Description

一次性尿布 技术领域 本发明涉及一种一次性尿布， 属吸湿物品领域。 背景技术  TECHNICAL FIELD The present invention relates to a disposable diaper, which is in the field of absorbent articles. Background technique
• 一种至少由透液性表层、不透液性底层以及包裹在所述透液性表 层与不透液性底层之间的吸收芯组成的尿布已为公知， 其具有前腰 区、后腰区及位于前后腰区之间的裆区。尿布由于长时间穿着 ^人体 上，人体自身毛细孔排出的水份以及尿湿后产生的水汽得不到及时的 扩散， 从而使穿用者与尿布接触的皮肤过度水化产生不适， 严重的导 至尿布疹等不利情况的发生。 为改善尿布的透气性能， 2006年 9月 6 日公告的中国专利 CN1829493 即公开一种一次性尿布， 其主要改进 部分是在尿布后腰区的两侧部分别设置一个向宽度方向延伸的第二 翼部， 该第二翼部由.可弹性伸缩的伸缩性复合片形成， 复合片由透气 伸缩性塑料薄膜和透气热熔接性纤维无纺布制成，所述透气伸缩性塑 料薄膜具有皮肤接触侧的第一开口和皮肤不接触侧的第二开口，以形 成向厚度方向延伸的多个透气管， 所述透气热熔接性纤维无纺布， 经 由热熔胶被部分地接合到前述塑料薄膜的两面，以形成向厚度方向起 伏的多个褶裥， 并籍此改进尿布的透气性能。'上述技术方案只是对尿 布的左右腿侧边进行改进，对于湿气最严重的尿布前腰区至档区这一 部分并没有根本上解决其透气性问题， 另外， 其所采用的由透气伸缩 性塑料薄膜和透气热熔接性纤维无纺布制成复合片在非理想拉伸状 态下， 其透气通道呈关闭状态， 因此在实际使用中难以达到改进透气 性之目的。 发明内容 本发明的目的是提供一种透气性好的一次性尿布。  • A diaper consisting at least of a liquid permeable topsheet, a liquid impervious backsheet, and an absorbent core wrapped between the liquid permeable topsheet and the liquid impermeable backsheet, having a front waist region and a back waist The area and the crotch area between the front and rear waist areas. Because the diaper is worn on the human body for a long time, the water discharged from the pores of the human body and the water vapor generated after the urine is not diffused in time, so that the wearer's skin in contact with the diaper is excessively hydrated, resulting in discomfort. Unfavorable conditions such as diaper rash. In order to improve the breathability of the diaper, Chinese Patent No. CN1829493, published on September 6, 2006, discloses a disposable diaper, the main improvement of which is to provide a second extending in the width direction on both sides of the back waist region of the diaper. a wing portion, the second wing portion is formed of an elastically stretchable stretchable composite sheet, and the composite sheet is made of a breathable stretchable plastic film and a gas permeable heat-fusible fiber nonwoven fabric having skin contact a first opening on the side and a second opening on the side of the skin not contacting to form a plurality of vent pipes extending in a thickness direction, the permeable heat-fusible fiber nonwoven fabric being partially joined to the plastic film via a hot melt adhesive Both sides are formed to form a plurality of pleats that undulate in the thickness direction, thereby improving the air permeability of the diaper. 'The above technical solution only improves the left and right leg sides of the diaper, and the part of the front waist region to the gear area of the diaper which has the most moisture is not fundamentally solved the problem of gas permeability, and the venting stretchability adopted by the diaper is not fundamentally solved. The composite film made of the plastic film and the ventilated heat-fusible fiber non-woven fabric has a venting passage in a non-ideal stretch state, so that it is difficult to achieve the purpose of improving the gas permeability in practical use.
