Embodiment 1

[0025] A kind of ready-to-use crown belt cord strip production process, comprises the following steps:

[0026] 1) twisted yarn, the high-strength nylon 66 industrial yarn is first twisted to obtain twisted yarn, and the first twist is carried out by a direct twister;

[0027] 2) ply twisting, the obtained twisted yarn is carried out ply twisting to prepare cord, and ply twisting adopts a direct twister to carry out;

[0028] 3) Weaving, weaving the ply-twisted cord, using an air-jet loom to make a white blank cord fabric, and the selvedge is seamed, and the seam is provided with multiple sets of selvedge weave on the meridian edge of the cloth body. Each group of warp selvedge weave is formed by intertwining a plurality of selvage warp yarns interwoven on the cloth body weft yarn;

[0029] 4) Glue dipping, the cord fabric is dipped in glue, the dipping machine is used for dipping, the formula of the glue is special, the glue is specially treated, after dipping, drying, stret...

Embodiment 2

[0037] The difference between this example and Example 1 is that the stabilizer is dilauryl thiodipropionate. The drying temperature is 230°C, and the stretching temperature is 240°C.

Embodiment 3

[0039] The difference between this embodiment and Example 1 is: the stabilizer is a mixture of 2,6-di-tert-butyl-4-methylphenol and dilauryl thiodipropionate, and the mixing ratio is Calculated in parts by weight and each accounts for half.

[0040] The drying temperature is 225°C, and the stretching temperature is 245°C.

Abstract

The invention relates to a production technology of an instant cap cord fabric strip applied to a tire cap ply. The production technology comprises the steps as follows: 1) yarn twisting: high-strength nylon 66 industrial yarn is twisted firstly and twisted yarn is prepared; 2) plying twisting: the twisted yarn is subjected to plying twisting and cords are prepared; 3) weaving: the cords subjectedto plying twisting are woven and fabric edges are subjected to edge locking treatment; 4) impregnation: cord fabric is subjected to special glue impregnation and special glue absorption treatment, and after impregnation, drying, drawing and setting treatment are performed, passive rolling and packaging are performed; 5) width separation; 6) strip separation and packaging. The instant cap cord fabric strip can be directly applied to tire forming and replace a calendered rubber cord fabric cap strip, multiple tire manufacturing processes are omitted, the consumption of tire cap ply rubber is reduced, and the production cost and the raw material cost of a tire plant can be substantially reduced.

Description

technical field [0001] The invention relates to a ready-to-use crown cord strip applied to tires, in particular to a ready-to-use crown cord strip applied to tires and a production process. Background technique [0002] The centrifugal force generated by the high-speed running of the tire will cause the diameter of the tire to increase at the non-contact point, and the belt layer will expand. stability. [0003] Because nylon 66 industrial yarn has the characteristics of high breaking strength, suitable dry heat shrinkage, moderate modulus, good heat resistance, etc., coupled with the high shrinkage force of nylon 66 industrial yarn, it helps to seal the crown layer and tighten the belt layer, so dipped cord fabric becomes the best choice for semi-steel radial tire cap layer. [0004] The commonly used crown belt in China is that after the tire factory purchases the cord fabric, it first presses rubber on both sides on the calender, then cuts it into 30-50 cm wide strips o...
