Purpose – The purpose of this paper is to develop a 3D geometric model of three-pick terry fabric considering the actual design and structural features of the finished terry fabric. Design/methodology/approach – The model has been developed using SolidWorks CAD system and the output file can be easily simulated in the ANSYS. Dimensions are acquired from the actual terry fabric measurement. Findings – A 3D computational model – to be used for understanding the behaviour of terry fabric during actual use through the simulation in ANSYS. Practical implications – Provides the way to study the yarn and fabric structure behaviour during use through simulation. Originality/value – The research resulted a 3D geometrical model of very complex three-pick terry fabric for very first time for further analysis of terry fabric behaviour during use. ©Emerald Group Publishing Limited.

A study was conducted to enhance the value of linen fabric with resist printing using vat dyes and different resisting agents. Printing paste was prepared by mixing the vat dye in cold water and then potassium carbonate was added in this dye paste. The mixture was heated at 70°C for 20 mm to dissolve the dye and the solution obtained is then stirred with the help of electronic stirrer into the thickening. Visual evaluation was carried out through a panel of 30 judges. The attributes for evaluation were uniformity in color, sharpness of outlines, overall appearance and bleeding on ground. The negative DL value indicates the darkness of color and positive DL value indicates the lightness of the color. Linen samples printed with 16.0% concentration of different resisting agents were considered as standard for measuring the DL value of all other samples.

Attempts have been made to develop natural dye based antimoth finishing process using natural dyes as an alternative of chemical based process. Natural dyes obtained from different sources are used to dye the woollen fabric and then screened for antimoth efficacy. Woollen fabrics dyed with extract of silver oak leaves, wall nut husk and pomegranate rind have shown highest resistance to moth attack. The screened sources carrying antimoth property are then subjected to phytochemical analysis along with non-carrying natural dyes for analyzing their chemical constituents. The result reveals that the chemical constituent of natural dyes plays a crucial role in determining antimoth efficacy. The amount of tannin content present in the natural dyes can be taken as an indicator to determine the antimoth efficacy. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

In this paper, a critical review of the evolved theories and mechanisms of water absorption in terry fabric has been reported along with the key factors to improve the water absorption. Critical analysis of all the information helps to understand and choose the most realistic theory and mechanism of water absorption of terry fabric which will be helpful in designing the most absorbent terry fabric. Both dynamic and static water absorbency along with the initial time lag immerse to be the equally important attributes of the water absorbency performance of terry fabrics. High loop shape factor is the key to improve the absorbency behaviour of the terry fabric. Study of cross-section images of different fabric is the original work of the authors for supporting the concluding theory, mechanism and results. © 2015 National Institute of Science Communication and Information Resources (NISCAIR).

Fabric compression is a decrease in intrinsic thickness with an appropriate increase in pressure. The compressibility of the terry fabric depends on fibre properties, yarn parameters, weaving parameters, loop length, loop density, loop geometry and post-weaving treatments. In this research, all the factors responsible for fabric compression have been studied. It is observed that loop density, loop length, loop-shape factor, pile yarn twist, pile yarn count, fibre length and pile yarn structure have a significant effect on the compression behaviour of the terry fabric. With increase in the loop-shape factor, loop length and loop density, the linearity of compression curve, resilience increases and specific compression energy reduces which depict that the fabric is getting better in terms of softness to touch. It is also observed that pile yarns produced from ring spinning, zero twist, MCU-5 cotton, porous yarn and finer yarn produce better terry fabric in terms of compression behaviour and surface properties. The loop geometry modelled in the form of shape factor correlates with the compression of the fabric. The research also helps to design a towel by controlling loop geometry. © 2014 The Textile Institute.
