The composition of the paste for printing cellulose-containing materials kovovymi dyes

 

(57) Abstract:

The invention relates to the textile industry, namely the technology of coloring textile materials kovovymi dyes. The essence of the invention lies in the fact that the composition of the paste for printing cellulose-containing materials, including VAT dye, sulfoxylate reducing agent, an alkaline agent, an antioxidant and Segundo, as an antioxidant contains surfactant based triethanolamine salts of alkylphenol solitaire, surfactant-based product of esterification alkylpolyoxyethylene ether with acetaldehyde in the presence of butanol and biological product containing oxidoreductase, acting on hydroperoxide connection, and/or amylase ecstasty. The invention allows to obtain stable results of color in the wavelength range of the visible and infrared part of the spectrum with disabilities index of intensity of color for not more than 1,025 times and rate of remission is not more than 5% within a technologically acceptable values. However prevents substantial depolymerization of cellulose fibers can result in the loss megaheels of coloring textile materials kovovymi dyes.

The main components of pastes for printing fabrics kovovymi dyes along with dye are sulfoxylate reducing agent, an alkaline agent to transfer the pigment in salt lakecity able to diffuse into the cellulose fibers, and a thickener to specify certain thixotropic properties of the composition. In the paste composition may further include various additives target: for dispersion and dissolution of the dye, to retain moisture in the layer of printing ink during the drying process the tissue, for example glycerol, xilian, urea, aliphatic alcohols, etc., In particular, the well-known composition containing (g/kg):

- dye - VAT dye with the brand "P" 80 - 200,

- sulfoxylate restorer - rongalit (hydroxymethanesulfinic sodium) - 100-160,

- alkaline agent potash (sodium carbonate) - 100-150,

- dispersant and water-retaining additive is glycerol - 80,

starch or starch-tragety thickener and water up to 1000 [Finishing of cotton fabrics / Ed. by B. N. Melnikova. - References:., 2 h // h 1. : Technology and the range of cotton fabrics. - M.: Legprombytizdat, 1991.- S. 267].

Rongalit among sulfoxylate vosstanovitelya based sulfoxylates acid: rongalit and its analogues. M.: Chemistry, 1984. 160 C.]. However, at elevated temperatures in the processes of preparation of the printing paste and drying it after printability costs of reducing agents on the adverse effects are so great that in practice, the use 10-20-fold molar excess of rongalite towards kubulau dye.

It is known that along with oxidation during drying fabric substantial loss of rongalite occur between drying and selenium ink composition [Krichevsky, that is, the Chemical technology of textile materials/ Textbook. for universities in 3 so, so 2.- M: Rossiter, 2001.- S. 364-365]. In real production conditions, the equipment for drying the fabric after printing, the dye composition and fixing the dye by steaming in an environment saturated water vapor (selenia) do not aggregate. Laid in carts dried fabric is in the air for some time, and this time variable for fabrics of different trucks, and for the lower and upper ends of one truck, and can reach up to several hours.

The reactions involving rongalite and atmospheric oxygen, characterized by the exothermic character, and the temperature rise of the material in the trucks easily fixed by eagle after drying not more than 0,5-1,5 hours However, in these conditions, the degree of polymerization of the cellulose may be reduced by 6-10%. Longer prone tissues in the cart dramatically increases the depolymerization of the fiber, which leads to loss of mechanical strength of the fabric. The negative impact of the products of oxidative degradation of rongalite on the state of the dye is manifested not only in the lack of the fullness of his recovery and fixation on the fiber, which reduces the intensity of the color, but also in the destruction of the pigment with the formation of products that change the refractive index of the painted areas in the IR range (remission). This figure is very important in the manufacture of camouflage colors on fabrics for military purposes. To ensure masking effects and the inability to recognize objects using night vision devices should be in accordance with the natural background to create a breakdown of the fabric on the site-specific indicators of remission. In particular, for widespread tri-color camouflage remission brown parcels should be 10-20% for dark-green - 30-40% for olive 50-60% [Razuvaev, A. A. Practical coloring army camouflage/ Textile chemistry, 2000, 2(18). - 100 C. the spins of rongalite (Na2S2SO3, Na2S2O3, formaldehyde) [Makarov, S. C., Polenov Y. C., Budanov centuries Polarographic study of the decomposition of rongalite in aqueous solutions, Journal of neorganic. chemistry, 1984, T. 29, 10.- C. 2456-2460; SU 941356, C 07 C 145/00, From 08 To 5/41, publ. 07.07.82].

The known composition of the printing paste, in which the additives are present, the antioxidant is sodium sulfide in the amount of 2% by weight of reducing agent [Panina H. N. and other Express fixation of VAT dyes in printing fabrics made of cellulose fibres/ Textiles, 1985, 8.- C. 12]. The composition contains (g/kg):

The dye is a VAT dye paste) - 100

Sulfoxylates restorer - rongalit 1:1 with zagustai - 180-200

The alkaline agent potash 1:1 with water - 200

Antioxidant - Na2S - 3,6-4,0

Sagasti Up to 1000

With the release of tissue from the range f-ing them. O. A. Varentsova (, Ivanovo), due to the additives of sodium sulfide, the duration of selenia has been reduced from 10 to 2 min, which resulted in lower consumption of heat (82%) and electric (34%) of energy to increase by 18-20% indicators of the intensity of the color by reducing 30% of consumption rongalite in comparison to the earlier modes kolori the drop drying fabrics with high surface density of from 5 to 30 min, a deterioration of the index of intensity of color in the visible wavelength range 10-20%. When increasing the interval between operations of drying and selenia more than 1 h, which is often the case in production, dramatically changing the coefficients of reflection in the infrared range and degree of polymerization of the cellulose, and the duration of this interval of more than 2 h was observed the decrease of the breaking load.

Closest to the invention is a paste composition for printing cellulose-containing materials kovovymi dyes using antioxidant sodium sulfite in the number of 22-30% by weight of rongalite and urea as a dispersant and water-retaining substance [SU 1686049 A1, D 06 P 1/22, publ. 23.10.91]. The composition contains (g/kg):

The dye - VAT dye - 10-100

Sulfoxylates restorer - rongalit WITH - 60-90

and

Hydrosulfite sodium - 3-10

The alkaline agent - potash - 40-60

and

Caustic soda (20%) - 20-50

Dispersant and water-retaining additive is urea - 50-100

The antioxidant is sodium sulfite - 20-40

Sagasti Up to 1000

This structure allows to increase the color intensity and decrease its change with increasing duration of high-temperature drying up to 30 minutes of the Receipt of such technical effect is due to the total resultslimit sodium.

However, this composition does not provide a stable performance color and strength of a textile material with increasing duration of the interval between operations of drying and selenia 1.5 h and more. The index of intensity of color varies from 1.1 to 1.25 times the reflectance of the infrared rays (remission) deteriorates by 12-18% is the depolymerization of cellulose and loss of mechanical strength of the textile material under the influence of atmospheric oxygen.

Thus, the known technical solutions do not allow to obtain stable indicators of coloring textile materials kovovymi dyes in the wavelength range of the visible and infrared part of the spectrum, to prevent significant depolymerization of fibrous material and loss of mechanical strength with increasing interval between the operations of drying and selenia more than 1.5 hours

Inventive task consisted in finding the composition of the paste for printing cellulose-containing materials kovovymi dyes, including coloring matter, sulfoxylate reducing agent, an alkaline agent, an antioxidant and a thickener, which would allow to obtain stable performance color in the wavelength range of visible and infrared Spa is the problem is solved, however, the composition of the paste for printing cellulose-containing materials, including VAT dye, sulfoxylate reducing agent, an alkaline agent, an antioxidant and Segundo, as an antioxidant contains surfactant based triethanolamine salts of alkylphenol solitaire, surfactant-based product of esterification alkylpolyoxyethylene ether with acetaldehyde in the presence of butanol and biological product containing oxidoreductase, acting on hydroperoxide connection, and/or amylase ecstasty, the next component content (g/kg):

VAT dye - 10-150

Sulfoxylates restorer - 50-175

The alkaline agent is 40-70

Surfactant-based triethanolamine salts of alkylphenol solitaire - 0,56-1,81

Surfactant-based product of esterification alkylpolyoxyethylene ether with acetaldehyde in the presence of butanol - 0,056-0,181

Biological product containing oxidoreductase, acting on hydroperoxide connection, and/or amylase ecstasty - 0,048-0,185

Sagasti Up to 1000

Thus, the main feature of the invention is the simultaneous use as alkylphenolethoxylates of solitaire;

- surfactant-based product of esterification alkylpolyoxyethylene ether with acetaldehyde in the presence of butanol;

- biological product containing oxidoreductase, acting on hydroperoxide connection, and/or amylase ecstasty.

The invention allows to obtain stable results of color in the wavelength range of the visible and infrared part of the spectrum with disabilities index of intensity of color for not more than 1,025 times and rate of remission is not more than 5% within a technologically acceptable values. However, to prevent substantial depolymerization of cellulose fibers, can lead to loss of mechanical strength of the fabric.

Technical effects of the invention are not achieved by the exclusion or replacement of any components. Not any substance having surface-active properties, antioxidant sulfoxylate reductants. In particular, low molecular weight alcohols used in the composition for dyeing and printing cellulosic fiber materials [SN 680180, D 06 P 1/22, publ. 15.07.92], increase the surface tension of solutions. However, due to increased solubility of Colorline of hydrosulfite in mixtures of water and alkanols.// Meiwes. Proc. of the Progress of engineering and technology finishing production." - Ivanovo, 1992.- C. 113-117].

Known inhibition of oxidation of rongalite the acetal of alkylphenolethoxylates (phenoxy BV 9-10) or naphthalenesulfonate sodium (dispersant NF), which are surface-active substances, while other surfactants (wetting of sulfated-31 or monoalkylphenols ether of polyethylene glycol is the primary fatty acid - neonol P 1214-3) have a negative impact on the results of the synthesis of rongalite [Ivanov Century. Century. and other Influence of interphase mass transfer on the reaction kinetics and the results of multi-stage synthesis of hydroxymethanesulfinic sodium (rongalite)/ Journal of applied chemistry, 1995, I. 68, 5.- C. 741-745].

However, it is known that the use of dispersant in NF Crusades composition slows down the kinetics of recovery of dyes, so the degree of fixation of the dye is reduced by 17...20%, a measure of the lightness of the color is increased by 15. . .18%, which indicates the decrease of its intensity [Ivanov centuries the Influence of magnetic fields on alkali-hydrosulfite solutions// J. struct. reports of the Scientific-practical conference. teachers and staff IHTI.- Ivanovo, 1990. -C. 56].

PRA can be used VAT dyes in the form of fine powders or in a special liquid discharge form with the label "P" (pasta), the latter is more preferable. When using the powder form of the dye (labeled "D") in the composition will further include substances for dispersion, recovery and partial dissolution of the pigment.

As sulfoxylate reducing agent can be used, for example, rongalit or in combination with hydrosulfite. Rongalit, it is difficult soluble in water, introduced into the paste or in the form obtained by heating the solution or in the form of a mixture of reducing agent with zagustai in the ratio 1: (1-1,5).

As the alkaline agent can be used traditionally applied potash, mostly in the form of a 50% aqueous solution, or in combination with caustic soda.

As surface-active substances on the basis of triethanolamine salts of alkylphenol solitaire can be used industrially produced excipients, for example the preparation of sulfated 61 or adduct drug interactions OP-7, which is monoalkyl ether of polyethylene glycol with chlorosulfonic acid, and subsequent neutralization with triethanolamine. The General formula of the compounds which are the basis of surfactants:

- Cnacid 61 (TU 2484-143-05744685-95-1) production of JSC "ivhimprom" (, Ivanovo) as a main component (61%) contains a compound of the above formula where n=9, m=10. Used traditionally as malpraxis biologically soft wetting and washing agent for processes rasshifrovka, otwarte, bleaching, dyeing, washing fabrics in the composition of the medication;

- adduct drug interactions OP-7 with chlorosulfonic acid and subsequent neutralization with triethanolamine get well-known reaction of sulfoacetate various alcohols chlorosulfonic acid [for example: Abramson, A. A., Zaichenko L. P., finegold S. I. Surfactants. - L.: Chemistry, 1989.-C. 19]. The adduct contains a mixture of compounds of the above formula where n= 8-10, m=6-7. The ratio of the volatile components of the mixture depending on the composition used in the synthesis of the drug OP-7 [Surfactant/ Ed. by A. A. Abramson, and M. Gayova. - L.: Chemistry, 1979.- S. 305.].

As surface-active substances on the basis of the product of esterification alkylpolyoxyethylene ether with acetaldehyde in the presence of butanol can be used industrially produced excipients, such as sentenal BV (THE 6-36-744684-85-90), or the adduct of vzaimodeistviyami, which is the basis of surfactants:

CnH2n+1-O(CH2CH2O)m-CH(CH3)-OS4H9;

- sintana BV contains 91% of the compound of the above formula where n=9, m=10;

- adduct interaction cintanya ALM-10 with acetaldehyde in the presence of butyl alcohol is prepared by known esterification reaction of aliphatic alcohols aldehydes [for example: Stepanenko B. N. The course of organic chemistry (in two parts), 1 o'clock. Textbook for high schools, ed. 5-e, revised and enlarged additional M.: Higher school, 1976. - S. 174-175]. The reaction takes place in the presence of dehydrating compounds which can be used sulfuric acid. The adduct is a mixture of fixed composition containing the product of esterification of the above formula (n=12-14, m=10) and unreacted sintana ALM-10: CnH2n+1-O(CH2CH2O)mH.

As a biological product may be used, for example, products of the cultivation of microorganisms of the Russian national collection of industrial microorganisms (VKPM) Gosniigenetika:

Trigonopsis variables Y-1689 containing catalase (K. F. 1.11.1.6),

Phellinus igniarus F-686 or Phanarochaete chrysosporium F-615 containing peroxidase (K. F. 1.11.1.7),

Rh,4--D-glucosidase (K. F. 3.2.1.3),

Aspergillus niger F-745 or F-679, simultaneously producing enzymes of the oxidoreductase, acting on hydroperoxide connection, and amylases ecstasty (K. F. 1.11.1.6, K. F. 3.2.1.2, K. F. 3.2.1.3); and drug Superoxide dismutase [9054-89-1] company "ICN Biomedicals" [catalog Pharmaceuticals INC, 2000. - P. 638-639] or domestic drug Glucosamin G3x (TU 483-05803077-02-93).

Pasta is prepared, for example, as follows.

Pre-prepare a 50% solution of potash, a mixture of rongalite with zagustai by the cooking of the starch, the introduction of solid rongalite and its dissolution in the process of cooling with stirring. When using special additives to prepare their solutions, and if necessary, the solutions rongalite, for example, when heated with live steam. Then RUB clean the VAT dye with a dispersing and dissolving the target additives, is mixed with aqueous 50% solution of potash, with a mixture of rongalite with zagustai and target solution additives, if they are needed. Then the resulting mixture is mixed with the calculated quantity of sagasti and antioxidant. At the same time allowed the introduction of the mixture of surface-active substances, together with the enzymatic or biological product apart from it.

SUBSTANCE: invention relates to the textile industry in particular, to the technology of the final softening of the linen dressing. It describes the enlymatic method of final softening of the linen dressing that includes enzymatic procession of the linen by covering the straightened linen with the solution of multienzyme preparation with the indicator the enzyme activity, in un/ml: endopolygalacturonase - 15-40; α-L- arabinofuranosidase - 12-20; endoxylanase - 20-35; exoxylosidase - 0.7-1.5; pectinesterase - 1.5-7.5; exopolygalacturonase - 0.4-2.5; endogalactanase - 15-25; exogalactosidase - 0.8-1.7; exoglucanase - 1.0-1.9, with the addition of 15-30 g/l of sodium bicarbonate and complexon on the basis of aminopolycarboxylic acids at 40-50°C temperature, further holding of the linen during 30-40 min.; steam procession at 98-105°C during 5-7 min.; and procession at the needle carding machine to form the structure of the ready linen. Covering the linen with the solution of multienzyme preparation is made either by the method of fluid soaking with the additional weight after wringing for 95-100% or applying gas and fluid foam with the additional wet weight for 25-40%.

EFFECT: invention helps to add the softening napping effect to the linens, to increase the durability of the material and elasticity of the fabric; to decrease accumulation of irreversible deformation after its repeated stretching; to improve the ability to drape; to decrease general colour difference ΔE to the level of visually undefined deflections not exceeding 1,0 un.
