What is yarn spinning

Yarn spinning is the technique of making yarn from fibers. The fibers can be wool, cotton or other natural materials or synthetic. Spinning produces yarn that can then be used to make cloth.

Types of Yarn Spinning

Spinning can take many forms, but they all have the same goal: converting fibers into yarn. Some types of spinning are more popular than others, but each has its own benefits.

Wool and cotton are the two most common forms of spinning. The process of turning raw wool into yarn is called spinning. The yarn is generally thick and heavy as it is spun on a spinning wheel. Cotton spinning is the transformation of raw cotton into yarn. The yarn is generallymean thin and light and is spun on a spinning wheel or spinning machine.

There are altherefore other types of spinning that are less laborious have their own advantages. The process of transforming raw silk is called silk spinning. Yarn is generally very thin and delicate as that is where it is spun. The process of spinning raw hemp into yarn is called hemp spinning. The yarn is generally extremely fine and strong as it is spun on a spinning wheel. There are also chemical fiber spinning such as wet spinning and melt spinning to be introduced in the future.

Cotton SpinningCotton Fiber

The production of cotton fiber is the largest among natural fibers. And they are very versatile. We can use them to sew clothes, sheets, bedding and other life items. They can also be used as canvas and conveyor belt materials. Or we can flake it forwhich process heat preservation and filling materials.

Cotton fibers are divided into fine cotton and long-staple cotton. Compared to fine wool cotton, long wool cotton is whiter, finer, longer and shinier. It is the best grade of cotton and is generally used for high quality fabrics.

Cotton Spinning System

Raw materials used in cotton spinning production include cotton fibers and cotton-like chemical fibers, and their products include pure cotton yarns, purified fiber yarns, and various blended yarns. In the cotton spinning system, it is divided into a carding system, a combination system and a waste spinning system according to the raw material quality and yarn quality requirements.

Auto Ding system

Typically used for spinning coarse and medium specialty yarns and weaving ordinary textiles.

Combing System

The combing technique is used to produce high-quality cotton yarns, unique yarns, etc. Cotton and chemical fiber blended yarn.

Waste spinning system

Waste spinning systems are becoming Production of inexpensive coarse cotton yarns used.

Cotton and chemical fiber blending system

Due to the different properties and impurity levels of polyester and cotton fibers, they cannot be combined when blended and processed in the cleaning and carding process. To ensure proper blending, use three puffs when blending above.

The cotton spinning process begins with harvesting the cotton plants. The cotton is then washed and sorted by size. Then the cotton in thespinning machine given. Spinning machines twist cotton fibers into cotton yarn.

Wool SpinningWool Fibres

Wool is a traditional natural fiber with unique properties that cannot be replaced by synthetic fibers and has many ideal uses. The properties of wool fibers show that wool is a versatile fiber that can be fiberized into different colors and fineness qualities, such as paint rollers, mattress pads, blankets, outerwear, finishing fabrics, haute couture, carpets, curtains, screens, ski wear and tennis covers, etc .

Advantages

1. Wool fibers have an inherent ability to insulate against heat and cold, as well as the ability to absorb water and vapor. Wool goods have a natural insulating effect due to the air between the crimped strands of wool. They can absorb 30% of their own weight, grow until they are wet to the touch, and after the auWhen absorbing moisture, the fiber generates heat. Therefore, when wool fibers are worn on the human body, they tend to feel warm and dry rather than cool and sticky.

2. When wool absorbs moisture from the air, it tends to block liquids from entering. The liquid on the surface of the wool fibers rolls off the fabric, helping to resist dust. This may also make the fabric look younger over a longer period of time. When the woolen garment is finished, it returns to its original shape.

3. Wool is quite a large industrial raw material used in the fashion industry. It is anti-static, easy to sew, has excellent draping resistance to dust, easy to dye, easy to iron, and has a beautiful shape. And it can keep people cool in hot weather and warm in cold weather.

Cons

1. The wool fabric feels thick and sparkly on the Haut on. The weight of wool textiles is determined by the yarn. However, since wool yarns are typically used to enable smooth finishing, it is difficult to produce lighter fabrics, which is why wool fibers cannot be used in various industries.

2 Hairiness is a significant problem in wool yarns, affecting the wool textile business. The hairiness of wool yarn was discovered as a characteristic feature of wool yarn as early as 1950. Yarn hairiness is detected by counting the number of hairs within a certain distance on the yarn body. The hairiness of yarn is untidy and disordered on the package, and there are also protrusions, fiber tails or head ends, fiber loops, etc. In ring spinning, most of the hairiness protrudes from the end of the package.

Wool spinning system

The wool spinning system uses Wool fibers and wool types Chemical fibers as raw materiale and the entire production process of spinning wool yarn, mixed yarns from wool and man-made fibers and spinning pure man-made fibers on wool spinning devices.

(1) carded wool spinning system

(2) worsted spinning system

The worsted spinning system has many procedures and a long process that can be divided into two parts: sliver making and spinning.

The production of combed wool is also called rug making. A separate factory can be set up and the product (combed wool blanket) can be sold as a commodity.

Some worsted mills do not have a worsted wool manufacturing process and use combed wool fibers as raw material. The production process includes roving and post-spinning; the combing process is similar to that of the sliver manufacturing process. In addition, there is also a semi-worsted spinning process system between combed and carded.
