When agglomeration occurs, it will seriously affect spinning productivity, reduce the distribution area of titanium dioxide metal fine particles on the fiber, and reduce the effect of ultraviolet shielding. In order to prevent the titanium dioxide metal fine particles from agglomerating, A dispersant such as potassium tripolyphosphate can be added when formulating the titanium dioxide metal microparticle solution. It can be known from the conventional technology that the structure and thickness of the fabric will also affect the UV shielding effect. When the tissue of the fabric is denser, that is, the lower the air permeability or the open rate, or the thicker the fabric, the better the UV shielding effect of the fabric. However, fabrics with UV shielding effects are generally required. Most of them are used in summer. If the fabric's air permeability or porosity is too low, or when the thickness is too thick, it will affect wearing comfort. According to the Australian / New Zealand AS / NZS 4399: 1996 Sun Protective Clothing-Evaluation and Classification standards regarding the UV protection factor PmtectiveFactor (hereinafter referred to as the “green”) value and the UV shielding effect, when the UPF value is 15 ~ 24, Ultraviolet shielding effect is GOOd protection. When the UPF value is 25 ~ 39, the UV shielding effect is very good. # Very Protection (Very Good protection), when the UPF value is 40 ~ 50 or 50 In the above case, it has an excellent shielding effect against ultraviolet rays (Exeellent pn. Tectin). In order to increase the comfort of the fabric when wearing, when producing the fiber with UV shielding effect in the spinning section, you can also use spinneret such as cross-shaped, γ-shaped, w-shaped special-shaped cross-sections. The fiber channel and large surface area of the surface fiber can be made into a fabric with a line effect and a perspiration effect. This fabric is especially suitable for summer leisure use. Determination of UPF value: U Australia / New Zealand AS / NZS 4399: 1996 standard measurement. 2 · Fabric opening rate measurement: The measuring method is to place the fabric under an optical microscope with a magnification of 10 to 50 times, and make the light: placed on the inside of the fabric to make the fabric in a light-transmitting state. Trauma is the opening of the fabric. Calculate the percentage of the total area of the white part of the photo to the total area of the tested fabric in the photo. This percentage is the opening rate of the fabric. 3. Measurement of yarn abrasion resistance: Rub the respected yarn at a speed of 3 mm per minute under the tension of g / denier (gm / denier) and rub it against the copper wire of 25 cm leg, and record the copper yarn. The length of the yarn passed when the thread is broken by friction. The longer the length of the yarn, the less obvious the abrasion resistance of the measured yarn. "Example" Example 1 uses an average particle size of less than 100 nanometers (nm) and a weight percentage of 0.5% and an average impurity of more than 0.3 micron (/ in) weight percentage of 0.4%. Polyester particles of inorganic titanium dioxide metal microparticles with ultraviolet reflection effect are produced at a spinning temperature of 290 ° C and a spinning speed of 3000 m / min of 577,943. P0Y (Partially Oriented Yarn) is produced. Production of DTY (Draw Textured Yarn) with UV shielding effect at different speeds. Example 2 Production of DTY with UV shielding effect. Spinning and false reed production conditions are the same as in Example 1. However, the polyester particles used are added on average. The inorganic titanium dioxide metal particles having a particle diameter of less than 100 nanometers (nm) and having ultraviolet reflection effect, the addition amount is increased to 0.9% by weight. Comparative Example 1 The production conditions for producing DTY with UV shielding effect, spinning and false twisting were the same as in Example 1, but the polyester particles used were only added with an average particle size greater than 0.3 micron (guanidine), which had an ultraviolet reflection effect. The inorganic titanium dioxide metal particles are added in an amount of 0.9% by weight. _ Comparative Example 2 The production conditions for producing DTY with UV shielding effect, spinning and false twisting are the same as in Example 1. However, the average particle size of the polyester particles used is greater than 0.3 micron. 无机 Inorganic with UV reflection effect The amount of titanium dioxide metal particles was increased to 1.6% by weight. # 12 「Evaluation results」 The ultraviolet shielding effect DTY produced by Example 1, Example 2, Comparative Example 1 and Comparative Example 2 with DTY specifications, fineness were 75 Denier, and the number was 72. Take it as warp yarn, weft system uses 75 Denier * 72 DTY, weaving 1/1 plain weave, warp density = 112 / inch weft density = 112 / pair, yard weight = 92g / m2, cloth thickness = 0. 28mm, fabric opening rate = 10.6% yarn abrasion (m) fabric UPF (° / 〇) Example 1 14276 60.6 Example 2 > 40000 66.0 Comparative Example 1 5545 36.0 Comparative Example 2 2667 66 · 0 The UV shielding effect DTY produced by Example 1, Example 2, Comparative Example 1 and Comparative Example 2 with DTY specifications, fineness of 150 denier, 144 pieces, and 22G knitted PK structure, code weight = 220g / m2, cloth thickness = L0mm, fabric opening rate = 5 picking fabric UPF (%) Example 1 114 Example 2 130 577943 Comparative example l 78 Comparative example 2 126 From the above test results It is learned that “when the fabric opening rate is larger, the ultraviolet shielding effect 2 is worse.” When the fabric opening rate is larger, using the present invention in the fiber adds: The fraction is 0.5 ~ 1.0%, the average particle size is 100 nanometers (with) UV-reflective effect, inorganic-myotitanium metal fine particles, and a fabric made of the fiber with the UV-shielding effect. The fabric line of the fabric is better than the amount of paste added; the average particle size is larger than 3 microns (_) the fabric made of titanium dioxide metal particles with a line reflection effect. And if you want to get the same average value as the fabric made of nanometer (nm) inorganic-titanium oxide metal microparticle fibers, you need to increase the average particle size to greater than 0.3 microns (_) with ultraviolet rays. The amount of inorganic titanium dioxide metal particles with a reflective effect is added, but when the amount is increased, the abrasion resistance of the yarn will be significantly deteriorated, which will cause the damage of the processing equipment wire path, resulting in a shortened service life of the processing equipment and a reduction in product quality. It is known from the fabric made of the fiber with ultraviolet shielding effect related to the present invention that when the fabric has an open porosity of 11 ° /. In the summer, its UPF is still more than 40%. Therefore, in summer, the fabric made of the fiber of the present invention not only has a good ultraviolet shielding effect to avoid skin aging, sunburn or carcinogenesis, but also has good breathability, which can increase the wear time.

The fiber with the shielding effect of the outer line accounts for 50 ~ 100% of the total weight of the fabric, and when the opening ratio of the fabric is 5 ~ m, the UPF (ultraviolet protection factor) ) More than 40%.
