Abstract

A technology for weaving cotton-plastics bags on circular loom includes ginning leftover of cotton cloth, spinning, doubling, winding, doubling yarn, rolling, forming weft bobbin and weaving, and features full use of waste, and high quality of product.

Description

Circular loom processing cotton is moulded woven bag technology

The present invention relates to weaving method, particularly circular loom processing cotton is moulded woven bag technology.

The woven bag of processing generally was a Polywoven Bag on circular loom in the past, and warp of this bag and parallel all are plastic flat fibers.Plastic flat fiber is a raw material by polypropylene, and through the extruder wire-drawing process, the wire drawing chopping becomes wide 1.6～1.9mm, thickness 0.04～0.05mm, winder, warping, network are through passing on circular loom then, and the warp total number is 600～700, and above-mentioned is through the bar preparatory technology; Remake the weft yarn preparatory technology then, through weaving on the circular loom, at the bottom of cutting out bag, bagging, bagging mouth, finished product purchase to receive and be Polywoven Bag, according to the length specification of the bar number decision sack of parallel.Because the heap height easily skids the easy bale broken of transporting for long-distance during the Polywoven Bag Bale Cargo.

The purpose of this invention is to provide on circular loom the processing cotton and mould woven bag technology, warp remains plastic flat fiber, and parallel adopts the regeneration cotton yarn, makes full use of waste cotton cloth angle material, is made into cotton and moulds woven bag.

The present invention finishes as follows: change weft yarn preparatory technology on the circular loom into a waste cotton cloth leftover ginning, and---------------be rolled into the yarn tube---making the parallel spool---is woven into cotton and moulds woven bag on circular loom to piece together yarn on the yarn-splicing machine to be rolled into the yarn dish to piece together line in spinning.

Spinning count is 8 behind the said cloth leftover ginning, be combined into 1 with 2 yarns when piecing together line, it is Φ 30mm that the regeneration cotton yarn that will be combined into then is rolled into diameter, thickness is 5～6 centimeters yarn dish, on yarn-splicing machine, be combined into one by 2 cotton yarns again, it is spun into a yarn, the parallel spool of making its shape such as spindle like or turriform or doleiform again weaves on circular loom again.

It is 500～600 that said cotton is moulded woven bag parallel total number.

Advantage of the present invention is because the employing parallel is the regeneration cotton yarn, can make full use of waste cotton cloth angle material, twice laid, heap is high non-slip in the time of can making cotton mould the woven bag Bale Cargo in addition, is difficult for bale broken during transportation, and because water imbibition is arranged, can prolong the packing material shelf-life, replace the bale packing transportation, the weight ratio gunnysack is light, price is lower than gunnysack, and better than Polywoven Bag intensity.Be widely used in the packed and transported of graininess, powdered goods.Adopt the history that this process reform can only the processing plastic woven bag on circular loom, and the output height, quality is good.

Further describe below in conjunction with process chart.

Fig. 1 is that circular loom processing cotton is moulded the woven bag process chart.

With reference to Fig. 1, prepare through bar: plastic pellet is generally polypropylene, polyethylene, its fusion on extruder is added hot-extrudable, the wire drawing chopping becomes wide 1.6～1.9mm, the flat filament of thickness 0.04～0.05mm, winder, warping, network are through passing then, and woven bag warp total number is 600～700.

Weft yarn preparatory technology: at first waste cotton cloth leftover ginning, spinning is secondary 8 then, article 2, yarn is pieced together line, is rolled into the yarn dish again, yarn dish diameter of phi 30mm, 5～6 centimeters of thickness, again on yarn-splicing machine 2 be combined into one, be spun into a yarn, remake the parallel spool and on circular loom, weave, because the tensile strength of cotton yarn is different from plastic flat fiber, so circular loom should be made adaptation and can process.The shape of parallel spool such as spindle like or turriform or doleiform.Weave on circular loom then, the total number of parallel is 500～600.

General quilling mode is taken out the limit type for the clockwise intersection of pipe is arranged, and single latitude net weight is 65 ± 5 grams, and every little latitude external diameter is Φ 3.1cm, and length is 20cm, the disconnected latitude junction type that changes: weaver's knot, ending length 5～10mm.Thread count is 55 * 48/10 centimetres in the weaving process, requires evenly.The continuous tubular cotton that circular loom processes is moulded woven bag, needs to cut out bag by dimensional requirement, then at the bottom of the bagging, sew up on machine at the bottom of the lock stitch, per 10 centimetres of seam 9 pins are at the bottom of the polypropylene fibre linear slit, and sack also need be made, and end product is checked and accepted, and finishes the processing technology that cotton is moulded woven bag.

Claims

1. circular loom processing cotton is moulded woven bag technology, warp is raw material with the polypropylene plastics, through the extruder wire-drawing process, the wire drawing chopping becomes wide 1.6～1.9mm, the flat filament of thickness 0.04～0.05mm, then winder, warping, network through, pass, on circular loom, 600～700 of warp total numbers more than are through the bar preparatory technology; Remake the weft yarn preparatory technology then, weave through on the circular loom, at the bottom of cutting out bag, bagging, bagging mouth, finished product check and accept and mould woven bag for cotton, it is characterized in that: said weft yarn preparatory technology is a waste cotton cloth leftover ginning, and------------------making the parallel spool---weaves on circular loom to be rolled into the yarn tube to piece together yarn on the yarn-splicing machine to be rolled into the yarn dish to piece together line in spinning.

2. mould woven bag technology according to the said circular loom processing of claim 1 cotton, it is characterized in that spinning count is 8 behind the cloth leftover ginning, be combined into one with 2 yarns when piecing together line, it is Φ 30mm that the regeneration cotton yarn that will be combined into then is rolled into diameter, thickness is 5～6 centimeters yarn dish, be combined into one by 2 cotton yarns on yarn-splicing machine again, it be spun into a yarn again, the parallel spool of making its shape such as spindle like or turriform or doleiform again weaves on circular loom.

3. mould woven bag technology according to claim 1 or 2 said circular loom processing cottons, it is characterized in that it is 500～600 that cotton is moulded woven bag parallel total number.
