The invention relates to a process for manufacturing a multilayer knitted textile by heating a multi-layer knitted textile in the presence of one or more dye compounds, wherein the multilayer knitted textile comprises a fabric outer layer and a fabric inner layer, wherein the fabric outer layer is knit from a first yarn containing a combination of modacrylic fibers and cotton fibers, wherein the fabric inner layer is knit from a second yarn made from 50-90% HBA/HNA filaments, wherein the heating shrinks the outer layer from about 5 to 25% in length, width, or both.

A cuttable knit fabric of the present invention may comprise: a knitted fabric woven with a single yarn; a first reinforcing part disposed to correspond to a central portion on the lower surface of the knitted fabric; and a second reinforcing part disposed to surround the periphery of the first reinforcing part on the lower surface of the knitted fabric. A first reinforcing fiber of the first reinforcing part and a first reinforcing fiber of the second reinforcing part may be formed by tangling with the yam of the knitted fabric. The first reinforcing part and the second reinforcing part may be formed of different materials. The first reinforcing part and the second reinforcing part may have different tensile strengths.

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.

A non-coated base fabric for an airbag is made of a polyamide fiber, wherein a CV value of the dynamic air permeability by the ASTM D6476 method is 6.0% or less, a CV value of the air permeability at a differential pressure of 500 Pa by the ASTM D3886 method is 10.0% or less, and a CV value of the air permeability at a differential pressure of 20 KPa is 10.0% or less, which are measured every 20 cm in a weft direction of the base fabric.
