Abstract

The invention discloses a processing method of ultra-black imitation cotton silk, which comprises the following steps: carrying out esterification reaction on phthalic acid, ethylene glycol and isophthalic acid to obtain a mixture A; adding an antioxidant, a delustering agent, color master batches and an antibacterial agent into the mixture A to obtain modified polyester chips; wherein the color master batch is prepared from the following raw materials in percentage by weight: 0.4 to 5.8 percent of carbon black and 94.2 to 99.6 percent of polyester chips; the modified polyester slices are dried through a rotary drum and then extruded through double screws for melt spinning, and the super-black cotton-like silk is obtained.

Description

technical field [0001] The invention relates to the technical field of fiber preparation, in particular to an ultra-black imitation cotton silk and a processing method thereof. Background technique [0002] Super-imitation cotton products are not only similar to cotton fabrics in terms of fiber surface shape and fabric design style, but more importantly, their fabric characteristics and functions are cotton-like and super-cotton, and have high-quality dynamic moisture comfort performance. Super imitation cotton can well make up for the defects of cotton fibers, and use the characteristics of polyester to make up for the shortage of fibers, and the fabric made has improved durability. Most of the existing ultra-black imitation cotton silks are printed and dyed black on the polyester fiber by printing and dyeing processing to achieve the black effect, but the color fastness is not good. Contents of the invention [0003] In view of the above problems, the invention provides...
