This document discusses mixing and blending of fibers for fabrics. It begins with an introduction to how blended fabrics were created using natural and man-made fibers. It then defines blending as combining different fibers intimately to achieve desired properties. The rest of the document discusses reasons for blending fibers, methods for mixing and blending fibers, advantages such as improved properties and appearance, disadvantages such as difficulty achieving uniform blends, and examples of common fiber blends like cotton/polyester and their advantages.

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. 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. 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. 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. 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. 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. 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. 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. 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.  Spandex/Cotton:
o Stretchy
o Durable
o Absorbency
 Cotton/Polyester/Rayon:
o Strength
o Shine
o Softness
o Resilience
o Comfort

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.  Cotton/Wool:
o Comfort
o Absorbency
o Warmness
 Cotton/Rayon:
o Absorbency
o Durability
o Smoothness, shininess
o Comfort
o Cool effect

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
