Title: Color masterbatch composition for dark textiles or engineering plastics and article produced therefrom

Description:
TECHNICAL FIELD OF THE INVENTION 
     The present invention relates to a color masterbatch composition, and more particularly to a color masterbatch composition for textiles or engineering plastics and an article produced therefrom. 
     DESCRIPTION OF THE PRIOR ART 
     Dark textiles are commonly used in clothing, curtains and sofas, and dark engineering plastics are widely used in electrical appliances and automotive components; they have a good shading and dirt avoidance. Generally, the pre-spinning coloring of dark textiles or engineering plastics is obtained by adding carbon black which is easily obtained as a pigment to the raw materials, but the problems of easily absorbing infrared light and causing its products to be rapidly increased in temperature are thus generated. 
     Taiwan patent TW 1509038 discloses an infrared low temperature-rise pigment composition, capable of reducing the temperature rise caused by the absorption of infrared light by selecting specific pigments to combine. However, it is noted that the plastic films formed by most of the pigment compositions disclosed in the above patents and thermoplastic polyesters cannot maintain the original colors of the pigment compositions after the necessary processing of the textiles or engineering plastics (e.g. heating at 285-300° C.); they must be further dyed after the products are formed, and the dark textiles (post-spinning coloring) or engineering plastics can then be produced such that the processing complexity and wastewater pollution are increased. 
     SUMMARY OF THE INVENTION 
     The first object of the disclosure is to provide a color masterbatch composition, capable of overcoming the above shortcomings. 
     The color masterbatch composition of the disclosure includes thermoplastic polyester, a yellow colorant component, a red colorant component, and a blue colorant component. The yellow colorant component is selected from Pigment Yellow 147, Pigment Yellow 181, Pigment Yellow 183, Dye Brown 53, or a combination thereof. The red colorant component is selected from Pigment Red 122, Pigment Red 144, Pigment Red 202, Pigment Red 214, or a combination thereof. The blue colorant component is selected from Pigment Blue 60, Dye Blue 67, or a combination thereof, the above colorants is expressed in color index common names. 
     The second object of the disclosure is to provide a colloidal particle, obtained by developing the color masterbatch composition in a base material mainly composed of thermoplastic polyester. 
     The third object of the disclosure is to provide a fiber, obtained by drawing the above colloidal particle. 
     The fourth object of the disclosure is to provide a prepreg, obtained by molding the above colloidal particle.

     Implementation Examples C1 to C32, D1 to D32] Color Masterbatch Composition 
     The steps of implementation examples C1 to C32 and D1 to D32 are similar to those of implementation examples A1 to A32 and B1 to B32, respectively. The difference is that PBT replaces PET to prepare the masterbatch compositions of implementation examples C1-C32 and D1-D32, respectively. 
     Comparative Examples 
     [Comparative Examples CB, Z1 to Z4] Color Masterbatch Composition 
     Carbon black (30 wt %) was added to the pulverized thermoplastic polyester granules (70 wt %), and further subjected to extrusion kneading at 240-280° C. in a twin-screw extruder to obtain the color masterbatch composition of comparative example CB. In addition, the colorants were added to the pulverized thermoplastic polyester granules according to the content ratios in Table 3 below, and then subjected to extrusion kneading at 240 to 280° C. in a twin-screw extruder to obtain the color masterbatch compositions of comparative examples Z1 to Z4.

     Application Examples 
     [Application Example 1] PET Colloidal Particle 
     The color masterbatch compositions of the above implementation examples A1 to A32, B1 to B32, C1 to C32 and D1 to D32 were pelletized and then added to PET for color development (the color masterbatch composition accounted for 6 wt % of the total weight) to obtain the PET colloidal particles PET A1 to A32 , PET B1 to B32 , PET C1 to C32  and PET D1 to D32  of application example 1. 
     [Application Example 2] Fiber 
     The PET colloidal particles PETA 1 to A32 , PET B1 to B32 , PET C1 to C32  and PET D1 to D32  of above application example 1 were drawn at 285 to 300° C. to obtain fibers F A1 to A32 , F B1 to B32 , F C1 to C32  and F D1 to D32  (the fiber fineness is 3 DPF) of application example 2, where fibers F A1 to A32  and F B1 to B32  are black, and F C1 to C32  and F D1 to D32  are dark grey, which can be suitable for dark textiles. 
     [Application Example 3] Prepreg 
     The PET colloidal particles PET A1 to A32 , PET B1 to B32 , PET C1 to C32  and PET D1 to D32  of the above application example 1 were shot at 285-300° C. to obtain the prepregs S A1 to A32 , S B1 to B32 , S C1 to C32  and S D1 to D32  of application example 3, where the prepregs S A1 to A32  and S B1 to B32  are black, and the prepregs S C1 to C32  and S D1 to D32  are dark gray, which can be applied to dark engineering plastics. 
     Comparative Application Examples 
     [Comparative Application Example 1] PET Colloidal Particle 
     The color masterbatch composition of the above comparative example CB and Z1 to Z4 was pelletized and then added to PET for color development (the color masterbatch composition accounted for 5.5 wt % of the total weight) to obtain the carbon black PET colloidal particles PET CB  and black PET colloidal particles PET Z1-Z4  of comparative application example 1. 
     [Comparative Application Example 2] Fibers 
     The carbon black PET colloidal PET CB  of comparative application example 1 and the black PET colloidal particles PET Z1 to Z4  of comparative application example 2 were drawn at 285 to 300° C. to obtain fibers F CB  and F Z1 to Z4  of comparative application example 3, respectively, where the fibers F Z1 to Z4  are all faded and close to brown, and cannot be directly applied to dark textiles. 
     Test Examples 
     Infrared Heating Tests 
     The PET colloidal particles are irradiated at 23° C. with an infrared lamp (Philips PA 38 I Red 150W 125-130V, wavelength range 600 to 1400 nm) at a distance 17 cm between them for 55 minutes, and an infrared thermometer is used to measure the temperature of the PET CB  of the above comparative application example 1 and the PET colloidal particles of application example 1 every 5 minutes, respectively, and the results are shown in Table 4 below.

     The infrared heating test results of Table 4 show that the temperature of PET A1-A32  prepared by using the color masterbatch composition of the disclosure is below 67° C. after 10 minutes of infrared absorption and below 74° C. after 55 minutes of infrared absorption, while the temperature of the carbon black PET colloidal particle PET CB  prepared by carbon black has already been higher than 100° C. after 10 minutes of infrared absorption, which indicates that the heating rate is faster and the temperature rise is larger. 
     In addition, the heating test results of PET B1 to B32 , PET C1 to C32  and PET D1 to D32  were similar to those of PET A1 to A32 , respectively. The above experimental results show that the color masterbatch composition of the disclosure can slow down and reduce the heating effect caused by infrared absorption. 
     In summary, the color masterbatch composition of the present disclosure can slow down and reduce the temperature rise effect caused by absorbing infrared rays without additionally adding other heat dissipating materials or modifying, and Its original color can still be maintained during the processing of preparing fibers or plastics such that it is suitable for the preparation of dark textiles or engineering plastics, so it is indeed possible to achieve the objects of the present invention. 
     The above is only the embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made in the claims and the description of the present invention still fall in the scope of the present invention.
