A method of printing and processing a fabric having first material yarns forming a technical front, and second material yarns forming a technical back, first and second material yarns being held together by a ground; carding and polishing the technical front to increase the permeability of the fabric; printing an image on the technical front of the fabric, so that ink from the printing process penetrates to the ground of the fabric; brushing and napping the technical back, after the printing process, so that ink from the technical front is pulled through the ground to the technical back, so that a mirror image of the image from the technical front is formed on the technical back.

A damage process for a textile product may include, but is not limited to, irradiating a laser beam onto a surface region of a textile product which is dyed, to burn the surface region, exposing the textile product to an ozone gas; and agitating the textile product together with at least one of: pieces of one or more solid materials having uneven surfaces and one or more abrasives of artificial fibers to allow the surface region to be shaved by the at least one of: the pieces of one or more solid materials and the one or more abrasives of artificial fibers. One or more subsequent processes can be carried out, without dipping the textile product into water or a liquid of chemicals, after agitating the textile product and until softening the textile product.

A welded yarn may have a cross section about a plane that is perpendicular to the longitudinal axis of the welded yarn wherein the cross-sectional area is comprised of two or more distinct portions, wherein the degree of welding in each portion is different, which may also result in different fiber volume ratios compared to raw yarn substrates.

Provided is a down-proof woven fabric which is highly effective to prevent leakage of down from a seam of a product, even having a low cover factor, the woven fabric containing a single yarn having a convex portion and a concave portion in a cross section, in which an air permeability is 0.1 cm.sup.3/cm.sup.2.Math.s or more and 2.0 cm.sup.3/cm.sup.2.Math.s or less; a total fineness is 5 dtex or more and 80 dtex or less; a total cover factor of a warp and a weft is 1500 or more and 2200 or less; a hole is formed in the woven fabric with a sewing machine needle having a cross-sectional diameter (thickness of a main body of the sewing machine needle) of 1.00 mm, and in an area having a radius of 1.5 mm about the hole, a total number of warps and wefts that are displaced by 0.08 mm or more with the sewing machine needle is 3 or less at 15 minutes after the sewing machine needle is pulled out from the woven fabric; and the following characteristics: (i) a fitting ratio of single yarns is 10% or more and 80% or less (ii) a laminating rate of the single yarn is 0.4 or more and 3.0 or less (iii) a number of convex portions of the single yarn is 2 or more and 12 or less (iv) the single yarn has a modification degree of 1.2 or more and 3.0 or less (v) a concave portion of the single yarn has a depth of 0.6 m or more and 8 m or less

CF=CF.sub.T+CF.sub.W where CF represents the total cover factor of the warp and the weft; CF.sub.T represents a cover factor of the warp; and CF.sub.W represents the cover factor of the weft.

The present invention provides a production process characterized in that a false twisting process is added between a spinning process and a winding process so that yarn slivers undergo excessive pre-torsion in an axial direction and twists which are same in quantity but different in twisting direction are generated on the yarn slivers. Absorption of glucose-containing sulfur dyestuff is performed in a dyeing process. An ammonia removal process is performed in a high-temperature and high-pressure tank so that residual ammonia in a fabric is evaporated. The evaporated ammonia is collected and then fed back to a mercerizing process for continuous use. The present invention also provides a production line including a spinning unit having a false twisting device, a dyeing unit configured to realize the dyeing process, and a liquid ammonia finishing unit consisting of a fabric mercerizing device, an ammonia removal device, an ammonia recycling device and a controller.

Vacuum printing a fabric involves forming a fabric having a top face and a bottom face and placing a barrier layer below the top face. A plurality of holes is established in the barrier layer, and dye is applied to at least a portion of the top face of the fabric. Vacuum applied to the bottom face pulls the dye through the fabric and the plurality of holes in the barrier layer.
