“…Besides, bleaching removes the chromophore group of natural coloring elements from the fibers and whitens the fabric according to the given dosages. Following three major functions, such as (a) soaking the cotton fabric with a bleaching agent and other chemicals, (b) increasing the temperature to the optimum level & for a certain period have to retain the temperature, (c) finally completely rinsing, washing and drying the cotton fabric; bleaching process has completed (6) . In some conditions, hydrogen peroxide bleaching sometimes may get combined with the cotton scouring process, where peroxide bleaching is accomplished under alkaline medium (7) .…”

Objectives: The objective of the study is to analysis the effect of chemicals on different physical properties and color fastness of treated cotton samples with standard rating values. Methodology: Five single baths are used for the pretreatment process with five different dosages such as 1g/L, 1.5 g/L, 2 g/L, 2.5 g/L, 3 g/L of NaOH and H 2 O 2. After that, reactive dyeing was performed for these five samples with a standard recipe. Findings: With the gradual increment of NaOH and H 2 O 2 dosages, the absorbency and whiteness index of pretreated samples were improved and for that particular reason bursting strength was degraded. On the other hand, for dyed samples, a little variation was observed in color fastness to wash and rubbing but the changes in the color shade of every sample were observable.

“…This introduces polar groups onto the fabric surface and makes the fabric hydrophilic [13]. Several authors [10,14,15] have reported that properties such as wettability, dyeability, adhesion, printability etc. can be improved by enzymatic hydrolysis.…”

Oxygen plasma treatment and/or cellulase enzyme treatment was carried to improve the surface properties of cotton fabrics for medical applications. The influence of Plasma (P), enzyme (E), plasma preceded by enzyme (EP) and enzyme preceded by plasma (PE) treatments on hydrophilicity of the cotton fabrics was studied using standard wicking test. The physical and chemical modification due to plasma and enzymatic treatments were analyzed using SEM and ATR-FTIR spectroscopy. The FTIR results revealed that the oxygen plasma has modified the surface chemically by introducing oxygen containing groups (C=O, C-O, COO -) onto the fabric surface and enzyme have hydrolyzed the cellulose molecule. The physical etching of the fabric surface was observed in SEM photographs and weight loss measurements. The modified fabrics were given antimicrobial finish and tested for its antimicrobial activity against S.aureus and E.coli using AATCC 100 test. The EP treated fabric was found to have 100% bacterial reduction. The wash durability of the finished fabrics was also assessed and the results are discussed.

However, most research focuses on introducing cationic sites into the cellulosic fibers for interaction with anionic dyes.…”

Glycidyl trimethyl ammonium chloride (Glytac) was used as a modifier for surface modification of jute fiber. Modifying effect factors such as Glytac concentration, sodium hydroxide concentration, temperature, and time were optimized as follows: Glytac concentration, 60 g/L; sodium hydroxide concentration, 20 g/L; temperature, 60 • C; and treatment time, 60 min. After the Glytac treatment, the zeta potential value on the fiber surface increased over a pH range of 3.5-9.5. Compared to the raw jute fibers, the modified jute fibers could be dyed with reactive dye using a small amount of salt and alkali and had higher K/S values under the same dye concentration range of 0.5-8. 0% (o.w.f.). Furthermore, the dyed Glytac-treated jute fibers had higher exhaustion, fixation, and total fixation and better washing fastness and dry rubbing fastness than those of raw jute fibers.
