Yesterday we talked about raw materials that determine the quality of fabrics. This is only one aspect, and the quality of the fabric is actually related to the spinning step. A clean cotton (to remove impurities): affect cleanliness and strength Open cleaning is the first process in the spinning process. The object of processing is cotton bales that are widely used in ginning. The raw cotton is opened, impurities are removed, different components are mixed, and rolled or sliced, and used for the next process. Impact: In addition to insufficient impurities and impaired fiber strength, the final yarn quality will be irreversibly reduced. The second comb (to be mixed into strips): affect cleanliness and uniformity Carding is the use of a flat or roller card, with the help of needle surface movement, the small cotton card is combed into a single fiber state, further remove impurities and non-spun short fibers, so that the fibers are parallel stretched, and finally made sliver Into the canister. Impact: The carding process best reflects the management level and equipment of a cotton spinning company. No matter how good the raw cotton is, if there is no good equipment and good people to operate, it will not be able to finally spin a good yarn. Triple Merging (Improvement of Structure): Impact on Uniformity and Weight After the fiber material is opened and combed from the front to the process, a continuous semi-finished product has been made. The quality and structural condition are far from the final yarn requirements, and the fiber's straightness and resolution are poor. Directly used in downstream processes will inevitably affect the quality of the yarns, so they must first be merged, drafted, and mixed into strips by the drawing process. Impact: The quality of the sliver will directly affect the quality of the final spun yarn and the quality deviation, and ultimately affect the quality of the fabric. Controlling the quality of the sliver is an important part of achieving high-quality fabrics. Four rovings (drawing twisting): effect strength and uniformity Roving is the process of processing the slivers produced in the previous process into rovings of different counts and different twists for subsequent spinning processes. Impact: The control of the roving process is not good, which will cause the end of the next process to be easily broken, uneven, and ultimately can not be used for fabric weaving with higher quality requirements. Five Yarns - Yarn Formation: Affects Yarn Accuracy, Strength The spinning process is the last process in spinning production. It is the spinning of rovings into spun yarns with a certain number of special qualities that meet the quality standards or customer requirements for twisting, weaving or knitting. Impact: Spinning is a very important process for spinning. The size of a cotton spinning mill is often expressed as the total number of spinning machines. Spinning production is the basis for determining the number of machines in each process of a spinning mill; production quality, raw materials, machine materials, and electricity The consumption, labor productivity, equipment availability, etc. reflect the production technology and management level of spinning mills. Six windings (reel removal): impact cleanliness and extensibility Winding (also known as winder) is the first process of preparation before weaving. Its task is to process the bobbin or hank from the spinning department into a bobbin that meets certain requirements on the winder. Impact: The winding quality is not good and will directly affect the quality of the downstream process. Seven Lines (increasing closeness): Impact strength and uniformity The purpose of the twisting of the strands is to increase their compactness. In addition to increasing the tightness, the purpose of twisting the strands can also be to change the package form and line density to meet post-processing and use requirements. Impact: Uneven twisting, insufficient tightness, or excessive density can directly lead to quality problems during the weaving process.
