Textiles - Determination of bending properties
Part 6. Saddle method
1 Scope
This section GB/T 18318 specifies the use of saddle method for measuring the bending resistance and rebound rate of the fabric.
This section applies to the grip height greater than 15mm fabric.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 6529 Textiles conditioning and testing standard atmosphere
GB/T 8170 rounded repair rules and limit values of the representation and judgment
3 principle
Will be a certain size of the specimen clamped to both ends of the sample holder, so that the specimen was semi-circular vertical ring, the ring part of the load imposed a certain load in the load
Under the action of the sample, the sample is flexed downward to a specified displacement and then returned to determine the corresponding bending resistance and rebound rate when the sample is bent a certain degree of displacement.
4 instruments and appliances
4.1 Instruments. It should include load cells, displacement sensors and control systems.
Force measurement error does not exceed ± 0.5%; displacement measurement range of at least 15mm, displacement measurement error does not exceed ± 0.1mm; run
Speed 50mm/min, accuracy of ± 10%.
Note. The sensor range is generally within 2N to meet the requirements.
4.2 sample holder. Clamping surface should be flat and nondestructive, no significant loose, good grip. Two jaw line should be the same height, spacing 15mm ± 0.1mm,
The distance from the jaw to the lower stop is 5mm ± 0.1mm. The effective width of the clamp is at least 50mm. The clamp should be placed on the workbench and should be stable.
4.3 appliances. Scissors, tweezers, cutouts or molds.
4.4 probe. Should adopt aluminum materials, process size shown in Figure 1.
5 sample
Avoid the defects and wrinkles that affect the test results on the sample and cut a sample with a width of 50 mm ± 0.5 mm and a length of 60 mm ± 0.5 mm
(As shown in Figure 2), the latitude and longitude (straight, horizontal) to at least five blocks, and according to Figure 2 on the sample painted clamping mark line. Sample should be at least cloth edge
150mm evenly distributed on the sample, the sample group should not be the same length (or straight) sampling, the weft (or transverse) sample group should not be
Sampling the same length.
