Abstract
This invention discloses an enhancer to carry on alkali decrement processing for the polyester fiber fabric, which belongs to the area of textile dyeing and finishing technology. Its component and the quality percentage is: the polyethylene oxide's twin quaternary ammonium salt positive ion surface active agent from 20% to 40% is included, the non-ionic surface active agent from 2% to 10%,and the rest is water. As the twin quaternary ammonium salt positive ion surface active agent including the polyethylene oxide is used .On one hand, it raises the hydrolytic reaction speed. On the other hand, as a result of the polyethylene oxide base's existence, it brings more temperateness which the promoter action ordinary quaternary ammonium salt surface active agent brings, which enhances the decrement uniformity. At the same time, after the polyethylene oxide's twin quaternary ammonium salt positive ion surface agent and the fat mellow polyethylene oxide ether class non-ionic surface active agent duplicate matches, it has the synergism, which can reduce the surface tension even better, lye the promotion even seepage, cause the decrement processing to be more evener, and may modify fabric feel and the superficial function.
Description
Technical field
The present invention relates to a kind of textile finish, particularly a kind of dacron fabric is carried out the promoter of alkali decrement treatment, belong to the textile dyeing and finishing technical field.
Background technology
In recent years, the synthetic fiber industry development is swift and violent, and polyester fiber (terylene) is widely used in all kinds of textiless as the maximum synthetic fiber of output.Undressed dacron fabric exists feel at aspect of performance and more firmly, easily produces defectives such as aurora, in order to address the above problem, in dyeing and finishing processing, often polyester textile is carried out the alkali decrement treatment, is commonly referred to as " emulation silk " arrangement.The alkali decrement treatment is dacron fabric to be put into concentrated alkali solution chemical reaction takes place, alkali makes ester bond generation hydrolysis in the big molecule of polyester fiber, it is from fiber surface, gradually to internal penetration, make the fiber surface corrosion, organizational slack, the quality of fiber itself reduces thereupon, thereby makes polyester fiber obtain the soft feel as the real silk, soft gloss and good drapability.
In the alkali decrement processing of terylene, in order to promote the basic hydrolysis speed of fiber, improve the efficient of decrement processing, general method is to add base reduction promoter, base reduction promoter commonly used is a quaternary cationic surfactant, as cationic surfactant 1227 (dodecyl benzyl dimethyl ammonium chloride), cationic surfactant 1231 (DTAB), cationic surfactant 1631 (softex kw), cationic surfactant 1627 (cetalkonium chloride), antistatic additive SN (octadecyl dimethyl ethoxy ammonium nitrate) etc.As the dacron base reduction promoter, the basic hydrolysis of dacron is a kind of liquid-solid phase-transfer-catalyzed reactions with quaternary surfactant.Quaternary surfactant is joined in the alkaline bath of heat, the mechanism of its effect is: quaternary surfactant is adsorbed at first rapidly on the dacron surface, reduces fiber surface tension force; Secondly, anion in the quaternary ammonium salt molecule and the hydroxyl radical negative ion generation ion-exchange reactions of handling in bathing, hydroxyl radical negative ion in the body lotion shifts and is enriched in fiber surface, make hydroxyl radical negative ion that carbon atom in the carbonyl of band portion positive charge in more opportunity and the big molecule of easier attack fiber be arranged, cause the big molecular breakdown of fiber, thereby promoted hydrolysis.
The facilitation effect of promoter is relevant with the molecular structure of quaternary surfactant, and cationic surfactant is along with the growth of hydrocarbon chain increases in the absorption of fiber surface, and surface tension reduces big more, and is good more to the facilitation effect of alkali decrement; The big molecule affinity of quaternary ammonium ion and fiber is bigger, and the effective collision probability of ester bond is big more in the big molecule of quaternary ammonium salt and fiber, and catalytic capability is big more.Above-mentioned common quaternary cationic surfactant, polyester fiber alkali decrement treatment had fairly obvious facilitation, therefore, caused process to polyester fiber alkali decrement defective more rambunctious, the uniformity of decrement processing is relatively poor, and the strength loss of dacron fabric is bigger after the decrement treatment.
Continuous development along with fiber process technology and weaving technology, the fiber number of fiber reduces gradually, the kind of weaving face fabric is also more and more, in order to guarantee that the brute force after the polyester textile decrement treatment reaches the requirement of taking textiles, must improve alkali decrement processing uniformity, under the condition that obtains same reduction rate, the strength loss that how to reduce dacron fabric seems particularly important.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of and can effectively improve polyester fiber alkali decrement treatment speed, and improve the uniformity of alkali decrement treatment, reduce the base reduction promoter of fabric strength loss.
The technical solution used in the present invention is: a kind of dacron fabric alkali decrement processing promoter is provided, the constituent of this promoter and mass percent are: the duplex quaternary cationics 10～40% that contains polyoxyethylene groups, non-ionic surface active agent 2～10%, all the other are water; The described duplex quaternary cationics that contains polyoxyethylene groups is one or more the mixture with following structure:
In the formula: m=7～17; N=1～3; Y=2～6; X=Br or Cl.
Described non-ionic surface active agent is fatty alcohol-polyoxyethylene ether a kind of with following structure:
CH
3(CH
2)
p—O(CH
2CH

In the formula: p=7～17; Q=5～20.
Compared with prior art, the present invention has the following advantages:
(1) owing to adopted the duplex quaternary cationics that contains polyoxyethylene groups, its quaternary ammonium salt cationic can make the hydroxyl radical negative ion of handling in bathing shift and be enriched in fiber surface, make hydroxyl radical negative ion that carbon atom in the carbonyl of band portion positive charge in the big molecule of the also easier attack fiber of more opportunity be arranged, improve the speed of hydrolysis; Simultaneously, because the existence of polyoxyethylene groups, produces sterically hinderedly, make the gentleness of the more common quaternary surfactant of facilitation, improved the uniformity of decrement.
(2) adopt the duplex quaternary cationics and the fatty alcohol polyethenoxy ether class non-ionic surface active agent that contain polyoxyethylene groups to carry out composite preparation dacron fabric base reduction promoter, the duplex surfactant has higher surface-activity than common cation surfactant, and it is composite with non-ionic surface active agent, produce synergy, can better reduce surface tension, promote the uniformly penetrating of alkali lye, can make decrement treatment more even.
(3) add non-ionic surface active agent in the component insoluble substance that the processing bath may exist is had dispersion, reduce the deposition of insoluble matter, can improve feel and the surface property of handling fabric at fabric face.
