[0083] test

[0084] The unit surface free energy, static voltage half-life and hair adhesion amount of the fabrics prepared in Examples 1-3 and Comparative Examples 1-4 were tested, and the results are shown in Table 1;

[0085] The unit surface free energy is expressed by the hydrophobic grade of the fabrics obtained by testing Examples 1-3 and Comparative Examples 1-2 in "AATCC 22-2001 Water Repellency: Spray Test", and the results are shown in Table 1;

[0086] The static voltage half-life is tested in accordance with GB / T12703.12021 Test method for electrostatic performance of textiles Part 1: Corona charging method;

[0087] The hair adhesion amount was tested using the "T / HOMETEX 45-2024 Anti-stick Pet Hair Fabric for Home Textiles" method, and the results are shown in Table 1.

[0088] Table 1 Test results

[0089] Group Hydrophobic grade Blending ratio <![CDATA[Hair adhesion amount, roots / cm 2 > Anti-hair effect Example 1 Level 4-5 100% cotton 7 qualified Example 2 Level 4-5 80% cotton / 20% polyester 9 qualified Example 3 Level 4-5 50% cotton / 50% polyester 10 qualified Comparative Example 1 Level 4-5 40% cotton / 60% polyester 16 Failure Comparative Example 2 Level 3-4 100% cotton 18 Failure Comparative Example 3 Level 2-3 100% cotton 38 Failure Comparative Example 4 Level 0 100% cotton ＞50 Failure

[0090] As shown in Table 1, the hair adhesion amount of Example 1 (100% cotton), Example 2 (80% cotton / 20% polyester), Example 3 (50% cotton / 50% polyester), and Comparative Example 1 (40% cotton / 60% polyester) decreases with the increase of the blending ratio of polyester fiber. When the blending ratio of polyester fiber exceeds 50%, it does not have the anti-hair sticking effect. This result shows that by selecting specific raw materials to give the fabric an anti-static effect, the electrostatic adsorption of the grey cloth can be reduced, thereby improving the anti-hair sticking effect;

[0091] As shown in Table 1, the hair adhesion amount of Example 1 (hydrophobic level 4-5), Comparative Example 2 (hydrophobic level 3-4), Comparative Example 3 (hydrophobic level 2-3), and Comparative Example 4 (hydrophobic level 0) decreases with the decrease of hydrophobic level. When the hydrophobic level is lower than 4-5, there is no anti-hair sticking effect. This result shows that the low surface energy finishing can reduce the van der Waals force of the grey fabric, thereby reducing the adhesion and giving the fabric an anti-hair sticking effect.
