Production technology of zipper cloth tape

Abstract

The invention discloses a production technology of a zipper cloth tape. The production technology comprises a cloth tape setting process, wherein the cloth tape setting process comprises the following steps: penetrating a to-be-set cloth tape on a setting machine in advance, carrying out semi-tensioning pretreatment on the to-be-set cloth tape, starting the setting machine, continuously feeding the to-be-set cloth tape into a setting chamber of the setting machine in a semi-tensioning state by using a tension constant control device driven by a first motor; enabling the to-be-set cloth tape to be in a semi-tensioning relaxed state between upper and lower rows of rollers in the setting chamber, and carrying out up-and-down alternately continuous and slow forward setting movement to a tape outlet direction of the setting chamber, so as to obtain the set cloth tape with the shrinking percentage of 1%-7%; and controlling the rotating speeds of the motors, and enabling the set cloth tape to reach the required shrinking percentage. According to the production technology, the cloth tape is shrunk in set in advance, so that the shrinkage amount is reduced in subsequent dyeing process, and further cloth tape indentation is prevented; the color difference of a zipper among the upper layer, the middle layer and the lower layer in the dyeing process is avoided; and the cloth tape dyeing uniformity is improved.

Description

technical field [0001] The invention belongs to the field of zipper production, in particular to a zipper tape production process. Background technique [0002] At present, the production process of zipper tape mainly includes the following procedures: Ribbon (weave the tapes on both sides of the zipper), sorting (arranging the woven tape in an orderly manner), shaping (setting the cloth tape), tape (weaving the cloth The tape is rolled on the bobbin to become a cloth tape roll), dyeing (rolling the rolled cloth tape into a dyeing vat for dyeing), drying (drying the dyed cloth tape). According to different types of zippers, some different production procedures will be added. [0003] Among them, in the production process of zipper tape, the dyeing process is usually taken as the main process of tape shrinkage. Specifically, in the process of dyeing the cloth tape roll, the cloth tape is generally made of polyester material. Due to the characteristics of the material itself...
