The effect of thermosetting resins on the light fastness and shade change on reactive dyes was studied, Results of the study show that: 1. There is no correlation between the change of shade and change of light fastness as a result of resin treatment. 2. The effects of two graups of resin, dimethylo1 N triazone and urea-formaldehyde, on change of shade varied some what, they occurred some color difference. 3. The effect of the resin on light fading depends on the characteristics of resin used and molecular structure of dyes. generally, dimcthylol-N-triazone decreased the light fastness but urea formaldehyde some what increased. 4. The physical states of dyes in the fiber have a considerable affects on the light fastness. 5. The dyes have an initial rapid first order fading, and after, fade very slowly and at a more or less constant rate, resembling in fact more ordinary dyes.

The physical properties of woven fabrics such as yarn crimp, tensile strength, elongation, tear strength, bursting strength, air permeability, cover factor, tightness, thickness and weight per unit area were investigated on the seventeen different fabrics of plain, twill, sateen and basket weave. The samples were prepared from the fabrics woven with one kind of cotton yarn under the same tension in weaving process. Crompton & Knowles S-6 Loon was used in weaving. As a result of analyzing the experimental data by the related theory of fabric geometry, it is realized that the number of yarn intersections per inch is one of the most important factors which affect many physical properties of fabrics. The results are as follows: 1. The number of yarn intersections Per inch has the Positive retationship with the tensile strength as well as the elongation and the negative relationship with the air permeability. 2. The higher value of weave factor and the less difference in sum of neighboring yarns of upper and lower part of a yarn parallel to the direction of tear, the more increases the tear strength. 3. No significant difference of physica1 properties were observed on the same harness sateen weaves having different counter number. 4. The maximum number of picks per inch weavable in a fabric is limited by the number of ends per inch in the same weave and if tile ends per inch is constant in different weaves, the maximum number of picks per inch increases as the weave factor increases.

For the purpose of the selection of suitable base fabric of Army Raincoat, co-relation of surface condition and adhesion on several kind of domestic cotton cloth were broadly investigated, Seven ditterent kinds of cotton cloth were processed with mill scale and then went into topping operation with natural rubber(RSS#3) and synthetic rubber (SBR#1502). Comparison of adhesion was made after each step of wet processing and of the raising operation. The conclusion was made as follows: 1. Non calendered fabric shows much better adhesion than calendered. 2. Raising operation has not shown good advantage in adhesion. 3. A base fabric textured with finer yarn and higher density have shown better adhesion.
