Problems solved by technology

[0006] The technical problem addressed by the present invention is: the density distribution of the cord fabric prepared by using the prior art steel reed and the cord fabric preparation method is not uniform, resulting in inconsistent numbers of crown strip cords after calendering and cutting of the cord fabric in the tire manufacturing process , so that the strength of the prepared tire cap layer is inconsistent, and the final tire lacks safety during use, especially when the load is large, there is a greater safety hazard

Embodiment 1

[0045] A kind of steel reed for preparing multiple groups of air warp marking structure cord fabrics, such as figure 1 , image 3 As shown, the reed includes an upper beam 1 and a lower beam 2 parallel to each other, and also includes reed teeth 4 and reed holes 6 between every two adjacent reed teeth; the reed teeth are vertically arranged on the upper beam and the lower beam Between the lower beams, and the two ends of the reed teeth are fixedly connected with the upper beam and the lower beam respectively, and bonded together by gluing; one side of the reed teeth body is provided with a weft thread groove 403 (all the reed teeth sides are grooves are provided, and all grooves are at the same height of the reed teeth.);

[0046] The reed teeth include a thin reed tooth 401 with a diameter of A mm and a thick reed tooth 402 with a diameter of B mm; wherein nine adjacently arranged thin reed teeth 401 and one thick reed tooth 402 are arranged adjacently to form a group of ree...

Embodiment 2

[0052] A kind of steel reed for preparing multiple groups of air warp marking structure cord fabrics, such as figure 2 , image 3 As shown, the reed includes an upper beam 1 and a lower beam 2 parallel to each other, and also includes reed teeth 4 and reed holes 6 between every two adjacent reed teeth; the reed teeth are vertically arranged on the upper beam and the lower beam Between the lower beams, and the two ends of the reed teeth are fixedly connected with the upper beam and the lower beam respectively, and bonded together by welding; one side of the reed teeth body is provided with a weft thread groove 403 (all reed teeth sides are provided with have grooves and all grooves are at the same height of the reed teeth.);

[0053] The reed teeth include a thin reed tooth 401 with a diameter of A mm and a thick reed tooth 402 with a diameter of B mm; ten adjacent thin reed teeth 401 and one thick reed tooth 402 are arranged adjacently to form a group of reeds Teeth 8, a tot...

Embodiment 3

[0058] A method for preparing a cord fabric with a plurality of sets of air warp marking structures, comprising the following steps:

[0059] (1) twisting:

[0060] Get 1440 pieces of nylon 66 with a fineness of 940dtex and place them in the twisting machine, control the rotating spindle to rotate to the right, and prepare 720 cords in the S twist direction (every 2 nylon 66 filaments prepare a curtain in the S twist direction line), put it aside; then take 1440 pieces of nylon 66 with a fineness of 940dtex and place them in the twisting machine, control the rotating spindle to rotate to the left, and prepare 720 cords in the Z twist direction (prepared by every 2 nylon 66 filaments) Take out a Z-twisted cord) and put it aside;

[0061] (2) Weaving:

[0062] With the viscose yarn as the weft, place the S-twisted cords and Z-twisted cords prepared in step (1) on the large creel in sequence, and then pass through the wire guide plate→filament collecting plate→splitting bar in ...

Abstract

The invention discloses a preparation method of a cord fabric with multiple groups of hollow warp marking structures and the cord fabric prepared by the preparation method. The preparation method comprises the following steps of: firstly, preparing cord threads in an S twisting direction and a Z twisting direction; secondly, crossly arranging the cord threads in the S twisting direction and the cord threads in the Z twisting direction, and preparing a grey fabric through an air jet loom provided with a reed; and carrying out gum dipping treatment to obtain the cord fabric with the multiple groups of hollow warp marking structures. According to the preparation method disclosed by the invention, reed teeth with different thicknesses are regularly arranged in the reed; the cord threads in theS twisting direction and the Z twisting direction are regularly arranged, so that the prepared cord fabric has a hollow warp effect and keeps clear hollow warp marks; the problem that the density distribution of the cord threads is not uniform is radically solved; and the uniformity and consistency of the strength of a tire cap ply are ensured and the safety of tire utilization is improved.

Description

technical field [0001] The invention belongs to the field of textile chemical industry, and in particular relates to a method for preparing a cord fabric with a multi-set air warp marking structure and the prepared cord fabric, in particular to a method for preparing a tire with a multi-set air warp marking structure cord fabric. [0002] technical background [0003] Nylon 66 dipped cord fabric uses strong strands as the warp and medium-fine single yarn as the weft. It is an important skeleton material for tires and is widely used in the cap ply of semi-steel radial tires. Moving at high speed, preventing the belt layer from detaching and maintaining the dimensional stability of the tire play an important role in driving safety. [0004] At present, there are a variety of cord fabric structure methods, but the existing cord fabric structure cords are closely arranged, and the warp density distribution of the dipped cord fabric can only tend to be uniform, but cannot be compl...
