Abstract
本发明的发明名称为透气且多微孔的热塑性薄膜。透气的热塑性膜、层压物、和制造膜的方法,该膜具有小于或等于15gsm的基重和至少大约500克水每24‑小时每平方米的水蒸气传输速率,其中所述膜具有大约小于10的MD断裂负载和CD断裂负载的比,以及至少大约5克的机器方向切口埃尔门多夫抗扯强度或者至少大约15克的机器方向切口梯形抗扯强度中的至少一个。
Description
本申请为国际申请号为PCT/US2015/030463、国际申请日为2015年5月13日、发明名称为“透气且多微孔的热塑性薄膜”的PCT申请于2016年11月11日进入中国国家阶段后申请号为201580027028.7的中国国家阶段专利申请的分案申请。
相关申请
本申请要求于2014年5月13日提交的美国临时专利申请号61/992,438、于2014年9月22日提交的美国临时专利申请号62/053,385、以及于2014年12月16日提交的美国临时专利申请号62/092,351的优先权。
技术领域
热塑性膜广泛用于个人护理产品,例如,作为尿布或其它一次性个人卫生用品的外层。由于各种原因,包括成本、舒适度、节约资源和最小化浪费,有需要尽可能使膜越薄越好,同时维持所述膜的其它必要性能。
热塑性膜需要的特点包括液体不可透性、蒸汽可透性(例如透气的)、可粘合至个人护理产品的其它层、以及有足够的物理强度可被处理成成品。当将热塑性膜用于包装(例如,用作消费品的外包装)时,强度是重要的考量。具有足够强度和基重的透气膜作为需要释放生产过程中产生的气味的产品的包装会尤其实用。
热塑性膜可通过将熔化的聚合组合物挤出到激冷辊(chill roller)上而形成,该过程中熔化的聚合组合物瞬间冷却以形成固态膜。膜的处理包括多个步骤,包括加热、冷却、以及拉伸来产生最终的膜产品,该膜产品的厚度比原始厚度小72倍或更小。在机器方向(MD)上拉伸形成高度定向型的薄型膜,这被称为机器方向定向(MDO)。MDO可以是实用的,然而也可影响尤其是更薄的膜的质量,例如降低横向方向(CD)的抗张强度、冲击强度、抗扯强度、和耐慢穿刺性(slow puncture resistance)。
背景技术
现有用于制造薄型热塑性膜的方法包括在美国专利7,442,332(Cancio et al)中描述的方法。在这个过程中,网的拉伸的大部分(超过一半)发生在所述挤出机模和第一轧点之间(比如在“熔化幕”内)。在这种浇铸过程中,两个缺陷是被称为“牵伸共振”的现象和膜内孔的形成,其中“牵伸共振”造成不均匀的膜厚度。这些问题随着生产速度增加而增加,且可进一步地限制可被应用的聚合组合物的种类。克服这些问题需要减慢生产,这最终导致成本提高。
因此,对于具有有限的MDO和需要的性质(比如没有孔、良好的透气性、良好的抗张强度和抗扯强度性质)、并且可被经济且高效地在高速生产线上生产的热塑性薄膜存在需求。
发明内容
通过提供具有低基重、大体上没有孔、且具有基重高得多的膜的物理属性特征的透气热塑性膜,本发明满足了上述的要求。本发明的膜表现出优秀的抗张强度、抗扯强度、和透气性。然而,抗张强度与膜的厚度成正比,一般更厚的膜表现出更高的抗扯强度,通过本发明的过程制成的膜表现出比针对具有相似厚度的相当的膜所预计的更高的抗扯强度。换言之,所述膜显示出抗扯强度与厚度的改进比例。
本发明的热塑性膜,其本身被视作独特的、通过新颖的流程制成,其中所述膜在某一温度下在MD上被拉伸,其中所述温度足够高来防止有害的MD定向,但低于热塑性聚合物的熔点。与描述在美国专利7,442,332中所述过程相反,这个过程发生在激冷辊的下游。本发明的方法允许所述挤出过程以常规生产速度发生,且不需要附加设备来减少牵伸共振。作为额外的优势,膜的质量(比如不透明度)可通过另外的下游MD拉伸控制,这会减少或消除了添加不透明剂的需求。

装置
图1描述膜形成装置10的示例设计,其适合形成本发明的膜。应用于膜或无纺织物材料的“机器方向”意味着当其在膜形成装置中处理时平行于膜或无纺织物的进行方向的方向。“横向方向”意味着垂直于机器方向的方向。在一个非限制性实施例中,并且如图1所述,膜形成装置10包括浇铸/拖拽工段12、机器方向定向(MDO)工段14、和横向交叉辊(CDI)工段16。可选择地,膜形成装置10可包括对于所属领域技术人员显而易见的附加工段,比如炼韧器工段、卷线机、附加的机器方向定向工段、和/或电晕处理工段。在其它实施例中,如同样将被所属领域技术人员理解的,其工段或部件的顺序可不同于描述于图1中的那些。
浇铸/拖拽工段12包括挤出机24,随后是至少一激冷辊28,其中第一缝隙26在挤出机和激冷辊之间。如将被所属领域技术人员理解的,挤出机24相对于激冷辊28的位置可从图1所示的位置改变至比所示的稍许更下游的位置,但其中挤出机24仍然在将包括挤出物的熔化幕沉积到激冷辊28上的位置。激冷辊28的下游(其具有温度T1并且以速度V1转动)是拉伸辊30,其具有温度T2并且以速度V2转动。激冷辊28通过第二缝隙32与拉伸辊30分离。在操作中,挤出机24熔化挤出物并将挤出物挤出穿过缝隙26至激冷辊28之上,形成网、或膜15。膜15穿过缝隙32进入轧点33,其中该轧点形成于从动辊34和拉伸辊30之间。膜15随后穿过空转辊39至机器方向定向工段14。
本发明的网或膜可通过被所属领域技术人员理解的方法形成,并且可被浇铸、吹制、压光、单独挤出、共挤出、冷浇铸、压印(nip embossed)、或任何其它的可使膜相容于此处所述的流程的方法处理。
在一个实施例中,热塑性聚合膜的配方可被混入挤出机24,例如在从大约210摄氏度到大约280摄氏度的温度下。准确的温度将取决于聚合组合物的配方。包括聚合组合物的网或“熔化幕”可被挤出(或共挤出,如果多层膜正在被形成)于激冷辊28上。激冷辊28的温度T1被精确地控制,以使得当膜15离开激冷辊28时,膜15处于足够高的温度使其在没有很大程度的MD分子定向的情况下拉伸至理想的厚度,但该温度低于聚合组合物的熔点。因此,温度T1和T2取决于膜的组分。T1可能大于80摄氏度、可替换地从大约80摄氏度到大约160摄氏度、可替换地从大约90摄氏度到大约160摄氏度、可替换地从大约100摄氏度到大约140摄氏度、可替换地从大约80摄氏度到大约120摄氏度、可替换地从大约100摄氏度到大约120摄氏度、以及可替换地小于160摄氏度。拉伸辊30的温度T2可大于40摄氏度、可替换地从大约40摄氏度到大约100摄氏度、可替换地从大约60摄氏度到大约100摄氏度、可替换地从大约60摄氏度到大约90摄氏度、可替换地从大约85摄氏度到大约90摄氏度、以及可替换地小于大约100摄氏度。
应注意在本发明中,激冷辊28的温度T1和拉伸辊30的温度T2显著高于任何之前公开的MDO流程。在之前的应用中,T1通常是从大约10摄氏度到大约60摄氏度,并且T2通常是从大约10摄氏度到大约40摄氏度。本发明使用平衡膜加工性和允许控制MDO的量的需求的温度。
在一个实施例中,至少有两根激冷辊,每一根均具有速度V和温度T。每根激冷辊的速度和温度可以是相同的或不同的,然而都将会足够使膜在没有很大程度上的MD分子定向的情况下被拉伸至理想的厚度,但该温度低于聚合组合物的熔化温度。仅通过非限制性例子的方式,温度将相差5摄氏度、10摄氏度、或更大。激冷辊可能每个各自是光滑的、有特定纹理的、涂覆的(例如利用释放处理),其中在每个辊上将相同或不同。
挤出机24和激冷辊28之间的第一缝隙26的长度是挤出机24和激冷辊28之间的最短距离,并且大于之前的铸造MDO流程。在一个实施例中,第一缝隙26的长度大于2.5厘米、可替换地从大约2.5厘米到大约25厘米、可替换地从大约3厘米到大约15厘米、以及可替换地从大约3厘米到大约7.6厘米。挤出物可在缝隙26中经历熔化幕拉伸,伴随着相应的厚度减少从10倍到大约25倍(大约10X到大约25X)。
在一个实施例中,如美国专利7,442,332中描述,装置可在挤出机24与激冷辊28之间包括附加的辊和轧点。在另一个实施例中,装置可包括一个或多个附加的激冷辊。在又一个实施例中,激冷辊28可以被两根辊取代,其中辊形成附加的轧点。辊可以是金属辊和橡胶辊,并且金属辊可选择地有压纹。在轧点中膜的温度是大约120摄氏度或以下,并且可替换地是大约100摄氏度或以下。在通过附加的轧点之后,膜前进穿过轧点33并且进一步经历此处描述的流程。
辊的速度比V2/V1提供膜拉伸的相对长度。因此,1/1(1x)的比指示了膜还没被拉伸。5/1(5x)的比指示了,在拉伸伴随着相应膜厚度减小之前,膜已被拉伸了其长度的5倍,即膜厚度是拉伸之前其厚度的0.2倍。在一个实施例中,V2/V1的比至少为2、可替换地至少为5、可替换地从大约2到大约8、可替换地从大约3到大约8、以及可替换地小于5。
在激冷辊28与拉伸辊30处的轧点33之间的第二缝隙32的长度是激冷辊28与拉伸辊30之间的最短距离,并且在一个实施例中为至少大约7.5厘米、可替换地从大约7.5到大约30厘米、可替换地从大约7.5到大约20厘米、可替换地从大约7.5到大约10厘米、可替换地大约30厘米、可替换地大约20厘米、可替换地大约15厘米、以及可替换地小于10厘米。在激冷辊28与拉伸辊30之间被拉伸后,膜15本质上是在MD上具有有限分子定向的无孔膜。
于此,“把有限机器方向定向传递于膜”意味着产生足够的MD定向来给予膜至少2.0牛/厘米的MD断裂负载与至少0.7牛/厘米的CD断裂负载。另外,膜将具有从大约1到大约15的MD断裂负载与CD断裂负载的比。虽然MDO的量将不会直接被量化,MDO的量相关于膜的性质。具有有限的MDO的膜将具有特别提升的CD性质(比如CD埃尔门多夫和梯形抗扯强度、CD抗张断裂强度)和相对于之前所述的膜的CD和MD抗张强度的提升的平衡。
从浇铸/拖拽工段12的下游,膜15可从拉伸辊30围绕空转辊39穿过达到第一及其方向定向(MDO)工段14。这个工段的目的是进一步在机械方向上拉伸膜,同时仍避免显著的MD定向。MDO工段14可包括加热辊35a和35b,随后是拉伸辊36a和36b和/或冷却辊37。在加热辊35a-35b处,膜15加热到温度T3。T3将取决于膜的组分,并且将足够避免显著的MD定向。在一个实施例中,T3是从大约80摄氏度到大约150摄氏度、可替换地大于95摄氏度、以及可替换地大于120摄氏度。
所属领域技术人员将理解,第一MDO工段14内的拉伸辊、加热辊和冷却辊的数量以及MDO工段的数量可以改变。因此,在可替换的实施例中,装置可包括一个或多个附加组的拉伸辊、加热辊、和/或冷却辊,来给予其理想的物理和美学特性,比如多孔性和不透明度。通过例子的方式,第二组加热辊、拉伸辊和/或冷却辊可位于第一MDO工段14中,拉伸辊36a和36b的下游和冷却辊37的上游。在可替换的实施例中,第二组加热辊、拉伸辊和/或冷却辊位于CDI工段16的下游、在第二MDO工段中。
膜15以V3的速度移向MDO工段14的下游。在一个实施例中,V3/V1的比大于1、可替换地大于2、可替换地小于25、可替换地从大约2到大约25、可替换地从大约5到大约15、可替换地从大约5到大约25。在一个实施例中,V3/V2和/或V2/V1的比大于1、可替换地大于2、可替换地小于5、可替换地从大约1到大约5、以及可替换地从大约2到大约5。
如果具有横向交叉辊(CDI)工段16,其可包括张紧辊38,随后是交叉辊40、42。在本发明中,交叉辊40、42被设计用于沿横向拉伸膜,导致附加的膜活化并且给予透气性。在一个实施例中,在CDI工段16之前或之后,机械方向交叉辊被用于替换横向交叉辊40、42处或另外地使用。合适的横向交叉辊在美国专利7,442,332中被描述。
替代在MDO工段和或CDI工段或除了这些工段之外,膜可以用拉幅架(未示出)被拉伸。这可被用于达到MDO与CDO的效果。
