Quality Fabric
Quality of fabric is key to the success of our business. This manual is to help
suppliers understand the criteria to determine a fabric to be correct for quality.
Suppliers must use the testing manual to select the required tests for product.
If you supply fabric which does not meet Standards you will be liable
for any returns & loss of profit to our business.
We reserve the right to request extra testing at any point in the sampling
& sealing process when deemed necessary.
WE want to make their customers happy by producing clothing to be as
easy as possible to care for. Therefore with this in mind, where possible we
expect all product to be machine washable at 40c & tumble dryable.
FABRIC APPROVAL PROCEDURES
TECHNICAL SUBMISSION
Technical Submission is the term used to describe a fabric at the development stage, a fabric
which is being proposed to Matalan but not actually bought yet.
A full physical test report must be submitted in line with the performance requirements. This can be in the form of a test report carried out for another retailer if available to save on testing costs or from an independent testing house.
The technical submission must be correct for handle, appearance and finish.
Technical Approval can only be given when the below is submitted to the Buying Team /
Technologist:
• Fabric Specification Sheet
• Technical Hanger
• Physical Test Report
Upon approval Technical Hangers must be distributed to Garment & Fabric Suppliers
BULK FABRIC SUBMISSION
Every fabric must be tested at 1st Bulk as per the required performance standard. Bulk
Approval can only be given when the below requirements are submitted to the Buying Team /
Technologist.
• Bulk Hanger
• 1st Bulk Test Report
• All Legal Testing ( fibre comp, flammability etc )
Bulk submission is required on the 1st Bulk of each design or colourway.
Some departments may require full/part garments to illustrate garment wash/placement etc.
Bulk Colour Continuity must be monitored ensuring that each batch is a close match to the
bulk hanger. If any batches are off-shade/borderline to the approved 1st Bulk Hanger, a A4
piece clearly labelled with the batch number must be submitted to the
Buyer/Technologist.
Bulk Shade Bands will need to be submitted on certain product areas. These occur with
certain was processes & dye routes e.g. pigment garment dye. 2 copies of each shade band
should be sent to the Buying Team for assessment. The bulk shade band should
consist of the lightest & darkest points that are deemed commercial against the bulk hanger.
