To obtain silk, silkworm cocoons are boiled in hot water to kill the silkworm. (a) Smooth: Cotton is an example of a smooth fibre. It requires fertile and clayey soil that can hold moisture. True, jute is one of the cheapest natural fibres. Nylon is generally the strongest of these common materials when dry. These fibres have similar properties to cotton and tend to be used for carpets, upholstery, bags and rope. Nylon (PA) 6 & 66 are both synthetic polymers called polyamides, with the numbers describing the type and quantity of polymer chains in their chemical structure. True or false? (d) wrinkle free.

View NCERT Solutions for all chapters of Class 6. Wool is fluffy and it traps most of the air which enables wool to act as an insulator. Out of these, the two most common grades are nylon 6 and nylon-6, 6. . However, in the case of performance apparel the requirements are functional and application-specific properties, such as moisture transmission, thermal resistance, wicking, water proof, and flame resistant. a. organization b. acquisition of materials and energy c. care for their offspring d.… This site is using cookies under cookie policy.

These tension levels are not standardized between manufacturers, and do not correlate to specific diameters. Name two fibres that are used to make clothes, and two materials that are not fibres but are used to make clothes. Nylon is a man-made synthetic fiber that is strong while very light in weight, properties that lead to a wide variety of uses, such as fabric, rope and luggage.This fiber was first introduced in the 1930s as an early substitute for silk; it eventually became the fiber of choice for women's stockings. The fibres are then separated from the stem in long strands and washed in clear, running water. The availability of ASHLENE® Nylon resins extends far beyond the basic products highlighted on these pages. Properties of Plastic. Thermoplastics can be heated and shaped over and over again while thermosetting plastics can only be heated and shaped once. These days, most nylon garments consist of a blend of various fabrics. It is also possible to change the properties of a polymer by adding either stabilizers or plasticizers. Not that long ago, people stuck to the natural fibers: wool, cashmere, cotton, silk, linen, and hemp. (d) wrinkle free.
