Detailed description
The specification sheet for this item is short, which is exactly why it gets mis-bought. Two suppliers can both call a roll nylon hook and loop and still ship different yarn counts, different hook densities and a different put-up.
What the buyer is choosing
The mistake in comparing quotes is looking at the width and the colour and ignoring the yarn. A 25 mm roll at 380 g/m2 and a 25 mm roll at 300 g/m2 look identical in a photograph and behave completely differently after five hundred cycles.
The material question
The fibre is nylon (polyamide). It takes dye deeply, which is why the colour range is wide and why the colour holds through washing at 40 degrees. Its weakness is moisture regain: a nylon roll absorbs water in transit, measures wide on arrival and settles back over about a week, so allow for it in incoming inspection rather than rejecting the lot.
How it is quoted
Quotations are built from construction, width and colour, in that order. Change any one of the three and the price moves, which is why we ask for all three before quoting instead of sending a range and adjusting afterwards.
What ships with the goods
Each carton is marked with the lot number, width, colour and quantity, and the lot report references the same number. That is what makes a claim traceable six months later instead of a conversation about photographs.
Checking it on arrival
Weigh a metre of the roll. Weight per metre is the fastest proxy for yarn density, and it is the number that shifts quietly when a supplier tries to hold a price through a yarn increase.
Ask for a sample at your width; it ships in seven days and it settles the substrate, colour and hand questions faster than any specification sheet.
