For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0022] like Figure 1-3 As shown, a webbing with crease recovery function includes a webbing body, wherein the webbing body is woven integrally with at least three kinds of yarns including warp yarn Y1, warp yarn Y2 and weft yarn Y3 and subjected to heat setting treatment, wherein the warp yarn Y1 is low elastic, the warp yarn Y2 is high elastic, and the weft yarn Y3 has mechanical elasticity and rigidity; the webbing body is woven in the warp direction with a 1 / n, n / n structure, wherein n is less than 11, and the weft density of the webbing body is m≥11 needles / cm, the low elasticity of the warp yarn Y1 and the high elasticity of the warp yarn Y2 refer to the elasticity of the warp yarn Y1 being less than the elasticity of the warp yarn Y2, and the definition here is the elasticity comparison between the warp yarn Y1 and the warp yarn Y2, for the convenience of description, rather than the specific numerical limitation of the elastic force of the warp yarn Y1 and the warp yarn Y2. By the structural transformation of the warp direction and the matching of the weft yarn with rigidity and mechanical elasticity, the recoverable space of the yarn in the warp and weft directions of the webbing is increased, thereby enhancing the crease recovery performance of the webbing.
[0023] The warp yarn Y1 may also be a non-elastic type yarn.
[0024] In addition, heat setting treatment is carried out to weaken the force between macromolecules in the fiber. Under a certain pressure, the original molecular chains are disassembled and re-bonded in new positions. After cooling and removing the external force, a new molecular arrangement state is formed, and the structure is more stable, which can enhance the crease recovery performance of the ribbon. The heat setting temperature is 100℃-200℃, the time is 1-3min, preferably 150℃, the time is 1min.
[0025] The warp yarn Y1 can be low-elastic or non-elastic, preferably low-elastic, with an elongation of less than 22%; the yarn Y2 is highly elastic, with an elongation of 400-800%.
[0026] The warp yarn Y2 is highly elastic and has a breaking elongation of 200-800%.
[0027] The weft yarn Y3 has an original length of 100 mm and a breaking elongation of 35 mm to 88 mm, preferably a breaking elongation of 55 mm to 65 mm.
[0028] The weft yarn Y3 has rigidity and elasticity and a DPF of ≥1.5. Within the rigidity range of the yarn, the greater the rigidity, the better the crease recovery performance of the fabric.
[0029] The warp yarn Y1 selects a 1 / 3 and 1 / 5 combination structure, that is, during the weaving process, part of the warp yarn Y1 adopts a 1 / 3 structure and part of it adopts a 1 / 5 structure, that is, a one high and three low, one high and five low structure; the warp yarn Y2 selects a 1 / 1 structure, that is, a one high and one low structure.
[0030] The weft density of the webbing body is m=15-18 needles / cm, preferably m=17.2 needles / cm.
[0031] In addition, the webbing body is a flat belt or a mesh belt.
[0032] Production example, weaving on a shuttle loom.
[0033] 1. Root package
[0034] Use N42040 / 32, which is double-wrapped with a core layer of 420D and an outer layer of 40 / 12 / 1SD.
[0035] 2. Warping preparation
[0036] The warp threads needed for the webbing are wound onto the disc head in different categories for weaving preparation. The warp threads are: N42040 / 32, 75D / 1SD low-elastic polyester. Among them, 56 threads of N42040 / 32 are used for the skeleton, and 422 threads of 75 / 1SD low-elastic polyester are used for the body yarn.
[0037] 3. Wear brown
[0038] like Figure 1 As shown, all warp threads are passed through the hard brown silk holes according to the warp yarn sequence on the threading diagram.
[0039] 4. Production density
[0040] The fabric density of this embodiment is 17.2 needles / cm.
[0041] 5. Width and reed
[0042] The width of this embodiment is 40 mm, the reed specification is 31, and there are 52 grids in total. Figure 1 Insert the warp threads into the designated grid positions of the reed in the order shown in the threading diagram.
[0043] 6. Weft
[0044] The weft thread in this embodiment is a 75 / 2 mechanical elastic polyester.
[0045] 7. Movement Laws of Organizational Structure
[0046] like Figure 2 As shown in the organizational structure diagram of this embodiment, Figure 2The arrangement of the flower chain parts is shown in FIG. 1 , wherein the 1st to 3rd frames are the skeleton structure of the webbing body, and the 4th to 11th frames are the surface and bottom structures of the webbing.
[0047] 8. Weft insertion and beating
[0048] The weft 75 / 2 passes through the weft conveyor and the weft hook. The weft hook drives the weft to cross the opening formed by the warp driven by the flower chain, and then passes through the weft up and down on the side line driven by the side hook. The side line is collected by the latch needle. The reed swings back and forth to compact the weft that passes through the yarn opening to form a webbing.
[0049] 9. The rubber wheel rotates under the driving traction of the density adjustment device to form the webbing.
[0050] 10. Heat setting
[0051] Heat the heat setting machine to 150℃ and 2KPA, feed the ribbon into the conveyor belt for heat pressing, and adjust the speed to 1min to complete the heat setting.
[0052] The finished webbing product is obtained and tested.
[0053] The crease test is carried out according to the test instrument suitable for testing the recovery angle of webbing. Take the sample block and fold it horizontally, place it horizontally under the pressure plate, and then add a certain weight to the pressure plate. After 30 minutes, release the pressure and quickly take out the sample. Align the fold line of the sample to the center line of the protractor, align one end of the sample plane horizontally with the 0 scale line, and read the angle of the two folded surfaces. This angle is the crease recovery angle. Usually, the recovery angle after a shorter recovery time of 10s is called the rapid elastic crease recovery angle, and the recovery angle after a longer time of 5min is called the slow elastic crease recovery angle. The crease recovery angle is greater than 140°.
[0054] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
