具体实施方式
本发明的针织面料仅一面具有凸条结构,相邻凸条之间有沟槽。与凸条延伸方向平行的方向为纵向,与凸条延伸方向垂直的方向为横向。本发明的针织面料的组织没有特别限定,可根据需要进行选择,只要能在一面上形成凸条结构即可。本发明中,组织优选为变化平针组织。这里的变化平针组织由成圈、浮线复合而成,至少连续3纵行浮线编织形成空心凸条结构。当液体滴在凸条结构面上时,纵向上的扩散阻碍要比横向上少得多,扩散优势明显。当液体滴在另一面上时,凸条底部的空心结构使得液体沿横向扩散的渠道减少,而纵向的扩散渠道并没有受到任何影响,扩散优势明显,所以本发明的面料无论是哪一面都能实现纵向吸水扩散长度大于横向的目的。本发明中凸条高度h、凸条宽度a和沟槽宽度b满足如下关系:1.0≤h/(a+b)≤8.0,更优选1.0≤h/(a+b)≤3.0。如果h/(a+b)<1.0,纵横向之间的吸水扩散长度差不明显,即液体单向扩散优势不明显,而且保水性差;如果h/(a+b)>8.0,不论哪一面作为肌肤面使用,舒适感都会降低,特别是凸条吸收液体之后,湿感加重,还会产生粘腻感,干爽性差。
作为优选,沟槽宽度b与凸条宽度a满足如下关系式:1.0≤b/a≤12.0,进一步优选1.0≤b/a≤7.0,最优选1.0≤b/a≤3.0。如果b/a小于1.0的话,单位面积内液体沿纵向扩散的渠道减少,纵横向之间的吸水扩散长度差有变小的趋势,因此不作为优选;如果b/a大于12.0的话,液体主要在沟槽处扩散,同样,纵横向之间的吸水扩散长度差有变小的趋势,因此不作为优选。
作为优选,凸条高度h为1000~10000μm,进一步优选为1000~5000μm,最优选为1000~3000μm。当凸条高度低于1000μm时,面料保水量有下降的趋势,因此不作为优选;当凸条高度高于10000μm时,面料整体厚度提高,有可能会影响到穿着舒适性,因此不作为优选。
作为优选,凸条宽度a为100~5000μm,进一步优选为100~2000μm,最优选为500~1000μm。当凸条宽度小于100μm时,凸条排列紧密,凸条结构面接近于平针组织 外观效果,纵横向之间的吸水扩散长度差有变小的趋势;当凸条宽度a大于5000μm时,面料的保水量有下降的趋势,而且有可能出现反渗的问题。
作为优选,沟槽宽度b为100~5000μm,进一步优选为100~2000μm,最优选为500~1100μm。当沟槽宽度小于100μm时,液体在非凸条面上沿纵向扩散的渠道减少,纵横向之间的吸水扩散长度差有变小的趋势;当沟槽宽度大于5000μm时,单位长度内凸条的个数减少,有可能会影响到面料的保水量。
本发明的针织面料由亲水性纤维和疏水性纤维构成,作为优选,本发明凸条结构的纤维为亲水性纤维。这里的亲水性纤维为本身具有亲水性能的纤维或者为表面附着有亲水树脂的纤维,优选本身具有亲水性能的纤维,如天然纤维中的棉纤维,再生纤维素纤维中的粘胶纤维、莫代尔纤维等,合成纤维中的聚酰胺纤维等,更优选棉纤维或粘胶纤维。这里的疏水性纤维为本身不具备亲水性能的纤维或者为表面附着有拒水树脂的纤维,优选为本身不具备亲水性能的纤维,如聚对苯二甲酸乙二醇酯纤维(PET)、聚对苯二甲酸丁二醇酯纤维(PBT)、聚对苯二甲酸丙二醇酯纤维(PTT)、阳离子染料可染聚酯纤维(CDP)、聚丙烯纤维(PP)、氨纶(PU)等中的一种或多种,优选至少含有PET纤维,更优选至少含有PET纤维和氨纶。本发明所用纤维的形态没有特别限定,可以是长丝或短纤纱,根据需要选择即可。
作为优选,本发明的针织面料纵横向吸水扩散长度比为1.2以上,保水量为700g/m2以上。更优选纵横向吸水扩散长度比1.5以上3.0以下,保水量为900g/m2以上3000g/m2以下。
本发明的针织面料可以是白坯,也可以是着色的产品。作为着色的产品可以是通过使用色纱编织而得到,也可以是通过对白坯进行染色加工后得到。
本发明的生理用品至少包括防漏部品,防漏部品至少包括防水层、吸水扩散层和肌面层,吸水扩散层至少含有前记针织面料,且针织面料的凸条结构面朝向防水层。
本发明的生理用品可以是仅由防漏部品构成的生理护垫、防溢乳垫,也可以是由防漏部品与大身等构成的生理内裤,没有特别限定。
这里的肌面层为与肌肤接触的表层,起到快速渗透的作用。作为优选,肌面层为至少一面具有90°~180°的静态接触角(与水的静态接触角)的防水性面料,肌面层可以是防水性网眼面料或防水性非网眼面料。更优选,防水性网眼面料为至少一面具有130°~180°的静态接触角的网眼面料;防水性非网眼面料为至少一面具有90°~130°的静态接触角的非网眼面料,非网眼面料的组织可以是普通平针、变化平针等。最优选,肌面层为双面具有130°~180°的静态接触角的防水性网眼面料,这样既能保证水分渗透到下一层,也能同时防止吸收的液体不会因为外力挤压而反渗到肌面层,降低产品的反渗率,提高肌面的干爽性。前记防水性面料没有特别限定,可以是经过浸轧拒水剂得到的面料,拒水剂的成分可以列举的是硅氧烷类化合物、碳氢类化合物等。
一般来说,肌面层越厚,吸液能力越强,液体越容易被存储在肌面层中,但是出现外 力挤压时,这些存储在肌面层中的液体就有可能被挤出来,影响穿着体验,因此本发明优选采用克重60~130g/m2的防水性面料,这样可以降低反渗率。
与肌面层相邻的是吸水扩散层,吸水扩散层可以仅由本发明的针织面料构成,也可以由本发明的针织面料与无纺布共同构成,优选仅由本发明的面料构成。吸水扩散层由本发明的针织面料与无纺布共同构成时,虽然吸水性得到提高,但生理用品的厚度有所增加,有可能引起不适感,因此不作为优选。
作为优选,本发明的针织面料的凸条结构面朝向防水层,这样的话,可以保证穿着舒适性。
作为优选,根据JIS L 1902:2015菌液吸收法的测试,前记肌面层、吸水扩散层中至少一层的静菌活性值大于2.2。抗菌性可以是通过采用抗菌纤维或抗菌后整理得到。这里的抗菌纤维是指将含银等的陶瓷粉混入聚合物中进行纺丝得到,抗菌后整理是指利用季铵盐等抗菌剂进行浸轧或浴中处理。
为了提高运动追随性,防水层优选为经向伸长率在30%~100%之间的涂层面料或贴膜面料。这里涂层面料没有特别限定,可以是涂布聚氨酯(PU)或聚四氟乙烯(PTFE)等树脂的单面涂层面料。这里的贴膜面料也没有特别限定,可以是贴有PU膜或者TPU膜的单面贴膜面料。防水层的涂层面或贴膜面与吸水扩散层相邻。
作为优选,防漏部品的肌肤面的吸水速度大于1.0ml/s,更优选吸水速度大于5.0ml/s,这样可以保证肌面的干爽,并有效防止侧漏。
作为优选,本发明的防漏部品的吸水量为15~50g/100cm2
本发明的防漏部品可采用外包法进行缝合,这样可以防止液体从侧面渗出。作为优选,本发明的防漏部品的反渗率在5.0%以下,具有优异的防反渗效果。
下面结合实施例及比较例对本发明做进一步的说明。
本发明中所涉及的各参数的测试方法如下:
(1)凸条高度、凸条宽度、沟槽宽度
首先,按照面料的编织纹路,沿与凸条延伸方向垂直的方向剪取1.0cm*0.5cm的样布三块。接着,取其中1块样布并将其在自然无张力的状态下粘贴在金属凸形样品台上(面料的凸条延伸方向垂直于凸形样品台的表面),然后使用KEYENCE(基恩士)VHX-2000C显微镜观察样布的横截面。具体为:将显微镜倍率调至50倍,对观察处进行深度合成并3D显示。选取其中一个凸起,分别找出其两侧底端与非凸起部分之间的连接线圈的外侧,两个连接线圈的外侧之间的直线距离a即为凸条宽度;两个相邻凸条之间的直线距离b即为沟槽宽度。凸条宽度a所在的延伸线为直线e,再选取凸条的最高点,其与直线e之间的垂直距离即为凸条高度h。按照此方法分别对样布的横截面上的10处进行测量,分别得到凸条宽度1组数据、沟槽宽度1组数据、凸条高度1组数据,每组数据中去除最大的两个数值和最小的两个数值,得到中间的6个数值,再分别计算出每组数据的平均值。按照同样的方法对余下2块样布进行测量、计算,将3块样布的数据取平 均值作为本发明的凸条宽度a、沟槽宽度b以及凸条高度h。
(2)纵横向吸水扩散长度比
与凸条延伸方向平行的方向为纵向,与凸条延伸方向垂直的方向为横向。从面料上剪取18cm*24cm(横*纵)的样布3块,取其中1块样布将3mL三级水滴在非凸条结构面上(滴下时滴管垂直接触面料,不施加压力,1秒内全部滴下),10分钟后用刻度尺量出纵向上的扩散长度记为M、横向上的扩散长度记为N,计算出比值M/N。如果扩散长度看不清,可用0.1g染料和20mL水混合均匀后的混合液代替三级水。按照同样的方法对余下的2块样布进行测量,得到3组数据取平均值作为本发明纵横向吸水扩散长度比。
(3)表里保水率比
a.取10cm*10cm的样布3块,并取同样大小的滤纸6块,取同样大小的有机玻璃1块;
b.在温度20±2℃、湿度65±4%的环境下,调温调湿24小时;
c.先称量出有机玻璃(W0)和1块样布的重量(W1)(保留小数点后三位),再用注射器量取1mL的三级水置于有机玻璃上,并将称重好的样布迅速置于水上(非凸条结构面接触水),放置1分钟后,称量出吸水后样布的重量(W2)(保留小数点后三位),称量出吸水后有机玻璃的重量(W3)(保留小数点后三位);称量出吸水前两片滤纸的重量(w1、w3)(保留小数点后三位)。接着,将吸水后的样布(以非凸条结构面为表面,表面朝下放置),放在前记两片滤纸的中间,并在此上面放置500g的重物,放置1分钟后,直接称量出表面滤纸和里面滤纸的重量(w2、w4)(保留小数点后三位),通过以下公式计算出表里保水率比(保留小数点后一位),
表面保水率(%)=(w2-w1)/(W2-W1)×100
里面保水率(%)=(w4-w3)/(W2-W1)×100
表里保水率比=表面保水率(%)/里面保水率(%)
W1:吸水前的样布的重量(g)
W2:吸水后的样布的重量(g)
w1:吸水前表面滤纸的重量(g)
w2:吸水后表面滤纸的重量(g)
w3:吸水前里面的滤纸的重量(g)
w4:吸水后里面的滤纸的重量(g);
d.按照步骤c的方法对余下2块样布进行测量,取平均值作为本发明的表里保水率比。
(4)保水量
与凸条延伸方向平行的方向为纵向,与凸条延伸方向垂直的方向为横向。取6cm*27cm(横*纵)的样布3块,样布应平整无褶皱。将样布放置在标准大气压条件下调湿平衡,分别称取样布的原始重量(m1)(保留小数点后三位)。取其中1块样布将其放入盛有三级水的容器内,样布吸水后自然下沉。如样布不能自然下沉,则可将样布压至水中后抬起,反复2~3次。样布在水中完全浸润10分钟后取出,自然平展地垂直悬挂(沿横向夹住, 纵向自然下垂),样布中水分自然下滴;注意观察,当样布不再滴水时,立即用镊子夹取样布并称出样布的重量(m2)(保留小数点后三位)。注:当两滴水的时间间隔不低于30秒,即可认为样布不再滴水。通过以下公式计算出样布的保水量(精确到整数),保水量(g)=m2-m1。按照同样的方法对余下2块样布进行测量,取平均值作为本发明的保水量。
(5)伸长率
从防漏部品中拆解出防水层,再根据JIS L 1096:2010伸长率D法进行测试。
(6)静菌活性值
从防漏部品中拆解出吸水扩散层中的针织面料,再根据JIS L 1902:2015菌液吸收法进行测试。
(7)静态接触角
从防漏部品中拆解出肌面层,再根据座滴法进行测试。剪取5cm*5cm样布1块,使用LAUDA接触角测量仪,在样布的一面上任意选取3个位置进行测量,注意液滴滴下5秒之内完成测试,得到3个数据,取平均值作为本发明面料的一面上的静态接触角。
(8)吸水速度
将防漏部品拆解,每层分别剪取10cm*10cm的样布各3块,即3组样布。每层各取1块样布并按照各层在生理用品中的顺序叠放好,接着将四周包裹防水胶带,胶带距离四周边缘各0.5cm,然后在距离肌面层表面(肌肤侧)1cm高处滴加5ml的三级水,从水滴接触样布表面开始计时直到水滴在样布表面消失的时间记为T,滴加的5ml水(5g)与液体被吸收的时间的比值即为吸水速度,计算公式如下:吸水速度(ml/s)=5/T。按照同样的方法测出余下两组样布中的吸水速度,取平均值作为本发明的吸水速度。
(9)反渗率
将防漏部品拆解,每层分别剪取10cm*10cm的样布各3块,即3组样布。每层各取1块样布并按照各层在生理用品中的顺序叠放好,接着将四周包裹防水胶带,胶带距离四周边缘各0.5cm,然后在距离肌面层表面(肌肤侧)1cm高处滴加5ml的三级水,吸液30秒后,再在润湿了的表面垫一张滤纸(事先称量重量并记为G1),放上1块10cm*10cm的亚克力板,随后增加50g/cm2的荷重,在滤纸吸收水分后,称量滤纸吸液后的重量并记为G2,计算滤纸从肌面层上吸走的水分的重量G=G2-G1,该重量与滴加的5ml水(5g)重量的比值即为反渗率,计算公式如下:反渗率(%)=[(G2-G1)/5]*100%。按照同样的方法测出余下两组样布的反渗率,取平均值作为本发明的反渗率。
(10)防漏部品的吸水量
将防漏部品拆解,每层分别剪取6cm*27cm的样布各3块,即3组样布。每层各取1块样布并按照各层在生理用品中的顺序叠放好,接着将四周包裹防水胶带作为待测样品,胶带距离四周边缘各0.5cm,然后在距离肌面层表面(肌肤侧)1cm高处滴加5ml的三级水,1分钟后,将样品倾斜45°角看是否有液体漏出,重复5ml/次×多次(漏了就停止),计算漏之前滴下的三级水的总量,即为防漏部品的的吸水量。
(11)舒适度(实际穿着效果自我申告)
根据实际穿着时的舒适感进行打分评级。受试人数为10人,舒适感评分标准为0~100分,将10人的打分结果取平均值作为穿着舒适感的得分,根据得分进行评级:
1.舒适(76~100分):○
2.比较舒适(51~75分):△
3.不舒适(0~50分):×。
(12)防侧漏效果(目视法)
将防漏部品拆解,每层分别剪取6cm*27cm的样布各1块。将每层的样布按照各层在生理用品中的顺序叠放好,接着将四周包裹防水胶带作为待测样品,胶带距离四周边缘各0.5cm。然后在距离肌面层的表面1cm高处滴加10ml(约两次经期量)的三级水,1分钟后,将样品倾斜45°角看是否有液体漏出。如果侧边没有液体漏出的话,则判定为○;侧边有液体漏出的话,则判定为×。
