Fabric Performance Concepts & Fibers Properties

Fabric Performance

The ability of a textile product to serve its end use

Fiber Properties

Relate to each fabric performance concept

PROPERTIES OF DURABILITY

PROPERTIES OF DURABILITY

Abrasion Resistance

The ability of a fabric to withstand rubbing without breaking

Pilling

Pilling is also caused by rubbing but with a different end result. The formation of tangled fibers on the surface of the fabric

Cohesiveness

The ability of fibers to cling together. Important for yarn spinning. Usually provided by crimp

Feltability

the ability of a fiber to matte together to form a fabric

Elongation

the degree to which a fiber may be stretched without breaking; the amount it gives. Growth can be a problem

Elasticity

The ability of a fiber to stretch and recover. The ability of a fiber to return to its original size and shape after being stretched

Dimensional Stability (Shrinkage)

The ability of a fiber to retain a given size and shape through use and care

Tenacity

(Strength) The ability of a fabric to resist stress

Tensile Strength

The ability of a fabric/fiber to withstand a pulling force (breaking point)

Tearing Strength

The measurement of strength that it takes to continue a tear (once fabric/fiber has been broken)

PROPERTIES OF COMFORT

PROPERTIES OF COMFORT

Absorbency

The ability of a fiber to take up moisture from the body or from the enviroment

Hydrophilic

fibers absorb water easily

Hydrophobic

fibers absorb little or no water

Hygroscopic

the ability of a fiber to absorb moisture (water vapor) from the air without feeling damp

Wicking

the ability of a fiber/fabric to pass moisture to the surface for evaporation

Electrical

Conductivity: the ability of a fiber/fabric to transfer electrical charges
Retention: the ability of a fiber/fabric to build up electrical charges causing fabric to cling to the body

Thermal

Conductivity: the ability of a fiber/fabric to transmit heat from the body
Retention: the ability of a fiber/fabric to hold heat next to the body

Allergic Potential

The ability of a fiber/fabric to cause some physical reaction such as skin irritation or watery eyes

Specific Gravity

The ratio of the weight of a given volume of fiber to an equal weight of water. A lightweight fiber enables a fabric to be warm without being heavy

Density

The compactness or openness of a fabric. Lightweight fibers can be made into thick fabrics that are more comfortable to wear than heavyweight fabric

Air Permeability

The degree of porosity in a fabric or the ease with which air passes trough it

Cover

the ability of a fiber to occupy an area

PROPERTIES OF CARE

treatments that are required to maintain the original look of a textile product, wear, cleaning, and storage

Resiliency

The ability of a fiber/fabric to return to it original shape after bending, compressing, twisting or crushing. (Relates to wrinkle recovery)

Oliophilic vs Oleophobic

Fibers have an affinity to oil based stains. Oil-loving (hold oily stains) or oil-heating

Chemical Reactivity

The affect of acids, alkali, oxidizing agents, solvents, enzymes, bleaches or other cleaning agents

ENVIROMENTAL EFFECTS

...

Biological resistance

to moths, mildew, sliverfish, ect

Sunlight resistance

the ability to withstand degradation from direct sunlight

Aging resistance

the ability to maintain it orginial qualities over time

THERMOPLACITY

the ability too soften, melt or shrink when exposed to heat. This aids in the production of permanent-pleates, creases, or shapes. Becomes plastic and will retain a predetermined shape when cooled

Heat tolerance

the ability to withstand heat when subjected to cleaning, drying, and ironing

Heat sensitivity

the exact temperature at which a fiber will melt, soften or shrink when subjected to heat

PROPERTIES OF APPERRANCE

the maintenance of a fabrics attractiveness to remain aesthetically acceptable and serviceable

shape & length of fiber

influences apperance, care and comfort

color

the first aesthetic property noticed in a textile product

colorfastness

the ability of a fiber/fabric to retain color when exposed to certain environmental or chemical conditions

dye affinity

the individual fibers receptivity to coloration by a particular dyestuff

luster

sheen created by light reflective

translucence

the ability to pass light through a fiber, yarn or fabric

drape

the manner in which a fabric falls or hangs. indicative of flexibility

texture

the 3 dimensional nature of the fiber, yarns or fabric surface

body

the stiffness, firmness, or looseness of a fabric

loft

the ability to spring back to original thickness after being compressed

hand

the adjective used to describe the way a fiber feel to the touch (soft, smooth, crisp, dry, textured, ect.)

PROPERTIES OF SAFETY

the way a fiber burns for fiber identification and safety

flammability

the ability of a fiber to ignite and burn

inflammable

ignites and burns readily, with a bright orange glow. smells like burning paper or wood. does not easily extinguish

flame retardant

fabrics which will burn but self extinguish when removed from flame. smells like burning hair

flame resistant

fabrics which will burn and melt. often will self extinguish when removed from flame. smells like burning plastic

nonflammable or flameproof

fiber/fabric will not burn
