Application of Biotechnology in the Colouration of Jute Fabric Using Vinyl Sulphone Type of Reactive Dyes

Pan NC, Chattopadhyay SN, Roy AK, Khan A and Patra K

Two sets of processed jute fabric viz, alkaline scoured-bleached and bioscoured-bleached jute fabrics were dyed separately with two nucleophilic addition type (vinyl sulphone type) of reactive dyes namely, Remazol Yellow FG and Amidazol Brown GR dyes. From the experiment it is revealed that bioscoured-bleached reactive dyed jute fabric shows higher dye uptake than that produced by alkaline scoured-bleached-reactive dyed jute fabric in case of both the vinyl sulphone type of reactive dyes. Biotreatment results in improvement of handle and wash fastness properties of jute fabric. Brightness of the shade was also improved in case of biotreatment-bleached-reactive dyed jute fabric.

Rheological Modeling of the Dorlastan Core Spun Yarns for Various Dorlastan Drafts and Yarn Counts

Helali H, Babay Dhouib A, Msahli S and Cheikhrouhou M

 The mechanical behaviour of the Dorlastan® core spun yarns having different counts (100, 50, 33.33 and 25 tex) and various elastane drafts is modeled in this paper. The theoretical analysis is based on the response of the elastic core spun yarn to the tensile and the relaxation tests at different strain levels. These tests have permitted us to identify the non linear viscoelastic behaviour of the Dorlastan® core spun yarn. Analogical approach is employed to propose the rheological model describing the mechanical behaviour of the elastic core spun yarns. Comparing with the experimental data, the theoretical model gives a reasonably accurate prediction of the mechanical behaviour of the elastic core spun yarns for both tensile and relaxation tests.

Structural Analysis of Cotton/Lycra Corespun Single Jersey Knitted Fabrics

Kathirvel KP and Ramachandran T

 An attempt has been made to analyze the effect and as well as to gain an insight of changing the loop length of the knitted fabric against non-dimensional parameters such as the loop shape factor during different stages of relaxation using corespun cotton/lycra yarn. The yarn count, machine gauge and machine diameter are kept constant but the loop length is varied. Three different structures (Popcorn, Double Airtex and Honeycomb) at 0.106, 0.118 and 0.129 inches loop length for each structure are produced. This study will help to analyze the relationship between loop length and the non-dimensional parameters like Kc, Kw, S, Kc/Kw.

Statistical analysis is done to analyze if there is any significant change in loop shape factor between different relaxed stages and between different loop lengths in a particular fabric structure.

Comparative Study on Antibacterial Finishes by Herbal and Conventional Methods on the Woven Fabrics

Banupriya J and Maheshwari V

 Cotton is the natural vegetable fiber of great economic importance as a raw material for cloth. An eco friendly natural antibacterial finish has been prepared from the plant extract for the textile application. Herbal extracts have been applied to cotton and organic cotton fabric by pad, dry cure method. This paper consists of a detailed discussion of the herbal finish with Antibacterial effect on cotton and organic cotton fabrics .The Antibacterial property of fabrics is considered to be more important and inevitable finish for garments, which are in direct contact with human body.

In this paper the investigators have compared the effect of Antibacterial finish applied by conventional and herbal based methods and the best result among the two processes were analyzed and discussed.
