USTERIZED® – the symbol of excellence in spinning
The USTER quality seal is a
hard-won but valuable business asset.
Market demand raises the bar for
yarn quality. Spinners recognize quality as a key success factor
and show ambitions to be the best in class. This article
describes the efforts some spinners take to hold the USTERIZED
certification for state-of-the-art quality management.

The USTERIZED® brand creates a global circle of
excellence for spinning mills, certifying the top-level
standards of quality management. Started in 1967 and expanded 10
years ago, the program requires spinners to meet stringent
technical specifications and implement efficient processes for
quality yarn production. Today, there are 68 USTERIZED®
certified spinning mills worldwide, 21 of which have held the
accreditation for 10 years or more. During 2016, nine more
spinning mills successfully passed the audit process and earned
the USTERIZED® certificate. Each candidate for membership has to
undergo a detailed and extensive examination of its quality
management systems. Comprehensive preparation is needed before
starting an USTERIZED® application. USTER provides support to
the spinning mills throughout, with training courses and visits
from specialists to support the mill, ahead of the USTERIZED®
To carry out the audit, experienced textile experts
assess the mills’ quality management systems. They will
recommend improvements in quality processes and consistency and
guide spinners towards ongoing analysis routines. Customer
feedback is that these audit procedures are a valuable service
in themselves, providing deep insights into quality management
and overall mill management needs.
Market demand raises the bar
Recent trends confirm a growing demand for higher quality and
at the same time consistent quality yarn from downstream users
in the textile chain. The USTERIZED® quality seal supports this
by assuring that certified spinners are capable of meeting this
requirement on a continuous basis. The bar is being raised – and
the criteria for USTERIZED® membership are progressing
A key aspect is the maintenance of consistent
environmental conditions in the spinning mill laboratory, to
ensure reliable measurement of quality values with USTER®
instruments for testing fiber and yarns.
USTERIZED® candidates must also focus on important
details such as a regular sampling plan and the use of yarn
quality profiles, as part of the quality management process. To
demonstrate suitable customer-oriented systems, spinners will
need to work with yarn quality profiles for selected articles,
as well as produce test reports using USTER® STATISTICS
percentile values for their standard yarns.
The USTERIZED® certificate must be renewed regularly. But,
unlike some other programs, this requires mills to do more than
simply prove again their original quality management standards.
At each subsequent audit, USTERIZED® spinners need to show
evidence of continuous improvements – which also includes
updated testing and monitoring technology.

are nine USTERIZED®
certified spinning mills in Pakistan.

The value that spinners place on their USTERIZED® recognition
is underlined by the efforts made by so many to pass the regular
audits – in some cases for 10 years and longer. The count of
long-term and new members at the end of 2016 showed that India
now has the largest number of USTERIZED® spinners. Other strong
USTERIZED® markets are in China, Turkey, Indonesia and Pakistan.
These spinners, and others worldwide, have earned the right for
their yarn to carry the USTERIZED® brand label – for instant
recognition of quality consistency in trading and deliveries to
