Reviewer: 1 Question: The paper is too long, distracted the focus. Response: Thank you for your question. We have deleted some needless words and highlighted in our manuscript. Reviewer: 2Question 1: What was the original starch material used for the experiments? It is not clear at all. Page 6, lines 3-4 and lines 39-40 must clearly state the starting sample (pulp from whole raw cassava roots? pulp from decorticated cassava roots? isolated cassava starch?). Specify also the processing of the starchy sample until it underwent the viscosity measurement (page 1 lines 1-2). Response: Thank you for your question. In our research, the original starch we used was commercial cassava starch, it is isolated cassava starch undoubtedly. In our paper, we mainly research the modified starch and its application in textile sizes. As to its initial processing, we did not pay to much attention, and the original cassava starch we bought was isolated in advance, so we did not process the commercial cassava starch until it underwent the viscosity measurement. Question 2: in Methods, there is a description gap between the production of powdered CLOC and its phosphatation. Please describe the intermediate handling of the CLOC powder before its mixing with sodium tripolyphosphate. Response: I am glad for you brought up the question. We had described it detailed as follow: 200 g of the CLOC (dry weight, the LCL is 370 AGU/CL) was dispersed in an aqueous sodium tripolyphosphate solution (the concentrations of the solution were 2.0, 4.0, 8.0, and 12.0% respectively, for the starches with the degrees of substitution of 0.08, 0.014, 0.024, and 0.038). Adjust the pH to 8 then stirred mechanically the dispersion for 30min at 40℃, then ?ltered, dried, pulverized and sieved for passing a 100 mesh-sieve. After the starch was further dried to moisture content 8%, heated to 130℃, and reacted at this temperature for 90 min. Finally, the product was washed with an ethanol-distilled water mixture (1:1
