Effect of process parameters and blend percentage on physical properties of polyester/viscose blended air-jet textured yarns

S S Mahish , S K Punj & V K Kothari

Received 10 April 2007; revised received and accepted 30 August 2007

The effect of air pressure, overfeed and varying blend percentage on the properties of the polyester/viscose blended air-jet textured yarns has been studied. It is observed that at lower air pressure and overfeed levels, the increasing texturing speed reduces physical bulk and at higher texturing speed the increasing overfeed increases physical bulk. Physical bulk increases with the simultaneous increase in overfeed and air pressure and it reduces with a combination of low overfeed and high texturing speed. A combination of high texturing speed and low air pressure generates lower instability in the textured yarn.

Study on cotton ring and OE rotor yarn characteristics:
Part II – Effect of caustic and enzymatic scouring treatments on structure
and recovery characteristics

G K Tyagi & Dhirendra Sharma

Received 31 January 2007; revised received and accepted 15 June 2007

The effects of scouring treatments on the structural and recovery characteristics of cotton ring- and rotor-spun yarns have been studied. In general, ring yarns have high mean fibre extent, spinning-in coefficient, immediate elastic recovery and delayed recovery, and less permanent set than the rotor-spun yarns. The results show that the scouring produces high immediate elastic recovery and delayed recovery but reduces permanent set, irrespective of the yarn structure. Although a greater effect is obtained with caustic scouring than with enzyme scouring, the magnitude depends mainly on processing factors. The structural properties reasonably reduces for different types of scouring treatments.

Dual antimicrobial and blood repellent finishes for cotton hospital fabrics

 

G Thilagavathi & T Kannaian

Received 18 April 2007; revised received 13 July 2007; accepted 18 September 2007

Antimicrobial and blood repellent finish has been applied to cotton fabrics used for surgical gowns, bed linens and drapes to reduce the surgical site infections. The extract of neem was applied to the fabric for imparting antimicrobial activity by pad-dry-cure method. The neem treated fabric was then imparted blood repellency through two different techniques, namely by treatment with fluoropolymer (3%, 4% and 5% owf) using pad-dry-cure method and by ‘sputter deposition of teflon’ technique using argon plasma. The antimicrobial activity is found to be higher for teflon deposited fabric than for the fluoropolymer finished fabric. Blood repellency increases with the higher concentration of fluoropolymer and the highest repellency for the teflon deposited fabric is observed at 80W power and 20 min exposure in the plasma chamber.

Use of jute needle-punched nonwoven fabric as reinforcement in composite

Surajit Sengupta, Sambhu Nath Chattopadhyay, Soma Samajpati & Abhindra Day

Received 25 January 2007; revised received and accepted 19 July 2007

The effect of punch density, depth of needle penetration, fibre orientation and area density of jute needle-punched nonwoven fabric, for use as reinforcing material in jute-reinforced plastic (JRP) composite, has been studied and the composite properties, such as tensile strength and modulus, flexural strength and modulus, and impact strength optimized. Composites have been prepared using hand lay-up technique with polyester resin. The fabric made with optimized parameters has been chemically treated and the mechanical properties of its composite evaluated. It is observed that the cross-laid nonwoven produces better composite, considering its mechanical properties in the machine and cross directions, compared to parallel-laid nonwoven. Jute nonwoven with 10 mm depth of needle penetration, 250 punches/cm2 punch density and 700 g/m2 area density shows optimum mechanical properties of the composite. On comparing the properties of nonwoven composite with those of the composite made out of woven jute fabric, it is observed that the nonwoven fabric shows better properties than woven fabric. Chemical treatment further improves the properties. Bleaching of nonwoven fabric with H2O2 shows optimum properties among the different chemical treatments applied to the fabric.

Simulation analysis of weft yarn motion in single nozzle air-jet loom to study the effective parameters

 

H Nosraty, Ali A A Jeddi & Y Mousaloo

Received 25 July 2007; accepted 14 February 2008

A simulation model has been suggested for a single nozzle air-jet loom to analyse weft yarn motion under different conditions of weaving procedure. For this purpose, weft yarn motion equation has been derived using this model, physical laws and combination of air velocity and air-yarn friction coefficient equations. This analytical model for drum storage system is developed to investigate the weft yarn behaviour during weft insertion, i.e. displacement, velocity, and yarn tension. Numerical solutions of yarn motion equations have been obtained. Tension analysis of weft insertion has been carried out both theoretically and experimentally using different cotton-polyester yarn counts under different air pressures. The results show good agreement between theoretical and experimental values of weft yarn tension.

Ecofriendly discharge printing on cotton fabrics using laccase enzyme

 

I Abd El-Thalouth, F Kantouch, S H Nassar,  H M El-Hennawi & M Adel Youssef

Received 13 April 2007; revised received and accepted 10 September 2007

Laccase enzyme formulation has been used in discharge printing of cotton fabrics dyed with different reactive dyes and the effect of enzyme conc., pH of the printing paste, treatment time and temperature of enzymatic treatment as well as the viscosity of the printing paste on colour discharge studied. The optimum conditions for discharge printing are found to be 4.5 pH, 60°C temperature, 1 h time of treatment, and the 90.4 poise viscosity at a shear rate of 31.61s-1. The concentration of enzyme depends on the nature of dye used.

Md. Shamsul Alam, G M Arifuzzaman Khan, S M Abdur Razzaque, M Jamil Hossain,  M Minhaz-ul-Haque & Sonia Zebsyn

Revised received 21 May 2007; accepted 7 September 2007

The effect of dye concentration, electrolyte concentration, dyeing time and dyeing temperature on dyeing performance of cotton fabric dyed with reactive dyes, viz. Reactive Red 6B and Reactive Yellow RL, has been studied. The dye absorption increases with the increase in electrolyte concentration, dyeing time and dyeing temperature but decreases with the increase in dye concentration. Considering the effects of various external influences on the dyed cotton fabric, it has been observed that the Reactive Yellow RL imparts better physico-chemical properties than Reactive Red 6B in most cases.

Physico-chemical studies on dyeing of jute and cotton fabrics using jackfruit wood extract: Part II — Dyeing kinetics and thermodynamic studies

 

Ashis Kumar Samanta,  Priti Agarwal & Siddhartha Datta

Received 7 August 2006; revised received and accepted 30 November 2006

Bleached jute and cotton fabrics have been double pre-mordanted applying 20% myrobolan (harda) as 1st mordant and 20% Al2(SO4)3 or 20% FeSO4 as 2nd mordant and subsequently dyed with aqueous extract of jackfruit wood under optimized conditions of dyeing. The physico-chemical parameters of dyeing, such as dyeing affinity, rate of dyeing, absorption isotherms and associated thermodynamic parameters like heat of dyeing (∆H), entropy of dyeing (∆S) and Gibb’s free energy (∆G), have been assessed to explain the interaction among different fibre-mordant-dye systems. It is observed that all of these dyeing processes are endothermic, ∆H values being positive. Among different fibre-mordant-dye systems studied, jute fabric double pre-mordanted with harda and FeSO4 shows a non-linear Langmuir type dye-absorption isotherm, while dye-absorption isotherms of all other fibre-mordant-dye systems are found to be linear following Nernst absorption isotherm, indicating the formation of co-ordinated complex in jute-harda + FeSO4 –dye sample, and hydrogen bonding in all other cases of fibre-mordant-dye systems studied. However, the negative ∆G values of all the systems studied indicate that the potentiality of chemical interaction /reaction of these fibre-mordant-dye systems in some otherwise favorable conditions of dyeing need to be further studied.

Effluent treatment in textile wet processing —Bleaching of
polyester-cotton fabric

 

A I Wasif, S K Chinta & H T Deo

Revised received 9 April 2007; accepted 21 June 2007

Ecofriendly processes have been developed for the bleaching of carbonized and uncarbonized polyester-cotton blended fabrics with a view to reduce the water consumption and processing time. There is no significant difference in the whiteness values, K/S values and fastness properties of samples bleached by the conventional method and those bleached by the two suggested formulations. Further, by employing ecofriendly processes, there is significant decrease in volume of effluent generated. Both the formulations are found to be techno - economically viable.

Effects of repeated home launderings and non-durable press on the colour properties of plain woven polyester fabric

 

Muruvvet Mangut, Behcet Becerir & Halil Rifat Alpay

Received 8 May 2007; revised received and accepted 9 October 2007

The colour values and colour differences occurred in dyed polyester fabrics after repeated home launderings and non-durable pressings (hot-pressing) have been assessed. Two disperse dyes with different chemical structures (azo and anthraquinone) were applied to the polyester fabric separately at different dyeing concentrations and the domestic ironing was simulated by using international hot-pressing standards. The K/S value, lightness (L*), chroma (C*) and colour differences (DE*) were measured for the repeated experiment cycles. It is observed that the K/S values slightly decrease and L* values gradually increase, indicating the loss of some dyes from the fibres and decreasing depth. C* values increase as the experiment cycles increase. Colour differences are found to depend on the chemical class and concentration of the disperse dyes used, and colour measurement time. Dyeing at low dye concentrations is affected more from the repeated experimental procedure.

A new bio-chemical scouring technique for cotton hand processing units

 

P V Varadarajana, R H Balsubramanya, Nayana D Nachane & R R Mahangade

Received 26 March 2007; accepted 24 September 2007

The cotton woven fabric has been subjected to anaerobic treatment using a mixed microflora at room temperature followed by mild alkali boiling. The required enzymes are produced in situ by a mixture of microflora and hence does not need external supply of costly enzymes. The treated fabric is then peroxide bleached, dyed with hot brand reactive dye and evaluated for various parameters. The results show that the properties of treated fabric are at par with the conventionally processed ones. The colour values of the treated and dyed samples are in fact higher than the conventionally processed ones. The above process can be easily coupled to the existing hand processing units. The new process may result in considerable reduction in pollution load along with appreciable saving in energy.
