Abstract: This corespun yarn includes a high temperature resistant continuous filament fiberglass core and a low temperature resistant staple fiber sheath surroudning the core. The corespun yarn is useful in the formation of fine textured fire resistant flame barrier fabrics for use as mattress and pillow ticking, bedspreads, mattress covers, draperies, upholstery, protective apparel, tenting, awnings, field fire shelters, for use as a substrate or backing for coated upholstery fabrics and as a flame barrier for use beneath upholstery fabric. The core of high temperature resistant continuous filament fiberglass comprises about 20% to 40% of the total weight of the corespun yarn while the sheath of low temperature resistant staple fibers surrounding and covering the core comprises about 80% to 60% of the total weight of the corespun yarn. The total size of the corespun yarn is within the range of about 43/1 to 3.5/1 conventional cotton count.

Abstract: The present friction spinning apparatus includes a draw frame section with an entrance trumpet including first and second fiber sliver guiding passageways for forming a three component corespun yarn. One of the guiding passageways directs a core roving into the draw frame section while the other sliver guiding passageway directs a core wrapper sliver into the draw frame section so that the core wrapper fibers surround the core fibers. Wrapping fibers are then wound about the core and core wrapper fibers in an elongated throat extending between a pair of rotating suction drums.

Abstract: A method for increasing heat dissipation from the smolder or open flame site of an upholstered article by interposing a fire barrier material between the outer upholstery fabric and the filler or padding materials. The fire barrier material is formed by coating a fibrous substance, such as glass fibers, carbon fibers, and the like with a latex containing a finely divided heat conductive metal.

Abstract: The mattress pad and fitted bed sheet (31) are formed by placing equal lengths of mattress pad material (58) and bed sheet material (61) in overlying relationship and sewing the narrower mattress pad material at its side edges to the sheet material. The combined work product is then cut to length, the end portions folded over, and the corners bevelled and sewn together. An elastic tape (48, 49) is applied to each end of the work product so as to draw the mattress pad and fitted bed sheet about the mattress. The structure enables the mattress pad and fitted bed sheet to stay in proper position even when applied to a foldable mattress (24) of a sofa bed (20), when the mattress is folded into its hidden position inside the sofa bed.

Abstract: Textile yarns are treated with a sizing composition which, when dried and cured, remains durably bound to the yarn throughout wet finishing operations and subsequent use. The sizing composition comprises an aqueous self-crosslinking emulsion copolymer derived from at least one ethylenically unsaturated monomer and a latent-crosslinking monomer. The sizing composition may also include a water soluble or dispersible film forming polymer and a reactive resin. The durable size coating beneficially contributes to both the physical and the aesthetic properties of the yarn and fabrics formed therefrom.

Abstract: The fitted bed sheet (22) and mattress pad (30) are connected together along the side edges (47 and 48) of the pad by stitching (49). The length of the pad and bed sheet are the same so that the foot and head portions (32 and 33) of the pad extend into and form a part of the foot and head skirts (25 and 26) of the pad-sheet (20). An elastic hem (35 and 36) is formed about the edges of the skirt at the foot and head of the pad-sheet.

Abstract: A woven textile fabric having at least 65% thermoplastic fibers therein with an ultrasonically cut and sealed edge characterized by a wash durability of preferably at least 25 to 50 washings without significant raveling. Apparatus and processes are provided for effecting such ultrasonic cutting and sealing to produce the desired cut and sealed edge in the woven textile fabric.

Abstract: A method for preventing discoloration of durable press fabrics containing cellulosic fibers that have been previously finished using a non-formaldehyde finishing agent such as glyoxal in which the fabric is treated with an oxidative afterwash solution at elevated temperature followed by neutralization, rinsing and drying. The oxidative afterwash treatment may be performed in a continuous process as part of or immediately following the durable press finishing operation, or at a later time in a totally separate process.

Abstract: A finishing process for textile fabrics is disclosed which imparts to the fabric reduced permeability to down, fiberfill or other insulating materials. A curable finishing formulation containing silicone compounds and filler materials is applied to the fabric, dried and cured and the fabric may thereafter be calendered.

Abstract: Textile materials containing cellulosic fibers are provided with durable press properties by reacting and crosslinking the cellulosic fibers with a durable press finishing agent consisting essentially of a silicone compound and a silicone fragmentation reactant in an effective amount to fragment the silicone compound when exposed to curing conditions. The fabric is impregnated with a finishing bath containing the durable press finishing agent and the fabric is heated to fragment the silicone compound and react and crosslink the finishing agent with the cellulosic fibers to impart durable press properties to the fabric.

Abstract: A method of printing textile fabrics, especially precolored fabrics of relatively dark shades, wherein a printing paste containing pigments and a heat curable binder is applied to selected areas of the fabric and the printing paste is thereafter dried and cured, said method being characterized by obtaining washfast, opaque printed areas substantially unaffected by the color of the underlying yarns, and by achieving high chroma, even on relatively dark background shades, said method comprising applying to the fabric an aqueous printing paste having a total solids content of at least 25 percent and comprising an aqueous dispersion containing a curable polymer binder, an opacifier containing at least one opaque pigment with minimal tinctorial value and a refractive index of less than 1.

The apparatus and process are characterized by cutting off a predetermined width of the undesirable selvage from each side of the textile fabric regardless of the transverse variations in the path of travel of the fabric through the apparatus or width of the fabric. The apparatus utilizes a mechanism for shifting the moving textile fabric relative to a stationary ultrasonic cutting and sealing mechanism on one longitudinal edge of the fabric and a mechanism for shifting a movable ultrasonic cutting and edge sealing mechanism relative to the other longitudinal edge of the moving textile fabric.

Abstract: The level of released formaldehyde in a durable press treated fabric is significantly reduced or eliminated altogether by an oxidative aftertreatment process in which the fabric, after treatment with a formaldehyde-based durable press finishing agent and curing to impart durable press properties, is contacted with an oxidizing agent to destroy formaldehyde-releasing moieties present in the fabric. Preferably, the treatment of the durable press fabric with the oxidizing agent is carried out by impregnating the fabric with a solution containing the oxidizing agent and then providing the fabric a residence time in contact with the oxidizing agent to allow for reaction of the oxidizing agent with the formaldehyde-releasing moieties.
