Crimp
The waviness or three-dimensional configuration of a fiber, contributing to its elasticity and bulk.
Twist
The number of turns per unit length along a yarn or fiber, affecting the strength, texture, and appearance of the yarn and resulting fabric.
Yarn Count
A numerical expression that indicates the fineness or coarseness of a yarn, which can be measured in various systems, such as Ne (English count) or Nm (metric count).
Colorfastness
The resistance of a textile's color to fading or running, influenced by exposure to light, perspiration, washing, and other environmental factors.
Drape
A term used to describe the way a fabric hangs and conforms to the contours of the body or an object.
Fiber Fineness
A measure of the diameter of individual fibers, affecting the softness and quality of the textile.
Fabric Hand
The feel or quality perceived when a fabric is touched, influenced by fiber content, construction, and finishing processes.
Nonwoven Fabric
Textiles made by bonding or felting fibers together without weaving or knitting, often resulting in a fabric with a random fiber orientation.
Breathability
The ability of a fabric to allow perspiration and air to pass through it, contributing to thermal comfort.
Loft
The height and fluffiness of a fiber or fabric, which contributes to its insulating properties by trapping air.
Biodegradability
The capacity of a fiber or textile to decompose naturally by biological means, being an aspect of environmental sustainability.
Filament
A long continuous fiber that can be spun into yarn or directly used in the making of fabrics, as seen in silk and synthetic fibers like polyester.
Hydrophilic Fibers
Fibers that have a strong affinity for water, which makes them absorbent but also prone to prolonged drying times.
Hydrophobic Fibers
Fibers that repel water and are not easily wetted, often leading to quick drying properties.
Anti-Microbial Properties
The ability of a textile to resist or inhibit the growth of microorganisms, often through chemical treatment or the intrinsic properties of the fibers.
Moisture Regain
The amount of moisture a textile can absorb from the air under standard conditions, expressed as a percentage of the dry fiber weight.
GSM (Grams per Square Meter)
A metric measurement of the weight of a fabric, which is the grams of fabric per one square meter area, denoting its density and thickness.
Felting
The process of interlocking wool fibers into a dense material by the application of heat, moisture, and mechanical action.
Shrinkage
The reduction in size of a textile product after laundering or dry-cleaning, often caused by fiber relaxation or structural changes.
Tensile Strength
The maximum stress that a textile fiber can withstand while being stretched or pulled before breaking.
Pilling
The formation of small, fuzzy balls on the surface of a fabric caused by abrasion during wear or washing.
Warp and Weft
Warp are the longitudinal threads attached to the frame of a loom, and weft are the cross threads weaved into the warp.
Thermal Conductivity
A measure of a textile's ability to conduct heat.
Denier
A unit of measurement that describes the linear mass density of fibers, specifically the mass in grams per 9000 meters of the fiber.
Abrasion Resistance
The ability of a textile to withstand surface wear from rubbing.
Elongation
The degree to which a textile fiber can be stretched or extended before breaking, typically expressed as a percentage of its original length.
Staple Fibers
Short lengths of fibers, either natural or cut from manufactured filaments, which must be spun together to make yarn.
Wicking
The ability of a fabric to transport moisture away from the body to the fabric's outer surface where it can evaporate.
Flammability
The ability of a textile to support combustion, an important safety consideration in textile selection and use.
