Description

针织面料及其用途 技术领域
本发明涉及一种针织面料及其用途，具体涉及一种具有调温调湿功能的针织面料及其用途。
 背景技术
当今社会，随着生活水平的不断提高，消费者在服装的穿着舒适性和功能性方面上的需求也在日益增强。另外，人们通常会根据天气的冷热程度增加或减少衣服以实现调温调湿的目的，但这样的做法不但麻烦，而且有时很难实现，尤其在休闲、运动领域更为突出。
为此，人们进行了很多研究。如，日本专利文献特开2004-316005中公开了一种有吸湿发热性能的纤维构造物，并具体公开了该纤维构造物是由具有吸放湿性能的素材构成，纤维表面附着有温感刺激性物质，可以增强血液循环，因此，该纤维构造物具有更加优异的保温性和吸湿性，主要用于冬天的保暖性服装等，但无法实现调温调湿冬夏两用的目的。
又如，中国专利文献CN103584385A中公开了一种凉爽保暖两用的服装，并具体公开了由凉爽层与保暖层上下连接构成，凉爽层采用超细仿真丝，保暖层采用超滑仿毛绒，凉爽层和保暖层之间采用棉线缝合在一起，虽然获得了凉爽保暖两用的特性，但由于凉爽层与保暖层是通过棉线连接的，多次洗涤后棉线易断，耐久性有待进一步提高。
又如，中国专利文献CN204994641U中公开了一种吸湿发热抗静电毛衫，并具体公开了面料外层由抗静电锦纶纤维构成，内层由吸湿发热腈纶纤维构成，领口部位由驱蚊再生纤维素纤维构成，纽扣由磁疗石构成，其中，抗静电锦纶纤维中添加有炭黑等导电物质，由于这些纤维原料吸热性强，比较适用于秋冬季节，并不能实现调温调湿冬夏两用的目的。
 发明内容
本发明的目的在于提供一种具有调温调湿功能且耐久性优越的针织面料及其用途。
为了实现上述目的，本发明的技术解决方案如下：
本发明的针织面料为包括面A和面B的双面构造，其中，面A的吸湿率差ΔMR A和面B的吸湿率差ΔMR B满足如下关系式，
（ΔMR A+ΔMR B）/2≥0.5，
|ΔMR A-ΔMR B|≥0.1。
本发明的针织面料由于面A和面B之间存在有特定的吸湿率差的关系，因而具有优越的调温调湿作用，无论是在炎热的酷暑，还是在寒冷的冬天都可以穿着使用，而且耐久性极佳，可广泛用于制作内衣、T恤等。
 附图说明
图1为本发明实施例1的空气层组织编织图。
图2为本发明实施例15的变化组织编织图。
图3为本发明实施例20的空气层组织编织图。
图4为本发明实施例21的空气层组织编织图。
  具体实施方式
众所周知，纤维材料从气态环境中吸着水分的能力称为吸湿性。吸湿是一个动态的过程，即纤维在不断地吸收水汽的同时，又不断地向外放出水汽。
本发明的针织面料为双面构造，包括面A和面B, 其中，面A的吸湿率差ΔMR A和面B的吸湿率差ΔMR B满足如下关系式，
（ΔMR A+ΔMR B）/2≥0.5，
|ΔMR A-ΔMR B|≥0.1
其中，
ΔMR A=面A在30℃、90%RH时的平衡吸湿率-面A在20℃、65%RH时的平衡吸湿率，
ΔMR B=面B在30℃、90%RH时的平衡吸湿率-面B在20℃、65%RH时的平衡吸湿率。
这里的平衡吸湿率是指当纤维材料在特定的大气条件下，吸、放湿作用达到平衡稳定时的回潮率，也称为平衡回潮率。面料的ΔMR越高，中等强度运动（如快走、跳舞）时服装内的水蒸气压越低,闷热感越小,舒适性越好。
本发明的针织物为双面构造，包括面A和面B。这是考虑到，当面料为双面构造时，两面可以实现不同的ΔMR，随着室内外温差和气压差异的变化，从不同的温湿度环境进入另外一个温湿度环境时，会使衣服内的气候微循环发生变化。
当（ΔMR A+ΔMR B）/2＜0.5、|ΔMR A-ΔMR B|＜0.1时，面料两面的吸湿性都较差，不能带来调温调湿的作用。因此，本发明中要求（ΔMR A+ΔMR B）/2≥0.5，优选1.0～8.0，更优选1.5～7.0；要求|ΔMR A-ΔMR B|≥0.1，优选0.5～9.0，更优选1.0～5.0。
在炎热的夏季，室外温度高、湿度大；而室内的温度低、湿度小。当人从室内进入室外时，即从低温低湿环境到高温高湿环境时，人体出汗量增加，这时合适的吸湿率差（ΔMR）可以让面料将皮肤周围空气中的水分吸收走，减少闷热和不适感。另外，外界高温使得水分蒸发，一部分汽化热被带走，衣服和人体之间的微气候环境中的温湿度得以保持在较低的范围内，人体感到凉爽。
在寒冷的冬季，室外温度低、湿度低；而室内的温度高、湿度大。当人从室内进入室外时，即从舒适的高温高湿环境到低温低湿环境时，人体内的水分或汗液较少，具有合适的吸湿率差（ΔMR）的纤维吸收微气候环境中的湿气，运动中的水分子被纤维大分子吸附，水分子会将动能转化成热能而释放，即放出热量，从而保持或调节衣服和人体间的微循环环境，使得温度保持甚至上升，实现保温或升温的目的。   
本发明的双面构造没有特别限定，可以是单面组织的双层构造，如单面涤盖棉（或棉盖涤）组织等；也可以是单面组织的多层构造，如全部线圈添纱组织、部分线圈添纱组织等。可以是双面组织的双层构造，如双面罗纹、双面棉毛、双面变化组织等；也可以是双面组织的多层构造，如双面空气层组织（三明治组织或五明治组织）等。如果是双面组织的双层构造时，优选里纱不在表组织中显露的连接方式，比如以集圈的形式进行连接。
未充满系数表征了面料的紧密程度，是指线圈长度(mm)与纱线直径(mm)之间的比值。线圈长度越长，纱线越细，则未充满系数值越大，面料中未被纱线充满的空间越多，面料越是稀松。其中，当未满系数之比a＜0.5或 a＞2.0时，面料两面的紧密程度差异大，即两面风格差异大，面料的品质有下降的趋势，因此，作为优选，本发明中在一个完全组织及用纱循环内，面A与面B的未充满系数之比a满足如下关系式：2.0≥a≥0.5。
本发明中，对于形成面A和面B的纱线的单丝纤度没有特别限定，优选形成面B的纱线的单丝纤度在2.2dtex以下。当面B作为肌面（靠近皮肤的一面）使用时，合适的单丝纤度有利于面B吸收更多的水分；同时，当纱线的单丝纤度在2.2dtex以下时，纱线手感柔软，面B整体更加平滑，更容易获得较大的接触面积，对于炎热的夏季而言，更加有利于热量的释放和瞬间传导。
本发明中，面料由短纤纱和长丝复丝形成时，短纤纱在面A以及面B上的露出率对面料的保温性和接触冷感有较大的影响。短纤纱的纤维原料可以列举的有羊毛、腈纶、棉、莫代尔、天丝、莱赛尔和粘胶等，还可以列举的有远红外纱线。远红外纱线是通过在纱线中添加远红外粒子或通过涂层等方式获得的，比如远红外聚酯、远红外腈纶等。作为优选，本发明中面A上短纤纱的露出率大于50%，且其纤维原料为羊毛、腈纶和粘胶中的一种或多种。其中，羊毛更优选为防缩羊毛。这里的防缩羊毛是指经过防缩处理的羊毛，即通过化学、生物等方法去除鳞片，或树脂填充包覆法以及二者结合的方法去除羊毛纤维表面的鳞片。当羊毛为防缩羊毛时，面料的光泽感和尺寸稳定性更好。腈纶可以是普通腈纶，也可以是超细腈纶，更优选为超细腈纶。这里的超细腈纶是指单丝纤度在1.1dtex以下的腈纶纤维。当腈纶为超细腈纶时，面料更柔软，品质更优，更适合贴肤穿着使用。本发明中面A上短纤纱的露出率更优选70～100%。当短纤纱在两面上的露出率均超过50%时，考虑到调温调湿性，将短纤纱露出率较大的一面作为面A使用，另一面作为面B使用。
本发明中，面A上的纱线的总纤度没有特别限定，优选30～80英支。当纱线的总纤度低于30英支时，纱线较粗，面料风格粗犷，细腻感有下降的趋势；当纱线的总纤度高于80英支时，纱线较细，纱线强力较低，有可能出现断纱的现象，另外，纱线支数增高，成本也有增加的趋势。
面B上长丝复丝的纤维原料可以列举的有聚酰胺、聚酯、粘胶、天丝、莫代尔、莱赛尔、铜氨纤维、真丝等。作为优选，本发明中面B上长丝复丝的露出率大于50%，且其纤维原料为聚酰胺、聚酯和粘胶中的一种或多种。这里的聚酯纤维可以是普通聚酯纤维（PET），也可以是阳离子染料可染聚酯纤维（CDP），还可以是聚对苯二甲酸丙二醇酯纤维（PTT）等等。这些纤维原料的断面形状也没有特别限定，可以是圆形断面，也可以是三角形、十字形、多叶形等异型断面，长丝的形态没有特别的限定，可以是FDY、DTY等，优选为FDY。这些纤维原料中更优选导热系数较高的纤维，比如聚酰胺纤维。当面B上长丝复丝的露出率大于50%时，可以赋予面B良好的接触凉感。本发明中面B上长丝复丝的露出率更优选70～100%。当长丝复丝在两面上的露出率均超过50%时，考虑到调温调湿性，将长丝复丝露出率较大的一面作为面B使用，另一面作为面A使用。
本发明中，面B上的纱线的总纤度也没有特别限定，优选33～165dtex, 更优选55～84dtex。当纱线的总纤度超过165dtex时，纱线较粗，面料风格比较粗犷、厚重，有可能会影响水分的蒸发，调温调湿的效果有下降的趋势；而当纱线的总纤度低于33dtex时，纱线较细，强力偏低，在编织时可能会出现断纱的现象,同时，纱线越细，面料薄透，调温调湿效果有下降的趋势。
本发明的调温调湿效果是指将面料从一个固定的温湿度条件进入另一个温湿度条件后，所产生的与周围环境温度差值的能力。具体测试时模拟的条件为：冬季从室内到室外的环境改变时，室内温湿度为20℃×65%RH，室外温湿度为10℃×30%RH；夏季从室内到室外的环境改变时，室内温湿度为20℃×65%RH，室外温湿度为30℃×90%RH。
本发明中，更优选，在A面上短纤纱露出率大于50%、长丝复丝的露出率小于50%，在B面上短纤纱露出率小于50%、长丝复丝的露出率大于50%，这样的话，能够最大程度保证两面的性能差别化，即面A具有优越的保温性，面B具有优越的接触冷感，差别明显。
作为优选，本发明中面A的clo值为0.65以上，面B的qmax值为0.12以上。
在制造本发明面料的过程中，可以根据需要在后整理时选择吸水剂、柔软剂、抗静电剂等进行加工。其中，吸水剂可以是聚酯类树脂、丙烯酸类树脂等。柔软剂可以是有机硅类树脂等。抗静电剂可以是阳离子型、阴离子型、非离子型、复配型等，如烷基磺酸盐类阴离子型抗静电剂、季铵盐类阳离子型抗静电剂等等。
由本发明的针织面料所制得的服装，穿着场景不限，可以一年四季单面穿着，也可以根据季节变化两面交替穿着。
下面结合实施例及比较例对本发明作进一步说明。
本发明所涉及的各参数的测试方法如下：
（1）短纤纱的露出率
准备平整无褶皱的针织面料，剪取大小约20cm×20cm的试样5块。取其中1块试样，确定一个完全组织及用纱循环，拆解纱线并画出该面料的组织图，根据纱线形态区分出短纤纱和长丝复丝，接着根据如下公式计算出该面上短纤纱的露出率：
z=x d/y×100%
其中，x d：短纤纱形成的成圈组织的线圈个数，
y：该面上所有成圈组织的线圈个数；
按照同样的方法，测量并计算出余下4块试样的同一面上短纤纱露出率，取平均值作为本发明的短纤纱露出率。
（2）长丝复丝的露出率
长丝复丝的露出率=100%-z。
（3）面A的吸湿率差ΔMR A以及面B的吸湿率差ΔMR B 
①样品准备
准备平整无褶皱的针织面料，剪取大小约20cm×20cm的试样5块；
②吸湿率差ΔMR 
选取其中1块，确定一个完全组织及用纱循环，并标记其中一面为面A，另一面为面B（可以举例的是，当短纤纱在一面上露出率大于50%、在另一面上露出率小于50%，则短纤纱露出率大于50%的一面作为面A，另一面为面B；当短纤纱在两面上的露出率均超过50%时，则短纤纱露出率较大的一面为面A，另一面为面B；当长丝复丝在两面上的露出率均超过50%时，则长丝复丝露出率较大的一面为面B，另一面为面A）；
A、当试样中不存在同时出现在面A和面B的纱线时
a1）分别拆下至少一个完全组织及用纱循环内所有的纱线，并做好标记，将面A的纱线标记为a，将面B的纱线标记为b；
a2）将标记为a的纱线称重（保证纱线重量在1g以上），放入恒温恒湿机中，按60℃×30分钟的条件进行预烘干；
a3）将预烘干后的纱线放入条件为20℃×65%RH恒温恒湿机，进行调湿平衡24小时，称重并记录为W1；
a4）将步骤a3）的纱线放入条件为30℃×90%RH恒温恒湿机，进行调湿平衡24小时，称重并记录为W2；
a5）将步骤a4）的纱线放入条件为105℃的恒温干燥箱，绝干2小时取出，放在干燥器皿内，并在20℃的环境中冷却30分钟，称重并记录为W3；
a6）然后根据以下公式，计算得到面A的ΔMR（%），
ΔMR=MR 2-MR 1 
MR 1=（W1-W3）/W3×100% 
MR 2=（W2-W3）/W3×100% 
其中，
W1：在20℃×65%RH条件下调湿平衡后试验片（除称量瓶重量）的质量（g）
W2：在30℃×90%RH条件下调湿平衡后试验片（除称量瓶重量）的质量（g）
W3：在绝干状态试验片（除称量瓶重量）的质量（g）；
a7）按照步骤a2）～a6），测量并计算出余下4块试样中标记为a的纱线的吸湿率差，取平均值作为本发明面A的吸湿率差ΔMR A；
a8）按照同样的方法，测量并计算出面B的吸湿率差ΔMR B。
B、当试样中存在同时出现在面A和面B的纱线时
将同时出现在面A和面B上的纱线定义为纱线ab，
b1）计算出纱线ab在面A上露出的比例z a
纱线ab在面A上所占比例z a可根据如下公式算得：
z a=x/y×100%
其中，x：在面A上由纱线ab形成的成圈组织的线圈个数，
y：在面A上一个完全组织及用纱循环中成圈组织的线圈总个数；
b2）按b1）的方法，计算出纱线ab在面B上露出的比例z b；
b3）将样布裁剪成5cm×5cm（若样品一个完全组织及用纱循环大于5cm，则必须保证一个完整循环），拆下所有纱线，并做好标记。将面A的纱线标记为a，面B的纱线标记为b，同时出现在面A和面B上的纱线标记为纱线ab；
b4）将标记为a的纱线、标记为b的纱线以及标记为ab的纱线按照步骤a2）～a7）进行测试，将测试结果分别记为ΔMR a、ΔMR b、ΔMR ab；
b5）根据如下公式分别计算出计算面A、面B的吸湿率差ΔMR A、ΔMR B，其中，
ΔMR A=ΔMR a×（1-z a）+（ΔMR ab×z a）
ΔMR B=ΔMR b×（1-z b）+（ΔMR ab×z b）。
（4）调温调湿效果
①取5cm×5cm的试样5块。将试样全部放入干燥箱内预干燥：50℃×1小时，然后放到温湿度为20℃×65%RH的环境内，平衡24小时以上，接着放入10℃×30%RH环境，用温湿度传感器立即记录所有试样的温湿度变化，取平均值作为冬季调温调湿效果的数据；
