Single jersey knit supplier in Bangladesh

Buying single jersey knit in Bangladesh

Single jersey is the plain weft knit, made on one set of needles of a circular machine, with V-shaped loops on the face and rounded loops on the back. It stretches both ways, curls at cut edges, and can shrink and grow. It is the usual cloth for T-shirts and casual tops.

Two jerseys at one GSM can feel and shrink differently, because weight follows yarn count and loop length together. A single jersey knit supplier in Bangladesh should work to all three. Roptan sources from verified mills, writes them into the order and checks the first rolls.

Kinds of single jersey knit

How to brief a single jersey knit supplier in Bangladesh

Count and stitch length

State the count in Ne, combed or carded, and the stitch length beside the GSM. Mills usually set weight through count, stitch cam setting and yarn tension.

Finished GSM and width

Quote finished figures, not grey. Compacting usually raises GSM and shortens length, and heavier jersey is run with more overfeed at a narrower width. Width is usually traded in inches.

Open-width or tubular

Tubular jersey stays a tube; open-width jersey is slit and finished flat. Each usually runs on its own compacting route, so finished width and shrinkage control differ.

Shrinkage both ways

Compacting cuts lengthwise shrinkage but usually does little across the width. Ask for both results after a named wash, and say whether the roll must be compacted.

Tolerances in writing

ASTM D3887, the old tolerance specification for knitted fabric, is withdrawn, so agree GSM, width, shrinkage and spirality limits in the order.

Tests and certificates for single jersey

ASTM D3776/D3776M

Mass per unit area, active and applicable to most fabrics, with an option for a small swatch sent to a lab. ISO 3801 is for woven fabric only.

ISO 16322-2 and EN ISO 5077

Spirality and dimensional change, both measured after an EN ISO 6330 wash programme you name. Use the same programme for sample and bulk.

EN ISO 3071, 14184-1 and 14362-1

pH of the water extract, formaldehyde and certain azo colourants: chemical tests for jersey worn next to skin. Ask for a report per colour, with lab name and date.

OEKO-TEX Standard 100

Choose the class by skin contact: class 1 for babies up to 3 years, class 2 for direct skin contact. Check the certificate number in the issuer's Label Check.

What moves the price of single jersey

• Yarn: count, combed or carded spinning and the blend set the kilogram price before knitting starts.
• Weight: with the same yarn and process the kilogram price usually holds across GSMs, so heavier jersey costs more per metre.
• Cotton: Bangladesh grows under 2% of the cotton its mills use, so world prices and the exchange rate pass into yarn.
• Energy: gas shortages have forced many spinning and dyeing units to run far below capacity.

Lead times and delivery

Dates depend on the mill's yarn and dyeing schedule, so Roptan quotes them per order. Yarn in stock and a running shade shorten the time; a new yarn booking, a difficult shade, certified fibre and extra lab dips lengthen it. Ask whether the minimum is per colour or per dye lot. Roptan confirms dates and the minimum in the quote.

We deliver jersey rolls to cutting rooms anywhere in Bangladesh. Mould can grow on clothing at about 62 to 93% relative humidity and 25 to 31 °C, common monsoon conditions, so ask for poly-wrapped rolls. Exporters usually receive the fabric against a back-to-back letter of credit; local buyers get a VAT invoice (Mushak 6.3).

Buying single jersey knit for export

For buyers abroad, Roptan quotes FOB Chattogram (Chittagong), rolls packed by shade band. Dyed cotton jersey usually enters under heading 6006, stretch jersey with 5% or more elastane under 6004; your broker confirms the line. For GOTS jersey, every company that handles the fabric must be certified, the dyer included.

• Finished GSM and widthWe check finished GSM and width on rolls from each lot against the tolerance in your order.
• Washed pieceWe have a piece washed to your named programme and measured for shrinkage both ways and spirality.
• Shade band on every rollLarge orders are dyed in several lots that can differ, so we check every roll carries its shade band number.
