1
Q
Carpet Types
A
- Broadloom or sheet (12’ wide goods)
- Carpet Tiles (indiv squares)
- Rugs (soft floor covering)
2
Q
Carpet Construction
A
- Tufting (big stitch into back with latex)
- Fusion Bonding (yarn direct into liquid vinyl)
- Needle Punching (pushed and pulled through barbed needles, secondary backing too)
- Weaving (interlace warp (lengthwise) and weft (runs crosswise)
- Knitted (pile and backing in one operation)
3
Q
Gauge
A
- measure of the spacing of the tufting needles, center to center across the width. 1/8 gauge, needles are 1/8” apart, produces 8 yarn ends per inch

Q
Stitches
A
number of ends sewn by needles down the lenght of the carpet
4
Q
Pile Height
A
lenght of a tuft from backing surface to the tip of the tuft. Measured in a fraction of an inch.

- random tip shear/random shear (cut and loops of all the same height)
- shag (long pile and loose construction)

Q
Carpet Appearance & Durability
A
- face weight - weight of pile yarn
- total weight - finished weight
- pile density - weight of pile yarn
- yarn count - thickness of yarn
- delamination - separation of backing
- colorfastness - resistance to fading
- static generation - generation of
- tuft bind - force required to pull out tuft
- wear resistance - abrasion resistance
- appearance retention - how looks in heavy traffic
6
Q
Carpet Backing
A
- backing on which yarn is tufted, bonded or woven
- primary - locks fibers in place
- secondary - bonded
6
Q
Broadloom Carpet Installation
A
Stretched in - streched over cushion and attached at perimete
- Direct glued - glued to floor
- double glue down - cushion adhered to floor and carpet glued to cushion
- self-stick - flexible adhesive layer applied to carpet backing and covered with a protective plastic film
