Non-woven fabrics characteristics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic, and non-irritating. However, only these characteristics are not enough to meet the requirements of different products in various fields, which require specific treatment of non-woven fabrics to meet customer requirements for various exception properties of non-woven fabrics.

SMS Non-woven fabrics are produced by a combination of spun-bond and melt-blown processes. With waterproofing, isolation, and air permeability. When SMS non-woven fabric is used in the medical field, it is commonly used to produce: surgical gowns, protective coveralls, patient gowns, disinfectant gowns, isolation gowns, surgical drapes, medical masks, shoe covers, etc.

However, ordinary SMS cannot wholly block alcohol, blood, and oil, so it is necessary to carry out special treatment for SMS. The processed non-woven fabric has the functions of anti-alcohol, anti-blood, anti-oil, and antistatic. It better improves the safety of medical use.

2. Antistatic treatment

The moisture regain of non-woven fabrics (The weight of water in the product as a percentage of its dry weight) is relatively low, and it is easy to produce static electricity in production and use. If on the operating table, sparks from static electricity can cause an explosion of anesthetics, harming doctors and patients. Therefore, antistatic treatment is required for such products.

3. Flame retardant treatment

Flame retardant non-woven fabric is the process of producing non-woven fabric, adding flame retardant by improving the ignition point of raw materials or preventing the combustion of raw materials to flame retardant.

There are three kinds of flame retardant non-woven fabric: polyester flame retardant non-woven fabric, polypropylene flame retardant non-woven fabric, and viscose flame retardant non-woven fabric.

Flame retardant non-woven fabrics are widely used in the production of home decoration products, industrial products, agricultural products, medical cleaning products, and aviation supplies. Among them, medical flame retardant non-woven fabrics can be used to produce surgical gowns, protective coveralls, wet wives, disinfectant wrap cloth, etc.

4. Hydrophilic treatment

Non-woven fabrics are generally not hydrophilic. To achieve the hydrophilic function of non-woven fabric, you can add the hydrophilic agent to the production process of non-woven fabric. The produced non-woven fabric is called hydrophilic non-woven fabric. Hydrophilic non-woven fabric has good water absorption and can be used to promote baby diapers, protective clothing, disinfectant cloth, masks, and so on.

5. Photocatalyst effect treatment

Non-woven fabric in the production process, the photocatalyst fiber processing liquid is added to the raw material that the products produced have antibacterial, deodorization, antifouling, air purification, and other functions. The usage of it is to make masks and air filters.

6. Uv resistant treatment

Uv resistant non-woven fabric is to add a certain proportion of anti-UV agents in the raw material so that the non-woven fabric has good anti-UV and anti-aging performance.

Uv resistant non-woven fabric is acid and alkali-resistant, non-toxic, non-radiation breathable cavity, soft and comfortable. The usage is in agricultural cover cloth, automobile cover, and other fabrics which require sun protection and anti-aging.

7. Coating process of non-woven fabric

Spunbonded PP non-woven fabrics and SMS laminated non-woven fabrics can be coated. The coated process is developed to make non-woven fabrics waterproof. The process is blowing film, film, casting film, shower film, and breathable film. It is a variety of technology in the non-woven fabric with PE material. In the different coating processes, the final effect is also different.

Summary

These treatment processes are not single. The same product may be used in one or more treatment processes. For example, surgical drape requires water absorption, hydrophilic, anti-alcohol, anti-blood, anti-oil, and antistatic electricity, and other characteristics. Therefore, the production of surgical drapes needs to use hydrophilic treatment, three anti-treatment, antistatic-electricity, and film technology.
