Description

TECHNICAL FIELD [0001] The present invention relates to a synthetic fiber yarn having a phosphorescent property,

The present invention relates to a synthetic fiber yarn having a phosphorescent property and a manufacturing method thereof, and more particularly, to a method of manufacturing a synthetic fiber yarn having a phosphorescent property, A synthetic fiber yarn having a phosphorescent property capable of shortening the process by producing a synthetic fiber yarn by continuously injecting it into a melt spinning machine and capable of producing an economical synthetic fiber yarn excellent in luminous efficiency and functionality of a synthetic fiber yarn, And a manufacturing method thereof.

As the industry develops, various functional products are manufactured and sold and many products with phosphorescent functions such as watches, electronic devices, interiors, markings, fire protection devices, lighting, fashion products, And has been applied to various kinds of clothes and textile products.

Methods for imparting phosphorescence characteristics to various garments and textile products include a method of applying a phosphorescent pigment on the surface of garments and textile products, and a method of applying a phosphorescent pigment to a synthetic fiber by spraying.

However, the fiber produced by the above method has a disadvantage in that the phosphorescent pigment tends to be desorbed when worn or washed, has a low light emission level, and has a short emission time.

In addition, although a method of adding a phosphorescent pigment to a synthetic resin to express the phosphorescence property is used, there is a problem in that the luminance is low and the emission time is short, and since a lot of phosphorescent pigment must be used, The strength of the fiber yarn is lowered.

On the other hand, conventionally used phosphorescent pigments such as ZnSiCu-based phosphors have a problem of practical use because the luminescence time is not longer than about 5 minutes, and there is a problem that it is difficult to identify characters due to low luminous intensity, It has a disadvantage in that it is not good in weatherability and thus it is difficult to apply to clothing and textile products.

Generally, phosphorescent pigments have good luminescent properties because they have thick particles. When the particles become thick, they are not mixed well with resin chips and melt spinning, so that the surface is rough and passes through the nozzles. There is a lot of silence.

Therefore, it is difficult to produce a smooth phosphorescent yarn. Conventional methods include masterbatching or encapsulating a phosphorescent pigment, mixing about 70% of a polyester (PET) chip with about 30% of a phosphorescent masterbatch, drying the mixture, Methods for producing phosphorescent fibers are disclosed, and synthetic fibers are manufactured by a similar process to functional additive materials.

1, a phosphorescent material or a functional material (powder state) is reconstituted or encapsulated and mixed with a synthetic resin chip to be processed in a masterbatch form, and a synthetic resin chip 70 %, And the mixture is put into a melt-spinning machine to obtain a synthetic fiber yarn having a phosphorescent property and a function.

In addition, when the phosphorescent and various functional materials are heated many times during the processing, there is a problem that the functionality is remarkably decreased. Various functional materials mixed in the synthetic resin chip are mixed with the pure synthetic resin (RESIN) There is a problem in manufacturing a functional yarn of good quality because mixing is not performed.

Therefore, in the past, the cost to make masterbatch and the heat and deformation have been reduced by heating several times, and the strength and brightness have been lowered and the functionality has been significantly lowered. .

Most synthetic resin chips have to be dried. In particular, nylon and polyester resins must be dehumidified (0.003%). Accordingly, in the present invention, polyester chips are continuously supplied in a continuous dehumidifying dryer at 170 DEG C for 4 to 5 hours by dehydrating and drying (moisture content: 0.003 to 0.004%) and continuously supplied with a vacuum stirrer. In a vacuum stirrer, 8% by weight, antimicrobial agent 2%, other additives such as antistatic agents and aggregates, and vacuum-agitated at 190 ° C for 30 minutes to uniformly coat the surface of the polyester chip.
