Then the modified polyester alkali-dissolved yarn is reduced by reduction processing, and a hole effect is formed on the cloth surface.

[0019] In this invention, the modified polyester alkali-soluble yarns are interwoven with a modified plain weave. During processing, the non-alkali-soluble yarns at the holes are easily displaced after the alkali-soluble yarns are removed, resulting in smaller holes in the fabric and improved UV resistance. The non-alkali-soluble yarns are weaved in a plain weave, which improves the fabric's abrasion resistance, pilling resistance, and fuzzing resistance.

[0020] The matte yarn containing 2.1% titanium dioxide sunscreen compound is used to improve UV protection.

[0021] In the weft direction, adjacent T400 DTY yarns at the alkali-soluble yarn section are interwoven in a plain weave pattern to reduce weft displacement after the alkali-soluble yarn is removed, preventing fraying. Utilizing the moisture-wicking properties of T400 raw material, and with the addition of a hydrophilic finishing agent during dyeing, a hydrophilic layer is formed on the fabric surface, achieving a quick-drying and moisture-wicking effect, keeping the skin dry.

[0022] The weft yarn uses modified polyester elastic yarn, which increases the three-dimensional space of the fabric, improves the breathability of the fabric, and adapts to the multi-dimensional deformation during human movement, thereby improving wearing comfort.

[0023] After the density of the yarn is reduced by alkali-soluble yarn, the holes become smaller, and the yarn's light-blocking rate increases.

[0024] The weaving process of UV-resistant, breathable, elastic woven fabric includes the following steps: warping → sizing → warping and beam joining → heddle threading / reed insertion → weaving → inspection and warehousing; among which: due to the different characteristics of the two warp yarns, warping is carried out in batches, the two warp yarns are warped and sized separately, and then the two warp yarns are joined together by beam joining; In the aforementioned warping process, the warping speed of the cotton-like polyester TASLAN is 300 m / min, and the tension coefficient is 0.14 g / D; the warping speed of the modified polyester alkali-soluble yarn is 200 m / min, and the tension coefficient is 0.14 g / D. In the sizing process, the cotton-like polyester TASLAN is sized at a speed of 180 m / min, with a concentration of 9% and a tension coefficient of 0.2-0.25 g / D.

[0025] The processing technology of the anti-ultraviolet breathable elastic woven fabric comprises the following steps: desizing and refining, AT wrinkle processing, intermediate setting, weight reduction, dyeing, post-dyeing drying, resin processing, finishing and setting, and inspection and warehousing. The temperature of the desizing and refining is 95 DEG C, and the speed is 40 m / min. The AT wrinkle processing is to make the fabric collide in disorder in a pipeline under the action of high-temperature and high-pressure airflow by using an airflow dyeing machine, so that fine wrinkles are formed. The temperature of the intermediate setting is 170 DEG C, and the speed is 40 m / min. The weight reduction is to add an appropriate amount of caustic soda to a liquid flow dyeing machine to dissolve the alkali soluble yarn on the fabric surface to form a hole effect, and the temperature of the weight reduction is 100 DEG C, and the time is 30 min. The temperature of the post-dyeing drying is 130 DEG C, and the speed is 40 m / min. The temperature of the finishing and setting is 140 DEG C, and the speed is 40 m / min.
