Dear Readers,

I take pleasure in greeting all our readers through this new initiative -

e-Techletter - a bi-monthly publication from SITRA. Commencing this issue,

this news bulletin will replace our regular ‘SITRA News’, which till date was

in the physical form. It is another small step that we are taking as part of our

“Go-Green” initiative.

Taking inputs from our readers, we have tried to give a face-lift to this e

publication by making it more reader-friendly, both in terms of visual feel as

well as coverage of topics. As we evolve, we shall strive to make

e-Techletter more interactive and interesting to our readers.

I am sure that members as well as other regular readers will continue to

enjoy the technical inputs that we will be providing in this publication.

In recent times, we have initiated various organizational reforms aimed at

reaching out to our members. Apart from ensuring betterment of activities

that the organization is involved in, the reforms also encompass a strategic

focus that ensures that SITRA is proactive and sensitive to the needs of the

industry it caters. Each of the service is aimed at adding value to SITRA and

position it as a forerunner to the evolving industry. I am hopeful that the

successful implementation of those measures would greatly help the

Textile Industry in meeting its present and future needs.

MPEI (April 2016 – March 2017)

SITRA has developed an index called “MPEI” which reflects of the cotton spinning industry. MPEI is an arithmetic index that is derived by having April 2013 as the base month and the base index set to 100 for that month. The calculation of MPEI is based on the average net out-put value [yarn selling price – raw material cost] in terms of Rs per kg of yarn for 12 popular counts - 40s K, 40s C, 60s C, 80s C, 100s C, 40s C-Comp., 50s C-Comp., 60s C-Comp., 80s C-Comp., 30s CH, 30s CH-Ex. and 40s CH.

The trend in the movement of MPEI for the past 12 months (i.e. from April 2016 – March 2017) is shown in Figure 1.

During April 2016, the MPEI was low at 76. Thereafter, it started to recover and had reached the level of 82 in July 2016. Since August 2016, the MPEI continued to follow a declining trend up to November 2016 in which it had recorded the lowest value of 70. However, within a period of 3 months, the market recovered and attained the yearly high value of 82 in February 2017 and March 2017.

32nd Costs, operational performance and yarn quality: Inter-mill study of key factors (October-December 2016)

This study is 32nd in the series on inter-mill study on 'Costs, Operational Performance and Yarn Quality'. In this study, 106 mills had participated. The following are the main findings of the study.

A comparison has been made with respect to 8 costs and operational parameters against the last study (31st study). Based on the deviations in the average values, relative changes in the individual mill's performance have been identified with respect to the common mills which had participated in both the studies (31st and 32nd).

In the 4th quarter of 2016, mills on the whole had registered about 20% drop in the contribution when compared to the 2nd quarter of 2015. During the 4th quarter of 2016, the yarn sale value did not register any significant change inspite of

Comparison with last study (April-June 2015)



6% hike in the yarn selling price. The raw material cost, on the other hand, had witnessed an increase of 11% in terms of Rs per spindle per year and 18% increase with respect to Rs per kg of yarn. When compared to 2nd quarter of 2015, salaries and wages cost had increased by 6% in 4th quarter of 2016 whereas the other input cost viz., power cost had witnessed a reduction of 14% among the common mills.

Between 2013 and 2014, the mills witnessed a significant increase in both yarn sale value (YSV) and RMC but with a drop in the contribution (by Rs 840 per spindle per year). Between 2014 and 2015, the mills, however, registered a substantial drop in both the YSV and RMC but with no change in the contribution. However, between 2015 and 2016, the overall drop in contribution (by 1000 per spindle per year) has been mainly because of the increase in raw material cost (by Rs 1500 per spindle per year) to a great extent (Figure 2). The above clearly indicates that the commercial performance is becoming more volatile.

Close to one-fourth of the mills registered an increase in the contribution (by Rs 1430 per spindle per year) with the increase ranging from Rs 60 to Rs 3830 between mills (Figure 3). The increase in the contribution in the above mills was due to an increase in sales turnover (by Rs 3190 per spindle per year) and reduction in power cost (by Rs 990 per spindle per year) which offsets the increase in raw material cost (Rs 2660) and salaries and wages cost (by Rs 90 per spindle per year). The remaining mills recorded a drop of Rs 1930 per spindle per year in the contribution with the drop ranging from Rs 220 to Rs 6520 between mills. In these mills, yarn sale value had registered a drop of Rs 1040 with an increase in

the raw material cost by Rs 1050 per spindle per year.

Out of 19 counts that are considered for analysis, common in both the 31st and 32nd studies, the yarn selling price had registered an overall increase of 6.4% among 17 counts, except in 60s C-Comp. and 30s CH counts (Table 1). On the other hand, RMC had witnessed a huge increase of 8.3% among 18 counts, except in 30s CH in which the RMC had registered about 10% drop in 2016. Since the increase in YSP did not follow the proportionate increase in RMC, the NOV on the whole had registered an overall drop of 14.15%, except in 100s C, 50s C-Comp. and 100s C-Comp. counts. Between counts, the NOV drop varied from 1.3% to 25.2%.

Comparison of snarling tendency of carded P/C blended yarns in ring, compact ring and open end spinning systems

The twisted shape of the fibres forming a yarn brings to the fore two of their main physio-mechanical properties: torsional rigidity and torsional buckling. Higher the torsional rigidity, stronger is the torsional buckling effect, also known as yarn twist liveliness. It is the tendency of a newly spun yarn to untwist spontaneously, a detrimental yarn characteristic that is responsible for the snarliness that occurs in the yarns and the spirality that appears in the knitted fabrics. Yarn twist liveliness is affected by the twist factor, yarn fineness and retractive forces, which, in turn, are determined by the torsional and balancing stresses in the fibre and the torque that is generated during yarn twisting.

During a product development for an Export company with P/C blends of different blend ratio, yarns produced with regular ring spun, compact ring spun and rotor spun ware tested for snarling behavior. The process details and the test results are given below as a case study to illustrate the above mentioned quality changes.

Polyester fibres blended with MCU 5 Cotton at 60/40 and 40/ 60 blend ratios were processed in ring, compact ring and OE spinning systems .The major fibre quality attributes of dyed polyester fibre is given in Table 1.

The major cotton quality attributes used for the above blending is given in table 2.

24s P/C carded yarns were produced at SITRA's pilot mill with 3 different spinning systems (Ring spun, compact ring spun and rotor). Different TM levels ware maintained for different systems in order to achieve almost the same yarn diameter. Yarn diameter was measured by the image analyzer technique. The yarn diameter of the P/C blended ring, compact and OE yarn samples with corresponding TM levels are given in Table 3. It may be seen from table 3 that almost similar diameter is observed in all 3 systems.

Snarling index testing

Snarling tendency of yarns can be checked with the help of a SITRA's snarling index tester Figure 1. It consists of a rigid wooden board on which 10 equi-distant horizontal lines are engraved as shown in line diagram. On the top of the board there are 6 guides and at the bottom there are 5 small hooks. The yarn is clamped between the guides after

passing around the hooks so as to form triangular loops.

The yarn is then released from the lower hooks and allowed to snarl freely after hanging a standard weight to each loop. The snarl index is read off against the line upto which the yarn has snarled. For normal yarns, the snarl index ranges from 4.0 to 5.5. For well conditioned yarns the snarl index is usually below 3.0.

The snarling index of the P/C blended ring, compact and OE yarn samples are given in Table 4.

Observations

Ø The Snarling Index of the yarn produced by rotor spinning was 15% lower when compared with compact yarns for both 60/40 blends and 40/60 blends.

Ø The snarling index of yarn produced by ring spinning when compared with rotor yarns was higher by around 24% for both the blends.

The results indicate that rotor yarns, with their wrapper fibre structure exhibit lower level of yarn twist liveliness (low snarling index) when compared to spiral twisted structures.

PAPER REVIEW

Compact Roving for Improved Quality of Ring Spun yarnKumarasamay Subbiah, Bhaarathi Dhurai, Venkatraman Subramaniam. Fibres& Textiles in Eastern Europe 2017; 25, 1(121), pp. 24-31

Compact yarn covers a major share in the Indian spinning industry. In the ring frame compact system, spinning triangle is small and almost all fibres are accommodated inside the yarn structure. Since the roving frame is a crucial process which decides the final quality of yarn, the same compacting system can also be adopted on the roving frame. Presently, coarser cotton yarns are produced on the roving frame with high twist for technical textile opplications. Moreover, there is a possibility of reducing the twist in the roving frame as a result of compactness (better cohesiveness) which gives more parallelization in the structure. The roving compactness provides an opportunity for reduced end breaks in roving frame and as well on the ring frame. This paper explores the possibilities of providing a compact system on the speed frame where the authors discuss about the two special tests, namely minimum twist of cohesion and roving cohesion strength in order to conclude that compactness had been formed in roving and also analyses about the packing density of yarn which inf luences the bulkiness, warmth, feel, moisture and dyeing characteristics.

Four types of yarn samples, a) Ring compact yarn (compacting in the ring frame), b) Roving compact yarn (compacting on the simplex machine), c) Double compact yarn (compacting both in the ring frame and on the simplex machine), d) Conventional yarn (without compacting either in the ring frame or on the simplex machine) were prepared and the quality parameters compared.

Results of compact roving are reported to be better than conventional roving in all the properties compared at a 1% level of significance. The U% of conventional roving was 4.58% and compact roving was 3.98 % being a significant difference in the value, attributed to the better alignment of all fibres towards the axis of the yarn by pneumatic suction. Loose fibres are held back inside due to the rolling action of the roving upon the inclined slot in the profile tube. Compact roving of 393.66 tex shows a cohesion strength value of 1.4 cN/tex, while for conventional roving it is 1.06 cN/tex, which shows an increase of 25% in cohesion. In the case of

compact roving, cohesion is obtained due to the parallelization of fibres and a higher number of fibres in the cross section, improving the roving strength. TM can be reduced in roving to get the same strength by using compact roving. A high drafting force is required to draft the high strength roving produced by high twist. But in the case of compact roving, the effect of the helical nature of the fibres is reduced, and thus a lesser drafting force is required. Hence the irregularity produced in high twist roving is reduced when compact roving is used. Higher packing density is an indication of compactness. The result shows, in compact roving that there is a decrease in diameter to the extent of 8.2% shows a significant difference in the packing densities of compact and conventional roving.

Results of yarn analysis indicates that compact roving yarn had improved uniformity, closer to that of ring compact yarn. The double compact, introduced both at the roving stage and ring frame stage, has improved yarn evenness, reduced imperfections and increased strength and elongation when compared to yarns with compaction only in the roving frame or in ring frame. Roving compact yarns ha d better evenness when compared to conventional yarns. Double compact yarns are still better in evenness when compared with conventional and other single compact yarns. The compact roving yarn had reduced imperfections and hairiness is reduced in compact roving due to better fibre alignment in roving formation. Increase in RKm and elongation was observed in roving compact yarn.

The authors conclude that compact yarns produced from compact roving show outstanding performance and compaction of roving represents a promising technology for future spun yarn production and could facilitate increase in profits. The advantages claimed include less f ly liberation in simplex department, more evenness, less imperfections and hairiness, high strength and elongation when compared to conventional yarns. Also claimed is a significant reduction in the yarn friction coefficient value, an increase in abrasion resistance, and higher f lexural rigidity values. The author also has a patent (No: 3050/che/2015: published on 01/04/2016) for this technology.
