Fundamentally it is a mixing of the different colored fibers and yarns combined in one fabric. The methods may involve one of the following • Melange (yarn)—Fiber dyeing in different color and then mixing (in desired percentages) and
spinning. • Marl or Marled—Jaspe-Roving Grindle. • Cross dyeing—Using blended yarns and cross dyeing
Melange yarns The term "melange yarn" is derived from the
French word
mélange, meaning a mixture. Melange yarns are made with mixed fibers dyed before yarn
spinning. Melange yarns yield economical
blended textile materials.
Marl yarn Marl or Marled yarn is a
plied yarn. The doubling process produces the Marl yarn. Two yarns of different colors or may be of two different types are twisted together to make one. The texture of the resultant yarn is other than regular yarn. The process helps in producing fancy yarns. Jaspe is similar yarns produced by twisting different colored yarns or spinning yarn from two different colored
rovings.
Cross dyeing Heather yarn may be more expensive than regular yarns because of other processes involved during fiber dyeing or yarn dyeing in the case of heather effect. The cross dyeing of blends may also create the heather effect. Different fibers types respond differently to the
dyes. Cross dyeing is the way of dyeing constituting fibers in different colors. Selection of dyes and fiber composition plays a vital role in this case. It is important to note that depending on the percent of cotton, the fabric can still be legally labeled 100% cotton. == Importance and use ==
