Description
Technical Field
The invention relates to a textile and a preparation method thereof, in particular to a woven belt and a preparation method thereof.
Background
The terylene and the chinlon are used as main varieties of the six-major-fiber and play an important role in the civil and industrial fields. Among them, polyester fibers (i.e., polyester fibers) are the largest generic class of synthetic fibers, and the yield is the top of all chemical fibers. The polyester fiber has moderate resilience, high breaking strength and elastic modulus and excellent heat setting performance. When the terylene is used as the main yarn raw material of the fabric, the fabric has good performances of resisting soap, bleaching liquor, detergent, oxidant and the like, so the terylene fabric is widely applied to the field of clothing and textile. While the polyamide fiber (i.e. polyamide fiber) attracts attention due to its excellent wear resistance, the polyamide fiber has the characteristics of high breaking strength, large elongation, and excellent fatigue resistance and rebound resilience, and thus is suitable for sports shoes, clothes, ropes, umbrellas and the like.
The shoelace is the important accessory of shoes, and the shoelace can adjust the elasticity of shoes, promotes foot fit nature, guarantees ankle security and motion performance. In the process of movement, if the shoelace is loosened frequently, the safety of a wearer is affected, and the movement rhythm is also damaged, so that the movement performance is affected, and therefore the anti-slip and anti-loosening functions are the necessary performance requirements of the shoelace. Meanwhile, the fibers used by the shoelace also need to have the characteristics of beautiful vision, comfortable hand feeling, moderate mechanical strength and elongation and the like. At present, the improvement method aiming at the antiskid property of the shoelace mainly comprises the following steps: changing the design of the outer layer structure of the shoelace, adding new material layers on the surface of the shoelace or introducing fastening devices.
Chinese patent document No. CN201733984U entitled "a friction shoelace" discloses a shoelace with anti-slip layers having anti-slip lines with high friction coefficients disposed on both sides of the shoelace to prevent the shoelace from loosening.
Chinese patent document CN109744646A entitled "anti-slip shoelace" discloses a shoelace with round anti-slip plugs, which is made of elastic material and is arranged at the left and right ends of the shoelace. Meanwhile, binding sections with the diameter smaller than that of the shoelace are respectively arranged at the left end and the right end of the shoelace close to the anti-slip plugs. The left binding section is provided with a suede formed by uniformly distributed plastic looped piles, and the right binding section is provided with a hook surface formed by uniformly distributed plastic small hooks. The binding sections at the left end and the right end are tied into bowknots and are lightly extruded, and the suede is hooked by the hook surface, so that the shoelace is prevented from loosening and sliding.
Chinese patent document CN204336001U entitled "a new shoelace" discloses a shoelace with an anti-slip layer and a reflective material layer on the outer surface of the shoelace body. This skid resistant course is the silica gel material, helps increasing shoelace frictional force to prevent that the shoelace from loosening. The reflective layer material has bright color and elegant appearance in the daytime, and the bright reflective effect can effectively enhance the identification capability of people at night or under the condition of insufficient light.
Chinese patent document CN109744647A entitled "shoelace anti-slip sheet" discloses a shoelace anti-slip sheet. The anti-slip sheet is of a rectangular plate-shaped structure, two through anti-slip sheets are arranged on the anti-slip sheet, through holes in a pair of opposite side walls gradually shrink from an opening at one end to an opening at the other end to form a cone shape, the two through holes are arranged in a mirror symmetry manner, and the axes of the two through holes are intersected to form an included angle; the inner wall of the through hole is provided with uniformly distributed anti-return sheets, and the anti-return sheets incline towards the end with the smaller opening of the through hole. After the shoelace is tied into a bow tie, the two ends of the shoelace extending out are respectively inserted into the two through holes, and then the anti-slip sheets are moved to the shoelace tying position, so that the shoelace can be effectively prevented from slipping and loosening by utilizing the anti-slip sheets on the inner walls of the through holes.
Chinese patent publication No. CN205597295U, entitled "shoelace fastening device", discloses a shoelace fastening device, which includes a fastening device body and lace passages on the body. The bottom that sets up through fastener body front end is equipped with the antiskid groove of a plurality of sawtooth and blocks the shoelace to overcome and tie up the easy loose defect of shoelace.
Chinese patent document CN110101160A entitled "an anti-slip shoelace" discloses a structural design of a neck and at least two protrusions on a first binding section and a second binding section on a flat shoelace body, and provides a shoelace which is not only easy to tie but also not easy to fall off by combining a first binding head and a second binding head structure of the shoelace.
Chinese patent publication No. CN108669706A entitled "a shoelace fabric for preventing slipping" discloses a shoelace fabric for preventing slipping, wherein rubber protrusions are arranged on the outer surface of the shoelace fabric, and fastening tapes are arranged on the outer surface of the shoelace fabric.
Above scheme all improves the roughness or the antiskid nature on shoelace surface from angles such as shoelace surface structure design, utilization plus device. Although helpful for improving the slip resistance of the shoelace, both of them will increase the weight of the shoe material to various degrees, increase the cost, and increase the process complexity in the manufacturing process, thereby preventing the practical application of the above methods in the products.
At present, the scheme for solving the problem of the slip resistance of the shoelace by a chemical modification method is rarely reported.

Selecting a shoelace woven by terylene and chinlon or blended yarns taking the terylene and the chinlon as main materials, cleaning the surface of the shoelace by taking acetone as a solvent, taking out the cleaned shoelace, and drying the shoelace in a forced air oven at 80 ℃ for later use; deionized water is filled in the water tank, the water temperature is controlled at 60 ℃, the shoelace is treated in the deionized water for 2 hours, and then the shoelace is dried in a blast oven at 80 ℃.
The shoelace loosening resistance of the above examples and comparative examples was measured by a tensile tester. In order to further clarify the improvement degree of the slip resistance, the slip resistance improvement effect is calculated by using the slip resistance increase rate, and the slip resistance increase rate calculation method is shown in the following formula 1:
taking the example 4 as an example, the shoelace was pretreated and then subjected to alkaline hydrolysis in sodium hydroxide lye of 20 ℃ with a mass fraction of 5 wt% for 5 hours, and the shoelace loosening resistance of the alkaline-hydrolyzed modified shoelace was tested after the completion of the post-treatment process, and the shoelace loosening resistance of the example 4 was 2.37 kg. While comparative example 1, which contained no sodium hydroxide as a solute, exhibited a shoelace loosening resistance of 1.78kg under the same temperature and time conditions. Compared with the comparative example 1, the increase of the slip resistance of the example 4 can reach 33.15%, and better mechanical properties are maintained. The result shows that the alkali liquor treatment method can effectively improve the slip resistance of the shoelace woven by terylene, chinlon or blended yarns taking the terylene and the chinlon as main materials, thereby achieving the aim of difficult loosening. The results of the shoelace loosening resistance and the increase in the non-slip property of the examples 2 to 10 and the comparative examples 1 to 2 are shown in Table 1.
