What Are Surgical Gowns Made Of?
Surgical gowns (also called “hospital gowns”) are worn by doctors and nurses in the operating theater to perform a dual function of preventing transfer of microorganisms and body fluids from the operating staff to the patient, and also from patient to staff. Many of the performance requirements for surgical gowns are well documented.
As Class II medical devices, they have to fulfil the basic demands stipulated in the standard series (EN 13795, 2003, 2005, 2006). They are may be disposable or reusable. Disposable nonwoven surgical gowns have been adopted to prevent the release of pollutant particles into the air which is a probable source of contamination to the patient. Single use nonwoven medical gowns are becoming the first choice of healthcare professionals because they feel they are superior to reusables. They have confidence that they will be protected from infection. For various types of operations, different product qualities (performance classes) are defined as:
- High performance, for operations with a high risk of infection and penetration by liquids.
- Standard perfomance, for operations where these risks are lower.
What Are Hospital Gowns Made Of？
- What is the structure of hospital gowns?
Most of the gowns were constructed from 3 to 5 major pieces.Although many of the gowns had no seams at the side,they had front and back panels defined clearly by the sleeve placement. The fronts of the gowns were continuous with no seams or breaks in the fabric surface. This is extremely important as the front of the torso is a critical area for barrier performance.
The back was composed of two overlapping panels providing access for donning and doffing. Ties, used in various locations to secure the gowns, were typically nonwoven strips similar to the material used to construct the gown.
To close the body of the gowns, mechanisms were attached to the right and left back panels. The right back panel had an internal tie attached approximately 20” down from the shoulder. It also had an external tie attached about 20” from center back. The corresponding tie was on the shoulder. Several of the gowns had a location where the exterior tie was stitched onto the front panel for added strength and to restore the compromised barrier. The lest back panel had a tie located on the outside usually about 20” below the back neck in the center.
The necklines of the hospital gowns usually were closed by hook and loop tape, easy and convenient. The loop component of the taps was placed at the neckline of the left back panel. The corresponding hook component was found on the right back panel. The hook component is about 1.5” long, and the loop component 7” long providing great flexibility and accuracy in the neckling fit.
The sleeve edges were contained with a rib knit cuff stitched on at the wrist. In use, surgical gloves are worn pulled up over the cuffs, so it is important for the cuffs to fit snugly.
- What material are hospital gowns made of?
Unlike woven or knitted fabrics, the disposable gowns usually using the non-woven as the materials. Non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-woven have become an alternative to polyurethane foam.
SMS Non-Woven Fabric
The main fabric material for the disposable gowns is SMS, which is soft, comfortable and breathable for clinicians dressing. Three layers of spunbond polypropylene ensure an extraordinary flexibility and drapeability, provide tough abrasion resistance and cloth like feel, and two layers of meltblown polypropylene form an efficient barrier against bacteria, as an exceptional microbial barrier.
PP and PE composed the reinforced sterile, it can help protect the medical workers from being fected by the blood or body fluid and other infectious material effectively.
Wood pulp-Biodegradable Non-woven Fabric
Wood pulp non-woven fabric is a new type of material which is extremely attractive due to its cloth-like texture and softness, advanced splash-resistant barrier gives you both breathability and great protection. Hospital surgical gowns made of this fabric are also popular for people.
At the same time, this fabric has good bacteria and biodegradability. It is made of wood pulp as a raw material, non-toxic and harmless. In addition, It also can be completely degraded after being buried in the soil for one year, and will not cause any harm to the environment. So - the world of surgery can also be green.
For many customers, surgical gowns are daily worn, so a truly comfortable surgical gown is appreciated and readily worn.
