    Srishti Sanyal
    This document provides an overview of knitted fabrics, including the different types of knits, yarns used, and basic knitting stitches. It discusses weft and warp knitting processes, with warp knitting having vertical loops produced along the length of fabric. Specific warp knits covered are tricot and raschel, with tricot being soft and wrinkle-resistant and often used for lingerie, while raschel has more texture and is used for items like carpets and blankets. Basic knitting stitches like plain, tuck, and miss are also explained.

    Topic-I

    • Introduction to knitting
    • Types of yarn used in Knitting
    • Warp knitting
    • Weft knitting

    Introduction to Knitting

    • The term knitting describes the


    technique of constructing
    textile structures by forming a
    continuous length into
    vertically intermeshed loops.
    • Knitted fabric consists of
    consecutive loops, called
    stitches.
    • It can be done using machine
    or by hand.
    4
    Yarn Requirements for
    Knitting
    • Yarn count and machine gauge
    • Yarn Twist
    • Uniformity
    • Coefficient of friction
    • Flexural Rigidity
    • Tenacity and Elongation
    • Yarn hairiness
    • Elasticity
    • Moisture content
    • Yarn winding

    Warp Knitting
    In a warp knitting structure each loop in the vertical direction is made from
    different thread.
    Weft Knitting
    In a weft knitting
    structure a horizontal
    row of loops can be
    made using one
    thread and the thread
    runs in the horizontal
    direction. Most of the
    knitting fabric are
    produced by weft
    knitting
    DIFFERENCE
    Warp knitting Weft knitting

    The loops are produced to the length of The loops are produced to the width of
    fabric . fabric.

    Elastic to the length Elastic to the width

    Elasticity less than weft knitting Elasticity higher than warp knitting

    Shrinkage properties is less Shrinkage properties is higher

    At least one yarn is required for each Any number of yarn


    needle

    Yarn are supplied from beam Yarn are supplied from cone

    Any design is done easily All types of design is complex.


    Basic Stitches

    Knit/Plain
    Tuck Stitch
    Stitch

    Float/ Miss
    Stitch
    PLAIN STITCH

    PLAIN STITCH IS THE BASIC KNITTING STITCH.IT IS ALSO CALLED


    THE KNIT STITCH.
    Knit stitch is formed when the needle carries out a complete stroke,
    reaching the maximum height on the looping plane.
    TUCK STITCH

    A TUCK STITCH IS FORMED WHEN A


    KNITTING NEEDLE HOLDS ITS OLD
    LOOP AND THEN RECEIVE NEW
    YARN, TWO LOOPS WILL THEN
    COLLECT IN ONE NEEDLE HOOK.
     Tuck stitch
    A tuck stitch is formed when a knitting needle holds its old loop and then
    receives a new yarn. Two loops then collect in the needle hook. The
    previously formed knitted loop is called the held loop and the loop which
    joins it is a tuck loop.

    The resultant stitch is elongated. Tuck stitches appear on the back of a


    fabric and may be recognised as an inverted V, sometime elongated for
    two or more courses, depending on how many times the stitched was
    tucked.

    The tuck stitch is used in knitted fabric to create design effects in colour,
    raised surface texture, or a hole or eyelet effect
    MISS STITCH

    A MISS IS CREATED WHEN ONE OR


    MORE KNITTING NEEDLES ARE
    DEACTIVATED AND DO NOT MOVE
    TO ACCEPT YARN. YARN MERELY
    PASSED BY NO STICH IS FORMED.
    Knit, tuck and miss stitches can be used in any of the four
    fabric types – single jersey, rib, purl or interlock – to produce
    a wide range of structural effects. 
    WARP KNITTING

    • Warp knitted fabric is produced from a set of warp yarn. It is parallel knitted to
    each other down the length of the fabric.

    • More resistant to laddering than weft knits.


    Warp Knitting
    • Second major category of knit fabrics
    • Characterized by vertical loops
    • More resistant to laddering than weft knits
    • Usually done on flat knitting machine
    • Two main types of warp knitting machine
    1. Tricot
    2. Rachel
    Tricot Knits

    • The right side of the fabric has fine lengthwise ribs while the reverse has
    crosswise ribs.

    • A soft and 'drapey' texture with some lengthwise stretch and almost no
    crosswise stretch.

    • Tricot fabric is soft, wrinkle resistant.

    • Tricot is very common fabric for making lingerie.


    TRICOT KNIT
    • Good elasticity
    • Best of warp knits
    • Inexpensive and quick to produce
    • Good air and water permeability
    • Soft
    • Crease resistant
    • Good drapeability
    End Uses of TRICOT
    • Lingerie
    • Nightwear
    • Dresses
    • Used as a backing fabric in multi-component
    structures
    RASCHEL KNIT
    • Similar to Tricot Knits
    • Greater diversity in design
    • More texture
    • Open spaces
    • Made from heavier yarns
    End uses of Raschel
    • Fine laces and nets
    • Heavy carpets
    • Thermal underwear with a waffle effect
    • Power-net fabrics for swimsuits and foundations
    • Heavy blankets
