  • the present invention relates to the technical field of SM materials, and specifically relates to a preparation method of SM materials for sanitary materials.
  • the woven membrane is composited. Although it has high strength and good anti-permeability, it has poor air permeability, moisture permeability and softness.
  • SM non-woven fabrics made from melt-blown non-woven fabrics and spun-bonded non-woven fabrics can solve the problem of air permeability. , moisture permeability and softness issues, but SM non-woven fabrics are easy to delaminate, have low strength, and poor permeability resistance.
  • the most commonly used method at present is to increase the thickness of non-woven fabrics.
  • increasing the thickness of non-woven fabrics will also cause the SM non-woven fabrics to The air permeability, moisture permeability and softness are reduced, which will also cause the SM non-woven fabric to have a large thermal shrinkage rate and poor uniformity.
  • thermal shrinkage method there is no way to improve the strength and permeability resistance of SM non-woven fabrics while improving the air permeability, moisture permeability, softness, and uniformity of SM non-woven fabrics, avoiding delamination, and reducing the resistance of SM non-woven fabrics.

技术领域
本发明涉及SM材料技术领域，具体涉及一种卫生材料用SM材料的制备方法。
背景技术
目前，消费者除了关心纸尿裤的安全性外，选择纸尿裤更多考虑其舒适性，而透气性又是影响舒适性的一个重要因素。当婴幼儿睡觉或外出前，父母可能为他们穿上纸尿裤，在他们便溺前的好长一段时间，如果纸尿裤透气性不好，婴幼儿会因为纸尿裤不透气，体表温度升高，觉得不舒服，从而引起皮肤不适。另外，在有便溺情况时，纸尿裤与皮肤之间的空隙就会变得湿热，若透水蒸气性好，会减轻湿热的程度，增强舒适度；反之，透水蒸气性太差，产生的焐热感会使婴幼儿不舒服，严重时还会引起湿疹；随着中国三胎政策的放开，纸尿裤的市场需求量会越来越大；现有的纸尿裤材料主要是将聚乙烯膜与纺粘无纺布膜进行复合，虽然强度高，抗渗透性好，但是透气性、透湿性和柔软度差，使用熔喷无纺布与纺粘无纺布复合制得SM无纺布，能够解决透气性、透湿性和柔软度的问题，但是SM无纺布易分层，而且强度低，抗渗透性差。
为了提高SM无纺布的强度和抗渗透性，解决易分层的问题，目前最常用的方法是增加无纺布的厚度，但是增加无纺布的厚度的同时，会造成SM无纺布的透气性、透湿性和柔软度降低，还会造成SM无纺布的热收缩率大，均匀性差。目前，还没有能够在提高SM无纺布的强度和抗渗透性性的同时，提高SM无纺布的透气性、透湿性、柔软度、均匀性，避免分层，并降低SM无纺布的热收缩率的方法。
