The present invention provides a resin composition having high heat-resisting properties, with which a shaping can be performed in accordance with designed sizes using a fused deposition modeling method-3D printer, and from which a shaped object having a small warpage and small changes in sizes due to water can be obtained. The present invention relates to a resin composition for a shaping material of a fused deposition modeling method-3D printer, comprising cellulose fibers in a polyamide.

Resin composition for shaping material of fused deposition modeling method-3D printer and filamentary molded body thereof

Provided is a polyamide resin composition including 0.01 to 50 parts by mass of cellulose fiber in relation to 100 parts by mass of a polyamide resin, having a relative viscosity of 2.3 or more, and having an L-value, an a-value and a b-value in an Lab color space of 20 or more, 10 or less and 20 or less, respectively. The aforementioned polyamide resin composition is obtained by subjecting a polyamide resin composition having a relative viscosity of 2.2 or less to a solid phase polymerization.

Polyamide resin composition

Disclosed is a polyamide resin composition comprising 0.01 to 50 parts by mass of cellulose fiber having an average fiber diameter of 10 &#x3bc;m or less in relation to 100 parts by mass of a polyamide resin. Also disclosed is a method for producing the polyamide resin composition, wherein the monomer constituting the polyamide resin is subjected to a polymerization reaction in the presence of the cellulose fiber having an average fiber diameter of 10 &#x3bc;m or less in a water-containing state.

Polyamide resin composition and method for producing polyamide resin composition

Disclosed is a biodegradable resin composition improved in water barrier properties. Also disclosed is a molded body formed from such a resin composition. The biodegradable resin composition comprises 100 parts by mass of a biodegradable polyester resin and 0.1-15 parts by mass of a jojoba oil and/or a polar wax. The biodegradable polyester resin may contain not less than 50% by mass of a plant-based resin. Polylactic acid can be used as the plant-based resin.

Biodegradable resin and product molded or formed from the same

A biodegradable gas barrier vessel comprising 100 parts of mass of a biodegradable polyester resin having a polylactic acid content of not less than 50% by mass and 0.1 to 10 parts by mass of a phyllosilicate. The degree of crystallization as measured by X-ray diffractometry is not less than 15%, and the coefficient of oxygen permeation as measured under conditions of 20&#xb0; C. and relative humidity 90% is not more than 50 ml&#xb7;mm/m&#xb7;day&#xb7;MPa. Since the biodegradable polyester resin reinforced with the phyllosilicate has excellent heat resistance, the molded product can be heat treated at an elevated temperature. Such enhanced heat treatment conditions can further enhance the degree of crystallization of the polyester resin and thus can contribute to significantly improved gas barrier properties.

Biodegradable gas barrier container and process for producing the same

A biodegradable resin composition is provided, which is highly transparent with little agglomeration. The biodegradable resin composition comprises a biodegradable polyester resin, a phyllosilicate, and at least one of a polyether phosphate compound, a polar wax and jojoba oil.
