Tarpaulin & Shade Net | Why are there standard tolerance for Tarpaulin & Shade Nets?
Thank
you for choosing a high-quality textile product of the TAIMEI. Our products are
manufactured on state-of-the-art production machines according to very strict
quality specifications.
However, every production environment will have
its own tolerances set in place. Industrial textiles include Tarpaulin, Shade Net, Geomaterial, require a
degree of leeway due to their malleable nature. Different materials, shrinkage rates, and physical characteristics are different, so the tolerances are different. Once the
fabric is used in the actual environment, these small variations tend not to be
noticeable.
Tolerance limits are limits that include a specific proportion of the population at a given
confidence level. In the context of quality control, they are used
to make sure that production will not be outside specifications
During
the manufacturing process of fabrics, faults are inevitable. In our quality
control, all faults which are outside the norm are sorted out. Minor faults like
e. g. knobs, oil-spots, thread breakage, thick and thin places, slubs, jutting
threads which are no longer than 5 – 10 cm are marked and thus are no reason
for complaint.
Below are the guidelines and recommendations of the outdoor industrial fabric tolerances:

If the customer can not accept the tolerances, then, it should be discussed before the production. Therefore some special treatments could lower the tolerances, such as heat treatment, which will take some costs.
In
most cases, when we produce the goods, we will predict the divergence and
tolerances and control the size, so customers will get the exact size after
receiving the goods. But sometimes, the tolerance will be larger according to the
temperature and environmental changes.
Within the bounds of our quality assurance, we try
to fall below these tolerances and to deliver you a quality that is
considerably above the standard of the China textile industry. If, despite this, you determine a fault that is not within the above-mentioned tolerances
please inform us immediately by phone or in writing to enable us to analyze the
fault.
