Introduction to the Basic Principles of Poy Spinning

Textile machines twist many animal and plant fibers together to produce yarn, which can be used to weave fabric. The earliest poy spinning machines were very simple in structure and were first used in the 14th century. After the 18th century, better yarn spinning machines were invented, which made the textile industry the largest industry. All poy spinning machines only do two things: first, they aggregate a large amount of short fibers into loose cotton thread, and then they slowly pull out the cotton thread and twist it into fine, dense cotton thread, which lengthens the cotton thread through twisting.

What is poy spinning?

Poy spinning itself belongs to a very ancient activity, which dates back to prehistoric times, where humans learned to spin shorter fibers into longer threads and then weave them into fabric. The so-called poy spinning is a behavior of taking animal or plant fibers and using twisting to make them adhere into a continuous, indefinitely extensible yarn, which can be used for weaving. The twist of the yarn itself will naturally and tightly hold the fibers together, making it very favorable for weaving or knitting. The twist of the yarn is related to the diameter of the yarn and is measured by the number of turns per inch, and is expressed as low, medium or high. Usually, the higher the twist, the more turns the yarn has, indicating that the strength of the yarn is better. Low twist yarn is commonly used to make smooth, lustrous, or soft matte fabric, while high twist yarn is needed to create textured or rough-surfaced fabrics.

The basic principle of poy spinning

Next, jwell machinery will share you the basic principle of poy spinning. Textile spinning is the science of processing short textile fibers into yarn, which is usually made by twisting many fibers of varying lengths together or combining very long continuous filaments. 

Removing impurities from the raw materials is the first step in the poy spinning process, also known as preparing the spinning material. Different types of raw materials, different types and properties of impurities, and different methods and techniques of processing are used. The main methods for primary processing of raw materials include physical methods (such as cotton rolling), chemical methods (such as degumming of flax and refinement of silk), and physical and chemical methods combined (such as washing and carbonizing wool).

To transform the disordered, transversely compacted fibers into smooth yarns with specific requirements, it is necessary to transform the block-like fibers into single-fiber states, remove the transverse connections between fiber materials and establish a firm longitudinal connection from beginning to end. The former is called fiber loosening and the latter is called fiber assembly.
