Hh

Hand
How the carpet feels to the touch. Factors determining how the carpet feels include weight, stiffness, fiber type, denier, density and backing.

Hank
Term reffering to a skein of yarn.

Heather
A subtle multicolored effect produced by commingling yarns or spinning blended fibers of different colors together.

Heatsetting
Process for stabilization and setting a memory of twist in plied yarns. Conventional autoclave treats skeins with pressurized steam, usually at temps ranging 240° - 300°F, in a batch operation. Some machines employ a continuous dry heatsetting method, this is used most commonly for spun yarn heatsetting.

Heavy traffic
Term refers to 200 to 2000 traffics per day. Could also include some directional, nondirectional and rolling traffic, as well as tracked-in dirt.

Heddle
A frame of vertical cords or wires (like needles) through which warp yarns are threaded. The heddle is raised and lowered to interlace face yarns.

Hexamethylenediamine
A petrochemical compound with a chain of six carbon atoms which is reacted with adipic acid to make Type 6,6 nylon. It is a petrochemical.

Hexapod drum test
A rotating drum used as an instrument to test pile floor coverings. Carpet samples are placed in this rotating drum with a polyurethane studded metal ball to simulate the physical effects of traffic. This accelerated test provides a specific rating of the ability of the carpet to withstand crushing and matting.

Hollow filament fibers
Refers to filaments with interior voids. Hollow core fibers improve the soil-hiding ability of nylon by diffusing light passing through the fiber. Hollow filament fibers should be at least 89% solid polymer so that the interior voids do not weaken the fiber and cause it to fray under heavy wear.

Humidity
The measure of moisture in the atmosphere.

Hybrid carpet
A carpet in which two or more different yarn types are combined in the carpet construction.
