Abstract
The invention discloses a quantitative evaluation method for the oil removing effect of an oil removing agent for a fabric. In the prior art, oil removing effect can only be observed with the naked eyes, so personal errors are great and quantification is impossible. The quantitative evaluation method provided by the invention comprises the following steps: 1) preparation of oily cloth; 2) oil removal of the oily cloth; and 3) evaluation of oil removal effect. In the step 1), the oily cloth is prepared by mixing an oil agent with a solvent to prepare a mixed oil-agent solution, then soaking a to-be-tested fabric in the mixed oil-agent solution, taking out the fabric and successively carrying out drying and high-temperature setting. The oil removal rate is calculated according to weight loss of the oil agent. The method provided by the invention is simple and convenient, produces objective, direct and accurate results, is applicable to all the fabrics and can be applied to industrial application evaluation of oil removal of fabrics.
Description
Technical field
The present invention relates to fabric degreaser field, especially a kind of method for quantitatively evaluating of fabric degreaser deoiling effect.
Background technology
Textile fabric during spinneret, wire drawing and weaving etc., in order to increase fiber smoothness, reduce fiber between and fiber
With the friction of machinery compartment, fibre cohesion is improved, protect fiber strength, reduce end breakage rate, need to add in a large number in weaving process
Spinning oil.In order to ensure the dyeability of fiber, prevent dyeing defect, color lake and silicone oil spot etc. from occurring, need to add before dyeing
Entering degreaser carries out pre-treatment to remove the finish on cloth cover and greasy dirt to fabric.Degreaser is the most frequently used during fabric finishing is processed
One of auxiliary agent.
Traditional degreaser deoiling effect evaluation method is：Black oil, gear oil and white mineral oil are mixed according to a certain percentage
Conjunction is made into finish to be removed, and is added dropwise in test fabric, carries out oil removing process experiment, then according to oil mark color before and after oil removing
Depth change judging the difference of deoiling effect.In experimentation, miscella often by the way of high-temperature baking come plus
The color of deep oil, becomes apparent from the color distortion of last oil.
There are some obvious defects in above-mentioned evaluation method：First, deoiling effect can only be observed by the naked eye, human error
Than larger and not energetic.So cause the limitation of test data application very big, can only now do existing use.Secondly, the method
Mainly use finish color to judge the difference of deoiling effect, thus true reflection be the amount for having color finish on a small quantity change
Change.In oil, the intensification of color is often because caused by the oxidation of small part oil, the oil of discoloration only accounts for little the one of whole finish
Part, hence with shade change can only judge to change colour oil change number, and the change of all finish amounts can not be reflected
Change.The oil molecule of oxidation stain, often oily polarity can change, special phase between the special functional group of generation and fiber
Interaction, has differences can taint-free oil and the oil of discoloration.Finally, different types of oil performance is different, to fiber
Affinity it is widely different, this requires that oil removing object will be directed to the corresponding finish of Sexual behavior mode as oil removing process changes, existing
Some methods can not meet requirement.
Therefore, a kind of new method for quantitatively evaluating is needed at present so as to have the advantages that to evaluate accurate, with strong points, energy
The deoiling effect of enough accurate quantification weaving degreasers, experiment are convenient and reliable, are the objective deoiling effect provider judged on fabric
Just.
The content of the invention
The technical problem to be solved is to overcome to exist in prior art to be unable to quantitatively evaluating deoiling effect and use
Finish shade is judging the defect of deoiling effect, there is provided a kind of fabric that can simply and easily provide oil removal rate data is removed
The method for quantitatively evaluating of finish deoiling effect, which is capable of the deoiling effect of accurate quantification weaving degreaser, is objective judgement fabric
On deoiling effect provides convenient.
For this purpose, the present invention is adopted the following technical scheme that：A kind of method for quantitatively evaluating of fabric degreaser deoiling effect, its
It is characterised by, it comprises the following steps：1) oilcloth makes, 2) oilcloth oil removing, 3) deoiling effect evaluation；
Described step 1) in, the manufacturing process of oilcloth includes：Finish and solvent are mixed into into finish mixed solution, then
Test is weaved cotton cloth and is soaked in being put into finish mixed solution, take out drying, and high-temperature shaping；
Oil removal rate is calculated by the weight loss of finish, test is weaved cotton cloth and weighed, record data W1；Oil, dry and high temperature
Weigh after sizing W2；Washing after oil removing process is dried, and weigh W3, go the computing formula of oil cut rate as follows：Remove oil cut rate=(W2-W3)/
(W2-W1) × 100%.
The creativeness of the present invention is that the weight loss of test oil after artificially oiling on weaving cotton cloth calculates oil removing with this
Agent oil removal rate data.
Further, described oilcloth oil removal process includes：The oilcloth that 1) above-mentioned steps obtain is put into into oil removing under room temperature
In working solution, then 50-130 DEG C is warming up to 1-5 DEG C/min of heating rate and is incubated 10-120 minutes, after then lowering the temperature
Cold water is washed, and is dehydrated and is dried.
Further, described oil removing working solution includes：Degreaser 0.1-30g/L, sodium carbonate or NaOH 0-20g/
L。
Further, step 1) in, described solvent be chloroform, dichloromethane, hexamethylene, benzene, toluene, acetone,
Ether, petroleum ether, methyl alcohol, ethanol or isopropanol.
Further, step 1) in, described solvent is hexamethylene, dichloromethane, petroleum ether or ether.
Further, step 1) in, the finish is 1 with the mass ratio of solvent:1-99, described finish are mineral oil
(such as 5# white oils), machine oil (such as 46# machine oil), dimethicone or atoleine, described degreaser are described effectively to remove
The material of finish, such as commercially available degreaser BS-220 (Jiande white sand), commercially available degreaser FWK (Rudoiph), degreaser TF-115K
(Zhejiang development of evil in febrile disease) etc..
Further, step 1) in, test is weaved cotton cloth and is cut into square, circular or rectangle, and is blocked using high temperature.
Further, step 1) in, soak time is 10 seconds to 24 hours.
Further, step 1) in, drying temperature is 25-100 DEG C, and drying time is 1-48 hours.
Further, step 1) in, setting temperature adopts 100-200 DEG C.
The method of the present invention, can intuitively understand the quality of deoiling effect by going oil cut rate data, it is to avoid rely on finish
Color change judges the defect of deoiling effect, and method is simple and convenient, as a result objective directly and accurate, fiber weaving cloth is had pervasive
Property, can very well suitable for the evaluation of fabric oil removing commercial Application.
Description of the drawings
Fig. 1 is that AEO6 straight chains alcohol ether surfactants remove oil cut rate figure under different amounts in application examples of the present invention 1.
