摘要:
A composite camouflage composition includes a substrate and a plurality of individual strips of camouflage material being spaced apart and adhered to the substrate along a bonding axis, each strip of the plurality of individual strips of camouflage material presenting a plurality of lobes adjacent the bonding axis, each strip of the plurality of individual strips of camouflage material being gathered at points along the bonding axis such that more than one layer of each strip of the plurality of individual strips of camouflage material is adhered to the substrate at such points. A garment and a method of forming the camouflage composition is further included.

The present invention concerns weaving. In particular, it is a woven material produced using tape-like warp and tape-like weft through the employment of a rotary type shedding device which also functions as a direct specific-weave patterning device and a pick guiding device. The material according to the invention has a constructional constitution of at least some of the warp and weft that is non-homogenous. The invention also relates to a weaving device for producing woven material with tape-like warp and weft, comprising a rotary device, which is capable of producing more than one fabric simultaneously.
摘要:
Tuftable primary backings comprise a closed-weave, woven tape fabric to which is affixed a coherent web layer comprising staple fibers with fibers oriented in at least two directions and a plurality of the fibers being fused. The web layer is affixed to the fabric by penetration of fibers from the web into the fabric. The backings have substantial weftline straightness and stability against deformations in the machine, cross and off-axis directions. Improved tufted goods and methods for making the composites and tufted goods are also provided.

A material stock from which seals and packings may be formed is described; the material stock being relatively soft and compressible and cross section having a construction comprising a plurality of interlaced, as hereinbefore defined, flat section tapes having associated therewith a reinforcement. The tapes may include exfoliated graphite, paper, PTFE, mica, vermiculite as appropriate. The seal stock may have any desired cross sectional shape.
摘要:
A method for increasing the energy absorption of a fabric constructed of high tenacity fiber. This method modifies the ballistic stress-deflection curve of the fabric by effectively toughening the fabric by controlling the peak stresses generated in the fabric layer. These stresses are controlled by perforating the fabric into relatively narrow portions or cutting the fabric into relatively narrow strips, preferably along the bias. This unexpected property is counter-intuitive to known expertise in this area in that the weakening of the fabric by cutting or perforating actually improves the ballistic performance.

摘要:
Base consisting in a leno fabric, with flexible strips incorporated into it longitudinally, in the direction of the warp, linked successively through each one of the weft courses, in such a way that the threads of same evolve by passing from the face to the back of the fabric, and successively, with respect to adjacent strips, in accordance with a taffeta texture. The flexible strips are arranged in groups of two or more, regularly or irregularly spaced apart from each other and with respect to the connecting warp threads, defining open bands for the passage of air and light.

An erosion-control matting and method for making the matting wherein the matting is used for controlling certain erosion conditions, particularly with respect to erosion of soil and sand by the action of water. The matting is formed by cutting a vehicle tire into a continuous elongated strip and attaching at least two strips together, end-to-end, to form a continuous length of rubber striping which is then wound onto a spool. A multiplicity of strip-loaded spools are positioned longitudinally so as to be received in a weaving machine, with a single spool being positioned to dispense a rubber strip transverse to the longitudinally disposed rubber strips, whereby the strips are woven to form an interwoven rubber matting, the configuration thereof being predetermined for the required use.
摘要:
Formable twistless woven precursor fabrics, especially in satin or basket weave, made from flat tape of fiber reinforced thermoplastics on a power driven loom. The weft tape is supplied from a rotatable package that is driven in synchronism with the feeding mechanism and a finite tension on the tape is maintained.

A carrier membrane supports area covering solar cells and, preferably, is used for energy supply on a spacecraft. The membrane is stretched in a frame between two opposite sides and consists of plastic sheeting covered by a fiber-reinforced plastic fabric. To save weight, prevent insulation problems and thereby increase service reliability, the fabric is made of plastic reinforced with aromatic polyamide fibers in the form of woven crossing bands. The bands extend in the direction in which the membrane is stretched and transversely of the stretched direction. The bands extending in the stretched direction provide greater surface coverage than the bands extending transversely to
