Problems solved by technology

[0002] In the existing technology, there are too many disadvantages of disposable protective clothing, which are as follows: 1. The protection level of disposable protective clothing itself is very low, and its water resistance is generally only 17 cm, which belongs to the lowest level of protection; 2. The material strength is low and easy to wear. damaged
Infected patients will pull the medical staff due to fear, convulsions, convulsions, etc., resulting in damage to the protective clothing, which is more likely to cause infection of medical staff; 3. The use time is short, and it needs to be replaced within 6-8 hours; 4. Disposable protective clothing The air permeability of the protective clothing is poor, and the medical staff wear it for several hours, which is hot and sweaty, which greatly reduces the physical consumption of the medical staff, which is not conducive to the health of the medical staff and the progress of the treatment work; During the incineration process, there is a risk of infection for people in contact with each link; carcinogens such as dioxins are also produced during the incineration process, resulting in environmental pollution; 6. The cost of disposable protective clothing is high

Embodiment 1

[0049] Embodiment 1: A kind of reusable protective clothing

[0050] The parameters of the protective clothing are as follows:

[0051] (1) Liquid barrier function, anti-seepage water pressure (GB / T 4744-2013 (60cm H 2 O / min, water temperature: 20°C)):

[0052] (1) Hydrostatic pressure of new protective clothing (cm H 2 O )≥1100cmH 2 O.

[0053] (2) The hydrostatic pressure (cm H) of repeated use 100 times 2 O )≥40cmH 2 o

[0054] The water seepage resistance of all regions of the protective clothing of the present invention has reached the above standards.

[0055] / (2) Moisture permeability of medical composite materials used in protective clothing (GB / T 12704.2-2009 f method B (temperature: 38°C, relative humidity: 50%))

[0056] (1) Moisture permeability ≥ 2500g / (m 2 d)

[0057] (2) Moisture permeability ≥ 5000g / (m) after repeated use for 20 times 2 d)

[0058] (3) Moisture permeability after repeated use 100 times ≥ 8000g / (m 2 d)

[0059] / (3) Anti-synthet...

Embodiment 2

[0074] Example 2: A reusable protective suit

[0075] The protective clothing is obtained through the preparation of medical composite materials, and the specific steps of the manufacturing process of the medical composite materials are:

[0076] (1) Manufacture of flame-retardant polyester filament fibers

[0077] The air deformation process is used to reduce the hardness and smoothness of the surface of the polyester filament fiber. After the treatment, the polyester filament fiber is immersed in the flame-retardant finishing solution, and then undergoes pre-baking and baking processes to make the flame retardant on the fabric. deposition and crosslinking to obtain flame-retardant polyester filament fibers, and the polyester filament fibers are polyethylene terephthalate (PET) filament fibers;

[0078] The main component of the flame retardant finishing solution is a modified aluminum hydroxide flame retardant. The preparation method of the modified aluminum hydroxide flam...

experiment example

[0088] The overall cost of the protective clothing of the present invention is generally within 2,000 yuan, can be used repeatedly 100 times, and the cost of a single use is 20 yuan; after mass production, the overall cost is reduced, and the cost of a single use can reach about 15 yuan.
