Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
The present embodiment will be described in detail with reference to fig. 1 and 2. The high-temperature-resistant thermal transfer printing cloth comprises a polyester fiber layer 1 and a transfer printing layer 2.
The polyester fiber layer 1 is formed by carding conventional polyester fibers, and a plurality of bonding points are arranged inside the polyester fiber layer. The bonding points are bi-component polyester fibers. The polyester fiber layer 1 comprises a cross lapping layer 11 and a parallel lapping layer 12; the gram weight ratio of the cross lapping layer 11 to the parallel lapping layer 12 is 7:3-5:5, and in the embodiment, 7: 3. the transfer printed layer 2 is adjacent to the parallel ply layer 12.
In this embodiment, conventional polyester fibers and bicomponent polyester fibers are mixed according to a predetermined ratio, and then subjected to opening, cotton mixing and carding, and then a cross lapping layer 11 and a parallel lapping layer 12 are formed in a cross lapping and parallel lapping manner. In the process of forming the fiber web, the forming speed of the fiber web in the parallel lapping mode is higher than that of the fiber web in the cross lapping mode. When the cross lapping mode is used for forming the net, the fiber net has small ration, the carding speed of the carding machine can be improved, and the forming speed of the cross lapping layer 11 can be improved. It can be seen that the use of two layers of cross-plied 11 and parallel-plied 12 arrangement increases the speed of web formation.
In this embodiment, the cross section of the bicomponent polyester fiber used can be a sheath-core structure or a side-by-side structure. The bicomponent polyester fiber of the sheath-core structure comprises a sheath layer and a core layer, wherein the sheath layer is low-melting-point PET, and the core layer is conventional PET. The bicomponent polyester fiber in the parallel structure comprises an A part and a B part. Part A is low melting PET and part B is conventional PET. So that the melting point of the low-melting PET is 180 ℃; the melting point of the conventional PET is 250-255 ℃. Specifically, the sheath-core bicomponent polyester fiber is selected in the embodiment, and the area ratio of the sheath-core bicomponent polyester fiber to the core-core bicomponent polyester fiber on the cross section is 1: 1. firstly, hot-roller hot pressing is carried out on the polyester fiber layer 1, so that the low-melting-point PET on the surface can be melted, and the surface is smooth.
The temperature range during the thermal transfer printing is about 200 ℃, so that the low-melting-point PET can be melted at the treatment temperature, the conventional PET as the core layer can not be melted, the two-component polyester fiber can not be completely melted, and the strength of the two-component polyester fiber can be kept to a certain extent. In the conventional hot-melt type fiber, the PE/PP double-component fiber with a sheath-core structure is also adopted, so that the fiber is not selected, and the strength of the whole polyester fiber layer is greatly lost due to the fact that the PE and the PP which are two raw materials are completely molten at the heat transfer temperature.
The fineness of the bicomponent polyester fiber used in the embodiment is 4D, and the length is 51-64 mm; the fineness of the conventional polyester fiber is 1.56dtex, and the length of the conventional polyester fiber is 51-64 mm. Specifically, the length of the wool-type fibers is 51 mm.
Example two
The present embodiment will be described in detail with reference to fig. 1 and 3. The difference between the high-temperature-resistant thermal transfer printed cloth related to the embodiment and the embodiment I is that the selected bicomponent polyester fibers are in a parallel structure. The cross section of the bicomponent polyester fiber is round, runway-shaped, dumbbell-shaped or peanut-shaped. The area weave ratio of the part A and the part B is 1: 1. the shapes of the various cross-sections are shown in fig. 3a, 3b, 3c, 3d, respectively.
EXAMPLE III
The high temperature resistant thermal transfer printed cloth according to this embodiment will be described in detail with reference to fig. 4 and 5. The present embodiment is different from the second embodiment in that a microporous membrane 3 is combined on one side of a cross-laid web layer 12 of a polyester fiber layer 1. The microporous membrane 3 of (2) has micropores having a pore size between the diameter of a water molecule and the diameter of an air molecule. The microporous membrane 3 is one or the combination of any two layers of TPU film, PVC film, PE film or foaming PVC film. In the present embodiment, a TPU film is selected
In the embodiment, the selected bicomponent polyester fibers are in a side-by-side structure. The cross section of the bicomponent polyester fiber is circular, and the bicomponent polyester fiber sequentially comprises a part A, a part B and a part A.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
