Disclosed are a swab flocking device and a flock blowing and flocking process for a swab. A conveying drag chain transversely penetrates through a flocking box, several swab hangers are arranged on the conveying drag chain at intervals, and the conveying drag chain is connected to a first motor. Several blowers are arranged on an outer side of the conveying drag chain in the flocking box. During flocking, a swab stick is hung on the swab hanger and then is conveyed forwards by the conveying drag chain, and several blowers are configured to blow flocks onto an end head of the swab stick.

Methods of flocking and various embodiments of head-up displays for a vehicle are contemplated. Some embodiments of a head-up display unit can include a display unit configured to display an image onto an observation surface of a vehicle and trim structure located about a periphery of the display unit. The trim structure can have an exterior surface configured to be exposed to an interior compartment of the vehicle. A substantially uniform and continuous adhesive layer can be located directly on and in contact with an entire extent of the exterior surface. Flocking can be applied by an air gun such that flocking is dispersed directly on and in contact with the adhesive layer and such that no backing layer exists between the flocking and the exterior surface. Some embodiments of the methods of flocking can include spraying an adhesive and spraying flocking onto trim for a head-up display device.

A composition includes water, a polymeric adhesive dispersed in the composition, and a water-soluble polymer dissolved in the composition. The water-soluble polymer has a weight average molecular weight of at least 90,000 grams per mole. Typically, and advantageously, upon spraying the composition, the composition provides filaments including the polymeric adhesive and the water-soluble polymer. A process for making the composition, a method of using the composition, and a method for making a bonded article using the composition are also described.

Disclosed herein is a spray nozzle comprising an annular head, a hollow neck, and a liquid inlet line disposed in the hollow neck. The annular head comprises a liquid inlet orifice, first and second external flow diversion surfaces, an interior circumferential channel, and an ejector. The ejector comprises a substantially smooth surface having a fixed width, the ejector extending from the point of contact with the interior circumferential channel such that in the extending direction, the substantially smooth surface increases in distance from the interior circumferential channel. Also disclosed herein is an apparatus comprising at least one such spray nozzle, and processes comprising using at least one such spray nozzle.
