Footwear Tester Bid for the Federal Technical and Vocational Training Institute



On September 14th last year, we wrote an article about Tender for Leather Tester at The Federal Technical and Vocational Training Institute. The machines in the article were not comprehensive, and only included three machines: Soling materials abrasion machine, Whole sole flexing machine, and Shoe lace abrasion machine (Lace to eyelet method). Some readers are curious about what other machines there are, and I will introduce them below.

​

Bata belt flexing machine

Determine the severity of the flexing action. Equipment should be supplied complete with three small pulleys of varying diameters to increase or decrease the amount of flexing. endless belt that accommodate six sole units, subject to the style and size. Sole units bonded to the belt using a strong adhesive. belt made of canvas and construction allows the number of complete cycles to be counted which is equal to the number of flexes of the test sample. The flexing area is provided with a full guard interlocked with the machine controls to ensure the guard cannot be opened until the belt has stopped. machine should be suitable for the testing of all shoe sole units and should be used with other flexible materials.
​Standards: SATM, ISO, DIN, SATRA.

Fiber Fineness and Tenacity Test

Image
  Test methods explanation We have tested 5 fiber samples using two solutions to test fiber fineness and tenacity: Solution 1 and solution 2. Solution 1 We use YG002C measured the fiber diameter, and YG005S tested the break force and extension. The fiber density is converted to denier from diameter using the formula. Then use the break force divide the density to get the tenacity. Please move to TABLE 1 to view the test result. We have attached YG002C parameter sheet in Appendix 1 and YG005S parameter sheets in Appendix 2. Solution 2 We use ZK100F measured the fiber density, and YG005X tested the break force, extension, and tenacity. Please move to TABLE 2 to view the test result. We have attached ZK100F parameter sheet in Appendix 3 and YG005X parameter sheet in Appendix 4. A better solution for fiber density and tenacity testing  We also have a YG005XD AUTOMATIC FIBER TENSILE AND FINENESS TEST SYSTEM, which has integrated function of ZK100F and YG005X; it is equipped wi...

Selection of materials for jigger dyeing machine parts

Image
In the textile industry, the jigger dyeing machine is a key textile printing and dyeing equipment. The selection of its main manufacturing material has a vital impact on the performance, durability, and dyeing effect of the equipment. Stainless steel is one of the most commonly used materials in modern dye jigger manufacturing, especially 304 and 316L. Material selection for each component of the jigger dyeing machine The jigger dyeing machine is composed of a frame, an electric control cabinet, a vessel/top cover, a circulation system, a dye bath, a main roller, a guide roller, a tension frame, an additional tank, a debatching device, and other parts. More details about jigger dyeing machine in our company No contact with dye solution ​ For parts that are not in contact with the dye solution, the main consideration when choosing the manufacturing material is the use environment of the equipment. Generally speaking, the environment of the dyeing factory is harsh. We recommend using 304...

Definition and Classification of Yarn Spinning

Image
  What is yarn spinning Yarn spinning is the technique of making yarn from fibers. The fibers can be wool, cotton or other natural materials, or they can be synthetic. Spinning produces a yarn that can then be used to make fabric. Types of yarn spinning Spinning can take numerous forms, but they all have the same goal: to transform fibers into yarn. Some varieties of spinning are more popular than others, but each has its own set of benefits. Woolen and cotton are the two most common forms of spinning. The process of converting raw wool into yarn is known as spinning. The yarn is generally thick and heavy since it is spun on a spinning wheel. Cotton spinning is the transformation of raw cotton into yarn. The yarn is generally thin and light, and it is spun on a spinning wheel or spinning jenny. There are also additional styles of spinning that are less common but have their own advantages. The process of converting raw silk into yarn is known as silk spinning. The yarn is generally...
