Abstract

The utility model discloses a high-strength sewing structure of a polyester fiber ribbon, which comprises an intersecting sewing structure, a crease structure and a lap sewing structure, wherein the intersecting sewing structure, the crease structure and the lap sewing structure are sewn by adopting aramid fiber line-bonding zigzag stitch; the cross stitching structure: two polyester silk belts are crossed, and the intersection of the woven belts is sewed by combining aramid fiber yarns with N rows of saw teeth; the crease structure: the end of one polyester fiber ribbon is folded in half, and the folded part of the ribbon is sewn by combining aramid fiber wires with N rows of saw teeth; the lap joint structure comprises: the two polyester silk belts are aligned and overlapped, and the overlapping part of the woven belts is sewed by combining aramid fiber lines with N rows of saw teeth. The utility model improves the stitching strength of the polyester silk ribbon stitching part.

Description

High-strength sewing structure of polyester fiber ribbon

Technical Field

The utility model belongs to the technical field of sewing of polyester fiber belts, and particularly relates to a sewing method of an aramid fiber wire combined sawtooth-shaped linear yarn to a polyester fiber belt.

Background

At present, most of the polyester silk yarns or nylon silk yarns are used for stitching, and generally square-shaped linear yarns, three-point crossed linear yarns or four-point crossed linear yarns are used as stitching yarns, so that the strength of the polyester silk yarns and the nylon silk yarns after stitching is not ideal due to low breaking strength of the polyester silk yarns and the nylon silk yarns.

Disclosure of Invention

The utility model aims to provide a high-strength sewing structure of a polyester silk ribbon.

The technical solution for realizing the purpose of the utility model is as follows: a high-strength sewing structure of polyester fiber ribbon comprises a cross sewing structure, a crease structure and a lap sewing structure, which are all sewn by adopting aramid fiber line to combine zigzag stitch.

The cross stitching structure: the two polyester silk belts are crossed, and the intersection of the woven belts is sewed by combining aramid fiber yarns with N rows of saw teeth.

The crease structure: the end of one polyester fiber ribbon is folded in half, and the folded part of the ribbon is sewn by combining aramid fiber wires with N rows of saw teeth.

The lap joint structure comprises: the two polyester silk belts are aligned and overlapped, and the overlapping part of the woven belt is sewed by combining aramid fiber lines with N rows of saw teeth

Compared with the prior art, the utility model has the remarkable advantages that: (1) According to the utility model, the polyester fiber ribbon is sewn by adopting the aramid fiber thread combined with the sawtooth stitch, so that the sewing strength of the polyester fiber ribbon is improved. In the adoption of the stitch and sewing mode, the breaking strength of the aramid yarn is obviously higher than that of the nylon yarn and the polyester yarn, but because the elongation of the aramid yarn is lower, the problem that the elongation of the stitch is not matched with the elongation of the woven belt is solved by adopting the aramid yarn to combine the zigzag stitch for sewing. (2) Compared with the traditional sewing mode of combining nylon threads or polyester threads with square stitching or three-point cross stitching, the aramid thread combined zigzag stitching can enable the stitching part to obtain larger binding force, and enable the stitching part to be higher in strength.

Drawings

FIG. 1 is a cross stitch of a 7# aramid yarn combined with six pairs of zigzag stitches 47-2700A polyester yarn.

FIG. 2 is a chart of 7# aramid yarn stitch bonded six rows of zigzag stitch pairs 47-2700A polyester ribbon crease stitching.

FIG. 3 is a lap seam stitch of a 7# aramid yarn combined with six rows of zigzag stitch pairs 47-2700A polyester yarn strip.

Detailed Description

The utility model is further described below with reference to the drawings and examples.

A high-strength sewing structure of polyester fiber ribbon is specifically sewn by adopting aramid fiber thread to combine zigzag stitch. The polyester fiber ribbons may be cross-stitched (see fig. 1), or creased (see fig. 2), or may be lap-stitched (see fig. 3). When in sewing, the thickness of the aramid fiber thread can be selected according to the thickness of the polyester fiber tape, and the corresponding number of sawtooth lines can be selected according to the width of the polyester fiber tape.

Cross stitching: as shown in FIG. 1, two 47-2700A polyester tapes are crossed, and the crossed part of the tapes is sewn by combining six rows of saw teeth with 7# aramid thread.

Crease lines: as shown in FIG. 2, the end of a piece of 47-2700A polyester fiber ribbon is folded in half, and six rows of saw teeth are used for sewing the folded part of the ribbon by using a 7# aramid fiber wire.

And (3) lapping: as shown in FIG. 3, the two 47-2700A polyester tapes are aligned and overlapped with each other, and the overlapped part of the woven tape is sewn by six rows of saw teeth with a 7# aramid thread.
