Sizing-dyeing method and sizing-dyeing equipment assembly for color yarn production by paint spraying

Abstract

The invention discloses a sizing-dyeing method and a sizing-dyeing equipment assembly for color yarn production by paint spraying. The sizing-dyeing equipment assembly comprises a multi-unit constant-tension winding and unwinding system, an ultrasonic cation modification system, a drying system, a plasma treatment system, a paint spraying system, an infrared constant-temperature pretreatment and shortened wet steaming system, a fixation drying system, a sizing system, an intelligent constant-tension yarn storage rack, a lease system and a winding system. By adoption of the paint spraying system for paint spraying of yarns, a traditional dip dyeing procedure is replaced, pollution is avoided, residue of paints in dip dyeing bath is avoided, sewage discharging burden after dyeing is relieved, total dyeing cost is reduced, and ecological environment is improved. Colorful patterns are formed on the yarns to meet market demands and customer aesthetic variations, and the technical problem of pattern diversification on a current dyeing market is solved.

Description

technical field [0001] The invention belongs to the technical field of sizing and dyeing, and in particular relates to a sizing and dyeing equipment assembly for producing colored yarns by spraying paint and a sizing and dyeing method thereof. Background technique [0002] Environmental protection and ecological awareness make people more and more demanding on textiles known as the second skin of the human body. Therefore, in the whole process of textile processing, people pursue environmental protection, ecology, simple process, low investment, less equipment, and energy saving. , No washing is required, and no or less waste liquid discharge is required to protect the environment. [0003] Pigment printing and dyeing technology can basically meet the above requirements. With the rapid development of high technology and the development and research of new additives, the paint printing and dyeing technology has reached a relatively high level, which can basically meet the ch...

Problems solved by technology

However, in the application of this technology, the coating cannot effectively penetrate into the yarn fiber, which causes many serious technical and quality problems: First, the color fastness is poor, especially the rubbing fastness, which can only be produced for garment polishing 1. The dyed yarn required for washing; the second is poor dyeing core penetration, the surface of the yarn is dyed with color, but the inside is white, and the twist of the yarn is loose in the subsequent processing process to expose white spots; the third is the low dyeing rate, It is difficult to dye dark colors, the quality is unstable, and the adhesive sticks to the roller seriously

The method proposed in patent 201010580702.3 has been verified through actual verification and found that the color fastness cannot meet the needs of the market, and the general color fastness is not higher than level 3
