  • In general, acid dyes been used for silk dyeing, but acid dyed silk shows weakness in color fastess, To improve this defect, the silk dyed with Acid Mordant Blue 13 was treated with chromes salts solution. Some mechanical properties and dyeing behaviors of the chrome mordant with dyed silk fabric were tested in this work. The tensile strength of silk fabric treated with chrome salts solution was decreased as the duration of treatment was increased. The mean rate constant (K) of photo-degradation was 1.019, and 1.047 after treated with Cr (III) and Cr (Ⅵ), respectively, whereas it was 1.304 in untreatment. The washing fastness of silk fabric also was improved by treatment with mordant and it was 3rd-4th grade and 4th grade when silk was treated with Cr (III) and Cr (Ⅵ), respectively, while untreatment gave 1st grade. The colour of dyed silk fabric was 2.5RP.3/10, but it was 5PB.4/3 and 5PB. 4/4 when the silk fabric was treated with Cr (III) for two hours and with Cr (Ⅵ) for one hour at 90$^{\circ}C$, respectively.

  • The textile fabric have the functions of sanitation, decoration, wearing style and washing in the practical use. Among various texitle fiber, silk has less utilities than synthetic fiber in practical use although silk has good benefits of the high quality. Thus no textile fiber, neither natural nor synthetic, has all the functions. In this sence, many blend yarns have been improved various functions of fabric. However, this has been disturbed with the problem of dyeing, especially in the case of blend fabric of silk. In this study, we dyed silk/PET blend fabric in one step useing one bath dyeing method by acid dyes/disperse dyes. The results of the experiments can be summarized as follows; 1) Yellow index of silk fabric treated at $130^{\circ}C$ increased about 7.8 (color difference 4.5 NBS) and whiteness decrease about 5%. 2) Both elongation and tensile strength of silk fabric treated at $130^{\circ}C$ of pH 5-6 decreased about 10% and tensile strength of silk spun yarn treated at $60^{\circ}C$ of pH 10 have little changed. 3) While silk/PET blend frbric dyeing, silk soiling of disperse dyes causes from difference of dyeing rate and degree of silk soiling with dyes. 4) Fastness and soiling of silk/PET blend fabric dyed by one bath dyeing method of acid dyes/disperse dyes was same as two bath dyeing method.

  • The dyeings of cotton and silk fabric with Laurus tree extracts were investigated. The colorant was extracted with distilled water at $100^{\circ}C$ for lh. Dyeability(K/S), color fastness and antibacterial property of cotton and silk fabric were tested under conditions of various time, temperature, concentration, repeat-number of dyeing and mordants. The characteristics of dyeings Laurus extracts were figured out by K/S and CIELab values and color-fastness test was estimated in terms of wash fastness and light fastness. The maximum wavelength of spectrum was 670nm. The K/S value of cotton and silk fabric increased with increasing dyeing time and the exhaustion was saturated in 90min. Optical dyeing temperatures of cotton and silk fabrics were $60^{\circ}C$ and $80^{\circ}C$, respectively. The mordant effect on cotton fabric was achieved using Fe mordant. On the other hand, the mordant effect on silk fabric was obtained using Fe and Cu mordants. The wash fastness of cotton fabric was higher than that of silk fabric. Antibacterial property of silk dyeing was greater than that of cotton dyeing. In addition, the excellent antibacterial effect was imparted by Fe-post mordant method.

  • This study investigates the effects of wet and hot press treatments on the structure and mechanical properties of natural silk non-woven fabric under two post-treatment conditions: (a) hot press without wet treatment and (b) hot press with wet treatment. With respect to the fabric structure, a hot press without wet treatment does not alter the arrangement of silk filaments, while a hot press with wet treatment causes wrinkles in the fabric, and further bending of the silk filaments as the temperature is increased. With respect to the fabric mechanical properties, there is no improvement observed in the first condition, while the tensile strength of the fabric remarkably increases in the second condition when the hot press temperature is increased up to $200^{\circ}C$, indicating the crucial swelling of sericin by wet treatment to bind silk filaments. However, at a hot press temperature reaching $230^{\circ}C$, tensile strength decreases due to the molecular degradation of sericin. Moreover, hot press significantly decreases the porosity of the natural silk non-woven fabric with the wet treatment further accelerating the effect.

  • In this article, silk fabric was treated with silver nitrate ($AgNO_3$) as oxidizing agent, with conditions such as concentration, and treating time, and subsequently treated with reducing agents such as sodium boron hydride ($NaBH_4$) and sodium sulfide ($Na_2S$) to obtain cathodic coloration. After coloration of silk fabric, dyeing properties (K/S value), colorfastnesses such as wash, rubbing and light, and antibacterial activity property were examined. $AgNO_3$ treating time and reducing time did not influence K/S value, whereas the pH value at alkaline region showed a high K/S value of silk fabric. The cathodic colorations of silk fabric with both of reducing agents at $30^{\circ}C$ have excellent color fastnesses. Also the high antibacterial activities were obtained by the treatment with silver nitrate even at 1% of lower concentration.
