Abstract

The invention relates to a production method of SMS (Spunbond Meltblown Spunbond) non-woven fabric capable of alcohol and water resistance on a front side and water loving on a back side. The production method is characterized that the front side of the non-woven fabric is spunbond non-woven fabric, and 10-15% of water-resistant master batches for spunbond are added into the raw material of the front side; two layers of meltblown non-woven fabric is sandwiched at the middle, and 10-15% of water-resistant master batches for meltblown are added into the raw material of the meltblown non-woven fabric; the back side is spunbond non-woven fabric, and 4-8% of water-loving master batches for spunbond are added into the raw material of the back side; the non-woven fabric is obtained through drying after forming by a hot rolling method. The non-woven fabric obtained according to the method is soft in handfeel, and a bonding point of two materials cannot be layered and separated when suffering water and heat.

Description

technical field [0001] The present invention relates to a method for SMS nonwovens. It belongs to the technical field of non-woven fabric production. Background technique [0002] Before the present invention was made, the same material only had the function of repelling alcohol and water, or only had the function of hydrophilicity. [0003] To realize the integration of the two functions, the two materials are generally bonded together by hot-melt adhesive. It mainly has the following deficiencies: [0004] 1. ------ Bonding between two materials, the bonding area is large, and the hand feeling is hard; [0005] 2. ------ Delamination and delamination between the bonding points of the two materials when heated (it is easy to delaminate if it is greater than 50°C); [0006] 3. ------ The bonding point between the two materials will detach from the water layer. Contents of the invention [0007] The object of the present invention is to overcome the above-mentioned dis...
