Problems solved by technology

However, the fixation of the acid powder on the absorbent layer is unstable and unevenly distributed, which will affect the function of the weak acid barrier and reduce the comfort of consumers
[0004] By adding weakly acidic substances to the liquid of wet wipes or facial masks, a weak acid barrier will also be formed on the surface of the non-woven fabric, which will play an antibacterial and protective role during use. However, the use of wet wipes or facial masks has limitations and practical effects. Can not play a long-term protective role, the scope of application is also limited

Abstract

The invention provides a functional non-woven fabric. The functional non-woven fabric is prepared from weakly acidic and weakly hydrophilic functional fibers or is prepared by carding the weakly acidic and weakly hydrophilic functional fibers into meshes and then gluing the meshes by hot air. While an infiltration function of the non-woven fabric is ensured, the reverse osmosis is reduced, meanwhile, the antibacterial performance is good, and the functional non-woven fabric is comfortable to use. The invention simultaneously provides a preparation method of the functional non-woven fabric, weakly acidic oil and / or weakly hydrophilic oil is added in fiber treatment oil before spinning to change the performance of the fibers, thus, functions of the non-woven fabric are uniform, storage and transportation are facilitated, and the performance maintaining time is long. The functional non-woven fabric is low in cost, the method is simple, application is facilitated, and finished products canbe widely applied to multiple fields such as cleaning and medical treatment.

Description

technical field [0001] The invention relates to the field of nonwoven fabrics, in particular to a functional nonwoven fabric with weak acidity and weak hydrophilicity and a preparation method thereof. Background technique [0002] Non-woven fabric is a kind of fabric formed without spinning and weaving. It is just oriented or randomly arranged textile short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. It directly uses polymer chips, short fibers or filaments to form new fiber products with soft, breathable and planar structure through various web forming methods and consolidation technologies. [0003] The patent with the publication number CN202761544U discloses a weak acid dust-free composite sanitary napkin, including a main body and wings. Wherein, the main body includes a permeable layer, an absorbing layer and an isolating layer, and the absorbing layer is fixed between the permeating layer a...
