การใช้ประโยชน์จากเส้นใยของเปลือกและลำต้นหอมแดงเพื่อผลิตกระดาษและบรรจุภัณฑ์

Abstract

Objectives of research were to 1) study shallots skin and shallots tree as raw materials for pulp production 2) study the properties of pulp from study shallots skin and shallots tree 3) study types of suitable substances to increase the properties of pulp from study shallots skin and shallots tree and 4) design and manufacture of packaging made from pulp made study shallots skin and shallots tree. We found that using 14% H2O2 in pulping resulted in paper having the highest lightness value (L*=61.15). All papers approached red and yellow by boiling with 14% NaOH, the paper was approaching the highest red (a*=7.27) and pulping with 14% H2O2 gave the paper the highest yellow approach (b*= 19.33). By using both NaOH and H2O2 to boil the pulp, when forming two rounds, each round of paper was colored differently in all conditions. But at the lowest percentage difference of L * (0.60%) was boiled with 14% NaOH, the lowest difference a* value (0.43%) when boiled with 14% H2O2 and the lowest difference of b* value when boiled with 8% H2O2. The paper had the highest tear resistance when mixed with 75% pulp was 3,181 gram-force meters with a thickness of 214 microns. In addition, using chitosan solution mixed with shallots skin and shallots tree pulp in paper forming, the paper had excellent water resistance properties and water droplets cannot penetrate the paper. Three packaging prototypes were designed using weaving techniques. The sample of 30 people, it was found that the mean total satisfaction was 3.57 at a high level. This was the most satisfied overall with the third prototype cushions, which were made from 100% shallots skin and tree paper. Knowledge transfer to target groups found that members community enterprise responded to a questionnaire of 20 people, overall satisfaction with the highest level of participation in activities. With an average of 4.52
