Hazards in Spinning Industry and How to Prevent Them May 29, 2023 Himanshu Fogla Spinning cans ♦ ♦ ♦ Every tex?le mill looks to op?mise the qual? of the yarns it produces. However, if the spinning cans being used on the mill floor are defec?ve, that can throw a spanner in the works. Apart from damaging original sliver parameters and final yarn qual?, can defects may – over ?me – a?ect the func?onal? of spinning machinery as well.  Before elabora?ng on the knock-on e?ects that crop up when sub-standard or defec?ve sliver cans are used, it is important to have an idea about the common ?pes of can defects. From problems in the HDPE sheet welding and incorrectly fixed bo?om plates (which, in ?rn, causes can ?l?ng), to selec?on of the ‘wrong’ spring load, sub-standard caster wheels & more – there can be a myriad of problems in cans that are not up to the mark. We will here elaborate on the issues that can crop up as a result of using defec?ve spinning cans: So, How is the Performance of Spinning Machines A?ected by Problema?c Spinning Cans? Con?nuous usage of defec?ve cans (and sliver handling systems, in general) a?ect sliver qual? and spinning e?ciency in diverse ways. Let’s examine these poten?al problems in greater detail: Problems at the Carding Phase For op?mal performance and longev?, carding machines have to be used with spinning cans that are absolutely glitch-free. Several ?pes of problems can, however, crop up at this stage. For instance, if there is accidental can ?l?ng, both the silver coils AND their qual? are hampered – causing higher-than- acceptable volumes of sliver wastage (at the ?me of unwinding at the creel zone). The e?ciency of the carding machines is also likely to deteriorate, since

2. creel breakages are higher. There are loading problems and resultant produc?on stoppages. Not selec?ng the correct spring load in the spinning cans also leads to a host of problems – related to greater unevenness in the rela?vely lower coils of the sliver. Both the CVm% and U% of sliver goes up, a?ec?ng the final qual?. Using sliver cans with jammed / damaged caster wheels is also not recommended. Such casters inhibit the smooth transporta?on of the cans on mill floors. As a result, labour fa?gue levels go up, and delays happen. Problems During Breaker Draw Framing Once again, if the spring load of the cans is not appropriate, they can pose problems at the breaker draw frame. Since the U% increases significantly, the overall qual? of sliver automa?cally goes down. The Lap Forming Machine is used to receive the sliver from breaker draw framing cans, and prepare the laps for the next phase (combing). When the spring load of the cans is erra?c or unstable, there can be considerable rise in the weight of sliver in the creel zone (of the lap former) – as a result of which sliver stretching, a commonly encountered yarn imperfec?on, happens. In add?on to the sliver stretching, the risks of breakage can also go up exponen?ally in the creel zone. Since the number of pieciengs are more due to the defec?ve cans, the lap qual? gets adversely a?ected, labour load increases, and the consequent loss of produc?on ?me / qual? is likely to be significant. Problems at the Combing Phase At this point, it is important to understand the di?erence between carded sliver and combed sliver. The la?er is a lot heavier / bulkier than the former – and as such, the spring load of the comber cans also needs to be higher. Now, if this load is not set up correctly, the fibre-to-fibre cohesion is not maintained at the requisite levels, risks of sliver breakages and damages are more at the finisher draw frame creel zone. The higher the volume of these sliver breakages, the greater is the number of pieciengs, labour loads, and overall faults / inconsistencies in the sliver. When this happens, the comber machine itself starts to lose e?ciency – and its performance starts to gradually go down.  Lack of stabil? is a common problem in defec?ve spinning cans. This, in ?rn, can easily cause the cans to get ?lted – thereby making the can movements inside the coiler system wobbly and non-uniform. In add?on to the U% and CV% of sliver going up as a result of non-uniform can movements, there are more entanglements in the sliver as well, along with associated coil damages. Problems During Finisher Draw Framing As already pointed out earlier, the fibre cohesion levels in combed sliver is rela?vely low. On top of that, if the can springs are defec?ve (i.e., the spring load is inaccurate), the sliver strength is a?ected – since the spring load is not enough to maintain the top-level sliver coil at the same level with the can top. As a direct result, sliver starts hanging with its own (unsupported) weight. Since the sliver separa?on is increased and the stretch percentage is higher, the qual? of the final yarn is compromised. The spring load of spinning cans has a direct impact on the U% and CVm% of sliver. When there are problems in this load, thin faults crop up, the CV% rises, and there are more breakages in the speed frame creel zone. This happens because the gap between the creel and the top coils of the sliver becomes higher.

3. Problems at the Roving Phase By now, it is pre?y much evident that spinning cans with incorrect spring loads can cause a lot of problems – both in terms of output qual? and mechanical performance. In add?on, if the storage ?me of sliver in the cans is higher than required, that also causes greater unevenness, and higher CV% (strength & count). The roving qual?, as a whole, goes down. When the spring load of cans is lower than the required level, problems come up in the winding phase as well. From CM cuts and CCM cuts, to CP cuts and CCP cuts – all the counts go up when the springs are old and / or do not have the ‘right’ load. When the spring load is correct, there is much greater assurance regarding sliver strength. How can Jumac Manufac?ring Help in Elimina?ng these Problems? As an industry-leader from the field of sliver handling, we bring a combina?on of world-class technical acumen and the most advanced tools & solu?ons, to rule out possibil?es of can defects (and resultant problems in mill performance). All products are designed at our state-of-the-art manufac?ring unit – and we provide detailed spring load sugges?ons, so that there are no uncertain?es. Spinning cans, trolleys, and all other accessories are manufac?red in-house, and in adherence to stringent qual? parameters. At Jumac, a systema?c and highly reliable method is followed for assembling the cans. As such, can ?lt risks are minimised (since the bo?om plates are securely fixed). The an?-sta?c HDPE sheets used in the can bodies eliminate risks of sta?c charges, while the nylon caster wheels (with SS frame) come with complete dust-free and flu?-free assurance. As a result, can movements are smoother and operators can work with them more easily. Many instances of yarn qual? mismatches and gradual deteriora?on in the performance of spinning machines can be a?ributed to con?nuous use of defec?ve spinning cans. It is always advisable to source these cans from a reliable & reputed sliver can manufac?rer – while having the cans inspected (for probable damages, wear & tear, etc.) is of paramount importance too. Malfunc?oning cans can result in the en?re sliver handling system ge?ing compromised – and in the increasingly compe??ve landscape of today, mills simply cannot a?ord that!
