Dr. B.M.N._Blending and mixing

  1. 1. Mixing and blending of fibres & Fabric Geometry Department of Textile Science and apparel design Dr. B.M.N. College of Home science 2016-2017 PRESENTED BY S.Y.T.S.A.D (GROUP 3)
  2. 2. Mixing and blending of fibres
  4. 4. INTRODUCTION o Until the end of last Century, only the natural fibers were available. o Then the blended fabrics were created. o In the type of combination fabrics, one yarn of one fiber type and another yarn of another fiber type were woven together. o As there was a rapid growth in the manufacturing of man-made fibers, a trend to combine two or more fibers was introduced. o These blends and mixtures were then successfully used in all types of apparels, upholstery and furnishings.
  5. 5. MEANING o Blended fabrics are created when two or more different kinds of fibers are mixed together to create a new fabric with unique properties Or o A yarn or fabric made from two or more different fibers. These blended fibers are found in each of the yarn in the fabric.
  6. 6. DEFINITION o Blend: Blend is the combining of different fibers together intimately to achieve a desired product characteristic. Blend can influence coloring, strength, softness, absorbency, easy care, resistance to wrinkling, ease of spinning, cost, etc. o Mixture: A mixture is a fabric which has one type of fiber in one direction and another type in the other direction.
  7. 7. REASONS FOR MIXING & BLENDING o To improve the wear performance of the fabric. o To achieve aesthetic qualities i.e. appearance, texture and drape. o To obtain cross-dyed effect. o To improve spinning, weaving, dyeing and finishing efficiency. o To achieve on economic savings. o For producing permanent pleated fabrics. o To get resistance to moth and mildew. o For comfort and ease in washing, easy care. o Resistance to chemicals. o Improving absorbency.
  8. 8. METHODS FOR MIXING & BLENDING o The fibre are spread one on top of the other and fed into the blending feeder. o The blending can also be done in the CARDING STAGE. o A blended filament yarns of different deniers.
  9. 9. ADVANTAGES OF BLENDED FABRIC o Fibres are blended to get the properties of these two fibre. E.g. Cotton/polyester. Cotton provides the absorbency and polyester provides strength. o Blending is done to produce a fabric which is very costly. E.g. Silk can ne blended with cotton or polyester. o Blended also helps to provide the fabric light weight with all desirable characteristics. E.g. Improving spinning weaving, and finishing efficiency and the uniformity of product.
  10. 10. o To improve appearance of the fabric. o To improving properties. o Improve handle of fabric. o Improve profitability of a fabric making in cheaper to produce.
  11. 11. DISADVANTAGES /PROBLEMS OF MIXING & BLENDING o Sometimes some fibres may be hard and may cut the other softer fibre which may effect durability. o The manufacture may face some problem with, which fibres to blend and in what proportion to blend. o For blend there can’t be a general procedure for care, it will depend upon the particular fibre and finish applied to it. E.g. Cotton/wool can’t be washed with alkaline soap. o It may be difficult to get a uniform blend of the fibre in yarn because of different in specific gravity, length, diameter, surface, shape, lustre of the fibre.
  12. 12. TYPES OF BLENDS Blending fibres in a fabric can help to prevent wrinkling or lower the cost of a garment. Types of blends and their advantages are as follows:  Polyester/Cotton: o Crease Resistance o Comfort o Less ironing  Linen/silk: o Crease Resistance o Lustre o Durable o Drape better
  13. 13.  Spandex/Cotton: o Stretchy o Durable o Absorbency  Cotton/Polyester/Rayon: o Strength o Shine o Softness o Resilience o Comfort
  14. 14.  Cotton/Silk: o Upholstery o Smoothness o Vivacious colouring impact o Skin friendliness  Wool/Polyester: o Warmness o Breathable o Strength o Drapability
  15. 15.  Cotton/Wool: o Comfort o Absorbency o Warmness  Cotton/Rayon: o Absorbency o Durability o Smoothness, shininess o Comfort o Cool effect
  16. 16.  Rayon/Polyester: o Strength o Crease resistance o Comfort o Durability o Absorbency o Uniformity  Linen/Cotton: o Strength o Lustre o Wrinkle resistance o Comfort o Durable
