Starch Can Reduce the Wear Life of Your Shirt
Which is more important: a very smooth, bright skirt which resists stains and has great flat abrasion resistance, or a shirt with reduced strength and flex abrasion resistance? That is the trade-off made by consumers who starch their 100% cotton shirts. The starched shirts unquestionably looked better in a study conducted by the International Fabricare Institute, but heavily starched shirts are more rigid, and snap rather then stretch when flexed. This decreases tensile strength, and might allow for quicker popping of elbows through sleeves over the life of the shirt if it is always worn starched. However, testing a shirt which has been heavily starched after removal of the starch indicates that the tensile strength reduction is directly related to the presence of the starch and is not a permanent change in the cotton, so you can get longer wear out of the shirt by sacrificing appearance and abandoning starch.
