Seersucker Shirt Fabric
Seersucker is a fabric synonymous with summer and warmer weather.
Seersucker is a thin, puckered fabric used to make clothing for spring and summer wear. Seersucker is woven in such a way that some threads bunch together giving the fabric a unique texture.
Most fabric lies flat on your skin, and this even texture on your skin is not conducive to air flow. The puckered (or uneven) texture of seersucker, naturally creates an air flow and facilitates heat dissipation.
Seersucker became popular in the British Colonial Period, in warm weather colonies, like India. When seersucker was introduced in the United States, the South naturally gravitated towards the fabric and soon used seersucker in many types of clothing.
Seersucker is made by slack-tension weave. The threads are wound onto the two warp beams in groups of 10 to 16 for a narrow stripe. The stripes are always in the warp direction and on grain. Today, seersucker is produced by a limited number of manufacturers. It is a low-profit, high-cost item because of its slow weaving speed (source: https://en.wikipedia.org/wiki/Seersucker).
