The term 'Causes of Puckering' can be summarized by the crossword solution 'TANGS'. TANGS stands for Textile Abrasion and Napping, which are two of the most common causes of puckering in fabrics. Textile abrasion is caused by friction between the fabric and other surfaces, while napping is caused by the fabric's fibers becoming tangled or matted. Both of these causes can lead to puckering in fabrics, which can be unsightly and reduce the fabric's lifespan.
