合成纖維是使用聚烯烴系合成纖維,其由鞘部為聚乙烯,芯部為聚酯的複合纖維所構成。該合成纖維為纖度2.2dtex,長度38mm的短纖維(staple)。As the synthetic fiber, a polyolefin-based synthetic fiber is used, and the synthetic fiber is composed of a composite fiber in which the sheath part is polyethylene and the core part is polyester. The synthetic fiber is a staple fiber (staple) with a fineness of 2.2 dtex and a length of 38 mm.

利用噴霧法將試驗類別1所調製的短纖維用處理劑的20%水性液被進一步稀釋而成的0.4%水性液附著於該合成纖維100g上。此時,以使固體成分附著量成為0.4質量%(不含溶劑)的方式附著於短纖維上。然後將附著有處理劑的合成纖維以80℃的熱風乾燥機乾燥1小時。A 0.4% aqueous solution obtained by further diluting the 20% aqueous solution of the treatment agent for short fibers prepared in Test Type 1 was attached to 100 g of the synthetic fibers by a spray method. At this time, it adhered to the short fibers so that the solid content adhesion amount was 0.4 mass % (solvent-free). Then, the synthetic fiber to which the treatment agent adhered was dried with a hot air dryer at 80° C. for 1 hour.

將乾燥後的合成纖維20g於溫度25℃、濕度40%的條件下,利用公知的小型滾筒式梳棉機形成梳棉網。對該梳棉網吹送約140℃的熱風10秒鐘進行熱風處理,使纖維彼此結合而製作出重量25g/m 2的不織布。 20 g of the dried synthetic fibers were formed into a card web using a well-known small drum type card under the conditions of a temperature of 25° C. and a humidity of 40%. Hot air at about 140° C. was blown on the card web for 10 seconds to perform hot air treatment, and fibers were bonded to each other to produce a nonwoven fabric having a weight of 25 g/m 2 .

試驗類別3(評價)Test Category 3 (Evaluation)

針對實施例1~28、參考例1、2及比較例1~6所記載的各處理劑,不織布的評價項目是評價撥水性。此外,製程性的評價項目是評價抗靜電性、溶液穩定性。各試驗的順序如以下所示。此外,試驗結果分別示於表1「撥水性」欄、「抗靜電性」欄、「溶液穩定性」欄。For each of the treatment agents described in Examples 1 to 28, Reference Examples 1 and 2, and Comparative Examples 1 to 6, the evaluation item of the nonwoven fabric was evaluation of water repellency. In addition, the evaluation items of processability are evaluation of antistatic property and solution stability. The sequence of each test is as follows. In addition, the test results are shown in the column of "water repellency", the column of "antistatic property", and the column of "solution stability" in Table 1, respectively.

(撥水性) 撥水性的評價是根據JIS L 1092 7.1.1 A法(低水壓法)之靜水壓法來進行。水壓測定儀是使用瑞士・TEXTEST公司製(FX3000-III)。試驗環境為溫度20±2℃、濕度65±2%RH。 (water repellency) The evaluation of water repellency was performed according to the hydrostatic pressure method of JIS L 1092 7.1.1 A method (low hydraulic pressure method). The water pressure measuring instrument was made by TEXTEST, Switzerland (FX3000-III). The test environment is a temperature of 20±2°C and a humidity of 65±2%RH.

採取5片試驗類別2所製作的不織布(約150mm×約150mm)安裝於水壓測定儀,使不織布的表面側接觸到水。以10cm/min的速度使水位上升,讀取當不織布的內側出現第3滴水滴時的顯示値(cmw.c.)。該試驗進行5次,算出5次的平均値。耐水壓越高表示撥水性越好。Five pieces of the non-woven fabric (about 150 mm×about 150 mm) produced in test category 2 were taken and attached to a hydrometer, and the surface side of the non-woven fabric was brought into contact with water. The water level was raised at a speed of 10 cm/min, and the display value (cmw.c.) when the third water drop appeared on the inner side of the non-woven fabric was read. This test was performed 5 times, and the average value of the 5 times was calculated. The higher the water pressure resistance, the better the water repellency.

其中,不織布的內側中水滴出現後不會變大之非常小的水滴,或通過相同位置而形成的水滴皆不列入計算。Among them, very small water droplets that do not become larger after the water droplets appear on the inner side of the non-woven fabric, or water droplets formed through the same position are not included in the calculation.

The voltage of the static electricity generated by the card web at the outlet of the card was measured and evaluated by the following evaluation criteria.

・抗靜電性的評價基準 ◎(良好):產生靜電的電壓未達500V 〇(尚可):產生靜電的電壓為500V以上未達1kV ×(不良):產生靜電的電壓為1kV以上 ・Evaluation criteria for antistatic properties ◎(Good): The voltage that generates static electricity is less than 500V 〇 (acceptable): The voltage that generates static electricity is more than 500V and less than 1kV × (defective): The voltage that generates static electricity is 1kV or more

(溶液穩定性) 將試驗類別1所製作的短纖維用處理劑的20%水性液進一步稀釋,製作成1%水性液。將該1%水性液置入密閉容器中,於5℃、20℃、50℃的各種溫度控制下靜置24小時。靜置24小時後,以目視觀察溶液的狀態,利用以下的評價基準進行評價。 (Solution stability) The 20% aqueous liquid of the treatment agent for short fibers produced in Test Category 1 was further diluted to prepare a 1% aqueous liquid. The 1% aqueous solution was placed in an airtight container and allowed to stand for 24 hours under various temperature controls of 5°C, 20°C, and 50°C. After standing for 24 hours, the state of the solution was visually observed and evaluated according to the following evaluation criteria.
