Abstract
The invention discloses a production method of chinlon cord fabrics with high rubber coverage rate. The production method comprises the following steps of: feeding chinlon industrial yarns into a straight twisting machine to be twisted into chinlon twisted silks, weaving the chinlon twisted silks into chinlon cord fabrics by a weaving machine, impregnatinh the chinlon cord fabrics into impregnation liquid, drying, drawing, and sizing to obtain the chinlon cord fabrics with high rubber coverage rate, wherein the impregnation liquid is am-cresol latex solution, the volume percent concentration of the m-cresol latex solution is 7+/-0.5%, the temperature of the impregnation liquid is 25+/-0.5DEG C in the process of impregnation, and the impregnation time is 5+/-0.5h. The production method disclosed by the invention is simple and easy to operate, and low in cost, the chinlon cord fabrics with high rubber coverage rate can be produced, the service life of a tire can be guaranteed, and the safety factor of vehicles can be further improved.
Description
Technical field
The present invention relates to a kind of production method of high coverage polyamide cord fabric.
Background technology
At present, the framework material that domestic rubber plant makes tire all adopts polyamide cord fabric, and this index of coverage is not arranged in the cord fabric national standard, and the client is not high to this requirement yet.The coverage of existing cord fabric is not high, and such cord fabric will directly affect tyre life.
Summary of the invention
The object of the present invention is to provide a kind of production method of high coverage polyamide cord fabric, the method can be produced coverage and reach 95% polyamide cord fabric, thereby overcomes deficiency of the prior art.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of production method of high coverage polyamide cord fabric, may further comprise the steps: nylon industry filament is sent into straight twister add and be twisted the polyamide fibre twisted silk, the polyamide fibre twisted silk is made into polyamide cord fabric by Weaving-machine, again polyamide cord fabric is placed the dipping solution impregnation, then obtain high coverage polyamide cord fabric by dry, stretching, typing, described dipping solution be between first liquid latex solution, this first liquid latex concentration of volume percent is 7 ± 0.5%, glue temperature is 25 ± 0.5 ℃ in the described immersing glue process, and the impregnation duration is 5 ± 0.5h.
Preferably, formaldehyde and resorcinol mass ratio are 1:1.8 in described first liquid latex.
Particularly preferred, described first liquid latex is to prepare under the condition of 25 ± 1 ℃ of temperature.
Preferably, described first liquid latex stored by clamping device, and logical cooling water circulation, and this cooling water temperature is 23 ± 2 ℃.
The present invention plays the monitoring stoste extent of reaction by control stoste color ratio, and is take perusal as main method, more stable than traditional handicraft, and it is little to fluctuate.
Compared with prior art, beneficial effect of the present invention is: the method is simple and easy to do, and cost is low, can produce the polyamide cord fabric of high coverage, has guaranteed the service life of tire, and then has improved the safety coefficient of vehicle.
Description of drawings
Fig. 1 is the process chart in one embodiment of the present invention.
The specific embodiment
Consult Fig. 1, nylon industry filament is sent into straight twister after, first twist, retwist are once finished, and twist with the fingers to for the S sth. made by twisting, obtain the polyamide fibre twisted silk; The polyamide fibre twisted silk becomes polyamide cord fabric by the Weaving-machine twisted weave, wherein the parallel of polyamide cord fabric is cotton yarn, polyamide fibre twisted silk lot number in the twisted weave process on same warp bobbin is as far as possible for approaching with lot number or lot number, can make like this with each polyamide fibre twisted silk inherent quality on the bolt and reach unanimity, each fabric guide roll of cloth machine board or pressure roller are wanted parallel and level, the limit warp of polyamide cord fabric is taked to prolong equilibration time or is suitably processed as without the tension force rewinding, keep simultaneously the stable of air-conditioning humiture, can make the generation and the cloth cover that reduce broken end in the production process bright and clean; First liquid latex solution between the polyamide cord fabric that twisted weave goes out immerses, first liquid latex concentration of volume percent is 7% in the middle of it, and glue temperature is 25 ℃ in the described immersing glue process, and the impregnation duration is 5H; Polyamide cord fabric behind the impregnation is sent into first dry drying room and is carried out drying, and baking temperature is 130-160 ℃; Send into the stretching drying room out again and stretch, draft temperature is 190-215 ℃; Then through the typing of typing drying room, setting temperature is 190-205 ℃; Batched by the storage cloth holder at last.
First liquid latex compound method is in the middle of it: first liquid (resorcinol+formaldehyde) between preparing first, put at room temperature maturation 5H, and then with first glue between first liquid preparation between maturation (a first sol breast), formaldehyde and resorcinol mass ratio are 1: 1.8 in its middle first liquid latex, room temperature is controlled at 25 ℃, stored by clamping device after the preparation, and logical cooling water circulation, this cooling water temperature is 24 ℃.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the rights protection scope of the present invention.
Claims (4)
