A new solution is proposed to decompose a curve into arcs and straight line segments in O(n log n) time. It is a combined solution based on arc detection [1] and dominant point detection [2] to strengthen the quality of the segmentation results. Experimental results show the fastness of the proposed method.

This paper introduced the study on preparation and properties of resin dye-fixatives on cotton fabrics in detail, and analysize the relations between their different structures, molecular weight and their fastness properties, from which some disciplines were obtained. Lastly, some suggestions on resolving the shortcomings of resin dye-fixatives on cotton fabrics were given according to the litu...

In this study an attempt was made to investigate bio pretreatment and chemical process observe the effects in terms of absorbency, bursting strength, wash rubbing fastness, water, energy consumption. Four samples (S1, S2, S3 S4) were prepared by different processes then dyed with two reactive dyes. When compared chemically fabrics, biopretreated fabrics demonstrated improved abrasion resistance...

In the present study, five naphthalene-based azo dyes were obtained using classical azo coupling reactions. The structure of the dyes was characterized and confirmed by the UV-vis, FT-IR, 1H NMR and 13C NMR analyses. The solvatochromic behavior of the dyes was studied in a set of 10 solvents with different polarity and considerable results were obtained. The dyes were applied as disperse dyes t...
