 Type 5 & 6 Fabric Comparison 


Three types of fabric are generally used for Type 5 & 6 coveralls. For a detailled technical comparison download the Lakeland Type 5 & 6 Selection Guide.

Fabric Type    SMS Polypropylene Microporous Film Laminate Flashspun Polyethylene
Structure

SMS = “Spunbond – Meltblown – Spunbond”

This describes the fabric structure: one or more layers of “meltblown” PP fibre sandwiched between two layers of standard spunbonded polypropylene. The meltblown fabric consists of fine discrete fibres which create effective dust filtration and liquid repellency. The outer spunbond layers provide structure and strength. Sometimes layers are bonded in different structures – eg: SMMS, SMSMS etc).

A microporous film (usually polyethylene) is laminated to a substrate of spunbonded Polypropylene.

Microporous films features a structure similar to a sponge – but on a microscopic scale. Millions of tiny cavities create “wormholes” - pathways so tortuous and tiny that dusts, most liquids and even air cannot easily pass through. These pathways however allow moisture vapour to “transmit” through… Moisture Vapour Transmission - sometimes described as a form of breathability 

Polyethylene mixed at high pressure with a solvent is blown into fine fibres, the solvent "flashing" off in the process - hence the name - and compressed into a dense sheet of bonded fibres. The density of the fabric means it features effective liquid repellency but low breathability compared with SMS

Weight  (generally) 50 to 55gsm  (generally) 60-65gsm 42gsm
Air Permeability 40 cubic feet / minute <0.5 cubic feet / minute approx 3 cubic feet per minute
Properties
  • SMS Polypropylene features high, true breathability so is the best option where comfort is paramount.
  • Liquid repellency and dust filtration is not as good as Microporous films however.
  • SMS products are generally not suitable for clean areas or where contamination of the area or product is an issue because they have a wholly fibrous structure... if damaged the tiny meltblown fibres may be released
  • Microporous films have excellent liquid repellency properties - superior to traditionally used flashspun polyethylene - as evidenced by their relative performance in protection against infectious agents and EN14126 testing.
  • Like flashspun PE however microporous films feature limited true breathability... although the excellent softness and drape along with high MVTR (Moisture Vapour Transmission Rate helps to maintain comfort
  • Liquid & dust repellency is less than microporous film but greater than SMS
  • bretahability is similar to microporous film when compared with the high breathability of SMS
Product Selection?

Select Safegard where comfort is paramaount and a liquid repellency is less critical

Select MicroMAX where liquid repellency is paramount or where 
protection against infectious agents is required

Not offered by Lakeland

Alternatives?

For an effective alternative try the MicroMAX NS Cool Suit... a composite garment featuring a MicroMAX NS coverall with a breathable blue Safegard back... combines the protection of MicroMAX with the breathable comfort of Safegard.
