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
Colour is a specification, not a preference. Dyed lots are matched to a retained standard under D65 light, and a black that matches in an office can read green in daylight. If the colour is customer-facing, approve a physical swatch and keep it, because a photograph is not a standard.
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
Widths are slit from the master roll in one millimetre steps between 10 mm and 150 mm, held to plus or minus 0.5 mm. A width that is not on the list is a slitting instruction, not a new tool, so it does not add lead time once the master exists.
What ships with the goods
Colour is checked against the retained standard under D65 on every lot, and weft skew, oil marks and hook damage are inspected across the full roll rather than on a cut sample.
Checking it on arrival
On arrival, measure the width at the core and at the outside of the roll before you cut anything. A roll that measures wide at one end and nominal at the other was slit under uneven tension, and the whole lot will behave the same way on your line.
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.
