Abstract

本发明提供一种具有改进的弹力侧翼的一次性 使用的训练裤，该弹力侧翼赋与改善的合身与舒适。 一次性使用的尿布具有一吸收芯套及一对与吸收芯 套纵向各边连接的弹力侧翼，在该处，每个侧翼由两 个弹力层粘布片，通过沿着每个布片的无弹力外侧边 缘上的边缝连接而成。

Description

本发明涉及一种一次性使用的吸湿物品，具体地说，用作一次性使用的吸湿尿布及提供大小便失禁者使用的产品。更具体的说，用作一次性使用的训练裤及套穿尿布。本发明直接用于这类商品或产品，特别是训练裤，该训练裤具有一弹力侧翼，该侧翼使训练裤更合身舒适。此处所指“训练裤”也包括具有吸湿芯的套穿尿布。
训练裤已很流行，特别适用于进行上厕所训练的孩子。在过去，已生产一些具有弹力并可延伸的训练裤，以弹性件配置在训练裤上，以致于在裤腰处及裤腿处至少部分地被弹性带围绕。这种用弹性带的方法已表示在以下美国专利，其申请号及申请人为：4，205，679    Repke等;4，610，680        Lafeur;4，610，681    Strohbeen等;4，641，381    heran等;4，909，804    Douglas    Sr;及4，960，414        Meyer。
弹力型一次性使用的训练裤的其他方法也可见于美国专利，专利号为4，490，464;4，938，753及4，938，757专利申请人均为Van    Gompel，等。这些专利公开一种像裤的衣服，上述衣服的形成方法为：将分离的可延伸的布片附着在衣服大身的各侧边。上述分离的可延伸的布片的制作是：先将一种弹力或可延伸的纤维层延伸至所要求的长度，在此状态下将一不能延伸的纤维层如，非织造织物，置于上述已延伸的纤维层上，粘结在一起，然后使各纤维层处于松弛状态。因此，不能延伸的纤维层被聚集在一起。
还有其它制造可延伸布片的方法在以下专利中叙述：美国专利号4，107，364批准日期15，8，1978，专利人Sisson;美国专利号4，209，563批准日期24，6，1980，专利人Sisson;美国专利号4，525，407批准日期25，6，1985专利人Ness;美国专利号4，834，741批准日期30，5，1989专利人Sabee;欧洲专利号409，315，专利权人The    Procter    &    Gamble    company，申请书出版日期23，1，1991。兹以参考方式引入上述专利资料。
尚有其他制造可延伸布片的方法在以下专利中叙述：美国专利申请号07/662536，07/662537及07/662543。申请日期1991年2月28日，受让人The    Proct    &    Gamble    company。这些参考资料介绍制造弹力多层粘布的方法，该方面以机械力延伸无应变伸长的布网，沿伸长方向使弹性至少传递到其起始伸长点。可伸长，无弹力的一层非织造纤维，首先与可防液体渗透的一层弹力纤维在松驰状态时粘合在一起以形成布网，然后将该布网喂入一对相对的压力敷贴器，最好是一个敷贴器具有三度空间的各表面，上述各表面互补地相互间形成不同的角度，布网受到递增的机械延伸（按要求，或不均匀或连续地机械延伸），因此，可延伸的非织造纤维层在延伸方向永久处于延伸状态。当停止机械延伸操作，则弹性层能使布网恢复伸长前的形状及尺寸，因此使得无弹性纤维层在起始伸长方向也可弹性地伸长。
可用上述弹力型无应变延伸的层粘布（即布网）制作训练裤的具有弹性、可延伸的侧翼，但它们并不能完全符合要求。层粘布的可伸长，无弹力的非织造纤维层沿布网的加工方向及与伸长方向垂直的方向，至少是部分会被撕裂。至少部分撕裂的非织造织物会减少非织造织物增强层粘布抗拉强度的作用。此外，弹力纤维层本身一般具有低的抗拉强度及低的抗撕裂扩展的能力。当用弹性层粘布制作训练裤的侧向延伸翼片以便在穿着时在训练裤的侧向（从前到后）可以获得伸长，那么，上述特性将会引起麻烦。因为层粘布的非织造织物的至少部分被撕破的那些线正好位于纵向（机械加工方向）。再者，因为最有利是在训练裤的纵向（加工方向）加工边缝（目的是获得最优制造速度及效率），边缝可能过早的沿边缝被部分地撕破，（例如，当孩子们在活动时），沿非织造织物的至少部分撕破处的一条或多条线，构成加工边缝本身的地方，会进一步损坏，或者是层粘布的非织造织物，或者是层粘布的纤维层，或者两者均损坏。
虽然可以不同的方式解决这些问题，但尚无完全令人满意的办法。例如，在侧翼的前后边沿处或之间增添附加材料以加强接缝处并减少弹力纤维层的损坏。但是发明者已发现修改用以制作弹力侧翼的弹力层粘布的制造方法是可以解决问题的。在制造弹力层粘布的过程中，层粘布喂入位于相对的压力敷贴器时，层粘布的不连续并隔开的各区域未受到或减小了机械的伸长。层粘布经过机械伸长后，在该层粘布在未受到或减小了机械伸长的区域（下文称为“无伸长区”）的中间沿其宽度（在喂入方向）切断。然后将层粘布宽度按适当的长度切断供前、后弹力布片用。无伸长区用作前、后弹力布片各自的外侧边沿部分，然后将上述的外侧边沿部分连接以形成边缝。因此，本发明提供一种显著地改善了强度和抗撕裂特性的边缝，并提供一种具有其边缝牢固性得到改进的弹力侧翼的训练裤。

图3为图2装置中上波纹辊60与下波纹辊61处于配合状态的示意图。
图4图示说明纤维网是如何被切成带有角度的两件弹力布片。
图5图示说明封口处是如何以一定角度附着于弹力布片上。
图6图示说明弹力布片如何附着在底层布与裤脚口之间。
本发明的实施包含训练裤1（图1）的制造，其步骤为：制造弹力布片，该弹力布片具有无机械伸长的外侧边沿部分，制造吸收套，使弹力布片附着在吸收套的边缘上，和在弹力布片的各无弹性外侧边缘部分之间形成边缝，以进一步形成有弹力侧翼的训练裤。
弹力布片一般按以下程序制成：用多层纤维网层压成布网，其中至少有一可伸长，无弹性的非织造纤维层，还有一在松弛状态下的弹性纤维网层;机械延伸沿布网宽度的各部分，沿伸长方向将弹性传递给布网，至少达到其起始伸长点，由此留下无弹性伸长的布网的那些其余部分，并沿所形成的弹性布网的宽度及长度切下作为上述侧翼片的各个前腰及后腰弹力布片。
吸收套的一般制造方法为：在不可渗透液体的底层布及可渗透液体的上罩布之间放一吸收芯。本发明的吸收套一般为矩形，具有侧边，底边及前后腰区。
然后将弹力布片附着在吸收套前后腰的边沿上以使弹力布片的无机械伸长区域成为它的外侧边沿部分。
最后，带有附着有布片的吸收套，在接近纵向中心处对折使前腰区的贴身面（上罩布面）与后腰区的贴身面靠近。附着于前后腰上相对的弹力布片的无机械伸长的边缘的贴身面以热封口连接，从而完成了训练裤。
弹力片10的一般制作方法为：在松弛状态下，将至少一可延伸的无弹性非织造纤维层12及至少一弹性纤维层13层压形成多层布网11;机械延伸沿多层布网11宽度方向的各部分，以便沿延伸方向将弹性传递给布网，并至少达到其起始延伸点，从而留下无弹性布网的那些其余部分;并沿长度及宽度切断此形成的位伸的布网14，用以制作侧翼5的前腰区及后腰区的弹力布片10。
可延伸，无弹性非织造纤维层12的典型实例为包含一疏水型非织造粗梳的纤维网，该纤维网的单位重量范围为：每平方米30-37克，并包含纤度接近1-5丹尼尔的纤维，上述纤维可从美国Hercules    Inc.公司购得。
弹性纤维层13可具有渗水性或无渗水性。例如，纺粘型聚合的非织造织物或塑料薄膜。一种弹性纤维层13的典型实例包括一种聚氨酯，其无负荷厚度约为0.045毫米（2密耳）。实例包括一种日本Synthetic    Rubber    K.K制造的Ds-320C。
无弹性非织造纤维层及弹性纤维层相互粘合形成布网11。粘结各纤维层的粘结剂可以按以下各方式使用：均匀连续的粘结剂层，具有图案的粘结剂层或具有分离的线、螺绒、或斑点等排列的粘结剂。在一种最佳实施方案中，所选用的粘结剂可以延伸，粘合剂敷设器包括一种熔喷敷用系统，如;美国J&M    Laboartor    ies    of    Gainesv    ille    Georgia可提供的Model    No.GM-50-2-1-GH装置。该装置使用一种喷嘴，在机器的横向测量，该喷嘴每厘米有8个孔（每英寸20个孔），每个孔的直径为0.5毫米（0.020英寸）。一种优选的粘结剂为HM-6515热熔粘结剂，可在美国H.B.Fuller    Compony    of    St.    Paul.    Minnesota购得，该粘结剂加热至170℃，以每平方厘米面积使用约0.75-1.25毫克。加热的压缩空气的温度约为220℃，压力约为2500毫米汞柱，从喷嘴的第二级孔中喷出，用以在操作过程中帮助粘结剂的微丝均匀分布。
如图2所示多层布网11通过机械地延伸，沿纤维网宽度形成弹性层粘布区15及无伸长、无弹性的层粘布区20。典型的情况是宽度W约一米的纤维网一次喂入伸长装置。机械地延伸无应变延伸的布网11的装置包括上波纹辊60及下波纹辊61，该二辊相互配合以达到各自的齿及槽相互啮合（图3中更清楚的显示）。布网的区域15在上下波纹辊之间通过，在上波纹辊60的槽62与下波纹61的槽63之间的区域里机械地延伸。布网的区域20通过并排的上波纹辊60的中间未经受任何机械延伸。
最好是使用一种夹持纤维网的装置，该装置夹持正好处于各自机械延伸区外侧的纤维网，以便布网在相互啮合的辊子之间通过时，避免纤维网在平行于延伸方向的收缩，图2显示一种阻止上述收缩的理想装置，一可压缩盘65，该盘直径稍大于上波纹辊的直径，装于上波纹辊上与沟槽部分邻近的各端面处。该可压缩盘紧紧抓住布网并将它牢固地保持在相对应的下波纹辊61无沟槽部分64。
在本发明中机械延伸区15及无延伸区20可沿纤维网的宽度交替变换。被机械延伸的区域15的宽度（如图示X）是根据训练裤要求腰的开口尺寸及延伸的层粘布的弹性程度而定，除此以外还决定于已加工的布网14在延伸后如何切成侧弹力布片10。例如已加工的布网14沿其宽度在每个未经机械延伸部分20的接近中心处切断，如，以刀切断。然后如图4所示，每个已加工的层粘布的宽度能进一步在机械延伸部分的中心处切成两半，同时沿布网长度方向再切出单件长度L，以形成几套第一边10a及第二边10b的弹力布片，供附着于吸收套以形成边缝。按照所生产的训练裤的规格，宽度X的范围为60-140毫米。例如，一大号训练裤打算供体重范围为9-14公斤的孩子用，宽度X约为70-100毫米。更优选范围为74-80毫米，在一个最佳实施方案中，其宽度X约为78毫米。从而，布网在其区域X的中心处已经按其单个长度切断后，本实施方案的单个侧弹性布片的弹性层粘布部分16的宽约为30-70毫米，前面提到的大号训练裤，其宽度X约为35-70毫米，前面提到的大号训练裤，其宽度X为35-50毫米。更佳是37-40毫米，具体的说约为39毫米。
布网的无机械延伸区域20的宽度（图示Y）较佳范围约为20-120毫米。前面提到的大号训练裤，其宽度Y约为20-60毫米，更佳范围为40-56毫米，具体约为50毫米。在制做布网的单个宽度时，因为布网是从区域Y的中心切开的，弹力布片的未经机械延伸的外侧边沿部分51的宽度约为10-60毫米，前面提到的大号训练裤，Y约为10-30毫米，更佳为20-28毫米，具体约为25毫米。
每条弹力布片的长度L最佳约为50-190毫米。正如弹力布片的其他尺寸一样。长度L的选择必需考虑穿着者的具体身材尺寸，及合身舒适。上面提到的大号训练裤，长度L约为80-170，更佳约为100-160毫米。
一般制造的吸收套30是将吸收芯31置于不渗透液体的底层布32及能渗透液体的上罩布33之间，本发明的吸收套一般为矩形，具有侧边沿35a，35b，端部边沿36a，36b及前腰40、后腰41。
吸收芯31是一种普通的具有吸收性的物品，该芯件一般为：可压缩、适合的、对穿用者的皮肤无刺激，并具有吸收及留住液体如尿及其他一些人体渗出物的能力。吸收芯具有服装的外表，贴身表面，侧边沿及腰边沿，吸收芯可制造成各种规格及形状。（如，矩形，沙漏型，“T形”，不对称形等），并可由范围很广的吸湿材料制造，一般这些材料用作一次性使用的尿布和其他吸收物品，如一般称为气毡的粉碎的木浆。其它适用的吸收性材料的例子还有：绉纤维素填塞物，熔喷聚合物包括交联纤维素纤维;织物包括：织物卷、织物粘合布，吸收性泡沫，吸收性海绵，超吸收聚合物，吸收性凝胶材料或任何相当的材料或材料的组合物。吸收芯的构造及结构也是多样化的。（例如：吸收芯可以有不同的厚度区域，亲水梯度，超吸收梯度，或较低的平均密度和较低的平均基准重量吸收区域，或者也可包含一个或多个的层或结构）。吸收芯应有的总吸收容量是与设计负荷及尿布计划的用途等一致的。再者，吸收芯吸收容量的大小可以变化以适应使用者，从婴儿到成年人都行。
本发明的一具体实例中，吸收芯31包含两个不同的网或层，即包括一个吸收/分配芯及一个贮存芯（二者均未在图中示出）。吸收/分配芯位于上罩布及贮存芯之间，贮存芯位于吸收/分配芯及底层布之间，吸收/分配芯有一上表面，该表面的面积最佳是贮存芯上表面积的15%-170%，吸收/分配芯的位置最佳以贮存芯为基准，使吸收/分配芯的表面不延伸超出贮存芯的边界。虽然，粘结机构，例如：非硬化纤维素纤维，合成纤维，化学添加剂及热塑性纤维均能加入以增加网的物理完整性，但是吸收/分配芯最佳还是应包含一化学硬化的纤维素纤维网。贮存芯最佳应包含一超吸收材料及纤维材料的气流法纤维网，最好是气毡。可供选择的也是最好的，一块可渗透的布（例如，细薄布）或其他稀洋纱可以放置在吸收/分配芯及贮存芯之间，在处理及/或使用过程时可增加吸收芯的完整性。
吸收/分配芯的作用是快速收集人体排出的液体，快速从将液体开始接触处传送至吸收/分配芯的其它部分并暂时存贮这些人体排出的液体直至这些液体被贮存芯吸收为止。吸收/分配芯的分配功能特别重要，目的在于更充分地利用贮存芯的容量。因此，当吸收/分配芯可包括范围较大的各种吸收材料时，它最好包括能迅速地传送液体同时不致于受潮湿而破坏的纤维材料。其结果是吸收/分配芯既能有效地接受并分配再一次和接连的液体排泄，以及仅消耗极小量（＜2%）的超吸收材料。（由于吸收缓慢及凝胶堵塞）。
底层布32对液体（如尿）是不渗透的，虽然也可使用其它的不能渗透液体的柔韧的材料，但最好用薄塑料膜制造。此处所用的词“柔韧”涉及一种材料，该材料顺服并容易符合人体轮廓及形状。底层布阻止挤出在吸收芯中吸收和容纳的液体弄湿与尿布接触的物件如床单及内衣。底层布可以包括织造或非织造织物，聚合物薄膜如聚乙烯或聚丙烯热塑性薄膜，或者复合材料如薄膜涂布的非织造材料。用于底层布的热塑性薄膜具有的厚度范围最好约为：从0.012毫米（0.5密尔）至0.051毫米（2.0密尔）。
底层布32位于邻近吸收芯外套的表面，最好以该技术所熟知的附着方法连接在那里，例如，以均匀连续的一层胶粘剂，带有图案的一层胶粘剂或以胶粘剂形成分离的线、螺线、点的排列。已知令人满意的胶粘剂的制造者为：Century    Ad    hesive    Inc.    of    Columbus，Ohio其市场销售商品名称为Century    5227;还有H.    B.    Fuller    Company    of    Paul，Minnesota，其商品名称为HL-1258。附着连接的方法最好包括一种粘合剂细丝开式图案网络，如已公开的美国专利4，573，986其专利名称为“一次性使用接纳粪便的衣服”，专利人Minetola及Tucker专利批准日期4，3，1986，这里将其插入作为参考。细丝开式图案网络的示范性附着方法包括数根胶粘细丝盘绕成螺线形图案，所述是下列专利中所介绍的方法与装置的实例：美国专利号3，911，173，专利权人Spraque    Jr.批准日期7，10，1975;美国专利号4，785，996，专利权人Ziecker等批准日期22.11.1978;以及美国专利号4，842，666，专利权人Werenicz批准日期27，6，1989。上述各专利均已合并在这里作为参考。附着连接的方法包括以下可供选择的方案：热粘合，压力粘合，超声粘合，动力机械粘合，以及其他在现行技术中合适的附着连接或结合。
上罩布33具有顺服、柔软、对人的皮肤无刺激等特点。再者上罩布33能渗透液体，允许液体（如，尿）容易地渗透通过其厚度。可应用范围广泛的各种材料制造合适的上罩布如：多孔泡沫材料，网状的泡沫材料：有孔塑料薄膜，或织造及非织造的天然纤维网（例如，木或棉纤维），合成纤维（如，聚酯或聚丙烯纤维）或者是一种天然纤维与合成纤维的复合物。上罩布最好以亲水性材料或经过表面活性处理的疏水性材料制成。
上罩布33位于靠近吸收芯的主体表面并最好在该处以现行技术中熟知的连接方法（图中未示出）与底层布32连接。适当的连接方法已在关于底层布与吸收芯的连接中叙述了。在这里应用的词“连接”，包括组合，配置的意义，通过将一元件粘贴配置在另一元件上，以确保一元件直接对另一元件的牢固关系以及通过一元件粘贴配置在中间部件上，该中间部件挨次粘贴配置在另一元件上。
在本发明的一最佳实施方案中，上罩布及底层布在尿布周围相互直接连接，以及上罩布及底层布通过附着方法分别与吸收芯直接连接而形成它们之间的间接连接。
弹力布片10与前腰40及后腰41在裤套的每个边沿35a，35b上连接，因此它的未机械延伸的外侧边沿部分15为远侧的边沿。弹力布片10的内侧连接边沿17最好在上罩布33与底层布32之间与吸收套30连接，连接方法为将粘结剂18涂在内侧连接边沿17的任何一表面上，最好是涂在两个表面上。弹力布片的内侧连接边沿17可以有选择地连接在底层布及裤套中的其它结构或层之间，例如，图6所示，在底层布及一内侧弹力裤脚管口55之间。在一般情况下，在上罩布及底层布之间嵌入并连接的连接边沿的宽度范围约为5-20毫米，更佳的范围约为10-15毫米。可按照任何有效的方法涂抹粘结剂。比如连续地、间隔地、或者直线或者曲线，或是一盘绕图案。
最后，附着有弹力布片10的吸收套30沿大约纵向中心处42机械地折叠，因此使前腰40的贴身面34与后腰41的贴身面接近。然后附着在前后腰的相对的各弹力布片10的外侧边沿部分51的朝向人身的表面用封口52互相连接起来由此而形成一弹力侧翼5和制成训练裤。封口52制作时与吸收套的纵向边平行，或者稍有偏斜，如图5所示。封口52尽可能的薄以达到边缝50的宽度最小。最佳的封口方法是压力粘合封口，该方法使层粘布的各外侧边沿部分5的弹性层13粘合在一起。在一种最优的方法里，加工封口52的方法是：将外侧边沿部分通过一个转动的辊及一转动的压力辊之间，施加在多层布上的典型压力约为1500～5000公斤/厘米2。因此形成一条封口52线，该封口线一般宽度范围为1-10毫米，最佳是2-5毫米，粘合图案可能是连续的或断续的，及直的，曲线的或不规则的。最好是使用温度低于80℃，在环境温度下操作砧辊及压力辊就更好。也可应用更高的温度只要该温度适当地低于该弹性层材料的热塑熔隔温度，以及只要在该温度下弹力层本身不受损坏或削弱其性能。因此，选择压力、温度、粘合图案及应用封口工具的时间是在不使层粘布及其组成成份变坏的情况下，以使层粘布的弹性层的聚合材料的焊接最优化。边缝50也可用其它现行技术来实现。
边缝50完成后，封口处以外的地方有过剩的原料，可沿封口52外侧的线53修整，此外，侧翼的各部分也要修整，特别是围绕裤腿边缘，以便做到更加合身舒适，各个弹力布片10在接缝前或后可立刻一起修整，或者前后弹力片可以在附着于吸收套之前或之后分别修整。
本发明的训练裤可选择地包括通常使用的尿布及训练裤的其他特点及结构。这些可供选择的特点包括，但未被限制于：一次性使用的狭幅织物，在吸收套的前后腰部带有弹性腰及护肚片，一般位于沿吸收套各边，部分地围绕并在训练裤裤腿开口处封口的弹力外侧裤腿口，及弹力内侧隔离裤腿口;潮湿指示物;及在吸收套的两腿交叉处的弹力布片以便更合身舒适并可容纳人体排出液。
本发明的效果是提供一种具有弹力侧翼的训练裤，该弹力侧翼中具有改进的边缝。如压力封口形成的接缝在一般使用情况下具有足够强度可保持其封口状态，但当需要从穿着者脱去训练裤时，如裤被沾污后，人们可以很容易地将它撕开。
