Processing technology and processing device of functional composite knitted fabric

Abstract

The invention discloses a processing technology and a processing device of a functional composite knitted fabric, and relates to the technical field of textile. The processing device comprises a box body; a driving cavity and a spray dyeing cavity are arranged in the box body; a rotatable roller is arranged in the spray dyeing cavity; two groups of spiral grooves for wrapping cloth are formed in the circumferential surface of the roller in a circumferential array, and the spiral grooves are wrapped with the fabric; rotating supports are fixedly connected to the two ends of the roller; reel sets are arranged on the rotating supports; the fabric is led out through the reel set on the rotating support at one end and then connected to the reel set on the rotating support at the other end through the roller, and driving assemblies are arranged on the rotating supports to drive the reel sets to rotate; a plurality of thread nozzles are arranged on the two radial sides of the roller; the thread nozzles can be adjusted at any angle on an angle adjusting assembly; fabric is wound and wrapped on the spiral grooves of the roller during dyeing, the fabric is fed at a constant speed along the spiral grooves through rolling autorotation and reel rotation, and the fabric is kept in a flat state; and meanwhile, fabric deformation caused by stretching and straightening of the fabric is reduced, and the dyeing quality is improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a processing technology of functional composite knitted fabric and a processing device thereof. Background technique [0002] Knitted fabrics are fabrics formed by bending yarns into loops with knitting needles and interlocking them. The difference between knitted fabrics and woven fabrics is the shape of the yarn in the fabric. Knitting is divided into weft knitting and warp knitting. Knitting fabrics are widely used in clothing fabrics, linings, home textiles and other products, and are loved by consumers. [0003] The main disadvantage of weft-knitted fabrics is that they are easy to fall off. China's "Knitting Industry" 2017 No. 5 disclosed a development technology for weft-knitted fabrics that prevent falling off. Modal fibers and low-temperature meltable spandex are used. The setting temperature makes the spandex micro-melt so that the fabric coils do not fal...

Problems solved by technology

[0003] The main disadvantage of weft-knitted fabrics is that they are easy to fall off. China's "Knitting Industry" 2017 No. 5 disclosed a development technology for weft-knitted fabrics that prevent falling off. Modal fibers and low-temperature meltable spandex are used. The setting temperature makes the spandex micro-melt so that the fabric coils do not fall apart, and it is used in underwear design, so that the finished fabric can be cut freely, which solves the unfavorable factors of loose weft-knitted fabrics, easy to fall off, and easy to curl. The feel of the fabric is softer and more breathable than warp-knitted non-marking fabric, and it is more comfortable and beautiful to wear. However, the dyeing and finishing process in the later stage is too complicated, which seriously affects the processing efficiency. At the same time, the processing process requires a lot of manpower, so the production cost is increased. Therefore, We propose a processing technology and processing device for functional composite knitted fabrics
