Abstract
A method for dyeing nylon filaments for use in wear-indicating toothbrushes includes immersing a batch of a first nylon filament for between 10 minutes and 80 minutes in an aqueous solution containing between 0.01% and 0.19% weight to volume of Indigotine dye, said solution having a pH between 1 and 7 and having a temperature between 50 DEG C. and 90 DEG C., the dye penetrating into the filament to color an outer cross-sectional region and not penetrating into an inner cross-sectional region of the filament; removing the batch of the first nylon filament from the solution, and repeating the steps for a batch of a second nylon filament, reusing the same solution.
Description
The present invention relates to the fiber that toothbrush is used, people's United States Patent (USP)s such as Breuer 4,802,255.Described a kind of nylon monofilament, this monofilament has two coloured districts at least, one of them coloured district dyeing.In toothbrush bristles, just contain this monofilament, and when the user used this toothbrush, the color intensity in dyeing district changed with wearing and tearing.Indication when should changing, toothbrush is provided.People such as Breuer have listed 6 kinds of food colours and the colouring agent that can be used to dye monofilament, comprise indigo (according to " food medicine and cosmetics bill " No. second indigo plant, 5,5 '-the indigo disulfonic acid disodium salt), in the 4th hurdle, also narrated dyeing condition widely.Breuer etc. also provide the specific example of some colouring methods, comprise with indigo three embodiment (embodiment 4-6) when making dyestuff.
The disclosed specific colouring method of people such as Breuer is applicable to laboratory sample.But, for producing a large amount of coloured fibres of using at commercial toothbrush, need a kind of can on dye a large amount of fibers method.This method must be that cost is rational.Certainly, also should be able to produce the uniform nylon fiber of permeability.
In general, the present invention be to toothbrush with the colouring method in batch of nylon fiber, said here a collection of be at least two pounds of nylon yarns.This method comprises first nylon yarn was immersed in the aqueous solution 10 minutes to 80 minutes that this aqueous solution contains the bipseudoindoxyl dye of 0.01% to 0.1% weight/volume, and the pH value of solution should be between 1 to 7, and temperature should be between 50 ℃ to 90 ℃.When the impregnated with nylon silk, dyestuff penetration enters the outer zone of fibre section, but the internal layer area that does not enter the cross section.First batch of nylon yarn is taken out from dye liquor, just can be used as the toothbrush bristles of indication wearing and tearing.Second batch of nylon yarn can re-use same dye liquor, repeats same operation and dyes.Preferably then dye other silk in batches with same dye liquor.
In a preferred method, dye liquor contains 0.01% to 0.05% weight/volume bipseudoindoxyl dye, the pH value of this solution is between 2.5 to 4.5, solution temperature is between 70 ℃ to 85 ℃, be better than most and under atmospheric pressure carry out dyeing process in 60 minutes, and the nylon yarn diameter is between 0.127 to 0.356 millimeter (0.005 to 0.014 inch).
This method can be used for commercial mass-produced nylon yarn, and the mode that surpasses cost with benefit is produced the toothbrush of indication wearing and tearing.For example, this operation can be used for producing the nylon yarn of every batch 4.8 kilograms to 19.2 kilograms (10 pounds to 40 pounds), or even 48 kilograms (100 pounds) or higher batch.Importantly, same dye liquor can re-use once at least, even when using the 5th or the 6th time, bipseudoindoxyl dye still is penetrated into uniform, a uniform sectional area zone in the monofilament of producing.This method is implemented easily, safety, and a kind of stable dye liquor is provided.
In the description and claim of embodiment preferred, other advantage of the present invention is conspicuous.
People such as Breuer describe the nylon monofilament of the indication wearing and tearing of dyeing in detail, contain the toothbrush of this monofilament and make the method for this toothbrush.
In the method for the present invention, the dye solution of use contains the indigo of 0.01% to 0.1% weight/volume.If use too much indigoly, then too much dyestuff infiltrated fiber is dark excessively; If the dyestuff that uses is very few, then the dyestuff of infiltrated fiber is very few, and since first batch of fiber absorbs not enough dyestuff, dye liquor can not re-use.
Dye liquor temperature should be between 50 ℃ to 90 ℃, the too high rapid evaporation that then causes water of dye liquor temperature, and the concentration of dyestuff increases, and dyestuff is absorbed too fastly, thereby makes permeability restive.Dye liquor temperature is low excessively, and then dyestuff absorbed slow.
Dyeing process is preferably under the atmospheric pressure and carries out, thereby avoids using in factory huge press device.
Indigo is the acid stable dyestuff, and dye liquor must be acid.
The volume of dye liquor must be enough greatly, first fiber is with regard to the dyestuff of high percent too in the unlikely absorbent solution like this, and causes solution can not be used for dying second batch of fiber again.
Nylon yarn is monofilament preferably, and it should have suitable diameter to make toothbrush usefulness, preferably 0.2032 or 0.2286 millimeter (0.008 or 0.009 inch).
Nylon yarn should flood enough long-time in solution, to reach the outer diameter of section of fiber enough dyestuff penetrations is arranged, thus the performance that provides good indication to wear and tear.Preferably limit immerged time as far as possible, and should be within an hour.
Below describe most preferred method in detail.Employed equipment and dye liquor at first are described, operation then is described.
Dyeing process is to carry out in 2396 liters of (633 gallons) Whiting stainless steel dye vats.The size dimension of dye vat is 330.2 centimetres of 76.2 cm x, 101.6 cm x (30 inches * 40 inches * 130 inches).
Dye liquor in the dye vat contains 2396 liters of (633 gallons) distilled water; 7.7 rise glacial acetic acid and 555 grams, 100% indigo blue.Dye liquor temperature remains on 75 ℃ ± 1.5 ℃.
Also use the rinsing cylinder of two 2396 liters (633 gallons), be full of running water in the first rinsing cylinder, be mixed with No. 24 organic silicon emulsions of 1.5 liters of Dow Corning in the running water of the second rinsing cylinder.
Long 243.84 centimetres (8 feet) of employed monofilament, 0.2032 millimeter of diameter (0.008 inch), Wytex 6,12S nylon tow, its weight is about 4.8 kilograms (10 pounds).According to conventional operation, tow should carry out silicon processing, annealing, damping and combing before dyeing.Tow should not carry out drying before using.
Dyeing process
1) 4 synnemas is immersed in the dye liquor fully
2) autotimer being set is 45 minutes.
3) took out tow in per 1.5 minutes, immerse again in the dye liquor then, allow dye liquor between fiber, circulate.
4) after 45 minutes, tow is transferred to the first rinsing cylinder, carry out rinsing by flooding 4 to 5 times.
5) tow is transferred to the second rinsing cylinder, flood 4 to 5 times again proceeding rinsing, the arrangement that rinsing this time can regain in dyeing process to be lost.
6) combing tow again continues with normal drying and winding working procedure.
7) use same solution, other tow is in batches repeated above operation 4 times.After dying 5 batches of tow, change the dye liquor and first rinsing liquid, second rinsing liquid then is to change every day one.
Randomly, by heating dye liquor to 80 ℃ ± 1.5 ℃, the tow of some was flooded 30 minutes in this dye liquor, thereby adjust above operation.In addition, 4 batches of tow are different with once dying, and available this operation is dyed 10 batches of tow on once.
Other embodiment is in claims scope.
