Compression properties of textile materials are useful for determining fullness, softness, smoothness, and stiffness. In addition, compression parameters have significant influence on fabric hand value and quality of textile materials. The present paper reports a study of the sublimation printing process influence on the change in compression properties of knitted fabrics (polyester, cotton, and cotton/ polyester) intended for sportswear manufacturing. For that purpose, the KES-FB3-A Compression Tester was used for measuring compression parameters of knitted fabrics. The parameters, which contributed to the smallest reduction percentage in compression properties of polyester knitted fabrics were yarn linear density and weight. For cotton-rich knitted fabrics sublimation coating powder was used for paper modification to bond disperse dyes to cotton fibres. The analysis of the results showed that the printing process had a smaller influence on the change of compression parameters of polyesters in relation to cotton and cotton/polyester knitted fabrics. It was noted that the printing process had the effect of thickness reduction for all knitted fabrics to varying degrees. Printing process contributed to small decrease in compressibility and specific volume values for polyester knitted fabrics. The modification process contributed to the significant reduction of the compressibility for cotton (from 34.46% to 47.89%) and cotton/polyester (from 38.81% to 50.75%) knitted fabrics. In addition, reduction in specific volume values range from 41.86% to 44.19% for cotton and from 42.37% to 45.75% for cotton/ polyester knitted fabrics was notted.

Sustainability is the key to responsible production and conservation of environment, which is the need of the hour. Indian motifs based on traditional textile arts and crafts have always been a source of inspiration not only to Indian designers but also have intrigued global designers. These motifs can be adapted into lifestyle products through modern techniques of surface enrichment. Lifestyle products hold a lucrative market in the textile sector. Apron is one such lifestyle product which falls under the category of accessories. This study explores how traditional knowledge of Indian arts and crafts can open up avenues for responsible designing of lifestyle products. In the present study, fifty motifs/designs from textile and architectural sources of Manipur were collected from secondary sources, adapted and simplified for application in kitchen apron using CorelDraw X3 software. Ten adapted designs were selected through visual inspection by a panel of thirty judges. The design arrangements were developed for kitchen apron by preparing line patterns, motifs/designs layout and colourways, respectively. The outcome of every step was visually evaluated by the same panel of thirty judges, except for the line patterns, on five point scale. The prototype scoring highest weighted mean score i.e., rank I was selected for further developing the following consequent steps. The finalized designs were printed on the paper using disperse dyes. The printed papers were then used to transfer designs on the constructed and finished apron made of polyester/cotton blended fabric. The cost of apron was estimated Rs. 244/- which can be reduced if produced in bulk. Consumer assessment was carried out for the printed apron on various aesthetic parameters. Consumers’ acceptance for the printed apron was found high which reflected its marketability owing to uniqueness of the motifs, traditional values associated with the traditional motifs of Manipur, sharpness of design lines, the clarity of prints and the reasonable price. Thus, study outcome revealed that the designs inspired from traditional textile arts and crafts of Manipur can be successfully rejuvenated into lifestyle products through heat transfer printing which is environmentally feasible, socially acceptable and economically viable.

Over 50% of all colorants which are used nowdays are azo dyes and pigments, and among them arylazo pyridone dyes (and pigments) have became of interest in last several decades due to the high molar extinction coefficient, and the medium to high light and wet fastness properties. They find application generally as disperse dyes. The importance of disperse dyes increased in the 1970s and 1980s due to the use of polyester and nylon as the main synthetic fibers. Also, disperse dyes were used rapidly since 1970 in inks for the heat-transfer printing of polyester. The main synthetic route for the preparation of azo dyes is coupling reaction between an aromatic diazo compound and a coupling component. Of all dyes manufactured, about 60% are produced by this reaction. Arylazo pyridone dyes can be prepared from pyridone moiety as a coupling component, where substituent can be on nitrogen, and diazonim salts which can be derived from different substituted anilines or other heterocyclic derivatives. In addition, arylazo dyes containing pyridone ring can be prepared from arylazo diketones or arylazo ketoesters (obtained by coupling ?-diketones or ?-ketoesters with diazonim salts) by condensation with cyanoacetamide. Disazo dyes can be prepared by tetrazotizing a dianiline and coupling it with a pyridone or by diazotizing aniline and coupling it with a dipyridone. Trisazo dyes can be also prepared by diazotizing of aniline and coupling it with a tripyridone or by hexazotizing a trianiline and coupling it with a pyridone. The main goal of this paper is to give a brief review on the synthesis of arylazo pyridone dyes due to the lack of such reviews. In addition, some properties of arylazo pyridone dyes as light fastness and azo-hydrazon tautomerism are disccused.

Abstract The use of sublimation thermal transfer printing onto cotton is not widely practiced because of the lack of disperse dyes affinity for cellulose fibres. The studies were performed onto polymer application on cotton fibres in order to achieve the ability to absorption of sublimating dyes and thus the possibility of making printouts onto cotton. The following parameters were evaluated: whiteness degree after impregnation, the relative strength of colours of the obtained printouts, test washing fastness, and dry and wet rubbing fastness.
