Forming method of medium-deep dacron face fabric

Abstract

The invention discloses a forming method of medium-deep dacron face fabric, which comprises the specific steps that (100), high-temperature sublimation forming is conducted: the dyed dacron face fabric is taken out of a dye vat, and subjected to the high-temperature sublimation forming at greater than 130 DEG C by using a forming machine after scutching and squeezing; (200), reduction and soaping are conducted: the dacron face fabric after the high-temperature sublimation forming is subjected to the reduction and the soaping in the dye vat, and a dye attached on the surface of a fiber is washed clean; and (300), low-temperature forming is conducted: the clean dacron face fabric after the reduction and the soaping is subjected to the low-temperature forming at less than or equal to 130 DEG C by using the forming machine. With the adoption of the forming method of the medium-deep dacron face fabric, a specification of the face fabric meets a requirement; a cloth cover effect is level; and the color fastness is high.

Description

technical field [0001] The invention relates to the field of fabric processing, in particular to a method for shaping medium-dark polyester fabrics. Background technique [0002] Polyester is an important synthetic fiber. It is usually made of terephthalic acid and ethylene glycol, a polymer polyethylene terephthalate made through polycondensation reaction, and then spun into fibers. . It has high strength, good gloss, durability, strong chemical stability, mildew resistance and other properties that are incomparable to natural fibers, and occupies an important position in textile fibers. As a compound polyester fiber, polyester has a glass transition temperature of 80°C, that is, above 80°C, the crystallization of polyester fibers will flourish and change, and the fine structure of fibers will begin to change. The higher the temperature, the greater the change. The molecules in the polymer compound The faster the chain moves, the three states of the polymer compound appea...

AI Technical Summary

Problems solved by technology

However, if the temperature of the finished product exceeds 130°C after dyeing, the dye molecules will come out of the polyester fiber, resulting in a decrease in color fastness.

However, if the shape is not set at high temperature (above 130°C), the specifications and creases of the polyester fabric cannot meet the requirements.
