    In defense of tailoring and textile design
    (New Vision, 2018-04-18) Mayanja, Kibirige Muhammed
    The sudden announcement of a new curriculum by National Curriculum Development Centre (NCDC), on April 10, has tickled the minds of many Ugandans because the process of the changes is questionable since most stakeholders were not consulted. Also the the subjects retained and those dropped as well as those combined left a lot to be desired. One of the vital subjects which was dropped is tailoring and textile design on our curriculum.

    Optimization of process conditions of silk fabric dyeing with galinsoga parviflora leaf extract for antibacterial application.
    (The University of Oradea, 2021) Musinguzi Alex; Mwasiagi, J. Igadwa; Nibikora, Ildephonse; Nzila, Charles
    Silk being one of the organic natural fibers, is susceptible to microorganisms’ attack thus leading to loss of physical aesthetic and mechanical properties. The present study was focused on optimizing the dyeing process parameters (Extract concentration and dyeing temperature) of dyestuff extracts from the Galinsoga Parviflora plant and analyzing the antibacterial activity of the dyed silk fabric. The Pad-dry method was used for the application of herbal dye extract onto selected silk fabric and the AATCC 100:2019 test method was used in assessing the treated fabric quantitatively against Staphylococcus Aureus and Pseudomonas Aeruginosa bacterial strains. Dyeing conditions obtained using Central Composite Design (CCD) indicated that dye concentration and temperature of 39.14 percent and 700C respectively could be deemed as optimum. Also, the Analysis of Variance (ANOVA) results showed that extract concentration has a statistically significant effect on bacterial count whereas the effect of temperature was not so much influential. Silk fabric dyed with optimized values demonstrated a 99.33% and 99.15% reduction in the bacterial count against Staphylococcus Aureus and Pseudomonas Aeruginosa bacterial strains respectively. Also, its fastness properties to light, washing, and Rubbing ranged from very good to excellent (4-5 to 5). Thus, in general, this research confirmed that Galinsoga Parviflora plant leaves, abundantly available in most parts of Uganda can be used as an antibacterial finish on silk fabric for improved bacterial resistance.

    Synthesis of chitosan modified rotten bagasse biochar for lead (ii) ions removal from industrial paint wastewater
    (Busitema university, 2026) Mutyaba, Fahadi; Latabo, Jacquline
    Lead (II) ions presence in industrial wastewater poses a critical environmental and public health challenge where paint manufacturing industries discharge effluents containing lead concentration as high as 3.88mg/L far exceeding the NEMA permissible limit of 01mg/L and the WHO drinking water guideline of 0.01mg/L. conversional remediation techniques such as chemical precipitation, ion exchange, reverse osmosis and electrochemical reduction are effective but very costly, energy intensive and produce possible secondary pollutants creating an urgent need for low-cost, locally viable and environmentally sustainable alternatives. This study therefore synthesised and evaluated a chitosan modified rotten bagasse biochar as an adsorbent for the selective and efficient removal of lead (II) ions from real industrial paint wastewater. Sugar cane was subjected to anaerobic biodegradation for 2 months to enhance porosity and mineral content, then pyrolysed under limited oxygen at 600℃ for 2 hours to produce RBB which was subsequently modified with chitosan. The bio composite adsorbent was characterised using SEM-EDX and FTIR which revealed the presence of mineral elements due to decomposition and increased surface function groups (-NH2 and -OH) after chitosan modification suggesting ion exchange and surface complexation during adsorption. Optimal adsorption conditions were established at an adsorbent dosage of 1.65g, pH of 6.7 and contact time of 80 minutes with predicted maximum removal efficiency of 87.4% and an equilibrium adsorption capacity of 1.835mg/g which was superior to both pristine RBB (1.23mg/g) and Ch-RBB (1.49 mg/g). Adsorption kinetics were best described by the PSO model with R2 = 0.988 which confirmed chemisorption as the dominant rate controlling mechanism while Boyd model analysis indicated that film diffusion governs the initial adsorption stage and intraparticle diffusion controls the later stage, together constituting a multi stage diffusion controlled process.
