摘要:
An apparatus and method for making a low cost, self-venting, inflatable protective cushion of simple and structurally efficient design with a shape and construction that optimizes the cushion's ability to withstand inflation pressures and impact when deployed which includes a sheet defined by at least one fold line and a plurality of flap portions, each flap portion having a base edge corresponding to a fold line and at least two side edges each extending outwardly from a base edge and ultimately converging to meet each other, the flap portions being folded at the fold line(s) and being Joined at corresponding side edges to define an inflatable chamber. The inflatable protective cushion and method for making same may further include a lightweight, low permeability, fabric that optimizes the cushion's ability to withstand inflation pressures and impact when deployed and minimizes the packed volume of the cushion when stored.

A fluid jet applicator is disclosed which senses orifice plate fluid pressure and the fabric substrate speed and electronically controls the flow of fluid by modulating fluid pressure in accordance with the speed and characteristics of the fabric substrate. In this fashion, a highly uniform solid shade is applied across the width of the fabric. The uniformity of the applied solid shade is limited only by the uniformity of the orifices in the applicator orifice plate. Additionally, by operating at higher fluid pressures than electrostatic fluid jet applicators, the present invention is significantly more productive than such electrostatic applicators.

The electrostatic fluid jet applicator of the present invention achieves patterning effects with an applicator designed to provide a uniform solid application of liquid onto substrates. The applicator requires no digital memory device to store extensive image data defining patterns to be printed and includes a single ganged charging electrode which is utilized to simultaneously charge (or not charge) droplets emanating from a linear array of orifices. The applicator generates patterning effects primarily by controlling the application of charging voltage to the single electrode and by controlling the print time.

Cotton-containing toweling is dyed in a dye bath solution containing a coloring amount of at least one phosphonic acid fiber reactive dye together with sufficient acids such that the fiber reactive dye reacts with and attaches to the cotton of the toweling. The deybath-saturated toweling is passed through a high expression roll until the wet pickup is in the range of about 40-55 percent wpu, and then the toweling is heated to a temperature of at least 200 degrees F. for a time sufficient to fix the dye onto the cotton producing a fully penetrated, evenly dyed toweling. The toweling may be printed in a predetermined pattern with a print paste after passage through a high expression roll and before final heating.
摘要:
A hybrid fluid jet apparatus is disclosed which is particularly useful in uniformly applying liquid dye to a fabric substrate. The applicator is controlled in an electrostatic control mode while operating below the practical limit of speed for electrostatic operation to achieve uniform fabric coverage. When fluid is being supplied to the substrate at its maximum flow rate in the electrostatic control mode, the applicator senses that the "full flow" condition has been reached. The applicator is then controlled to operate in a non-electrostatic control mode to control the fluid flow rate by modulating the fluid pressure received at the orifice array in accordance with the required fluid flow rate needed to achieve a uniform application of fluid to the substrate.
摘要:
Uniform application of a controlled relatively small liquid volume per unit area to a moving fabric substrate is obtained even though application is made using a liquid jet electrostatic applicator which employs random drop formation processes. Repetitive print times during which randomly formed droplets are passed onto the substrate along a linear orifice array are controlled so as to have a minimum duration sufficiently large as to average out expected random variation in droplet formation processes occurring along the orifice array. At the same time, the center-to-center spacing of each printed pixel (during which randomly formed droplets are intercepted so as not to fall onto the substrate) is controlled so as to maintain a desired relatively small controlled liquid volume per unit area within the fabric substrate section to be printed. In one exemplary embodiment, the print times are maintained in excess of approximately 200 microseconds and/or so as to insure that the expected standard deviation of liquid volume printed onto the substrate during each print time is less than approximately 0.2.
