A process for continuous production of partly crystalline polycondensate pellet material which comprises the step of crystallizing the pellet material in a second treatment space (6a) under fixed bed conditions by supply of energy from the exterior by means of a process gas, wherein the process gas has a temperature (T.sub.Gas), which is higher than the sum of the pellet temperature (T.sub.GR) and the temperature increase (T.sub.KR) which occurs due to heat of crystallization released hi the second treatment space (6a), i.e., (T.sub.Gas>(T.sub.GR+T.sub.KR)). The pellets at the exit from the second treatment space (6a) have an average temperature (T.sub.PH), which is 10 to 90 C. higher than the sum of the temperature of the pellets (T.sub.GR) and the temperature increase (T.sub.KR) which occurs due to heat of crystallization released in the second treatment space (6a), i.e., (T.sub.GR+T.sub.KR+90 C.)T.sub.PH(T.sub.GR+T.sub.KR+10).

A method for manufacturing a tableware article having a thermal-transfer printed pattern includes the following steps. Firstly, a PET resin composition including 3 to 15% by weight of an inorganic filler is provided. Next, the PET resin composition is granulated to obtain plastic granules. Then, the plastic granules are molded into the tableware article and the tableware article is post-crystallized. Finally, a thermal transfer printed pattern is printed on a surface of the post-crystallized tableware article.

Methods for producing spatial objects are disclosed. The methods generally include printing a spatial object, in an amorphous phase, using a three-dimensional (3D) printer and a printing material that consists essentially of polyaryletherketones. The methods further entail placing the spatial object in a container and submerging the spatial object in a suitable charging material. Next, vibrations are applied to the container that includes the spatial object and charging material. The container, charging material, and spatial object are then heated until the spatial object transitions into a semi-crystalline phase (at which point the spatial object can be removed from the container and charging material).

A crystallized bioabsorbable polymer scaffold comprises a polymer composition of poly (L-lactide-co-tri-methylene-carbonate) or poly (D-lactide-co-tri-methylene-carbonate) or poly (L-lactide-co--caprolactone) or poly (D-lactide-co--caprolactone) in the form of block copolymers of blocky copolymers, wherein the scaffold is cold-bendable.

Methods are provided for making and recycling recyclable food grade plastic products from recycled, post-consumer plastic. The recyclable food grade plastic products may have wash away labels with printed text, graphics, or images that can be easily removed such that the plastic product may be recycled into FDA-approved food grade (i.e., food safe) plastic that is capable of being reused to manufacture new recyclable food grade products.

Methods of marking plastic-based products and marked plastic-based products are provided. Some methods include irradiating the product to alter the functionalization of the plastic.

Provided is a semiaromatic polyamide fil having an average linear expansion coefficient in the width direction, measured under conditions of 20 to 125? C., of ?90 to 0 ppm/? C.

A composite pipe comprises a polyetheretherketone innermost pipe around which a reinforcing overwrap is arranged. A protective sheath surrounds the overwrap. Such a composite pipe may be made by selecting a polyetheretherketone pipe having an outer region having a crystallinity of less than 25%; overlaying the selected pipe with overwrap; and subjecting the combination to heat, thereby causing the crystallinity of the outer region of the polyetheretherketone pipe to increase. The method reduces the risk of pipe failure.

A method of making carbon fiber material according to various embodiments of the present disclosure includes forming a polymer resin to have a polydispersity index (PDI) that is less than approximately 2.5. The method further includes spinning the polymer resin to create an acrylic fiber having an acrylic fiber length. The method further includes oxidizing the acrylic fiber while stretching the acrylic fiber to create an oxidized fiber that has an oxidized fiber length that is at least one of greater than or equal to approximately 100 percent (100%) of the acrylic fiber length. The method further includes carbonizing the oxidized fiber to create a carbon fiber.

The present disclosure relates to methods and systems for making thermoplastic resin materials and composite resin systems and materials made from the thermoplastic resins, by seeding one melted thermoplastic material with a second thermoplastic material in a crystalline state that comprises an amount of ferromagnetic material.
