吸湿发热罗马布的染整工艺研究

Study of Dyeing and Finishing Process of Moisture-absorption and Heat-generating Ponte-de-roma

利用黏胶腈纶吸湿发热Softwarm纱和锦氨包芯纱织造罗马布,并进行染整加工处理。详细介绍了过水烘干、预定形、前处理、染色、成品定形等工艺,测试了整理后织物的白度、毛效、渗透性以及色牢度等指标。结果表明,针对坯布与成品规格相差较大,应先过水烘干;吸湿发热罗马布前处理过程中,应严格控制温度、时间、双氧水以及碱的用量;在活性染料染黏胶时,先低温预加碱,以防止高温时对锦纶的沾色;处理后织物白度、毛效、缩水率、耐洗色牢度等指标符合要求。

Abstraet：Ponte-de-roma was knitted by viscose-acrylic moisture-absorption and heat-generating softwarm yarn and polyamide-spandex core spun yarn, and it was treated by dyeing and finishing process. Rinsing and drying, presetting, pretreatment, dyeing, setting and so on were introduced in detail, and the indices of whiteness, capil- lary effect, permeability and color fastness were tested. The results show that in consideration of the great difference between gray fabric and finished product standards, it should be rinsing and drying; it should strictly control temperature, time and the dosage of hydrogen peroxide and alkali in the pretreatment of moisture-absorption and heatgenerating ponte-de-roma; it should add alkali at low temperature in order to prevent polyamide staining at high temperature when dyeing viscose by reactive dyes; whiteness, capillary effect, shrinkage rate, and color fastness to washing of fabric after treatment meet the requirements.
