Description

Deep color processing method of polyester fiber by bath treatment

The present invention relates to a deep color processing method of a polyester-based fiber characterized in that the polyester-based composite material is treated with a low refractive index resin using a bath treatment apparatus. After alkali dyeing as a disperse dye, the low-refractive index compound by the bath treatment device is treated with deep color aqueous solution evenly inside and outside the fiber and heat-set to form a film on the surface of the fiber to increase deep color effect and sharpness. It relates to a deep color processing method of the polyester-based composite material to improve the dye fastness.

In general, various researches and developments are being carried out to take advantage of polyester fibers and to improve their disadvantages to impart new functions. Polyester fibers have a smooth surface and high refractive index, and are particularly dyed with low molecular absorption coefficient dyes. As a result, the specular reflection of light is strong at the fiber surface, so that the stained color appears thin.

Conventionally known methods may be classified into a plasma method, a non-stretched effect yarn using a composite combustor, and a method using a low refractive index. However, the present inventors use a low refractive index resin to heat-set polyvinyl alcohol after heat treatment in a bath. The deep color processing of the ester composite material has been completed.

Hereinafter, the present invention will be described in detail.

Alkaline dyeing of the fabric of the polyester-based composite material in the present invention after treatment with 98-% acetic acid 0.1-1.0 g / l to adjust the pH to 7/0 or less, washing with water, drainage, An aqueous solution of 4.0-10.0% OWF mixed with a low refractive fluorine-based and silicon-based compound at a temperature of 40-60 ° C. for 1 hour in a bath at 40-60 ° C. for 1 hour, followed by dehydration to prevent antistatic agent 5.0-10.0 g. After immersion in a / l aqueous solution, the pick-up with a continuous dyeing mangle to 40-60%, dried for 1 minute at 100-130 ℃ using a tenter and heat-set at 170-180 ℃ for 30 seconds.

In addition, the amount of the low refractive fluorine-based or silicon-based compound resin to be used can also be easily set through repeated transfer experiments depending on the type, density, and structure of the yarn.

In order to maintain the deep color and flexibility of the fabric, it is possible to perform deep color processing with excellent dye fastness and prevent migration of disperse dyes only by heat treatment that the thickness of the film can be stably maintained rather than excessive high heat treatment.

Hereinafter, the present invention will be described in detail with reference to Examples.

Example 1

After weaving, scouring and weaving polyester filament yarns, the fabric is conventionally used for pretreatment, weight loss, and alkali dyeing, and then the pH is adjusted to 7.0 or less with an aqueous solution of 0.2 cc of 98% acetic acid dissolved in 1 liter of hard water. After adjusting, washing with water in an overflow bath treatment system, draining and supplying water, and then 4/0% OWF mixed with a low refractive fluorine compound at a temperature of 40 ° C for 1 hour in a bath at 40 ° C for about 1 hour. After picking up to 60% with a continuous dyeing mangle and dried for 1 minute at 130 ℃ using a tenter and heat-fixed at 180 ℃ for 30 seconds.

After the deep color processing, the color deviation * L value of left, middle, right, front and back was changed only between 9.5-10.0 using CCM. It was found to be flexible enough that no processing was used.

Example 2

After pretreatment, weight loss, and alkali dyeing of the polyester-based isomido composite material in a conventional manner, an acetic acid solution in which 0.2cc of 98% acetic acid was dissolved in 1 liter of hard water was adjusted to pH 6.0, followed by an overflow bath treatment apparatus. In an aqueous solution of 10.0 g of antistatic agent dissolved in 1 liter of hard water. After immersion, the pickup was 60% with a continuous dyeing mangle, dried at 130 ° C. for 1 minute using a tenter, and heat-set at 180 ° C. for 30 seconds to form a film.

As a result of measuring the color deviation * L value of the stained dye using CCM, the dye having a deep color effect with only a change of 9.0-10.0 and dyeing fastness was obtained.

Therefore, the polyester product according to the present invention not only has an excellent deep color effect, but also a deep color product of a polyester-based composite material by bath treatment of a product having excellent color fastness without the color deviation of left, middle, right, before and after. To get it.
