The black coating prepared by the method of the invention not only has a matte black luster, but also has the advantages of corrosion resistance and high hardness.

The invention relates to a method for preparing polyester fibers with ultraviolet-resistant and anti-pilling composite function. The method comprises an esterification reaction procedure, a polymerization reaction procedure and a spinning procedure, wherein the esterification reaction procedure comprises a primary esterification reaction stage and a secondary esterification reaction stage, and aliphatic dicarboxylic acid or non-p-aryl dicarboxylic acid serving as a third monomer is introduced in the primary esterification reaction stage; flexible polyethylene glycol serving as a fourth monomer is introduced in the secondary esterification reaction stage; a hindered amine light stabilizer and a hindered phenol antioxidant which are respectively prepared by using acetic acid and ethylene glycol as solvents and hydroxy silicone oil are added after the esterification is completed; and after the pre-polymerization of the polymerization reaction procedure is completed and before final polymerization, an ultraviolet absorbent is added. Before the spinning procedure, polyester slices are pre-crystallized and dried. The polyester fibers obtained by the method have excellent ultraviolet-resistant and anti-pilling function; and after the polyester fibers are woven into knitted fabrics and woven fabrics, tests show the related technical indexes that: the ultraviolet transmission rate is less than or equal to 5.0 percent, and the anti-pilling performance is more than or equal to level 4.

The invention relates to a production technology of fabric, and discloses a production technology of Roman cloth. The production technology solves the problems that the Roman cloth weaved by yarn twisted by spandex and chinlon is poor in heat resistance and can easily get yellow in high temperature weather in summer, and the quality of the Roman cloth is influenced. The production technology is characterized by comprising yarn pretreatment, steam shaping, weaving for cloth, dyeing, aftertreatment, check and package, in the yarn pretreatment process, the yarn is soaked into alkali liquor for aperiod and is then taken out to be thoroughly cleaned, brucite powder is added into a soaking pool, the cleaned yarn is added into the soaking pool, is heated to 80-120 DEG C, is subjected to heat preservation for 60-90 minutes and is slowly cooled to be washed with cold water, and the heat resistance of the Roman cloth is improved, so that the Roman cloth is not likely to get yellow in high temperature weather in summer and is better in quality.

The invention relates to a matt polycarbonate styrene resin alloy.
