Definitions
- This invention relates to the dyeing of nylon, and more particularly to an improvement in the process of dyeing nylon hosiery in which mono: filament and multifilament yarns of difierent denier are employed in their fabrication, such as in the manufacture of sheer nylon hosiery for ladies wear.
- nylon is used in this specification to designate the new synthetic, fiber-forming, linear polyamides generally referred to in the trade today as nylonand which are described in the patents of W. H. Carothers U. S. 2,071,250, 2,071,253, 2,130,523, 2,130,948, 2,174,527 and 2,195,166.
- the nylon to which the present invention relates more particularly is that synthetic, fiber-forming linear polyamide produced by the condensation of adipic acid and hexamethylene diamine, as described in the abovementioned patents.
- the hosiery dyed with the acetate dispersed colors had more color in the leg of the hose than in the welt, and this elfect detracted from the salability of the product because of the-psychological block apparently set up in the minds of those persons who had not accepted'hosiery dyed in contrasting strength in their various portions. It was, therefore, necessary to find some method for dyeing such hosiery with a good color union between the monofilament and the multifilament of varying deniers.
- a more specific object of this invention is to dye nylon hose, .constructed of from 10 to 20 denier nylon monofilaments in the leg and of 30to denier nylon multifilaments in the welt, with cellulose acetate colors by a method which will give goodcolor union between the welt and the leg.
- nylon hosiery constructed of monofilaments and multifilaments of varying denier can be dyed with dispersed cellulose acetate dyes in much more uniform shades where the dyeing is carried out in the presence of from 2% to 10% of tannicacid, based on the weight of the nylon being dyed.
- the dyeing, in the presence of the tannic, acid is preferably carried out in the presence of a weak organic acid, such as acetic acid or formic acid, although the use of the auxiliary acid may be omitted, where desired.
- Wetting and dispersing agents, such as the higher fatty alcohol sulfates may also be employed in treating the nylon material with the tannic acid solution.
- the hose are preferably scoured in the usual manner, rinsed free from the scouring assistants and then treated at temperatures of from to F. with a solution of tannic acid and acetic acid, with or without the addition in that solution of a higher fatty alcohol sulfate.
- the fiber so treated may then be dyed in the usual" manner with the cellulose acetate dyes at the temperatures ordinarily employed.
- the dispersed cellulose acetate dyes may be added directly to the tannic acid treating bath after the textile has been thoroughly wetted with the acid solution.
- the tannic acid-acetic acidcombination has been found-to give best results when used 'to pretreat the hose before dyeing. However, improved results can be obtained when the tannic acid acetic acid combination is added simultaneously with the acetate color at the start of the'dyeing operation.
- the preferred temperature for the dye operation is within the range of 155 to 165 F., for below 155 F. the dye absorption is too slow and above 165 F. the tendency toward the formation of creases in the nylon hose g is increased sothat highertemperaturesare preferably avoided.
- Example 1 -'-'A lb.'capacity drum rotary dyeing -1iiachine was charged with 19 gallons parts based on the weight of the -hose) of softened'waterand 4' lbs: (dryweight) of scoured and rinsed womens" nylon hosiery with a 15 denier 'xn'onofi'lament b'ootand'a40 denier multifllament twisted welt. There was added 0.193 lb. of tannic 'acidand 0.11 lb; 'of acetic acid (28% strength) with continuous'agtltationof the hose at 90 l. The temperaturewas raised to 125 130 F. and agitation continued for 15 minutes.
- Example 2 The same colors employed in Example 1, and which were dispersed in water with 0.25 lbl of 191229 9 w e addem 0.171 1b.--Yellow azo dye (40% color solids) 0.171 'lb.-Acetamine scar1et'B"(30%color solids) 0.235 'lb.'-Celanthrene brilliant blue FFS (36% "ch1or"so1ids) 1' The temperature was raised to F. and the dyeing'run for one hour at this temperature.
- T b t was dr ed. he o e We'll rinsed with'wa'ter. andfinally dried.
- a Mistique shade (1947 Fall Season Hosiery 'Color Card'of America) was obtained with an excellent color unionbetween the boot and the welt.
- the temperature was gradually raised over 15 minutes to 160 F. and held for three-quarters of an hour.
- the hose were dyed a dark brown shade with good union between the leg and the welt.
- tannic acid For light hosiery shades, it is recommended that a combination of 5% of tannic acid and 3% of acetic acid (28% strength) be used. For dark hosiery shades, of tannic acid and 5% of acetic acid (28% strength) has been found suitable. For very light shades, as little as 2% of tannic acid will be sufi'icient, and even less acetic acid. As stated above, when desired the acetic acid may be omitted, but in general it is found advantageous to use at least small amounts. The percentage figures represent the percentage based on the dry weight of the hose.
- the tannic acid in which the nylon hosiery is to be treated may be of any desired volume, preferably from 20 to 40 parts of water per part of nylon to be treated, which volumes are similar to those normally employed in the dyeing of the nylon with water insoluble dispersed cellulose acetate dyes.
- any detergent, wetting and dispersing agent preferably one that is insensitive to calcareous water which operates in acid solutions, may be employed.
- the present invention is not dependent upon any specific detergent or wetting agent.
- a process of dyeing nylon hosiery composed in part of monofilament and in part of multifilament yarns of different denier with water insoluble dispersed cellulose acetate dyes which comprises treating the nylon in an aqueous bath containing from 5% to 10% of tannic acid and from 3% to 5% of an acid of the group consisting of acetic and formic acids, both percentages being based on the weight of the nylon, and applying the water insoluble dispersed dyes by heating the nylon in the aqueous dispersion thereof.
- a process of dyeing nylon hosiery composed in part of monofilament and in part of multifilament yarns of different denier with water insoluble dispersed cellulose acetate dyes which comprises treating the nylon in an aqueous bath containing from 5% to 10% of tannic acid based on the weight of the nylon, and thereafter applying to the nylon containing the tannic acid the water insoluble dispersed dyes by heating the nylon in the aqueous dispersion of the dye.
