Herein, R.sub.11, X.sub.1, X.sub.2, X.sub.31, X.sub.41 and n are defined in the specification. In addition, a method for dying fibers using the aforesaid reactive black dye composition is also disclosed.

A copolymer composition is disclosed with advantages for textile fibers, yarns, blended yarns, fabrics, and garments. The composition includes polyester copolymer, between about 4.5 and 5.5 percent adipic acid based on the amount of copolymer, between about 630 and 770 parts per million (ppm) of pentaerythritol based on the amount of copolymer, and between about 3.4 and 4.2 percent polyethylene glycol based on the amount of copolymer.

This invention relates to a Denim protective fabric, with fire-retardant properties, and the process of dyeing the warp with indigo blue dye on a mixture of cellulosic and synthetic fibers, in order to obtain a permanently fire-retardant fabric, resistant to flame, heat, breaking, tearing, cutting and abrasion by impact. The resulting fabric is also antistatic and can be considered as a protective fabric like fire-retardant Denim and also a multi-risk fabric. The indigo blue dye is applied on a mixture of cellulosic and synthetic fibers with permanently fire-retardant properties such as fire-retardant viscose, fire-retardant modal, modacrylic, polyacrylate, polyamide, polyester, antistatic carbon, para-aramid, meta-aramid, polyamide-imide, polyethylene, PBI, with the aim of obtaining an authentic Denim jeans fabric, with the characteristics of the tincture based on indigo blue dye that loses its color on rubbing, with use and washing.

There are described a bielastic fabric comprising biopolyamide yarn and elastane yarn, having excellent elastic properties and high dimensional stability, and a cost-effective, efficient process for obtaining it.

A method for manufacturing a foamed fabric includes providing a fabric which includes at least one layer including a plurality of first foamable filaments made from a first foamable polymeric material, infusing the fabric with a supercritical fluid in a pressurized vessel, subjecting the infused fabric to a depressurizing process to permit the at least one layer to undergo an initial stage of foaming so as to obtain a pre-foamed fabric, placing the pre-foamed fabric in a mold cavity, and heating the mold cavity to obtain a molded foamed fabric.

A process for preparing a skin-like flexible coating on a textile is described comprising preparing an Opuntia ficus-indica powder; creating a homogeneous mixture by mixing liquid polyurethane, pigments and additives; reducing the rate of mixing and adding the Opuntia ficus-indica powder to the homogeneous mixture; using a formulation based on the polyurethane and Opuntia ficus-indica homogeneous mixture as a skin-like flexible coating on the textile.

Disclosed herein are implementations of a weighted fabric and a method of construction thereof. The method for constructing the weighted fabric includes loading a first yarn on a cylinder of a double-knit circular knit machine. The method includes loading the first yarn on a dial of the double-knit circular knit machine. The method includes loading a second yarn on the dial of the double-knit circular knit machine. The method includes knitting the first yarn and the second yarn to construct the weighted fabric. The first yarn may be knitted at a first feed rate. The second yarn may be knitted at a second feed rate. The first feed rate may be greater than the second feed rate. The method may include dyeing the weighted fabric. The method may include framing the weighted fabric.

A textile material comprises a plurality of yarns, the yarns containing an intimate blend of dyed polyphenylene sulfide fibers and cellulosic fibers. The dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing textile materials containing polyphenylene sulfide fibers comprises the steps of (a) providing a textile material comprising yarns which contain an intimate blend of polyphenylene sulfide fibers and cellulosic fibers, (b) providing a dye liquor comprising a liquid medium and a disperse dye, (c) applying the dye liquor to the textile material, (d) heating the textile material under ambient atmosphere to a temperature sufficient to evaporate substantially all of the liquid medium from the textile material, and (e) heating the textile material under ambient atmosphere to a temperature of about 180? C. or more to fix the disperse dye to the polyphenylene sulfide fibers.
