There are many types of yarns
with different properties. It can be pure spun yarn made of natural fibers or various chemical short fibers, blended yarn made of several kinds of fibers, or filament yarn made by direct spinning of chemical fibers. Generally speaking, yarn can be classified according to raw material, yarn thickness, spinning method, spinning system, yarn structure and yarn use.
According to the yarn material:
1. Pure spinning yarn is a kind of yarn spun from fiber materials, such as cotton yarn, wool yarn, hemp yarn and silk thread. This yarn is suitable for making pure textiles.
2. Blended yarn is a yarn made of two or more fibers, such as polyester-cotton blended yarn, wool viscose blended yarn, etc. This yarn is used in fabrics that highlight the advantages of the two fibers.
divided by yarn thickness:
1. Coarse special yarn: Coarse special yarn refers to yarn of 32 tex and above (18 yarns and below in British system). This yarn is suitable for thick fabrics such as tweed and plain weave.
2. Mid-special yarn: Mid-special yarn refers to 21~32 special yarns (19-28 counts in British system). This kind of yarn is suitable for medium and thick fabrics, such as medium plain cloth, gabardine, khaki, etc.
3. Fine special yarn: Fine special yarn refers to the yarn of 11-20 special (English count 29-54). This yarn is suitable for thin fabrics such as muslin and poplin.
4. Superfine special yarn: Superfine special yarn refers to the yarn of 10 tex and below (58 counts and above in British system). This yarn is suitable for high-end fine fabrics, such as high-count shirts and worsted sweaters.
According to the spinning system:
1. Worsted yarn, also known as combed yarn, refers to yarn spun through a combing process, including combed cotton yarn and combed wool yarn. The parallel and straightness of the fibers in the yarn is high, the evenness is smooth, but the cost is high, and the yarn count is high. Combed yarns are mainly used as raw materials for high-end fabrics and knitwear, such as worsted spinning, gabardine, tweed, sweaters, etc.
2. Core-spun yarn, also called carded wool yarn or carded cotton yarn, refers to the yarn that is combed according to the general spinning system without going through the combing process. There are many short woolen fibers, poor parallel straightness, loose structure, more hairiness, low yarn count and poor quality. This kind of yarn is mainly used as a raw material for general fabrics and knitwear, such as wool fabrics, medium and high-grade cotton fabrics, etc.
3. Waste spinning refers to yarn spun from textile waste (waste cotton) or mixed with low-grade raw materials. The yarn is of poor quality, softness, unevenness, a lot of impurities, and poor color. Generally, it is only used for weaving low-grade fabrics such as coarse cotton blankets, thick flannels, and packaging cloths.
