Example Embodiment
[0036] Example 1
[0037] Soy protein sizing polyester-cotton blended yarn
[0038] (1) Preparation of soybean protein slurry:
[0039] Using soybeans as the raw material of the slurry, place it in a 0.1% sodium hydroxide solution with a protein mass percentage of 0.01% to 10%. After the mixed solution is fully stirred, heat it at 90°C for 30 minutes at a constant temperature. The pH of the slurry was adjusted to 7 to 8 with 37% hydrochloric acid, and the undissolved precipitated material was removed by centrifugation or suction filtration, and finally three concentrations (0.5%, 1%, 1.5%) of soybean protein slurry were prepared.
[0040] Polyester / cotton blended yarn is sizing with three concentrations (0.5%, 1%, 1.5%) of soy protein slurries at different temperatures (20℃, 50℃, 70℃, and 90℃), and commercial sizing materials are used. Sizing the same kind of polyester-cotton blended yarn as a control group. figure 1 Shows the difference in tensile strength between sizing and unsizi...

[0042] Soy protein sizing polyester yarn
[0043] Using soybean protein as the raw material of the slurry, place it in a 0.1% sodium hydroxide solution with a protein mass percentage of 0.01% to 10%. After the mixed solution is fully stirred, it is heated at a constant temperature of 90°C for 30 minutes. The pH of the slurry is adjusted to 7 to 8 with hydrochloric acid with a concentration of 37%, and the undissolved precipitation material is removed by centrifugation or suction filtration, and the soybean protein slurry is finally prepared.
[0044] figure 2 Demonstrated the tensile strength of polyester yarn sizing with soybean protein slurry. The tensile strength of sizing polyester yarn is higher than that of unsizing yarn, but it is lower than that of commercial sizing PVA yarn.

[0045] Example 3
[0046] The properties of wheat protein slurry
[0047] The commercially available wheat protein contains 80% of the protein and can be used for slurry preparation.
[0048] Using wheat protein as the raw material of the slurry, place it in a 0.1% sodium hydroxide solution with a protein mass percentage of 0.01% to 10%. After the mixed solution is fully stirred, it is heated at a constant temperature of 90°C for 30 minutes. The pH of the slurry is adjusted to 7 to 8 with hydrochloric acid with a concentration of 37%, and the undissolved precipitation material is removed by centrifugation or suction filtration, and finally a wheat protein slurry is prepared.
[0049] Table 1 shows the properties of polyester-cotton blended roving, polyester roving, spun yarn and fabric treated with wheat protein slurry. In Table 1, the effect of wheat protein on the stretching and wear resistance of polyester-cotton blended rovings and fabrics after sizing is similar to that of comme...
