A method to form yarn via film fiberizing spinning belongs to a textile technical field. A film cutting device is arranged behind each drafting system on a ring frame, whose cut resistance apron and cutting roller engage with each other to form a cutting zone to cut and fiberize the film to get belt-like multi-filaments. Then the multi-filament formed passes through the first, second and third drafting zones in sequence for drawing, in such a manner that the multi-filament molecular orientation and crystallization are improved. After being drafted, the multi-filaments are twisted into yarn by ring spinning, which provides a novel high-efficient and short-processing way of producing yarns of nano-micro fibers using films instead of conventional nano-spun fibers such as electro- and centrifugal spun fibers, thereby breaking restriction of “low bulk and low-speed production of nano-spun fibers” and integrating the film industry with the textile industry.

The invention relates to a material sheet comprising a woven fabric of polymer tapes, wherein the width of a tape varies less than 2% on average in the longitudinal direction of the tape. The invention also relates to a process for the preparation of the material sheet, and to a ballistic resistant article comprising the material sheet. A ballistic resistant article comprising the material sheet exhibits excellent antiballistic properties.

A new method for manufacturing a new foil lame′ fabric (1) accepts lame′ fabric that had been treated to accept binder, (2) applies binder to one side of the lame′ fabric, (3) arranges hot stamping foil on the side of the lame′ fabric to which binder had been applied, to define an arrangement (wherein the hot stamping foil includes a carrier), (4) hot presses the arrangement of hot stamping foil and lame′ fabric to create a foil-lame′ combination, (5) cures the foil-lame′ combination, and (6) removes the carrier from the foil-lame′ combination. The lame′ fabric accepted may be prepared by (1) treating a tinted polyester metalized film to accept a binder adapted to accept a clear hot melt adhesive to define a treated film, (2) slitting the treated film, (3) winding the slit, treated film onto bobbins, and (4) weaving the slit, treated film with nylon yarn to produce the lame′ fabric. The hot stamping foil may be prepared by (1) treating a clear polyester base film with a release coat, (2) tinting the treated clear polyester base film to a desired color, and (3) metalizing the treated and tinted clear polyester based film.

Novel woven materials, producible by a new weaving method, are described that comprise single or doubled warps and wefts in the form of tapes that are preferably partially stabilized type of fibrous tape. These fibres are caused to occur in a non-linear arrangement during the weaving process. The non-linear fibres can be subsequently straightened by pulling the tape longitudinally. The doubled warps and wefts comprise disconnected tapes. Such separateness of constituent tapes of doubled warp and weft tapes enables them to be slid/slipped relative to each other by pulling longitudinally and laterally without causing any alteration in the woven structure. These novel fabrics solve the problem of uneven fibre distribution and orientation arising from crumples/wrinkles due to compression and stretches due to extension, at the inner and outer sides respectively, when tape-woven fabrics are curved into shapes. Further, by using doubled warps and wefts fabrics with relatively flat/planar sections and thicker/raised wide rib sections can be also created that resemble a bit like a profiled material in its cross-section. Other fabrics like those comprising slant/oblique weft tapes, shaped warp and weft tapes, formed shape within its body are also producible.

Object: To provide an EMI suppression flat yarn, an EMI suppression article using the flat yarn, and a method for manufacturing the flat yarn and article that exhibit excellent flexibility, do not become cracked or rigid even when attached to curved portions, wire harnesses, or electrical cables, and enable electronic devices to be lighter, flatter, shorter, and smaller. Solution Means: An EMI suppression flat yarn including: an EMI absorbing polymer resin layer (I) capable of absorbing EMI, wherein a value of return loss (S11) as measured according to IEC-62333 is −1 dB or less over an entire range of EMI frequencies of 300 MHz to 18 GHz, and a value of transmission loss (S21) as measured according to IEC-62333 is −1 dB or less over an entire range of EMI frequencies of 300 MHz to 18 GHz; and a polymer resin layer (II) on one surface of the EMI absorbing polymer resin layer (I); or including a polymer resin layer (II) on one surface of the EMI absorbing polymer resin layer (I); and a polymer resin layer (III) on another surface of the EMI absorbing polymer resin layer (I); the EMI suppression flat yarn being formed into a fabric, knit, or braid; an EMI suppression article using the flat yarn; and a method for manufacturing the EMI suppression flat yarn and article using the flat yarn.
摘要:
Curled decorative grass having a variety of configurations and methods for making such decorative grass is provided which, because of its increased bulk, can also be used as a packing material, an animal bedding, cat litter, mulch for soil and a media for plants. The curled decorative grass is produced by curling a substantially flat sheet of material and thereafter cutting the resulting curled sheet of material, or by cutting a pre-curled material.

Devices and methods for twisting yarn may twist a strip of material, such as a paper strip, into a yarn, such as a paper yarn. Such devices and methods may involve positioning a pad formed from a roll of the material horizontally in a yarn twisting device, such that the strip of material is unwound and drawn from an outer circumference of the pad, but down through the center of the pad, and subsequently through a rotating yarn twister.
摘要:
A reinforcing member made from a fibrous material and disposed at least on one face of a strip-like expanded graphite to form a strip-like base member. The base member is stranded to be formed as a cord-like member. At this time, one side end edge of the base member is placed on the outer peripheral surface of the cord-like member, and, in the side end edge, the strip-like expanded graphite is more elongated in the width direction than the reinforcing member. The stranding of the base member is applied while the strip-like expanded graphite which is elongated in the width direction is placed on the inner side, and the reinforcing member which is short in the width direction is placed on the outer side. According to the configuration, both the reinforcing member and the strip-like expanded graphite are placed in a spiral manner to be alternately arranged in the axial direction on the outer peripheral surface of the cord-like member.
