An artificial blood vessel and a method for preparing the same are disclosed. The method includes: weaving warp yarns and weft yarns to form interlaced first and second weaves, both weaves extend along a weft direction and alternate to obtain a composite fabric; and successively corrugating and thermal-setting the composite fabric to obtain the artificial blood vessel. In the composite structure of the artificial blood vessel with the alternating the first and second weaves formed by the warp and weft yarns, a softness degree of the first weave is lower than that of the second weave. As a result, combining stiffness of the first weave with softness of the second weave, this composite structure ensures both low permeability and increased softness of the fabric. Therefore, it is improved to a certain extent over the conventional woven artificial blood vessels and is easier to handle and suture.

The invention addresses the problem of providing a water-repellent cloth that is excellent in water repellency as well as stretchability and also a textile product using the water-repellent cloth. A means for resolution is a water-repellent cloth given water repellent processing, and the cloth is configured to include a composite yarn containing a stretch fiber and an ultrafine fiber having a single fiber fineness of 1 dtex or less.

A polyamide multifilament has a total fineness of 4.0-6.0 dtex, a single yarn fineness of 1.2 dtex or below, a strength-elongation product of 9.1 or above, and an elongation degree of 40-50%. A polyamide fiber has a small total fineness and single fiber fineness while having a high strength-elongation product and exhibiting a low unevenness (U%) in the longitudinal direction. Stockings exhibit an excellent higher-order process passability and productivity and exhibit an excellent softness, durability, and transparent feel and a fabric exhibits an excellent softness and durability.

The process of forming a blowable flexible innerduct contains the steps of forming an inner innerduct structure comprising at least one inner longitudinal chamber, where the at least one inner longitudinal chamber comprises an inflatable tube and forming a textile. Concurrently forming an outer innerduct structure from the textile having at least one outer longitudinal chamber and inserting at least one inner longitudinal chamber into at least one of the outer longitudinal chambers. The inflatable tube has a wall thickness of less than about 0.5 mm. The inner longitudinal chamber alone has an air permeability of less than about 1 cfm, outer longitudinal textile chamber alone has an air permeability of greater than about 100 cfm, and the outer and inner longitudinal textile chambers together have an air permeability of less than about 1 cfm.

Provided is a woven fabric which is suitable for use as a covering fabric for down garments, down jackets, bedclothes, sleeping bags, etc. The woven fabric is lightweight and thin, has a high tear strength, and can retain low air permeability even after laundering. The woven fabric is constituted of synthetic multifilament yarns. The woven fabric is characterized in that at least one side thereof has been calendered and the monofilaments in at least part of the synthetic multifilament yarns have been thereby compressed in a stacked state. The woven fabric is further characterized in that the monofilaments are fibers having an unusual cross-section, the degree of unusualness of the cross section as determined before calendering being 2.0-6.0, that the synthetic multifilament yarns have a fineness of 7-44 dtex, and that the woven fabric has a cover factor of 1,300-2,200.

The invention also relates to a method of manufacturing such masonry reinforcement structure (100) and to a roll comprising such a masonry reinforcement structure(100). The invention further relates to masonry reinforced with such masonry reinforcement structure (100) and to a method to apply such masonry reinforcement structure(100).

A fabric construct consists of a woven fabric of weft and warp yarns, and the fabric has an area defined by plurality of zones consisting of at least one zone of a first zone type, optionally, at least one zone of a second zone type; and at least one zone of a third zone type. The third zone is a transition zone disposed adjacent the first and/or second zones. All the zones are formed in a unitary woven construct, with adjacent zones seamlessly joined together. The transition zone includes a plurality of bands of sets of weft and/or warp yarns that collectively provide a progressive transition for an attribute of the first zone type through at least the transition zone and to the second zone type, if present. The fabric construct may be used in various end products and is particularly suited for use in apparel applications.

A flame resistant woven fabric has a thickness of 0.08 mm or more in accordance with the method of JIS L 1096-A (2010) and including warps and wefts, the warp and the weft each comprising: a non-melting fiber A having a high-temperature shrinkage rate of 3% or less; and a thermoplastic fiber B having an LOI value of 25 or more in accordance with JIS K 7201-2 (2007) and having a melting point lower than the ignition temperature of the non-melting fiber A; wherein the warp and the weft each have a fracture elongation of 5% or more; and wherein, in the projection area of the weave repeat of the flame resistant woven fabric, the area ratio of the non-melting fiber A is 10% or more and the area ratio of the thermoplastic fiber B is 5% or more.
