Washing, pressing and quality control in knitwear
Finishing, dimensional change and handle in wool sweaters: wash and press trials, care labels and a pre-shipment inspection checklist.
Finishing changes appearance
Washing and finishing affect wool knitwear’s surface, handle and dimensions. The appearance that develops after knitting is particularly important with woollen-spun yarn. Processing conditions must be controlled to reproduce the result. This article does not provide a temperature, duration or chemical recipe suitable for every yarn.
Track dimensional change with records
Measure the same sample at defined points before and after treatment. Percentage dimensional change can be calculated as (final measurement − initial measurement) / initial measurement × 100. For example, a measurement changing from 50 cm to 48 cm has changed by −4%. Assess width and length separately; one percentage does not describe the behaviour of the entire garment.
Do not hide defects by pressing
A measurement temporarily brought to target by pressing is not proof of lasting conformity. Check again after relaxation and the intended care process. Inspect pressure marks, shine, neckline shape and pattern relief in the sample. Operating settings depend on the quality and equipment; general blog information does not replace machine instructions.
The pre-shipment acceptance file
At final inspection, review the measurement chart, colour and batch matching, surface defects, seams, accessories and labels together. A care label is not selected from the word ‘wool’ alone; it must be based on verified care conditions for the finished product.
