Fabric, degradation

Figure 4. Strength of cotton print clothes thermally degraded by heating at 168°C for various times. The strength of fabrics degraded by hydrolyzing 16 hr in 40% sulfuric acid at room temperature and by high-voltage electron irradiation at doses of 50 and 100 Mrad are also indicated.

Substrates. The fabric substrates consisted of a standard 80 X 80 count (nominal) 3.5 oz/yd2 cotton print cloth, machine washed in a 0.1% solution of Triton X-100 this fabric exposed to 50-, 100-, or 150-Mrad doses of high energy electrons as described in Part I of this series (2) or this fabric degraded by hydrolysis in 5N HC1 at room temperature for 5.5 h. These degraded model fabrics were selected because their properties were sufficiently similar to those of archeological samples and because they could be prepared readily in large quantities. 

Figures 7-19 to 7-23 show the various fabric paths in continuous open-width bleaching equipment with steamer systems based on positive fabric guidence without plaited storage. The main features of this system are very much suitable for crease susceptible fabric, fair degree of whiteness, fabric with good absorbancy, less chances of fabric degradation and fair mote removal.

Fabric degradation and destruction of weak cementation bonds from disturbance... 

Color degradation can be broken down into three different processes fabric degradation, dye removal from fabric, and dye transfer in the wash process. Color protection can be achieved by attacking any one of those processes. Typically color protection is documented over multiple washes, due to the levels of ingredients used and the sensitivity of the eye to slight changes in color [31].
