F TO F: LEARN IT ALL
Introduction Textile dyeing is the process of introducing colour into fibres, yarns, or fabrics using dyes, auxiliaries, water or other media, and controlled conditions of time, temperature, and mechanical action. Conventional dyeing relies on water as the primary medium, whereas emerging technologies, such as supercritical CO₂, utilise compressed carbon dioxide as a solvent to carry … Read more
Introduction Fabric durability is one of the most critical parameters in textile performance evaluation, especially in upholstery, contract, and commercial applications. Among the most widely recognized abrasion resistance tests are the Wyzenbeek Test and the Martindale Test. Although both measure how well fabrics withstand repeated wear from rubbing, their methodologies, geographies of usage, and result … Read more
Prasanta DasAssistant ProfessorPanipat Institute of Engineering & Technology, Panipat, HaryanaEmail: pdas.aijuni@gmail.com Introduction In the world of textile manufacturing, blending is a crucial process that ensures the final product meets the desired characteristics, quality, and cost-efficiency. Raw materials, whether natural or synthetic, often exhibit variations in their properties due to differences in cultivation, production, or processing … Read more
Introduction Measuring the thermal insulation and water vapor permeability of fabrics is essential for evaluating their comfort, functionality, and suitability for various applications, ranging from winter clothing to sportswear and industrial textiles. Thermal insulation determines a fabric’s ability to resist heat transfer, a critical attribute for retaining warmth in cold environments. Methods such as the … Read more
In the world of textiles, ensuring the quality and performance of fibers, yarns, and fabrics is paramount. Various testing instruments are employed to measure different parameters, each providing crucial insights into the material’s properties. Here’s a comprehensive overview of some key textile testing instruments and the parameters they measure: 1. Crystallinity 2. Semi Crystallinity 3. … Read more
Introduction Azoic dyes, characterized by their insoluble azo group (-N=N-), are unique in that they are not available in a ready-made form. These dyes are produced through a chemical reaction between two components: a coupling compound (naphthol) and a diazo compound or diazo salt. The resulting colored substance is insoluble in water and exhibits excellent … Read more
