Because the fibers are not tightly bonded, the fibers are easily broken and entangled with each other, so that the core products form agglomerates and the thickness is uneven.

Description

一种耐水洗枕芯的填充物的制备方法及其工业水洗工艺 技术领域
本发明属于枕芯制造领域，具体涉及一种耐水洗枕芯的填充物的制备方法及其工业水洗工艺。
背景技术
随着人们生活水平的提高，人们对出行时的睡眠质量也逐步有了更高的要求，由于酒店有着人员流动大，成分不稳定的特点，酒店用纺织品每天都会被不同的人使用，如果不及时清洗，填充物中藏匿的各种物质容易透过被褥套、枕套造成客人的交叉感染。目前，枕芯填充材料按形态分包括球状纤维(珍珠棉)、片状棉和梳理棉，其中球状纤维(珍珠棉)和絮片状棉均可水洗，而梳理棉却难以水洗。
球状纤维：三维立体卷曲涤纶纤维棉，通过特殊成球技术加工成球形状棉。珍珠棉球内部空心，有较大的透气空间，保暖性和透气性更强，而且珍珠棉球涤纶纤维内有孔，弹性好，其产品经绗缝后，会自动膨胀，不易结块，即使机洗也不会变形，多用于枕头的填充材料。但是这类芯类产品表面凹凸不平，必须使用厚密材料包裹其外，且成本较高。
絮片状棉：絮片是经过混合→开纤→梳理→铺网→干燥定型工艺加工而成。当前，国内多采用热粘合的生产方法，它必须选用两种或两种以上的纤维混合，其中有一种纤维作为粘合纤维即热熔纤维，它的熔点比其它混合纤维的熔点低，当纤维梳理成网进入干燥机以后，干燥温度高于热熔纤维的熔点，***熔化，然后与其它高熔点纤维粘合在一起，形成絮片。絮片状棉可水洗、均匀且平整，但絮片状填充料的密度高、用量多加工成本高且蓬松度不够。
梳理棉：梳理式棉是经过开松→混棉→梳理→铺网→装套工艺加工而成。梳理棉填充材料产品水洗时纤维容易软化变形，由于纤维之间结合不紧密，纤维间容易断裂，相互缠绕，从而芯类产品形成结块，厚薄不均匀。但梳理棉填充材料产品蓬松、柔软，市场占比大，填充用量小且加工成本相对比较便宜。
专利号：201410087049.5，专利名称为：一种多组分纤维混配织物的生产工艺的专利中，将再生纤维素纤维与超细涤纶纤维混配呈∞连体螺旋卷曲型混合纤维，在织造过程中，毛倍比比一般全棉产品高，不会产生毛圈过度倒伏，影响面料外观丰满程度的现象，使用寿命长，纤维蓬松度及柔软度好。
