Innovation of contact pressure control system of PA66 tire cord winding machine;

Present situation and development of PET industrial yarn and PET tire cord for automobile;

Discussion of twisting process of 1 100 dtex PET tire cord on a direct twisting machine;

Preparation of high-strength-low-shrinkage nylon 66 tire cords;

Development of finishes for high-speed spun PA6 tire cord;

The paper mainly introduced polyester cord yarn industry from the aspects of development course,the status quo of production at home and abroad,the technology,characteristics,classification and application prospect in market etc.

The adhesion of PET cord yarn treated by low temperature plasma was studied in this paper.

The research on the adhesion between PET cord and rubber;

By the contrast test of breaking strength and breaking elongation of nylon tire cord,the test principle and characteristic of tensile strength tester tympanic topcoat is expounded,the tympanic type topcoat and the flatslab type topcoat difference and its corrected method is dissertated.

The performance of cords is required higher and higher with the development of the tire industry.

This paper introduced the tension variation of warp yarn during the weaving procedure and analyzed the influence of this variation on cord fabric.

There exist some troubles as the vulcanized rubber and the powdered gum in dipped tire cord fabric course of production.

Experiments on changing fomula of nylon6 dip solution find that there has a constant ratio betwen RFL viscosity and adhesion by H test of nylon6 dipped cord fabric.
