(5)将步骤(4)处理后的纤维网由斜帘送入铺网机进行铺网，铺网机均匀平铺叠加使其得出所需的平方克重，得到纤维絮片；
(6)将步骤(5)得到纤维絮片经过平帘输送入三角形导毛帘进行预刺针，预刺完进入下刺针机进行底面刺针。
絮片上下面针刺好后进入切断机按照所需尺寸切断后，得到多重纤维混合保暖絮片1。
实施例2：保暖絮片的制备
按重量计，称量60％粘胶纤维、20％细旦涤纶纤维和20％三维卷曲涤纶纤维。其中，粘胶纤维(1.35dtex，3.8mm)，细旦涤纶(1.08dtex，6.1mm)，三维卷曲涤纶(3.60dtex，64mm)。
保暖絮片的制备方法与实施例1相同，制备得到多重纤维混合保暖絮片2。
实施例3：保暖絮片的制备
按重量计，称量70％粘胶纤维、22％细旦涤纶纤维和8％三维卷曲涤纶纤维。其中，粘胶纤维(1.35dtex，3.8mm)，细旦涤纶(1.08dtex，6.1mm)，三维卷曲涤纶(3.60dtex，64mm)。
保暖絮片的制备方法与实施例1相同，制备得到多重纤维混合保暖絮片3。
实施例4：保暖絮片厚度测试
对实施例1～3制备得到的多重纤维混合絮片以及桑蚕丝絮片、羊毛絮片、棉絮片、三维卷曲涤纶絮片进行厚度测试，结果如图1所示。
由图1可知，对于不同纤维原料的保暖絮片，在相同面密度下，絮片厚度并不相同，其中三维卷曲涤纶絮片的厚度最大，多重纤维混合絮片1、2、3的厚度值都较小，与棉絮片接近，桑蚕丝和羊毛絮片的厚度居中。对于同种纤维原料保暖絮片，絮片厚度随着面密度的增加而逐渐增加。
实施例5：保暖絮片蓬松度测试
在不同面密度实验条件下，对实施例1～3制备得到的多重纤维混合絮片以及桑蚕丝絮片、羊毛絮片、棉絮片、三维卷曲涤纶絮片进行蓬松度测试，结果如图2所示。
由图2可知：在相同面密度的实验条件下，多重纤维混合絮片3的蓬松度较低，与棉絮片接近，三维卷曲涤纶的含量增加的多重纤维混合保暖絮片1和 多重纤维混合保暖絮片2的蓬松度得到改善。对于同种纤维原料的保暖絮片，随着絮片面密度增加，絮片的蓬松度呈减小的变化趋势。
实施例6：保暖絮片压缩率和压缩回复率测试
对实施例1～3制备得到的多重纤维混合絮片以及桑蚕丝絮片、羊毛絮片、棉絮片、三维卷曲涤纶絮片进行压缩率和压缩回复率进行测试，结果如表1所示。
表1 絮片压缩率、压缩回复率测试结果
Figure PCTCN2018097190-appb-000001
由表1可知：七种絮片的压缩率都在45％以上，根据GB/T 22796-2009《被、被套》的规定，属于优等品。压缩率是表征絮片蓬松程度的一个重要指标，三维卷曲涤纶絮片的压缩率最好，多重纤维混合絮片1、2的压缩率优于桑蚕丝和棉絮片，多重纤维混合絮片3的压缩率较低。五种絮片的压缩回复率都达到75％以上，同样属于优等品，三维卷曲涤纶絮片的压缩回复率最好，其次是多重纤维混合絮片1、2。絮片压缩回复率的高低，反映了絮片的弹性回复特性，是其产品服用性能的重要指标。絮片具有很好的压缩回弹性，可以提供持久的保暖性能，三维卷曲涤纶的加入，赋予了絮片三维空间结构，增加絮片的弹性和耐疲劳性。
实施例7：保暖絮片透气率测试
在不同面密度实验条件下，对实施例1～3制备得到的多重纤维混合絮片以及桑蚕丝絮片、羊毛絮片、棉絮片、三维卷曲涤纶絮片进行透气率测试，结果如图3所示。
由图3可知：在相同面密度的实验条件下，由于羊毛纤维具有天然卷曲，纤维之间空隙较多，絮片结构蓬松，在一定的压力下气流较容易通过絮片中的空隙，所以透气量大。在三维卷曲涤纶中，其纤维有着持久的自然卷曲和三维空间结构，并且，粘胶纤维具有良好的透气性，有利于人体生理循环，因此， 多重纤维混合絮片1、2、3均获得的较大的透气量。
对于同种原料的保暖絮片，随着面密度的增加，厚度增加，絮片越密实，透气率逐渐下降。
实施例8：保暖絮片透湿率测试
在不同面密度条件下，对实施例1～3制备得到的多重纤维混合絮片以及桑蚕丝絮片、羊毛絮片、棉絮片、三维卷曲涤纶絮片进行透湿率测试，结果如图4所示。
由图4可知：在相同面密度的实验条件下，桑蚕丝絮片的透湿率最好，其次是多重纤维混合絮片3，多重纤维混合絮片1、2的透湿性也相对较好。由于粘胶纤维具有较好的吸湿性能，作为保暖絮片，其吸湿性最符合人体皮肤的生理要求。絮片的透湿性与絮片的密度、纤维自身吸湿、纤维间的空隙等因素有着很大的关系，随着絮片面密度的增大，纤维间的接触点愈多，对通道传递水分子的阻碍愈大。因此，透湿性明显地下降。
实施例9：
絮片的保暖性与纤维集合体的综合热阻相关，热阻越高，则絮片的保暖性能越好；同时与纤维夹层中静止的空气数量有关。在不同面密度实验条件下，对实施例1～3制备得到的多重纤维混合絮片以及桑蚕丝絮片、羊毛絮片、棉絮片、三维卷曲涤纶絮片进行保暖性测试，结果如图5所示。
由图5可知：在相同面密度的实验条件下，桑蚕丝絮片的克罗值最大，其次是多重纤维混合絮片1、2。原因分析：细旦涤纶纤细致密的纤维层能锁定空气，产生稳定的静止空气层，起到保温效果，又考虑到三维卷曲涤纶絮片采用的是三维空间结构，蓬松度较高，絮片静止空气含量较多。随着面密度增加，多重纤维混合絮片的克罗值不断加速增大，当面密度为1100g/m 2时，仅次于蚕丝絮片，故增加多重纤维混合絮片的面密度也可明显提高其保暖性。
对于同种原料保暖絮片，随着面密度的增加，絮片厚度增加，单位时间内散失的热量降低，热阻增大，克罗值不断递增，保暖性越好。
以上所述实施例仅是为充分说明本发明而所举的较佳的实施例，本发明的保护范围不限于此。本技术领域的技术人员在本发明基础上所作的等同替代或变换，均在本发明的保护范围之内。本发明的保护范围以权利要求书为准。
