What are the characteristics of yarn?

Rotor spun yarns are generally produced from short staple fibers….Different Types of Yarn and Their Properties.

Yarn types General yarn properties
High bulk yarns: Staple, Continuous filament Good covering power with light weight; good loftiness of fullness
Stretch yarns: Continuous filament High stretch ability; good handle and covering power

What should be the ideal properties of yarn?

Essential and Desirable Properties of Textile Fibres | Characteristics of Good Textile Fibre

  • Length and length variation. Length is an important parameter that determines the usefulness of a textile fibre.
  • Strength.
  • Uniformity.
  • Spinnability.
  • Fineness.
  • Resilience.
  • Capillarity and porosity.
  • Lustre.

Why is quality of yarn important?

Yarn density has a great influence on the appearance, handle, weight and mechanical properties of the fabric, so it is necessary to select a reasonable yarn density according to different uses. For example, outerwear fabrics in winter should be heavy, wear-resistant, insulated, and made of medium-Tex or high-Tex yarns.

How do you describe yarn?

Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking. Thread is a type of yarn intended for sewing by hand or machine. Embroidery threads are yarns specifically designed for needlework.

How do you classify yarn?

The three basic classifications of textile yarn include staple fiber yarn, which uses mostly short natural fibers to make yarn; ply yarns, which involve one or more strands of staple fiber yarn wound together; and filament yarn, which is wound from one or more long continuous filaments.

What are textile characteristics?

Textiles are specific types of materials characterised by a unique combination of properties including strength, flexibility, elasticity, softness, durability, heat insulation, low weight, water absorbency/repellence, dyeability and resistance to chemicals.

What is yarn classification?

How yarn quality is measured?

Fabric property is dependent on yarn quality and yarn quality depends upon its certain physical properties like yarn strength, unevenness, heaviness and geometrical parameters like diameter. There are two traditional methods used for yarn diameter measurement viz., rod method and traveling microscope method.

The Different Yarn Weights

  • Super Bulky or Super Chunky. Commonly used for heavy blankets and rugs, or chunky pullovers.
  • Aran or Afghan. Used for scarves, hats, garments such as jumpers and cardigans.
  • Worsted Weight or DK (double knitting yarn)
  • Sport.
  • Baby.
  • Fingering or Super Fine Weight.
  • Thread or Lace Weight Yarn.

1. Yarns made from short length fibers and the fabrics are like cotton and wool. 2. Short fibers twisted into continuous strand, has protruding ends 1. Dull, fuzzy look 2. Lint 3. Subject to pilling 4. Soil readily 5. Warm (not slippery) 6. Loft and bulk depend on size and twist 7. Do not snag readily 8. Stretch depends on amount of twist.

What is the quality of hosiery yarn?

The quality of hosiery yarn has to be considered with due weight-age to the fluidity of knitted structures and their influence on knit fabrics quality.

How much do yarn imperfection values vary between winding machines?

The yarn imperfection values produced from different winding machines have predominant effect. This variation in terms of CV\% is nearly 10 – 20\% between machines. It is found that the thick, thin and neps of yarn and its performance will be differing from machine to machine.

What is ‘textured’ yarn?

‘Textured’ is a general term for any continuous filament yarn whose smooth straight fibers have been displaced from their closely packed, parallel position by the introduction of some form of crimp, curl, loop or coil.
