Embodiment 1

[0043] This method was used to evaluate the oil absorption performance of PP spunbonded nonwovens. The net weight of non-woven fabric is 40g / m2. The liquid is selected from commercially available Arowana soybean edible oil. Cut the same batch of spunbond fabrics into 10*10 (mm) pieces for later use. During the experiment, the sample to be tested is placed on the tray. Firstly, the pre-test is carried out, that is, 0.2ml, 0.4ml, 0.6ml, 0.8ml, 1ml, 1.2ml, and 1.4ml of oil are dropped on the surface of the spunbond cloth, and the voltage values ​​before and after the experiment are recorded. Then carry out the liquid dynamic absorption test experiment. A fixed volume of oil was dropped on the surface of the spunbonded cloth within a specified time, and the voltage change with time before and after the receiver experiment was recorded. image 3 is the curve of the previous experiment. Figure 4 It is the voltage change curve of receivers E and F in the liquid dynamic absorpti...

Embodiment 2

[0047] This batch of PP spunbonded nonwovens is still used. The liquid is commercially available No. 0 diesel oil. The implementation process is the same as in Example 1. The four indicators for obtaining the oil absorption performance of textile materials are:

[0048] Table 2

[0049] IAR(ml / 0.02s)

[0050] It can be seen that the spreading of No. 0 diesel oil on the surface of the spunbonded nonwoven fabric reflects the outstanding one-way transfer performance. Comparing Examples 1 and 2, it can be seen that the initial absorption rate and maximum absorption volume of diesel oil by spunbond cloth are greater than that of edible oil. The surface spreading time used by diesel oil is less than that of edible oil, indicating that diesel oil has a faster transfer speed on the surface of spunbond fabric.

Embodiment 3

[0052] The commercially available Arowana soybean oil was used to evaluate the oil absorption performance of five nonwoven fabrics. The five nonwoven specifications are listed in Table 3. The testing process is the same as above. The test results are listed in Table 4. The liquid absorption rate change curves of the five samples are shown in Figure 7 . From the test results in Table 4, we can evaluate the oil absorption performance of these five nonwoven fabrics. The maximum oil absorption volume of sample 3 is the largest among the five textile materials, followed by sample 1, sample 4, sample 2, and sample 5. Sample 5 had a larger one-way transport coefficient, indicating that the edible oil was transported significantly more in one direction than the other across the surface of this sample. In addition, by Image 6 It can be seen that sample 3 has a faster initial oil absorption rate, which means that sample 3 can quickly absorb edible oil in a short time. However, ...

Abstract

The invention provides a device and method for evaluating the liquid absorption performance of textile materials quickly and without contact. The invention can systematically evaluate the liquid absorption performance of the textile material through the proposed four indexes. At the same time, the method does not require liquids, and is applicable to almost all types of liquids. Different from the limited alternative liquids of MMT, when using this method to evaluate textile materials, it can break through the limitation of liquid selection and use almost all liquids. The only exceptions are liquids which are volatile and damaging to textile materials. In addition, this method can quickly measure the initial absorption rate and maximum absorption capacity of textile materials when absorbing liquid, and finds an evaluation standard for fast liquid absorption textile materials. This method can also be used to evaluate the spreading properties of liquids on the surface of textile materials.

Description

technical field [0001] The invention relates to a textile material evaluation method, in particular to measuring the spread and penetration of liquid in the textile material by using radiation, and in particular to a method for evaluating the liquid absorption performance of the textile material. Background technique [0002] The study of the liquid absorption properties of textile materials, especially the water absorption properties, has been receiving a lot of attention worldwide. Reifler used neutron radiation technology to study the transfer performance of water inside textile materials; Conrath used high-speed cameras to record the expansion process of water on the surface of textile materials from outside to inside and from inside to outside; An intelligent system is designed to observe the expansion of water on the upper and lower surfaces of textile materials. [0003] Some of the above-mentioned methods are very time-consuming and labor-intensive, such as using h...
