This chapter highlights on the applications of marigold plant extracts as an antibacterial and antimicrobial best dyer for textiles. Tagetes erecta usually known as Marigold is a vital wellspring of carotenoids and lutein, developed as a nursery plant. Marigold blossoms are yellow to orange red in colour. Now a days, lutein is transforming into an unquestionably common powerful fixing, used as a part of the medicines, food industry and textile coatings. This has increased more noticeable vitality of marigold and its exceptional concealing properties. Regardless of the way that marigold blooms; its extract has been used as a measure of veterinary supports. The examination was directed to contemplate the usage of a concentrate of marigold as a trademark shading, which is antibacterial and antimicrobial. The marigold extract ability was focused on colouring of the cotton fabrics. Investigations of the dye ability, wash fastness, light fastness, antibacterial tests and antimicrobial tests can be endeavoured. Studies have exhibited that surface concealing was not impacted by washing and drying in the shadow/sunlight. These surprises reveal that the concentrate of marigold extract can be used for cotton fabrics.

Prospective Application

The main drawback with microorganism's development on fabrics is associated with the maintenance of hygiene and fabric deterioration. In this present investigation a trial has been made to produce an attractive and vibrant textile with eco-friendly antimicrobial dyeing by marigold, a natural resource. Tagetes erecta universally recognized as Marigold is a remarkable source of carotenoids and lutein, grown as a lawn plant. Now a day, lutein is exploding into an indubitably predominant active fitting, employed as an element of the Drugs, Nutrients and Textile Industry. The prospective application of marigold as a characteristic of antimicrobial activity has not been accustomed fully. It is due to the lack of knowledge about its ability and resemblance in material manner. In this work, we have concentrated on the analysis, which was led to deliberate the use of distillate isolate of marigold as an antimicrobial. The antimicrobial competence of the extract was evaluated by coloring on cotton textiles. Testing of the dye ability, its wash quickness and light fastness was done. Educations have validated that antimicrobial coatings have not affected by laundering and shown enhanced colouring effect comprising of fastness to washing, perspiration and rubbing than conservatively dyed textiles. It revealed that the essence of Marigold flower is habitually employed for cotton fabrics as an antimicrobial finish. The samples show very encouraging ends up in terms of antimicrobial resistivity.

This case study follows the entrepreneurial journey initiated by a group of undergraduate students in the United Arab Emirates (UAE) and examines the decisions made and lessons learned along the way. Uncovering the intricacies of the process of business ideation, the case analyses the predisposing conditions that led to the establishment of the Bulb’s Station—a vending booth offering exclusively homemade food. A particular emphasis is placed on analysing the two major experiences that the partners had running the booth, namely, at the 2016 AUS Global Day and the 2016 UAE National Day Celebration at the American University of Sharjah (AUS). By providing detailed information regarding the type, variety, quantity and pricing of dishes on the menu, the reader is brought to estimate the extent to which the booth’s operation was successful at each of the two events. Based on prior challenges and shortcomings in adopted strategies, the partners are now confronted with the critical question of whether to turn the Bulb’s Station into a start-up company in the food industry in the UAE.

Listeria monocytogenes is a foodborne pathogen responsible for about 1600 illnesses each year in the United States (US) and about 2500 confirmed invasive human cases in European Union (EU) countries. Several technologies and antimicrobials are applied to control the presence of L. monocytogenes in food. Among these, the use of natural antimicrobials is preferred by consumers. This is due to their ability to inhibit the growth of foodborne pathogens but not prompt negative safety concerns. Among natural antimicrobials, plant extracts are used to inactivate L. monocytogenes. However, there is a large amount of these types of extracts, and their active compounds remain unexplored. The aim of this study was to evaluate the antibacterial activity against L. monocytogenes of about 800 plant extracts derived from plants native to different countries worldwide. The minimal inhibitory concentrations (MICs) were determined, and scanning electron microscopy (SEM) was used to verify how the plant extracts affected L. monocytogenes at the microscopic level. Results showed that 12 of the plant extracts had inhibitory activity against L. monocytogenes. Future applications of this study could include the use of these plant extracts as new preservatives to reduce the risk of growth of pathogens and contamination in the food industry from L. monocytogenes.

Kinetics Of

Most of the cotton fabrics at present are dyeing using reactive dyes which requires large quantities of salt, further produce large amount of effluent load to the environment in the form of more salinity in the effluent water along with other pollutants. In order to reduce the salinity in the waste water lot of investigations were carried out. Cotton fabrics pretreated with chitosan were dyed with reactive dyes. Pretreated samples were dyed without using salt as an electrpolyte. The influence of pretreatment on kinetics in dye bath i.e rate of dye particle movement towards the fabric, wash fastness, rubbing fastness was determined. The results of this study shows that the pretreatment of cotton with chitosan increases dye uptake and shows good fastness to washing and rubbing same as that of conventional way of dyed samples. It was determined that chitosan was effective cross linking agent in salt-free dyeing of cotton fabrics.

The Impact

Purpose Sulphur dyes are the most highly consumed colourants for cellulosic substrates owing to their reasonable cost and acceptable fastness. However, the use of noxious conventional reducing agent, sodium sulphide and impaired wash fastness against oxidative bleaching is gradually decreasing the market of these dyes. As the need for “Green” goods and services is raising public awareness, this paper aims to use a glucose-based biodegradable reducing agent in place of sodium sulphide to dye cotton fabrics with a range of commercial sulphur dyes. The study also proposes an aftertreatment method to improve the fastness properties of the dyeing. Design/methodology/approach The paper investigated the impact of a newly developed aftertreatment method on the fastness properties of dyeing. This involved the sequential application of a cationic fixing agent (Tinofix ECO) and tannin (Bayprotect CL) on the coloured fabrics and subsequent evaluation of colour strength, washing, light and rubbing fastness. Findings The effect of aftertreating the dyed cotton was found to significantly improve the light and wet rub fastness. The surface morphology of the dyeing remained unaffected as depicted by the absence of any finish residues. Research limitations/implications The protective effect of the cation–tannin aftertreatments was examined with a view to providing the necessary commercial performance; however, it was established that the dry rub fastness was either reduced or remained unaffected and the wash fastness to International Organization for Standardization 105 C09 was also marginal. Originality/value This finishing technique is novel and can be found useful for manufacturing sulphur-dyed products with the improved light and wet rub fastness.
