Shankar-6 is a hybrid cotton variety grown mainly in Gujarat, and it is the most widely traded cotton in India. It is a medium-long staple cotton, usually around 28 to 30 mm, and spinners use it for everyday counts from 20s to 40s. For an overseas buyer its appeal is simple: it is available in large volumes, its properties are fairly consistent from bale to bale, and most Indian mills know exactly how to spin it.
The variety was developed for the Saurashtra and Kutch growing belt, where rain-fed and partly irrigated farms produce the bulk of Gujarat's crop. Ginning and pressing happen close to the farms, so bales move to Ahmedabad, Rajkot and the mills of south India without much handling. Export shipments usually leave from Mundra, Kandla (Deendayal) or Pipavav, all within a day's truck run of the main ginning towns.
Why spinners prefer it
- Consistent staple length, usually 28 to 30 mm, which suits the carded and combed yarns most garment fabrics use.
- Micronaire typically in the medium range, so the fibre is mature enough to take dye evenly without being coarse.
- Reasonable strength for its staple class, which keeps breakages down on ring frames running medium counts.
- Large crop volume, so a buyer can book a full season from one region without switching varieties part way through.
- Wide familiarity, meaning a spinner can quote and process it without trial runs.
What it is not suited for
Shankar-6 is not a fine or extra-long staple cotton. If your fabric calls for 60s or finer yarn, or for very high-strength sewing thread, you will usually need a longer staple such as a south Indian long staple variety or an imported cotton. Asking a mill to spin Shankar-6 to counts above its comfortable range tends to produce weaker yarn with more imperfections.
Quality also varies with the season. A wet picking period raises trash and lowers grade, and late-season bales can be more variable than the November to February arrivals. A buyer who specifies only "Shankar-6" without a grade, staple and micronaire range leaves room for the lowest acceptable bale to arrive.
How to specify it
Write the staple, micronaire range, strength and trash percentage into the contract rather than relying on the variety name alone. Ask for lot-wise test reports from an independent lab, and state which instrument standard the results should follow. Agree how disputes will be settled if a lot fails, and whether the price adjusts or the lot is rejected. If you are buying yarn rather than bales, ask the spinner to confirm the cotton used and to show the lot test reports, because the variety name on a yarn invoice is rarely checked.
What we do
We visit the ginners and spinners in Saurashtra and Kutch before you commit, and we draw sealed samples that go to an NABL-accredited lab in your name. We book the season with one approved supplier and one backup, supervise loading at the port and send you a short update each week. If you are planning a cotton programme, we offer a free 20-minute sourcing review to talk through the specification.
