Yarn engineering is the process of constructing yarns utilizing procedures designed to change the desired properties of the yarn itself. Conventionally, the textile industry has leaned towards a more experienced based and technological approach to making yarn; however, an engineering approach can provide an alternate viewpoint and wisdom that can possibly be overlooked by other methods. The specifics of this approach are geared toward optimization of cost and utility of the fabric being made.
Yarns are possibly the most versatile fibers used in fabric making. The ways in which they are put together as well as their individual properties determines the properties that they possess as a final product. The process of manufacturing yarn is a complex one and each step in this process can change the porosity, thinness, and flexibility of the final fabric. The steps are comprised of carding, combing, drawing out, twisting, and spinning.
Yarns are either synthetic of naturally made from fibers. There are differences between the two and one type may be chosen over another depending on the manufacturer and what they are looking for in their product. The two most common classifications in yarn making are staple spun and continuous filament yarn. Staple spun yarn consists of fibers that have restricted lengths and can be divided into the two subcategories of short and long staple. Any fiber with lengths of more than 2 inches crosses over into the long staple category. Continuous filament yarn is the second type of yarn and is make from long strands that do not break into smaller strands.
Synthetic fibers are much easier to handle and the process for making them requires much less energy and time. Most synthetic fibers are continuous filaments and made in chemical factories.
Natural fibers normally fall into the staple spun category and require much more experience and time to manufacture. Vast technological advancements have continued to make manufacturing natural fibers simpler and has contributed to them still being viable resources.
There are other fibers that can fall into the natural and synthetic categories. These are the most common fibers used today and are provided as exemplary fibers.
As stated above, each step in the process of making fiber into yarn is unique and can contribute different properties to the yarn. These steps are carding, combing, drawing out, twisting, and spinning.
Before the fibers can be carded they must be cleaned and separated. Natural fibers are normally the ones that need to be cleaned while synthetics only need to be separated. Each preparation process may be slightly different for individual fibers. Once this is finished the step by step process ensues.
Yarns come in many forms, shapes, and each have different qualities as well. Some factors during manufacturing can change the properties of the yarn itself as well. For instance twist. Twist in yarn redirects the effects of pressure and tension radially and allows the yarn to carry extra force without breaking. This can be useful if one wanted to make a durable yarn. other important qualities to consider include thinness, flexibility, and porosity to name a few. Porosity refers to the amount of wet the yarn will soak up, and is affected and can affect a number of other properties such as the feel of the yarn and how long it lasts.. Thinness and flexibility respectively refer to how fine the yarn may be and how much it stretches when axially loaded.
