  • The effects of monazite and fixing agents on cotton fabric dyed with Perilla frutescens var. acuta extract were investigated. The proper monazite treatment concentration, temperature and time were 10%(o.w.b.), $50^{\circ}C$ and 60minutes. By various fixing agent treatment, $FeSO_4$ showed a relatively high K/S value and the order of K/S value decreased as follows, cation surface active agents, soybean and NaCl. And the monazite and $FeSO_4$ fixing agent showed higher anion emissity than those of untreated cotton and other fixing agents. The cotton fabrics showed improved color fastness by monazite and fixing agents treatments with the exception of light fastness. And the cotton fabrics fixed with fixing agents were showed effective bacterial reduction with the exception of NaCl.

  • AKD sizing behavior of handsheets, which were prepared from the different pulps with various AKD fixing agents, was studied in this investigation. AKD sizing performance could be improved by removal of fines in the stock, minimizing damage of fiber, using a suitable fixing agent and heat treatment. Fillers with low surface energy, like calcium carbonate and talc, showed quite positive effect in AKD sizing. When PAM was added to the DIP stock as fixing agent, it showed lower sizing degree than polyamine did. But in case of NBKP system, PAM was more effective than polymine.

  • A new testing method named pitch deposit tester (PDT) was developed by KRICT in order to evaluate the deposit potential of micro-stickies. The new method involves depositing the potential pitch particles on the air bubble covered plastic film set in the pitch deposit tester (PDT) and analysing the deposited area by an image analyzer. In this study, the effect of fixing agents on potential pitch deposition was elucidated. The effects of some fixing agents (polyamine and polyethyleneimine) on pitch control were investigated by the PDT test of 100% recycled newsprint stock. The study suggested that proper use of the PEI can lead to better pitch control than that of polyamine. The efficiency of novel screening method using the PDT and retention and drainage analyser (RDA) for fixing agents in terms of retention and deposit contamination could be confirmed by above mentioned results.

  • In this study the effects of swelling and fixing agent for the cotton side of polyester/cotton blended fabrics and the thermosol temperature on the dyeing properties and fastness. were investigated, when the polyester/cotton blended fabrics were dyed with a disperse dye which was able to dye both side of fiber by one bath one step thermosol process. The obtained results are as follows; The dye adsorption decreased with the increase of cotton blend ratio in polyester/cotton blended fabrics, when the ratio of swelling and fixing agent for cotton side was constant. As the thermosol temperature increased up to $210^{\circ}C$, the dye adsorption were increased, but that effect was less significant when the cotton blend ratio was higher.

  • Treatment effect of fixing agents, that is, NaCl, FeSO$_4$, soybean milk, skim milk and two kinds of cationic surfactants, colorfastness and antimicrobial property of rotten fabrics were examined. K/S value increased with the sym-treatment by inorganic salts or cationic surfactants and the post-treatment by soybean milk and skim milk. Hwangto dyed cotton fabrics showed slight increase in colorfastness and antimicrobial property with the treatment of fixing agent.

  • To overcome troubles in strength and process of linerboard caused by raw materials, a neutral sizing which is usual in fine paper making can be considered. A new sizing agent is necessary to show good performance in a system with high conductivity and COD. In this study, fast cure type AKD was examined as a new sizing agent and compared with conventional AKD. The effects of fixing agent addition and drying condition were also investigated. Fast cure type AKD which has a higher cationicity showed better sizing degree than conventional AKD in spite of low addition level and no curing treatment. And when fixing agent of sufficient amount was added, sizing degree was improved for both AKDs. High cationicity is a crucial factor for neutral sizing of linerboard for obtaining fast and stable sizing degree. Drying with temperature over $100^{\circ}$ was desirable for developing sizing degree.

  • We dyed traditional Korean hand-made papers (Hanji) with colorants extracted from fruits of Alnus japonica to investigate the effect of various dyeing factors (mordant, dye concentration and dyeing assistant) on colors, K/S values and light fastness of the dyed Hanji. The dyed hanji had brown color. The K/S value of dyed Hanji was increased by mordanting with alum and copper acetate. $a^*$ and $b^*$ value of dyed Hanji was decreased slightly by mordanting with alum and Iron(II) chloride. The K/S value and $b^*$ of dyed Hanji increased with increasing concentration of dye, but $L^*$ value of dyed Hanji decreased. The K/S value of dyed Hanji was also increased by fixing agent. When Hanji was mordanted with Iron(II) chloride and was not mordanted, use of fixing agent resulted in greater increase of K/S value. Use of fixing agent resulted in poor light fastness. When fixing agent was used, mordanting with copper acetate resulted in smaller color difference than mordanting with alum after aging test.

  • Background: In cardiac surgery, especially in the reconstruction of vascular structures and intracardiac defects, glutaraldehyde has usually been used as the reagent for fixing porcine or bovine pericardial tissues. But the well-known problem of calcification or cytotoxicity of glutaraldehyde motivates the search for a replacement. The aim of this study is to investigate the physical, mechanical, and biochemical characteristics of bovine pericardial tissues fixed with genipin, which is known to be a less toxic and more natural fixing reagent. Materials and Methods: Bovine pericardial tissues were fixed with different concentrations and conditions of glutaraldehyde and genipin. To determine the physical, mechanical, and biochemical differences among different concentrations and conditions, we divided the tissue into 18 groups by concentration, the addition of organic solvents, and the timing of adding the organic solvents, and compared the characteristics of each group. Results: Tensile strength, physical activity, and thermal stability tests revealed that the tissues fixed with glutaraldehyde were better with regard to mechanical strength and biochemical durability. However, the difference was not significant statistically. Conclusion: Genipin can be used as an alternative crosslinking agent for pericardial tissue, considering given its physical, mechanical, biochemical characteristics and low cytotoxicity comparable to glutaraldehyde. However, further studies are needed on the immune reaction and the long term changes in genipin-fixed tissues in the human body.

  • Filler loading at thick stock was carried out in order to verify if the dual addition of filler can be used as a means to reduce the detrimental effects of filler on the strength properties of paper. PCC was added to 3.5% pulp slurry blended with HwBKP, BCTMP and SwBKP. Cationic starch was used as a fixing agent. The mixture of PCC and pulp was stirred for 5, 10 and 20min. at 1,000 rpm. The remaining PCC was washed out before handsheet making. PCC particles were flocculated and fixed on the pulp fiber and/or space between fibers. It is expected that the flocculation and inclusion of PCC can be helpful to improve the strength properties of paper due to the reduction of detrimental effect in fiber bonding. The distinct tendency in PCC flocculation and fixing on pulp fiber was not observed by the change of cationic starch dosage and treatment time.
