UV RESISTANCE
The ability to retain strength or other properties upon exposure to ultraviolet light.
UV ABSORBERS
Various chemicals or polymers added to the product that absorb the ultraviolet light or otherwise make the material resistant to ultraviolet degradation.
UNIDIRECTIONAL FABRIC
A fabric having strength mostly in one direction, generally the machine direction. References for this information: Inda
UNBONDED
A fiberfill material that has not had any form of bonding treatment. References for this information: Inda
ULTRASONIC BONDING
The use of high frequency sound to generate localized heat through vibration and thereby cause thermoplastic fibers to bond to one another. See also SONIC BONDING. References for this information:…
UNIDIRECTIONAL
Performing best in only one direction; generally applied to nonwovens in which the fabric strength is highly oriented in the direction of web travel through the forming process. References for…
TUFTING
Make insertions of clumps of fibers into depressions in the base fabric to form a 3D structure with the tufts of fibers oriented in the vertical direction. References for this…
TRICOMPONENT FIBER
A fiber that is made from three polymers that are physically or chemically different. References for this information: Inda
TOW
A bundle of continuous filaments. The form of most manmade filaments before being cut into staple. References for this information: Inda Edana
TOUGHNESS
Ability to absorb work. Commonly measured as the area under the stress/strain curve. The opposite of brittleness. References for this information: Inda Edana
