WAX DISC GENERAL INFORMATION AND PRODUCT DATA
General Information
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
Penetration
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.
Melting Point
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
Introduction
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.

Character
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.
Manual Winding
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.
Knitting characteristics
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.
Packaging
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.
