Abstract

The utility model relates to a glass no-twist fibre with adhesive, which can be used for the packing bag of complex cement. The glass no-twist fibre with adhesive comprises a glass fibre bundle made from multi-strand glass basic yarns (1) without twisting, and one layer of adhesive (2) without drying of the glass fibre bundle. The glass no-twist fibre with adhesive can be twisted to a cylinder yarn or a spindle yarn. The glass fibre bundle can be polymerized together by the adhesive effect of the adhesive. The utility model can not emanate, fracture and fluff. The adhesive can play good lubrication action in the process of high velocity winding of making bag.

Description

Glass no-twist fibre with adhesive

The utility model relates to the structure of the glass zero twisted yarn that a kind of complex cement packaging bag uses.

Use two layers of brown paper, the cement packing complex pocket that middle compound one deck natural fabric or plastic wire reinforcing material are made, the tensile strength height, breakage rate is low, has saved paper again.Chinese patent 87215557.9 has been introduced and has a kind ofly been done reinforcement with the glass zero twisted yarn, adopt and twine the cement packing complex pocket that technology into the net is made, because glass fibre tensile strength is high especially, and the source is abundant, cheap, the cement package bags intensity height of making, breakage rate is low, and low price has very strong competitiveness.But glass fibre is compared with natural fabric, synthetic fiber, and fragility is big, not anti-bending, and cohesive force was little between fiber surface was smooth, mutual.When producing continuous glass zero twisted yarn, after operations such as coiling, Split Down, doff, one-tenth tube, there are broken yarn, wool yarn in the tube yarn, loose yarn and a group's yarn, be to produce cause faults in the high speed winding process when making complex pocket.

The purpose of this utility model is the structure that proposes a kind of glass zero twisted yarn, can overcome above-mentioned disadvantage.

The glass zero twisted yarn of this band adhesive comprises by multiply glass raw yarn without twisting, and closes the ORGANDY fibre bundle that forms, and scribbles the not adhesive of drying of one deck on glass fiber bundle.

The glass zero twisted yarn of this band adhesive all has adhesive between the surface of glass fiber bundle and the fiber, because the adhesive effect of adhesive condenses together glass fibre, can not disperse, not easy fracture and fluffing.In the high speed winding process of making complex pocket, the adhesive on surface can also play good lubrication, does not produce or seldom produce broken end.The glass zero twisted yarn of this band adhesive can be removed original broken yarn, group's yarn in the gluing process with the method for manual sorting, wool yarn and diffusing yarn are understood automatically and fibre bundle fits together.But the glass zero twisted yarn coiled tube yarn of this band adhesive or the yarn that splits are used for bag.As long as enough big pitch is arranged when becoming tin, for example pitch is greater than 6cm, just can guarantee not stick together moving back when separating, and can agglomeratingly not come off moving back when separating and the viscosity of the adhesive on glass fiber yarn surface can also guarantee a yarn.

Accompanying drawing is the structure chart of the glass zero twisted yarn of this band adhesive.

(1) is glass fibre among the figure, and (2) are the adhesive of drying not.

Adhesive on the glass zero twisted yarn of this band adhesive can be the mixture etc. of graft copolymer, starch and the rubber latex of starch size, starch and acrylamide, with water miscible elastic adhesive for well.Water-soluble is to be convenient to recycling for the paper that makes complex pocket, and elasticity then can increase the flexibility of ORGANDY, thereby improves fracture resistance.

The JSF stick of low acetalizing degree is exactly a kind of proper water-soluble elastic attachment adhesive, can make as the aldolisation catalyst with phosphoric acid.The example of making of low acetalizing degree JSF stick:

Example one: polyvinyl alcohol 100 parts (weight) adds in 600 parts of water, is heated in water-bath about 96 ℃, treat that polyvinyl alcohol dissolves fully after, be cooled to 50-60 ℃, add 00 part of phosphatase 11, be incubated half an hour, add 30 parts of 37% formalins, aldolisation 1-2 hour, add 10 parts of 20% aqueous solution of urea again,, free formaldehyde is reduced to below 0.2% with the not free formaldehyde of acetalation reaction about 1 hour in the glue, be cooled to normal temperature, add 10 parts of glycerol.Above operating process is all under agitation carried out.

Example two: 100 parts of polyvinyl alcohol, add in 600 parts of water, in water-bath, be heated to about 96 ℃, after treating that polyvinyl alcohol dissolves fully, cool to about 50 ℃, add 80 parts of phosphoric acid, be incubated half an hour, add 10 parts of butyraldehyde, under 40-50 ℃ of temperature aldolisation 2-3 hour, add 10 parts of 20% aqueous solution of urea again, reacted about one hour, free butyraldehyde in the glue is dropped to below 0.2%, be cooled to normal temperature, add 10 parts of ethylene glycol.More than the operation overall process is all under agitation carried out.

This water miscible elastic adhesive also can be to be the polyvinyl alcohol adhesive of plasticizer with phosphoric acid.Can prepare in the following method.

100 parts of polyvinyl alcohol add in 600 parts of water, are heated in water-bath about 96 ℃, treat that polyvinyl alcohol dissolves fully after, be cooled to 40-50 ℃.Add 20 parts of phosphatase 11s, be incubated half an hour, reduce to normal temperature again, add 10 parts of glycerol, 10 parts of ethylene glycol.More than the operation overall process is all under agitation carried out.

The glass zero twisted yarn adhesive coating that the adhesive that adopts above-mentioned technology to obtain is made, viscosity between the 1200-1400 centipoise, solid content about 25%, glued membrane softness, high resilience, percentage elongation is more than 300%.
