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
Two things decide whether a roll suits an automated line: the width tolerance at the core and the outside of the roll, and whether the put-up is splice-free. Ask for both in writing. A supplier who quotes a tolerance only for the finished carton is quoting the wrong measurement.
The material question
The construction is a woven hook and loop face in the standard grade: enough hook density for a normal closure, priced for volume rather than for a five-year service life. If the application cycles more than a few thousand times, ask for the higher-density weave instead of paying twice for the same part.
How it is quoted
Minimum order is 500 m in a stock colour and 3,000 m for a custom dye run. The dye minimum is a machine load, not a policy: below it the lot cannot be dyed evenly, and a split lot reads as two colours under D65.
What ships with the goods
Certificates are issued per lot rather than per year, and REACH and RoHS declarations travel with the shipping documents. OEKO-TEX documentation is available on request for skin-contact applications.
Checking it on arrival
Do the peel test on the material you will actually bond to, not on a steel plate. The number in the specification is a reference value measured on steel; on powder coat or on a textile it will read differently, and that difference is the one your customer will notice.
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.
