Description

A fabric softness testing device

Technical Field

The invention relates to the technical field of fabric testing, and in particular to a fabric softness testing device.

Background Art

The softness of a fabric refers to its softness in hand and touch, which is determined by factors such as the fabric's fiber type, fiber length, fiber fineness, weaving method, finishing treatment, and wear during use. The softness of a fabric not only affects the comfort and wearing experience of clothing, but is also directly related to its tactile quality in interior decoration and household items. Choosing the right fabric softness can be based on specific design requirements and usage scenarios to improve the overall product quality and user experience.

The drape of fabric refers to its natural draping effect when hanging or wearing. This is determined by factors such as the material, structure and weight of the fabric. Fabrics with better softness also have better drape. However, existing fabric softness testing devices cannot test the drape of different fabrics in a specific numerical way, so as to more concretely compare the softness of different fabrics.

Therefore, we proposed a fabric softness testing device to solve the above problems.

Compared with the existing technology, the advantages of this device are:

When the fabric sample contacts and blocks the laser sensing line between the laser sensor transmitter and the laser sensor receiver, the laser sensor transmitter sends a signal to the first motor, and the first motor stops driving. At this time, the distance scale of the right end of the pressing plate on the scale ruler can be recorded. Different fabric samples have different softness and thus different drapes. Fabric samples with better softness have greater curvature and can contact and block the laser sensing line faster, so that the distance scale of the right end of the pressing plate on the scale ruler is smaller. Conversely, the fabric with worse softness has a larger distance scale of the right end of the pressing plate on the scale ruler. The drape of different test fabric samples can be visualized as specific distance scales, so as to compare the softness of different test fabric samples and test the softness of different test fabric samples.

The base can be moved by pushing the handle and four universal wheels. When it moves to a specified position, the rubber strips in the two lifting structures press against the ground, and the base is fixed at the specified position through the resistance between the rubber strips and the ground.

In summary, the present invention can visualize the drape of different test fabric samples as specific distance scales, so as to compare the softness of different test fabric samples, test the softness of different test fabric samples, and can be moved and fixed at a specified position when moved to a specified position.

The first threaded rod 4 is driven to rotate by the first motor 7, so that the first moving block 6 can move left and right under the limit of the limiting rod 5.

A rectangular block 10 is fixedly connected to the upper end of the base 1, a first U-shaped track 11 is fixedly connected to the upper end of the rectangular block 10, a groove is opened at the left end of the rectangular block 10, a laser sensor transmitter 12 with the transmitting end facing left is fixedly installed in the groove at the left end of the rectangular block 10, an L-shaped bracket 13 is fixedly connected to the left end of the rectangular block 10, a laser sensor receiver 14 corresponding to the laser sensor transmitter 12 is fixedly installed at the right end of the raised part of the L-shaped bracket 13, and a scale ruler 15 is fixedly connected to the front end of the first U-shaped track 11. The inner bottom wall surface of the first U-shaped track 11 is smooth, and the pressing plate 9 is arranged corresponding to the first U-shaped track 11. When the first moving block 6 moves to the rightmost end, the pressing plate 9 can just fit into the groove of the first U-shaped track 11.
