    This presentation summarizes various fiber properties that are essential to know for different end uses and product quality. It discusses properties such as resiliency, flammability, moisture regain, chemical reactivity, abrasion resistance, tenacity, flexibility, uniformity, cohesiveness, morphology, physical shape, luster, and moisture regain. Tenacity refers to fiber strength, which is important for durability. Flexibility allows fabrics to permit freedom of movement. Uniformity ensures even yarns and consistent performance. Cohesiveness and morphology impact fiber processing. Properties like shape, luster, resiliency and moisture regain also influence end use and quality.

    Short discussion on

    Fiber properties.
    What Is fiber properties?

    Fiber properties are essential thing to know


    for various end uses and the products made
    from it qualify on the basis of certain
    parameters.
    The various properties are-
    Resiliency.

    Flammability Moisture regain.

    Chemical Electrical conductivity.


    reactivity.

    Abrasion
    resistance.
    Tenacity

    The strength of textile fibers is referred to


    Tenacity is, directly related to the length
    as their tenacity. It is determined by
    of the polymers, degree of
    measuring the force required to rupture
    polymerization, strength in dry and wet
    or break the fiber. Sufficient tenacity is
    conditions, and types of inter- polymer
    required to withstand the mechanical and
    forces of attraction formed between the
    chemical processing as well as make
    polymers.
    textile products which are durable.
    Flexibility

    Fibers should be flexible or pliable in


    order to be made into yarns and
    thereafter into fabrics that permit
    freedom of movement. Certain end
    uses require greater flexibility,
    e.g., automobile seat belts.
    Uniformity of fibers
    towards its length, ensure
    production of even yarns
    which can then form fabrics
    of uniform appearance and
    consistent performance.
    Cohesiveness or spinning quality-

    * It is the ability of the


    fiber to stick togeiner
    properly during yarn * Natural fibers have
    manufacturing inherent irregularities in
    processes. their longitudinal or cross
    sections which permit them
    to adhere to each other
    during fiber arranging.
    Morphology-

    It is the study of
    physical shape and form
    oi a fiber. It includes
    microscopic structure
    like longitudinal and
    cross sections. These
    also include fiber length,
    fineness, crimp, color
    and luster.
    Physical shape-
    shape of a fiber
    include, its
    longitudinal
    sections, cross
    section, surface
    contour,
    irregularities and
    average length.
    Luster-
    It refers to the sheen or gloss that a iper possesses.
    It is directly proportional to the amount of light
    reflected by a fiber.

    Cross sectional shape Degree of luster


    round High
    Ireegular Low
    Kidney shaped Low
    Oval High
    Trilobal High
    octagonal low
    Resiliency

    Resiliency refers to the ability of a fiber to come back to


    its original position after being creased or folded.
    Resilient fibers recover quickly from wrinkling or
    creasing. Good elastic recovery usually indicates good
    resiliency. This property is described qualitatively and
    ranges from excellent to poor. Excellent resiliency is
    exhibited by polyester, wool and nylon fibers. Flax,
    rayon and cotton, on the other hand, have a low
    resiliency.
    Moisture regain

    The ability of a bone dry fiber to absorb moisture is called moisture regain.
    Measurements are done under standard testing conditions (70°+ 2F and 65%
    ±2% relative humidity). Saturation regain is the moisture regain of a
    material at 95-100% relative humidity. Both regain and content are
    expressed as a percentage.
    •Moisture regain= wt. of water in a material oven dry wt. × 100
    •Moisture content= wt. of water in a material total wt. × 100
