On May 20, 1873, Jacob Davis and Levi Strauss received Patent No.139,121 from the U.S. Patent and Trademark Office. Thus began the production of the most popular clothing product in the world - the blue jeans.
In today's world, most jeans and denim garments are subjected to different degrees of 'distress washes' such as stone wash, pumice treatment, ice wash, etc. The types of wash are chosen to achieve a specific colour tone or to change the feel and structure of indigo denim fabric.
The selection of the sewing thread and zips is in part determined by the type and severity of the wash process. Other factors include the required colour fastness and the necessary durability of the seams. Read more advice and information on denim manufacturing in the articles below.
