(2)、3N水刺无纺布的防水层加工工艺步骤：所述防水层即为改性聚乙烯醇原料
S1、将纤维素纳米晶、羧甲基纤维素、聚乙烯醇加入反应釜中，于120℃搅拌反应0.8-1h，冷却至80-85℃。
S2、加入新癸酸缩水甘油脂，继续搅拌反应0.4-0.6h，加入氨乙基哌嗪和三乙醇胺，充分混合均匀，制得改性聚乙烯醇。
(3)3N水刺无纺布的压纹加工工艺步骤：
S1、花辊的表面刻制凹形花纹；
S2、将花辊过发泡浆；
S3、刮去凹形花纹以外的花辊表面的多余发泡浆；
S4、通过压辊将花辊上凹形花纹中的发泡浆转移至无纺基布上；
S5、将无纺基布上的发泡浆烘至半干；
S6、将无纺布经轧辊热压发泡，所述轧辊由下辊和上辊组成，所述下辊为橡胶辊，上辊为钢辊。
