Silk By: Amy Curtis & Sarah Bennett Production/Manufacturing/Processing Techniques • Sericulture ▫ Cultivation of cocoons for the filaments ▫ Best raw silk obtained from Bombyx Mori (moth) ▫ Silkworms hatched up to 3 times a year ▫ 350 to 400 eggs in lifetime ▫ Subject to hereditary infection, eggs destroyed which results in fine silk production ▫ Begin to shape into cocoons ▫ Substance solidifies and filament formed • Filature Operations ▫ Raw silk unwound from cocoons and collected into skeins in Filature Factories ▫ Cocoons sorted based on color, size, shape, and texture ▫ Hot and cold water so filament can be unwound ▫ “Reeling” is unwinding filament from the cocoon Production/Manufacturing/Processing Techniques • Manufacturing ▫ Reeled silk formed into silk yarn. “Throwing” ▫ Strands twisted and put through rollers ▫ “Degumming” Yarn washed with soap to bring out natural shine • Finishing ▫ Calendering and Cireing Enhance luster ▫ Singeing Smooth ▫ Steaming Raising pile weaves ▫ Pressing and Lustering Removes wrinkles ▫ Weighting Weight lost during demugging Dyeing process Crispness Characteristics • It is versatile and very comfortable. • It absorbs moisture. • It is cool to wear in the summer yet warm to wear in winter. • It can be easily dyed. • It retains its shape and is relatively smooth. • It has a poor resistance to sunlight exposure. • It is the strongest natural fiber and is lustrous Uses for the end fabrics • • • • • • • • • blouses dresses scarves pants ties curtains draperies cushion covers sofa covers Advantages • Natural Protein Structure ▫ Hypoallergenic fabric • All-climate fabric ▫ Warm and cozy in winter ▫ Cool in hot weather ▫ Natural temperature regulating properties ▫ Outperforms other fabrics in summer and winter • Not bulky • Highly absorbent ▫ Can absorb 30% its weight in moisture ▫ Will let skin breathe • Mixes well with animal and vegetable fibers • Smooth surface resists soil and odors • Wrinkle and tear resistant • Dries quickly • Strongest natural fiber • Strong like steel yarn in strength • Takes color well • Washes easily • Good for ▫ ▫ ▫ ▫ Spinning Weaving Knitting Sewing Disadvantages • • • • • Expensive Leaves water spots Yellows with age Needs special care Dry cleaning Fiber Drape Abilities • Good Drape Properties ▫ ▫ ▫ ▫ Silk flexible enough Drapes well Tailors well Thin Fiber Care • Dry Cleaned: make sure you tell them that it is made of silk • Hand wash: 1) Make sure you wash in cool water. 2) Use a small amount of soap or mild detergent to wash the silk. 3) After washing it, rinse in cold water. 4) Hang it or lay it flat in a shaded area to dry. 5) If pressing is needed, use an all cotton iron board cover, a low or moderate steam setting, and press on the wrong side of the fabric while ironing.
