Surgical Gown

Nov. 06, 2018

Material and process


Surgical gown are mainly classified into repetitive surgical gowns and disposable surgical gowns depending on the use. Repeated use of surgical gowns are mainly made of ordinary cotton fabric, high-density polyester fabric and PE, TPU, PTFE multi-layer laminated film composite surgical gown. Disposable surgical gowns are mainly SMS\SMMS surgical gowns, SMS or SMMS non-woven surgical gowns, and reinforcing sheets are non-woven composite materials.


Characteristics


High density fabric

Mainly made of 75d/70f or 75d/144f polyester fiber, the warp and weft density is 150-170/inch and 100-120/inch respectively, and the fabric surface is filled with conductive fiber or carbon fiber every (0.5-1)cm. The fabric has an antistatic effect (similar to a dust-free fabric). The antistatic effect makes the comfort of the surgical gown significantly improved. This type of surgical gown is hydrophobic, has a barrier function, and is not easy to produce micro-dust and cotton surgical gowns. Moreover, the number of repeated washings is 50-70 times higher than that of cotton surgical gowns. The light weight and non-absorbent properties of this type of surgical clothing reduce the cost of washing, so the overall cost also decreases. This is also the current polyester fiber surgery. An important factor in the increase in the use of clothing.


Multi-layered 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 laminated with PU, Teflon (PTFE) or Goretex film, which makes the surgical gown have excellent protective performance and comfortable breathability, which can effectively block blood and bacteria. Even the penetration of the virus. In 2003, European and American medical institutions have been promoted and used.


material

1. Polypropylene spunbonded cloth: This kind of material can be treated by antibacterial and antistatic, and made into antibacterial protective clothing and antistatic protective clothing. Polypropylene spunbond fabric can replace traditional cotton. Compared with traditional cotton protective gown, polypropylene spunbond protective clothing is undoubtedly a big improvement. Because of its low price and one-time use, it can greatly reduce the cross-infection rate, and it has been widely promoted abroad for a long period of time. However, the anti-hydrostatic pressure of this material is relatively low, and the barrier efficiency against virions is relatively poor, and it can only be used as a general protective equipment such as sterile surgical gowns and sterilized wraps.


2. Polyurethane fiber and wood pulp composite leeches: This material is soft to the touch, close to traditional textiles, and can be treated with three anti-alcohol (anti-alcohol, anti-blood, oil-resistant) and antistatic, antibacterial, etc. "Y" rays are disinfected and are a good medical protective clothing material. However, its anti-hydrostatic pressure is relatively low, and the virion resistance is also poor, so it is not an ideal protective clothing material.


3. Polypropylene spunbond-meltblown-spunbond composite nonwoven fabric (ie SMS or SMMS):

The meltblown cloth is characterized by fine fiber diameter, large surface area, fluffy, soft, good drape, low filtration resistance, high filtration efficiency, strong anti-hydrostatic pressure, but low strength and poor wear resistance, which is limited to a considerable extent. The development of its application field. The spunbond fabric has a higher density of fibers, and the web is composed of continuous filaments. The breaking strength and elongation are much larger than that of the meltblown fabric, which can make up for the deficiency of the meltblown fabric. The SMS product has both the inherent high-strength wear resistance of the spunbond layer, and the intermediate melt-blown layer improves the filtration efficiency, barrier properties, particle penetration resistance, hydrostatic pressure resistance, shielding and appearance uniformity of the product. Good filterability, liquid barrier and opacity. This material has the following excellent characteristics: 1 uniform and beautiful appearance; 2 high anti-static water pressure capacity: 3 soft hand feeling; 4 good gas permeability; 5 good filtration effect; 6 acid and alkali resistance. In addition, the SMS nonwoven fabric can be treated with three anti-alcohol (anti-alcohol, anti-blood, anti-oil) and anti-static, anti-bacterial, anti-aging, etc., to meet the needs of different uses. Therefore, SMS nonwovens are widely used at home and abroad to make high-end surgical gowns.
