“…Most disperse dyes are based on azo compounds; nevertheless, anthraquinone derivatives are frequently used to produce violet and blue colours [73]. These colours are usually insoluble in water or only slightly soluble, non-ionic, and placed on hydrophobic fibers from an aqueous dispersion [15].…”

Dyes are substances that enhance the appearance of finished goods by providing uniform colour. Dyeing is the application process of dyes that are fixed in textile fibers. The dyeing process uses various steps, including pre-treatment, desizing, scouring, bleaching, carbonizing, degumming, and mercerization. Water is considered the primary medium for applying dyes and other chemicals for this treatment in the dyeing process. The dyeing process contains many toxic chemicals, metals and non-soluble substances, such as wastewater, which is thrown into the environment. It is noted that, during dyeing , around 50-300 liters of water is required for 1 kg of fiber. On the other hand, 1-2 million liters of water are needed every day for 50,000 meters of daily production. This massive amount of toxic wastewater is highly harmful to the environment, human health, aquatic system, soil, air, water, plants, and animals. This review paper states various dyeing processes with different dyes, including acid dye, direct dye, sulfur dye, reactive dye, vat dye, metal complex dye, azo dye, disperse dye, and basic dye. In contrast, it also describes the influencing factors of dyeing processes and methods. Moreover, this review demonstrates the impacts of textile dyes on the environment (water, soil, air emissions, human health) and illustrates possible remedial actions regarding wastewater.

“…Modern tendencies of recent developments of tapes manufacture are connected with a use of the new modifications of components, i.e. blends of polyolefins and olefinic monomers 1,6,7 as well as with the supplementary applications of various types of additives [8][9][10][11][12][13][14][15][16][17][18][19] for improving whiteness, antistatic properties, soiling resistance and great number of other qualities. Multifunctional additives can improve homogeneity and mixing of all the components, but their positive/negative effects on basic properties of tapes are almost unknown.…”

“…Nano additives of high functionality are also used [20][21][22][23][24][25] . For enhancement of functional properties of polyolefin materials, the inorganic fillers as calcium carbonate, talc, silica and others are important materials 8,16,26,27 . For instance, calcium carbonate provides opacity and surface gloss of polymeric products, but, for complex compositions of tapes, these effects were not studied.…”

The present paper studies the effects of the additions between 3.00 and 7.00 wt% of additive Granic 422 instead of polypropylene on polymeric tapes properties as color difference, structure and tensile parameters. Micro-structural analysis revealed additional agglomerations of calcium carbonate particles on the surfaces of the tapes after application of new portions of the variable additive. Compositionproperty relations showing the changes in properties of tapes were suggested. For increase in color difference of the tapes from zero to 0.18, a logarithmic relation was used. For other indices, the linear relations were proposed. On the basis of the relations, the positive changes of 2.0-2.7% in macrostructural parameters (width, thickness, linear density) and negative changes of 2.1-8.8% in tensile characteristics were obtained.
