Aspects herein are directed to a recyclable, asymmetrical-faced composite nonwoven textile suitable for use in apparel and other articles and methods of making the same. In example aspects, the asymmetrical-faced composite nonwoven textile includes a first face formed, at least in part from a first entangled web of fibers and an opposite second face formed, at least in part from a second entangled web of fibers. When incorporated into an article of apparel, the first face forms an outer-facing surface of the article of apparel, and the second face forms an inner-facing surface of the article of apparel. The first face includes features making it suitable to form the outer-facing surface such as resistance to abrasion, and the second face includes features making it suitable to form an inner-facing surface such as a soft hand.

A type of high-modulus-low-shrinkage activated PET industrial yarn and preparing method thereof are disclosed. The preparing method is to manufacture filament from a modified polyester, which is the product of the esterification and the successive polycondensation reactions of evenly mixed terephthalic acid, ethylene glycol and tert-butyl branched heptanediol, through a series of processes composed of viscosity enhancing by solid state polycondensation, melting, metering, extruding, cooling, oiling, stretching, heat setting, relaxation heat-treating, oiling with activation oil, winding and pre-activation treatment. The relaxation heat-treating indicates passing the modified polyester yarns through a space with a certain temperature within 200-220° C. under a proper relaxation state; and the proper relaxation state means a 3.0-5.0% of overfeed for the winding. The improvement of activator efficiency by importing the tert-butyl branched diol into the polyester, together with the synergistic effect of heat setting temperature and high winding overfeed rate, will reduce the fiber thermal shrinkage.

The present invention relates to a composite sheet comprising a woven fabric consisting of liquid crystal polyester fiber in which one side or both sides of the woven fabric is coated with a coating material comprising a thermoplastic resin, wherein a tensile strength of the composite sheet in a warp direction of the woven fabric is 300 N/cm or more, and wherein a ratio of a mass of the thermoplastic resin to a mass of the woven fabric is 5 to 25% by mass.

A knitted textile having a first layer including a first yarn with a thermoplastic composition integrally formed with a second layer including a second yarn, the first yarn forming an array of knitted patterns defining voids through the first layer to the second layer. The first layer may be heat treated to form a film. Treatment of the first layer may change zonal and directional tensile properties of the knitted textile. The Poisson's ratio of the knitted textile may be greater than or equal to zero in a first axis and/or a second axis, before and/or after treatment. Articles of apparel, including articles of footwear and garments incorporating the knitted textile, and methods of forming the knitted textiles and articles are disclosed.

According to an aspect of the present invention there is provided a knitted textile. The knitted textile comprises a knitted textile sensor. The knitted textile sensor comprises an electrically conductive yarn and a plurality of stitches that form a defined sensing stitch pattern. The sensing stitch pattern comprises stitches selected from the group consisting of: jersey stitches; tuck stitches; and/or miss stitches; as well as any combination thereof. The sensing stitch pattern provides a measurable contact resistance that varies with a force applied to the textile. The knitted textile comprises a knitted support structure within which the knitted textile sensor is integrated. The knitted support structure comprises a plurality of stitches that form a defined support stitch pattern, the support stitch pattern comprising stitches selected from the group consisting of: jersey stitches; tuck stitches; and/or miss stitches; as well as any combination thereof. The support stitch pattern has a smaller percentage of tuck stitches than the sensing stitch pattern. The textile is configured to elongate and retract in the wale direction in a repeatable manner, even after multiple washing cycles. Also provided are a garment comprising the knitted textile structure and knitted textile sensor.

Disclosed is a bending-resistant nerve catheter and a preparation method and application thereof, and relates to the technical field of tissue engineering materials. The catheter of the present application includes an inner layer, a middle layer and an outer layer, and each layer uses raw materials of biodegradable polymers; among them, the inner layer includes a smooth surface inner layer, an oriented microchannel inner layer or a fibrous inner layer, the middle layer is a fibrous middle layer with crossing angles, the middle layer is prepared by entangling micron fibers with a certain angular arrangement, and the outer layer is made of randomly entangled polymer fibers and is tightly bonded to the middle layer.

Provided are an artificial hair fiber having a soft texture and appearance close to human hair, and being light in weight; and a head accessory including the artificial hair fiber. A polyamide fiber for artificial hair includes a resin composition that includes a polyamide resin as a primary component resin, and is a hollow fiber having a void in the cross-sectional center section, the void percentage of the polyamide fiber is 15-40%, the fiber specific gravity of the polyamide fiber is 0.80-1.10, and the bend rigidity of the polyamide fiber is 1.5×10.sup.−3 to 5.5×10.sup.−3 gf.Math.cm.sup.2/yarn.

The present invention relates to a thermoplastic elastomer yarn with improved unwinding, weaving and yarn shrinking property, and a manufacturing method thereof. According to the present invention, the thermoplastic elastomer yarn according to the present invention is excellent in improved unwinding, weaving and yarn shrinking property. Furthermore, the thermoplastic elastomer yarn according to the present invention is excellent in yarn shrinkage rate, unwinding, weaving, tensile strength and elongation rate to be adequate for manufacturing textile fabric and footwear in terms of physical properties.
