Fabric changes

Two tests were conducted to determine the influence of the pesticidal chemicals on the fabric. On the dyed fabric samples, color change due to chemical exposure was recorded both visually and with an instrumental colorimeter. On undyed cotton and wool fabrics, change in strength was determined using a tensile tester. 

COLOR DIFFERENCE. As shown in Figure 3 and Table I, the color of the aged fabric changes tremendously over 4 days when heated at 150 °C. A regression analysis of the linear portion of the line from time t — 24 to 96 h (i.e., t 24 h) gives the relationship ... 

Thus, after the first 24 h when the discoloration rate is somewhat faster, the silk fabric changes color at a rate of about 0.29 color difference units (CDU) per hour. 

Processes may lead to fabric changes, dilation, microfissuring, fracturing, loss of cementation, and so on, with massive effects on coupled processes, and in highly non-linear ways.

It will be observed dial such a classification gives (sify the broadest guide to the types of media available. As will be discussed in later sections, the information in the table on the minimum size of particle retained by a particular medhim must be viewed with reservation. Retention of particulates depends on many process variables and lower minima than reported in the table can be realised in practical separations. Thus in woven fabrics, changes in particulate concentration can produce particle capture much below 10 pm.

Using PGMA as an anchoring interlayer a switchable polymer nanolayer on the surface of PET textile material has been synthesized. The PET fabric changed the surface properties after being treated with different solvents (Fig. 17.11). When the fabric was exposed to toluene, it became hydrophobic and water did not penetrate the material. Conversely, water penetrated throughout the textile materials, if they were exposed to MEK. The wettability changes were reversible.
