Description
Technical field
The present invention relates to textile auxiliary field.It is more particularly related to a kind of low temperature scouring agent, preparation method and
Its purposes.
Background technology
Cotton/wool-rich blended yarns have the plentiful feel and resilience of wool concurrently, and cotton hygroscopicity and snugness of fit, be one
Class has the fabric raw material of market prospects very much.The clothes that the fabric made with it is made are soft by the universal of consumer
Welcome.But in being handled before dyeing, traditional hair/cotton is under the high temperature conditions, to have used alkali, surfactant and dioxygen
Water, handles 60-90 minutes under 98-100 DEG C of high temperature, easily damages wool, causes yarn strength to lose big, production effect
The low fabric weight-loss ratio of rate is big, and the COD value consumed in substantial amounts of energy, waste water is very high, and process water consumption is big, high energy consumption, takes
It is long, not only aggravated sewage disposal burden but also textile had been damaged, and also high temperature can easily cause the diseases such as fine wrinkle, be a kind of
The processing technology of non-environmental protection,.In order to reduce the strength loss of velvet apple yarn, production efficiency is improved with weaving, it is concise using low temperature
Agent, at present, many producers are also in research low temperature pre-treatment auxiliary agent, because the reasons such as effect, cost price can not put into big production.
The content of the invention
First purpose of the present invention, is to overcome above mentioned problem that there is provided a kind of low temperature scouring agent, this low temperature scouring agent energy
Enough short processes flows that traditional high-alkali boiling and bleaching process of high temperature is improved to the few soda boiling drift unification of low temperature, so as to shorten technique
Time, production efficiency is improved, save the consumption of steam and electricity, and sewage quantity, environmental protection and economy can be mitigated.
Second object of the present invention, is to provide for a kind of preparation method of low temperature scouring agent.
Third object of the present invention, is to provide for a kind of low temperature scouring agent answering in cotton fabric category pre-treating technology
With.
In order to reach first mesh of the present invention, the technical solution used in the present invention is as follows：
A kind of low temperature scouring agent, it is characterised in that：The low temperature scouring agent is 15%~25% low by weight/mass percentage composition
Warm bleaching agent and weight/mass percentage composition constitute for 75%~85% low temperature oxygen bleaching activator,
Wherein, the low temperature bleaching agent is made up of the component of following parts by weight：
The low temperature oxygen bleaching activator is made up of the component of following parts by weight：
Preferably, the alkylolamides APEO is that the aliphatic acid that carbon number is 8~18 first passes through ethanol
Amine is condensed, then the product obtained by ethoxylation, and its ethoxy radix is 3~6.
Preferably, the chelated dispersants are selected from the acrylic acid maleic anhydride grafts that molecular weight is 1000~5000.
Preferably, the activator accelerator is one kind in N NMFs, urea, dicyandiamide.
Preferably, the one kind or combination of the alkaline agent in sodium carbonate, sodium hydroxide, sodium acid carbonate.
In order to reach second mesh of the present invention, the technical solution used in the present invention is as follows：
A kind of preparation method of low temperature scouring agent, using following steps：
S1：The preparation method of the low temperature bleaching agent：By alkaline pectase, butyl ricinoleate sodium sulphate, alkylolamides
APEO, proportioning of the organic silicon defoamer as described in claim 1 is put into reactor, is mixed evenly, is produced
Low temperature bleaching agent；
S2：The preparation method of the low temperature oxygen bleaching activator：By Cocoamidopropyl betaine, chelated dispersants, activation
Agent accelerator, alkaline agent, proportioning of the water as described in claim 1 is well mixed, and 15~30min of stirring at low speed produces low temperature oxygen bleaching
Activator；
S3：Product obtained by step S2 and step S3 is mixed evenly in proportion, that is, is re-dubbed low temperature scouring agent.
In order to reach the 3rd mesh of the present invention, the technical solution used in the present invention is as follows：
A kind of purposes of low temperature scouring agent, for the low temperature Scouring and bleaching process of fabric, is carried out according to the following steps：
S1：Bath raio is used for 1:10, at room temperature by fabric, 30% 3~5g/l of hydrogen peroxide, low temperature oxygen bleaching activator
0.5~1g/l is added in dye vat, is to slowly warm up to 40 DEG C and is entered to contaminate 10min, adds 1~2g/l of low temperature scouring agent；
S2：Arrange parameter, 65~80 DEG C, 40~60min of insulation operation are warming up to 2 DEG C/min；
S3：Then with 80 DEG C of 5~15min of hot water wash, cold water is cleaned, drying, that is, is made through locating before low temperature scouring agent low temperature
The fabric of reason.
Preferably, the fabric is cotton or its blend fabric.
The selection of the low temperature bleaching agent raw material of the present invention is to be directed to the composition of weaving yarn sizing agent and determine, alkaline pectase
The starch and deformation starch of fabric can be effectively removed, and it is biodegradable, it is environmentally safe；Oily wax in fabric by
Emulsification could be removed.Pass through the wetting action of surfactant butyl ricinoleate sodium sulphate, the adhesion of oily wax and fabric
Weaken, interface is gradually reduced, oily wax is split away off from fabric, be dispersed in superfine particulate in main experienced liquid.Due to oily wax
The contact surface increase of particulate and water, surface can increase, and be consistent unstable system, add the extremely strong nonionic table of emulsifying capacity
Face activating agent alkylolamides APEO, reduces surface tension, improves the permeability of alkali lye and the wetability of cotton fiber,
Oily wax particulate in scouring process is fully emulsified and increase its solubility in water to greatest extent, so as to improve positive reaction
Speed, reduces kiering temperature, greatly enhances kiering effect.Due to doing bleaching agent using surfactant, it is easy to produce big
Measure foam.Foam is excessive to be caused to waste and influence scouring result, and is returned fabric rinsing and brought difficulty.From low in formula
The surfactant butyl ricinoleate sodium sulphate of foam, while adding defoamer again, can reduce the production of foam.
The low temperature bleaching agent of the present invention coordinates low temperature oxygen bleaching activator to use, and can reduce routinely to move back to boil in technique largely using
Caustic soda consumption, while can also make pre-treating technology flow shorten, the high-temperature process time shorten, so that pre-treatment is greatly reduced
Cost, energy consumption, the water consume of processing.The organic compound such as N NMFs that the water solubility of addition is stronger can make surfactant
Solubility in water is greatly increased, and the chelating agent of addition with demineralized water, can give full play to the effect of surfactant.
The beneficial effects of the invention are as follows：
(1) low temperature scouring agent of the invention can reach the concise effect of traditional handicraft under conditions of low temperature even low alkali hypoxemia
Really, while meeting coloration requirements, energy consumption is saved, shortens the process time, sewage discharge is reduced, fabric weight-loss ratio and strength is reduced
Damage；
(2) low temperature scouring agent alkalinity of the invention is relatively low, while having hydrogen peroxide stabilizer, activates accelerator and concise
Infiltration, emulsification multiple efficacies.
