In order to give a resin molded product made of resin, etc., a high-class feeling, flocked feeling, matte feeling, etc., mix with these resins a high melting point or non-melting fugitive fiber cut into an appropriate length Is being done. Conventionally, rayon has been mainly used as such a raw fiber, but rayon has a high hygroscopic property, and when this is mixed with a resin and molded, water contained in the fiber is vaporized and foamed. Therefore, there was a problem that many defective products occurred. In addition, rayon is expensive and it is difficult to prepare a large number of brands having different fineness and color tone due to restrictions in the manufacturing process.

It is solved by using a synthetic fiber as a raw material of hydrophobic synthetic fiber by melt spinning such as polyester and nylon. And
For this purpose, it is advantageous to use polyethylene terephthalate (PET) fiber, which is relatively inexpensive and has a high melting point, among general-purpose synthetic fibers. However, when the ordinary undyed PET fiber is used, a part of the colorant bleeds out when blended with the molding resin and molded, and a molded product having a good marbling feeling cannot be obtained.

It is intended to provide a polyester original fiber and a resin composition containing the original fiber, which gives a molded article having a good marbling feeling without bleeding out.

As a colorant to be contained in T, it is necessary to use a pigment having no solubility in PET. Examples of such pigments include carbon black, perylene red, azo yellow, phthalocyanine blue, phthalocyanine green, anthraquinone brown, and titanium dioxide.

品が得られる。When a colorant having a solubility in PET is used as the colorant, a phenomenon occurs in which a part of the colorant bleeds out to cause color transfer when blended in a molding resin and melt-molded. This phenomenon is more remarkable as the molding temperature is higher, and can be suppressed by lowering the molding temperature, but when the molding temperature is lowered, the melt viscosity of the resin increases and the moldability deteriorates, which is good. Cannot be obtained. Original PET fiber using a pigment that is not soluble in PET as a colorant is close to the melting point of PET 220 to 24.
Bleed-out of the colorant does not occur even when molding is performed at a high temperature of about 0 ° C. When this is used, a molded product having a good marbling feeling can be obtained.

リマーの粘度が低下したりして好ましくない。The amount of the pigment contained in the PET varies depending on the intended color tone, but it is usually suitable to be 0.1 to 3% by weight. If the pigment concentration is less than 0.1% by weight, not only sufficient coloring cannot be obtained, but the color itself may change depending on the type of pigment. On the other hand, the pigment concentration is 3% by weight
When it exceeds, the dispersibility of the pigment in the fiber is deteriorated and the viscosity of the polymer is lowered, which is not preferable.

If it exceeds mm, a molded product with a good marbling feeling cannot be obtained, and it becomes difficult to uniformly disperse the resin in the resin.
