Problems solved by technology

Traditional bandages need buckles, which are fixed by adhesive tape, which is inconvenient to use, and at the same time, it is easy to disengage, and the fixing effect is not ideal; as for adhesive bandages, most of the bandages on the market currently use pressure-sensitive adhesives, adhesive plasters, etc. , these bandages are too viscous and have poor air permeability, and it is easy to cause further damage to the skin when opened; and the protective bandages are too cumbersome to use because of their too many size requirements and varying degrees of tightness.

Embodiment 1

[0014] Embodiment 1: the manufacture method of non-woven adhesive elastic bandage, concrete steps are as follows:

[0015] 1) Select two rolls of polypropylene non-woven fabric with a weight of 8g per square meter, both of which are 500 meters in length and 1.1 meters in width.

[0016] 2) Choose 20 rolls of spandex yarn with an elasticity of 70D.

[0017] 3), synthetic adhesive 10kg, the adhesive quality formula is as follows: solid rubber 5-10kg, ethyl acetate 15-20kg, sodium benzoate 10-20g, butyl propionate 10-20g.

[0018] 4) Put a roll of the material in step 1) on the front feeding rack, put the adhesive in the funnel, and use the scraping method to evenly apply the adhesive to the top of the non-woven fabric.

[0019] 5), pass the 20 rolls of spandex yarns in step 2) through 20 positioning holes, the distance between the positioning holes is 5mm, and produce a row of neatly arranged spandex yarn warps.

[0020] 6), fix another roll of non-woven fabric in step 1) on t...

Embodiment 2

[0029] Embodiment 2: the manufacture method of cotton cloth and nonwoven composite adhesive elastic bandage, concrete steps are as follows:

[0030] 1) Choose a roll of polypropylene non-woven fabric with a weight of 8g per square meter, a length of 500 meters and a width of 1.1 meters, and a roll of warp and weft woven cotton cloth with a weight of 50g per square meter, a length of 500 meters and a width of 1.1 meters. Meter.

[0031] 2), select 20 rolls of spandex yarn with elasticity of 100D.

[0032] 3), synthetic adhesive 10kg. The quality formula of the adhesive is as follows: 5-10kg of natural latex, 2-3kg of white oil, 0.5-1kg of white oil emulsifier, 10-20g of sodium benzoate, and 10-20g of butyl propionate.

[0033] 4) Put a roll of the material in step 1) on the front feeding rack, put the adhesive in the funnel, and use the scraping method to evenly apply the adhesive to the top of the non-woven fabric.

[0034] 5), pass the 20 rolls of spandex yarns in step 2) ...

Abstract

The invention relates to a making method of an adhesive elastic bandage, comprising steps of: 1) daubing a layer of adhesive agent on an inelastic backing cloth material; 2) arranging spandex threads in longitude direction, and layering them on the backing cloth material; 3) overlaying another layer of backing cloth material on the top layer; 4) extruding each layers in step 1), 2), and 3), to imbed the spandex threads between the two layers of backing cloth materials; 5) drying the composite backing material formed in step 4) by using baking oven, to make the two layers of inelastic backing cloth materials formed into elastic backing cloth composite material via compounding of adhesive agent and spandex threads; 6) fully immersing into adhesive agent, daubing a layer of composite adhesive agent on the backing cloth material, extruding and drying for a second time, and thus forming elastic adhesive cloth. The invention has the beneficial effects of self-adhesion, no adhesion to other things, good ductility, high tension stress, free of lock seaming, good air permeability, moderate self-adhesiveness, easy opening, arbitrary fixing, free of falling-off, and arbitrary tearing.

Description

technical field [0001] The invention relates to a medical bandage, mainly a method for making an adhesive elastic bandage. Background technique [0002] Currently on the market, most of the soft fixations are traditional bandages, gauze, viscose bandages and protective belts such as waist guards, knee pads, wrist guards, etc.). Traditional bandages need buckles, which are fixed by adhesive tape, which is inconvenient to use, and at the same time, it is easy to disengage, and the fixing effect is not ideal; as for adhesive bandages, most of the bandages on the market currently use pressure-sensitive adhesives, adhesive plasters and other highly viscous bandages. , These bandages are too viscous and have poor air permeability, and they are easy to cause further damage to the skin when opened; and the protective belts are too sizing due to their size requirements, varying in elasticity, and cumbersome to use at the same time. ...
