Hangzhou Weston Manufacturing Co., Ltd. R&D team made lots of testing and research in past years, and developed some great nonwoven fabric products. Among them, the spunlace waterproof woodpulp polyester consolidated fabric is a star.
EN13795 Dupont Softesse Similar surgical gown nonwoven cloth

Weston Surgitex®--EN 13795 standard medical application disposable cloth

Comparing with DuPont Sontara Softesse
Weston produces 55% woodpulp 45% polyester laminated spunlace at high standard. We imported a separate production line which is designed only to produce medical fabrics, such as disposable fabric for surgical gown, drapes and medical disposable bed sheets. The products are similar with DuPont Sontara or DuPont Softesse in some points, but differ in some parts. Weston learnt from great forefathers and also developed its own features according to upgraded demand of modern medical and health industry.

Here are several important actions we took:

First, this production line was placed in a specially designed cleanroom workshop, so as to ensure the fabric is produced under the Europe standard of EN 13795. The decoration of the workshop, wearing and dress of workers, floor, all of these are in consistent with EN 13795 standard.
Second, another carding machine was added in this production line, so there are two carding machines in this medical spunlace production line. It aims to produce cross lapping spunlace to be laminated with woodpulp papers. This is rare in the world. It consolidates fabric strength in MD and CD. It is known that surgical gown should be well-textured and durable enough to be protective. No surgeons shall take the risk of wearing a surgical gown that would get unraveled during a surgery. So Weston Surgitex® gives double insurance for both surgeons and patients’ safety.
In order to make out if Weston Surgitex® conforms with modern medical standard and ensures good clinical practice, we invite the third parties to test the fabrics. The result is that it is in line with the Europe EN 13795 standard.
Standards for medical devices aim at improving the quality of the products on the market and are therefore vital for good clinical practice.
The European Standard EN 13795 is the first standard for users and suppliers of single-use and multiple-use products, with mutually agreed test methods to be applied to all fabrics on the market, irrespective of their construction.
This standard provides an excellent tool for users to compare product performance. EN 13795 is an EU recognized harmonized standard.

EN 13795 specifies requirements for

• Single-use and reusable surgical

• Drapes (including equipment

• Covers as sterile field), surgical

• Gowns and clean air suits.

The standard sets out the technical requirements of the products, responsibilities of manufacturers, processes and provides information for the use of their devices, intended to prevent the transmission of infective agents between patients and clinical sta? during surgical and other invasive procedures.
In order to comply with EN 13795, the devices have to meet a number of technical requirements as demonstrated by the following test conditions.
Weston Surgitex® performance:

1. BARRIER TEST

1).Resistance to dry microbial penetration (EN ISO 22612)

Objective: determine the ability of the dry fabric to resist penetration of particles carrying micro-organisms.
Method: the test fabric is placed in a container with talc contaminated with Bacillus subtilis. Any talc that penetrates the fabric is captured on a sedimentation plate underneath and incubated.
Measure: number of colonies formed after incubation.



2). Resistance to wet microbial penetration (EN ISO 22610)
Objective: determine a fabric’s resistance to penetration of bacteria in a liquid while being subjected to mechanical rubbing.
Method: the test fabric is subjected to material contaminated with Staphylococcus aureus suspension. If penetration occurs, bacteria will collect on to an agar surface and be incubated.
Measure: number of colonies formed after incubation, expressed in Barrier Index (BI).



3).Resistance to liquid penetration (EN 20811)

Objective: estimate the resistance of fabrics to liquid penetration by water under constantly increasing hydrostatic pressure.
Method: one side of the fabric sample is subjected to purifed water pressure which is increased at a constant rate until leakage appears on the other side of the fabric sample.
Measure: the head height results are recorded in centimeters of water pressure on the fabric sample



2. LINTING TEST

CLEANLINESS – PARTICULATE MATTER & LINTING (ISO 9073-10)

1). CLEANLINESS – PARTICULATE MATTER

Objective: estimate linting of the fabric in a dry state, prior to twisting and compressing.
Method: fabric is placed in a chamber and number particles are calculated.
Measure: number of particles from 3µm to 25 µm, as an index for Particulate Matter (PM) expressed as log10.



2).LINTING

Objective: estimate linting of the fabric in a dry state, after twisting and compressing.
Method: the same fabric sample is twisted and compressed.



Measure: number of particles from 3µm to 25µm generated after the twisting and compressing, expressed as log10 of the count value.



3. 1).BURSTING STRENGTH – DRY & WET (EN 13938-1)

Objective: determine the resistance of a fabric to puncture under dry and wet conditions.

Method: a fabric sample is clamped over an expansive diaphragm by means of a circular ring. Fluid pressure is applied at a constant rate on the other side of the diaphragm causing distension of the diaphragm and fabric until the fabric bursts.
Measure: strength at burst, in kPA


2).TENSILE STRENGTH – DRY & WET (EN 29073-3)

Objective: determine the ability of a product to withstand fabric tearing under dry and wet conditions.

Method: a strip (specifed length and width) of fabric is held in place with clamps on a

machine that pulls the strip apart at a constant rate of extension.

Measure: amount of force applied to break the strip, in Newton.

Why Surgitex®?

Surgitex® (developed by Weston Manufacturing) is a unique material that combines the strengths of non-woven fabrics and linen and offers barrier and drape features. It is produced by the spunlace/hydro-entangling process in which high-pressure water is utilized to enmesh the fibers with each other without the use of adhesives or thermally fused resins. This process gives the material the following features:

1. The fibers are tightly enmeshed with each other, producing a material with no holes and resulting in excellent barrier performance.

2. The material is soft and drapes very well.

3. A water-repellent treatment can be applied to prevent blood or other body fluids from soaking into the fabric.

4. The material consists of wood pulp and polyester (PET), a material used in food packaging. (The pulp is obtained from trees that are planted and harvested under strict control.)

5. The material can be cut into various shapes without unraveling or creating lint.

6. Since no adhesives or thermally fused resins are used, there is no concern regarding residual chemicals or binder material seepage caused by heat from friction.

This is why we chose Surgitex®.

When the surfaces of Surgitex® and linen are compared under a microscope, you will notice that there are hardly any spaces between the fibers in Surgitex® (photo 1).

Meanwhile, linen has holes that average 50µm in size where the threads intersect (photo 2).

Comparison of a 50µm hole and the sizes of various bacteria

Colibacillus (3 x 0.6µm)

Diphtheria (gram-positive)(4 x 0.7µm)

Staphylococcus(1µm)

Anthrax(8 x 2µm)

Hole(50µm)


Specification:

Grammage range: 65gsm-100gsm;

Color: blue, deep blue, customized color;

Width range: 20cm-210cm
