A sensor yarn (10) having a thread core (11) around which first and second conductors (12, 13) are helically wound. The two conductors (12, 13) are electrically insulated from each other and from the thread core (11). The two conductors (12, 13) form a capacitive component (15) together with the thread core (11). In one embodiment, the sensor yarn (10a) has a capacitance (Cl) per unit of length that changes in the direction of extent (E) of the sensor yarn. This can be accomplished by a change in the winding geometry of the first or second conductors (12, 13) or by a change of the relative permittivity (E) of the sensor yarn (10). In another embodiment, the sensor yarn (10b) has photosensitive material (30) and a length change is effected by an incident to the light (L). As a result of a length change or other deformation of the sensor yarn (10a, 10b), the total capacitance (CG) of the sensor yarn (10a, 10b) changes, which can be determined by means of an evaluating unit (17).

The invention discloses a method for preparing a hollow textile with a core-spun yarn of short-staple wrapped microporous alkali-soluble polyester filament, which includes a foaming microcapsule preparation step, a preparation step of alkali-soluble chips containing foaming microcapsules, a melt foaming and spinning step, and a hollow textile preparation step. In the method for preparing the hollow textile with the core-spun yarn of short-staple wrapped microporous alkali-soluble polyester filament, a hollow yarn or a hollow fabric is made from a polyester filament having a microporous structure through alkali dissolution. The polyester filament having a microporous structure can effectively increase the contact area of the alkali dissolution and has the advantages of high dissolution rate, short dissolution time and complete dissolution. The hollow textile prepared from the hollow yarn or the hollow fabric obtained after dissolution has a comfortable hand feeling and has the characteristics of being fluffy, soft, warm and quick-drying.

A structure includes an oriented piezoelectric polymer arranged in a circular tubular or circular columnar shape, wherein the orientation angle of the piezoelectric polymer with respect to the central axis of the structure is 150 to 750, the piezoelectric polymer includes a crystalline polymer having an absolute value of 0.1 to 1000 pC/N for the piezoelectric constant d14 when the orientation axis is the third axis, and the piezoelectric polymer includes a P-body containing a crystalline polymer with a positive piezoelectric constant d14 value and an N-body containing a crystalline polymer with a negative value, wherein for the portion of the central axis of the structure having a length of 1 cm, the value of T1/T2 is 0 to 0.8, T1 being the smaller and T2 being the larger of (ZP+SN) and (SP+ZN), where ZP, SP, ZN, and SN are particularly defined masses.

A woven article for a carbon fiber reinforced plastic according to the present invention is a woven article of a spun yarn containing: about 10 wt % to about 60 wt % of a carbon fiber staple in which the content of carbon components is equal to or greater than about 97 wt %; and about 40 wt % to about 90 wt % of a thermoplastic resin fiber, wherein the carbon fiber staple is obtained by carbonizing carbon fiber reinforced plastic scrap at a temperature of about 900 to about 1400 C. The woven article for a carbon fiber reinforced plastic includes a carbon fiber staple manufactured from scrap generated during manufacture of the carbon fiber reinforced plastic, and allows economic recycling of the carbon fiber reinforced plastic scrap without a reduction in mechanical properties. When molded, productivity is high due to a short cycle time, there is almost no orientation, and an excellent flexural modulus is exhibited.

The invention relates to a woven fabric comprising a weft yarn and at most two warp yarns A and B, wherein the weft yarn comprises a high performance fiber; the warp yarn A comprises at least 50 wt % of a natural fiber; the warp yarn B comprises a high performance fiber; and wherein the fabric has an outside layer comprising the warp yarn A and an inside layer comprising the warp yarn B and said outside and inside layers being at least partially interconnected by the weft yarn. The invention also relates to products comprising said woven fabric such as clothing, lining, sport apparel, gloves, curtains, upholstery fabric and floor covering.

Textiles for endovascular and other medical applications having a low-profile are provided. The textiles are woven, knit or braided and are formed of yarns having low (<17) denier and high tenacity (at least 7 grams per denier). The resulting textiles have a low profile, high suture retention and extremely low water permeability.

Provided is a multiple gauze fabric having excellent friction strength while maintaining skin feel like twistless yarn fabric. The multiple gauze fabric is constituted from a first gauze structure as a front surface, a second gauze structure as a back surface, and a third gauze structure as an intermediate layer. The first gauze structure is formed using a first twisted yarn as a warp, and using a second twisted yarn as a weft. The second gauze structure is formed using a third twisted yarn as a weft, and a fourth twisted yarn as a warp. The third gauze structure is formed using a fifth twisted yarn as a warp, and a sixth twisted yarn as a weft. The twist coefficient of second and fourth twisted yarn is 3.0 or less. The twist coefficient of first, third, fifth and sixth twisted yarn is 3.3 or more.

A method of making a yarn is disclosed. A plurality of fibers is obtained by: preparing a slurry of polymer mixed with water insoluble nanoparticles of electrolytic copper, and extruding the slurry through a spinneret that includes a plurality of holes which impart a generally X-shaped cross-section to the plurality of fibers. The plurality of fibers are spun together to form the yarn.
