[Problems to be Solved by the Invention]
An object of the present invention is to have excellent dispersibility of particles in polyester and substantially no coarse particles, and therefore, excellent molding processability in making fibers, films, and resin molded products, in the case of fibers. Has less single thread breakage, is excellent in slipperiness, film surface uniformity and abrasion resistance in the case of film, and is excellent in dimensional stability and impact resistance in the case of resin molded products, and is a base. is to provide a method for easily producing a polyester composition intrinsic viscosity is kept high in pairs to a polymer.
また、ポリエステル（Ａ）樹脂と、追加添加するポリエステル（Ａ）樹脂及び／又はポリエステル（Ｂ）樹脂との重量比は粒子の種類、運転条件及び目的とする製品の品質に従って最良の条件に設定すれば良く、ベント付き混練押出機内へ上記樹脂を追加添加する位置については、ポリエステル（Ａ）樹脂と粒子とが混練ゾーンを通過した後から、該混練押出機内における最終混練ゾーンより前であれば、即ち、少なくとも、ポリエステル（Ａ）樹脂と粒子との組成物と、追加添加した樹脂とが混練されるのであれば、いずれの場所に設定しても問題は無い。しかし、ポリエステル（Ａ）樹脂と粒子とが混練ゾーンを通過した後からベント孔より前の間の任意の場所に設定することが好ましい。 Further, the weight ratio of the polyester (A) resin to the polyester (A) resin and / or the polyester (B) resin to be additionally added should be set to the best condition according to the type of particles, operating conditions and the quality of the target product. As for the position where the above resin is additionally added into the vented kneading extruder, if it is after the polyester (A) resin and the particles have passed through the kneading zone and before the final kneading zone in the kneading extruder. That is, at least, as long as the composition of the polyester (A) resin and the particles and the additionally added resin are kneaded, there is no problem even if they are set in any place. However, it is preferable that the polyester Le (A) resin and particles is set anywhere between the pre-vent hole from after passing through the kneading zone.
［実施例２］
実施例１において、酸化チタン粒子を、粒子の全重量を基準として０．１５ｗｔ％のトリメチロールプロパンをその表面に吸着被覆させた、平均粒径０．３２μｍのアナターゼ型酸化チタンを、更に、全重量を基準として６０重量％の粒子濃度を有する水／テトラヒドロフラン（重量比９／１）を分散媒とするスラリーとし、該スラリーをサンドミルを通過させて実質５μｍ以上の粗大粒子を除去して後、４２ｋｇ／ｈの流量にて供給したこと以外は同様の操作を行ってポリエチレンテレフタレート樹脂組成物を得た。得られた組成物をペレット化して、固有粘度０．５９０のポリエステル組成物ペレットを得た。このポリエステル組成物ペレットを用いて特性を評価した結果を表１に示す。
[Example 2]
In Example 1, titanium oxide particles, a 0.15 wt% of trimethylolpropane based on the total weight of the particles adsorbed coating on the surface thereof, an anatase type titanium oxide having an average particle size of 0.3 2 [mu] m, further A slurry using water / tetrahydrofuran (weight ratio 9/1) having a particle concentration of 60% by weight based on the total weight is used as a dispersion medium, and the slurry is passed through a sand mill to remove coarse particles having a substance of 5 μm or more. After that, the same operation was carried out except that the particles were supplied at a flow rate of 42 kg / h to obtain a polyethylene terephthalate resin composition. The obtained composition was pelletized to obtain polyester composition pellets having an intrinsic viscosity of 0.590. Table 1 shows the results of evaluating the characteristics of the polyester composition pellets.
