Characteristics of surgical gown

Pure cotton is a natural fiber with good air permeability, good hand feeling and low price. 60 x 60/20's x 20's and 108 x 58/20' SX 20' s are mainly used. At present, more than 90% of all medical institutions in China mainly use cotton surgical gowns, but in western countries, the requirements for surgical gowns have been regarded as the most important normative focus. Although cotton is breathable, it has no barrier protection function. In case of major surgery, massive bleeding or need to use a lot of liquid to wash, the surgical gown will be soaked by splashing liquid, and then penetrate into the inner layer to brush the glove. With various pathogens that may be carried, including HBV (hepatitis B virus), HCV (hepatitis C virus) and HIV (HIV), medical staff will face greater risk of infection. With the improvement of control and protection awareness, manufacturers and hospitals have improved this problem from the aspects of materials and use respectively. In the case of cotton surgical gown, the manufacturer may use post-treatment to add water splashing agent or multi-layer combination (adding moisture permeable and waterproof fabric in the middle) to reduce the absorbed liquid. In the hospital, the medical staff in the operating room may stick a waterproof glue membrane or a water collecting layer to collect the liquid from the operation to avoid contact with the human body. In addition, in large-scale surgery, when it is expected that a large amount of body fluids may be produced, if medical staff choose to wear cotton surgical gowns, they should wear waterproof gowns inside the surgical gowns to prevent the liquid adsorbed on the surgical gowns from infiltrating.

High density fabric

Mainly 75d/70f or 75d/ 144f polyester fiber, with warp and weft densities of 150- 170 and 100- 120, respectively, and the fabric surface is (0.5-1). The antistatic effect obviously improves the comfort of the surgical gown. This surgical gown has the advantages of hydrophobicity and barrier function, and it is not easy to produce dust and cotton surgical gown. Moreover, the washable times of repeated use are 50-70 times that of cotton surgical gowns. The characteristics of light weight and non-absorption of this kind of surgical gown reduce the washing cost, so the overall cost is also reduced, which is also an important factor to increase the use of polyester fiber surgical gown at present.

Multilayer bonded fabric:

With the continuous improvement of textile technology, many new materials are gradually applied to various medical fabrics. Combining the advantages of cotton and chemical fiber, the middle layer is bonded with PU, PTFE or Goretex film, which makes the surgical gown have excellent protective performance and comfortable air permeability, and can effectively block the penetration of blood, bacteria and even viruses. Since 2003, medical institutions in Europe and America began to promote the use.

Disposable surgical gown material:

1. Polypropylene spunbonded fabric: After antibacterial and antistatic treatment, this material can be made into antibacterial and antistatic protective clothing. Polypropylene spunbonded cloth can replace traditional cotton cloth. Compared with traditional cotton protective clothing, polypropylene spunbonded protective clothing is undoubtedly a great progress. Because of its low price and disposable use, it can greatly reduce the cross-infection rate, and has been widely promoted abroad for a long time. However, such materials have low hydrostatic pressure resistance and poor virus particle blocking efficiency, and can only be used as common protective articles such as sterile surgical gowns and disinfection bags. 2. Spunlaced fabric composed of polyester fiber and wood pulp: this material is soft to the touch, close to traditional textiles, and can be treated with three defenses (anti-alcohol, anti-blood and anti-oil), antistatic and antibacterial, and can be disinfected by "Y" ray, so it is a good medical protective clothing material. However, it is not an ideal protective clothing material because of its low hydrostatic pressure resistance and poor barrier efficiency to virus particles.

3. Polypropylene spunbonded-meltblown-spunbonded composite nonwovens (namely SMS or SMMS):

Melt-blown cloth has the characteristics of fine fiber diameter, large surface area, fluffy and soft, good drape, low filtration resistance, high filtration efficiency and strong hydrostatic pressure resistance, but its low strength and poor wear resistance limit its application field to some extent. The fiber linear density of spunbonded fabric is high, and the web is composed of continuous filaments, and its breaking strength and elongation are much greater than that of meltblown fabric, which can just make up for the shortcomings of meltblown fabric. SMS products not only have the inherent high strength and wear resistance of spunbonded layer, but also the middle meltblown layer improves the filtration efficiency, barrier performance, particle penetration resistance, hydrostatic pressure resistance, shielding performance and appearance uniformity of products, thus achieving good filtration, liquid resistance and opacity. This material has the following excellent characteristics: ① uniform and beautiful appearance; ② High hydrostatic pressure resistance: ③ Soft hand feeling; ④ Good air permeability; ⑤ Good filtering effect; ⑥ Strong acid and alkali resistance. In addition, SMS nonwovens can also be treated with anti-alcohol, anti-blood, anti-oil, anti-static, anti-bacteria and anti-aging to meet the needs of different uses. Therefore, SMS nonwovens are widely used to make high-grade surgical gowns at home and abroad.

application area

Can be used for surgery and patient treatment; Epidemic prevention inspection in public places; Disinfection of virus-contaminated areas; It can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other fields.
