Problems solved by technology

[0003] In the prior art, it is widely accepted that antibacterial nonwoven materials are prepared by post-finishing methods, that is, all kinds of antibacterial materials, water-based resins, fillers, etc. There are many types of antibacterial materials suitable for post-processing and post-finishing methods. The antibacterial finishing process is flexible and cost-effective, but the antibacterial durability of the product obtained by this treatment method is poor, and it is not resistant to washing and friction, and the prepared antibacterial nonwovens feel bad

Abstract

The invention discloses a melt-blown composite nano-antibacterial super-soft non-woven material and a preparation method thereof. The melt-blown composite nano-antibacterial super-soft non-woven material comprises a first flexible met-blown layer, a first nano fiber antibacterial layer, a nano fiber hydrophilic layer, a second nano fiber antibacterial layer and a second flexible melt-blown layer, all of which are sequentially arranged from top to bottom. The first nano fiber antibacterial layer and the second nano fiber antibacterial layer are both formed by alternately laminating nanometer titania material layers and nano fiber antibacterial material layers. The melt-blown composite nano-antibacterial super-soft non-woven material achieves good softness, good hand feeling and high comfort through the first flexible met-blown layer and the second flexible met-blown layer. The nano fiber antibacterial material layers and the nanometer titania material layers are alternately laminated to form a continuous antibacterial body, so that the non-woven material has a lasting antibacterial effect. The nanometer titania layers have a good ultraviolet-proof function. Then non-woven material has a good hydrophilic property through the nano fiber hydrophilic layer.

Description

technical field [0001] The invention belongs to the field of nonwoven materials, and in particular relates to a melt-blown composite nano antibacterial supersoft nonwoven material and a preparation method thereof. Background technique [0002] Nonwovens are also known as nonwovens, nonwovens, nonwovens, nonwovens or nonwovens. Nonwoven technology is a material processing technology that originates from textiles but surpasses textiles. Whether in many fields such as aerospace technology, environmental protection, agricultural technology, medical care or people's daily life, non-woven new materials have become an increasingly important product. While gradually accepting the quality and performance of nonwoven materials, various application fields have also put forward more functional requirements. Today, as health and environmental protection are increasingly valued, elements such as antibacterial and antibacterial are gradually integrated into people's lives. [0003] In th...
