Coatings and finishes in the textile industry

Many companies in the textile industry either have their own test laboratory to check the quality and characteristics of their raw materials and final products or have them regularly tested by research institutes. The Soxhlet extraction is a frequently used method to analyze certain fibers and additives, e.g. the avivage of a fiber.  The avivage is a fiber preparation to improve the lubricity and friction of the yarn to ensure a smooth production process. This treatment avoids high wear out effects on the productions machines, e.g. overheating of industrial sewing machines. The determination of fat/oil contents in the fibers can be carried out either with the classic Soxhlet extraction or with the fully automated SOXTHERM® of C. Gerhardt. The SOXTHERM® offers significant advantages, especially for laboratories with high sample volumes:

 - less time for analysis
 - can be operated without supvervision
 - can process up to 24 different samples simultaneously

Versatile possibilities of SOXTHERM® in the textile industry

With the corresponding SOXTHERM® application "coatings and finishes with textiles", which observes DIN 54278-1, coatings of fibers and textiles can be determined. This results in a wide range of applications for the device in the textile industry. C. Gerhardt successfully installed several units at customers both from the "woven" materials and the "nonwoven" materials sector.

An overview of the application possibilities of the SOXTHERM® gives the following overview of already analyzed samples:

Wool and HairSilks and other Protein FibersCotton
Regenerated Cellulose FibersBast and Rigid FibersPolyester Fibers
Acetate FibersTriacetate FibersPolyamide Fibers
Polyacryl FibersPolychlorid FibersAramid

 

A further method which is applicable in SOXTHERM® is the sample preparation for the determination of certain aromatic amines derived from azo colorants according to method EN 14362-1.

Another application in the textile industry is the ASTM D2257 "Standard Test Method for Extractable Matter in Textiles" which includes a wide range of operational areas for the SOXTHERM®.
