Problems solved by technology

Narrow film tape material gives fabric bags the desired breathability or openness, however, the rough edges of the tape give a rough feel to the touch which may damage more delicate perishable produce
Furthermore, due to the slippery nature of the narrow film tape, the dimensional stability of the fabric is impaired, so that the bag does not retain its shape during handling
[0003] Further, in order to improve the softness of the fabric and resulting bags, if only multifilament yarns are used in the manufacture of leno bags, there are more dimensional stability issues during bag processing, goods packaging and bag storage

Embodiment Construction

[0027] Woven fabrics generally include a warp structure and a weft structure formed using warp threads and weft threads, respectively. Woven tape fabrics typically include two sets of threads arranged in a warp structure and a weft structure. Yarns are typically made from multiple narrow film strips. The yarns of any one group (warp structure or weft structure) are arranged parallel to each other and interweaved with the yarns of the second group (weft structure or warp structure). The yarns of one set are generally oriented at right angles to the yarns of the other set. For a simple plain weave, the warp threads pass over and under the weft threads in an alternating pattern. Specifically, for a given warp thread to pass over a particular weft thread, an adjacent warp thread will pass under that particular weft thread, thereby locking the weft thread in place. A limitation of plain weave is the lack of porosity or openness.

[0028] A typical leno weave is different from a...

Abstract

This invention relates to producing bags for packing and storing of goods. More particularly, the invention relates to flat or tubular leno weave fabric which is comprised of at least one warp thread (6A) that has one of its strands (6B or 6C) made from bulk yarn as weft and / or at least one of its weft threads (5A) is made from bulk yarn, and a bag made from such fabric. The invention addresses the problem of harshness of the leno weave fabric made from stiff yarn, particularly on perishable goods and other goods that can get damaged by harsh packaging. Woven fabrics typically comprise warp and weft structures that formed using warp and weft threads, respectively. Woven slit film tape fabric typically comprises of two sets of threads arranged in warp structure and weft structure. Threads are typically made of multiple slit film tapes. The fabric of the invention has some bulk yarn introduced in the weaving pattern to make the fabric softer than the conventional fabric. This key aspect of the invention has led to bags that are less harsh on the goods, than bags made from conventional leno fabric made from stiff yarn.

Description

technical field [0001] This invention relates to the production of bags for packaging and storing goods. More specifically, the present invention relates to packaging and storing perishable agricultural products (farm products). More particularly, the present invention relates to bags made from flat or tubular fabrics composed of at least one bulky yarn as weft yarns and at least one bulky yarn as warp yarns in combination with hard yarns Composition in which the weft yarns are held in place against each other by leno weaving. Background technique [0002] Typically, open mesh leno bags used to pack different agricultural products such as potatoes, onions, fruits, flowers, etc. are made of narrow film strips of polyethylene or polypropylene material. The narrow film tape material gives the desired breathability or openness to the fabric bag, however, the rough edges of the tape give a rough feel to the touch, which can damage more delicate perishable produce. Furthermore,...
