Description

TECHNICAL FIELD

[0001] The utility model relates to fiber twisting technology field especially relates to a rope yarn structure. BACKGROUND

[0002] In the process of rope processing, a plurality of yarns need to be combined and twisted again, and the twist of the yarn refers to the number of twists in a specified length of the yarn before untwisting. In order to make the yarn have certain physical and mechanical properties such as strength, elasticity, elongation, luster and hand feeling, the fiber can be changed by twisting, and the yarn twisting can be realized by the fiber structure. In fact, it is to use the relative angular displacement between the cross sections of the fiber to make the originally straight parallel fiber inclined to the yarn shaft to change the fiber structure. Through twisting, two or more than two single yarns or filaments inside the single yarn can be fixed into a strand, which has good forming and strength quality state and is not easy to separate when subjected to external force.

[0003] In the existing yarn processing process, the same yarns with the same composition and twist are generally used for secondary combination and twisting, and the structure is single, and the central yarn and the peripheral yarn cannot be combined and twisted with different compositions and different twists. In view of the above problems, we launch a rope yarn structure. CONTENT OF THE UTILITY MODEL

[0020] The utility model discloses a kind of rope yarn structures mainly applied to the scene of fiber twisting.

[0021] With reference to Figs. 1 to 4 A rope yarn structure comprises: a center yarn 1 and a peripheral yarn 2, the peripheral yarn 2 is arranged around the center yarn 1, and the center yarn 1 is obviously different from the peripheral yarn 2.

[0022] The composition of the center yarn 1 is the same as that of the peripheral yarn 2, but the twist is different, or the composition of the center yarn 1 is different from that of the peripheral yarn 2, but the twist is the same, or the composition and the twist of the center yarn 1 are both different from those of the peripheral yarn 2.

[0023] The composition of the center yarn 1 is greater than that of the peripheral yarn 2, or the composition of the center yarn 1 is less than that of the peripheral yarn 2.

[0024] In the above technical solution, considering that in the existing yarn processing process, generally the same composition and twist yarn is used for secondary doubling and twisting, the structure is single, and the different composition and different twist of the center yarn and the peripheral yarn cannot be realized. In order to solve such problems, the specific operation is as follows: first, select Honeywell ultra-high molecular weight polyethylene fiber SF 1600D, 3 twists or 6 doublings and twists. In the example, there are 3 twists with twist degrees of 20 n / m, 25 n / m and 30 n / m, and 6 twists with a twist degree of 25 n / m. Second, use these yarns to double as shown in Table 1. In the example, 24 SF 1600D are used, including 3 center yarns + 7 peripheral yarns * 3 = 21, and 6 center yarns + 6 peripheral yarns * 3 = 21. Third, weave the yarns of the second part into a 12-strand rope. The pitch of the rope is 95 cm. Fourth, test the strength of the rope according to GBT8834.

[0025] Example 1 : Consists of 1 center yarn and 7 peripheral yarns, the center yarn is in the middle of the peripheral yarns; the center yarn is 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 25 n / m, the peripheral yarns are 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 25 n / m.

[0026] Example 2: Consists of 1 center yarn and 7 peripheral yarns, the center yarn is in the middle of the peripheral yarns; the center yarn is 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 25 n / m, the peripheral yarns are 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 20 n / m.

[0027] Example 3: Consists of 1 center yarn and 7 peripheral yarns, the center yarn is in the middle of the peripheral yarns; the center yarn is 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 25 n / m, the peripheral yarns are 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 30 n / m.

[0028] Example 4: Consists of 1 center yarn and 6 peripheral yarns, the center yarn is in the middle of the peripheral yarns; the center yarn is 6 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 25 n / m, the peripheral yarns are 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 25 n / m.

[0029] Example 5: Consists of 1 center yarn and 6 peripheral yarns, the center yarn is in the middle of the peripheral yarns; the center yarn is 6 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 30 n / m, the peripheral yarns are 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 30 n / m.

[0030] Example 6: Consists of 1 center yarn and 6 peripheral yarns, the center yarn is in the middle of the peripheral yarns; the center yarn is 6 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 25 n / m, the peripheral yarns are 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 20 n / m.

[0031] Example 7: Consists of 1 center yarn and 6 peripheral yarns, the center yarn is in the middle of the peripheral yarns; the center yarn is 6 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 25 n / m, the peripheral yarns are 3 twisted yarns of SF1600D ultra high molecular weight polyethylene fiber, twist 30 n / m.

[0032] The breaking force of the ropes made in each example is shown in the table:

[0033]

[0034] Working principle: it can be seen that the number of fibers used by each rope is the same, but the structure of the yarn is different. The use of the same yarn in Example 1 is a common practice, but the use of different designs in Examples 2-7 significantly changes the physical and mechanical properties of the rope. The most optimal design of Example 7 can increase the breaking strength of the rope by more than 10%. The contents not described in detail in the specification are all prior art known to those skilled in the art.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. The replacement can be the replacement of part of the structure, device, method step, or the complete technical solution. According to the technical scheme and the utility model concept of the present application, equivalent replacement or change should be covered within the protection scope of the present application.
