1What is the standard commercial Moisture Regain of raw cotton fiber under standard atmospheric conditions (65% RH, 20°C / 27°C)?

A.8.5%

B.13.75%

C.0.4%

D.4.5%

Explanation: Standard commercial moisture regain is the percentage of moisture that dry textile fiber absorbs from standard atmosphere. For raw cotton, the internationally standardized commercial moisture regain value is 8.5%. For raw jute it is 13.75%, for wool 18.25%, and for polyester ~0.4%.

2What does a 'Micronaire' value measure in cotton fiber quality evaluation?

A.A combined measure of fiber fineness (linear density) and maturity based on air permeability

B.The tensile breaking strength of individual fiber bundles (Stelometer value)

C.The percentage of non-lint trash in the cotton bale

D.The degree of optical whiteness and fluorescence under UV light

Explanation: The Micronaire instrument passes air at a set pressure through a plug of cotton fibers of known mass. The flow resistance (permeability) measures specific surface area, providing an index of fiber fineness (micrograms per inch) and secondary cell-wall maturity (e.g. 3.8–4.2 is premium range for upland cotton).

3In the indirect English Cotton Count system (Ne), how is the count defined?

A.The number of 840-yard hanks of yarn that weigh exactly 1 pound (lb)

B.The weight in grams of 1,000 meters of yarn (Tex)

C.The weight in grams of 9,000 meters of yarn (Denier)

D.The number of 1,000-meter hanks that weigh 1 kilogram (Metric Count Nm)

Explanation: The English cotton count (Ne or Ncc) is an indirect yarn numbering system defined as the number of 840-yard hanks (strands) that weigh exactly one avoirdupois pound (1 lb = 453.6 g). A higher Ne value indicates a finer (thinner) yarn.

4What is the equivalent Tex count of a 30 Ne (English cotton count) yarn?

A.19.68 Tex

B.15.25 Tex

C.29.53 Tex

D.590.5 Tex

Explanation: The mathematical conversion between English cotton count (Ne) and Tex count is Tex = 590.54 / Ne. For a 30 Ne yarn: Tex = 590.54 / 30 = 19.684 Tex (or grams per kilometer).

5A continuous polyester filament yarn has a linear density of 150 Denier. What is its equivalent weight in Tex?

A.16.67 Tex

B.13.50 Tex

C.150.0 Tex

D.1350 Tex

Explanation: Denier is grams per 9,000 m, while Tex is grams per 1,000 m. Thus, Tex = Denier / 9. For 150 Denier: Tex = 150 / 9 = 16.67 Tex.

6What is the primary technological objective of the Blowroom line in a cotton spinning mill?

A.Opening compressed bales into small tufts, cleaning foreign trash, blending different cotton lots, and delivering uniform tufts to cards

B.Drawing and doubling slivers to improve parallelization

C.Inserting mechanical twist to produce yarn on ring bobbins

D.Removing short fibers below 0.5 inches via combing needles

Explanation: The blowroom sequence (automatic bale plucker, coarse cleaner, multi-mixer/blender, fine cleaner, and dedusting machine) progressively opens dense bale fiber lumps into micro-tufts, extracts seed coats, leaf trash, and dust (achieving ~40–70% cleaning efficiency), homogeneously blends cotton bales, and pneumatically delivers uniform tufts to cards.

7Why is the Carding machine historically designated as the 'Heart of Spinning'?

A.It opens fiber tufts down to individual single-fiber state, eliminates neps, removes fine trash, and forms the first continuous sliver

B.It inserts high twist to prevent roving breakage

C.It spins cotton fiber directly into finished woven fabric

D.It dyes the raw fiber in a continuous bath

Explanation: Carding (using wire-clothed cylinder and revolving flats) performs fiber-to-fiber separation into individual fibers, straightens hooked fibers, disentangles and eliminates fiber neps, extracts seed coat fragments, blends fibers longitudinally, and condenses the web into a continuous, uniform card sliver.

8In a revolving flat carding machine, what action occurs between the main Cylinder wires (wire points pointing forward) and the revolving Flats wires (wire points pointing backwards)?

A.Carding Action (point-to-point facing, with cylinder moving faster than flats)

B.Stripping Action (point-to-back facing)

C.Doffing Action

D.Combing Action

Explanation: Carding action occurs when wire points on two opposing surfaces face each other (point-to-point) with differential surface speeds. The fast-moving main cylinder wire points (1500–2000 m/min) comb past the slow-moving revolving flats wire points (0.1–0.3 m/min), opening fiber clusters into individual fibers and teasing out neps.

9What is the primary function of an Autoleveller fitted to a high-speed Draw Frame in a spinning mill?

A.To measure input/output sliver thickness variations in real time and automatically adjust the drafting speed to deliver sliver of constant linear density

B.To increase the twist per inch in the draw frame sliver

C.To lubricate the drafting rollers with oil

D.To vacuum clean the can coiler plate

Explanation: An autoleveller uses mechanical tongue-and-groove sensing rollers or optical/capacitive sensors to measure incoming sliver mass fluctuations. It dynamically adjusts the servomotor speed of the drafting rollers (open-loop or closed-loop control) to correct medium- and long-term sliver unevenness (A%), guaranteeing high count consistency in final yarn.

10What is the primary technological purpose of the Combing process in high-quality combed cotton yarn manufacturing?

A.To remove predetermined percentages of short fibers (noil, typically 12–22%), straighten remaining long fibers, and eliminate residual neps

B.To blend cotton fibers with polyester fibers

C.To wind yarn from bobbins onto paper cones

D.To size warp yarns with starch slurry

Explanation: Combing (using circular nippers, top combs, and rotating half-lap needle segments) removes short fibers below a set length as 'noil' (typically 12% to 20%), straightens fiber hooks, achieves near-perfect parallel orientation, and cleans minute neps. Combed yarns exhibit superior tensile strength, luster, softness, and low hairiness compared to carded yarns.
