Though monofilament is strong, uniform and inexpensive to make, it lacks flexibility and is stiff and scratchy in feel. Monofilament Thread is made from a single continuous fibre with a specified thickness. Three types of filament threads are commonly used: Corespun thread is generally used for the high-speed sewing of many garment types, especially those requiring high seam strength.įilament threads are stronger than spun threads of the same fibre and size. This thread structure influences the strength of filament polyester and the sewability of cotton or polyester fibre wrap. The most commonly used corespun thread has multiple-ply construction, with each ply consisting of a polyester filament core with cotton or polyester fibres wrapped around the core. It is stronger than cotton threads of a comparable size, and is available in a wide variety of sizes and colours.Ĭorespun Thread is a combination of staple fibres and filaments. Spun polyester is one of the most widely used threads. Spun Thread is made using natural or synthetic fibres. Classification based on construction thread structure They are also not significantly affected by moisture, rot, mildew, insects or bacteria. Syntheticĭue to the limitations of natural fibres, thread users have turned to threads made from synthetic fibres as they have desirable properties of exceptionally high tenacity, high resistance to abrasion and good resistance to chemicals. However, the most commonly used natural thread is cotton thread. The usage of thread made from natural substrates is now minimal in industry applications. Classification based on substrate Natural Some common classifications are those based on:ġ. Thread can be classified in different ways.
Sufficient surface smoothness, to pass easily through the machine guides. Evenness, to prevent changes in tension during sewing. The parameters that define the superior sewability of thread are: It also minimises thread breakages and the associated costs incurred from rethreading machines, repairing stitches and producing inferior quality products. Longitudinal uniformity of thread contributes to uniform strength and reduced friction, as it passes through the stitch forming mechanisms. A thread with good sewability is uniform in diameter with a good surface finish. 'Sewability' of thread is a term used to describe a sewing thread’s performance. Thread performance in garments can be evaluated from its: Thread used in garments must be durable enough to withstand the abrasion and needle heat that occur while sewing, garment finishing, stretching and recovery during wear. What are the factors that affect functions of a sewing thread? Factors affecting aestheticsĬolour, lustre and fineness / thickness should be considered while selecting a thread for decorative purposes such as top stitching or embroidery. The basic function of a thread is to deliver aesthetics and performance in stitches and seams. They form efficient stitches without breaking or becoming distorted during the useful life of the product. Sewing threads are special kinds of yarns that are engineered and designed to pass through a sewing machine rapidly. This Bulletin Post serves an introduction to the types of threads, the properties, thread construction, and factors affecting thread performance. Enhancing thread knowledge, analysing thread parameters, the right selection procedure and use of thread plays a major role in achieving good sewing performance and the desired seam quality. Hence, it is important to know your thread thoroughly. The smallest failure in thread performance results in losses on investments in material, equipment, garment engineering, and labour.
