The textile fiber material in S4 is natural fiber.
In summary, in the manufacturing process of the anti-static covered yarn, the defects are firstly cleaned in the spinning process, that is, the raw material is subjected to primary processing, which is also called as the preparation of the spinning raw material. The types of raw materials are different, the types and properties of impurities are different, and the processing methods and processes are also different. The primary processing method of the raw materials mainly comprises a physical method (such as cotton ginning), a chemical method (such as degumming of hemp and refining of spun silk) and a physical and chemical combined method (such as washing, grass removal and carbonization of wool), disordered and transversely closely-connected fibers are processed into longitudinally-sequentially arranged smooth yarns with certain requirements, massive fibers need to be changed into single fiber states, the transverse connection existing in the fiber raw materials is removed, and firm end-to-end longitudinal connection is established. The former is called the debonding of fibers and the latter is called the collecting of fibers. The loosening of the fibers is a complete removal of the cross-directional connections that exist between fibers, but the damage to the fibers must be minimized. The aggregation of the fibers is such that the debonded fibers reestablish an ordered longitudinal relationship that is continuous and that provides uniform fiber distribution within the aggregate and at the same time a certain linear density and strength. The fiber assembly also needs to be added with a certain twist. The gathering process is not finished once, and can be finished through multiple processing such as carding, drafting, twisting and the like, and the opening is to tear large fibers into small fiber bundles. As the opening action progresses, the connection between the fibers and the impurities is weakened, so that the impurities are removed and the fibers are mixed. The opening and impurity removal is not completed once, but is realized gradually through reasonable configuration of tearing, striking, dividing and the like, and the carding function is to further loosen small fiber blocks and small fiber bundles into a single state through a large number of dense carding needles on a carding machine, so that the fiber loosening is further completed. After carding, the transverse connection between the fibers is basically released, and the functions of impurity removal and mixing are more sufficient. However, a large number of fibers are bent and have hooks, and each fiber still has a certain transverse connection. In the earliest spinning machines, the combing function of the combing machine was to perform finer combing in a state where both ends of the fibers were held by the combing needles. The processing of the combing machine can eliminate short fibers and fine miscellaneous defects below a certain length, and promote the fibers to be more parallel and straight. The chemical fiber has regular length, less impurities and good straightening and parallel state, so that the carded sliver is drawn and thinned to gradually reach the preset thickness without being processed by a combing machine. And a foundation is laid for firmly establishing regular head-to-tail connection relation among fibers. However, drafting causes uneven short segments of the sliver, so that reasonable drafting devices and process parameters need to be configured, twisting is performed to twist the sliver around the axis of the sliver, so that fibers parallel to the axial direction of the sliver are in a spiral shape, radial pressure is generated to fix the longitudinal relation between the fibers, and the semi-finished product or the finished product is wound into a certain form so as to be convenient for storage, transportation and processing of the next procedure. The winding process should be continuously performed without affecting the yield and quality of the product, and efforts should be made to achieve continuous production between the processes and to minimize the quality problems caused by the winding process. The spinning process generally comprises the actions of raw material preparation, opening, carding, impurity removal, mixing, drafting, merging, twisting, winding and the like, and some actions are realized through repeated times.
It is to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
