Description

Technical Field

[0001] The invention relates to the technical field of shoe material application, and in particular to a flexible, wear-resistant, high-tension rope and a preparation process thereof. Background Art

[0002] Knob locking systems are widely used in sports shoes and children's shoes. Knob locking systems are composed of ropes and knob-type locking systems for knob shoes. The two complement each other. In order to adapt to the mechanical force of the knob-type locking system for knob shoes, the ropes in the system must have high tensile strength, high wear resistance and high durability. At the same time, they must also have a variety of cross-sections and appearance shapes to meet the needs of knob-type locking systems for knob shoes of different sizes.

[0003] In order to meet the requirements of the knob-type locking system for shoes on the market, most of the current products use steel wire to enhance the physical properties of the ropes. The performance is improved after the use of steel wire, but in actual use, it is found that the ropes with steel wire cores are too weak in flexibility when locked, and are prone to pinching the feet, greatly reducing the wearing comfort of the shoes, and thus causing customer complaints. Ordinary fiber ropes have poor tensile strength, and when yarn is used to weave ropes, the commonly used chemical fibers are difficult to meet the locking requirements of the knob-type locking system for shoes, and the fibers are prone to fibrillation during the friction with the knob-type locking system for shoes, causing the ropes to pill, break, and even inconvenient to operate.

[0004] Therefore, in order to solve the above problems, a flexible, wear-resistant and strong tensile rope and its preparation process are proposed, which can not only meet the requirements of the knob-type locking system for shoes on the physical properties of the rope, but also solve the problem of insufficient flexibility of the wire rope.

[0030] (1) The present invention uses high-performance fiber filaments as the core yarn of the rope, and uses a mixture of high-performance fiber filaments and PET fiber filaments as the outer yarn of the rope, so that the core yarn of the high-performance fiber filaments can be wrapped in the middle part. The high strength and toughness of the high-performance fiber filaments can ensure that the rope made from the high-performance fiber filaments maintain a high tensile strength to meet the mechanical force stretching of the knob-type locking system for shoes. The rope is made of pure fiber, has strong bending performance, excellent flexibility, avoids pinching the feet, and can meet the physical property requirements of the knob-type locking system for shoes for the rope.

[0031] (2) The present invention utilizes a three-dimensional multi-directional weaving method of high-performance fiber filaments of outer yarn and PET fiber filaments to increase the raised friction force of the outer wall of the rope, and through the high strength, heat resistance, chemical resistance and dimensional stability of the high-performance fiber filaments, and the excellent high strength and high wear resistance of the PET fiber filaments, the outer wall of the rope is not prone to fuzzing due to friction, so that the rope is not easy to break when the shoe knob-type locking system is locked, and can resist daily wear and tear, thereby extending the service life of the rope. The woven round strip-shaped structure of the rope is highly compatible with the shoe knob-type locking system, and there is almost no resistance when the rope is pierced, making the rope replacement operation convenient.

[0032] (3) The high-performance fiber filaments and PET fiber filaments of the present invention are dyed with stock solution, so that the high-tensile ropes prepared therefrom are rich in color and meet various usage requirements. The ropes have excellent color fastness, and the high-performance fiber filaments and PET fiber filaments woven into the ropes can be recycled, which is very friendly to the environment. The prepared high-performance fiber filaments have wear-resistant and corrosion-resistant properties, and the orientation and strength of the high-performance fiber filaments are improved, thereby improving the firmness of the ropes.
