[0018] The following is in conjunction with the appendix Figure 1 This further illustrates the present invention.

[0019] The present invention discloses a method for preparing an ultra-thin woven shoe material, comprising the following steps: S1: Yarn Preparation: The weaving yarn includes high-strength polyester fiber with a breaking strength of not less than 6g / D. Using high-strength polyester fiber in weaving can improve the tensile and tear strength of the fabric without increasing its weight, enhancing its abrasion resistance and thus extending the service life of footwear products. High-strength polyester fiber can be obtained either from the market, such as from Pasmo yarn products manufactured by Teijin Corporation of Japan, or it can be produced in-house through spinning processes. The yarn fineness is 20-50D, and ultra-fine fibers are selected to ensure the lightweight texture of the fabric from the source, meeting the modern footwear material's demand for lightweight fabrics.

[0020] S2: Sizing: Sizing the warp yarns to improve their strength and abrasion resistance.

[0021] S3: Weaving: Weaving yarn into greige fabric.

[0022] S4: Finishing: The greige fabric is desized, set, and dyed to produce ultra-thin woven shoe material fabric.

[0023] Preferably, the proportion of high-strength polyester fiber in the weaving yarn is 50% to 100%.

[0024] Preferably, the weaving yarn also includes ordinary polyester fibers. By optimizing the fiber combination, the fabric can achieve ultra-thin and high-strength technical effects while reasonably controlling production costs. In addition, breathable fibers and moisture-wicking fibers can be added to improve the fabric's breathability and moisture-wicking properties, keeping the wearer dry and comfortable.

[0025] Preferably, in step S2, the sizing agent is polyacrylate, the sizing concentration is 5% to 15%, and the sizing rate is 5% to 10%.

[0026] Preferably, in step S3, a water jet loom or a rapier loom is used for weaving, and the weaving speed is 600-1000 revolutions per minute.

[0027] Preferably, in step S3, the arrangement density of warp yarns on the warp beam is 60-80 yarns / cm.

[0028] Preferably, in step S3, a plain weave is used for weaving.

[0029] Preferably, in step S4, the setting temperature is 150–180°C.

[0030] Preferably, in step S4, the dyed fabric is further waterproofed to enhance its waterproof ability, broaden the applicability of the shoe material, and make it suitable for use in different weather conditions.

[0031] Preferably, a fluorine-free waterproofing agent is used in the waterproofing treatment. The environmental characteristics of fluorine-free waterproofing agents meet international standards and are more environmentally friendly than fluorine-containing products. At the same time, this invention strictly controls environmental indicators throughout the entire manufacturing process, ensuring that the resulting fabric meets relevant environmental standards and protecting consumer health and safety. Example 1:

[0032] High-strength polyester fiber with a breaking strength of 6 g / D and ordinary polyester fiber were selected as warp and weft yarns, with the proportion of high-strength polyester fiber being 50%. The yarn fineness was 50D. The warp yarns were evenly wound onto the warp beam at an arrangement density of 60 yarns / cm. The warp yarns were sized with polyacrylate sizing agent at a concentration of 5% and a sizing rate of 5%. A water-jet loom was used at a weaving speed of 800 rpm, and a plain weave was used to obtain an ultra-thin woven fabric. The woven fabric underwent alkali desizing treatment, followed by heat setting at 180℃, dyeing with disperse dyes, and finally waterproofing treatment with a fluorine-free waterproofing agent to obtain the ultra-thin woven shoe material fabric. Testing showed that the fabric thickness was 0.16 mm, the tear strength was 32 N, and the air permeability was 20 mm / s. Example 2:

[0033] High-strength polyester fiber with a breaking strength of 6.5 g / D and ordinary polyester fiber were selected as warp and weft yarns, with the high-strength polyester fiber accounting for 80%. The yarn fineness was 30D. The warp yarns were evenly wound onto the warp beam at an arrangement density of 80 yarns / cm. The warp yarns were sized with polyacrylate sizing agent with a concentration of 12% and a sizing rate of 6%. A rapier loom was used at a weaving speed of 600 rpm, and a plain weave was used to obtain an ultra-thin woven fabric. The woven fabric was then subjected to alkali desizing treatment, followed by heat setting at 160℃, dyeing with disperse dyes, and finally waterproofing with a fluorine-free waterproofing agent to obtain the ultra-thin woven shoe material fabric. The fabric thickness was tested to be 0.13 mm, the tear strength was 28 N, and the air permeability was 30 mm / s. Example 3:

[0034] High-strength polyester fiber with a breaking strength of 6 g / D and ordinary polyester fiber were selected as warp and weft yarns, with the high-strength polyester fiber accounting for 70%. The yarn fineness was 40D. The warp yarns were evenly wound onto the warp beam at an arrangement density of 60 yarns / cm. The warp yarns were sized with polyacrylate sizing agent at a concentration of 10% and a sizing rate of 8%. A water-jet loom was used at a weaving speed of 1000 rpm, and a plain weave was used to obtain an ultra-thin woven fabric. The woven fabric was then subjected to alkali desizing treatment, followed by heat setting at 170℃, dyeing with disperse dyes, and finally waterproofing with a fluorine-free waterproofing agent to obtain the ultra-thin woven shoe material fabric. Testing showed that the fabric thickness was 0.15 mm, the tear strength was 30 N, and the air permeability was 20 mm / s. Example 4:

[0035] High-strength polyester fibers with a breaking strength of 7.2 g / D were selected as both warp and weft yarns. The yarn fineness was 20D. The warp yarns were evenly wound onto the warp beam at a density of 80 yarns / cm. The warp yarns were sized with a polyacrylate sizing agent at a concentration of 15% and a sizing rate of 10%. An air-jet loom was used at a weaving speed of 700 rpm, employing a plain weave to obtain an ultra-thin woven fabric. The woven fabric underwent alkali desizing, followed by heat setting at 150℃, dyeing with disperse dyes, and finally waterproofing with a fluorine-free waterproofing agent to produce the ultra-thin woven shoe material fabric. Testing showed that the fabric thickness was 0.10 mm, the tear strength was 35 N, and the air permeability was 40 mm / s.

[0036] Comparative Example 1: Ordinary polyester fiber (DTY 150D / 48F) with a breaking strength of 3.2 g / D was selected as both warp and weft yarns. The yarn fineness was 150D (approximately 167 dtex), and the single filament fineness was approximately 3.5 dtex. The warp yarns were wound onto a warp beam at a density of 50 yarns / cm. The warp yarns were sized using conventional PVA sizing agent with a concentration of 8% and a sizing rate of 6%. A water-jet loom was used at a weaving speed of 450 rpm, and a plain weave was employed to obtain a conventional woven fabric. The woven fabric underwent hot water desizing treatment (80–90℃), followed by heat setting at 170℃, conventional dyeing with disperse dyes (130℃), and finally waterproofing treatment with a fluorine-free waterproofing agent to obtain a conventional woven shoe material fabric. Testing showed that the fabric thickness was 0.18 mm, the tear strength was 8 N, and the air permeability was 20 mm / s.

[0037] Comparative Example 2: Medium-strength polyester fiber (FDY 75D / 72F, high F number) with a breaking strength of 4.5 g / D was selected as the yarn. The yarn fineness is 75D (approximately 83 dtex), and the monofilament fineness is approximately 1.15 dtex (relatively fine and soft). Without sizing (sizing is not required for knitting processes), it was directly woven on a weft knitting circular knitting machine at a speed of 22 rpm (standard knitting speed), using a single-sided plain knit structure to obtain the knitted fabric. The woven fabric underwent relaxation setting (setting temperature 160℃, overfeed 20%), followed by dyeing with disperse dyes (110℃, normal pressure dyeing). Finally, a softening agent (not a waterproofing agent, emphasizing hand feel) was applied for finishing to obtain the knitted shoe material fabric. Testing showed that the fabric thickness was 0.20 mm, the tear strength was 10 N, and the air permeability was 15 mm / s.
