Problems solved by technology

However, since the composite material non-woven fabric in the above-mentioned technical solution is processed by using a variety of fibers with different components, the requirements for the degree of entanglement between different fibers are relatively high in the processing process, and only the existing processing equipment cannot meet the requirements of the non-woven fabric. Textile processing needs

Embodiment 1

[0031] This embodiment discloses a preparation process of antibacterial medical non-woven fabric, comprising the following steps:

[0032] Step S1, using a preparation system to prepare a non-woven fabric, and sequentially opening, carding, laying and spunlace the composite raw material fibers to obtain a non-woven fabric;

[0033] Step S2, drying the non-woven fabric prepared in step S1, controlling the drying temperature to 95-120°C, and after drying, the moisture content is 20-30%;

[0034] Step S3, washing the non-woven fabric prepared in step S2 three times with water, and neutralizing it with 3% acetic acid solution, so that the pH value of the non-woven fabric is 5.0-8.0;

[0035] Step S4, drying the non-woven fabric prepared in step S3, controlling the drying temperature to 95-120°C, and controlling the moisture content to 8-10%;

[0036] Step S5, cooling and rolling the nonwoven fabric obtained in S4.

[0037] In step S1, the composite raw fiber includes 40-50% by m...

Embodiment 2

[0041] This embodiment discloses another antibacterial medical non-woven fabric preparation process. On the basis of Example 1, a preparation system is used to prepare the non-woven fabric in step S1. Refer to figure 1 shown.

[0042] The preparation system includes three sets of spunlace devices, the spunlace devices include a conveying mesh belt 36 on which several spunlace components 37 are arranged, and several spunlace components 37 are evenly arranged along the conveying direction of the conveying mesh belt 36 , Adjacent spunlace devices are connected by guide rollers 39 to transport the non-woven fabric.

[0043] When the non-woven fabric passes through the position between the conveying mesh belt 36 and the spunlace head 38, the spunlace head 38 can spunlace the fibers in the non-woven fabric, so that the fibers are entangled and form a stable fabric structure; The spunlace strength in the three sets of spunlace devices decreases sequentially with the delivery sequenc...

Embodiment 3

[0045] This embodiment discloses another antibacterial medical non-woven fabric preparation process, on the basis of embodiment two, refer to Figure 1-Figure 2 To illustrate, the hydroentanglement head 38 in the hydroentanglement device is further optimized to enhance the effect of hydroentanglement.

[0046] The spunlace device uses spunlace reagents to spunlace various fibers in the non-woven fabric, wherein the spunlace head 38 is provided with a high-pressure liquid chamber 2, which is set in the width direction of the non-woven fabric, and is placed in the high-pressure liquid A filter tube 4 is set in the cavity 2, and the water inlet position in the high-pressure liquid cavity 2 is located in the filter tube 4, so that the filter tube 4 can filter the impurities in the spunlace reagent and prevent the impurities in the spunlace reagent from clogging the spunlace head 38 .

[0047] Two inverted cone-shaped baffles 3 are installed at the lower part of the high-pressure ...

Abstract

The invention discloses an antibacterial medical non-woven fabric and a preparation process thereof, and relates to the technical field of non-woven fabrics. The preparation process comprises the following steps that S1, a non-woven fabric is prepared by adopting a preparation system, and opening, carding, lapping and spunlace are sequentially performed on composite raw material fibers to obtain the non-woven fabric; S2, the non-woven fabric prepared in the step S1 is dried, the drying temperature is controlled to be 95-120 DEG C, and after drying treatment, the moisture content of the non-woven fabric is 20-30%; S3, the non-woven fabric prepared in the step S2 is washed with water for three times, and the non-woven fabric is neutralized with an acetic acid solution with the concentration of 3% to enable a pH value of the non-woven fabric to be 5.0-8.0; S4, the non-woven fabric obtained in the S3 is dried, the drying temperature is controlled to be 95-120 DEG C, and the water content is controlled to be 8-10%; and S5, the non-woven fabric obtained in the step S4 is cooled and rolled. According to the antibacterial medical non-woven fabric and the preparation process thereof, a special antibacterial process and a fiber material are adopted, so that the non-woven fabric has a certain antibacterial effect and is more suitable for being used in the medical field.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, more specifically, it relates to an antibacterial medical non-woven fabric and a preparation process thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. The fibers or filaments are formed into a web through airflow or machinery, then spunlace, needle punched, or hot-rolled for reinforcement, and finally finished to form a non-woven fabric. [0003] For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, ...
