Abstract: Waterproof, moisture-vapor-permeable urethane-coated fabrics with durable antimicrobial properties that remain after repeated launderings are prepared by incorporating bioactive silyl quaternary ammonium salts into the polyurethane elastomer solvent solution that forms a microporous polyurethane layer by the wet coagulation method on a base fabric.

Abstract: A cardboard, paperboard, or fiberboard carton having a generally-rectangular parallepiped configuration is constructed and utilized so that even when the carton is deep, items packed at the bottom of the carton can be easily removed. Side panels of the parallepiped carton each have vertical corners extending along the lengths of its edges. The lines of separation are formed at the corners defining one of the side panels. The lines of separation, such as through-extending slits or perforations, are spaced from but near the top of the container (e.g., at a distance about one to four inches from the top of the container) and extend several inches toward the middle of the container, being spaced from the bottom. A horizontal score line may be provided at the bottom of the lines of separation, to facilitate bending over the side panel between the lines of separation once the top of the carton has been unpacked and it is desirable to unpack the bottom of the container.

Abstract: Flame retardant properties are imparted to a textile substrate by application of a powdered flame retardant in solid form, which is then fused or melted onto the textile to durably attach the flame retardant to the textile. The process is especially adapted for water-insoluble solid flame retardants, such as hexabromocyclododecane, currently applied in dispersion or emulsion form.

Abstract: Method and apparatus are disclosed relating to forming yarn by "vacuum spinning". A spinning nozzle assembly is provided which includes two axially aligned sections, each formed with a through passageway. Adjacent facing surfaces of the sections define a continuous radial slot through which air flow may be directed. The axially aligned sections of the nozzle are, in one exemplary embodiment, telescopically received within a sleeve mounted for rotation within a housing. The nozzle sections may be adjusted axially relative to each other to alter the dimension of the radial slot as desired, for example, in accordance with a predetermined yarn count.

Abstract: Disclosed are apparatus and methods for converting tow into sliver including cutter rolls for cutting fiber to length, a collector pan for passing the cut fiber from the cutting rolls to a drafting section and a pin roll in the drafting section for combing and debonding the fiber. The collector pan is shaped to dispose the opposite marginal edges of the cut fiber web in registration with the main body of the web to ensure proper presentation of the cut tow fibers to the drafting section. The pin roll in the drafting section includes a plurality of projections having leading and trailing edges terminating in a tip. Each leading edge is angled to enter the tow web prior to entry of the associated tip. The arrangement of the converter affords high weight delivery of combed and debonded fiber with minimal defects.

Abstract: A cold weather hat is formed of layered material comprised of an intermediate layer of open-cellular foam, an outer fabric layer, and an inner fabric. The hat has a high moisture vapor transmission rate. The hat has ear flaps which are constructed to conform to the configuration of the sides of an individual's face, eliminating the need for straps, and bill which is movable between upper and lower positions by a snap-type action. Peripheral vision is enhanced while the washer's head is kept warm.

Abstract: Vacuum spinning of yarn produces yarns having good properties, and which may have a wide variety of different effects and constructions. A core filament yarn may be fed into operative association with a nipped sliver or roving, and then fed to a perforated rotating hollow shaft operatively connected to the vacuum. The core filament yarn may be a full stretched textured yarn, which is placed under tension and while under tension is dragged over a sharp edge of nonconductive material, and after the tension is relieved develops crimp. This causes individual fibers to be repelled, and provides for intermixing of the nipped sliver or roving fibers and the core filament yarn fibers. Alternatively the filament yarn may be acted upon by draft rollers before the entrance to, and after the exit from, the hollow rotating shaft, to apply a force that breaks up to about 20% of the fibers. The yarns produced utilizing the broken fibers has a spun-like appearance.

Abstract: Synthetic textile fibers are dyed in a waterless coloring composition composed of a high-boiling ester solvent and a dye that (a) is soluble to the extent of at least 1.5% in the solvent, (b) provides a depth of coloration, expressed as yield, of at least 25%, (c) imparts to the dyed fibers a lightfastness value of at least 3, and (d) provides the dyed fibers with a washfastness value of at least 3.

Abstract: Breaking and/or test strength of aramid fabrics are enhanced when finished with a fabric softener. Improvements of up to 50% over the corresponding untreated greige fabrics and up to 45% over the corresponding untreated dyed fabric are achieved without detracting from flame resistance of these fabrics.

Abstract: Waterproof, moisture-vapor-permeable aromatic urethane-coated fabrics that resist degradation caused by ultraviolet light are prepared by incorporating hindered amine ultraviolet stabilizers into the aromatic urethane elastomer solvent solution that forms a microporous polyurethane layer by the wet coagulation method on a base fabric.

Abstract: A curtain, drape, shade, or the like movable to a position in which it has a ballooning effect is mounted in a simple and effective manner. A first conventional curtain rod supports a fabric sheet comprising the shade, or the like, at a top portion of the sheet. A second conventional curtain rod is spaced from the first rod and is adjacent the top of the sheet. A number of rings, disposed in columns, are formed on the back of the fabric sheet, and a cord passes through all the rings in a column. Each cord is connected at a first end to a bottom portion of the fabric sheet, and the second end of each cord passes through one or more eyelets mounted in a fixed position with respect to the second curtain rod. Each eyelet may be moved to any desired position along the curtain rod by loosening a screw fastener, and when the screw fastener is tightened it is fixed at the particular position to which it has been moved along the curtain rod.

Abstract: Synthetic/cellulosic blend textile fabrics are simultaneously dyed and the synthetic component simultaneously treated to impart flame resistance in a single step with good color yield. Additional fabric finishing may be used to impart flame resistance to the cellulosic component of the fabric.

Abstract: Aramid and aramid-blend fabrics are dyed and optionally flame-retardant treated using conventional pressure and heat dyeing equipment. Odor-free, colored or colored and highly flame resistant products result.

Abstract: A top bedsheet, bottom (fitted contour) bedsheet, or pillow case is produced by circularly knitting, in a jersey knit configuration, a sheath and core yarn into a fabric. The sheath fibers comprise short staple fibers such as cotton or comparable cellulosic fibers, and provide at least 50 percent of the yarn and preferably about 68-83 percent of the yarn. The core fibers are long staple synthetic fibers such as polyester, and are completely covered by the cotton so that the product has smoothness of hand. The fabric has a weight of approximately four ounces per square yard, and is finished so that it has a relaxed shrinkage of about five percent in both the length and width dimensions. The sheath and core yarn configuration is produced by passing a sliver of sheath fibers and a roving of core fibers through a trumpet, and then through the rear rolls, apron, and front rolls of a drafting apparatus to produce a drafted composite sliver, and then mechanically imparting a twist to the drafted composite sliver.

Abstract: A process for forming crepe fabrics on a shuttleless loom is provided which includes temporary stabilization of highly twisted (e.g., 40-70 TPI) filament yarn. To this end, hot melt size is applied at a predetermined temperature in predetermined amounts (e.g., add-on of about 10.5-13.5%) immediately after twisting so as to reduce the liveliness of the yarn and to thereby permit it to be woven. After weaving, the yarn stabilization is reversed by a desizing operation. The fabric is subsequently heat treated to develop crepe characteristics.
