Abstract
The waterproof and oil-repellent finishing of the dyed single-sided plain cotton fabric was carried out by two-dip and two-pad process. The influences of baking temperature (°C), baking time (min), concentration of finishing solution (g/L) and percentage of liquid on waterproof effect of fabric were analyzed; the influences of the contact angle and the baking temperature (°C), the baking time (min) and the concentration of the finishing agent (g/L) on the oil repellency of the fabric were investigated. The results showed that the best water-repellent finishing technology for cotton fabric was the concentration of finishing agent 30 g/L, the baking temperature 110°C, the baking time 1.5 min and the liquid-uptake 70%. The best oil-repellent finishing process for cotton fabric is 35 g/L for finishing agent, 150°C for baking temperature, and 1.5 min for baking time and pick up rate of 80%. After cotton fabric is treated with water-repellent and oil-repellent agent, the water-repellent contact angle of the fabric can reach 128° and the oil-repellent grade 6. The best finishing effect is obtained at this time. After the finishing agent acts on the surface of the fibre, the surface properties of the fibre can be changed, and the surface of the fibre can be changed from hydrophilicity to hydrophobicity. The finishing agent has good film-forming property, which makes the surface of cotton fibre smooth and has good waterproof and oil-repellent performance.

Summary
Fabric can stay recycled to type clothing for people and numerous additional things. People often wear cotton clothes, especially in hot weather. Today’s cotton stays the greatest recycled textile fibre in the establishment. The whole fibres used in clothing and domestic things ensure a marketplace share of 56% in the United States. The initial indication of cotton use came since India, and the period given to fabrics was 3000BC [1]. Cotton fabrics of considerable age must be established in different countries. Cotton planting began to spread from India to Egypt, China, and the South Pacific. Long fibres are suitable because they are easy to spin and produce strong, smooth yarns [3]
