**Fiber Measurement Units:**
– Denier and tex measure linear mass density of fibers.
– Super S number indicates the fineness of wool fiber.
– Worsted count, woolen count, and cotton count are used for specific fibers.
– Yield is the reciprocal of denier and tex, expressed in yards per pound.
– Micronaire measures air permeability of cotton fiber.
– Micronaire indicates cotton fineness and maturity.
– Micron influences cotton processing.
– Micron is one millionth of a meter, used in textile fibers.
– Slivers, tops, and rovings are terms in the worsted process.
– Linear density is quantified using units like tex, denier, dtex, and ECC.

**Yarn Measurement and Calculation:**
– Linear density is presented in direct and indirect systems.
– Different yarn counts like NeK, NeL, and NeS represent specific linear density measurements.
– Denier System: 1 denier = 1 g / 9,000 m = 0.11mg/m.
– Yarn length calculation formula: /m = 1693 × /Nec × /kg.
– Defined length units: Bundle, Thread, Lea, Hank, Spyndle.
– Importance of yarn length in textile production.

**Fabric Measurement and Characteristics:**
– Fabric weight measured in GSM (grams per square meter).
– GSM is a critical parameter for textile products.
– Thicker fabric construction with higher GSM.
– Momme as a unit to measure silk fabric weight.
– Relationship between momme weight, durability, and opacity.
– Thread count measures fabric coarseness or fineness.

**Woven Fabric Parameters:**
– Ends per inch (EPI) measures warp threads per inch.
– Higher EPI indicates finer fabric.
– Picks per inch (PPI) measures weft threads per inch.
– Higher PPI signifies finer fabric.
– Courses and wales affect fabric tightness and quality.

**Fabric Air Permeability and Standards:**
– Air permeability measures air passage through fabric.
– Factors affecting air permeability include porosity and yarn characteristics.
– Air permeability standards exist for various industries.
– Air permeability is crucial for designing specific fabric types.https://en.wikipedia.org/wiki/Air_permeability
