastomer mixture (A) is a mixture of two styrene-based thermoplastic elastomers (A1, A2) having different weight average molecular weights.
前述2種苯乙烯系熱可塑性彈性體(A1,A2)之中，一個苯乙烯系熱可塑性彈性體(A1)(以下有時記作「低分子量之苯乙烯系熱可塑性彈性體(A1)」)的重量平均分子量是在10萬以上未滿18萬之範圍內，較佳為10萬~15萬之範圍內。若此重量平均分子量未滿10萬，則適用在頂部薄片後的膠體硬度以及伸張會降低。且，另一個苯乙烯系熱可塑性彈性體(A2)(以下有時記作「高分子量之苯乙烯系熱可塑性彈性體(A2)」)之重量平均分子量是在18萬以上30萬以下之範圍內，較佳為22萬~28萬之範圍內。若此重量平均分子量超過30萬，則在前述膠體表面變得容易產生沾黏性。 One of the styrene-based thermoplastic elastomers (A1, A2) is a styrene-based thermoplastic elastomer (A1) (hereinafter referred to as "low-molecular-weight styrene-based thermoplastic elastomer (A1)" The weight average molecular weight is in the range of 100,000 or more and less than 180,000, preferably in the range of 100,000 to 150,000. If the weight average molecular weight is less than 100,000, the colloid hardness and the stretch after application to the top sheet are lowered. Further, the weight average molecular weight of the other styrene-based thermoplastic elastomer (A2) (hereinafter referred to as "high molecular weight styrene thermoplastic elastomer (A2)") is in the range of 180,000 to 300,000 or less. Within the range of preferably 220,000 to 280,000. If the weight average molecular weight exceeds 300,000, the surface of the colloid becomes likely to be sticky.
前述苯乙烯系熱可塑性彈性體混合物(A)之 分散度(亦即，重量平均分子量(Mw)與數平均分子量(Mn)的比(Mw/Mn))在1.25~1.60之範圍內，較佳為1.35~1.55之範圍內。若分散度未滿1.25，則膠狀組成物的物性與使用單一苯乙烯系熱可塑性彈性體時沒有特別差異，適用在頂部薄片後的膠體伸張會變得不充分。另一方面，若分散度超過1.60，則因為前述2種苯乙烯系熱可塑性彈性體(A1,A2)之冷卻固化時間的差異，適用在頂部薄片後的膠體會變得不均質，故膠體之伸張或脆度等物性會降低。 The aforementioned styrene-based thermoplastic elastomer mixture (A) The degree of dispersion (i.e., the ratio of the weight average molecular weight (Mw) to the number average molecular weight (Mn) (Mw/Mn)) is in the range of 1.25 to 1.60, preferably in the range of 1.35 to 1.55. When the degree of dispersion is less than 1.25, the physical properties of the gel composition are not particularly different from those in the case of using a single styrene thermoplastic elastomer, and the colloid stretching after application to the top sheet may be insufficient. On the other hand, when the degree of dispersion exceeds 1.60, the colloids applied to the top sheet become inhomogeneous due to the difference in the cooling and solidification time of the two types of styrene-based thermoplastic elastomers (A1, A2), so the colloid is Physical properties such as stretch or brittleness are reduced.

The mass ratio of the thermoplastic elastomer (A1) to the high molecular weight styrene thermoplastic elastomer (A2) is in the range of (A1) / (A2) = 95/5 to 50/50, preferably 90/10. ~60/40, more preferably 80/20~70/30. In the above mass ratio, if the blending ratio of the low molecular weight styrene thermoplastic elastomer (A1) exceeds 95, the colloid hardness and the stretching after application to the top sheet may become insufficient, and if the blending ratio is not sufficient 50, the adhesion is likely to occur on the surface of the aforementioned colloid.
本發明中，前述膠狀組成物進一步包含在37.8℃下動力黏度為5~50mm2/s之烴油(B)。前述烴油(B)只要是由碳與氫而成的化合物即可，並無特別限制，亦可具有直鏈、分支或環狀構造，亦可具有飽和或不飽和鍵。作為前述烴油(B)，有舉例如正烯系烴(包含1個雙鍵的烯)、石蠟系烴(包含雙鍵也包含三鍵的烷)、乙炔系烴(包含1個三鍵的炔)、包含2個以上雙鍵及/或三鍵的烴、以及芳香族烴、脂環式烴等環狀烴等。更具體來說，有舉出氫化聚異丁烯、流動石蠟、鯊烷、鯊烯等，尤其是氫化聚異丁烯在適用於頂部薄片後，其膠體不會產生沾黏性，也不會產生被徐放的油劑所造成的沾黏感，故能夠較佳地使用。 In the present invention, the gel composition further comprises a hydrocarbon oil (B) having a dynamic viscosity of 5 to 50 mm 2 /s at 37.8 °C. The hydrocarbon oil (B) is not particularly limited as long as it is a compound composed of carbon and hydrogen, and may have a linear, branched or cyclic structure or a saturated or unsaturated bond.

An alkyne), a hydrocarbon containing two or more double bonds and/or triple bonds, and a cyclic hydrocarbon such as an aromatic hydrocarbon or an alicyclic hydrocarbon. More specifically, hydrogenated polyisobutylene, flowing paraffin, squalane, squalene, etc., especially hydrogenated polyisobutylene, after being applied to the top sheet, the colloid does not cause stickiness and does not cause to be released. The oily agent is sticky and can be preferably used.
前述烴油(B)在37.8℃下的動力黏度為 5~50mm2/s之範圍內，較佳為10~30mm2/s之範圍內，更較佳為10~20mm2/s之範圍內。若此動力黏度未滿5mm2/s，則烴油(B)在膠狀組成物的製造時容易揮發，適用於頂部薄片後，其膠體的物性會有產生變化之虞。另一方面，若此動力黏度超過50mm2/s，則適用於頂部薄片後的膠體會變硬，也比較容易產生沾黏性。且，烴油(B)之動力黏度能夠藉由遵照JIS K 2283：2000之「5.動力黏度試驗方法」，使用Cannon-Fenske逆流形黏度計，並在37.8℃之試驗溫度下測定所得。 The hydrocarbon oil (B) has a dynamic viscosity at 37.8 ° C in the range of 5 to 50 mm 2 /s, preferably in the range of 10 to 30 mm 2 /s, more preferably in the range of 10 to 20 mm 2 /s. . If the dynamic viscosity is less than 5 mm 2 /s, the hydrocarbon oil (B) is easily volatilized during the production of the gel composition, and the physical properties of the colloid may change after being applied to the top sheet. On the other hand, if the dynamic viscosity exceeds 50 mm 2 /s, the colloid applied to the top sheet becomes hard and is more likely to be sticky. Further, the dynamic viscosity of the hydrocarbon oil (B) can be measured by using a Cannon-Fenske counter-flow viscometer in accordance with JIS K 2283:2000 "5. Dynamic viscosity test method" and measuring at a test temperature of 37.8 °C.
前述烴油(B)之摻混量相對於前述苯乙烯系熱可塑性彈性體混合物(A)100質量份，在500~4800質量份之範圍內，較佳在800~3000質量份之範圍內，更較佳在1000~1500質量份之範圍內。若此摻混量未滿500質量份，則適用於頂部薄片後的膠體會變硬，伸張也會降低。另一方面，若此摻混量超過4800質量份，則前述膠體會變得太軟，很難維持前述膠體的形狀。 The blending amount of the hydrocarbon oil (B) is in the range of 500 to 4800 parts by mass, preferably 800 to 3000 parts by mass, based on 100 parts by mass of the styrene-based thermoplastic elastomer mixture (A). More preferably, it is in the range of 1000 to 1500 parts by mass. If the blending amount is less than 500 parts by mass, the colloid applied to the top sheet will become hard and the stretch will be lowered. On the other hand, if the blending amount exceeds 4,800 parts by mass, the aforementioned colloid may become too soft, and it is difficult to maintain the shape of the aforementioned colloid.

If the dynamic viscosity is less than 50 mm 2 /s, the eucalyptus oil (C) is easily volatilized during the manufacture of the gel composition, and the colloidal properties after the top sheet may be changed. On the other hand, if the dynamic viscosity exceeds 200 mm 2 /s, the amount of the oil agent or the like is reduced, and the sticking property is likely to occur. Moreover, the dynamic viscosity of the eucalyptus oil (C) can also be measured at a test temperature of 25 ° C by following the "5. Dynamic viscosity test method" of JIS K 2283:2000, and then using a Cannon-Fenske counter-flow viscosity meter. Income.

If the blending amount is less than 20 parts by mass, the amount of the oil agent or the like is reduced. On the other hand, if the blending amount exceeds 60 parts by mass, the amount of the oil agent or the like may become excessive, and the surface of the colloid may become greasy.

前述膠狀組成物除了具有適度的硬度與伸張之外，也具有徐放性，故能夠抑制對各種塗工裝置或成形裝置的附著，並同時進行塗布至成形。另外，前述膠狀組成物中所摻混的低分子量苯乙烯系熱可塑性彈性體比高分子量苯乙烯系熱可塑性彈性體還多，故在100℃前後之溫度條件下也能夠呈現適度的流動性，並且對於不織布或紙、布、正烯系樹脂、PET樹脂等各種基材，能夠輕易地進行塗布等所成之層合或一體化成形等。 In addition to the moderate hardness and stretch, the gel composition has a releasability, so that adhesion to various coating devices or molding devices can be suppressed, and coating can be simultaneously applied to the molding. Further, since the low molecular weight styrene thermoplastic elastomer blended in the gel composition is more than the high molecular weight styrene thermoplastic elastomer, moderate fluidity can be exhibited even at a temperature of about 100 ° C. In addition, for various substrates such as non-woven fabric, paper, cloth, n-olefin resin, and PET resin, lamination or integral molding such as coating can be easily performed.
