Mercerization physical andchemical changes in cotton
Mercerization involves treating cotton fibers with a strong caustic soda solution. This causes physical changes in the cotton fibers by swelling the fibers and breaking old bonds. It opens up the fiber structure, swelling both the amorphous and crystalline regions. When removed from the caustic soda solution, new bonds are formed in the fibers. Mercerization increases the amorphous content and number of OH groups in the fibers. This results in higher moisture content, increased dye uptake, and increased reactivity of the cotton fibers. Mercerization can be done on yarn, hanks, warps, or fabrics and with or without applying tension during the process.
Scouring
The document discusses scouring, which is a process used to remove natural and added impurities from cotton fibers. It involves treating cotton with alkaline solutions such as sodium hydroxide. This removes fats, waxes, pectins and proteins from the cotton and improves its absorbency. The document then describes various scouring methods and chemicals used, factors to consider in choosing methods, and industrial scouring practices using equipment like kiers and J-boxes.
Lecture 3 mercerization
The document discusses the history and process of mercerization of cotton. It describes how John Mercer discovered in 1791 that treating cotton with a sodium hydroxide solution caused it to shrink. In the 1850s, Mercer patented the mercerization process. Later improvements by Horace Lowe and Thomas and Prevost reduced shrinkage by applying tension during treatment. The process was then commercialized in 1895 and is now widely used to increase cotton's strength, dye absorption, and other properties.
Mercerization of cotton
John Mercer discovered in 1791 that cotton fabric shrinks when exposed to a sodium hydroxide (NaOH) solution. In 1850, he patented the mercerization process, which involved treating cotton with NaOH. This resulted in increased strength, dye absorption, and hygroscopicity of the cotton fabric. However, shrinkage remained a major drawback until 1889 when Horace Lowe developed a method applying tension during NaOH treatment to reduce shrinkage and impart luster to the fabric. In 1895, Thomas and Prevost commercialized the process by applying tension during both NaOH treatment and washing, establishing mercerization processes still used today for cotton yarn and fabric.

The document concludes by describing common printing methods such as block, stencil, roller, screen, and digital printing.
General composition of print paste
The document summarizes the general composition and essential qualities of print pastes used in textile printing. Print pastes typically contain dyestuffs, thickeners, solvents, humectants, oxidizing agents, and defoaming agents. Thickeners are important for ensuring the print paste sinks into the fabric quickly and adheres properly after printing and drying. Other components like hydroscopic agents and pH controllers help facilitate dye fixation during steam treatment. Proper selection and balance of ingredients is necessary for achieving high quality, well-defined prints on fabrics.
Pigment printing
There are key differences between dye and pigment printing. Pigments have no affinity for fibers and are insoluble in water, requiring a binder to fix them onto fibers. Dyes have affinity for fibers and are water soluble. Pigment printing uses a binder that is an aqueous emulsion copolymer which polymerizes during curing to form a strong film embedding the pigment and adhering it to the fiber. Suitable thickeners for pigment printing are emulsion or synthetic thickeners which do not interact negatively with the binder. Emulsion thickeners are prepared using oil, water, emulsifiers and other agents, while synthetic thickeners are high molecular weight copolymers that thicken when
