彩色墙衣装饰纱工艺设计

Process Design of Color Wall Coat Decorative Yarn

探讨以棉、木棉、再生涤纶及再用棉等低成本材料为主要原料生产彩色墙衣装饰纱的生产工艺要点。依据"特粗号数设计,大捻度配置,鲜艳色调搭配"的设计理念,选择粗纱成纱的工艺设计方案,在粗纱工序上通过设备改造拓展粗纱加捻和牵伸设计范围,加大粗纱捻度,缩小牵伸倍数,从而实现粗纱成纱的特粗号纺纱工艺;优化染色工艺,有效增加了染料助剂的匀染性和渗透性,同时保证了色白相配的AB纱效果。纺制出的彩色墙衣装饰纱抱合紧密,色彩鲜艳,符合墙衣装饰用纱的要求。认为:彩色墙衣装饰纱附加价值高,变废为宝,环保节能。

Production process points of producing color wall coat decorative yarn using lower cost material as main raw material like cotton, kapok, renewable polyester and renewable cotton were introduced. Roving spinning technology design project was selected base on the design concept of super thick count design, larger twist config- uration and bright color matching. Through equipment modification, the range of roving twisting and drafting de- sign were expanded. Roving twist was increased and draft was decreased. Super thick roving spinning technology was realized. Dyeing technology was optimized,leveling property and permeability of dyeing auxiliaries were in- creased. Appearance effect like AB yarn was ensured. Color wall coat decorative yarn which was spun has compact structure and vivid color. It is considered that color wall coat decorative yarn is higher value, energy saving and environmental protection.
