Description

Technical Field

[0001] The invention relates to the field of textile testing, and more specifically to a push-down driven weighing drying rate tester and a testing method. Background Art

[0002] In the field of textile testing, water evaporation / drying rate is one of the important comfort testing items. When the human body excretes sweat, the fabric can use its own material, fabric structure and other characteristics to absorb sweat and dry the sweat quickly, keeping the human body in a more comfortable state. The drying rate can intuitively reflect this performance of the fabric. There are many ways to test the drying rate. The simplest and most commonly used method is to add a specified amount of water to the fabric, then hang it to dry, weigh the mass change at regular intervals, and calculate the change in water per unit time or the drying time when all the water is dried.

[0003] At present, the commonly used drying rate test methods include the determination of evaporation rate in ISO 17617 and GB / T 21655.1. The actual test process can be divided into automatic and non-automatic tests. In non-automatic tests, the entire test process is manually operated by the tester. First, the mass of the sample hanging rod is measured, and then the sample is hung on the sample hanging rod. The mass of the sample hanging rod and the sample without water is weighed, and the mass of the sample without water is subtracted from the two. Then the sample is removed, a specified amount of water is added, and finally the sample is hung on the sample hanging rod again. Manual weighing is performed at specified intervals. The test process is very time-consuming and inefficient, and the speed and weighing time of manual weighing are uncontrollable, which is easy to cause errors.

[0004] The automatic test method can use instruments to complete automatic weighing. The patent names of the main instruments used are Water Evaporation Rate Tester (application number 201410779448.8, published on March 11, 2015) and utility model name A Textile Water Evaporation Rate Tester (application number 201520838577.X, authorization announcement date March 9, 2016). Both patents have two sets of drive devices, namely, a drive device for horizontally rotating sample racks and a drive device for vertical lifting and weighing. When weighing a sample, the drive device must raise and lower the sample rack and all sample racks. The structural design is relatively complex and the energy consumption is high. The upward-lifting drive weighing structure is not easy to repair after a failure; and the patent can only test samples in a suspended state (i.e., method A in ISO 17617, simulating a vertical drying state), and cannot test horizontally placed samples (i.e., method B in ISO17617, simulating a horizontal state of fabric in contact with the skin).

[0005] Therefore, the current automatic drying rate measurement device has the following problems: 1. The drive weighing structure is complex in design, the instrument movement friction loss is large during use, and the upward lifting weighing drive device is complex in design and not easy to maintain. 2. The sample suspension mode is a single vertical suspension state, and the sample state of the sample placed horizontally cannot be tested.

[0006] Therefore, in response to the above-mentioned problems, a push-down driven weighing drying rate test device for suspended and horizontally placed samples was designed. The driving weighing structure is very simple, which reduces energy consumption and failure rate, and is easier to maintain. Summary of the invention

[0007] In view of the above-mentioned problems of the prior art, the present invention proposes a push-down driven weighing drying rate tester and a testing method. The problems that the present invention intends to solve are: 1. The design of the driving weighing structure is complex, the friction loss of the instrument movement during use is large, and the upward lifting weighing drive device is complex in design and not easy to maintain. 2. The sample hanging method is a single vertical hanging state, and the sample state in which the sample is placed horizontally cannot be tested. The present invention redesigns the weighing structure, including a sample rack, a turntable, a sample hanging rod and a sample support plate, etc., which can measure the drying rate of the fabric in a flat and hanging state, and redesigns the push-down weighing method, which can test each sample one by one without having to lift all the samples.
