COATING & LAMINATINGDEFINITION
Coating: A textile fabric on which there has been formed
in situ, on one or both surfaces, a layer or layers of
adherent coating material (for decorative or functional
goals).
Lamination: A material composed of two of more layers,
at least one of which is a textile fabric, bonded closely
together by means of an added adhesive, or by the
adhesive properties of one or more of the component
layers (for decorative or functional goals).
1. Mechanical properties: drape ability, dimensional properties, elongation,
tear and tensile strength.
2. Chemical properties: barrier properties to dust, filtration, water, chemicals
etc.
3. Other: fabric abrasion.
Combination determines fabric handle.
With coating you combine two materials which leads to new properties.
Not breathable. However microporous breathable coatings can be
engineered.
With lamination, the two materials can retain their individual properties.
Breathable.
COATING
Post treatment: curing.
material is dried out by
placing it an oven (if needed)
and chemical bonds are
formed between the fabric and
coating material.
, STEP 1: BASE FABRIC
Fabrics:
- Cotton
- Polyester
- Polyamide
- Polyethylene
- Acrylic
- Glass fibers
Yarns:
- Fiber
- Filament (BCF)
Spun fibers during coating the coating paste tends to rub against the fibers
causing the fibers to stand out. Therefor in case direct coating (a type of coating)
filament yarn fabrics are preferred.
Construction: influences drape, handle, tear strength, stiffness, etc.
- Plain
- Twill
- Basket
- Knitted
- Nonwovens
A very open fabric when treated with viscous coating paste show high degree of
stiffness due to high penetration or vice versa can happen. With a tightly woven
fabric and a very viscous paste, the penetration is poor.

STEP 2: POLYMER / SOLVENT / ADDITIVES
p. 35-38
Coatings: Types of coating
- PVC (poly vinyl chloride) - Solvent based
- PVDC (polyvinylidene chloride) Polymer + additives + solvent
- PU (polyurethane) (Toulene, isobutylalcohol)
- EVA (ethylene vinyl acetate) Flammable, good wetting and
- PTFE (polytetrafluoroethylene) spreading
- PVA (polyvinylacetate) - Water based
Polymer + additives + water
Cheap, dries slowly
- Plasticized based
PVC + additives + placticizer
Makes PVC flexible. Flame
