    4. 4. IntroductionThe use of nonwovens in medical arena goes back to the time ofSecond World War when need for new and large volumes ofmedical product had arisen. In several reports published,nonwovens were regarded as the most effective materials forbacterial barriers.Nonwovens give a performance much better than woven in termsof cost-effectiveness, disposability etc. In hospitals, cross-contamination is always one of the biggest problems which wereattributed largely to re-using of woven gowns, masks and othersimilar articles which would get contaminated and spread thegerms. Nonwovens are more cost effective alternative which aredisposable and reduced the problem of cross-contaminationgreatly.

    6. 6. Why nonwoven for medical products???? The properties which make nonwovens the best choice for medical products are:• Excellent barrier properties• Superior efficiency• Better performance (comfort, porosity, thickness and weight, water vapor transmission, air permeability etc.)• Increased protection for user (better physical properties like tensile, tear resistance, abrasion resistance etc.)• Easy to sterlize.• Economical manufacturing process.

    15. 15. Manufacturing ProcessVarious techniques are used for manufacturing of nonwovens butsome of the techniques that are used specially for the Medicalapplications point of view are as follows:Spun bondingSpunlacingMeltblowingNeedle punchingWet laidDry laid
    16. 16. Spun bondingSpun bonding is used when more strong webs are needed.Webs produced are soft, porous and dimensionally stable.Spun bonding is mostly used for products like :- Face masks Head wears Shoe covers Bed linens and Disposable clothing .

    19. 19. Characteristics and Properties of Spun Bonded Fabrics The characteristics of spun bonded web are:-• The fibrous structure is random.• Opacity/area of the web is high.• The web weight range between 10- 200 g/m2.• Typical web thickness lies between 0.2- 1.5 mm.• Good fray and crease resistance.• High tear strength.• High strength compared to other nonwoven, woven, and knitted structures.
    20. 20. ApplicationIn medical applications many traditional materials have been replaced byhigh performance spun bonded webs. The particular properties of spunbonded webs, which are responsible for medical use, are: Breathability Resistance to fluid penetration Lint free structure Sterilizability and, Impermeability to bacteria.Medical applications include: disposable operating room gowns, shoecovers and sterilizable packaging.

    22. 22. Post processes Post process for medical nonwovens is to give the product a suitable finish for its specific end use. The different types of finishes used in medical nonwovens are:• Soil Release Agents: For bed linens, gowns and apparel which are designed for multiple usages. May also be used on curtains, blankets etc.• Softeners: To make the webs feel soft against the skin. May be used for disposable pillows, bed sheets etc.• Water repellents: Used for bed sheets for kids, barrier apparel etc.• Flame Retardant Finishes: Used for bed linens, curtains, apparel, lab coats etc.• Antibacterial Finish: Very commonly applied to gauzes, dressings and sutures. The most popular one is silver nanocrystal finish.

    24. 24. ConclusionMedical textile market is totally saturated with nonwoven productstoday. Nonwovens, because of their easily modifiable propertiesand excellent performance have become indispensable in this field.Medical and Hygiene sectors combined together consume morethan 90% of the total nonwoven production in US. On the otherhand, in developing countries of Asia, Africa and South America,demand for medical nonwoven is increasing significantly as aresult of a fast-growing, young, health-conscious population. Infuture, the demand of nonwovens in medical field is expected togrow steadily.
