The towel case made of wicker treated in the following four steps is deformed, cracked during use, has a strong skin-friendly feeling, has an increased load bearing capacity, has good dimensional stability, which can effectively prevent the wicker peeling. Gradually recovered, the strength is increased by 2-3% compared to the original strength, the treated wicker has a good antiseptic effect, the wicker softening effect is good, it is less likely to be damaged by mold during use. The wickers treated by the present invention are wholesale After the knitted product, it can be up to 8 years without moldy, moth-eaten, maintain the original color for a long time.

1. Place the wicker in an environment with a humidity of 65-68%, a temperature of 8-10°C, a dark environment for 48 hours. When it is placed for the 20th hour, it will be given 4 hours of light at the same time. When it is placed for the 40th hour, At the same time, the second light is given for 5 hours, the intensity of the two light is 800 lux; through this treatment, the toughness tightness of the wicker fiber can be greatly improved, the wicker can be effectively prevented peeling, the wicker can be prevented breaking cracking during weaving;

2. Immerse the treated wicker in warm water at 38-40℃ for 2-4 hours, take it out, cool it to room temperature naturally, then refrigerate it at 1℃ for 6 hours; it can keep the original color of the wicker improve the original color of the surface of the wicker stability;

3. Dissolve chitosan in a saturated carbon dioxide aqueous solution at 25°C so that the mass concentration of chitosan reaches 0.4-0.6% to obtain mixed solution A. Put the above-mentioned treated wicker into mixed solution A at normal temperature pressure Soak for 4-6 hours in the medium, then gradually heat the mixed solution A to 40°C at a rate of 1°C/5min keep it for 20 minutes, then take out the wicker let it drain naturally; it can further soften the wicker greatly improve the wicker Insect-proof antiseptic effect;

4. Use low temperature plasma generated by atmospheric pressure dielectric barrier discharge to process the wicker. The time for low temperature plasma to process the wicker is 25-30 seconds. The power source of the dielectric barrier discharge is a high frequency high voltage power source with a frequency of 3kHz-4kHz a voltage range. It is 4kV-5kV; its treatment can greatly improve the dimensional stability of the wicker, the average bending strength is increased by 41.5%, the cracking rate is greatly reduced, it is easier to form, the processing process saves time effort
