Carpet
Definition and Types of Fibers
- Definition: a general designation for fabric used as floor covering, providing softness, resilience, and warmth.
- Types of fibers:
- Natural fibers: wool, sisal, jute, cotton, maize, coir
- Synthetic fibers: nylon, acrylic, modacrylic, polyester, polypropylene olefins
Parts of a Carpet
- Face: the upright ends of yarn, forming the wearing surface
- Primary backing: the canvas on which yarns are woven
- Latex adhesive: a synthetic rubber compound that glues the roots of the yarn to the primary backing
- Secondary backing: a cotton mesh cloth bonded to the primary backing
Methods of Manufacturing Carpets

Factors to Consider in Carpet Construction
- Pile density: the weight of pile yarn in a given volume of carpet face
- Widthwise density measurement:
- Gauge: the distance between the needles
- Pitch: the number of ends in a 27-inch width of carpet
- Lengthwise density measurement:
- Stitch rate: the number of times per inch a stitch occurs
- Pile height: the length of the tuft from the primary backing to the tip

Carpet Cushion or Underlay
- Definition: a foundation that increases wearability, provides added insulation, and deadens sound
- Types of cushions:
- Fiber cushions: made by needlepunching natural or synthetic fibers
- Sponge rubber cushions: made from flat sponge, ripple sponge, or reinforced foam rubber### Polyurethane Foam Cushion
- Three types of polyurethane foam cushion: bonded, modified prime, and densified prime urethane foam.
- These types have similar chemical compositions but differ in cellular structure, affecting performance.
- Bonded foam is manufactured from scraps of foam bonded together through adhesive and heat fusion process.
- Modified prime foam is manufactured in a continuous sheet and may contain fillers.
- Densified foam is denser than modified prime foam and highly resistant to bottoming out.
Installation Methods
- Tackless Stripping (or Stretch-In Installation): traditional installation method for residential applications and commercial woven wool carpets.
- Glue-down Method: used with bonded carpet, high density foam rubber is used as the secondary backing and cemented directly to the floor.
- Direct Glue-down: most common method of commercial installation, economical and practical, carpet is glued directly to the floor without a cushion.
- Double Glue-down: combines underfoot comfort of stretch-in installation with stability of direct glue-down, carpet cushion is adhered to the floor and carpet is glued to the cushion.
- Self-stick: latest development in carpet installation techniques, flexible adhesive layer is applied to carpet backing, labor and time are eliminated.
Rugs
- Definition: a single piece of compact, woven, knitted, or tufted fabric with borders, intended as a floor covering.
- Manufactured from natural or man-made fibers, produced in various lengths, widths, and shapes.
- Each rug is a separate unit, meant to cover only a portion of the floor area, not the whole floor.
