What are washable webs
Washable webs refer to fabrics that have been manufactured from non-woven sources.
How are washable webs created
Webs of synthetic fibres are bonded together with heat or adhesives
What does this result in (washable webs)
A cheap fabric, one that is not as strong as a woven or knitted fabric
Characteristics (ww)
Easy to sew, crease-resistant, don’t fray and are stable to washing or dry-cleaning
Qualities of washable webs
They are light to heavy in weight and can be engineered for specific end-uses
THey do not fray
They are durable, abrasion resistant and highly absorbent –> gives them enhanced performance potential
End uses of washable webs
Apparel - interlinings, interfacings, clothing and glove insulation
Non-apparel - blankets, nappies
Specialised apparel - surgical equipment, masks, gowns
Army apparel - uniforms, parachutes
What is microfibre
Microfibre refers to synthetic fibres that measure less than one denier used to make non-woven, woven and knitted textiles
Common types of microfibre
Polyester, nylon, acrylic or rayon
Qualities of microfibres
Ultra-fine, lightweight, extremely high drapeability, washable and dry-cleanable, shrink-resistant,
can be woven tightly, so insulates well against wind, rain and cold
Microfibres can create waterproof and water resistant fabrics without the use of synthetic resin coatings as fine yarns are packed tightly together
End uses of microfibres
Apparel - hosiery, dresses, sportswear
Furnishings - curtains, draperies, sheets
What is Teflon Fabric Protector
A soil-resistant,fluoro chemical finish that forms an invisible shield around each fibre, protecting it from spills and stains.
What does Teflon do?
Gives a durable, long-lasting protection by forming a molecular shield. It is undetectable by sight, smell or touch and can be used on all fabrics.
What is the process? - Teflon
It is applied as the last step at the textile mill. The fabric is immersed in a a water bath containing Teflon, with excess squeezed out before travelling through an oven to dry and cure to set
What is PROBAN
PROBAN is used mainly on cotton and produces an invisible polymer inside the fibre. WHen it comes in contact with a flame a char is formed, no melting of after glow.
Where does treatment take place? - Proban
Proban is both a chemical and a quality-controlled technological process; treatment takes place at the finishing stage of cotton and cotton blended textile manufacture
What is the process? - Proban
The proban process involves chemical impregnation. Dying and curing with ammonia gas using Rhodia’s patented licensed technology is followed by oxidation and finally neutralisation.
How does PROBAN react to fire?
When fire comes into contact with Proban treated cotton the material chars rather than burns immediately insulating the wearer from the heat of the flame.
Qualities - proban
It is lightweight, resembles denim and provides the best balance between protection from heat while still allowing body heat to escape
Advantages + Disadvantages
Protection from burn injuries. Does nota lter cotton properties and no static electricity. Lasts forever but makes things heavier and more expensive.
End-use of PROBAN
Used for fire-fighter uniforms, racing drivers suits, curtains.
