Flow Chart of Compact Yarn

Flow Chart of Compact Yarn

Compact Yarn is made by cotton fiber. The compact spinning is a process where a fiber strand drawn by drafting system is condensed before twisting it. The compact yarn is produced with maximum strength and Breaking elongation. Compact yarn reduced hairiness due to additional condensing zone in the drafting system. That’s why there high capital cost in compact spinning. But it eliminates using wax in the winding.

The flow of compact yarn is followed by the following steps

Mixing=>Blow-room=>Carding=>Pre drawing=>Lap forming=>Combing=>Post Drawing=>Roving=>Compact spinning=>Winding (Auto coner)

Introduce with High Volume Instrument

Introduce with High Volume Instrument (HVI)

Advanced fiber testing system high volume instrument is used to determine fiber properties in bale management system. It is fiber classing system. HVI is used to determine fiber length, strength, maturity, micronaire and other properties of the cotton fiber. HVI test report helps to law down the same properties bale before mixing. Mixing is a very important process for spinning.

Introduce with High Volume Instrument

Tests by HVI

  1. Micronaire (Mic)
  2. UHML (Upper half Mean length)
  3. UI (Uniformity index)
  4. SFI (Short Fiber Index)
  5. Fiber strength in g/tex
  6. Elongation
  7. Moisture content
  8. Color (Reflectance Rd, Yellowness +b)
  9. Color grade(USDA upland, Pima or regional customized color chart)
  10. Trash (% Area, trash count) & trash Grade (USDA)
  11. SCI (Spinning consistency Index)

Micronaire (Mic)

The parameter is describing the cotton fiber fineness. Micronaire Ratings: below 3.0= very fine 3.1-3.9 =fine 4.0-4.9 =average 5.0-5.9 = course over 6.0 =very coarse
Upper Half Mean Length (UHML)
Upper Half Mean Length means length by weight of the longer 50% of fibers.

Uniformity Index (UI)

Uniformity Index= length uniformity of the fibers. Uniformity index= ML. 100/UHML Classification of the length uniformity: very low-> below 76 low->77-79 average-> 80-82 high->83-85 very high ->above 86

Strength

Breaking force of the fiber bundle divided by fiber fineness Assessment of the fiber strength in gram per tex <gf/tex> (without long staple) below 21= very low 22 to 24 = low 25 to 27= average 28 to 30=high over 30= very high

Short fiber index (SFI)

Short fiber index =percentage of fibers shorter than 1/2 inch or 12.7 mm

Spinning consistency index (SCI)

A coefficient is calculated by means of various quality characteristics by a multiple regression analysis. The SCI used is calculated with the original formula provided by USTER. The main benefit of the SCI is a simplified selection of bales for a predetermined blend of fibers as well as the long-term check of the say material blend.

Color

Reflectance (Rd) – reflectance of the fibers, higher Rd values mean a higher color grade. Yellowness (+b)-Yellowness of the fibers (Nickerson/Hunter scale)

Trash

Trash Area (Tr Area)
•    Area of the sample covered with trash particles.
•    Trash Cnt (Tr cnt)
•    A number of trash particles in a sample.

Ambient conditions

The standard temperate atmosphere for textile testing according to ISO 139
•    Temperature: -20+_(plus minus) 2 degree C -68+_ 4 degree F
•    Relative Humidity(RH):65+_4%

Objects of Fabric Spreading

Fabric spreading is a process by which fabric plies are spreaded in order to obtain required length and width according to marker dimension. One of the main objects of fabric spreading is cut garments in bulk and saving in fabric.

Description of fabric spreading

Spreading means the smooth laying out of the fabric in plies or layer of specified length. The cutting marker is layed on the most top layers. The maximum width of the cutting marker is constrained by the usable width of the fabric. No of lay should not be more than three hundreds during spreading of fabric. But it can vary according to the thickness of fabric. It also depends on the height of the knife.

The spread of fabric can be of basic two types

  1. Flat spread
  2. Stepped spread

Objects of fabric spreading

  • To place the number of plies of fabric to the length of the marker plan correctly aligned as to length and width and without tension.
  • To cut garments in bulk and saving in fabric.
  • To save cutting time by cutting many plies at a time.
  • To ensure every ply plain and flat.
  • To reduce manufacturing cost by cutting in proper way by ensuring proper fabric spreading.

Factors considered for ply height determination

Thickness of the fabric

When the thickness of fabric is more than the no of ply will be less and if the thickness of fabric is less than the no of ply will be more.

Cutting knife length

Lay height will be 70% of the length of cutting knife.

Volume of production

If it is bulk production then no of ply is more end hence height of lay is more.

Nature of fabric

Ply height will not be same for both cotton and synthetic fabric or any others types of fabrics. In case of same no of ply, cotton can be cut but synthetic fabric can not be cut.

Basic Operation in Blow Room

Blow Room: There are some methods of opening the mass of fibres into small tufts before further processing. This process of opening & clean is knows as blow room process. Blow room consists of a number of m/c degree 40% to 70% trash is removed in this section.

basic operation in blow room

Blow Room

Objects of Blow Room Process

  1. To open the compressed layer of bale of cotton or any staple fibers with minimum damage to the fibers.
  2. To remove the impurities like sand, seed, bits, neps & short fibers present in the cotton with minimum loss of lint by opening & blending.
  3. To effect a through blending with minimum neps formation.
  4. To convert the mass of cotton fibres into a uniform thick sheet of cotton both longitudinally & transversely &fed as it in the case of chute feed system or wound in the form of a compactly built lap with minimum lap rejection.
  5. Intensive de-dusting of cotton fibres to extract micro-dust in order to improve the working of opened spinning m/c.
  6. Fibre recovery from the waste produced by the various processes the conversion of fibre to yarn in order to reduce the consumption of raw material.

Basic Operation in Blow Room

  1. Opening

    1. Opening is the first operation required carried out to the stage of flocks in the blow room & to the stage individual fibres in the card flock weight can be reduced to about 0.1mg in the room.
  1. Cleaning

    1. The blow room cannot eliminate all or even almost all of the foreign matter in the raw material.
    2. A blow room installation removes approximately 40% to 70% of the impurities.
    3. The result is dependent on raw material on the m/c s & on environment.
  1. Dust removal

    1. Dust removal is not easy operation since the dust particles are completely enclosed in the flocks & hence are back during suction.
    2. The suction units remove dust 64 dust removal will more intensive the smaller the flocks.
  1. Blending

    1. Fibers can be blending at various stages of the process. These possibilities should always be exploited.
    2. The start of the process is one of most important stages for blending.
    3. Intensive blending in a suitable blending m/c must be carried out after separate flock extraction from individual bales of layout.
    4. This blending operation must collect the sequentially arriving bunches of fibers from individual bales & mixes them thoroughly.
  1. Even feed of material of the card

    1. Finally the blow room must ensure that raw material is evenly delivered to the cards. Previously, this was carried out by means of precisely weighed laps from the scutcher, but automatic flock feeding installations are increasingly being used.
    2. While in the introductory phase such installations were subject to problem regarding evenness of flock deliver, today they generally operate well or at least adequately.
