Hi,
To understand Top Dyed yarns, its necessary to know about Melange yarns first.
A melage yarn is the yarn which is produced with various combinations of Raw White & Dyed Cottons or dyed fibres.
For example, if we produce a yarn with 100% Cotton, then it will call as normal "Raw White" yarn, or Grey yarn or Natural colored yarn or acru yarn.
Now if we mix 99% Raw White Cotton & 1% dyed Cotton (of any color), then it will called "Melange" yarn.
Similarly, we can generate hundreds & hundreds of shades by mixing various % of Cottons with various ratios.
All the formed yarns in same method will called "Cotton Melange Yarns".
Now lets consider the following combinations
99% Raw White Cotton + 1% Black Polyester
98% Raw White Cotton + 2% Black Polyester
95% Raw White Cotton + 5% Black Polyester
.
.
.
can generate many many shades with different ratios of dyed polyester & in different colors.
AND THE YARNS PRODUCED THROUGH THIS TECHNICES ARE CALLED AS "POLYESTER MELANGE YARNS", OR "HEATHER GREY YARNS" OR ALSO "TOP DYED" YARNS.
Therefore, generally the melange yarns of dyed Polyester combinations are to be referred as "Top Dyed" yarns.
But we cannot fix this definition specifically for "Top Dyed" also because there are many customers in Far-East countries, who has fixed the term "Top Dyed" for all kinds of Melange yarns. They never mention that whether these are Cotton Melanges or Polyester Melanges !!!
Just for additional informations, Melange yarns can also be produced with other fibres too like Viscose, Rayon, Bamboo, Modal, Coolmax, Tancel, Soyabean, Cashmere, etc. Hope it will help. In addition to above answer, please also note that fabrics produced with Melange yarns (either from Cotton melange, heather grey, or else) are not dyed further usually to make garments and fabric is used as it is.
the fabric weave by dyed yarn called yarn dyed fabric
yes
Jacquard is a type of weave usually with a pattern on it. Each yarn is a different color and are woven together creating a pattern. Yarn dyed sheets were dyed in the yarn stage not dyed as a whole sheet like cheaper sheets would be.
According to color, pure cotton can be divided into plain cotton, white sheeting, yarn-dyed fabric and print fabric. Plain cotton is dyed by one single color, and there is no pattern. White sheeting is the fabric which treated with bleaching. Print fabric is the fabric which treated with printing process. The pattern is clear and color is bright in front while fuzzy and dark on the other side. Yarn-dyed fabric is called yarn dye in Japan. Most fabric is dyed after piece goods, while yarn-dyed fabric dyes the cotton yarn first and then spinning. We often see some fabric such as plaid fabric and chambray are all belonged to yarn-dyed fabric. Actually, jean also belongs to yarn-dyed fabric, and it is usually dyed from indigo warp yarn and natural color weft yarn.
coefficient of variation in yarn
Basically neps is a problem of yarn but it may be a ornamented yarn if it can be arranged in a organized way. As for example: (95%Cotton+5%Polyester) Neppy Yarn Base yarn is cotton & if some dyed polyester of different color can be sprayed throught its length & base yarn is dyed then one kind of neppy effect will be visible throughout the length of the yarn. This yarn is called Neppy Yarn.
D.M.M = Dyed Metric Measurement. Means yarn count being measured after dying yarn. Cheers - Trevin Alles
