Description

1 TARIFF DYEING OF WOOL TEXTILE PRODUCTS WITH DIRECT DYES A NEW STAINING METHOD USING METALLIC MORDANT SALTS Technical Area The invention relates to the treatment of woolen products such as fabrics and fibers in the textile industry with metallic mordants (chemical mordants). for staining with direct dyes in the presence of mordants and bio-mordants It relates to a newly developed staining method. State of the Art In dyeing wool fibers, which have a more complex structure compared to other fiber types... Physical factors, such as the physical structure of the fibers, are very important. Even in a sample of the same quality, Wool fibers have quite different diameters. Diffusion of the dye into the fiber occurs on the surface. 15 because of the fact that in fine fibers the unit surface area corresponding to the unit weight of the material is greater. Because of this, thinner fibers generally absorb more dye than thicker fibers. It adsorbs. In technology, acid and metal-complex dyes are primarily used in dyeing woolen fabrics. It is used. Temperatures can reach up to 105˚C during painting. Metal-20 Complex dyes are actually acid dye molecules and are used in dye production. It is produced by forming a complex with a metal such as chromium during the process. Metal-complex These dyes are acid dyes produced in complex form with metal. However, normal acid dyes... Unlike dyes, dye molecules are in a complex with a metal. It is found in 1:1 metal-complex paints, where one acid dye molecule mixes with one metal molecule at a rate of 25. two acid dye molecules in complexed and 1:2 (or 2:1) metal-complex dyes It is again complexed with a single metal. Chromium is the most commonly used metal. This The reason these dyes are called "acid dyes" is because of the dyeing processes. It must be done under acidic conditions. In the technique of dyeing woolen fabrics. There are studies that have been conducted using acid dyes. However, in these studies, acid 30 to improve the colors obtained after applying dyes to wool fabrics No action will be taken for this. Chromium mordant (or simply mordant) is used as an alternative dyeing method for woolen products. Although it is possible to use dyes, acid dyes can damage the fibers during the dyeing steps. 2 Chromium metal is added to the dyeing bath to create a complex in it. (Dyeing) The residual chromium metal remaining in the solution that is discharged as a result causes great harm to the environment. Because of the results it gave, chrome-mordant dyeing is not used today. Although woolen products can also be dyed with wool-type reactive dyes. Wool-type reactive dyes are not used because the desired color results could not be obtained in the applications. It is not preferred for dyeing products. Acid dyes used in dyeing woolen products are basically composed of three different molecules. as the molecular size of acid dyes used for dyeing increases Although an improvement in washing fastness was achieved first, the uniformity of dyeing was also affected. and achieving the desired color becomes very difficult. Small molecule acid dyes 10 With this method, even coloring and the desired color nuance are more easily achieved. Although dyeing is possible, the wash fastness of the dyes produced remains low. Wool In dyeing products with acid dyes, achieving the desired dyeing uniformity is crucial. It is not possible to achieve all the necessary fastness properties simultaneously. Therefore, the known techniques of this method... In this case, a new 15-inch dyeing process allows for both uniform dyeing and good wet fastness. A painting method is needed. Direct dyes, acid dyes, and dyes with anionic functional groups. These are substances. Chemically, their molecular structures are generally different from acid dye molecules. It is large. Direct dyes have historically been used primarily in cotton and viscose rayon, etc. They were used in dyeing cellulosic-based fibers. However, in the mid-1950s, these 20 the use of reactive dyes that have come to the market for dyeing fibers As a result of their increasing popularity, they have become less important in the market. The biggest reason for this is... Direct dyes cannot form strong bonds within the fiber structure and only hydrogen is used. Their ability to hold together within the fibers is due to weak forces such as bonds and van der Waals forces. As a result, the wet fastness of direct dye applications is lower. This 25 The advantage of dyes is that when their molecular size is further increased within the fiber, they age During processing, it becomes very difficult for them to exit the fibers, and as a result, their wet fastness is higher. Their ability to provide high coloring is remarkable. Direct dyes are particularly potent in solution. It is sensitive to acidic pH conditions. Wool fibers, in particular, have anionic functional groups. It can be stained with dyes at acidic pH values. 30 In industrial practice, the dyeing of fabrics made from wool fibers primarily involves... The wet fastness results obtained were poor, and direct dyes are sensitive to certain acidic conditions. Because they are, direct paints are not used. 3 In the literature review, WO9845527A1 is given as an example of the known state of the technique. Document number [number] can be shown. The document in question is wavy, irregular, shaded, and watery. It relates to a method for producing textiles that have a certain appearance.

However, chlorination is a prerequisite for dyeing wool fabrics. the application of the process, pre-simultaneous or post-mordanting application It is not mentioned in the document regarding the application of direct dyes to wool fabrics. No solution has been found to make it more efficient and increase its age-related durability. Our patent application numbered 2023 / 006582, found in the literature, concerns lyocell (lyocell) 10 A new two-step mordanting process for dyeing textiles with direct dyes. It relates to a dyeing method. The application in question concerns metallic dyeing of lyocell fabrics. mordants (chemical mordants) or bio-mordants before and after staining A method involving the use of wool is described. However, the mentioned application refers to wool. There is no information available regarding application to fabrics, and it is recommended for wool fabrics at 15. Chlorination followed by direct application of dye and pre- or simultaneous or by making the dyeing process more efficient through final mordanting applications It is not mentioned. In conclusion, due to the negative aspects described above and the current solutions regarding topic 20 Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made.

Tannic acid 15 is selected from among the pentahydrate (ZnSO4·5H2O) and chosen as a bio-mordant. (C76H52O46) is used. The method described in the invention prevents the excessive use of dye and achieves the target color precisely. obtained, post-dyeing use and color change caused by external factors are prevented, with direct dyes whose service life is extended and wet fastness is improved 20 Dyed wool textile products are produced. With this method, we achieve a longer lifespan. obtaining products with a long service life, reduced cost, and maximum benefit. is being done. In our invention method, dyeing is carried out within the pH range of 5-7. The dyeing process involves 25... The pH range used is obtained with weak acids. Within this specified pH range... The internal structure of the fiber becomes positively charged as a result of acid ion (H+) absorption. Under these conditions... below, negatively charged direct dye molecules in the dyeing solution interact with the fiber microstructure. It can form ionic (electrostatic) bonds. However, not every dye that enters the fiber can form bonds. the molecule forms weak hydrogen and van der 30 bonds with its surroundings within the fiber without forming strong ionic bonds. It is possible for it to form Waals bonds. In this way, it occurs within the fiber, especially near the fiber surface layer. The residual dye molecules are then washed away during subsequent use or in water. Upon contact, it dissolves and easily escapes from the fibers, polluting the surrounding environment. This The solution offered by the invention method to the problems is the direct dyeing of woolen products. This involves the use of bio-mordants and / or metallic (chemical) mordants in dyeing with these materials. 35 This dyeing solution is created using bio-mordants and / or metallic (chemical) mordants. This ensures that all the dye is absorbed from the solution by the fibers, and the acidic solution... ionic bonds, hydrogen bonds and van der Waals bonds that can form within the fiber in the environment In addition, all direct dye molecules within the fiber are coupled with mordant molecules. It forms water-insoluble complexes. This complex contains the negative substances of the dye molecule. It is formed as a result of the charge combining with the positive charge from the metallic mordant molecule. 5 As a result, the dye molecules lose their solubility in water. Firstly, all the dye molecules are drawn into the fiber from the dyeing solution, and wet fastness is achieved. The results are increasing. Direct dyes are classified as “Class A dyes”, “Class B dyes” and “Class C dyes” according to their molecular size. They are classified as "dyes". All these molecular size classes are the subject of the invention. It can be used in our method. The subject of our invention is the method used for woolen textiles. 0.5% of the mass (weight) of textile material (yarn, fabric, etc.) in dyeing of products. Direct dyes are used in amounts ranging from 8%. For example, a 3% dyeing solution; 100 kg of fabric (textile material) is immersed in a dyeing solution to which 3 kg of dye is added for 15 days. It indicates that it will be dyed (3% owf (based on fabric weight) has the same meaning). Large amounts of salt are used in dyeing woolen products with anionic dyes. It is necessary. The method described in the invention involves the processing of textile materials without the use of standard salt. 20 by using metallic mordant or bio-mordant in an amount ranging from 0.1% to 5% of its mass. Coloring is achieved directly with dyes. In addition to this coloring result... The dyeing process has high age fastness, minimizing color loss. For example, a 3% mordant addition means adding 3 kg of mordant salt to 100 kg of fabric (textile material). It states that it will be present in the staining solution. The acidic-basic properties of a solution are determined by the hydrogen (H+) and hydroxyl (OH–) ions present in the solution. They are given with concentrations. Both acidic and basic within the range expressed as the pH scale. The term 'pH' is universally used to describe the properties of a solution. pH values ​​between 1 and 7 indicate the properties of the solution. Acid properties are indicated by pH values ​​between 7 and 14, while basic properties are indicated by pH values ​​between 7 and 14. The invention relates to dyes with an anionic functional group (reactive, direct, acid, metal-complex). Although applicable to other fibers as well, these dyes are suitable for the relevant fibers (wool fibers and other The fixation reactions they form within the fibers are different from each other. Mordant application alters or additionally affects these fixation reactions. It creates new fixation mechanisms. The metallic 35 given in the invention 11 Other metallic (chemical) mordants or bio-mordants, distinct from (chemical) mordants It can also be used. Our invention was analyzed for wash fastness in the products obtained using this method. As standard, wool fabric is dyed directly with direct dyes, usually by chlorination. The sample fabric dyed using the method described in the invention is Iron(II) Sulfate. The dyes were stained with direct dyes in the presence of heptahydrate mordant salt. Staining After completion, no further washing is required; ISO 105 C06 B1M washing fastness. Wash fastness tests were applied according to the standard, and then the fabrics were dried.
