Problems solved by technology

[0002] Polyester (polyester) fibers are widely used in outdoor decorative fabrics (furniture, awnings, etc.) due to their high modulus, high strength, and aging resistance. Or use high-sun disperse dyes for dyeing, but because the color fastness of masterbatch soluble silk spinning products is excellent, but the minimum order quantity is generally 5-20 tons per batch, it is not suitable for the development of small batches of multi-variety products. However, due to the high price of high-sun disperse dyeing dyes, the cost remains high in the dark product series, but it is suitable for the development requirements of small batches and multiple varieties of products.

Abstract

The invention provides a preparation method of outdoor polyester decorative fabric. The preparation method comprises the following steps: a) polyester (dacron) color masterbatch is subjected to fusingwith a conventional process for yarn spinning, and polyester yarn in light, medium and deep basic colors of each color scheme is prepared; b) a dyeing bobbin is wound with the polyester yarn layer bylayer, and cheese is formed; c) the cheese in similar basic colors is placed into a dye vat, and dye liquor is prepared in the dye vat in the bath ratio being 1:8; the dye liquor is heated to 48 DEGC and kept at the temperature for at least 10 min; then the dye liquor is heated to 128 DEG C and kept at the temperature for at least 30 min; the dye liquor is cooled to 75 DEG C, kept at the temperature for at least 5 min and drained; d) the dyed cheese is subjected to conventional functional finishing; e) the cheese passes through a 135-DEG C oven channel continuously at the rate of 35 m / min and then passes through a 155-DEG C setting high-temperature channel continuously at the same rate; f) a finished outdoor decorative fabric product is prepared from the processed polyester yarn with theconventional weaving process.
