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.
