The main aim of this research is to apply the functional finishes to denim garments to enhance the value of the garment. The fabric selected for the research is 100% cotton with the construction of 2/1 Right Hand Twill. The selected fabric was made into garments (A-line frock) and subjected to de-sizing and enzyme washing and then the garments were treated with two different synthetic scents sweet citrus and rose oils to induce fragrance. The garments were also tested for the efficacy of anti-microbial, antifungal, UV protection, stain repellency and mosquito repellency finishes. The results have proven very good sense of functional finishes on to the garments in conjunction with a sweet fragrance. Two different methods – dip dry and micro encapsulation methods were chosen for the study and the fastness property of the finishes were compared. The treated garments were evaluated using AATCC standards. Keywords: fragrance finish; anti-microbial finish; anti-fungal finish; A-line frock; enzyme washing.   DOI: http://dx.doi.org/10.3329/diujst.v7i1.9649   Daffodil International University Journal of Science and Technology Vol.7(1) 2012 59-66

In the quest to develop more innovative customer-focused library services, the Botswana International University of Science and Technology (BIUST) Library embarked on the development of robust initiatives that involved the engagement of various stakeholders. The emerging consultative and engaging trend is premised on the key values of facilitating access to information and demand-driven inclusive library services. The paper presents how the BIUST Library engages stakeholders in the development of multiple and flexible opportunities to access and use information. In doing so, it describes the recreation of internal library structures, space, and processes in a way that accommodates and demonstrates the categories and functional roles of different types of library stakeholders. The paper further points to how the stakeholders’ cultures and systems create a divide or imbalance in the access and usage of library services. The paper also argues for a need to define library stakeholders and develop engagement strategies that are entity and initiative specific.

Alum Treatment

To produce hydrophobic handmade paper internal material rosin along with external additive (MCC suspension), internal additive (wax emulsion) and reinforcement were used. Optimum result was obtained when rosin along with alum was used as internal additive during pulp preparation and MCC in the form of suspension was applied as external additive. The hydrophobicity was increased by 92.46% due to rosin-alum treatment and application of MCC suspension as external additive. It was also observed that application of wax along with rosin hampered/hindered the hydrophobicity.

Washing is one of the most important finishing treatments applied on apparels that have great usage to create special outlooks and improving the fashion. Technologically denim washing is the most important fashion element for clothing industry. Usually the term ‘washing' is most significantly applied in case of sewn apparels so it is very essential to observe the effects that have been made by particular washing on the fabrics to hold the qualities of sewn apparels. The aim of this paper is to determine the effects of sand blasting with industrial enzyme silicon wash on denim apparel characteristics. For this investigation currently fashionable regular denim (100% cotton with twill 3/1 weave construction) trouser was chosen. The selected denim trouser has been processed by enzyme and silicon washes after sand blasting. In order to evaluate the washing effects on denim trouser, changes of fabric handle, fabric specification (ends/inch, picks/inch, surface density, warp & weft yarn linear density), fabric strength, seam strength & fabric stiffness has been determined after sandblasting with enzyme silicon wash. Keywords: Denim apparel, sand blasting, back staining, pumice stones, enzyme wash.   DOI: 10.3329/diujst.v5i1.4377 Daffodil International University Journal of Science and Technology Vol.5(1) 2010 pp.6-9

A research had been taken to find out the suitability of blended curtain in respect to the property of 100% similar cotton curtain. Here, two main factors viz. wt. and strength are taken in to account considering the effect of washing on it. From the test results, it is shown that 50:50/ jute: cotton blended curtain is comparable to the 100% cotton curtain of Tk. 90 /meter. Even better than the properties of 100% cotton curtain of Tk. 60/ meter.

An edge-ranking of a graph G is a labeling of its edges with positive integers such that every path between two edges with the same label i contains an intermediate edge with label j>i. The minimum edge-ranking spanning tree problem is to find a spanning tree of a graph G whose edge-ranking needs least number of ranks. In this paper, we present an algorithm to solve the minimum edge-ranking spanning tree problem on a partial k-tree G in O(n2Δ(k+1)+2 Δk(k+1)+2 log2 k(k+1)+2n) time, where n is the number of vertices, Δ is the maximum vertex degree of the graph G and k is bounded by a constant value. Keywords: Algorithm, partial k-trees, edge-ranking, spanning tree. DOI: 10.3329/diujst.v4i1.4347 Daffodil International University Journal of Science and Technology Vol.4(1) 2009 pp.1-8

Synthetic dyes and all the processing used in general dyeing is harmful to our health. Dye from natural sources can reduce the risk of synthetic dyes. As indigo has been used for thousands of years for the coloration of textiles as a natural source. This review is aimed at a discussion of different raw materials used for the extraction of natural dyes, the extraction process for different natural dyes, and the properties of fabric dyed by those dyestuffs. Most of the natural dyes showed a very good fastness property in researches. The dyes can be extracted from trees, bark, leaves, flowers, and many more sources. Most of the natural dyes exhibit special properties like anti-microbial, less toxicity, less allergenic, UV protection.
