Velvets pile is very soft to the touch, and its colour can sometimes change depending on whether youre rubbing it with or against the grain. Stretch and Elasticity: To define properties of silk we need to define its physical and chemical properties. Tactile characteristics refer to the changes in surface contour that result from a mechanical force exerted on or against the surface structure. Its burn slowly when contact with flame. longitudinal view - Rough surface. Recovery from stretch is 90% when extension is up to 2%. It also can be simply clean by delicate soaps and cleansing.

Modal fabric is cheaper than silk, but it's slightly more expensive than viscose rayon and roughly equal to the cost of cotton and lyocell. If the silk material is stretched excessively, the silk polymers will slide past each other. The effects of the treatment were investigated on the basis of the X-ray diffraction, DSC thermogram, moisture regain, water absorption, dyeing property, and mechanical property of the . The burning temperature of silk is about 300 ~ 400 , which is a flame-retardant fiber, while the burning temperature of synthetic fiber is mostly 200 ~ 250 , which is easy to melt and burn, and it will also produce harmful gases. besides, dilute acids do not attack silk under mild conditions. Silk is extraordinarily versatile and it spreads of materials from sheer chiffons to significant stunning brocades and velvets.

The silk samples were treated by air, air/Ar and air/O 2 plasma at atmospheric-pressure to modify their physical-morphological and chemical properties for pigment ink-jet printing. Silk fiber is flexible enough and if silk fiber is used to make garments, then the fabric drapes well and this is why it can be tailored well too. Silk fibres are smooth and straight, unlike wool, for example, which has a scaliness youll see if you put it under a microscope. This is exemplified when a consumer handles a fabric and refers to the fabric with adjectives such as stiff, soft, hand, etc. Resiliency: Wool is highly resilient and comes to its original shape when hanged after wrinkled or created.

When silk fibre is kept in boiled water for a short period of time, it does not show any type of effect of boiled water. The attack of oxidizing agents may take place in three possible points of the protein 1. Tensile Strength: Cotton is a strong fiber. However, prolonged exposure would result in peptide bond hydrolysis, resulting in a polymer degradation and complete destruction of the silk polymer. Absorbency. Strength is one of the most interesting characteristics of silk. Physical properties are the static physical dimensions of fabric. Silk fiber length varies from 400 to 700 meters. Thanks to its low physical phenomenon for weather wear, also in furnishing silk that commonly intermingled with alternative fibres to feature soft luster for furnishing cloth.

The structure of this silk is composed of amino acids linked together in a long chain. The absorbency of the . Changes which disintegrate the fabric are durability characteristics. A single yarn has high strength. Silk fabrics were treated with chlorosulphonic acid in pyridine for different times. Silk fabrics were cut into a circle diameter of 2.5 cm and cleaned before the coating using ethyl alcohol for 30 min in an ultrasonic bath; after that, washed them with distilled water before drying in an oven at 45C. 8. 3. The existing peptide bonds, salt linkages and hydrogen bonds of the silk polymer system tend to break down once the temperature exceeds 100C. This allows manufacturing of structures such as (among others) holographic gratings, phase masks, beam diffusers and photonic crystals out of a pure protein film.
