Embodiment 1

[0020] A preparation method of antibacterial repair type medical non-woven fabric, comprising the following steps:

[0021] (1) Opening: Wash tea fiber, acetate fiber, casein fiber, and soybean protein fiber twice with sterile water, heat and open in water after mixing to obtain open fiber; the antibacterial component of tea fiber is inside the fiber, It can improve the long-lasting antibacterial effect, the acetate fiber increases the adhesion of the fiber, and the soybean protein fiber and casein fiber are rich in amino acids and proteins, which help the skin heal;

[0022] (2) Combing into a web: Firstly, vibrate the opened fiber for 24 minutes under ultrasonic frequency of 40 kHz, settle for 8 min, then use ultrasonic frequency of 25 kHz for 5.5 min, settle for 42 min to obtain a mixed fiber web; use two frequency ultrasonic waves to card the fibers , the oscillating waves generated by it can evenly disrupt the distribution of fibers, and the fiber web formed after natural...

Embodiment 2

[0034] Present embodiment 2 is compared with embodiment 1, and step changes in the following aspects:

[0035] For the heating and opening described in step (1), the temperature is 55°C and the time is 44 minutes.

[0036] The opening fiber described in the step (1), the mass fraction of its each preparation component is:

[0037] 37 parts of tea fiber, 13 parts of acetate fiber, 10 parts of casein fiber, and 8.5 parts of soybean protein fiber.

[0038] Step (2) combing into a network, its parameters are:

[0039] Vibrate for 25 minutes under ultrasonic frequency of 40kHz, settle for 9 minutes, then use ultrasonic frequency of 25kHz for 6.5 minutes, settle for 44 minutes.

[0040] Step (4) atomized spunlace, its parameters are:

[0041] The spraying pressure of the atomized water is 21kPa, the front side is sprayed for 4 minutes, and then the reverse side is sprayed for 3 minutes, and the number of alternating spraying cycles of the front and back sides is 6 times.

[0042...

Abstract

The invention discloses a preparation method of an antibacterial repairing type medical non-woven fabric. The preparation method is characterized by including: (1) opening: cleaning blend fibers in bacteria-free water for 2-3 times, and heating for opening; (2) combing to form a net: oscillating the blend fibers by ultrasonic waves with frequencies of 40 kHz and 25kHz, and settling to obtain a blend fiber net; (3) atomized water spraying: using pressurized atomized water to spray the front side and the reverse side of the blend fiber net; (4) drying: drying the blend fiber net in a low temperature after being sprayed by the atomized water; (5) preparing a bamboo fiber layer: preparing the dried blend fiber net into a bamboo fiber net layer according to the steps from (1) to (4); laminating by heat sealing: overlaying a tea fiber net layer with the bamboo fiber net layer, and adding medicament powder prior to laminating. The preparation method has the advantages that the prepared antibacterial repairing type medical non-woven fabric is uniform in thickness, high in stretchability, long in sterilizing effect lasting time and capable of healing a wound quickly and removing wound scars after being used.

Description

technical field [0001] The invention belongs to the technical field of textile processing, and in particular relates to a preparation method of an antibacterial repair type medical nonwoven fabric. Background technique [0002] Non-woven fabrics are non-woven fabrics that directly use polymer chips, short fibers or filaments to form fibers through airflow or machinery, and are processed to form non-woven fabrics. The process is short, high output, low cost, and many sources of raw materials , and has the characteristics of moisture-proof, breathable, flexible, easy to decompose, non-toxic and non-irritating; non-woven fabrics are mainly processed with polypropylene, polyester, nylon, and viscose fibers. Due to the excellent characteristics and low processing cost of non-woven fabrics, they are widely used in the fields of medical treatment, home decoration, clothing and industrial fabrics. Non-woven fabrics are used in the medical field, and their traditional processing raw...
