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.
o Blended fabrics are created when two or more different kinds of fibers
are mixed together to create a new fabric with unique properties
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.
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.
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.
METHODS FOR MIXING & BLENDING
o The fibre are spread one on top of the other and fed into the
o The blending can also be done in the CARDING STAGE.
o A blended filament yarns of different deniers.
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
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.
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.
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
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:
o Crease Resistance
o Less ironing
o Crease Resistance
o Drape better
o Vivacious colouring impact
o Skin friendliness
o Smoothness, shininess
o Cool effect
o Crease resistance
o Wrinkle resistance
