Description

桥式快速吸附垫体 Bridge rapid adsorption pad body

本实用新型涉及一种卫生用品,特别是桥式快速吸附垫体。 The present invention relates to a hygiene articles, especially bridge rapid adsorption pad body.

在我们的在先95219280.2专利申请中公开了一种快速导流高分子吸收复合垫体,该垫体采用在上层的无纺布和下层的纸之间夹铺有高分子吸水树脂层,然后通过压合成型为一体,以解决现有卫生巾、尿垫等吸释性产品的吸水量而易饱和外溢及扩散导流效果差的问题。 Disclosed in our prior patent application 95219280.2 a rapid flow polymer composite absorbent pad material, the pad is employed between the upper and lower nonwoven fabric sheet plated with a super absorbent polymer interposed layer, then pressing and integrally to solve the problems of the prior sanitary napkins, incontinence pads and other absorbent products, absorbent capacity interpretive apparent saturation spillover and poor diffusion of flow. 因为现有的上述产品大都由无纺布及篷松类发泡层构成,一旦受压或因肢体运动等原因挤压垫体,其吸释在下层中的液体又会被重新挤压出来,而夹设高分子吸水层的目的就在于快速吸释上层的液物并产生膨胀性吸收,即高分子吸水树脂层吸释分泌物中液体后不会再溢出。 Because most of the existing product and the nonwoven fabric is made of a foamed layer canopy conifers, once pressed, or the like reasons limb movements pressing cushion, which release absorbent liquid in the lower layer will be re-extruded, the purpose of the polymer water-absorbing layer is interposed is that liquid absorption was rapid release swelling and generating the upper layer absorbent, i.e. water-absorbing polymer resin layer suction secretions will not release the overflow liquid.

但是高分子吸水树脂在吸收上部渗流物时只具备在同一层面内的吸收扩散作用,而向下层传导扩散作用却较差,因此,当分泌物较多时,其易向垫体或卫生巾的宽度方向渗溢,而无法达到沿纵向较均匀扩散和向下部层体渗释的作用。 However, when the absorbent polymer absorbing resin composition comprising an upper flow diffusion absorption only within the same level, but it is poor to lower conductive diffusion effect, and therefore, when more secretions, the width of which is easy to pad or sanitary napkin infiltration overflow direction, and it can not achieve the effect more uniformly diffused in the longitudinal direction and the downward portion of the release layer body infiltration. 因此既直接影响使用效果。 Therefore, both directly affect the results. 又使得垫体的大部份吸释作用未能发挥。 But also makes the most of the suction pad body failed to explain the role play. 使使用费用增加而原材料浪费。 The use of increased costs of raw materials and waste.

本实用新型的目的就在于克服现有技术的上述缺点和不足,而提供一种设置有两层树脂层,并在两树脂层之间夹设有纸纤维渗导扩散层的,既具有很好同层吸释扩散作用,又具有很好的纵向扩散和向下层渗扩搭桥作用的桥式快速吸附垫体。 The object of the present invention to overcome the above disadvantages and drawbacks of the prior art, and to provide a resin layer provided with two layers, with the paper fibers and interposed permeable conductive diffusion layer between two resin layers, both having a good same release diffusion absorption layer, but also has good longitudinal diffusion and to the lower bridge Nitriding bypass effect rapid adsorption pad body.

本实用新型的目的是通过下面的技术方案实现的:本实用新型有一由上层无纺布,中间树脂层及下层纸压制成的垫体,其特征在于:垫体内设置有两层由纸渗导扩散层隔开的树脂层,在下层的高分子吸水树脂层下部为纸层,由无纺布、树脂层、纸渗导扩散层,高分子吸水树脂层及纸层五层压合成整体垫体。 The object of the present invention is achieved by the following technical solution: a non-woven fabric of the present invention has an upper layer, the intermediate layer and the lower resin sheet pressed into the mat body, wherein: a pad body is provided with two layers of paper guide retentate diffusion layers separated resin layers, the lower layer of the lower resin layer is a water-absorbing polymer layer of paper, a nonwoven fabric, a resin layer, a paper guide infiltration diffusion layer, water-absorbing polymer resin layer and a paper layer laminated synthetic five whole pad body .

由上可见:本实用新型的显著效果是: Seen from above: the present invention is remarkable effects:

第一:由于在两层树脂层之间设有纸层,而纸层既具有快速吸释扩展上部渗流物的特点,又具有很好的沿厚度方向的透湿作用,因此,可将经血、尿液等分泌物、排泄物由上层引透至下层的高分子吸水树脂层进行快速吸释,以避免上层树脂层内部吸释饱和后而易向同层宽度方向渗溢的缺点,以达到很好的搭桥渗导作用。 First: Since the resin layer is provided between two layers of paper, the paper layer having both extended-release characteristics of the rapid absorption composition of the upper flow, and has good moisture permeability in the thickness direction of action, therefore, it may be blood, urine and other secretions, excretions from the upper to the lower layer lead-permeable resin layer of absorbent polymer absorbing quick release in order to avoid the disadvantages of the upper inner resin absorbent layer in the width direction of the release with a saturated apparent permeability layer overflow, in order to achieve very good bridge leading role infiltration.

第2:由于纸层的设置而加之纸层自身吸释扩展作用强的特点,使得上层渗溢液经过它得到沿卫生巾垫体纵向扩散的作用,从而进一步增强扩散渗透面积,加强导流吸释效果。 2: since the paper layer and the paper layer together with the self-priming action of extended release characteristics, so that it gets through the upper retentate discharge diffusion effect of the longitudinal direction of the sanitary napkin of the mat body, thereby further enhancing the diffusion of permeation area, reinforcing the suction flow release effect.
