Traditional textile colorations and functionalization consume a lot of energy, take a long time, and use a lot of chemicals; hence, cost-effective and eco-friendly natural dyeing and finishing have become a prime concern. In this study, natural dyes of black rice extract was extracted and used for the coloration and functionalization of wool fabric without using any hazardous dyes. The dyeing conditions were monitored using a one-variable-at-a-time technique, and it was discovered that the optimal dyeing conditions were M: L = 1:100, pH = 3, time = 60 min, and temperature = 90 °C. The dyed wool fabric with Al2(SO4)3 mordant shows higher fastness ratings of 4–5 for wash, 6 for light, 4–5 for dry rubbing & 4 for wet rubbing. SEM photographs confirmed the successful deposition of black rice extract on wool fabrics. In addition, mechanical properties, UV protection, and antimicrobial tests also revealed that the treated wool fabric has excellent UV protection capability and good antimicrobial properties along with adequate strengths. The ultraviolet protection factor was more than 35 in optimized conditions, and the strength increased more than 10% comparing untreated wool fabric. The antibacterial performances shown more than 80% reduction rate after 20 washing cycles. Therefore, the black rice extract are very promising and can be considered as the potential candidate for the sustainable dyeing and functionalization of wool fabric in the textile industry.

For producing a woven fabric, sizing is one of the important steps to increase the efficiency of weaving productions. Various sizing agents such as starch, carboxymethyl cellulose (CMC), wax, emulsifier, and polyvinyl alcohol (PVA) are frequently used in the textile industry. The aim of this study is to evaluate the sizing parameters of cotton using the modified sizing agent and the frequently used sizing agent in the industry. For modification of sizing agent, various sizing chemicals are mixed together by our own recipes. Then modified sizing agents are applied to the cotton fabric along with frequently used sizing recipes. After sizing, all treated yarn and fabrics are subjected to evaluate the performance of sizing parameters and the modified sizing agent shows tenacity (20.35–21.58 cN/Tex), elongation (18.50–10.78%), initial modulus (475–486 cN/Tex), yarn hairiness reduction (95.55–95.91%), yarn unevenness (0.10–0.35 CV%), abrasion resistance (13,990 times), weight loss during abrasion (0.05–0.07%), breaking force (900–1000 F/cN), extension during maximum load (3.4–4.15 mm), and thread breakage during weaving (2.7–3.1 CMPX). The result indicated that the modified sizing agent has an acceptable range of sizing parameters and even in some cases the performances are higher than the frequently used sizing agent. The recipe of modified sizing agent contains EKACELL DT-250, EKAVIOL BEZ and EKAWAX chemicals. The most important thing that the modified sizing agent reduces the chemical consumption as well as makes cost-effectiveness of weaving production. Which is definitely be economically sustainable development in the textile industry.
