Problems solved by technology

However, due to the fibrillation of Lyocell staple fiber fabrics, the outer layer of the fibers is prone to breakage after being mechanically rubbed in a wet state, forming hairs with a length of about 1 to 4 microns, and even entangled into cotton in severe cases. grain
Therefore, Lyocell staple fiber fabrics are prone to fuzzing, pilling, and color changes during use, and the fabrics will harden in hot and humid environments, making clothes have a strong sense of obsolete

Abstract

The invention relates to green and environment-friendly fabric interwoven by Lyocell filament and staple fiber yarn and a preparing method of the green and environment-friendly fabric. Regarding the green and environment-friendly fabric interwoven by the Lyocell filament and the staple fiber yarn, the Lyocell filament serves as warp, cellulose fiber stable fiber yarn serves weft, and the green andenvironment-friendly fabric is processed through weaving. The preparing method of the green and environment-friendly fabric comprises the steps of 1, selecting Lyocell FDY (fully-drawn-yarn) and cellulose fiber stable fiber yarn as raw materials; 2, beaming the Lyocell filament; 3, sizing the Lyocell filament; 4, re-beaming the Lyocell filament; 5, leasing the Lyocell filament; 6, drafting and reeding the Lyocell filament; 7, weaving into the fabric. The fabric is high in degradability, and has excellent water absorption performance, draping and abrasive resistance, and is not prone to pilling, high in fastness and little in colored light change; the warp serves as the filament, the spinning process is omitted, the energy and labor are saved, the preparing cost is low, and the method is simple and suitable for industrialized production.

Description

technical field [0001] The invention relates to a fabric in the textile field and a preparation method thereof, in particular to a green and environment-friendly fabric interwoven with Lyocell filaments and spun yarns and a preparation method thereof. Background technique [0002] Lyocell fiber is based on planned planting forests, using a patented solvent method to prepare cellulose fibers. The solvent in its manufacturing process belongs to a closed cycle, and no waste water, waste gas and waste pollution will be generated during the manufacturing process. It is currently the safest and most environmentally friendly green fiber, so Lyocell's staple fiber fabrics have developed rapidly. However, due to the fibrillation of Lyocell staple fiber fabrics, the outer layer of the fibers is prone to breakage after being mechanically rubbed in a wet state, forming hairs with a length of about 1 to 4 microns, and even entangled into cotton in severe cases. grain. Therefore, Lyocel...
