Medical Textiles

Medical textiles is an emerging sectorof technical textiles industry and itsgrowth is increasing due to constant

improvements in healthcare as well asinnovations in the textile field.

They are one of the major end-usesof nonwovens industry.

NEED OF SURGICAL GOWNS

Surgical gowns, surgical drapes and cleanair suits are used:

to protect patients and hospital staff fromwound infections.

to protect nurses, surgeons and the surgicalteam from liquid contaminations.

to diminish the risk to the operating stafffrom blood-borne infective agents carriedin blood or body fluids.

TEXTILE MATERIALS FOR DISPOSABLE

Textile materials used for these fabricsinclude:

Single use disposable textile fabrics include: Spun lace (combination of polyester fibers and

cellulose) &

Polypropylene or polyester

SMS (3-layered structure of fibres, in the sequenceSpun bond - Melt blown - Spun bond)


10/30

10

TEXTILE MATERIALS FORREUSABLE

Polyester, Cotton & Linen are the textile fibers for reusablegowns

Surgical textiles are regulated by EN 13795 series ofstandards in Europe

Surgical gowns, drapes and clean air suits are made to

completely cover the surgeon's front and back as well as hisarms

PROPERTIES OF TEXTILEMATERIAL

Requirements of textile material for medicalapplications

Biocompatible Good resistance to alkalis, acids and micro-

organisms

Good dimensional stability

Elasticity Free from contamination or impurities

Absorption / Repellency

MANUFACTURING TECHNIQUEOF SURGICAL GOWN

WET LAYING & SPUNLACE

BONDING


13/30

WET LAYING

Wet-laid nonwovens are nonwovens in whichfibers to be used are suspended in water.

A major objective of wet laid nonwoven manufacturingis to produce structures with textile-fabriccharacteristics, primarily flexibility and strength.

13


14/30

WET LAYING

There are three characteristic stages in themanufacture of nonwoven bonded fabrics by thewet-laid method

1. Swelling and dispersion of the fiber in water; transportof the suspension on a continuous traveling screen.

2. Continuous web formation on the screen as a result offiltration.

3. Drying and bonding of the web14

Principle of spunlace bonding

Spunlace or hydroentanglement isweb bonding technology, whichuses fine, high pressure jets ofwater to cause the fibres to

interlace. Water jet due to high kinetic

energy reorientates fibers accordingto the shape of the support screen.

Features of SPUNLACEDFABRIC

Very good textile drape (low stiffness) and very soft handle

Strenght is much higher than after mechanical needling (for the

some area weight); similar to woven textiles

Uniform surface due to more fine interlacing of fibers.

Very high textile production: up to 500 m/min for wetlaid and

spunbond (meltblown); textile width up to 6000 mm.

TERMINOLOGY

Cleanliness- Freedom from particles that are contaminating amaterial and can be released but are not generated bymechanical impact

Critical Product - A product area with a greater probability tobe involved in the transfer of infective agents to or from thewound, e.g. front and sleeves of surgical gowns

Drape ability -Ability of a material to conform to a given shapeor object

Infective Agent - Micro-organism that has been shown to causea wound infection or that might cause infection in a member ofthe surgical team or the patient

Linting - Release of fiber fragments and other particles during

handling and use


22/30

REUSABLE GOWNS

Advantages Lowest microbial barrier Mechanical resistance Drape ability Comfort Minimization of bio-

medical waste. Substantial cost savings. Clinician preference for

reusable Materials (e.g. comfort,

color, feel, etc.) More environment

friendly

Consistent quality

Dis-Advantages

Washing residues

Washing costs (laundry)

Highest linting Highest liquid penetration.

22


23/30

DISPOSABLE GOWNS

Advantages

Higher microbial barrier Lower liquid penetration Lowe linting Comfort Minimisation of bio-

medical waste Better quality control &

consistency

Easiness of use No washing No risk of contamination Very little rejections.

Dis-Advantages

Barrier to change to newdraping system

Increased bio-medical

wastes Less environment friendly

Less clinical preference

Disposal costs(landfill/incineration)

More costs due to singleuse

Poor drapeability

Lower mechanicalresistance

Not reusable23

STRENGTH

The strength of surgical textiles is especiallyimportant because they are subjected to highmechanical stress levels when used

Even the best possible barrier properties are of

little use if the material tears or bursts duringuse

In the standard, strength is measured in twoways :

+ bursting strength+ tensile strength

Reusable products perform better in bothcategories


25/30

25

BURSTING STRENGTH

Bursting strength describes the strengthof the product in all directions of thematerial

Heavy mechanical action, e.g. bent arm atelbow

It is measured in a dry and a wet state


26/30

26

TENSILE STRENGHT

Resistance to tearing describesthe strength of the product in thelongitudinal (machine or warp)

and horizontal direction (weft) For example, as surgeon bends

forward, the gown can be

stretched in different directionsat shoulder and back

It is measured in a dry and a wetstate


27/30

27

COMFORT

Wear comfort is not just a convenience; itis a physiological requirement

It is of particular concern to the OR team,whose efficiency needs to be supportedrather than impaired

However, the drape should also offeradequate physiological comfort in order tobenefit the patient

Opportunities & Challenges

Ahead

Opportunities

Consumption is increasing rapidly

Pvt. Hospital chains are growing

Doctor/patient awareness for hygiene is increasing

Medical tourism

Challenges

China has become very strong in most of Healthcare &hygiene products

There are very few standards in place leading tosubstandard quality products being used.
