Description

一种超细纤维面料及其制造工艺
技术领域
本发明涉及一种超细纤维面料及其制造工艺，属于高档纺织面料技术领域。
背景技术
超纤是超细纤维PU合成革的简称，海岛型超细纤维是超细纤维的一个种类，分海岛长丝和海岛短纤(包括定岛型和不定岛型)两大类。海岛长丝一般通过机织和针织生产麂皮绒面料，用于服装、服饰的制作；海岛短纤通常通过针刺非织造生产厚型仿皮面料，主要用于制鞋、沙发、汽车内饰、服饰等。所有超纤面料一般都以实现高仿真皮为最高目的，定岛型超面料采用碱减量开纤，相对于不定岛型超纤面料采用甲苯开纤比较安全和环保。
普通的超细纤维针刺无纺布，通常做法是使超细短纤经过开包、混仓、梳理、铺网、针刺等工序，其设备投资昂贵，生产工艺条件高，能耗大，产量低，面料的平均厚度、克重控制难度高，给后续树脂含浸、染色深加工带来难度，生产的面料的厚度规格局限性较大，一般只能生产0.5-2.0mm中等厚度且无弹性规格坯布，不能直接生产0.5mm以下厚度且有弹型规格的坯布。也有厂家为追求0.5mm以下规格坯布，采用先生产1.2mm以上厚度，再采用面料横向厚度剖切片皮工艺，但这种做法的缺陷是：原先缠结一起的纤维被切开后，导致面料强度下降明显，影响后续应用。
有鉴于此，本申请人对此进行专门研究，开发出一种超细纤维面料及其制造工艺，本案由此产生。
发明内容
为了解决现有技术中存在的上述缺陷，本发明的目的是提供一种强度高、厚度薄的超细纤维面料及其制造工艺，为了实现上述目的，本发明采取的技术方案如下：
本发明为填补0.5mm以下超纤面料的规格，采用超细纤维长丝，通过针织，拉毛，刺毛工艺，生产出厚度在0.5mm以下且有弹性的坯布，再经树脂含浸、开纤、染色、磨毛等后整理，可应用到汽车内饰、服饰等领域。
一种超细纤维面料，包括基体部分和表面部分，所述基体部分由定岛型海岛长丝或/和普通长丝构成，所述表面部分由短纤维构成，所述面料为基体部分和表面部分相互络合的无纺结构。
作为优选，所述基体部分还包括涤纶高强丝，纤度为75-100D。
作为优选，所述定岛型海岛长丝为聚酯海岛长丝或/和锦纶海岛长丝，纤度为75-150D，所述普通长丝为聚酯长丝或/和锦纶长丝，纤度为50D-200D，所述短纤维为聚酯海岛短纤或/和锦纶海岛短纤。
所述超细纤维面料的成品厚度在0.5mm以下。
一种超细纤维面料的制造工艺，基体部分的定岛型海岛长丝或/和普通长丝通过纬编、经编或梭织工艺，然后通过拉毛处理在其表面形成拉毛层，在拉毛层上铺短纤维，并利用无纺络合技术使短纤维和基体表面的拉毛层形成络合的无纺结构，再经含浸、干燥、开纤、染色以及后处理得到超细纤维面料，具体包括如下步骤：
(1)以定岛型海岛长丝或/和普通长丝为主要原料，并加入75-100D涤纶高强丝，毛圈机针织，通过纬编工艺织成坯布；(2)将坯布进行拉毛；(3)铺网；(4)针刺；(5)机缸预缩；(6)第一次烘干和第一次定型；(7)含浸；(8)碱减量开纤；(9)第二次烘干和第二次定型；(10)第一次磨毛；(11)染色；(12)第三次烘干和第三次定型；(13)第二次磨毛；(14)第四次烘干和第四次定型；(15)检验、打卷、入库。
所述步骤(1)中，控制线圈高度在0.2-0.3cm之间，坯布重量克重200-300g/m2，门幅为170-200cm。
所述步骤(2)中，所述坯布经拉毛机拉毛4次，能将毛彻底拉出来，使绒毛长度在0.5-2.5cm。
所述步骤(3)中，经成网机在拉毛后的制品上均匀铺上一至三层无纺针刺纤维(即短纤)，每层克重为10-20g，铺网机出网的速度为0.3-0.5m/min。
所述步骤(4)中，经针刺机针刺4次以上，经无纺针刺纤维缠结得到复合基布，无纺时的针刺压力参数为6公斤，针刺机的频率控制在500-900刺/min，针板布针密度为7500针/米2，生产出厚度在0.45-1.0mm、克重为250-350g/m2，门幅为170-200cm的复合基布。
所述步骤(5)中，将复合基布进行机缸预缩，预缩时温度为130℃-180℃，所用时间为30-60min，预缩可进一步提高面料密度，减少水性聚氨酯的使用量，提高回弹性，改善手感。
所述步骤(6)第一次烘干和第一次定型：将复合基布放到定型机机芯烘干切边控制门幅，烘干温度在110-130℃，烘干时根据坯布密度，调节温度和车速，以坯布里外烘干烘透为合适。
所述步骤(7)树脂含浸：在树脂与水性聚氨酯的混合液中对复合基布分别进行含浸处理，包括第一次含浸和第二次含浸，所述第一次含浸：浸液浓度在10％-17％的水性树脂，车速5-7m/min，以带液量120％-130％，调节压力辊压力为0.5MPa，使复合基布的水性树脂的增重量为10％±2％；所述第二次含浸：浸液浓度在12％-20％的水性聚氨酯，车速7-8m/min，以带液量120％-130％调节压力辊压力为0.5MPa，使复合基布的水性聚氨酯的增重量为8％±2％。
所述步骤(8)碱减量开纤：碱液浓度为5％，升温为5℃/min，高温区温度为96-110℃，所用时间为45-60min，开纤率18％-35％；进行中和处理时，采用柠檬酸进行，并将pH值调节到6-7，出缸后采用连续化逆流式水洗。
所述步骤(9)第二次烘干和第二次定型：含浸和碱减量开纤后进行烘干和定型，以便于磨毛。
所述步骤(10)第一次磨毛，因开纤后复合基布表面凹凸不平，经磨毛后可使复合基布均匀着色。
所述步骤(11)染色：复合基布缝头后，进缸染色、还原清洗、脱水、定型，初染色时将分散染料的始染温度控制在室温～60℃，1h后逐渐升温至130℃，保温1～2h，然后充分水洗，染深色时进行还原清洗。
分散染料由高温匀染剂、扩散剂和重量百分比浓度为98％的醋酸配置而成，按照每升染料计算，所述高温匀染剂用量为0.2～1.2g/L，扩散剂用量为0.5～1g/L，醋酸用量为0.5～1.5g/L。还原清洗时，按照每升染料计算，烧碱用量为6ml/L，保险粉用量为2.5g/L，分散剂用量为0.1～0.5g/L。
所述步骤(12)第三次烘干和第三次定型：还原清洗后再次进行烘干、定型，定型时控制上述基布温度为100℃-170℃，车速调至5-30米/分，车速为30-60米/分；
所述步骤(13)第二次磨毛：常规产品使布面绒毛长短一致无绒疵为合格，如客户对布面有“书写效果”需求，可以通过保留绒毛的长度以实现。
所述步骤(14)第四次烘干和第四次定型：最后根据产品需求进行定型；
所述步骤(15)检验、打卷、入库。
本发明能实现如下技术效果：
(1)本发明填补了针刺无纺布的正常生产(非增加机械片皮工序)厚度规格空白，能生产出厚度为0.5mm以下的成品；
(2)本发明生产出的面料由于在铺网时，可以选择与坯布不同性质纤维，如针织时采用涤纶长丝纤维(是涤纶高强丝还是锦纶长丝，请确认)，铺网时采用锦纶短纤，使铺网纤维和坯布纤维充分缠结，又由于在染色时可以只投分散染料，分散染料对锦纶短纤不上色，在面料表面就形成了白色加任意色的双色效果，也丰富了面料的表观颜色，因此本发明工艺可以实现成品面料的双色效果，采用上述留白染色的工艺使其具有非常好的双色效果，高档美观；
(3)采用75-100D涤纶高强丝和75-250D定岛型海岛长丝和10D锦纶短纤，并采用上述技术方案，使面料物性指标明显高于同厚度的针刺无纺布；
(4)因本发明的面料坯布组织有较好的回弹性，加入常规的水性树脂及水性聚氨酯50％的用量，既有皮感，同时可现实10-30％的弹性伸长率，比普通化纤面料更具仿真性，比天然皮革更具回弹性，从而扩大了面料的应用范围，可应用于对弹性伸长性需求的汽车内饰、女士春秋时装等高端面料领域，提高产品市场竞争力；
(5)本发明工艺生产的面料，保留了针织面料的悬垂性，通过针刺加入超细短纤后，增加了它的透湿度，可满足服饰领域的多种需求；还有通过针刺铺网加密，面料的隔音性有较大的提高，可增强汽车及家居内包的装饰材料的隔音功能；
(6)本发明生产工艺相比传统同规格的针刺无布，设备投入节约3/5，产能提高2倍且能耗基本持平，原料成本下降1/5，CV值控制简易，能实现高质高效量产，且所用原料合工艺均符合环保要求。
