技术领域 technical field
本发明涉及纸尿裤领域技术，尤其是指一种增加芯体强度和导流作用的纸尿裤及其生产工艺。 The invention relates to the technology in the field of diapers, in particular to a diaper with increased core strength and flow guiding effect and a production process thereof.
背景技术 Background technique
纸尿裤是一次性使用后即可抛弃的产品。以无纺布、卫生纸、绒毛浆、高分子吸水树脂、PE膜、橡皮筋等材料制成。有幼儿专用与成人专用两种。 Diapers are disposable products that can be discarded after a single use. It is made of non-woven fabric, toilet paper, fluff pulp, polymer water-absorbing resin, PE film, rubber band and other materials. There are two types for children and adults.
纸尿裤的核心关键技术是“芯体”。从技术层面来说，纸尿裤芯体至今共经历了三次革命：第一次是半世纪以前，一次性纸尿片的诞生；第二次是八十年代高分子吸水材料在纸尿裤上的应用，使产品的吸液性能得到充分保障，市面主流品牌普遍使用的便是第二代芯体。但这类传统芯体在吸收速度、防反渗程度、厚度及芯体的强韧度等方面仍存在一定的技术局限，使宝宝红屁股、反渗侧漏等问题仍未能完善解决。国内外纸尿裤厂家都在加紧研发一种更轻薄、吸液性能更有保障、表面更干爽的纸尿裤，市场上也不断有一些半成熟的产品推出。直到2012年下半年，推出E芯分阶段纸尿裤系列，宣告第三次芯体技术革新进入成熟应用阶段。这种芯体吸收效率更高、韧性更强，全面解决传统第二代芯体的各大问题。 The core key technology of diapers is the "core body". From a technical point of view, the core body of diapers has experienced three revolutions: the first was the birth of disposable diapers half a century ago; the second was the application of polymer water-absorbent materials in diapers in the 1980s. The liquid absorption performance of the product is fully guaranteed, and the second-generation core is generally used by mainstream brands in the market. However, this type of traditional core still has certain technical limitations in terms of absorption speed, anti-reverse osmosis degree, thickness, and strength and toughness of the core, so that problems such as baby's red buttocks, reverse osmosis and side leakage have not yet been fully resolved. Diaper manufacturers at home and abroad are stepping up the research and development of a thinner, more guaranteed liquid-absorbent diaper, and a drier surface, and some semi-mature products are constantly being launched on the market. Until the second half of 2012, the E-core phased diaper series was launched, announcing that the third core technology innovation has entered the stage of mature application. This kind of core body has higher absorption efficiency and stronger toughness, and comprehensively solves the major problems of the traditional second-generation core body.
然而，目前的芯体普遍没有开设固定孔，当下卫生纸、导流层和上卫生纸等在芯体形成吸收体后，吸收体的强度存在不足的问题，并且吸收体的导流作用不好，影响产品的使用性能。 However, the current core generally does not have fixing holes. After the current toilet paper, diversion layer and upper toilet paper form an absorber in the core, the strength of the absorber is insufficient, and the flow diversion of the absorber is not good, which affects Product performance.
