T

Tacky
Slightly sticky.

Tear resistance
The force required to begin or to continue a tear in a fabric under specific conditions. (The tear resistance of a nonwoven fabric is usually measured by the Trapezoidal Tear Test).

Tenacity
A measure of the strength of a fibre. The force exerted per unit linear density when tensile stress is applied. Expressed as Newton per tex. Newtons are units of force. Previously expressed as grams force per denier.

Tensile strength
1) In general, the strength shown by a specimen subjected to tension as distinct from shearing stress, bending or twisting momentum.

2) Specifically the maximum tensile stress expressed in force per unit cross sectional area of the unstrained specimen e.g. Newtons per square millimetre.

Tex
A metric measure of the mass per unit length of a fibre. It is numerically equal to the mass in grams of one kilometre of the material. It is also equal to the denier divided by 9.

Texture
A term describing the surface effect of a fabric such as dull, lustrous, woolly, stiff, soft, fine, coarse, open, or close; the structural quality of a fabric.

Texturing
A process for imparting crimp, crepe and bulk to fibres yarns and fabrics.

Thermobonding
A method of bonding a web of fibres in which a heat or ultrasonic treatment, with or without pressure, is used to activate a heat-sensitive material, which may be in the form of homofil fibres, bicomponent fibres, or as all or part of the web. The bonding may be applied all over (through or area bonding) or restricted to predetermined discrete sites (point bonding).

Thermoplastic
Polymeric materials that have a melting temperature and can flow or be formed into desired shapes on the application of heat at or below the melting point.

Thermoset
Polymeric materials that become intractably hardened by exposure to heat and/or catalyst action.

Thickness
The dimension of a sheet or lamina measured perpendicular to the plane of the sheet under a specific pressure.

Thread
A spun-out filament. A thin structure of twisted yarns.

Torque
The moment of a system of forces tending to cause rotation.

Toughness
Ability to absorb work. Commonly measured as the area under the stress/strain curve. The opposite of brittleness.

Tow
A bundle of continuous filaments. The form of most manmade filaments before being cut into staple.

Tufting
Make insertions of clumps of fibres into depressions in the base fabric to form a 3D structure with the tufts of fibres oriented in the vertical direction.

Turret
Cylindrical type of rewinder.
