Durable press finishing imparts characteristics to a fabric which are very desirable in todayVs market.
Crosslinking resins are used to impart this finish which helps to control shrinkage and gives fabrics crease
resistance, or permanent press characteristics. Most current methods for detecting the amount of res
on a fabric are very subjective and do not give the actual amount of resin present. The only method which does give the actual amount of resin present is the Kjeldahl test.
The drawbacks to this test are that it is very time consuming and requires trained personnel. Recently, it has been shown that Near Infrared
Reflectance Analysis is a quick, easyu and accurate method of determining the amount of resin on a fabric. Variables
that may be encountered using NIRA in a production environment were studied in order to determine how they
would influence the MIRA measurements.
The results show that a simple bias adjustment is all that is necessary in order to make a calibration previously
developed for reading fixed resin accurate for all variables examined in this thesis. MIRA is a quick and
easy method to determine resin content. Labor costs and off quality may be reduced in this technology is used in production environments.
