[0025] —次性吸收物品具有一个纵向中心线L,该中心线把吸收物品分成两个实际上对称的相对的一半,以及一条横向中心线T。 [0025] - Ci absorbent article having a longitudinal centerline L, the center line of the absorbent article is divided into two substantially symmetrically opposite half, and a transverse centerline T. 在此使用的术语"纵向"是指吸收物品的一个假想线,轴或者方向,该假想的线、轴或方向通常在吸收芯的纵向侧边边界之间的中间,且对准把站立的穿戴者平分成左边身体一半和右边身体一半的垂直面。 As used herein the term "longitudinal" refers to an absorbent article imaginary line, axis, or direction generally intermediate between the longitudinal side margins of the absorbent core line, axis or direction of the imaginary and the alignment of the standing wearer Ping's body into the left half and the right half of the body vertical plane. 术语"横向"是指一条假想线、轴或方向,它通常与纵向方向正交,且通常相对于穿戴者的横向取向。 The term "lateral" refers to an imaginary line, axis or direction generally orthogonal to its longitudinal direction and is generally transverse orientation with respect to the wearer. [0026] 透液性顶层2优选柔顺、感觉柔软和对穿戴者皮肤无剌激作用的材料。 [0026] The liquid-permeable top layer 2 is preferably compliant, soft feeling to the wearer's skin material and no stimulation effect. 此外,顶层是透液的,液体能迅速透过其厚度。 Further, the topsheet is liquid pervious, permitting liquid to readily penetrate through its thickness. 适合的透液性顶层2可以由很多材料制成,如由纺织纤维、无纺纤维,如多孔成形热塑性膜之类的聚合材料,多孔塑料薄膜,和湿法成型热塑性膜;多孔泡沫,网状泡沫;网状热塑性膜;和热塑性稀松布。 Suitable liquid-permeable top layer 2 may be made of many materials, such as textile fibers, nonwoven fibers, polymeric materials such as apertured formed thermoplastic films or the like, apertured plastic films, and wet-molded thermoplastic films; porous foams, reticulated foams; reticulated thermoplastic films; and thermoplastic scrims. 合适的纺织或者无纺纤维可以由天然纤维(例如羊毛或者棉纤维),合成纤维(例如,多聚酯纤维,聚丙烯或者聚乙烯纤维之类的复合纤维)制成;或者由天然纤维和合成纤维组合而成。 Suitable fibers may be woven or nonwoven, synthetic fibers (e.g., multi-polyester fibers, polyethylene fibers or polypropylene, composite fibers) made of natural fibers (e.g., wood or cotton fibers); and synthetic or natural fibers fiber combination. 此外,透液性顶层2也可以是一种多孔成形膜。 In addition, liquid-permeable top layer 2 may be formed is a porous membrane. 该多孔成形膜优选是一种三维多孔成形膜,该膜可渗透体内分泌物,无吸收性,能减少液体回流而再润湿穿戴者皮肤。 The preferred apertured formed film is a three dimensional apertured formed film that is pervious to body exudates, non-absorbent, liquid reflux can be reduced rewet the wearer's skin. 因此,接触身体的成形膜表面保持干爽,从而减少对身体的沾污,给穿戴者带来更舒适的感觉。 Thus, the surface of the formed film in contact with the body remains dry, thereby reducing body soiling of the wearer feel more comfortable. 成形膜顶层接触身体的或暴露的表面可以通过用表面活性剂处理而具有亲水性,这有助于使液体透过顶层,其传递速度比非亲水性的接触身体表面传递速度快,从而减少了分泌物流出顶层而不流入吸收芯、被吸收芯吸收的可能性。 Top layer or film is formed in contact with the exposed surface of the body may be hydrophilic by treatment with a surface active agent, which contributes to the liquid pervious topsheet which is transmitted faster than the transfer body surface was not hydrophilic contact velocity, so that It reduces the possibility of secretions out of the top layer into the absorbent core without being absorbed by the absorbent core.

[0027] 不透液底层4由柔性材料构成,该材料不透液体(如月经和或尿),以防止液体可能从吸收芯3中挤出,也可能意外地溢出吸收芯的分泌物接触和污染穿戴者的内衣。 [0027] The liquid impervious backsheet 4 is made of a flexible material which is impervious to liquids (e.g., menses and or urine) to prevent liquid may be expelled from the absorbent core 3, it may accidentally spill exudates contact the absorbent core contamination of the wearer's underwear. 在使用时,不透液底层夹在吸收芯3和穿戴者衣服之间,这里使用的术语"柔性"是指柔软、柔顺、能够迅速与人体形状和轮廓保持一直的材料。 In use, the liquid impervious backsheet sandwiched between the absorbent core 3 and the wearer's clothing, the term "flexible" as used herein refers to a soft, compliant and will readily been holding the material and shape of the body contours. 因此不透液底层4可以由已被处理成不透液体的纺织或者无纺纤维材料,聚合物薄膜例如聚乙烯或者聚丙稀的热塑性薄膜,或者复合材料如薄膜的涂覆无纺布制成。 Thus liquid impervious backsheet 4 can be treated to have a liquid impervious woven or nonwoven fibrous material, polymeric films such as polyethylene or polypropylene coated with a thermoplastic film, or a composite material such as a thin film made of a nonwoven fabric. 此外,该不透液底层4可以允许蒸气从吸收芯逸出(即透气),同时还防止分泌物通过不透液底层4。 Further, the liquid impervious backsheet 4 can permit vapors to escape from the absorbent core (i.e., breathable) while still preventing exudates by a liquid impervious backsheet 4.

[0028] 吸收芯3用于收集和贮存人体排泄物。 [0028] The absorbent core 3 is used to collect and contain body exudates. 吸收芯通常可以由任何柔软、柔顺、舒适、 对穿戴者皮肤无剌激作用、并且能够吸收和存留体内分泌物的材料制成。 The absorbent core generally be, and capable of absorbing and containing body exudates be made from any material that is soft, compliant, comfortable, no stimulation to the wearer's skin. 吸收芯可以由一次性吸收物品通用的多种液体吸收材料制成。 The absorbent core of the disposable absorbent article may be a plurality of common liquid-absorbent materials. 合适的吸收材料的例子包括粉碎的木浆(通常称为短纤维),起皱的纤维素填絮,改性交联纤维素纤维,毛细管通道纤维(即现有技术中的纤维内具有毛细管通道的纤维),吸湿泡沫,热粘合气流成网材料,吸湿海绵,合成短纤维,聚合纤维,高吸收聚合物,泥炭苔绒,或热合其它等效材料,或上述材料的结合,但是不限于上述材料。 Examples of suitable absorbent materials include comminuted wood pulp (commonly referred to as staple fibers), creped cellulose wadding, modified cross-linked cellulose fibers, capillary channel fibers (i.e., having a capillary channel fibers within the prior art fibers),,,,, binding thermally bonded absorbent foam material, absorbent sponges airlaid synthetic staple fibers, polymeric fibers, superabsorbent polymer, peat moss, or other equivalent material, heat sealing, or the above materials, but is not limited to the above material.

[0029] 图1-图5清楚表示本发明的第一实施方式,图1是本发明的一次性吸收物品在平展状态下的局部剖视图,透液性顶层(即面向穿着者的尿布的部分)定向于观察者。 [0029] Figures 1-5 clearly showing a first embodiment of the present invention, FIG. 1 is a partial cross-sectional view of the disposable absorbent article of the present invention in a flat state, liquid pervious top (i.e., wearer-facing portion of the diaper) directed to the viewer. 吸收物品具有两条中心线:纵向中心线L和横向中心线T。 The absorbent article has two centerlines: a longitudinal centerline L and a transverse centerline T. 在本发明中,所述的一次性吸收物品, 包括透液性顶层,不透液性底层,及被顶层与底层包裹的吸收芯,并具有横向方向和与该横向方向交叉垂直的长度纵向方向,在吸收芯的纵向和横向各有至少一条细长的从透液性顶层朝向不透液底层的细长槽,吸收芯的纵向和横向的细长槽相互交叉。 In the present invention, the disposable absorbent article, comprising a liquid-permeable top layer, a liquid-impervious bottom layer, and the absorbent core are the top and bottom of the package, and having a transverse direction and a transverse direction intersecting the longitudinal direction perpendicular to the length of in the absorbent core of the longitudinal and transverse direction each have at least one elongated from top liquid-permeable liquid impervious backsheet elongated slot, the elongated longitudinal and transverse grooves intersect the absorbent core. [0030] 如图2所示,在一次性吸收物品的吸收芯的纵向中间有一条横向布置的细长槽n, 该细长槽在吸收芯的整个横向方向(即宽度方向)布置;在吸收芯的横向中间有一条纵向布置的细长槽m,该细长槽m在吸收芯的整个纵向方向(即长度方向)布置。 [0030] As shown, the longitudinal center of the absorbent core of the disposable absorbent article 2 has an elongated groove arranged transversely of n, the elongated slots are arranged in the entire transverse direction of the absorbent core (i.e. the width direction); in the absorbent an elongated central core has a transverse groove arranged in a longitudinal m, the elongated slot m (i.e. the longitudinal direction) disposed in the entire longitudinal direction of the absorbent core. 细长槽的宽度d不能太大,可以在l-15mm,优选为2-7mm,更优选为2-5mm。 The width d of the elongated grooves is not too large, it may be at l-15mm, preferably 2-7mm, more preferably 2-5mm. 在细长槽m、n的底部没有吸收芯,这也就是说,细长槽m、n把吸收芯分割成4块相对独立的小吸收芯。 Elongated slot m, n is not the bottom of the absorbent core, that is to say, an elongated groove m, n dividing the absorbent core into four separate relatively small absorbent core. 为了定位吸收芯, 可以把吸收芯粘接在两层无纺布(或卫生纸)之间,如图3、图4所示;或者可以把的吸收芯粘接于一块无纺布(或卫生纸)上,然后沿吸收芯的纵向侧边向上、向中间包裹起来,如图5所示。 For positioning the absorbent core, the absorbent core can be bonded to the two nonwoven layers (or toilet paper) between FIG. 3, FIG. 4; the absorbent core or may be bonded to a nonwoven fabric (or toilet paper) , and then along the longitudinal sides of the absorbent core upwardly, wrapped up to the middle, as shown in FIG. 当然,用无纺布包裹吸收芯是可选择的,这也就是说,也可以不用无纺布(或卫生纸)把吸收芯包裹。 Of course, the absorbent core is wrapped with a nonwoven fabric selectable, which means that the nonwoven fabric can not (or toilet paper) wrapping the absorbent core. 由于细长槽把吸收芯分割为几块相对独立的小棉芯,每个独立小棉芯都不受其它的独立小棉芯施加的对运动的束缚。 Since the absorbent core of the elongated slot is divided into small pieces independent wicks, wicks each independently are not bound by a small movement of the other independent small wick applied. 没有束缚和均匀的降低束缚使每个独立小棉芯能更精确地、更可靠地和更舒服地适应穿戴者的身体。 Without being bound and even reduce the shackles of each individual small wicks more accurately, more reliably and more comfortably conform to the body of the wearer.
