The objective of this research was to study the feasibility for producing the dry Dioscorea hispida powder as a thickener. The product was investigated in their properties the compatibility with dye and chemicals in print paste color appearance by indicated with color hue value the time durability storage the residual substance after washing treatment and the color fastness in washing and rubbing methods. The results shown the dry Dioscorea hispida powder was used as thickener that it was the good characteristic like the famous textile printing thickener as alginate. The dry Dioscorea hispida powder thickener was 10%w/w had the equivalent viscosity as 8%w/w alginate. It had 3 days stability storage and good compatibility for direct dye reactive dye acid dye and disperse dye print pastes. The color appearances were corresponding with owned hue in color index databases. The thickener was completely in washing process. And the washing and rubbing fastness were good to excellent.

งานวิจัยนี้เรื่องการพัฒนากระดาษผักตบชวาเพื่องานบรรจุภัณฑ์ ได้แนวคิดจาการนำผักตบชวามาใช้ประโยชน์ แต่จากการศึกษาที่ผ่านมาพบว่าปริมาณเยื่อผักตบชวามีน้อยจึงมีแนวคิดที่จะเพิ่มปริมาณเยื่อด้วยวัสดุเหลือใช้จากการเกษตรเช่นสับปะรดและกล้วย การทดลองทำโดยการเตรียมเส้นใยด้วยโซเดียมไฮดรอกไซด์ปริมาณ 10 g/1 อุณหภูมิ 100 C เวลา 3 ชั่วโมง ฟอกเยื่อด้วยไฮโดรเจนเปอร์ออกไซดฺปริมาณ 5 g/1 อุณหภูมิ 90 C เวลา 30 นาที และเพิ่มคุณสมบัติด้านการกระจายเยื่อด้วยสารช่วยกระจายเยื่อ (Acramin) 5 g/1 และสารเพิ่มความแข็งแรง (น้ำถ่านกัมมันต์) 5%w/v จากการศึกษาพบว่า กระดาษที่มีคุณสมบัติเหมาะสมต่อการสำไปในงานบรรจุภัณฑ์ได้ องค์ประกอบดังนี้ ปริมาณเส้นใยฝักตบชวา 70 % เส้นใยสับปะรด 10 % เส้นใยกล้วย 20 % เพิ่ม คุณสมบัติด้านการกระจายตัวด้วย Acramin 5 g/1 เพิ่มความแข็งแรงด้วย น้ำถ่านกัมมันต์ 5 %w/v กระดาษที่ได้เที่ยมเท่าคุณสมบัติของกระดาษคราฟท์ K1 คือ ความหนา 0.537 มิลลิเมตร ความต้านทางแรงดันทะลุ 35.4 กิโลนิวตันต่อตารางเมตร ความคงทนต่อการฉีดขาด 356 มิลลินิวตัน น้ำหนัก 185 กรัมต่อตารางเมตร มีความเหมาะสมที่จะนำไปใช้งานเป็นกล่องสินค้าทั่วไป หรือกล่องสำเร็จรูป

Thickening agent is a substance when it was using to increase viscosity of an aqueous solution but other properties were not substantially modifying. it had major roles in textile printing process via adjust the print paste viscosity. transfer dye and auxiliaries into fabric. Thickening agent type starch had used in textile printing but it was a troublesome production also high cost. In this research had and feasible study to placement of dry Dioscorea hispida Dennst for textile printing processes such as direct dye and reactive dye printing on cotton woven fabric acid dye printing on nylon woven fabric and disperse dye on polyester woven fabric. The results found dry Dioscorea hispida Dennst successfully applied used as thickening agent stable time to collected as 3 days. The textile printing quality and viscosity propertied equivalent as the industrial thickener at 10% of weight print paste (owp). The steam fixation applied for direct dye and reactive dye printing at 100c for 10 minutes and gor flue fixation foracid dye and disperses dye and disperses dye printing at 150c for 5 minutes. The printed quality was good at rubbing fastness true color appearance. Theresidual paste was removed completely in washing off process.

Dye effluent treatment with photocatalytic technique and adsorption process had an objective for studying the combination process between Titanium dioxide and activated carbon from dye effluent. The dye effluents were prepared from the direct dye reactive dye acid dye disperse dye and basic dye. The effluent dyes from the completely dyeing process at 1 % owf initially. All of dye structures were azo. From the study direct dye and reactive were successfully using combination process between photocatalytic technique and adsorption process whereas disperse dye favored in adsorption process. However acid dye and basic were ignored in this experiment cause of they were a bit of dye concentration in their effluent. The optimum condition for direct dye was 10g/l Titanium dioxide for 6 hours and 5 g/l activated carbon for 6 hours continuously. Reactive dye was performed in continuous condition as 10g/l Titanium dioxide for 6 hours and 10 g/l activated carbon for 6 hours. Disperse dye was the particular process in adsorption by activated carbon 15 g/l for 4 hours. It was summarized that the treatment of photocatalytic technique and adsorption process were upon on the type of dye.

This research was concerned with the fiber separation and non-woven preparation form sugar canes leaves. The separation process was carried out by chemical pulping method at 100 degree Celsius. In order to study the suitable condition for separation process the concentration of sodium hydroxide ranging from 0 -20 grams per liter and boiling time 15 30 45 60 75 90 105 and 120 minutes were performed. Web formation process was performed by wet laid method and polyvinyl alcohol was selected as binder in web bonding process. in order to study the suitable amount of binder in bonding process concentration of polyvinyl alcohol ranging from 1 2 4 6 8 and 10 % w/v coated on web surface and cured at 120 degree Celsius. Bursting strength as well as physical properties evaluation of non-woven fabrics was performed. For antimicrobial finishing process was performed by spray method and pad method. The finishing result was evaluated by MTCC test method 147-1998 (Qualitative) and 100 -1999 (Quantitative) The result was found that appropriate condition for fiber separation was recommended as follows: the amount of sodium hydroxide of 10 grams per liter and boiling time 60 minutes. The suitable amount of polyvinyl alcohol for web bonding process was 2 % w/v. Bursting strength of non-woven fabric was 53 kN/m 3 and padding method was a suitable method for antimicrobial finishing (antimicrobial area 0.3 millimeters )
