In our previous lecture, we delved into the dyeing of cotton, a key cellulosic fiber. Today, we turn our attention to wool, a significant natural protein fiber. Understanding the chemical composition and properties of wool is essential for achieving effective and long-lasting coloration. We will explore why certain dye classes are particularly suited for wool…
Following our exploration of dye-fiber interactions, today we will focus on the practical application of these principles to a specific fiber type: cotton. As the most prevalent natural cellulosic fiber in the world, understanding how to effectively dye cotton is crucial for the textile industry. We will delve into the characteristics of cotton that make…
Welcome back to our series on Textile Dyeing and Dyes! In our previous lecture, we explored the classification of dyes based on their chemical structure and application methods. Building upon that foundation, today we will delve into the core of the dyeing process: the interactions between dye molecules and textile fibers. Understanding these interactions at…
Welcome back to our series on Textile Dyeing and Dyes! In our first lecture, we introduced the fundamental concepts and the historical journey of textile dyeing. Today, we will begin to unravel the complexities of the colorants themselves by exploring the two major systems used to classify dyes: classification by chemical structure and classification by…

For centuries, the ability to impart vibrant and lasting colors to textiles has been a crucial aspect of human culture, art, and industry. From ancient natural pigments to the sophisticated synthetic dyes of today, the…
1. Introduction to Polycaprolactone (PCL) Polycaprolactone (PCL) stands out as a biodegradable polyester with a diverse range of applications, marking it as a significant material in polymer science. This synthetic, semi-crystalline polymer is characterized by its biodegradability and a unique thermal profile, featuring a low melting point of approximately 60°C and a glass transition temperature…
Polyester has become an indispensable synthetic fiber in the modern world, dominating the textile industry and finding widespread applications beyond apparel. This lecture, the thirtieth in our series on textile fibers, will delve into the detailed chemistry of polyester, exploring its synthesis, structure, properties, diverse applications, and environmental considerations. Since its invention in the 1930s,…
Wool stands as a time-honored and commercially significant natural protein fiber, its utility woven into the fabric of human history for millennia. In the vast and varied world of textile fibers, wool occupies a prominent position alongside its natural counterparts, such as plant-derived cellulose fibers (cotton, linen) and other animal fibers (silk, cashmere), as well…
Introduction: Unveiling the Chemistry of Silk Silk, a natural protein fiber renowned for its luxurious feel and shimmering appearance, has held a significant place in human history for millennia. Primarily produced by the larvae of certain insects, most notably the mulberry silkworm (Bombyx mori), to form their protective cocoons, silk has been transformed into exquisite…
