Interval type hydrophilic nonwoven material and preparation method thereof

Abstract

The invention discloses an interval type hydrophilic nonwoven material and a preparation method thereof. The nonwoven material basement is arranged in an interval way and processed through hydrophilic treatment form hydrophilic areas which are arranged at intervals. The preparation method of the interval type hydrophilic nonwoven material can be used to perform various on-line functional treatments to the nonwoven material, the equipment modification is easy, the investment is low, the preparation method can not conflict with the production technology of the common nonwoven material, the existing equipment and process can also be used; and therefore, the method is easy to realize and the production cost is low. The interval type hydrophilic nonwoven material can have different functions; the interval type hydrophilic nonwoven material can be freely cut into multiple pieces with small breadth along the transverse breadth direction, and for example the nonwoven material with small breadth in the arrangement manner of 'non-treatment + hydrophilic treatment + non-treatment' can be prepared; and the amount of raw material used in hydrophilic treatment can be reduced, the cost is saved, and the bad effects of some raw materials to human body can be lowered.

Description

【Technical field】 [0001] The invention relates to the field of nonwoven materials, in particular to a hydrophilic nonwoven material and a manufacturing method thereof. 【Background technique】 [0002] Non-woven materials have been greatly developed in recent years, and their application fields are becoming more and more extensive, especially in medical and health fields such as disposable sanitary napkins, diapers, disposable wet wipes, disposable protective clothing, surgical gowns, and masks. , but with the promotion of applications, according to different needs, the requirements for the hydrophilic function, antibacterial and skin care functions of nonwoven materials are getting higher and higher, and there are more and more; but following, Its cost is also increasing, hindering the application of functional nonwoven materials. [0003] In the application of non-woven materials in diapers and sanitary napkins, in order to prevent urine and menstrual blood from leaking alo...

AI Technical Summary

Problems solved by technology

[0003] In the application of non-woven materials in diapers and sanitary napkins, in order to prevent urine and menstrual blood from leaking along the edges of diapers and sanitary napkins, some people have developed a variety of anti-side leakage diapers and sanitary napkins. Diversion grooves are provided on the surface of diapers and sanitary napkins, and there are structures such as raised guards on both sides of diapers and sanitary napkins. However, these anti-side leakage structures have their disadvantages, such as raised guards. When the body is in close contact with the sanitary napkin due to sports or other circumstances, the raised guard will be pressed against the surface of the diaper and sanitary napkin, losing the anti-side leakage function

Someone invented the use of spunbonded non-woven fabrics for the surface layer of diapers and sanitary napkins. The surface layer is generally a non-woven material that has undergone hydrophilic treatment, and SMS non-woven fabrics are used for the leak-proof partitions on both sides, which are bonded with glue. , but the bonding of this kind of spunbond nonwoven fabric and SMS nonwoven fabric will cause many problems, such as peeling, glue bleeding, etc., and the process is complicated and the cost is high
