SMS Non-Woven Fabrics

WHAT IS SMS NON-WOVEN FABRICS? A TO Z COMPLETE GUIDE

A popular variant of non-woven fabric which is high in the present scenario is SMS (Spunbond-Meltblown-Spunbond) fabric. SMS Fabric material was particularly in high demand during the COVID-19 period. This material has a good demand in the market because of its protective features and enhanced strength, especially in healthcare facilities and industrial settings.

SMS fabric is made of three layers: two outer shells of spun-bond polypropylene to provide strength and a filtration layer on the inside of this containing melt-blown polypropylene. The two types give high tensile strength, tear resistance, and an excellent barrier property. It is also waterproof, dustproof, and has antimicrobial properties, making it suitable for manufacturing medical equipment like gowns, face masks, coveralls, and many others.

It also protects users from disease-causing microorganisms through transmission while offering high levels of comfort when wearing it. It is also used in the production of hygiene products such as tissues, wipes, surgical drapes for surgery, and protective clothing in different industry settings.

SMMS Fabric

The material of SMMS fabric is also called spunbond-meltblown-spunbond, which is a type of nonwoven fabric that is made from spunbond and melt-blown processes. The spunbond layer brings strength and stiffness to the layer and the melt-blown layer is responsible for the filtration and barrier properties of this layer. This process produces a highly functional material that finds application in many areas including medical protective wear, surgical masks, and industrial protective coverings amongst others. SMS is an ideal choice for critical environments that require high levels of protection and comfort.

The Manufacturing Process Of SMS Nonwoven Fabric

Polypropylene granules are melted and extruded to form a continuous filament. After this step is completed, the filament is laid on a conveyor belt to form a web of fibers. This web is bonded with the use of heat and pressure to create the fabric.

In this step, polypropylene granules are melted and extruded to form microfibres. These microfibers are then blown onto the spun bond layer to create a fine and dense layer to provide filtration and barrier capabilities.

In the last step, the final layer of SMS nonwoven fabric is passed through rollers to bond all the layers to improve its overall strength and durability. Once again, the fabric undergoes heating to arrive at its final form. The resulting fabric is then cut and prepared for different applications.

Are Smms More Effective Than Sms?

The SMS fabric which means Spunbond-Meltblown-Spunbond fabric is primarily utilized in the production of medical protective clothing, masks, and all other associated products owing to its barrier properties in addition to breathability. On the other hand, SMMS fabric has higher filtration efficiency and also liquid repellency compared to SMS fabrics. However, the overall functionality and its effectiveness will only be determined by the raw material used, the way they are processed, and the task it is going to be used for.

Spunbond Polypropylene

Spunbond Polypropylene: This is a non-woven fabric that is made from polypropylene fibers the process involves spinning the fibers and then using heat and pressure is applied on the surface. On account of its great strength, durability as well as water repellent features it is widely used with a variety of applications including medical protective wear, industrial canopies, and agriculture protective covers. Also, spunbond polypropylene has low density; it is also non-irritant and allows for ventilation that makes it possible to wear or use in different situations.

Meltblown Polypropylene

Meltblown polypropylene is one type of nonwoven fabric that is produced from micro-fibers which are spread and bonded in the process called melt-blowing. It is mostly applied in filtration systems, including face masks and air filters because of its effectiveness in trapping small particles. Meltblown polypropylene is fine and porous which is non-absorbent to water and gases and therefore suitable for use in many different fields.

What Is The Rating Of Protective Materials And Ppe?

Protective materials and personal protective equipment (PPE) are typically rated based on their effectiveness in protecting against various hazards. Ratings can vary depending on the specific type of PPE and the standards used to assess their performance. Some common ratings for PPE include:

  • ASTM (American Society for Testing and Materials) ratings - ASTM ratings are commonly used for materials such as gloves, gowns, and masks to indicate their level of protection against chemicals, fluids, or other substances.
  • ANSI (American National Standards Institute) ratings - ANSI ratings are often used for safety eyewear, helmets, and other protective gear.
  • NIOSH (National Institute for Occupational Safety and Health) ratings - NIOSH ratings are commonly used for respiratory protection equipment such as respirators to indicate their level of protection against airborne contaminants.
