A pneumatic tire includes a carcass ply with carcass cords. The carcass cords comprise high tenacity vinylon fiber, polyethylene naphthalate fiber or polyalylate fiber. Viscoelasticity characteristics per one cord at 120° C. of the carcass cord satisfy the following equations (1) to (3):B>0  (1)B≦0.0000437×A+0.042857  (2)B≦−0.00003636×A+0.163636  (3)(wherein “A” represents a product of complex modulus E*(N / cm2) and cross-sectional area “S” (cm2) of cord), and “B” represents a loss tangent tanδ).

The invention provides a vinylon pure spinning fiber oil and its preparation method, which is composed of non-polar smoothing agent, surfactant, auxiliary agent and water, wherein the content of each component is: non-polar smoothing agent: 8-25%; in surfactants: 5-28% sulfate esters, 5-28% phosphate esters, 5-20% polyol fatty acid esters, 10-30% fatty alcohol ethers; in additives: neutralizer 2 ~11%, high molecular silicone polymer 0.5~5.0%, preservative 0.1%; the balance is water; all are calculated by weight percentage. Since the oil agent of the invention does not contain alkylphenol surfactants, environmental pollution is reduced. The fiber product treated with the oil agent of the present invention has good smoothness, softness, suitable cohesion (or clustering property), antistatic property, etc., so that the fiber can pass through various post-processing procedures smoothly, and has good spinnability; Moreover, it can be widely adapted to the process conditions of fiber production, such as heat resistance, oxidation resistance, corrosion resistance, and prevention of oily odor and deterioration caused by bacterial reproduction. The preparation method in the present invention is simple and does not need heating during preparation.

The present invention relates to a method for making a vinyon artificial bone fragment molding implant, and the method comprises the steps of: (a) preparing the raw material: filtrating the thin particle vinyon in initial state, the surface of the obtained particle has a plurality of prominent bulges which is irregular ellipse grain shape; (b) preparing the mold which is composed of a mold frame, a top mold board and a lower mold plate; (c) adding material: spreading the filtrated raw material uniformly in the mold cavity after weighting; (d) orientating the electrostatic: opening the electrical power switch of the electrostatic generator and adjusting the electrical voltage, executing slow horizontal moving scanning with the electrode bar at the voltage output end at the upper side of the mold, the upright particles inclines along with the moving direction of the electrode bar and the plastic particles are arranged with regulated cross net shape; (e) closing the mold cover and inputting the mold to the heating furnace to sinter when the process of the electrostatic orientating has finished. The artificial bone fragment made with the method of the invention has a cellular structure with a definite shape, facilitates the adhering and growing of the human organization, has an excellent bioavailability and physical property.
