Description

Heating device for preparing super flat plastic woven cylinder cloth and preparation method

Technical Field

The application relates to the technical field of plastic woven cylinder cloth production, in particular to a preparation method of heat-setting super-flat plastic woven cylinder cloth.

Background

The plastic woven cylinder cloth is a packaging article manufactured by using warp yarns and weft yarns with certain specifications on a plastic woven circular loom according to certain reed density, has wide application range, and particularly takes absolute predominance in the application of the material packaging industry. With the increasing packaging demands of high-end materials, such as food-grade materials, the quality requirements on the plastic woven cylinder cloth are higher and higher, and particularly the surface flatness of the plastic woven cylinder cloth is required.

In the related art, a plastic woven circular loom comprises a loom body and a cylindrical cloth winding mechanism, wherein woven plastic woven cylindrical cloth is output by the loom body and is wound by the cylindrical cloth winding mechanism. The plastic knitting circular loom adopts a mode that a yarn feeding frame freely unwinds and sends warp and weft, and a shuttle ship unwinds and sends weft to the loom. The weft yarn is fed through the yarn feeding frame or the shuttle boat, and the weft yarn is drawn through the circular loom so that the yarn tube on the yarn tube frame rotates and the yarn tube on the yarn tube is discharged.

As the tube filament is paid out, the winding diameter on the filament tube will change accordingly, resulting in a large difference in the weight of the tube filament stored on the filament tube, while the gravitational retarding force experienced by the filaments will change as the tube filament is paid out. The circular loom applies the same single filament traction force on the tube filament, the tube filament is stretched by a dynamic change of tension under the action of the single filament traction force and the gravity retarding force which is changed continuously, and internal stress with great difference is generated on each single filament because of the gravity retarding force which is changed continuously and the inherent plastic rebound resilience of the plastic tube filament. The internal stress is positively related to the weight of the tube wire on the wire tube, the gravity retarding force of the tube wire newly put on the tube wire frame is maximum, the elongation of the single wire is maximum, the retraction possibility is also maximum, and the internal stress of the single wire is also maximum. Conversely, the gravity blocking force of the pipe wire to be wound is minimum, and the possibility of retraction of the single wire and the internal stress are minimum.

The internal stress of the monofilaments is distributed and changed in a discrete type freely due to the change of the winding diameter of the tube filaments, and the difference finally causes great difference of the internal stress of each monofilament among the warp filaments and among the weft filaments after the warp filaments and the weft filaments are woven into the plastic woven cylinder cloth, so that the retraction amount of each monofilament is greatly different. Because of the difference of the retraction amounts, the plastic woven cylindrical fabric is uneven, and the plastic woven cylindrical fabric is not parallel left and right when serious.
