Description

耐久的亲水纤维、织物制品及模制品
本发明涉及耐久的亲水纤维，更具体地说，本发明涉及耐久的亲水纤维，及由此而制得的织物制品和模制品，这种纤维适用作纸尿布、卫生巾等主要在卫生材料领域的表面材料，适用作吸水物品的保影品和保模品，还适用作工业揩布和医用揩布。
纸尿布或类似物由三层构成，即表面材料吸收材料及在穿用时皮肤与之接触的那一侧的底部材料。表面材料需具有透水性使被吸附的液体迅速转移到吸收材料中去，还需具有干触性使被吸收的液体不产生底流而赋予皮肤干的感觉。期待具有亲水性以改进透水性，也期待具有疏水性以改进干触性。为达到上述目的，使用了无纺织物，在其中往由聚烯烃或聚酯形成的纤维上粘附上少量表面活性剂(日本公开特许公报昭63-6166，及日本公开特许公报昭63-49158)。
在上述的由纤维制成并粘有表面活性剂的表面材料中，当液体被一次或再次吸附时，表面活性剂会流走，透水性迅速降低，使液体留在表面材料上，这导致产生不舒服感。已经知道这样一种材料，它减少了粘附在纤维上的表面活性剂的流走，而且甚至当水反复透过时其亲水性也不降低，这是一种由耐久亲水纤维形成的无纺织物，此纤维粘附有含有水溶性的改性聚硅氧烷的表面活性剂(日本公开特许公报昭63-303814，平1-148879，平1-148880，平2-169774及平3-59169)。
然而，虽然由粘附有表面活性剂的耐久亲水纤维所形成的无纺织构成纺织物在耐久亲水性方面是良好的，但还存在一个问题，即，因为水溶性改性聚硅氧烷被作为必要组份而含有，因而减少了纤维间的磨擦，构成纤维层压物(如无纺织物)的纤维产生滑动，纤维网强度降低，纤维层压物(例如无纺织物)的强度降低。还存在另一个问题，即，在所得织物制品这种货物的包缠过程中，因为织物制品间的平滑度是如此高，此货物的包缠形状是不稳定的。
在日本公开特许公报平3-50030中，推荐了一种把烷醇酰胺与具有活性氢的化合物的氧化烯添加剂或表面活性剂(如磷酸烷基酯)的混合物粘附到聚烯烃纤维上，以赋予亲水性的方法。但是，在这种方法中，其耐久亲水性并不足够，电阻不好。
因此本发明的目的是提供一种耐久亲水纤维，及由这种纤维制成的织物制品和模制品，它们具有比上述现有技术为高的耐久亲水性，它们减少了纤维之间的滑动面不降低纤维层压物例如无纺织物的强度。
本发明人进行了热心的研究以解决上述问题，结果是，通过把作为整理剂的特别的表面活性剂的混合物粘附到纤维的表面上，获得了可解决上述问题的前景，从而完成了本发明。
本发明具有下列组成部份：
(1)一种由用热塑性树脂制的纤维所组成的耐久的亲水纤维，往此纤维上粘附有0.2-1.0％重量的由下列表面活性剂(A)，(B)，(C)，(D)和(E)所形成的混合物：
(A)10-30％重量的一种或多种化合物，这些化合物选自碳数为28-50的高级醇或高级烷基胺的聚氧化烯添加剂，或选自由碳数为30-50的脂肪酸与多胺所形成的酰胺的聚氧化烯添加剂。
(B)10-30％重量的由碳数为20-28的脂肪酸与多胺所形成的酰胺的聚氧化烯添加剂。
(C)30-50％重量的由碳数为16-28的高级脂肪酸与烷醇胺所形成的酰胺，
(D)10-30％重量的碳数为10-22的磷酸烷基酯盐聚氧化烯添加剂，以及
(E)2-10％重量的碳数为12-16的烷基碳酸盐。
(2)根据权利要求1的耐久的亲水纤维，其中此纤维是复合纤维，在其中热塑性树脂中的至少两种组份以并列型或皮芯型进行排列。
(3)根据权利要求1的耐久的亲水纤维，其中，此纤维是复合纤维，在其中热塑性树脂中的至少两种组份以径向裂膜型或海岛型进行排列。
(4)根据权利要求1至3中的任一权利要求的耐久的亲水纤维，其中，构成纤维的热塑性树脂中的至少一个组份是聚烯烃树脂。
(5)根据权利要求1至3中的任一权利要求的耐久的亲水纤维，其中构成纤维的热塑性树脂中的至少一个组份是聚酯树脂。
(6)将根据权利1至5中的任一权利要求的耐久的亲水纤维通过混杂和/或粘合而制得的织物制品。
(7)将根据权利要求1至5中的任一权利要求的耐久的亲水纤维通过针织或织造而制得的织物制品。
(8)由根据权利要求1至5中的任一权利要求的耐久的亲水纤维单独一种或它们的混合物制得的模制品。
现将本发明进行详述。
作为用于本发明的热塑性树脂，可用聚烯烃基，聚酯基和聚酰胺基热塑性树脂的合并物作为例子。
在特别在卫生材料领域使用这些材料作为表面材料的领域，聚烯烃基和聚酯基热塑性树脂是优选的。
聚烯烃基树脂是乙烯或丙烯的均聚物，或者是乙烯或丙烯与其他α-烯烃的结晶共聚物，或者是它们的混合物。α-烯烃共聚物包括主要包含丙烯的α-烯烃共聚物或三聚物。这些共聚物的例子包括例如主要包含丙烯的乙烯或丁烯-1或4-甲基戊烯-1的共聚物。作为聚酯基共聚物，作为例子的是聚对苯二甲酸乙二醇酯，聚对苯二甲酸丁二醇酯，(对苯二甲酸乙二醇酯-间苯二甲酸乙二醇酯)共聚物，或聚醚酯。
聚酯基树脂或聚酰胺基树脂与聚烯烃基树脂的混合物可根据用途而适当选择。
在这些热塑性纤维中，为达到本发明目的，可将具有别的功能的添加剂在一定用量范围内加至此纤维中，这些添加剂可根据用途进行选择并合适地合并。
包含用于本发明的表面活性剂组成的(A)，(B)，(C)，(D)和(E)的混合物(以下称整理剂)描述如下：
(A)：选自碳数为28-50的高级醇或高级烷基胺的聚氧化烯添加剂，或碳数为30-50的脂肪酸与多胺所形成的脂肪酸酰胺的聚氧化烯添加剂的一种或多种化合物。
高级醇或高级烷基胺的聚氧化烯添加剂是可含有碳数为28-50的侧链的饱和或不饱和醇或胺的烯化氧添加剂。如果碳数小于28，则难于获得足够的耐久亲水性。脂肪酸酰胺的聚氧化烯添加剂同样是可含有碳数为30-50的饱和或不饱和脂肪酸与多胺(例如乙二胺，二乙三胺，三乙四胺等，或二乙基乙二胺，氨乙基乙醇胺等)的烯化氧添加剂。如果碳数小于30，则难于获得足够的耐久亲水性。若碳数大于50，则成本增大，因而不适于实用。
聚氧化烯基包括烯化氧(例如环氧乙烷，环氧丙烷，环氧丁烷等，特别是单独的环氧乙烷或环氧乙烷与环氧丙烷)的无规或嵌段共聚物，添加剂摩尔数为2-20摩尔，优选为5-15摩尔，共聚的环氧丙烷的摩尔数与环氧乙烷的相等，或优选小于此值。
(A)的加入数为10-30％重量，优选为15-25％重量。如果小于10％重量，则不能获得耐久亲水性。如果超过40％重量，则溶液粘度变得如此高，以致溶解度变差。
(B)碳数为20-28的脂肪酸酰胺的聚氧化烯添加剂
此高级脂肪酸酰胺的聚氧化烯添加剂是脂肪酸单酰胺或脂肪酸二酰胺，是由可含有碳数为20-28的侧链的饱和或不饱和脂肪酸(例如aragin酸，山嵛酸，二十四烷酸，二十九烷酸等)与多亚乙基多胺(例如乙二胺，二乙三胺，三乙四胺等，或二乙基乙二胺，氨乙基乙醇胺等)之间的惯用反应而获得的。如果碳数小于20，则耐久亲水性差；而如果超过28，则起初的亲水性差。
聚氧化烯基优选是5-30摩尔烯化氧(特别是环氧乙烷)，例如环氧乙烷，环氧丙烷，环氧丁烷等的基。如果环氧乙烷的摩尔数小于5，则溶解度降低；而如果超过30摩尔，则织物制品的液体传送变慢。
组分(B)的加入量为10-30％重量，更优选为15-30％重量。如果低于10％重量，则得不到所希望的耐久亲水性。如果超过30％，则织物制品的吸水速度变慢。
表面活性剂(C)：一种包含碳数为16-28的高级脂肪酸及烷醇胺的酰胺。也就是说，它是通过可具有碳数为16-28的侧链的饱和或不饱和脂肪酸与烷醇胺(例如-乙醇胺，二乙醇胺，一异丙醇胺等)之间的惯用反应而制得的，特别适用的烷醇酰胺是高级脂肪酸例如硬脂酸，油酸，山嵛酸，芥酸等与二乙醇胺之间的以2∶1至1∶2(当量比)的反应混合物。如果碳数小于16，则不能获得足够的耐久亲水性，而如果大于28，则成本增大，这不适于实用。
组分(C)的加入量为30-50％重量，更优选为30-45％重量，如果小于30％重量，则耐久亲水性降低。如果超过50％，则在梳理过程等中，产生针筒包缠，降低平整度。
对于上述的三种表面活性剂(A)，(B)和(C)，HLB(亲水-亲油平衡值)为2-19，优选为5-15是适用的，但它取决于被混合的阴离子表面活性剂的亲水性。
(D)：碳数为10-22的磷酸烷基酯盐的聚氧化烯添加剂。在聚氧化烯磷酸烷基酯盐中，烷基优选是饱和的或不饱和的完全中性盐，它可以具有碳数为10-22，优选为10-14的，例如癸醇，月桂醇，肉豆醇的双磷酸酯或单磷酸酯的侧链，聚氧化烯基是烯化氧例如环氧乙烷，环氧丙烷，环氧丁烷等(特别是单独的环氧乙烷)，或环氧乙烷与环氧丙烷的无规或嵌段共聚物。所加成的摩尔数，在单独环氧乙烷的情况时，是2-10摩尔，更优选为3-7摩尔。
此中性盐包括碱金属盐例如K，Na盐等，铵盐或胺盐，但就电阻而言优选K盐或Na盐。如果醇的碳数小于10，则纤维与金属间的摩擦增大，降低梳理传递，导致在园筒中包缠。此外，如果超过22，则电阻降低。
组分(D)的加入量为10-30％重量。如低于10％重量，则电阻不足够；而如果超过30％重量，则耐久亲水性降低。
表面活性剂(E)是碳数12-16的烷基碳酸盐此烷基碳酸盐(E)特别能获得优异的电阻，其例子包括石油碳酸Na盐，和烷基苯磺酸Na盐，就与纤维的亲合而言，碳数为12-16的石油磺酸Na盐是优选的。
(E)的合适用量为2-10％重量，更优选为5-10％重量，如果超过10％重量，则在梳理过程中导致园筒包缠及粘附到织物制品上。
粘附到根据本发明的耐久亲水纤维的整理剂，优选的是将表面活性剂(A)，(B)，(C)，(D)和(E)在上述的合适用量范围内进行混合，它至少占全部添加剂的85％或更多。应该注意，除了上述5种表面活性剂外，其他惯用的表面活性剂，根据构成纤维，织物制品及模制品的热塑性树脂，可在不影响本发明目的的用量范围内加入。
此整理剂粘附到上述热塑性纤维上的数量是0.2-1.0％重量，更优选为0.3-0.7％重量。
如果粘附量小于0.2％重量，则电阻及耐久亲水性不足够，而如果超过1.0％重量，在梳理过程中会导致园筒包缠及粘附到织物制品上。
对于把整理剂粘附到热塑性纤维上的方法没有特别的限制，但公知的方法，例如通过与油辊接触，浸于浸泡桶或在纺纱或拉伸过程进行喷涂使之粘附的方法，或通过在加工成为纤维层压物例如纤维网，织物制品(例如无纺织物)或模制品之后用接触法，浸涂法和喷涂法使之粘附的方法，均可使用。
根据本发明的耐久亲水纤维，通过把整理剂粘附到热塑纤维而制得，而它的横截面结构可以是单一结构或复合结构。此外，根据用途，此纤维形状可以是短纤维，长纤维，或者是卷曲的或不卷曲的纤维，或者是它们的混合。
在整理剂的功能方面，裂模型复合纤维在高压水流加工中的行为将描述如下。
通常，在例如由疏水热塑性树脂形成的径向裂膜型复合材料中，以纤维整理剂的形式粘附到其表面的普通亲水表面活性剂，在采用高压水流法形成无纺织物的过程中迅速被洗去。因为这些纤维本身是极疏水的，在用高压水流加工成为无纺织物过程的开始阶段，纤维避开水流，不能平稳地获得水的震动能。因此，不能获得足够均匀细分的极细纤维无纺织物，除非增加高压水流出现的次数。
另一方面，在粘附到根据本发明的整理剂的径向裂膜型复合纤维中，与通常情况相似，此纤维本身由极疏水热塑性树脂形成。然而，因为粘附到纤维表面上的本发明的整理剂的不连续很轻微，其亲水性能足够保持。甚至当高压水流加工成为无纺织物的过程重复时，纤维仍能接受水的震动能，不避开水流，在高压水流出现次数较少时仍能制得足够均匀细分的极细纤维无纺织物。
此外，本发明的耐久亲水纤维，因为在湿加工例如造纸中，整理剂在水中的不连续很轻微，因此甚至在使用疏水树脂例如聚烯烃基树脂时，纤维的亲水性得以维持，其在水中保持分散的性能优异。
用通常的方法制造使用本发明耐久亲水纤维的织物制品。例如，获得无纺织物的一种方法包括：用干法或湿法把短纤维制成纤维层压物，用热辊或超声波、热空气熔融等方面进行挤压，用高压水流或针使纤维混杂。另一方法包括使用纺纱，连续纱或类似物，通过针织或织造的方法以获得无纺织物。
此外，本发明的目的通过将整理剂粘附到刚制得的织物制品上而达到，这些织物制品例如是根据上述方法的织物制品，或者用纺丝成布法，喷熔法，冲洗纺纱法或类似方法制得的织物制品。此外，可通过在根据本发明耐久亲水纤维之外切割排列成并列型、皮芯型、径向细分型和海岛型的复合纤维，将它与吸水材料例如纸浆和高分子吸附树脂混合，以及对它进行处理，而赋予保持吸附剂形状的性能。通常，热塑性复合纤维引起吸附剂的吸水性能降低，减少掺混棉的比例。然而，由于本发明的耐久亲水纤维保持亲水性，吸水性能仅稍稍降低。
根据本发明的耐久亲水纤维，织物制品及模制品可作为表面材料用于保持材料的广泛领域，用作如上所述构成的卫生材料领域的吸附剂，医用或工业用揩布，吸附衬垫，以及民用工程的结构领域中的增强建筑结构的纤维，液体运输膜，排水设备，透水片，等等。
                    实施例
以下将对本发明作详细描述，但此发明不限于下列实施例和比较实施例(就它们不超过本发明的要点而言)。
在实施例中，使用下列性能评价法。
(1)电阻性能：在温度20℃和相对湿度45％的条件下，用梳理检测机以7米/分的速度把40克样品纤维加工成纤维网，测定产生在此网中的静电电压，以便按下到参考标准进行评估。如果电压小于100伏，则断定可以实用。
                    ○：小于100伏
                    △：100伏或大于100伏，但小于500伏
                    ×：500伏或大于此值
(2)梳理通过性：在温度30℃和相对湿度80％的条件，用微型梳理检测机以7米/分的速度，把40克纤维材料制成纤维网。然而，把梳理检测机停下，观察园筒，以便按下列参考标准进行评估：
                    ○：无包缠
                    △：部件包缠
                    ×：几乎全部被包缠
(3)网的状态：用上述方法制的网的状态按下列参考标准进行评估。
                    ○：无棉结，具有张力且平整
                    △：部分有棉结

(4)纤维的亲水性，将用梳理机或类似物制出的5克样品纤维装入直径为3cm，长8cm，重3g的铜丝制的笼中。把此笼静静地漂浮在装水容器的水平面上，水温25℃，测定直到样品和笼沉入水中的时间，马上把沉下的样品自水中取出，离心脱水，并在室温下在空气中干燥24小时，测定在相同操作中的沉下时间。这一测定重复3次作如下判断：如果沉下时间小于10秒，则亲水性良好，而如果第3次测定值也小于10秒，而耐久亲水性也为良好。
(5)织物制品的耐久亲水性：把30g/m2(单位面积的重量)的织物制品切成10cm×10cm，把它放在市场购得的纸尿布上，此纸尿布上放有内径为6cm的筒。
往此筒中倒入65ml水，使织物制品吸收纸尿布中的水。倒入水之后3分钟，把织物制品放在上下两滤片(Toyo Rosi，No.50)之间，放上一块板(10cm×10cm)及重量为3.5kg的法码。放置3分钟并脱水，然后在空气中干燥5分钟，把所得的织物制品放在滤片(Toyo Rosi No.50)上。通过吸移管从织物制品上1cm处滴入盛在保温瓶中的23°±2℃的水(共20滴)，在滴水的同时不断改变位置，测出在10秒或小于10秒内织物制品表面上消失的水滴数，把已测的织物制品放在市场购得的纸尿布上。此相似操作重复进行三次。
(6)触感：由10位检测人通过官能检出测定织物制品样品的触感，以便按下列参考标准进行评估：
