How are the lubrication rings produced?
The incovenience caused by the yarns breakage during processing and its electrostatic charge in the past they constituted an obstacle to the reduction of processing times in contrast on increase in operating speed of the machinery. The use of paraffin, coming from oil industry, it was the first step, and was followed up over time, gradually based on direct experience, addition of other substances that optimize the result.
What gives the high quality of products?
Knowledge of the textile industry and a long experience are factors that have made it possible to modulate the characteristics of the product adapt it to the needs of each stage of processing of the yarns, obtaining differentiated products to take account of the type of fiber, temperatures, the type of machinery and time storage after waxing. In order to ensure the permanence of waxing for a long time, during the production phase of the rings of the
natural oils contained in paraffi ns are removed and replaces with synthetic oils.
What factors are agreed that the waxing are best suitable to specific yarns?
The type of textile fi ber that composes the yarn its perhaps the most discriminating element for choice ring lubricant. For example, of plant fiber such as cotton, viscose and silk, etc. Simply a modest release of lubricant to ensure the right speed to the yarn; instead for the wools, fine wools, syntheticand artificial fibers, its request a more significant lubrication.
How long a yarn remain waxed?
With the correct use of appropriate ring the timing of paraffi n yarn storage without alterations are extend to at least 12 months purposes to a maximum of 18. The final quality is also conditioned by the method of storage: they should be maintained at temperatures not lower than 20° and not higher than 25°, with appropriate percentages of moistures.
How’s the waxing reacts in the vaporization phase?
The yarn already lubricated may also undergo this process, which involves average temperatures between 50° and 70°, with very high humidity percentages.
All the rings are soluble in hot water (they melt) but, where it is required at the end of processing the total elimination of all of its components, it must foresee and adopt emulsifiable rings.
What are the consequences of a poorly waxed yarn?
A bad lubrication quality can often lead to yarn breakage or even to soiling of the machinery, drawbacks which affect the quality of the yarn and its processing times. For example, in processing machines with knitting, the breakage of the yarns and a wrong amount of lubricant up negativity are important because the speed of these process, need of the business, is in costant increase. For all these reasons and need the use of quality products and consistent with business needs.
What’s the meaning of paraffin rings codes?
Lubricating rings are produced and marketed in the most vari0us sizes, in order to be used on machines of all kinds. Codes that identify them, represent the dimension in millimeters of the diameter of the hole (Øi), the thickness (S) and the outer diameter (Øe).
