    Abstract: A method includes charging PET bottle flakes having particular characteristics as a raw material into a crystallizer to generate a crystalline version thereof, drying the crystalline version with dehumidified air at a temperature of 160-180° C. and with a dew point of −40° C. to bring down a moisture level thereof below 100 ppm, melting the dried crystalline version through an extruder configured to have a temperature therein maintained at 285-295° C., and feeding the melted raw material into a spin beam. The method also includes generating, through a spinneret, a number of filaments based on extruding, through the spinneret, the melted raw material fed into the spin beam, forming a yarn based on combining the number of filaments, and winding the formed yarn to generate a spool of Partially Oriented Yarn (POY) configured to be utilized as another raw material to generate a Draw Texturized Yarn (DTY).

    Abstract: A method includes drawing a roving thread from a roving bobbin through a roving guide, an aft drafting roller, and a mid drafting roller to a front drafting roller, and drawing a spandex core from a spandex bobbin using a guide roller. The method also includes associating the roving thread and the spandex core by drawing the roving thread and the spandex core in an approximately parallel fashion through the front drafting roller, and drawing the associated roving thread and the spandex core through a lappet hook and an anti-ballooning guide. Further, the method includes winding the drawn associated roving thread and the spandex core on a ring-frame bobbin including a ring traveler attached to a rotatable ring. The circular motion of the ring traveler around the ring-frame bobbin causes the drawn associated roving thread to twist around the drawn associated spandex core, forming a core spun yarn.

    Abstract: A fluid dispenser is disclosed herein. An example of such a fluid dispenser includes a housing configured to store a quantity of fluid and an ejection assembly configured to controllably emit the fluid through a nozzle. The fluid dispenser also includes a fluid chamber configured both to supply a quantity of the fluid to the ejection assembly and to define a fluid flow path between the housing and the ejection assembly. The fluid dispenser further includes a filter positioned in the fluid flow path and configured both to conduct the fluid from the housing to the fluid chamber and to restrain particles in the fluid from entering the fluid chamber. The filter is further configured to define a bubble flow path that facilitates conduction of bubbles from the fluid chamber to the housing. Additional features of this fluid dispenser are disclosed herein, as are other examples of fluid dispensers.

    Abstract translation: 本文公开了流体分配器。 这种流体分配器的示例包括构造成存储一定数量的流体的壳体和构造成通过喷嘴可控地发射流体的喷射组件。 流体分配器还包括流体室，其配置为向喷射组件供应一定量的流体并且限定在壳体和喷射组件之间的流体流动路径。 流体分配器还包括位于流体流动路径中并被配置为将流体从壳体传导到流体室并且抑制流体中的颗粒进入流体室的过滤器。 过滤器进一步构造成限定有助于将气泡从流体室传导到壳体的气泡流动路径。 本文公开了该流体分配器的附加特征，以及流体分配器的其它示例。
