Production method of warp-knitted Raschel blanket

Abstract

The invention discloses a production method of a warp-knitted Raschel blanket. The production method of the warp-knitted Raschel blanket comprises the technological processes of raw material selection, weaving, sectioning, inspecting, high-temperature shaping, gray fabric brushing, grey cloth ironing and glossing, printing, permeating, drying and color fixing, washing, shaping and drying, brushing, ironing and glossing, ironing and shearing, after-finishing, cloth cutting, edge covering inspection, packaging, warehousing and the like, can achieve the effect of rapid brushing of the fiber twistof the front rough surface of grey cloth, and has the advantages of ironing gloss, exquisite hand feeling, smooth and flat rough surface, no wrinkles, rapid production and high efficiency, so that manual work is greatly reduced; air blowing cooling is conducted after the last time of ironing and glossing of the grey cloth is finished, so that the temperature reaches the normal temperature duringcropping, the consistency of the rough surface is guaranteed, and disordered wools and creases are avoided; and meanwhile, an oil fume purifier is additionally arranged to recover oil fume, so that oil fume emission is reduced, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of producing Raschel blankets, in particular to a production method of warp-knitted Raschel blankets. Background technique [0002] Warp-knitted Raschel polyester blankets were transformed from warp-knitted Raschel acrylic blankets after 2008. In the past, acrylic fibers were used to make Raschel blankets, and no pre-finishing was required; after the weaving was completed, the white cloth was shaped. Direct printing, but after replacing acrylic with polyester, it is necessary to brush and iron the white cloth first after the white cloth is shaped, brush the wool of the polyester gray cloth, and print after the luster is ironed, and the final quality of the warp-knitted polyester Raschel blanket is It is determined by the quality of the pre-finishing and the finishing of the rough surface; whoever does the pre-finishing well will have a better final quality of the polyester blanket. Therefore, in recent years...

In the past, acrylic fibers were used to make Raschel blankets, and no pre-finishing was required; after the weaving was completed, the white cloth was shaped. Direct printing, but after replacing acrylic with polyester, it is necessary to brush and iron the white cloth first after the white cloth is shaped, brush the wool of the polyester gray cloth, and then print after the gloss is ironed, and the final quality of the warp-knitted polyester Raschel blanket is It is determined by the quality of the pre-finishing and the finishing of the rough surface; whoever does the pre-finishing well will have a better final quality of the polyester blanket. Therefore, in recent years, all blanket factories have invested in equipment and technology to study the pre-finishing process. , and as the cost of labor is getting higher and higher, how to save personnel and improve equipment automation has become the top priority of manufacturers
