The textile process includes spinning process and weaving process.
The spinning process mainly includes: cleaning, carding, combing, drawing, roving, and spun yarn.
The weaving process mainly includes: winding, warping, sizing, drawing-in, weaving and finishing.
1. Main equipment and tasks of the spinning process:
1. Cotton cleaning process: remove most impurities, defects and short fibers that are not suitable for spinning in raw cotton.
2. Carding machine: The cotton rolls coming out of the cleaning process go through the processes of licker-in roller, cylinder cover, doffer and other processes.
Carding, removing impurities, mixing into slivers and putting them into the tube.
3. Combing process:
Commer:
1) Impurity removal: remove neps, impurities and fiber defects in the fiber.
2) Carding: further separate fibers and exclude short fibers below a certain length.
3) Drafting: thinning the cotton sliver to a certain thickness and increasing the parallel straightness of the fibers.
4. Drawing process:
Drawing machine:
1) Merging: Use 6 to 8 cotton slivers to merge and improve the sliver Long segments are uneven.
2) Drafting: Elongate and thin the cotton sliver to a specified weight, and further increase the straightness and parallelism of the fibers.
3) Mixing: Using combining and drafting, the slivers are mixed on the draw frame according to the process.
4) Forming into slivers: Make the coiled slivers into well-formed cooked slivers, and place them regularly in the sliver can.
5. Roving process:
Roving frame: The drawn sliver is drawn and twisted to make the yarn have a certain strength to facilitate the roving winding. And it helps the yarn unwinding on the spinning machine.
6. Spinning process:
Spinning frame: Draw and thin the roving to the required fineness and twist it to form a spun yarn with a certain twist and strength and wind it around on the bobbin.
2. Main equipment and tasks of the weaving process:
1. Winding process:
Winder: is the bobbin that is taken up and down from the twisting machine Rewinding into a bobbin with a certain shape and large capacity, while eliminating impurities and defects on the yarn, thereby improving the productivity of subsequent processes.
2. Warping process:
Warping machine: According to the process design requirements, a certain number of warp yarns are pressed into the specified length and width under the action of a certain tension. Parallel wound on the warp beam.
3. Sizing process:
Sizing machine: In order to bond the single fibers of the silk to each other and increase the breaking strength of the silk, it will facilitate smooth weaving on the machine. Put the completed warp beam on the sizing machine, suck the pulp, and dry it in the oven.
4. Drawing-in process:
Drawing-in machine: Thread each warp yarn on the warp beam into the healds and reeds in a certain order according to the process design requirements. And insert the warp drop piece on the warp yarn to confirm that everything goes smoothly in the weaving process.
5. Weaving process:
Shuttle loom: The warp beam is guided through the shuttle weft yarn on the shuttle loom, interwoven into gray cloth according to the process requirements, and wound into cloth rolls.
