The dyeing and finishing technology of zein fiber/cotton blended fabric
?
Technical field
The present invention relates to fabric dyeing and finishing process, relate in particular to a kind of dyeing and finishing processing method of zein fiber/cotton blended fabric.
Background technology
Zein fiber is a kind of green fiber being widely used now, and in fact taking the starch such as corn, wheat as raw material, first changes into lactic acid again through polymerization through fermentation, and the acid fiber by polylactic that the techniques such as melt spinning are made, is commonly referred to as zein fiber.This fiber has biodegradability, can be transformed into carbon dioxide and the water of environmentally safe, and carbon dioxide and water can be transformed into starch under photosynthesis, thereby realize recycle after discarding.
Zein fiber is softly smooth, and intensity is large, and moisture absorption is ventilative, and the product of processing has gloss as silk and comfortable skin sense of touch and feel, and drapability is good, good heat resistance and anti-ultraviolet function, and wearability is good.Zein fiber is suitable for disperse dyeing, but because fibrous and structure are different from polyster fibre, dyeability difference is very large, and on the whole, its dyeing temperature is low, and difficulty is dyed dark color, and fastness is poor, more responsive to alkali and temperature.
What at present the dyeing of zein fiber is used is low temperature DISPERSE DYES, and temperature generally, 200 DEG C of left and right, still can have damage to zein fiber, but low its dyeing of temperature just can not realize again.
Summary of the invention
Goal of the invention: the object of the invention is in order to solve the deficiencies in the prior art, a kind of dyeing and finishing processing method that zein fiber is damaged to little, dyeing and finishing is effective zein fiber/cotton blended fabric is provided.
Technical scheme: a kind of dyeing and finishing processing method of zein fiber/cotton blended fabric, wherein fabric is to adopt zein fiber and cotton fiber blending to weave to form, and the percentage by weight of two kinds of fibre fractionations is, 50% zein fiber, 50% cotton fiber, the principal length scope of the zein fiber of employing is 30-40mm;
Dyeing and finishing processing method mainly comprises to be weaved, and------bleaching---dyeing---arranges afterwards in kiering;
