Shaoxing Mujia Textile Co., Ltd. publishes the yarn construction behind its 280 GSM cotton canvas: 10S/3 three-ply, not a bulked single.

Zhuji, China – November 12, 2026 – Shaoxing Mujia Textile has published the yarn construction behind its 280 GSM (grams per square metre) cotton canvas, on the argument that the weight figure alone cannot distinguish a three-ply canvas from a bulked single that weighs and measures the same.

The distinction sits in the specification code. 10S/3 does not mean size 10. It means three plies of a 10-count single yarn twisted together into one strand. A buyer reading only the GSM is reading the half of the specification that both a three-ply cloth and a bulked single can satisfy.

The construction is what the cloth is for. A single 10S yarn at 280 GSM would need an unusually dense sett, the number of yarn ends per inch, and the resulting cloth would be stiff in one direction and slack in the other. Three plies twisted together produce a round, balanced strand that resists abrasion from every angle, which is what a bag, an apron or a work jacket asks of it. 10S/3 in the warp and 10S/3 in the weft, the lengthwise and crosswise yarns, is a balanced construction: same yarn both ways, so the cloth behaves the same along and across, takes a fold without cracking and a seam without puckering.

Below 240 GSM the same construction reads as a light twill, fine for shirting and too floppy for a tote. Above 320 GSM the plies start to show at a fold and the cloth becomes a tarpaulin rather than a canvas. 280 GSM sits where the cloth holds a shape when cut but still folds at a seam allowance. That is the working definition of canvas, and it is why the number repeats across the industry even though the constructions behind it differ.

Three checks separate the two, and none needs a lab.

Fray one edge of a 10 cm square with a thumbnail and count the strands. A 10S/3 shows three distinct plies twisted together. A bulked single shows one strand with a soft, hairy surface and no visible twist structure.

Rub the frayed edge between finger and thumb twenty times. The three-ply holds together. The single pills and sheds.

Fold the square sharply, press the crease with a thumbnail and open it. A balanced 10S/3 fold shows a clean line. A single-ply fold shows a white break along the crease where the fibres have separated.

“Most buyers check the weight and stop,” says Emily Zhou, founder and director of Shaoxing Mujia Textile Co., Ltd. “The weight is the easy number to state. The ply count is the one that decides how the bag holds its corners over a season.”

The canvas runs 280 GSM, 8.3 oz, 150 cm wide, 100% cotton, in 55 solid colours. Width matters more on a bag than on a garment, because a bag panel is cut as one piece and a 2 cm shortfall means a narrower bag rather than a smaller seam allowance. The finished width is what counts, not the nominal width in an email.

End uses are workwear, bags, aprons, home textiles, caps and sneaker uppers, where the balanced construction matters because the cloth is cut on the bias and stretched over a last. The mill does not run a coated version. Water repellency is a finish applied at a partner mill and it changes the hand of the cloth.

The mill weaves in Fengqiao, Zhuji, on 30 Lenado air-jet looms in a 5,000 square metre shed, about five million metres a year, and has done since 2012. It weaves and does not dye. Dyeing runs at partner mills and the mill holds the shade approval and the AQL 2.5 inspection, the acceptable quality limit sampling level, with a four-point check on every roll.

Running lead time is about 15 days after colour confirmation, with 300 m per colour as the standard minimum.
