Recently, there is a growing demand for flame retardant functions in various markets such as interior safety materials for living, interior, protective clothing, curtains, sofas, bedclothes, industrial protective clothing and protective gloves.
There is polyphenylene sulfide (PPS) fiber as a fiber in which such a flame retardant material is required. The polyphenylene sulfide is a fiber of a flame retardant material and has inherent physical properties showing stability to heat. Therefore, the polyphenylene sulfide is excellent in flame retardancy, stable in smoke density, and capable of controlling toxic gas. In addition, polyphenylene sulfide fibers have excellent advantages in terms of continuous heat resistance, chemical resistance, low absorption characteristics, shape stability, and chemical resistance.
Polyphenylene sulfide fibers that are easy to dye for each application are needed to create a new market by expanding various applications beyond the limited use of existing polyphenylene sulfide fiber's excellent flame retardant function.
The dyeing of polyphenylene sulfide fibers and the improvement of light fastness are required to replace the existing interior materials and to replace other engineering fibers. In other words, although the flame retardancy and heat resistance of polyphenylene sulfide fibers have been well proven, it is necessary to secure verification and control technology of smoke density and toxic gas in order to apply interior materials for air railway trains, which are strictly flame retardant, .
On the other hand, in order to be used as an interior material or an interior field, the most important thing next to the flame retardancy characteristic is that it has a visual characteristic. In particular, light fastness to dyed products is also an important factor, as architectural interiors such as curtains and interior materials for vehicles such as automobiles are exposed to extreme environments (heat or ultraviolet rays due to sunlight) for a long time.
Therefore, the chlorination technique of polyphenylene sulfide fiber is an essential element technology to replace the existing general purpose fiber product and to enter the super fiber market which can dye the polyphenylene sulfide by maximizing the inherent physical properties.
In the case of polyphenylene sulfide fibers which are currently being produced for applications requiring durability, such as for interior automotive interiors or interior applications, the sheath is made of a sheath-core type composite using ordinary flame retardant PET resin Radiation fibers have been applied, but heat resistance and other physical properties are low, which may cause problems in the development of applications.

In order to solve the above problems, an object of the present invention is to improve dyeability and light fastness while maintaining the inherent properties of polyphenylene sulfide, such as flame retardancy, toxic gas control, persistent heat resistance, and chemical resistance.
It is still another object of the present invention to provide an optimal spinning technique capable of simultaneously satisfying both spinnability and dyeability of polyphenylene sulfide fibers.
In order to achieve the above object, the present invention provides a flame-resistant polyphenylene sulfide fiber comprising 1 to 10% by weight of a halogenated polyphenylene sulfide resin and 90 to 99% by weight of a non-halogenated polyphenylene sulfide resin .

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional view of a dosing machine used for mixed spinning of the flame-resistant polyphenylene sulfide fibers according to the present invention; Fig.
The
Generally, in order to obtain a fiber by spinning a salt-generating polyphenylene sulfide resin, only the use of a flame-retardant polyphenylene sulfide resin such as the above-described chemical formula 3 or 4 can be considered.
However, when the ratio of the portion having an acidic or basic functional group capable of ionic bonding with a cationic or anionic dye in the above Formula 3 or 4 and the portion not having an acidic or basic functional group is adjusted, that is, But it is not simple to control the polymerization process by percentage.
Instead of using the
In addition, when it is spun by only the above-mentioned flame-retardant polyphenylene sulfide resin (Chemical Formula 3 or 4), the radial influence (increase in pack pressure) can be given due to the acidic and basic functional structure of the fluorinated polyphenylene sulfide monomer in the resin, When the dosing machine is used, it is uniformly mixed with the non-reducing polyphenylene sulfide resin (20) at an optimum ratio, and does not have a large influence on the radial direction.
Further, the flame-resistant polyphenylene sulfide fiber spun using the dosing machine should have a fineness of 3.0 denier or less and a strength of 4.0 g / d or more. This is because aesthetic requirements are important for use as garment fibers, and therefore, it is necessary to have the characteristics of three filaments as much as possible.
In addition, the above-mentioned spunbaceous polyphenylene sulfide fibers can be used for a fiber aggregate, that is, a spun yarn, a fabric and a filament. In this case, the flame retardancy (LOI) shows a quality of 25% or more.
Hereinafter, embodiments of the method for producing polyphenylene sulfide fibers having excellent dyeability and light fastness according to the present invention will be described, but the present invention is not limited to the examples.
Example 1
1% by weight of a polyphenylene sulfide master batch resin containing 40% by weight of an acidic functional sulfonate (SO 3 - ) comonomer in the salt-free polyphenylene sulfide and 99% by weight of an unreinforced polyphenylene sulfide resin Prepare a fabric using a chlorinated polyphenylene sulfide fiber spun on a dosing machine and dye it using a disperse dye. The dyeing is carried out at 130 ° C for 60 minutes using a disperse dye.
Example 2
5% by weight of a polyphenylene sulfide master batch resin containing 40% by weight of a salt polyphenylene sulfide comonomer and 95% by weight of an unreinforced polyphenylene sulfide resin were used in the same manner as in Example 1, .
Example 3
Except that 10% by weight of a polyphenylene sulfide master batch resin containing 40% by weight of a salt polyphenylene sulfide comonomer and 90% by weight of an unreinforced polyphenylene sulfide resin were used in the same manner as in Example 1, .
Comparative Example One
Prepare the fabric using polyphenylene sulfide fiber spun with non-degradable polyphenylene sulfide resin and dye with disperse dye. The dyeing is carried out at 130 ° C for 60 minutes using a disperse dye, and the physical properties such as dyeing density and daylight fastness of the fabric are measured.
◎ Method of measuring concentration
The surface reflectance was measured at the maximum absorption wavelength of the dyed fabrics and the dyeing density of the dyed fabrics was compared by calculating the K / S of Kubelka-Munk equation.
◎ Daylight fastness
According to KS K ISO 105-B02, the degree of discoloration of the test specimen is measured by measuring the degree of discoloration of the specimen by illuminating the artificial light source and comparing with the standard gray color chart.
◎ LOI (Flame retardant)
ASTM D 2863 Determine the oxygen index (%) according to the combustion behavior of specimens with a length of 140 mm and a width of 52 mm, based on the oxygen index (LOI) measurement of textile fibers.
※ Radioactive defect △ Normal ○ Good ◎
In Comparative Example 1, it was found that the fiber was non-bleaching polyphenylene sulfide resin and had good radioactivity.
On the other hand, in Examples 1 to 3, a master batch resin containing 40% by weight of an acidic functional sulfonate (SO 3 - ) comonomer in the salt polyphenylene sulfide by using a dosing machine and an unconjugated polyphenylene sulfide The amount of the polyphenylene sulfide masterbatch resin influences the radioactivity depending on the content of the polybrene sulfide masterbatch resin. In the case of 1 wt%, 5 wt%, the radioactivity is good and 10 wt% is a moderate value .
The larger the value of K / S, the higher the degree of the saltiness. In the examples, the content of the master batch resin containing 40% of the acidic functional sulfonate (SO 3 - ) comonomer in the salt polyphenylene sulfide The higher the number, the better. However, the master batch resin containing 40% of the fluorine-containing polyphosphorus sulphide comonomer related to taurine may be deteriorated in radioactivity, so that the content between 1 and 10% is the optimum range to satisfy the radioactive and the taurine Able to know.
In Comparative Example 1, the fiber composed of the non-reducing polyphenylene sulfide resin has the lowest concentration of the fibers.
Finally, it can be seen that the flame retardancy (LOI) of the polyphenylene sulfide fibers is similar to that of the polyphenylene sulfide fibers in the range of 25 to 30% without distinguishing the characteristics of the examples and the comparative examples, irrespective of the presence or absence of the flame retardancy.
In conclusion, it can be seen that Example 2 is the most optimal condition for the radioactive and the salts in the Examples.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be clear to those who have knowledge of.
