Description

The invention relates to textile and light industry, in particular to a composition used for felling wool-containing textile materials, which can be used for a different assortment of wool-containing textile materials, primarily for coarse and technical cloths intended for the manufacture of products operated in the open air.

By felling is meant a technological process in which a cloth is created, characterized by bumpiness and the presence of surface covering. In the process of felling, the dimensions of the fabric along the length and width of the piece decrease and its thickness increases. At the same time, the heat-insulating properties, strength, density and softness of the fabric increase. Under the conditions of felling, a massive movement of the wool fibers relative to each other occurs, as a result of which they converge, become entangled and interlock, which leads to tissue shrinkage over the area and an increase in the weight of a unit of its volume [I. Technology for finishing woolen fabrics. M., "Light Industry", 1972, 364 S. (p. 77)].

Roll wool-containing textile materials is carried out in acidic, neutral or alkaline environments. The choice of method and the duration of the roll depends on the type of product, hardware design, quality and type of effect [Sadov F.I. Chemical technology of fibrous materials / F.I. Sadov, M.V. Korchagin, A.I. Matetskiy // “Light Industry”, 1968, 784 p.].

Felling in a neutral environment is very weak and is rarely carried out for thin woolen and semi-woolen fabrics with sensitive coloration.

The most widely used are alkaline compounds, including soap, soda and ammonia with synthetic products.

Known composition for rolls containing (g / l): biodegradable surfactants (Syntanol DS-10, Sintamide 5, Prevocell W, etc.) - 8-15 g / l and soda ash - 2-5 g / l) [Finishing and dyeing of woolen fabrics. Reference book / Under the general editorship of V.L. Molokova. - M .: Legprombytizdat, 1985, 264 p.]

The disadvantages of alkaline rolls are a significant decrease in the strength characteristics of wool and large losses in the form of a “failure” [Krichevsky G.E. Chemical technology of textile materials: Textbook. for universities in 3 volumes T. T. 1. M.:, 2000, 436 pp.].

Also, acidic compositions based on sulfuric, acetic, or formic acids are used for felling.

Known composition containing formic acid to a pH of 4-5. [Praise A. Textile excipients (reference guide): Per. with him. at 2 p.m. / A. Praise, V. Anger, K. Praise. - M .: Legprombytizdat, 1991. Part 1. - 432 p.] Or a composition containing 0.2-0.5% sulfuric acid [Peter R.Kh. Textile chemistry (Purification of textile materials from pollution). Per. from English G.E. Krichevsky, M .: "Light industry", 1973, 212 p.].

Known composition for felling hat felt, technical and clothing cloth, heavy scarves. It contains sulfuric acid to a pH of 4.5-6, an auxiliary component for felling 2-3 g / l and water up to 1 l [Praise A. Textile auxiliary substances (reference manual): Trans. with him. In 2 hours / A. Praise, V. Anger, K. Praise. - M .: Legprombytizdat, 1991. Part 1. - 432 p.].

The auxiliary component is an anionic or nonionic detergent, for example, Silastan AB, which is an alkyl aryl sulfonate, or Sinal Cal, a mixture of alkyl aryl sulfonate and fatty alcohol sulfate, or Lavotan HH, a condensation product of fatty acids.

The main disadvantage of all compositions is the lack of a component in it, which makes it possible to protect the woolen material from loss of strength during subsequent operation. So, it is known that wool is easily damaged by insolation: under the influence of sunlight (primarily UV radiation), keratin of the wool is destroyed, the fiber becomes weakened and yellow.

Closest to the invention is a composition for rolling wool-containing textile materials containing acid, for example sulfuric or formic, or acetic in an amount of 1-3 g / l, dehydrated silica gel, which is a waste product of the production of aluminum fluoride from the filtration stage of 3-20 g / l and water to 1 liter, which, due to the use of dehydrated silica gel as an auxiliary component, which is a waste product of the production of aluminum fluoride from the filtration stage, somewhat reduces the loss of strength of wool fiber by action insolation. [Patent 2465382 Russian Federation, IPC D06C 17/00. The composition for felling wool-containing textile materials / Vladimirtseva E.L., Zhelnova A.S., Sharnina L.V., Blinicheva I.B., Vilboy M.A .; Applicant and patent holder Federal State Budgetary Educational Institution of Higher Professional Education "Ivanovo State University of Chemical Technology". - No. 20111131398/12, declared 07/26/2011, publ. 10/27/2012, Bull. No. 30]. However, this decrease is small, therefore, felting with this composition does not allow to effectively protect woolen materials from sunlight.

The technical result of the invention is a significant reduction in the loss of strength of the wool fiber under the action of insolation and a noticeable increase in the effectiveness of protecting the wool material from sunlight. The whiteness (lightness) of the wool fiber does not change.

The specified result is achieved in that the composition for rolling wool-containing textile materials containing acid, an auxiliary component and water, according to the invention, as an auxiliary component contains TiO ₂ -column clays obtained by intercalation of titanium polyhydroxy complexes with the following component content, g / l:

Acid 1-3 TiO ₂ columnar clays obtained by intercalation titanium polyhydroxy complexes 3-10 Water up to 1 l

Moreover, as an acid, the composition contains sulfuric, or formic, or acetic acid.

Use as an auxiliary component of TiO ₂ -column clays obtained by intercalation of titanium polyhydroxocomplexes [Butman MF, Ovchinnikov NL, Karasev NS, Kochkina NE, Agafonov AV, Vinogradov AV Photocatalytic and adsorption properties of TiO2-pillared montmorillon titrated inter hydrated complexes. BeilsteinJ. Nanotechnol. 2018, V. 9. P. 364-378], together with well-known features, can reduce the loss of strength of the woolen material from the action of sunlight by 45-60%. The effect is achieved due to the specific structure of the wool fiber having an outer scaly layer and a system of micropores and microcracks up to 12 microns in size [Novoradovskaya TS, Sadova SF Chemistry and chemical technology of wool. M .: Legprombytizdat, 1986, 200 pp.], Which makes it possible to inlaid and firmly fix clay nanoparticles in them, enriched by hydrothermal intercalation with titanium oxide. In its native form, titanium oxide is not fixed on the wool fiber.

The composition contains the following components:

To create an acidic environment, various acids that are commonly used in textile finishing processes, i.e. non-volatile, explosive and fireproof, affordable, non-deficient, for example:

- Sulfuric acid (GOST 2184-77); formic acid (GOST 1706-78); acetic acid (GOST 19814-74);

- TiO ₂ -column clays obtained by intercalation of titanium polyhydroxo complexes (Butman MF, Ovchinnikov NL, Karasev NS, Kochkina NE, Agafonov AV, Vinogradov AV Photocatalytic and adsorption properties of TiO2-pillared montmorillonite obtained by hydrothermally titled obtained by hydrothermally. Nanotechnol. 2018, V. 9. P. 364-378)

- process water (GOST 17.1.1.04-80).

The composition is prepared in the traditional way. To do this, acid and TiO ₂ columnar clays obtained by intercalation of titanium polyhydroxy complexes [Butman MF, Ovchinnikov NL, Karasev NS, Kochkina NE, Agafonov AV, Vinogradov AV Photocatalytic and adsorption properties of Ti02-pillared compare by hydrothermally activated intercalation of titanium polyhydroxo complexes. BeilsteinJ. Nanotechnol. 2018, V. 9. P. 364-378].

Example 1

G / l are sequentially introduced into water (0.5 l): TiO ₂ -column clays obtained by intercalation of titanium polyhydroxocomplexes - 5, sulfuric acid - 1. The composition is mixed and adjusted to 1 l with water.

Example 2

G / l are sequentially introduced into water (0.5 l): TiO ₂ -column clays obtained by intercalation of titanium polyhydroxocomplexes - 3, acetic acid - 2. The composition is mixed and adjusted to 1 l with water.

Example 3

G / l are sequentially introduced into water (0.5 l): TiO ₂ -column clays obtained by intercalation of titanium polyhydroxocomplexes - 10, formic acid - 3. The composition is mixed and adjusted to 1 l with water.

Felling of textile materials is carried out according to traditional technology on standard equipment - warping machines such as SV-500Sh, SV-300Sh, SVF-500-Sh, etc. The fabric or fiber is impregnated with felling solution on special washing machines that provide more uniform application of the composition or directly on the warp machine, after which it is subjected to repeated influences of the organs of the machine, sitting down sequentially in length and width. The duration of the roll depends on the type of fabric [Shikanova I.A. Technology for finishing woolen fabrics. M, "Light Industry", 1972, 364 S.].

To obtain the correct comparative data, the claimed materials and prototype compounds processed the same materials using the same technology.

The effect of sunlight on the material was imitated on a PDS daylight device developed at the Central Scientific Research Institute of Scientific and Technical Information [Laboratory Workshop on Textile Materials Science / Ed. Koblyakova A.I. - M .: Legprombytizdat, 1986. - 343 p.] When irradiated for 48 hours. Damage to the woolen material was controlled by its solubility in 0.1 N alkali solution (NaOH) at a temperature of 65 ° C. The measure of wool damage was determined as the difference in the mass of the sample before and after processing, expressed as a percentage of the mass of the original dry sample. In this case, the mass loss during processing in alkali is greater, the more the sample is damaged during felling. A sample of the starting material was used as a reference sample. [Korchagin M.V. Laboratory workshop on the chemical technology of fibrous materials. Textbook for university students of the textile industry / M.V. Korchagin. - M.: "Light Industry", 1976, 352 p.].

The whiteness (lightness) of textile materials was judged by the magnitude of the reflection coefficient, determined on a Spectol-11 spectrophotometer at a wavelength of 540 nm.

Qualitative indicators of textile materials processed by the composition of the prototype and the claimed composition are shown in the table.

As can be seen from the data presented in the table, after felling with the claimed composition, the strength loss of wool fiber is from 5 to 10%, which is lower than after felling with the prototype composition. The whiteness (lightness) of the processed materials is maintained at the same level.
