技术领域 FIELD

[0001] 本发明涉及国际专利分类A61F13/15卫生学吸收垫或D06M纤维制品技术,属于非织造布、一次性卫生用品,尤其是珍珠型立体导流套孔双层非织造卫生面料。 [0001] The present invention relates to International Patent Classification A61F13 / 15 hygienic absorbent pad, or fibrous article D06M technology, a non-woven cloth, disposable hygiene products, in particular pearl-type flow sleeve holes perspective bilayer nonwoven fabric health.

背景技术 Background technique

[0002] 现有技术中,卫生学吸收垫或纤维制品种类和应用日益广泛,其中代表性产品包括纸尿裤和卫生巾等,目前中国纸尿裤的常用面层材料,热轧非织造布,热风非织造布、纺粘非织造布、全棉材料。 [0002] In the prior art, hygiene pads or absorbent fibrous product types and used widely, where representative products include diapers and sanitary napkins, the most commonly used surface materials of diapers China, hot-rolled nonwoven fabric, air-through nonwoven cloth, spunbond nonwoven fabrics, cotton material. 目前纸尿裤主要应用平面面料,部分进口纸尿裤采用小馒头立体结构或者竖条状立体结构。 Currently the main application flat fabric diapers, diapers with a small portion of bread inlet dimensional structure or three-dimensional structure of vertical stripe. 这些产品采用两层面层复合,在线压制形成。 These products use two-level layer composite, pressed to form online. 构造可分为面层、吸收芯、底层和各层材料之间用热熔胶相粘结。 Configuration can be divided into the surface layer, with a hot melt adhesive between the absorbent core, and underlayer layers of material. 内层的主要是棉、不织布、纸浆或以上材质复合物所形成的高分子聚合物和高分子聚合物复合纸。 The inner layer mainly cotton, non-woven, polymer and polymer pulp or a composite material over the formed polymer composite paper.

[0003] 在相关产品使用中,尿布瘆产生的最主要原因只由于皮肤长时间的与高水分含量的湿气接触,纸尿裤越干爽与皮肤接触的湿气就越少,引发尿布瘆的机会就越少。 [0003] In the related products, the most important reason only by prolonged contact of the skin with moisture high water content, the less moisture in contact with the skin of the diaper dry diaper Shen generated, causing the chances of the diaper Shen the less.

[0004] 根据研宄分析,纸尿裤的三大要求:不漏、干爽、舒适,2000年婴儿纸尿裤市场产品渗透率平均为2%,到2010年婴儿纸尿裤市场渗透率为32.3%,同期,2010年比2009年婴儿纸尿裤销售额的增长率为31.7% ;纸尿裤漏液的四种现象包括:侧漏、后漏、前漏、底膜漏,目前解决以上问题的主要采用新型的热熔胶喷胶方式。 [0004] According to study based on the analysis, diapers three requirements: no leakage, dry and comfortable, 2000. baby diaper market penetration of products an average of 2%, to 2010, baby diaper market penetration rate of 32.3% over the same period in 2010 baby diapers than the growth rate in 2009 was 31.7% of sales; four diapers leak phenomenon include: side leakage after leak, before the leak, the end of the film leakage current to solve the above problems mainly using the new hot melt glue the way.

[0005] 近几年来,研宄检测数千片在家庭和托儿所幼儿园使用过的纸尿裤,总结出以下结论:在设定不取决于实验室的理论吸收能力前提下,渗漏百分率最高的纸尿裤被认为吸收能力最低,大多数高档婴儿纸尿裤已经能够达到I %或更低的渗漏率,但是当两个纸尿裤的渗漏率相似时,手感较干爽的纸尿裤则被认为吸收能力更高,而影响干爽度的因素又涉及面层材料、导流层和尿裤芯体。 [0005] In recent years, study based on the detection of thousands of pieces of used diapers kindergartens and nurseries in the family, summed up the following conclusion: the premise of set theory does not depend on the absorption capacity of the laboratory, the highest percentage of leaking diapers are considered the lowest absorption capacity, the majority of high-end baby diapers have been able to achieve I% or less of the leak rate, but when the leakage rate is similar to two diapers, feel more dry diapers are considered higher absorptive capacity, and the impact yet another factor involves dry layer of material, and the acquisition distribution layer core diaper.

[0006] 在不断引入的改进技术措施中包含各种创新的概念,比如: [0006] The concept includes a variety of innovative improvements in technology constantly measures introduced, such as:

[0007] 丝滑面料像丝绸似的滑爽,手感很好,但表面张力较小,液体不容易停留,容易造成尿液,特别是便便的泄漏,不宜用在纸尿裤上。 [0007] silky smooth fabrics like silk-like, feel good, but the smaller the surface tension of the liquid is not likely to stay, likely to cause urine leakage especially poo, recommended for use on diapers. 松软面料蓬松,柔软,有一定厚度感,表面张力较大,液体不易在表面滑动,附着力较强,适合用在纸尿裤上。 Fabric soft fluffy and soft, it has a certain sense of thickness, the larger the surface tension of the liquid not slide easily on the surface, strong adhesion, suitable for use in diapers. 有些高端纸尿裤产品在蓬松度的面料上还压上凹凸感更明显的花纹或在无纺布上打孔,加强表面材料的吸附力。 Some high-end products in the diaper fabric bulkiness further pressure on the concavity more pronounced pattern on the nonwoven fabric or perforated, surface adsorption force reinforcing material. 同时,所谓导流即引导液体纵向扩散,所谓防反渗即迅速吸收液体,使液体容易下渗至芯体,受挤压后不易反渗至面层。 At the same time, i.e., the so-called flow guide liquid longitudinal diffusion, i.e., a so-called anti-anti-seepage rapid absorption liquid, the liquid is easy to infiltrate the core, is not easy to rewet the surface layer was squeezed. 所谓临时储液即在同一位置上有多次连续的液体下渗时要有很好的接受及分配液体的性能。 That is a so-called temporary reservoir performance when many successive infiltration have a good liquid acceptance and liquid distribution in the same position. 所谓单层导流层即用一种或几种纤维混合后做成只有一个层面的导流层,功能较单一。 I.e., a so-called single intake layer or mixed with the latter is made of several fiber layers is only one level of the flow, than a single function. 所谓双层导流层即采用两台梳理机,使用几种不同性能的纤维,组合成二层多种功能集一身的导流层。 I.e., so-called double-layer flow using two carding machines, using several different properties of the fibers, a combination of multiple functions into two layers of a layer flow.
