Embodiment 2

[0042] A woven bag, woven through the following process: using flat yarn as raw material, dividing the flat yarn into vertical warp flat yarn and horizontal weft flat yarn, weaving warp flat yarn and weft flat yarn to obtain weaving Cloth, the woven cloth can be cut into a certain length and width and then sewn into a woven bag. The width of the warp flat yarn is smaller than the width of the weft flat yarn.

[0043] The weaving density of the warp flat yarns and weft flat yarns is that the ratio of the number of warp flat yarns to the number of weft flat yarns per unit area of ​​10cm*10cm is 49-50:40-41.

[0044] The width ratio of the warp flat yarn and the weft flat yarn is 1.80:2.40, the width of the warp flat yarn is 1.80mm, and the width of the weft flat yarn is 2.40mm.

[0045] Described flat silk comprises the raw material of following weight percent:

[0046] Masterbatch 15%

[0047] PP 75%

[0048] Recycled 10%.

[0049] The masterbatch is prepared by the followi...

Embodiment 3

[0054] A woven bag, woven through the following process: using flat yarn as raw material, dividing the flat yarn into vertical warp flat yarn and horizontal weft flat yarn, weaving warp flat yarn and weft flat yarn to obtain weaving Cloth, the woven cloth can be cut into a certain length and width and then sewn into a woven bag. The width of the warp flat yarn is smaller than the width of the weft flat yarn.

[0055] The weaving density of the warp flat yarns and weft flat yarns is that the ratio of the number of warp flat yarns to the number of weft flat yarns in a unit area of ​​10cm*10cm is 49-50:39-40.

[0056] The width ratio of the warp flat yarn and the weft flat yarn is 1.95:2.45, the width of the warp flat yarn is 1.95mm, and the width of the weft flat yarn is 2.45mm.

Abstract

The invention relates to the technical field of packaging materials, in particular to a woven bag and its weaving process, the woven bag includes a plurality of weft flat wires arranged in parallel and a plurality of warp flat wires arranged perpendicularly to the weft flat wires , the width of the warp flat yarn is smaller than the width of the weft flat yarn. In the woven bag of the present invention, the width of the warp flat yarn is smaller than the width of the weft flat yarn, so that the surface cloth surface of the woven bag is good and the surface is smooth, and at the same time, the warp flat yarn and the weft flat yarn can be discounted during the weaving process. Problems, to further ensure the surface effect of woven bags, greatly improving the current situation of rough surface of existing woven bags.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a woven bag and a weaving process thereof. Background technique [0002] The existing woven bags generally have the following problems: the surface cloth effect is poor, the surface is rough, and the situation that the warp flat yarn is often discounted occurs. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a woven bag with smooth surface and good cloth surface effect. [0004] Another object of the present invention is to provide a weaving process for woven bags, which has high weaving efficiency and no warp flat yarn folds, and the woven bag has a good surface cloth effect. [0005] The purpose of the present invention is achieved through the following technical solutions: a woven bag, which includes a plurality of parallel parallel arranged weft flat wi...
