Embodiment 1-6

[0040] As described in Table 1, the main difference between Examples 1-6 is that the raw material ratios of the antibacterial particles are different.

[0041] Example 1 is taken as an example for description below. The embodiment of the present application discloses an antibacterial non-woven fabric, which is composed of an antibacterial spunbond mesh and a cotton fiber mesh. PP 60Kg and antibacterial agent 10kg are prepared as raw materials.

[0042]The present embodiment also discloses a preparation method of an antibacterial non-woven fabric, and the specific method is as follows:

[0043] S10, Preparation of Inorganic / Organic Hybrid Composite Nanoparticles:

[0044] S101, dissolve 1kg of chitosan in 5L of distilled water to form a suspension, and place it in a ball mill, select agate balls with a diameter of 0.5cm to pulverize the chitosan in the suspension, at a rotational speed of 500r / min , the time is 2h; the obtained product is added to the ultrasonic crusher, and...

Embodiment 7

[0054] The difference between this example and Example 1 is that dodecylamine in step S102 is replaced with tetradecylamine.

Embodiment 8

[0056] The difference between this example and Example 1 is that dodecylamine in step S102 is replaced with hexadecylamine.

Abstract

The invention relates to the technical field of non-woven fabrics, and particularly discloses an antibacterial non-woven fabric and a preparation method thereof. The antibacterial non-woven fabric is formed by compounding an antibacterial spunbond net and a cotton fiber net, and the antibacterial fiber net is prepared from antibacterial particles and fiber resin by adopting a spunbond process; the antibacterial particles comprise fiber resin, an antibacterial agent and a plastic additive; the antibacterial agent is prepared from inorganic / organic hybrid composite nanoparticles, polyquaternium, ethylenediamine tetraacetic acid and polyhydric alcohol; the inorganic / organic hybrid composite nanoparticles are compounds formed by micro-nano chitosan, nano-silver and nano-crystal stone powder. The preparation method of the antibacterial non-woven fabric comprises the following steps: mixing the fiber resin, the antibacterial agent and the plastic additive, extruding, cooling and pelletizing to obtain antibacterial particles; mixing the antibacterial particles and fiber resin, and preparing an antibacterial spunbond net by adopting a spunbond process; the antibacterial spunbond net and the cotton fiber net are subjected to composite spunlace treatment and dried, and then the antibacterial non-woven fabric is obtained. The antibacterial non-woven fabric provided by the invention has excellent antibacterial property.

Description

technical field [0001] The present application relates to the technical field of non-woven fabrics, and more particularly, to an antibacterial non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics (also known as non-woven fabrics) have been widely used in various fields due to their short process flow, fast production speed, high output, low cost, wide use, and many sources of raw materials. However, due to people's higher and higher requirements for the quality of life, the requirements for antibacterial and bacteriostasis of antibacterial non-woven fabrics are also higher and higher. At present, domestic antibacterial non-woven fabrics are mainly produced in two ways: dissolving antibacterial agents in fibers to make antibacterial fibers, and directly using antibacterial fibers to make fabrics; post-processing the fabrics formed by fibers with antibacterial agents to obtain antibacterial fibers performance. [0003] At present...
