Embodiment Construction

[0010] Below in conjunction with the technological process that the present invention adopts, technical method of the present invention is described further:

[0011] Leftovers→screening ingredients→strike carding→recycling colored cotton fibers→matching cotton for color matching→spinning colored yarn→sizing and dyeing color matching→weaving→finishing→finished denim.

[0012] The screening ingredients in the above process are classified according to the fiber material and color of the scraps, so as to ensure the color stability and cotton fiber content of the dyed yarn spun in the subsequent process.

[0013] Most varieties of denim fabrics adopt the process of color registration, that is, first cover a layer of color on the warp yarn as the base color, and then dye the face color on the basis of the base color, so that some parts of the denim clothing will appear as face color after washing, and some The part is displayed as the base color, and some parts are displayed as the...

Abstract

The invention discloses a fiberizing, retexturing and recycling technology of fabric rags, in particular to a fiberizing, retexturing and recycling technology of denim fabric rags. In a treating and recycling process flow, color cotton fiber is directly produced without a bleaching process and spun after compounding cotton and mixing colors to produce dyed yarn in the same confirm color. The dyed yarn is made into chaine and is directly overdyed in a dying process to save a bottom color dying process, reduce the dye consumption, shorten production flows, save water and electricity costs, and take the favorable effects of saving energy and reducing consumption. Meanwhile, the invention can be used for producing overdyed denim fabrics of various color styles.

Description

technical field [0001] The invention relates to a technique for reusing fibrosis, regeneration, treatment and recycling of leftover scraps of cloth, in particular to a technology for fibrillation, regeneration, treatment and reuse of leftovers of cotton denim clothing fabrics. Background technique [0002] Denim clothing is the leading product in the entire clothing industry, and the demand for denim clothing in the world is increasing. During the manufacturing process of denim clothing, a lot of scraps of fabrics will be produced. Since the main component of cotton denim fabrics is cotton fiber, the existing technology of fibrillation treatment and recycling of scraps of denim fabrics adopts the following process: Scraps Scraps→screening→bleaching→drying→shock carding→reuse of white cotton fiber→mixing→spinning white yarn→sizing and dyeing→weaving→finishing→finished denim. [0003] Due to the above process, before the carding process, the original dyed lower corner scraps ...
