Introduction With the development of the textile and clothing market, various new materials emerge one after another incessantly, the effects of materials on the clothing style and shape is more and more prominent in fashion design, materials even becomes one of the key factors determining design’s success or failure.
Twenty different commercial types of suit materials with various fiber content, blend composition, fabric weave, unit mass, and end uses were selected for the study.

Therefore, the sensor mentioned above may obtain the best performance when the height of the dielectric-layer is 30mm. 3) Impact by the material of the dielectric-layer Respectively set the relative dielectric constant of the dielectric-layer material to 3, 4, 5, 6, and 7, the He–frequency curves were obtained and shown in Fig. 5.
Therefore, the dielectric-layer material has important impact on the performance of the disc-type sensor.
When the requirements of the detection bandwidth were meet, it would be recommended to use those materials which have a low. 4) Iimpact by the radius of the bottom-plate Respectively set the radius of the bottom-plate to 110mm, 120mm, 130mm, 140mm and 150mm, the He–frequency curves were obtained and shown in Fig. 6.

Narrow manufacturing resources mainly refer to the material elements needed to manufacture one component.
Being the bottom manufacturing resources in a manufacturing system [4], narrow manufacturing resources include machine, tools, fixtures, gauges and materials and so on.
According to the phase properties of the manufacturing resources and by defining them in the extensive conception, the manufacturing resources are divided into nine categories as follows: (1) Special-specific products; (2) Standard parts resources; (3) Equipment and material resources; (4) Design knowledge resources; (5) Software system resources; (6) Experts human resources; (7) Training resources; (8) Science and technology information resources; (9) Other resources.
