    Welcome to Salud Sytle core spun yarn spinning factory. Today I'm going to show you how the core spun yarn is made in our factory.

    In our core-spun yarn factory, the production of core-spun yarn is divided into the following processes: 

    opening and cleaning→ carding→ drawing→ roving→ spinning→ post processing.

    After this series of processes, the selected staple fiber will eventually become the finished core-spun yarn.

    Opening and cleaning process

    The first process is opening and cleaning, which can mix the different fibers and make them into a uniform fiber bundle, as well as remove the impurities. This process will last 3 times to ensure core spun yarn purity. We control the workshop moisture and temperature in all the processes to ensure the yarn strength and quality.

    In this process, the short fiber is made into a uniform fiber roll to create conditions for the carding process. This process can ensure the whole batch of short fiber will have the same strength and color when it's spun into thread.

    Carding process

    Next, the fiber bundles will go through the carding machine, to make themselves completely decompose into single fibers. The product after this process is card sliver.

    After opening and cleaning process, the fibers were loose and contained from 40% to 50% impurities. Carding process can mix the fibers evenly and be bundled with a single fiber that is parallel to normal, while also removing impurities with strong adhesion.

    Drawing process

    The quality of the card sliver is not good enough, and it needs to be processed into the drawn sliver. We will operate the drawing process for 2 times to ensure the yarn is of great evenness.

    In the drawing process, after the fiber strip is mechanically processed, the distance between the fiber and the fiber becomes closer, and the mixed composition and color of the fiber are more uniform. The treated fiber strips are wound into appropriate packages for use in subsequent processes.

    Roving process

    Next is the roving process, where the drawn sliver is processed into roving yarn, preparing for the spinning process.

    The main task of the roving process is to stretch and draw the fiber strips according to certain technical parameters, improve the parallel elongation of the fiber, and at the same time, the fiber gets the appropriate twist and is wound into shape, so as to facilitate the storage and use of the next process.

    Spinning process

    The spinning process is to spin the roving yarn into the spun yarn with certain specifications and quality standards. This process will determine the direction of the twist. We have 50 sets of spinning machines, and our daily capacity is about 20 tons.

    During the process, a proper twist is added to make the spinning yarn have a certain strength, elasticity, gloss, feel and other physical and mechanical properties. After this, the spun yarn would be ready for the subsequent process.

    Post processing

    The spun yarn is not big and convenient enough for textile manufacturing. Therefore, we will wind them into the bigger cone yarn. If the yarn is used for the industries like fabric manufacturing, then the cone yarn is the final product after this process.

    Although the spinning of the spinning machine has basically completed the spinning task, it does not mean the completion of the whole spinning project. The post-processing process mainly has the following four purposes:

    (1) Improve the internal performance of products

    (2) Improve the appearance quality of products

    (3) Stabilize the structural state of the product

    (4) Make the appropriate roll form

    Winding Process

    Plying Process

    If the yarn is used for the industries like sweater manufacturing, then the plying process is necessary. This process will make 2 of the single yarn into 1 double plied yarn, and make sure all of them are at the same weight.

    Twisting Process

    Next is the twisting process, which is to make the yarn have higher strength and elasticity. It can also make the fabric and sweaters achieve the anti-pilling effect.

    Packaging

    Finally, the high-quality core spun yarn will be automatically packaged up by the machine. That's all about core yarn spinning. Welcome to visit our factory. If you have any questions, please do not hesitate to contact us.
