Drawing Process In Yarn Spinning
Producing of yarn involve s various steps. Drawing is one of the most vital steps in yarn production and spinning and comes after blow room, carding, and combing. In drawing process, different types of fibres are blended, levelled and doubled. Drawing is a part of the yarn spinning process and is done to enlarge the silvers obtained from the carding process. Drawing is conducted in various yarn spinning mills and ensures that the silvers are consistent in size and have good strength. A draw frame is used in combining and drawing of fibre silvers which are obtained from textile fibres.
Drawing of the fibre makes the fabric strong and durable and therefore drawing is a crucial step of the spinning process. The drawing process is heavily reliant on the condition of the draw fame and therefore maintaining it at all times is important for the fabric spinners.
Why Is Fibre Drawing Done?
Drawing process is one of the most vital parts of textile manufacturing process and is crucial in spinning process. Drawing serves various functions and improves the quality of the end yarn. Following are a few vital functions of drawing process in yarn spinning:
1. Equalizing
Drawing process eliminates the unevenness, targeting short, medium and long fibre silvers. The silvers which are obtained from the combing process have unevenness in them and therefore cannot be smoothly processed for further yarn spinning. Drawing is therefore highly important as it eliminates the error caused by long silvers.
2. Parallelizing
It is highly important for the fibres to be arranges in a parallel manner while spinning them. Arranging the fibres parallel helps in achieving optimization in terms of the durability of the produced yarn, which is also highly important for the end textile product. Drawing achieves this parallel arrangement by drafting, as drafting a fibre helps in increasing its strength.
3. Blending
The spinners can adjust two parameters in the draw frame and get the ideal blend ratio. Blending gives the required variation to the yarn and also removes the unevenness from the fibres. Maintaining a blend proportion is highly crucial or the fore coming steps in the textile production which is done with the help of a raw frame blending.
4. Dust Removal
Presence of dust in the fibres can cause problems in the yarn spinning and can affect the overall quality of the end product. It therefore becomes important in the textile manufacturing process to remove as much dirt as possible within the textile manufacturing steps itself. Removing dust at the fibre stage of the textiles ensures maximum results. With the help of suction removal system, on can eliminate at least 80% of the total dust.
Maintenance Of Draw Frames
Draw frames are the most crucial part of the drawing process as it aims to enhance the internal structure of the fibre silvers, which results in uniform and consistent long segments. The quality of the draw frames is directly related to that of the end product. It is therefore important to upkeep these draw frames at all times, to avoid any potential defects and flaws in the production of the textiles. Checking humidity and temperature are two of the most common part so hr operational check up in draw frames. The pressure of the top rollers in draw frames is a crucial factor which needs tl be considered.
Drawing Process- Everything About Drawing Process In Fibre Spinning
Drawing process is a vital part of the spinning process. drawing process is the step which determines the overall quality of the textile and therefore needs to be done with care. Drawing process also facilitates blending of different types of fibres, therefore creating various types of blended fabrics. Drawing is the fourth step in yarn production and is done mainly to level and double the fibres. Drawing has various benefits to the yarn spinning processes. Drawing of fibres removes various types of impurities and dust from them. A suction removal system is a highly useful way to get rid of most of the dust from the yarn.
