This invention relates to a partially elastic fabric and its weaving method, comprising a mesh fabric body. The mesh fabric body includes an embroidery layer, a textured layer, a functional yarn layer, and an elastic and reinforcing structural layer. It is woven using a warp knitting machine. The embroidery layer is formed on the uppermost layer of the fabric through a lateral shifting and pressing mechanism of the patterned yarn guide bars. The textured layer is formed through a double Jacquard guide bar loop-forming mechanism. The functional yarn layer is formed through a double ground guide bar loop-forming mechanism. The elastic and reinforcing structural layer is formed by a regular mesh structure woven through the ground guide bar weft insertion mechanism in conjunction with the loop-forming ground guide bar of the functional yarn layer. The weaving method of this invention produces a fabric with a strong structure and excellent physical properties such as wash fastness and rubbing fastness.

The invention provides a production method for one-bath one-step dyeing of a disperse / reactive dye, and belongs to the technical field of textile dyeing. According to the method, firstly, woven gray cloth is subjected to moisture regaining after doffing, pretreatment is conducted at a certain temperature and time, on the basis that a refining emulsifier and hydrogen peroxide are added, an oxygen bleaching agent is added into a pretreatment solution, oil and dirt in the spinning, weaving and other processes are directly removed, the permeability of the fabric and the adsorption capacity of the fabric to dye are improved, and the fabric has a good dyeing effect. The uniformity and color fastness of subsequent dyeing are improved, and the fabric is bright and pure in color and good in stability, has good coloring and leveling properties on the bright color, and is excellent in dyeing effect; after first acid adjustment, dyeing is carried out in a neutral dye bath by directly using dye liquor containing disperse dye and reactive dye at a certain temperature and for a certain time, the disperse dye does not need to be microencapsulated, the operation is simple and convenient, only clear water is needed for cleaning after dyeing, the dyeing time is shortened, the cleaning process is simplified, the water saving rate is high, and the purposes of saving energy and reducing consumption are achieved.

The invention discloses a dicarboximide monoazo disperse dye as well as a preparation method and application thereof, and relates to the technical field of azo disperse dyes, the structural general formula of the dicarboximide monoazo disperse dye is as shown in a formula 1 or a formula 2: # imgabs0. The dicarboximide monoazo disperse dye synthesized by the invention is applied to hydrophobic fiber dyeing, especially polyester fibers, and the dye has a good application prospect. The light-resistant, heat-migration-resistant, water-soaking-resistant, perspiration-resistant, color-fastness to washing and good fastness to rubbing are shown by the light-resistant, heat-migration-resistant, water-soaking-resistant, sweat-resistant, color-fastness to washing and good fastness to rubbing.

The invention provides an acid dye composition, an acid dye and a preparation method and application thereof. The acid dye composition comprises the following components: a component A, a component B and a component C, wherein the component A is C.I. Acid red 414; the component B is selected from one or two of C.I. Acid red 279 and C.I. Acid red 315, and the component C is one or two of C.I. Acid red 279 and C.I. Acid red 315. When the acid dye composition and the acid dye are used for dyeing wool, chinlon and blended fabrics thereof, the acid dye composition and the acid dye have good lifting power and compatibility and also have excellent washing fastness, rubbing fastness and perspiration fastness.

The invention discloses a method for preparing a concave-convex striped sofa fabric based on shrinkage yarn, and belongs to the technical field of functional textiles and post-finishing. The invention uses low-shrinkage polyester as warp yarn, high-shrinkage polyester and low-shrinkage polyester chenille as weft yarns respectively, and divides the low-shrinkage polyester into two groups. The first group of low-shrinkage polyester and high-shrinkage polyester are woven into a plain weave; the low-shrinkage polyester and low-shrinkage polyester chenille are woven into a 2 / 2 weft weight plain weave; the second group of low-shrinkage polyester and a high-shrinkage polyester are not involved in weaving when interlaced; the second group of low-shrinkage polyester and low-shrinkage polyester chenille are woven into a 2 / 4 twill; thereby forming a concave-convex striped sofa fabric. Afterwards, the concave-convex striped sofa fabric of the invention is post-finished. The concave-convex striped sofa fabric after finishing in the invention has permanent convex patterns, which can give the fabric a unique velvety feel and gloss.

An ink for ink-jet textile printing, the ink including a pigment, resin emulsion particles, an oxazoline-group-containing compound, and an aqueous medium, in which the resin emulsion particles have an average particle diameter of 150 nm or larger, a content of the resin emulsion particles is 10 to 20 mass% with respect to 100 mass% of the ink for ink-jet textile printing, and a content of the oxazoline-group-containing compound is contained in an amount of 0.5 to 10 mass% with respect to 100 mass% of the resin emulsion particles.

The invention belongs to the technical field of fabric dyeing, and provides an azo dye for a PET superfine fiber PU resin suede fabric, and a preparation method and a deep dyeing method thereof. The method comprises the following steps: preparing a diazonium salt solution from a diazonium component, dissolving a coupling component in water and hydrochloric acid or concentrated sulfuric acid, and cooling in an ice bath to obtain a cooling liquid; dropwise adding the diazonium salt solution into the cooling liquid, keeping the ice bath reaction after dropwise adding, removing the ice bath, and continuing the reaction to obtain the azo dye. According to the azo dye molecular structure model, hydroxyl groups are contained at the molecular ends, a large number of hydrogen bonds can be formed among the azo dye molecular structure model, PET superfine fibers and PU resin besides intermolecular force, the molecular structure is monoazo disperse dye, the structure is simple, the size is small, a fiber amorphous area can contain a large number of dye molecules, and the dye molecules can be used for dyeing the PET superfine fibers and the PU resin. The adsorption saturation value is high, the bonding capability is strong, and ideal deep dyeing property, rubbing fastness and thermal migration resistance are endowed.
