The present invention refers to a red-dyeing acid dye mixture comprising a dye of the formula (I) ##STR00001##
and at least one dye of the formula (II) ##STR00002##
a process for its manufacturing and a process for dyeing and printing of natural or synthetic polyamide fiber material in which it used.

In one aspect, a composition for treating fibers comprises an acidic aqueous or aqueous-based continuous phase and a liquid repellent phase comprising a dendrimer component and/or non-dendrimer alkyl urethane. The treatment composition, for example, can have pH of 2.5 to 6.5. In some embodiments, carboxylic acid is employed in the treatment composition for providing the acidic character of the aqueous or aqueous-based continuous phase. Moreover, the treatment composition can further comprise at least one of an acid stain resist component and soil release component. In some embodiments, fibers treated with compositions described herein exhibit ionic character.

An acid dye composition for dyeing nylon textiles is disclosed, which comprises: an acid dye; and a water soluble Ca.sup.2+ compound, wherein, on the basis of a total weight of the acid dye as 100 parts by weight, a content of the water soluble Ca.sup.2+ compound is ranged from 0.1 parts by weight to 50 parts by weight. In addition, a use of the aforesaid acid dye composition and a method using the same for dyeing nylon textiles are also disclosed.

A method of forming an active agent infused linear material includes passing a substantially linear polymeric substrate through a linear substrate infusion chamber in a first direction, flowing a liquid infusion solution through the linear substrate infusion chamber in a second direction, and contacting the linear substrate with the liquid infusion solution at an infusion temperature and for an infusion time effective to infuse the one or more active molecules into or onto a surface of the linear substrate, thereby forming an active agent infused linear material. The liquid infusion solution includes one or more active molecules. The second direction is substantially opposite or substantially parallel to the first direction. A linear substrate infusion system and a polymeric linear substrate are also disclosed.

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
