Selecting the Correct Sewing Thread By Kim Anderson, [TC]² Though it is often invisible and comprises a very small portion of the retail selling price of a product, sewing thread is an integral component of the garment. Typically, the cost of thread is less than 5% of the retail selling price. Since the vast majority of seams in a garment are held together by sewing thread, it is important to recognize that 50% of the responsibility of the garment’s performance is dependent on sewing thread. Some sewing problems that result from improper thread selection include breakage, skipped or irregular stitches and seam pucker. The properties of the sewing thread determine how compatible it will be with the fabric. The various properties of thread which are discussed below are interrelated. Changing one property such as the fiber type can affect one or more of the other properties—adversely affecting garment quality, performance and/or manufacturability. Sewing Thread Properties The most important properties of sewing thread that impact quality, performance and manufacturability are: thread color, strength, uniformity, fiber type, finish, size, twist, shrinkage, elasticity, elongation and structure. The importance and impact each property has on quality and manufacturability are reviewed in the following text. The importance of thread inventory will also be discussed. Thread Color Thread color impacts quality. The hue, shade and luster should all be considered. The highest quality garments utilize a thread color that matches the dominant color in the fabric. For the best match, usually a slightly darker thread color from the dominant fabric color is selected. To save on cost basic colors such as black and white can be used in areas that are not visible.
