TH21328B - Webbing for seat belts and how to manufacture webbing for use as seat belts - Google Patents

Abstract

The DC60 revealed is a thin and light webbing that has a high unit-to-unit strength while maintaining abrasion resistance. And uses a multi-fiber polyester yarn with Great strength for seat belts made from fine threads of each thread. Longitudinal The yarn is obtained by performing a high degree of twisting process which is not Applied for the original seat belt with a new twist method, very low cost, in the part of Polyester multifilament yarns are made from the fibers of each fine yarn. In order to achieve high adhesion, which is not the same as the previous method, is used as a longitudinal yarn. Polyester multilayer yarns of each fine thread are It is important to weave with the highest tensile rate in the yarn manufacturing process to obtain polyA fibers. The new sprocket is very strong for seat belts. Polyester monofilament and / or monofilament yarns were used as strands. By making yarn The diagonal and longitudinal threads are crossed so that they are woven into a belt-like structure. Thus resulting in a strap With high unit strength per unit length Using low cost base yarn and still have abrasion resistance What was revealed is a thin and light webbing that offers high unit-to-unit strength while maintaining abrasion resistance.

Claims (9)

1. The harness for the seat belt consists of Longitudinal yarns include main base straight threads and cross threads. where the flux of the webbing consists of polyester filaments, where the webbing is woven with such webbing and the webbing using Crosswise fiber density, which meets the relationship between fiber density. such transverse line with the resolution of such transverse fibers defined Crosswise fiber density (tip/3cm) x (D2)1/3 > 175 where D2 refers to the total denier of multi-filament or filament yarns. One filament or both yarns used for such cross threads Multi-fiber polyester consists of a number of polyester fibers that are Yarn strength at 10 g/denier or more and each fiber has a fiber resolution On average, each line is 7 denier or less. Each multifilament polyester yarn is Twist with a torque coefficient alpha of 4000 or more. The aforementioned alpha yid coefficient is obtained by alpha = T x (d1)1/2, where T denotes the number of twists t/m and D1 indicates the denier of the multi-thread yarn. fibers for such straight threads 2. Webbing for seat belts according to claim 1, where webbing is woven on a needlepoint loom. 3. Webbing for seat belts according to claim 1 or 2, where the strength of Each strand of such multifilament polyester yarn is made up of at least one piece. The main floor length piece of yarn for the webbing is 9 g/denier or higher after the webbing has been subjected to a dyeing process. The process of making the coagulation by heat or skin dressing one already 4. Webbing for seat belts according to claim 1, where multi-filament polyester, monofilament polyester or both yarns are used as yarns. the cross-section of the strap 5. Webbing for seat belts according to claim 1 where multi-fiber yarns The fineness is less than the fineness of the multi-filament yarn used for longitudinal yarns. Such a staple is used as a longitudinal thread that forms a frayed edge in the webbing for seat belts. 6. The manufacturing method for seat belt webbing consists of the steps of placing at least a certain amount of polyester multi-fiber yarn into part of the floor length thread of the webbing which each yarn consists of yarn Polyester with a yarn strength of 10 g/denier or more and a number of polyester filaments. in which each filament has an individual filament resolution of 7 denier or less on average, and each such multifilament polyester yarn is also twisted. Torsion coefficient alpha of 4000 or more. where the alpha twist coefficient is obtained by alpha = T x (D1)1/2 where T denotes the number of twists t/m and D1 indicates the denier of the multi thread. fibers for such long yarns Such multifilament polyester yarn is fed into the weaving process in while twisting the multi-fiber polyester yarn at the same time and weaving the webbing with such multi-fiber polyester yarn and the webbing predefined as a crosswise yarn 7. The method of manufacture of harnesses for seat belts according to claim 6, where the horizontal threads Such a thread is inserted into the row of such longitudinal yarns with a longitudinal yarn density determined by the weft density (tip/3cm) x (D2)1/3 > 175, where D2 means To all deniers of multi-fiber or filament yarns One filament or both yarns used for such cross threads 8. The method of manufacturing harnesses for seat belts in accordance with claim 6 also consists of the procedure for installing a number of bobbins with untwisted polyester multifilament yarns. The above goes on a basket with a suitable twisting mechanism as a long thread feeding path. Pull each strand of polyester multifilament yarn that acts as a longitudinal yarn. Take out each such bobbin mounted on the basket, respectively, and twist the polyester yarn. Such multi-fiber yarns are fed during the traction process of such yarns. Enter the bending process continuously and feed the long polyester yarn that has been bent into the weaving process like Continuing to weave the straps up 9. The method of manufacturing harnesses for seat belts in accordance with claim 6 also consists of the procedure for installing a number of bobbins with untwisted polyester multifilament yarns. The above is mounted on a basket with a suitable twisting mechanism as a way of feeding the long threads. Pull each multifilament polyester yarn that acts as a longitudinal yarn. Leave each such bobbin mounted on the basket, respectively, and twist the thread. During the yarn traction process, the twisted multi-filament longitudinal polyester yarn is then fed. It enters a continuous coarse fabric production process to produce coarse fabric, and such long polyester yarns, which are part of the coarse fabric, are fed into a continuous weaving process to make webbing.
