How are fibers categorized?
Fibers are categorized into two main groups: natural fibers, which come from plants or animals (e.g., cotton, wool), and synthetic fibers, which are man-made (e.g., polyester, nylon). These categories can further be broken down based on specific properties, such as texture, strength, and flexibility.
How are fibres made?
Fibers are made by converting natural or synthetic raw materials into long, thin strands through processes like spinning or extrusion. Natural fibers, such as cotton or wool, are derived from plants or animals, while synthetic fibers are created through chemical reactions on a molecular level. The fibers are then further processed and treated to improve their properties before being used in various products.
What is the combination of two or more materials where there is no change to the materials properties?
A mixture is the combination of two or more materials where the properties of the individual materials remain unchanged. Each component retains its original characteristics and can be separated back out.
How are composites made?
Composites are typically made by combining two or more materials with different properties to create a new material with enhanced characteristics. This is often done by embedding fibers, particles, or fillers within a matrix material, such as polymers, metals, or ceramics, through processes like molding, casting, or pultrusion. The combination of materials allows composites to exhibit improved strength, stiffness, and durability compared to the individual components.
Does a mixture have one or two sets of chemical properties?
A mixture has multiple sets of chemical properties because it contains different substances with distinct characteristics. Each component of a mixture retains its individual properties, which can affect the overall behavior and properties of the mixture as a whole.
What are the two main groups that fibers fall into?
Fibers can be categorized into two main groups: natural fibers, which come from plants or animals (such as cotton, wool, and silk), and synthetic fibers, which are man-made using chemicals and include polyester, nylon, and acrylic. Each group has distinct properties and characteristics that influence their uses in various products.
Name two natural fibers with there common name?
Cotton and wool are two common natural fibers. Cotton comes from the cotton plant and is known for its softness and breathability, while wool comes from sheep and is known for its warmth and insulation properties.
What are 2 man made fibers and what are 4 natural fibers?
Two man-made fibers are polyester and nylon. Four natural fibers are cotton, wool, silk, and linen.

Is cotton stronger than silk?
Yes, cotton is stronger than silk because ithas a longer foliage resistance. hope this helps!
Are inorganic fibers natural or synthetic. name two?
Inorganic fibers are synthetic and are man-made. Two examples of inorganic fibers are fiberglass and carbon fiber.
Which properties should be examined when comparing two synthetic fibers?
When comparing two synthetic fibers, properties such as tensile strength, elasticity, abrasion resistance, and chemical resistance should be examined. Additionally, factors like moisture absorption, thermal properties, and cost should also be considered to determine the most suitable fiber for a specific application.
What is a reason for blending two or more fibers?
A reason for blending two or more fibers is to create a fabric that features the benefits of the two fabrics. For example, when blending polyester and cotton in a knit, the garment will shrink less, wrinkle less, and retain its shape better due to the polyester.
Which properties describe a rectangular prism?
The two characteristics "hexahedron" and "rectangular faces" are sufficient.

Name the process and machine that is used to turn fibers into fabrics?
GinningGinning is the method of separating the cotton fibers from the seedpods, and sometimes with the sticky seeds. This is done in the cotton field with the help of machines.SpinningSpinning is the succeeding step to ginning. This process involves the making of yarn from the cotton fiber. The cotton yarns are made of different thickness in this stage.WeavingWeaving is the most important process in the making of cotton cloth. In this process, two yarn is placed to make warp and weft of a loom which successively turn them into a cloth.
What is ment by describe two properties of?
Describing two properties of something typically means discussing two specific characteristics or attributes that define or characterize that thing. These properties can be physical, chemical, or any other relevant features that help distinguish the object in question.
