preparation example Construction

[0013] A preparation method of a high-strength polyester fiber cord is realized through the following steps:

[0014] 1) Material selection: use polyester fiber filament after surface treatment, and its specification is 420D-1000D; the surface treatment process of polyester fiber is as follows: the polyester fiber is subjected to low temperature and atmospheric pressure plasma surface treatment for 20 to 35 minutes, and then sprayed Coupling agent dispersion, after the solvent is volatilized for 100 to 125 minutes, it can be subjected to low temperature and atmospheric pressure plasma surface treatment again for 13 to 15 minutes to obtain high-strength polyester fiber filaments after treatment;

[0015] 2) Doubling: 5-8 polyester filaments are used for doubling and 1 strand;

[0016] 3) Twisting: After paralleling, polyester fiber filaments are twisted through a twisting machine, and the transmission belt of the twisting machine is tight and tight. Each filament must be contro...

Embodiment 1

[0020] 1) Material selection: use polyester fiber filament after surface treatment, and its specification is 420D;

[0021] 2) Doubling: 6 polyester filaments are used for doubling and 1 strand;

[0022] 3) Twisting: The paralleled polyester filaments are twisted through a twisting machine, and the transmission belt of the twisting machine is tight and tight. Each filament must be controlled by a tension regulator, and its speed and twist are measured regularly. The twist is based on Depending on the size of the strands, generally less than 20 twists / m;

[0023] 4) Heat setting: heat setting the twisted polyester filaments through a steam setting machine at a temperature of 60°C and a pressure of 0.05Mpa for 30 minutes to obtain a strand 1;

[0024] 5) Forming: 3 heat-set polyester fiber strands 1 are twisted and formed by a rope twisting machine with a twist of 60 twists / m to obtain a high-strength polyester fiber cord that meets the requirements.

Embodiment 2

[0026] 1) Material selection: use polyester fiber filament after surface treatment, and its specification is 630D;

[0027] 2) Doubling: 7 polyester filaments are used for doubling and 1 strand;

[0028] 3) Twisting: The paralleled polyester filaments are twisted through a twisting machine, and the transmission belt of the twisting machine is tight and tight. Each filament must be controlled by a tension regulator, and its speed and twist are measured regularly. The twist is based on Depending on the size of the strands, generally less than 20 twists / m;

[0029] 4) Heat setting: heat setting the twisted polyester filaments through a steam setting machine at a temperature of 70°C and a pressure of 0.06Mpa for 50 minutes to obtain a strand 1;

[0030] 5) Forming: 9 heat-set polyester fiber strands 1 are twisted and formed by a rope twisting machine with a twist of 100 twists / m to obtain a high-strength polyester fiber cord that meets the requirements.

Abstract

The invention discloses a preparation method of a high-intensity polyester fiber cord thread. The preparation method includes the steps of: doubling polyester fiber filaments of which the surfaces are processed, twisting by using a twister with the twist of lower than 30 twist / meter, thermoforming, and twisting and molding by a closing machine; the prepared high-intensity polyester fiber cord thread is good in adhesiveness with rubber, high in intensity, good in heat-resistant performance, good in size stability and low in creep property.

Description

technical field [0001] The invention relates to the field of cords, in particular to a method for preparing high-strength polyester fiber cords. Background technique [0002] As we all know, cord is an important material for making tires and an important factor in determining the performance of tires. It has been widely used since the 1940s. However, the tire cords used all the time have low strength and cannot meet the normal use of the cords. Contents of the invention [0003] The object of the present invention is: to provide a preparation method of high-strength polyester fiber cord, the obtained high-strength polyester fiber cord has good adhesion to rubber, high strength, good heat resistance, good dimensional stability, and low creep Good sex. [0004] The technical scheme of the present invention is: the preparation method of high-strength polyester fiber cord, realizes by following steps: [0005] 1) Material selection: use surface-treated polyester fiber filam...
