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.

Embodiment 1

[0023] The dyed polyester fabric is punched out from the dye vat, and then handed over to a setting machine for 190°C high-temperature sublimation for setting after the water is squeezed. Put the cloth after high-temperature setting into the vat for reduction soaping, and wash away the dye attached to the surface of the fiber. Soap the clean fabric and then hand it in for setting at a low temperature of 130°C.

[0024] High temperature sublimation: the disperse dyes will also sublimate the dyed polyester fabric under the action of high temperature. Under the action of high temperature, the polyester fiber will expand and the disperse dye molecules will overflow inside the fiber.

[0025] In the method for setting the shape of the dark polyester fabric in the present invention, the dyed polyester fabric is subjected to high-temperature sublimation, so that the dyed fiber molecular structure is re-arranged so as to reach a relatively stable state. Do a reduction soaping in the ...

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...
