摘要

冷轧堆 工艺是在室温下的加工过程，由于冷轧堆加工技术具有投资成本低，能耗、

水耗少，柔性 生产率高、

工艺适应性强，

织物强度损失小等众多优点，

目前在棉织物染整

加工中广泛应用于前处理、染色、印花及后整理。冷 轧堆的前处理工艺主要包括退浆、

煮

练和漂白，

将汽蒸堆置改为室温堆置，

极大地节约了能源和设备的投资，

< br>而且适用于小批

冷轧堆染色工艺 流程短，

设备简单，

对环境污染小，因不经烘干

Abstract

Cold pad-batch process at room temperature process, because the cold pad-batch process

technology has the advantages of low investment cost, energy consumption, water consumption

and

Cold

pad-batch

pretreatment

process mainly includes desizing, scouring and bleaching, the steam is changed into a stack of

stack room temperature, can greatly save energy and the equipment investment, and is suitable

for small batch and many varieties of processing requirements. Cold pad-batch dyeing of short

process flow, simple equipment, little pollution to the environment, because without baking and

steaming, thereby saving energy, having small bath ratio, high rate of color ( the color fixing

rate than conventional rolling braizing method to improve 15-25% ), there is no dye migration

and

other

characteristics,

According

to

the

report,

the

European

dyeing with reactive dyes have 1 / 3 is the use of cold pad- batch dyeing processing technology.

In recent years, China's increasing energy costs and improving quality of new varieties available,

dyes, printing and dyeing mill by cold pad-batch dyeing technology is more and more prevalent.

.

整个过程虽然是半连续的，但由于准备 工作都在上机前完成，故生产效率非常

高。

上染、固色 都在室温下完成，水洗虽然需要加热，但由于冷染固色率高，水解

染料

少，清洗容易，相比需中间烘燥汽蒸的轧染，大大节约了水、汽能源，缓解了污 水

脱色压力。
