Fabric that has received no finish (also known as loom state, untreated).
H
Heat cleaning
Thermal treatment conducted in a static oven to remove the organic materials applied to glass fabrics.
I
Inspection machine

K
Kinky filling
Filling with protruding loops on the surface of a fabric.
Knitted scrim
Flat structures in which both warp and weft yarns are regularly, widely spaced and fixed by means of a warp knitting process.
L
Laid scrim
Textile structure in which the weft and warp yarns are linked together by an adhesive.
Laminated fabric
A multi-layer fabric, in which the successive layers are fixed by bonding or impregnation on one or more surfaces.
Linear density
The mass per unit length of the yarn, with or without size, expressed in the tex system (g.km-1) (according to ISO/DIS 13922).
Loss on ignition (LOI)
