附图说明
图1为本发明空气雾化吸水毡的结构剖视图；
图2为本发明亲水无纺布层的结构剖视图。
具体实施方式
下面详细描述本发明的实施方式，所述实施方式的示例在附图中示出。 下面通过参考附图描述的实施方式是示例性的，仅用于解释本发明，而不 能解释为对本发明的限制。
如图1所示的一种空气雾化吸水毡，从上至下依次包括表层1、吸水 树脂层2、吸水纤维层3、亲水无纺布层4和底层5，所述吸水树脂层2通 过胶体粘接在所述表层1的下方，所述吸水纤维层3通过胶体粘接在所述 吸水树脂层2的下方，所述亲水无纺布层4通过胶体粘接在所述吸水纤维 层3的下方，所述吸水纤维层3由聚丙烯纤维31和超吸水纤维32交替排列制备而成。
作为上述实施例的进一步优化：
本实施例中优选地，所述吸水树脂层2包括吸水树脂小球和棉布。所 述棉布有两层且四周相互缝合，所述两层棉布之间设置多条相互平行的缝 合线使两层棉布之间形成多条相互平行的通道，所述吸水树脂小球大量分 布在所述通道内。吸水树脂小球通过放入通道内而形成吸水树脂层，这样 当吸水树脂失效后可以拆开并更换吸水树脂有效提高材料的寿命，同时使 吸水树脂小球均匀分布。
本实施例中优选地，所述表层1的面密度为100-150克每平方米，吸 水树脂层2的面密度为30-50克每平方米，吸水纤维层3的面密度为40-60 克每平方米，亲水无纺布层4的面密度为20-30克每平方米，底层5的面 密度为100-150克每平方米。
本实施例中优选地，所述表层1、吸水树脂层2、吸水纤维层3、亲水 无纺布层4和底层5相互之间通过非水溶性的高分子胶体进行粘接。
本实施例中优选地，所述表层1上表面以及底层5下表面涂覆有聚四 氟乙烯涂层。
上述一种空气雾化吸水毡的制备工艺，包括如下步骤：
(1)原料选取，采用吸水纤维，亲水无纺织布为原料；
(2)将上述原料按一定比例进行称重；
(3)切断：将上述原料纤维切断；
开松好的纤网的均匀度较差，最终致使高端车内饰阻燃材料的力学性 能不稳定；若针刺工艺配置不好，则会造成针刺针损伤纤维，最终使制备 出的高端车内饰阻燃材料在特定的工艺下，拉伸和耐磨性能达不到最大值， 甚至会出现大幅度下降的可能。可见纤维之间的开松、混合、梳理和针刺 工艺对最终产品性能的影响很大，工艺之间的合理配置是高端车内饰材料 优良性能的必要条件。
(4)开松：将上述原料纤维分别经过开包机进行纤维的初步开包，然 后输送至预开松机，然后输送至混棉机，最后输送至主开松机。
首先原料要经过YYKB-110开包机进行纤维的初步开包，并经角钉帘输 送YYKS-150型预开松机，其中为了防止输送纤维时掉毛和产生静电而缠 绕，喂入得平帘采用皮帘输入，同时角钉帘表面包覆丁腈橡胶防静电专用 皮帘，这样把原料和木帘棒隔开，防止纤维和木帘棒的缠绕；然后，原料经 过预开松机输送到YYHM-220型大仓混棉机，4种原料在仓里进行进一步的 混合，而后进入YYKS-150型主开松机。纤维开松根据纤维的细度、类型、性能等选用分步开松，先将腈纶纤维和锦纶纤维开松混合，再与碳纤维、 预氧丝开松混合。开松后再经混合，可以将不同等级、不同品种的纤维混 合均匀。分步法的开松混合更加细致，混合的均匀性更佳。
(5)成网：成网梳理工序采用单锡林、双道夫罗拉式梳理机进行，然 后采用交叉式铺网机进行均匀铺网；
经过开松与混合之后，纤维原料进入梳理工序，梳理工序是纤维成网 的关键工序，纤维的梳理工序采用YYSL-185型单锡林、双道夫罗拉式梳 理机进行，本设备适用于1.5D-20Dx25mm-76m的化学纤维梳理成网，单 锡林高速梳理，双道夫出棉多、降低了电能、产量高。YYSL-185型梳理 机的4根090mm罗拉，包缠金属针布，分上、下两组配对，其中第一对上 罗拉轴承座及传动齿轮为尼龙件具有金属检测功能，并有倒车和自停报警 功能；锡林直径中为1230mm,两道夫直径中为492mm,工作辊直径φ为155mm,剥毛辊直径φ为122mm,刺辊直径φ为295mm。原料经过锡林、 工作辊、剥取辊的分梳和剥取作用之后，初始的原料成单根纤维薄网状态， 其面密度一般在25g/m2左右，针刺工序中需要的纤维网一般需要进一步的 铺网来增加厚度和平方米克重。
采用YYPW-300型交叉式铺网机，该铺网机铺网往复分六断速精准控 制，将纤网不匀率控制到最低。根据250g/m2克重及纤维网均匀要求确定 铺网层数为10层。
(6)针刺成毡：预刺刺针和主刺刺针采用Y型针，预刺向下刺的针 刺深度为9-11mm，向下刺的主针刺深度为7-9mm，针刺成毡即可。
针刺工艺参数的不同，对制备出来的非织造材料性能有很大的影响。 本课题首先对影响产品性能的主要针刺工艺参数进行分析，根据不同的原 料性能指标和产品的性能要求，合理设置针刺工艺参数，以制得性能更优 的产品。
针刺加固是一种典型的机械加固方法，针刺加固的基本原理:用截面为 三角形或其他形状且其棱上带有钩齿的金属针，对蓬松的纤网进行反复穿 刺。当数以万计的刺针刺入纤网时，刺针棱上的齿钧就会钩住纤网上下表 层和里层的纤维，随着刺针的刺入运动，被刺针的棱钩住的纤维发生了位 移的变化，即钩住的纤维在纤维网截面内进行穿插运动，使纤维在运动的 过程中相互交织和缠结在一起。由于刺针对纤网摩擦力的作用和纤网中纤 维上下位移变动对纤网产生了一定的挤压，使得因压缩而变薄。刺针刺入 纤网一定深度后回升，此时的刺针是做顺向运动，刺针沟槽中的纤维脱离 刺针近似垂直状态滞留在纤网之中，就像销钉一样钉入纤网，使已经压缩 的纤维不再回复原状，这样刺针往复的运动就使纤网制成了又一定厚度和 强度的复合材料。
①刺针：刺针是针刺机中最为重要的一个机件，其规格和质量直接影 响无纺布的外观和质量，因此对刺针的形状、规格、选材和制造精度的选 择尤为重要。本发明预刺刺针和主刺刺针的刚度均为HV635，此剌针的加 工经过渗氦处理，机械性能强韧、耐磨、使用寿命长。采用Y型针，该针 切入角呈弧形，能避免损伤纤维，同时齿钩带的纤维量均匀。由于切入槽 不深，刺针不易断，则织物结构和外观质量和拉伸强度较均匀。预刺刺针 规格15x18x36x3R28-333YP3.2,主刺刺针规格15x28x36x3M24-222Y.P3.2。 从预刺刺针和主刺刺针的规格中可以看出，预刺刺针钩刺针体单棱上有三 个齿钩，而主刺刺针的钩刺针体的单棱有两个齿钩。
②针刺深度:针刺深度指刺针针尖到托网板上表面之间的距离，即刺针 穿过纤网后伸出网外的长度。当选用的刺针一定后，刺针深度大时，针刺 带动的纤维大，纤维间的穿插缠结效果充分。但是针刺深度要适当，深度 过分大了会使纤维的损伤较大，造成纤维的断裂较多，使得织物的强度降 低，同时也会使针折断较多。制备内饰阻燃材料的平方米克重为250g/m2， 结合上述分析预刺向下刺得针刺深度设定在9-11mm,向下刺得主刺针刺深度设定7-9mm范围内，同时向上刺得针刺深度分别降低4mm.
③针刺密度:针刺密度指单位面积维网内所受到的刺针数。针刺密度 大，织物的强力也会提高，若针刺密度过大，则会造成断针，从而影响产 品质量.课题选取预刺机植针密度4000针/m2,输出速度1.35m/min,针刺频 率346针/min；主刺机植针密度7000针/m2,输出速度1.35m/min,针刺频 率666针/min。则预刺机针刺密度为102.5针/cm2,主刺机针刺密度为345.3 针/cm2。
