Abstract

The invention discloses a method for preparing an environmental-friendly waterproof warp knitted fabric and belongs to the technical field of fabrics. The method comprises the following steps: mixingplant ash, nano carbon powder, sodium hydroxide and water, and boiling; putting a ramie fiber and a nano carbon dioxide accelerant fiber into the boiled mixture, and continuously boiling; taking out the boiled fiber, washing with clean water, naturally drying in the air, and blending so as to obtain yarns; uniformly mixing chitosan, stearoyl sodium lactate, n-butyl alcohol, dodecafluoroheptyl methacrylate, sodium dodecyl benzene sulfonate and absolute ethyl alcohol in a reactor; soaking the blended yarns into the uniformly mixed solution, and performing magnetic stirring; and taking out the yarns, naturally drying in the air, dying in a drying machine, and finally performing warp knitting, thereby obtaining a fabric. The method disclosed by the invention is simple and feasible, process parameters are also relatively easy to control, and in addition, on-batch production can be achieved; the warp knitted fabric is high in waterproof property and is relatively high in softness, and in addition, original washing fastness and whiteness of the knitted fabric are not affected.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of an environment-friendly waterproof warp-knitted fabric. Background technique [0002] The name warp knitting comes from machine weaving, and the knitted fabric woven by warp knitting is called warp knitted fabric. The difference between warp knitting and weft knitting is that the loops it forms are arranged in the vertical direction or warp direction, and are formed by nesting adjacent yarns. The machine used for warp knitting looks somewhat like a loom, in that all the yarns are wound on warp beams, which are located behind and above the weaving zone, and all the yarns are fed into the weaving zone at the same time. During the nesting process, each yarn is controlled by an individual needle. However, the yarn guide bar controls the position of the yarn, and the needles used for each loop may vary. Needle control can be implemented using th...
