This monograph contains a collection of recent research papers focusing on advancing existing technologies and developing new technologies to improve the environmentally friendliness and save resources during the production of elastic leather materials. The papers : are organized based on the type of technological process used to preserve raw hides. A lot of attention is devoted to mathematical planning, simulations, and multicriteria optimization of the technological processes using newly developed chemical reagents. The Annotation monograph contains a complex study of physicochemical properties and characteristics of the resulting leather materials. The developed technologies were tested by the private joint-stock company Chinbar (Kyiv, Ukraine) and implemented at Ukrainian tanneries.

AUTHOR INFORMATION 387 | vi INTRODUCTION This monograph contains the results of the most recent studies on processing of raw leather and fur materials utilizing novel chemical reagents and examples of industrial implementation of the developed technologies. A wide variety of raw leather materials, namely cattle, porcine, rabbit, coypu, sheep, and equine hides, were used. The effect of new reagents, such as electrochemically activated water, modified montmorillonite, highly-dispersed SiO2 nanoparticles, bacteria and enzymes, and modified azo dyes on the properties of elastic leather and fur materials has been investigated. Most of the publications in this monograph are focused on studying a few related processes and their relationship with the subsequent processing of collagenous semi-finished leather products during multistage, mass- and energy-intensive technological cycle which usually involves applications of environmentally hazardous reagents. As a result of the presented studies, improved efficacy and environmental safety of leather and fur production was achieved. The process of regeneration of water balance during the soaking of a variety of raw hides with different density and thickness and processed by methods involving application of electrochemically activated water has been studied in detail [1–3]. Particularly, the soaking of equine raw hides can be efficiently carried out using fractions of electrochemically activated water - a mixture of catholyte with anolyte at a ratio of 5 : 1 [2]. The environmentally harmful sodium sulfide and sodium carbonate and surfactant are excluded from this soaking solution. Authors of the work [3] studied the effect of the developed soaking method of differently preserved raw hides on the properties of the resulting leather materials. The dependence of water sorption on the type of electrochemically activated water and treatment duration was determined. Effect of composition of alkaline solution and its temperature on the structural transformation in Page | 1 raw hides during removing preservatives, globular proteins, and mucopolysaccharides from its structure has been studied [4]. In the work [5] the layer-by-layer concentration of gelatin hydrolyzed from a pickled hide from different topographical areas (cuts) upon varying the enzyme concentration and the duration of liming process was determined.

  • Analysis of Artificial Leather with Textile Fabric on the Backside
    Volume 6, Issue 2, Fall2009 ANALYSIS OF ARTIFICIAL LEATHER WITH TEXTILE FABRIC ON THE BACKSIDE Darko Ujević, Stana Kovačević, *Larry C. Wadsworth, Ivana Schwarz, and Blaženka Brlobašić Šajatović University of Zagreb, Faculty of Textile Technology, Zagreb, Croatia *The University of Tennessee, Department of Materials Science and Engineering ABSTRACT The fundamental characteristics of a textile fabric intended for the vehicle interior is presented. Chemical and physical-mechanical properties of artificial leather with bonded textile fabric on the back side are analyzed. The most important parameters for leather durability are: breaking force and elongation-at-break, and these properties will be tested in different circular directions. Likewise, chemical properties of artificial leather and basic construction parameters of the textile fabric are investigated. When using artificial leather, physical-mechanical properties of artificial leather as well as the quality of the seams are most important. In addition to the results obtained, physical-mechanical properties and aesthetic evaluation of the joined places will be compared. Keywords: Artificial leather, Textile fabric on the back side, Joined place strength, Seam strength, Physical-mechanical properties Introduction pleather (plastic leather) is a slang term for synthetic leather made out of plastic, a In addition to ergonomically designed car portmanteau of plastic and leather, the term seats for keeping the body in a correct sitting can be either descriptive, or derogatory, position, it is important that the passenger depending upon the user (the derogatory use feels no bodily fatigue due to sitting implies use as a substitute for genuine discomfort.

  • Product Care Instructions
    PRODUCT CARE INSTRUCTIONS TEXTILES Care for textiles by vacuuming or lightly brushing. Rotate and flip cushions when vacuuming for even wear. Keeping textiles away from direct sunlight. The nap of high pile textiles (mohairs & velvets) may become crushed or lose its original pile height. We recommend light steaming to lift the pile to its original height. The textile should also be brushed with a de-linting brush to maintain its pile. Water based or solvent cleaner may cause discoloration or staining. We recommend that stained or soiled textiles be professionally cleaned. LEATHERS Leather is a soft porous material that is sometimes uncoated. It can easily absorb liquids and oily substances. Avoid saturating the leather with lotion or water. Care by dusting and lightly vacuuming. Keep leathers away from direct sunlight and heating vents. Leathers are a natural, “living” material that breathe and move as they wear. We recommend that stained or soiled leathers be professionally cleaned. VELLUM Vellum is a natural parchment produced from calfskin, lambskin, or kidskin. As it is a skin, there are naturally occurring variations in pattern, color, and texture, which may be noticeable in side by side panels. A clear coat of sealant is added to protect the vellum. Care for vellum by wiping gently with a damp to dry soft cloth, making sure that the skin is completely dried. Keeping vellum away from direct sunlight and heating vents. Vellum is a natural, “living” material and breathes and moves as it wears Vellum may also darken over time. We recommend that stained or soiled vellum be professionally cleaned.

  • Ethical Consumers' Awareness of Vegan Materials
    sustainability Article Ethical Consumers’ Awareness of Vegan Materials: Focused on Fake Fur and Fake Leather Yeong-Hyeon Choi 1 and Kyu-Hye Lee 2,* 1 Department of Clothing and Textiles, Hanyang University, Seoul 04763, Korea; [email protected]figure 2 Human-Tech Convergence Program, Department of Clothing and Textiles, Hanyang University, Seoul 04763, Korea * Correspondence: [email protected]; Tel.: +82-2-2220-1191 Abstract: With an increase in ethical awareness, people have begun to criticize the unethical issues associated with the use of animal materials. This study focused on the transition of global consumers’ awareness toward vegan materials and the relationship between the interest in ethical subjects such as animals, the environment, and vegan materials. For this purpose, consumers’ posts about fur/fake fur and leather/fake leather uploaded on Google and Twitter from 2008 to 2019 were utilized, and the Term Frequency-Inverse Document Frequency (Tf-idf ) value was extracted using Python 3.7. Furthermore, the worldwide Google keyword search volume of each word was analyzed using Smart PLS 3.0 to investigate global consumers’ awareness. First, with time, consumers began relating animal materials such as fur and leather to topics such as animal rights, animal abuse, and animal protection. Second, as interest in “animal welfare” increased, interest in “fake fur” also rose, and as interest in “cruelty free” increased, interest in “fake fur”, “vegan fur”, and “vegan leather” also increased. Third, as consumers’ interest in the “environment” increased, interest in vegan materials such as “fake fur” and “fake leather” decreased. However, as interest in “eco” increased, interest in “vegan leather” also augmented.
