Definitions
- the invention relates to a process for flameproofing textiles.
- An object of the present invention is to provide a flameproofing process for cellulose textiles which will not materially crease or shrink the fabric.
- Another object of the invention is to provide a process for flameproofing cellulose textiles which can be used in the cleaning machines ordinarily used in chemical cleaning, and may be preceded with or followed with chemical cleaning or the cleaning may take place simultaneously, in the same machine.
- Another object is to provide a substantially anhydrous flameproofing concentrate which when mixed with substantially anhydrous solvents used in the preparation of the fiameproofing baths will give a substantially clear solution which will not tend to crease and shrink already made up cellulose textiles.
- the present invention therefore, provides an impregnating bath medium, for flameproofing cellulose textiles, comprising a mixture of a substantially anhydrous zinc chloride in a lower alcohol, glycol or carboxylic acid ester and an organic solvent utilizable for chemical cleaning.
- the bath medium should be substantially anhydrous, having a low water content in the entire bath composition.
- the process for flameproofing textiles which consist wholly or substantially of cellulose or regenerated cellulose fibres provided herein, comprises contacting said textiles with a bath medium comprising a mixture of a concentrated substantially anhydrous solution of zinc chloride in a lower alcohol, glycol or carboxylic acid ester and a substantially anhydrous organic solvent utilizable for chemical cleaning.
- a concentrated stock solution is first made by dissolving zinc chloride in an anhydrous lower alcohol or glycol containing 2 to 4 carbon atoms, such as ethanol, propanol, isopropanol, butanol, ethylene glycol, 1,3- or 1,3- propylene glycols and the like.
- anhydrous lower alcohol or glycol containing 2 to 4 carbon atoms such as ethanol, propanol, isopropanol, butanol, ethylene glycol, 1,3- or 1,3- propylene glycols and the like.
- suitable solvents are esters of the said alcohols with monocarboxylic acids which contain 1 to 4 carbon atoms, as for example, ethyl acetate, the monoglycol ester of propionic acid and the like.
- concentrates contain 5 to 35% by weight of anhydrous zinc chloride, which may consist either of products of technical purity with the lowest possible content of coloring or sludge-forming impurities, or if desired products of high purity, for example, corresponding to the German harmacopoeia quality DAB 6.
- the impregnating liquors consist of the solvents utilized in chemical cleaning, especially petroleum hydrocarbons of boiling points of to 200 and halogenated hydrocarbons having 1 to 4 carbon atoms such as methylene chloride, carbon tetrachloride, perchlorethylene, trifluorotrichloroethane, monofiuorotrichloromethane, etc.
- the process is eifected preferably in the cleaning machines used in chemical cleaning, suitably following a chemical cleaning.
- the textiles are treated with the impregnant medium at 2 0 to 35 C. for 2 to 10 minutes and after centrifuging and drying are ready for use.
- very good flameproofing efiects can be at tained which correspond to the DIN specifications 53,906 and 53,907.
- an application of 0.8 to 8% by weight of zinc chloride, based on the weight of the fibre, is needed.
- organic fiameproofing agents provided they are soluble in the impregnating liquors, may be added to the baths.
- halogenated parafiins especially chlorinated paraflins, which simultaneously exert a specific softening action on the textile fibre, are suitable for this purpose.
- These ingredients are added to the baths in amounts of from 3 to 20 g. per liter.
- further additions customary in textile finishing may also be present, such as brightening agents, waterproofing agents, dressing agents or agents producing a high finish, for example, urea or melamine-formaldehyde condensation products and the like.
- EXAMPLE 1 In a cleaning machine of the Biiwe R 9 M type, 6 kg. of curtains, consisting of rayon staple fibre rep, were cleaned as usual and then treated for 5 minutes in 60 liters of perchlorethylene with the addition of 10 liters of butyl acetate in which 12% by weight of anhydrous zinc chloride was dissolved. The textiles so treated, after centrifuging and drying in the cleaning machine, were difficultly inflammable, in contrast to untreated curtains.
- EXAMPLE 2 In the cleaning machine used in Example 1, 8 kg. of working clothes, consisting of cotton twilled fabric, Were chemically cleaned and then flameproofed. The flameproofing was carried out by treating the fabric for 5 minutes in 60 liters of trichloroethylene with an addition of 12 liters of ethyl glycol, in which 15% of anhydrous zinc chloride was dissolved. After centrifuging until the residual moisture was 80%, the suits were dried with hot air. The estimation of the flameproofing elfect was carried out, after air conditioning under standard conditions according to the DIN specification 53,907. In comparison with untreated goods, the following values were obtained:
- EXAMPLE 3 2 kg. of staple fibre gabardine were treated for minutes in 20 liters of monofluorotrichloromethane with the addition of 3 liters of isopropanol, in which 15% of anhydrous zinc chloride (DAB 6) and of coconut fatty acid polydiethanolamide were dissolved. The material was then centrifuged and dried as usual. The treated material in contrast to the untreated goods, was only difiicultly inflammable and had a soft handle.
- DAB 6 anhydrous zinc chloride
- EXAMPLE 4 25 kg. of welders protective suits, consisting of cotton material, were chemically cleaned as usual in a 35 kg. naphtha plant. The centrifuged textiles were treated in 200 liters of naphtha (boiling point 140200 C.) for 5 minutes with the addition of 24 liters of isopropanol, in which of anhydrous zinc chloride and 5% of a chlorinated paraifin with a chlorine content of about 70% were dissolved. After centrifuging and drying, the treated suits were satisfactorily flarneproof.
- a process for simultaneously flameproofing and cleaning textiles consisting wholly or substantially of cellulose or regenerated cellulose fibers which consists essentially of immersing said textile in a bath at a temperature of from to 35 C. for from 2 to 10 minutes, said bath consisting of (1) a solution consisting of from 5% to 35% by weight of anhydrous zinc chloride in an anhydrous solvent selected from the group consisting of (a) lower alcohols selected from the group consisting of ethanol, propanol, isopropanol and butanol, (b) glycols selected from the group consisting of ethylene glycol, 1,2-propylene glycol and 1,3-propylene glycol, and (c) carboxylic acid esters thereof with a carboxylic acid selected from the group consisting of acetic acid and propionic acid, and (2) an organic solvent utilizable for chemical cleaning selected from the group consisting of petroleum hydrocarbons of boiling points of 80 C.
- an anhydrous solvent selected from the group consisting of (a) lower alcohols selected from
- said bath having a concentration of 10 to g. per liter of said anhydrous zinc chloride, removing said simultaneously fireproofed and cleaned textiles from said bath and drying said textiles.
