Description
(1) technical field
The present invention relates to the assistant composition that a kind of textile dyeing and finishing processing is used, particularly relate to the processing of a kind of textile dyeing and finishing with, substitute the tasteless organic acid agent of the solid composition of acetate, its give various fiber textiles in the dyeing and finishing process, regulates pH value and in the benefit of alkaline agent.
(2) background technology
In the textile dyeing and finishing process, almost each operation all has the requirement of regulating pH or neutralization, and considers the security of textiles and the variation of coloured light, and inorganic acid is to adopt as sulfuric acid, hydrochloric acid etc., and traditional method is to use acetate.
Textile dyeing and finishing processing is main to divide four parts: scouring and bleaching, dyeing, stamp, back arrangement.As scouringing and bleaching of COTTON FABRIC, use sodium hydroxide and other matter, after finishing operation, must neutralize with acetate; Adopt dyestuffs such as reducing dye, REACTIVE DYES, SULPHUR DYES, azoic dyes insoluble azo dyes to dye during dyeing, all adopted alkaline agent (NaOH or soda ash) in the dyeing, before finishing dyeing, the alkali on the textiles must be neutralized, make the pH value of textiles reach neutral, stamp and finishing process also are like this.And chemical fibres such as terylene is knitted, polyamide fibre, acrylic fibers, polyvinyl, viscose glue also adopt NaOH or soda ash in the operation of scouringing and bleaching, and finish operation also will neutralize; Disperse dyeing of polyester, ACID DYES is dyed silk, hair, polyamide fibre and cation dyes and is dyed acrylic fibers etc. and all pH value will be transferred to and dye under the acid condition, all regulate with acetate at present, stamp under acid condition and back arrangement are also used acetate to carry out the pH value in a large number and are regulated.Acetate is used very wide in the textile dyeing and finishing process, textile dyeing and finishing processing is used a large amount of.
But during using, acetate has following shortcoming:
1, acetate is volatile acid, makes the pH value conditioning agent with it, can cause the volatilization pH value with acid to change, and cause the dyeing and finishing quality problem, particularly changes of shade.If make neutralizing acid with it because the volatility of acid, use hot bath may reduce in and efficient.
2, with in the acetate and when the caustic soda on the textiles, soda ash, form acetic acid sodium salt, if do not remove these sodium acetates, sodium acetate will cause the harder feel of textiles, and these salt residues produce reducine compound (as caustic soda) will or store for a long time in dried cloth heat treatment the time.
Jaundice and lower when storing fluorescence and add effect after white when producing this situation and will make dried cloth, and can influence the coloured light of dyeing back to the dyestuff of Acidity of Aikalinity sensitivity.
3, after the neutralization, the remnants of acetate clean relatively difficulty, must be through the cleaning more than 3 roads after adding acid.And in the operation of scouringing and bleaching and after need more the cleaning when contaminating.
4, neutralization back is cleaning dirty, because acetate all has penetrating odor, can cause peculiar smell before the weaving and influences sale, and particularly exporting textiles can not have peculiar smell.
If 5, acid does not have time enough to affact cellulose inside so just can not to neutralize fully, the salt (sodium acetate) that generates forms the more difficult infiltration in inside that buffering (sodium acetate one acetate buffer system) makes fiber with acetate in the outside of fiber, makes neutralization not exclusively on the contrary.
6, acetate is inflammable thing
7, acetate is liquid, and is corrosive liquids, dangerous goods, and transportation is inconvenient, easily is stained with human body skin in the use and causes safety problem, and its penetrating odor also has stimulation to the human respiratory tract.
8, use the acetate large usage quantity, cost is higher.
9, acetate freezes in the time of 16 ℃, uses inconvenient.
