Crystal and molecular structures of raw bivoltine silk fibre—A comparative study

S S Mahesh & R Somashekar

Received 18 January 2006; revised received and accepted 14 September 2006

Crystal and molecular structural analysis of raw bivoltine silk fibre  (Bombyx mori) has been made using Linked-Atom Least-Squares technique. It is observed that the unit cell consists of four molecular chains with the space unit cell parameters (a=9.4Å, b=9.2Å and c(fibre axis)=6.97Å with b=90o) and the space group P21. The molecular modification is essentially same as b-pleated structure with antipolar-antiparallel arrangements formed by hydrogen bonds. The essential differences observed in structure, such as intermolecular distance and fractional coordinates, are discussed in detail in comparison with crystal structure of raw pure Mysore silk fibres.

Influence of material parameters and thermal treatment on structure and properties of polyester air-jet spun yarn

Sudipta S Mahish, S K Punj & Gagandeep Singh

Received 7 March 2006; revised received and accepted 15 June 2006

The effect of thermal treatment (dry and wet) under slack conditions, blend ratio and fibre cross-section on the structure and properties of air-jet spun yarns has been studied. It is observed that the thermal treatment, particularly in wet condition, increases the linear density, helix angle, helix diameter, breaking extension and abrasion resistance and decreases the mean fibre extent, tenacity and flexural rigidity of the yarns. The increase in amount of coarser denier fibre exhibits higher helix diameter, mean fibre extent, yarn tenacity, breaking extension, abrasion resistance and flexural rigidity, and lower helix angle. The increase in trilobal fibre content in the blend shows increased helix diameter and mean fibre extent, and lower helix angle, yarn tenacity, breaking extension, abrasion resistance and flexural rigidity in the yarn.

Wicking behaviour of regular ring, jet ring-spun and other types of
compact yarns

S N Subramanian,, A Venkatachalam & V Subramaniam

Revised received 28 February 2006; accepted 23 May 2006

The wicking behaviour of a series of regular ring, jet ring-spun and other types of compact yarns produced by Rocos and Elite systems has been studied. A total of 36 yarn samples with three linear densities have been produced from 100% cotton, scoured and then tested using vertical wicking test; no dye is used in the wicking studies. Compact yarns show lower wickability compared to conventional ring-spun yarns which is attributed to their greater packing density. Washburn’s equation is obeyed quite well when the time constant is near 0.5. In view of the fact that the time constants for Elite and Rocos compact yarns are exceptionally higher than those of jet ring-spun yarns, these can be considered as measures of compact yarns.

Fibre migration in compact spun yarns: Part II – Mechanical compact yarn

 

S Ganesan, A Venkatachalam & V Subramaniam

Received 6 December 2005; revised received and accepted 1 August 2006

Fibre migration of ring and mechanical compact spun combed cotton yarns (40s Ne) has been studied using the tracer fibre technique. It is observed that the migration parameters for compact yarn made from Mechanical Compacting System (MCS)–positive nip are 10-15 % lower than that of the ring yarn and similar to that of pneumatic compact yarn of the same count. However, only a marginal reduction (2-6%) is observed in migration parameter for compact yarn made from MCS–semi-positive nip as compared to ring yarn and it is not significant. Significantly lower degree of migration is observed in mechanical compact yarn spun from MCS–positive nip than in ring yarn due to the significant reduction in size of the spinning triangle in the system and its consequence in the tension gradient. In the case of MCS–semi-positive nip, the base of the spinning triangle remaining the same, its altitude increase causes slight reduction in tension gradient, resulting in marginal change in migration parameters. Yarn diameter of mechanical compact yarn from MCS–positive nip system is found to be significantly lower than that of ring yarn and similar to pneumatic compact yarn, which contributes to increase in strength by 10-15%. The yarn from MCS–semi-positive nip system has shown a marginal reduction in yarn diameter and hence the increase in strength is marginal (3-5%).

Balanced two-ply cotton rotor yarn

N K Palaniswamy, A Shabeer Mohamed & P William Robert

Received 19 April 2006; revised received 30 June 2006; accepted 3 August 2006

Ply twist required to produce balanced two-ply cotton rotor yarn has been measured by placing the two-ply yarn freely in water. When the two-ply yarns are placed freely in water, the ply twist remaining in the yarn is about 40-45 % of single yarn twist, irrespective of ply-to-single yarn twist ratio used for the production of yarn. The twist liveliness of two-ply yarns both in dry and wet states increases as the ply-to-single yarn twist ratio increases. The ply yarn with 45% of single yarn twist shows the lowest amount of snarling twist both in dry and wet states. The fabrics produced using the two-ply yarn with 45% of single yarn twist show negligible amount of spirality in both dry and wet relaxed conditions.

Support vector machines for predicting worsted yarn properties

 

Zhi-Jun Lü, Jian-guo Yang, Qian Xiang & Xiao-ling Wang

Received 18 November 2005; revised received and accepted 11 April 2006

Support vector machines (SVMs) models have been presented for predicting worsted yarn properties using SVM regression algorithms. Model selection which amounts to search in hyper-parameter space is performed to study the suitable parameter conditions. The predictive powers of the SVM models have been estimated and the results are compared with ANN models. It is observed that under the small population circumstances, SVM models are still capable of maintaining the stability of predictive accuracy, and more suitable for noisy and dynamic spinning process.

Disc swirl spinning — A novel approach

 

Mingqiao Ge, Wenyan Gu, Minfa Yuan & Yonggui Li

Received 29 March 2006; revised received and accepted 21 September 2006

A new spinning method ‘disc swirl spinning’, which consists of a combing roller drafting device, funnel fibre conveyer, disc fibre collector and swirl twister, has been developed. The spinning process, the design of the mechanism and its applications have been described and a preliminary comparative performance of the yarn quality analyzed. Scanning electron microphotographs of the disc swirl core-spun yarn have been compared with those of the air-jet spun and rotor-spun yarns. It is observed that the appearance of disc swirl core-spun yarn is similar to that of rotor-spun yarn, while the inner structure of the disc swirl core-spun yarn is found similar to that of the air-jet spun yarn. The breaking strength of disc swirl core-spun yarn is little lower than that of the ring core-spun yarn, while its breaking elongation CV% is higher. The other quality parameters of the two kinds of yarn are found to be similar. The quality of the disc swirl core-spun yarn can basically meet the need of the processes.

Optimizing the frequency of oscillating beater in double roller gin

S B Jadhav & K M Paralikar

Received 17 July 2006; revised received and accepted 14 September 2006

Variable speed double roller gin has been used to optimize the frequency of oscillating beater, considering three levels of oscillating frequency, namely 750, 1000 and 1250 cpm and conventional frequency of 1000 cpm. The factors considered for optimum rates include lint turn out, fibre quality and ginning rate. Overall, the fibre quality remains unaffected for all types of cottons, whereas the lint out-turn and ginning rate are found to be highest at 1250cpm frequency for long and extra long staple cottons. The conventional frequency is found to be better for short staple cottons. The short fibre content, seed coat neps and neps in the lint are comparatively less at higher frequency.

Dynamics analysis and testing in air-jet weft insertion

 

Danfeng Shen & Guoming Ye

Received 13 March 2006; revised received and accepted 11 August 2006

On the basis of fluid dynamics, this paper deduces the pull force formula of main nozzle on air-jet loom and introduces a method of experiment to test the airflow velocity in the exit of nozzle. The effect of different structure parameters of main nozzle on the pull force has been studied. It is observed that the inlet of thread tube is a bottleneck of main nozzle and the main development of main nozzle lengthens the thread tube. The theoretical findings are found to be in good agreement with experimental findings and this verifies that the formula for pull force is reasonable.

Effect of processing parameters on properties of layered composite needle-punched nonwoven air filters

V K Kothari, A Das & A Sarkar

Revised received 18 May 2006; accepted 16 June 2006

Layered composite needle-punched nonwoven fabrics have been prepared using 6 den and 15 den polyester staple fibres separately and in 50:50 proportion and their air filtration and other associated properties studied. Processing parameter such as punch density has also been altered to investigate its effect on filtration efficiency as well as on associated properties like dimensional stability, air permeability, compression-recovery, tensile strength, abrasion resistance and friction. Filtration efficiency values show an initial rise and then subsequent fall with incremental punch densities in case of layered fabric and those made with fine fibres. In case of coarse fibre, however, the values continue to increase with punch density. The pressure drop required to maintain a certain level of flux of air through the fabrics is also not too high as that of fine fibre fabrics. Dimensional stability of fabric layered with 50:50 proportion of 6 and 15 den fibres is also found to be higher as compared to that of the fabrics of other combinations. Compression / recovery performance of layered fabric is also found to be better. All these positive attributes of the blended 6 and 15 den (50:50) layered fabrics show that the composite needle-punched fabrics will perform better as air filters.

Efficacy of nonwoven materials as sound insulator

M D Teli, A Pal & Dipankar Roy

Revised received 17 May 2006; accepted 10 July 2006

Nonwoven materials of various origins have been studied in terms of their efficacy in reduction of sound using tube set-up. Various parameters, such as frequency of sound generated, distance between sound generator and sample, and physical features of samples (air permeability, thickness and GSM), are studied with reference to effectiveness of sound reduction of these fabrics. The sound reduction is also measured using another method resembling real life situation. It is observed that with the increase in frequency and GSM the extent of sound reduction increases while with the increase in air permeability, the extent of sound reduction by the material decreases. Although the extent of sound reduction values slightly differs, the order of efficacy of various nonwoven fabric samples indicated by both the techniques remains the same. This study enables the users to select an efficient material to be used in noise control.

Theoretical model on mass of soil particles passing through two-layered nonwoven geotextile

Li Fang Liu

Revised received 26 June 2006; accepted 6 September 2006

A two-layered nonwoven geotextile, associated with one layer of fine fibres having a thickness selected to provide optimal filtration characteristics and another layer of coarse fibres to provide the required mechanical properties, has been developed to study its theoretical filtration performance. Based on the theoretical filtration of single layer nonwoven geotextile, a mathematical model on mass of soil passing through two-layered nonwoven geotextile is established. The model is validated by slurry test using a self-designed apparatus. The experimental results obtained for five different specimens are compared with the theoretical solution, and it is found that the present model predicts to an accuracy of about 93.2% for needle-punched two-layered nonwoven geotextiles.

Filtration behaviour of woven and nonwoven fabrics

V K Kothari, A Das & S Singh

Received 11 April 2006; accepted 24 July 2006

The filtration behaviour of woven and nonwoven fabrics at different air flow rate, dust feed rate, dust loading, time intervals and dust particles has been studied. It is observed that the pressure drop increases with the increase in airflow rate for both the woven and nonwoven filters. In general, the pressure drop in case of woven filter is found to be higher than that in case of nonwoven filter. In case of woven fabric, in general, the filtration efficiency and the pressure drop increase with the time interval, but the rate of increase is found to be different for different types of dust particles, i.e. the distribution of size of dust particles. The cleaning efficiency of woven filter in case of clay is found to be lowest followed by sand and Sipernat mixture. The outlet dust concentration in case of woven filter reduces with the time and in case of clay it is highest as compared to the other dust particles. In case of nonwoven filter, with the increase in air flow rate the increase in pressure drop is found to be more at constant dust loading than that at constant dust feed rate. The filtration and cleaning efficiencies of nonwoven fabric, for a certain type of dust particle, are found to be affected by the dust feed rate and the air flow rate.

Hydrogen peroxide and potassium per-oxo-disulphate combined room temperature bleaching of jute, cotton and jute-cotton union fabrics — An energy-efficient ecofriendly process

A K Samanta, Deepali Singhee, G Basuc & K K Mahalanabis

Received 23 January 2006; revised received and accepted 10 July 2006

A method for room temperature bleaching of jute, cotton and jute-cotton union fabrics using a combination of H2O2 and K2S2O8 has been optimized. The measurement of physical properties, such as breaking tenacity, weight loss and surface appearance, including SEM study indicates that the proposed room temperature bleaching process is less damaging to the three types of fabrics studied as compared to conventional hot (85oC) H2O2 bleaching. The whiteness index is within the acceptable range. The suggested reaction mechanism indicates that K2S2O8 acts as a peroxide booster showing a synergistic action. This room temperature bleaching process is energy efficient, ecofriendly and economical, which can be easily adopted by both small scale and large scale sectors.

Dyeing kinetics of radiation-grafted polyester fabric using different dyes

E H El-Gendy ,  N M Ali , M M Marie & I A El-Shanshoury

Revised received 17 June 2006; accepted 20 July 2006

Dyeing kinetics of radiation-grafted and ungrafted polyester fabrics using basic, direct and disperse dyes have been studied in the temperature range 283-363 K and then compared. The effects of graft yield, pH of the dye solution, dyeing time, dye concentration and dyeing temperature on the colour difference of ploy (ethylene terephthalate) fabric have been studied for basic Rhodamine Red, direct Congo Red and Disperse Red dyes. The colour difference increases rapidly with the increase in graft yield and tends to level off at higher degrees of grafting. The best dyeing conditions are achieved at pH 9, 5.5 and 5.5 for direct, basic and disperse dyes respectively. The kinetic parameters (rate, rate constant, order, activation energy and pre-exponential rate constant) have also been evaluated for the different dyes. Analysis of the kinetic parameters and dyeing mechanisms reveals that the dyeing of polyester fabric is diffusion-controlled, and the dyeing rates follow the order: basic dye (1% grafted) >> direct (1% grafted) > disperse (1% grafted) > disperse (with a carrier) > disperse (without a carrier). Grafting improves significantly the dyeing affinity of polyester fabric towards basic, direct and disperse dyes.

Effect of enzyme softening of cotton hosiery yarns on knittability and dimensional properties of weft knitted fabrics

Bhaarathi Dhurai &  V Natarajan

Received 25 October 2005; revised received and accepted 12 June 2006

Enzyme softening of cotton hosiery ring carded, ring combed and rotor yarns (19.68 tex) has been carried out using commercially available Bio-soft L+ acid type cellulase enzyme at optimized conditions. Knittability of enzyme-softened yarns has been studied and compared with their respective waxed yarns by measuring the actual loop length of knitted fabrics produced under different input tension and by maximum tight structure possible to knit in the given machine. It is observed that the enzyme softening improves the knittability of all three types of yarns to a significant level; the knittability of ring carded yarn improves to the level of ring combed yarn. Enzyme-softened rotor yarn shows the better knittability than enzyme-softened ring carded and combed yarns. The enzyme softening of yarn also increases the dimensional stability of single jersey fabric to a remarkable level. Among the enzyme-softened ring carded, ring combed and rotor yarns, the dimensional stability of ring combed yarn fabric is found to be very good. Changes in mass per unit area and thickness remain almost unaltered after wet relaxation treatments in case of enzyme-softened yarn fabrics.

Effect of silica and calcium carbonate fillers on the properties of woven glass fibre composites

S P Borkar, V Senthil Kumar & S S Mantha

Revised received 2 March 2006; accepted 28 November 2006

The effect of silica and calcium carbonate fillers on the properties of woven glass fibre composite has been studied with an attempt to observe the amount of property loss due to replacement of expensive resin by cheap fillers. The silica and calcium carbonate fillers of the amount 25% and 50% respectively of the weight of the resin have been used and the properties, namely tensile strength, flexural strength and impact strength, studied. It is observed that the impact and tensile strength slightly reduce but the flexural strength significantly increases.
