Embodiment 1

[0019] In the production process of cord fabric, a direct twisting machine with electric spindles as the transmission mode and 230mm spindle pot is adopted, and a multi-warp beam with multiple discs with an outer diameter of 1600mm, an inner diameter of 320mm and a disc edge distance of 2600mm is adopted. The warping machine adopts an air-jet loom with electronic let-off and large-capacity cloth winding device for production; by controlling the white gray fabric width to about 158cm, using the Pexul glue system, the white gray fabric width is designed to be profiled on the reed. 5 Gradually reduce the warp density of the steel reed at 14cm on both sides, continuously and gradually control the warp density, and change the arc expansion roller to a three-finger full-width expander and a half-width expander; the angle of the side warp tension cylinder is higher than that of the middle tension cylinder Small 3°, the replacement frequency of the rough skin on the surface of the let-o...

Abstract

The invention provides a production technology of tyre fabric for tyres. The production technology includes the operating steps of twisting, fabric weaving and rubber dipping. The tyre fabric is produced according to the parameters that a straight twisting machine, a warping machine and an air jet loom are adopted for production, the width of grey cloth is set between 155 cm and 160 cm, an arc-shaped spreading roller is changed into a three-finger full-range expander and a semi-range expander, the rubber dipping liquid is a Pexul system, the density of warps of reeds is reduced, the angle of a side warp tension drum is smaller by 1 degree to 5 degree than that of a middle tension drum, the replacing frequency of a rough-face shell wrapping the surface of a warp pacing roller is replaced once every 24 hours to 48 hours, and a roller on the rubber dipping machine is cleaned once every 48 hours to 72 hours. Due to the improvement in the production technology, the density of the warps of the tyre fabric tends to be consistent, not only are the texture and the structure guaranteed, but also the physical performance and the appearance quality of the tyre fabric are kept, rubber can permeate mutually easily in the calendaring process, the stress borne by a tyre can be consistent easily, side lines of the tyre are prevented from being exposed, and large potential safety hazards such as delaminating are avoided.

Description

Technical field [0001] The invention relates to a textile production process, in particular to a production process of tire cord fabric. Background technique [0002] Tyre cord fabric is a skeleton fabric for tires woven with strong strands as warp and medium and fine single yarn as weft. The weft fixes the position of the warp, which is also called the cord, which bears the load. The cords include cotton cord, viscose cord, nylon cord, steel cord, nylon cord, polypropylene cord, aramid cord, carbon fiber cord, PEN cord, etc. Since the cord fabric is used as the skeleton of rubber products such as tires, in order to make it have the ability to withstand huge pressure, impact load and strong vibration, the cord is required to have: ① high strength and initial modulus; ② heat resistance; ③ fatigue resistance; ④ Stable structure; ⑤ It can bond with rubber and other properties. [0003] However, in the process of weaving and dipping, the cord fabric is affected by various factors su...
