WAX DISC GENERAL INFORMATION AND PRODUCT DATA
Wax Disc Types
The information contained herewith is to the best of our knowledge correct and based on our many years experience. It is as the title suggests General Information given as a guide, but does not constitute a specification which is readily available. We are always pleased to offer advice or recommendations on request.
The waxes depicted here are our most popular types and refer to seven different ranges.
Each range has waxes of a similar formulation with approximately the same melting characteristics but a wide variation in hardness or softness consistency within the range, referred to as a Penetration value. This is given as a number and the lower number, the harder the wax.
By this system you are able to choose a suitable wax from a range, and after trying it, indicate an alternative from the range if necessary, in order to give a higher or lower wax pickup on the yarn.

Explanation of Testing Procedures
The depth in 1/10th/mms to which a special needle will penetrate a wax at 25c for 5 seconds when the needle is weighted to 100 grammes. The lower the stated number, the harder the wax.
In the laboratory we use many ways to test the melting point of waxes and each method produces a different result. The drop melting point stated in the information is one method we use. It is a quick method with good reproduction.
Lubricone range of wax discs
Lubricone Wax Discs manufactured solely by Gibson Parafin Ltd. represent many years of research and development aimed at producing a range of universal waxes to suit all yarns produced on all commercially made rotor spinning and winding equipment.
The Lubricone Range of specially modified waxes have been formulated to run efficiently under varying mill temperature and humidity conditions. Many modern auto winding machines suffer from local high temperature hot spots, particularly around the waxing unit. This can substantially effect the waxing of yarns if standard low melting point paraffin waxes are used.
Lubricone wax discs will not be affected by these higher temperature due to their inherent heat stability and higher melting points leading to greater stability of the wax disc i.e. the wax will not deform or soften over a broad temperature range. Wax disc deformities can lead to situations of inconsistent waxing whilst softening of the disc commonly leads to substantial overwaxing, which can cause the knitter as many problems as un-waxed yarns.
Lubricone wax discs promote extremely low coefficients of friction levels on most yarns with a low optimum uptake of wax being applied to yarns. For instance an auto-wound Singles Cotton of, say 1/24's, which will commonly show an unwaxed friction level of 0.22- 0.23 (measured on a modified Shirley Friction Recorder) can be waxed successfully with lubricone 110 and the co-efficent of friction be reduced to 0.13-0.14 by using as little as 0.2-0.3 %(o.w.f) of actual wax.
Many yarn processors still prefer to use manual types of winding equipment for back winding after dyeing. As a consequence of lower winding speeds, these machines tend to be more gentle on finished yarns, which is most important on for example fine count worsted yarns having a high wool content. This type of waxing is almost always of spinning disc mode where wax is applied manually (under gravity).
The range of lubricones from 130 to 250 have proved eminently suitable for this type of winding. In particular because of their clean running characteristics they are ideally suited for machines conditioning lick rollers are fitted. When soft unmodified waxes are used in such situations the machines can become congested with a combination of loose colored fibre and moisture collecting around the waxing unit and adhering to soft wax deposits. Lubricone waxes will avoid these problems yet still provide the low pickup and excellent friction characteristics as yarn that is wound automatically.
Lubricone wax dimensions
All wax discs are manufactured to the correct specifications as indicated by the machinery manufacturers. These specifications are detailed on a separate technical information guide, available on request which provides helpful references relating to wax sizes for particular machine types.
Many waxes are supplied colored tinted to for ease of identification. These colors which are employed at very low concentrations are fugitive and will in no way affect the yarns to which they are applied. All waxes can be supplied untinted on request, on a special order basis.
Please Note: Due to the very low concentrations of colour used in our manufacturing process the depth of shade may vary from batch to batch and supplies held in stock for long periods, may suffer from colour fade if exposed to heat or light for long periods. Colour fade if exposed to heat or light for long periods. Colour loss does not affect the efficiency of the wax discs in any way whatsoever.
Yarns that have been waxed with lubricone will exhibit excellent knittability. This literally means satisfactory fabric production without bursting of stitches, barreness or dimensional variation. It ıs also important that the knitting machines should not suffer from excessive wax deposits on guides,eyed and latches.
The earlier comments on low additions of lubricone are a particularly important factor in this area. Throughout Europe and possibly worldwide, it has become standard to judge coefficients of yarn friction by the use of Shirley modified friction apparatus. The effect of our waxes on yarns is being constantly monitored by this precise method by our customers and our own laboratory where we have installed our own Shirley apparatus.
Our modern well-equipped laboratories are constantly evaluating yarns and by utilizing friction recorders, extraction techniques and a single head multi-speed modern winder with both waxing and lick roller attachments can specify the exact wax type, the optimum amount of wax to be applied and the final coefficient of friction level necessary to suit customer requirements.
Lubricones are sold by weight and are packed in strong board cartons containing 10 kilos nett. For export purposes these are then further packed into an outer bulk carton holding 50 boxes in total 500 kilos NETT. These are then banded and palletized ready for shipment to the customer. Each standard 500 kilo(nett) pallet has dimensions of 117*100*117 cms, can be double stacked and has a gross weight of 546 kilos. Again the heat stability of these waxes ensures that they will not be significantly affected by high temperatures that may be encountered during transit of containers.
