Numbers and measurement systems are essential in the textile industry to account for natural variations in raw materials and production. No two textile products are exactly alike due to differences in cotton fibers and the impact of human and environmental factors. Using numbering conventions allows textile manufacturers to standardize measurements, relate different qualities like thread count and thickness, calculate processes like dye amounts, and analyze machine efficiencies. Mathematical formulas and calculations are applied throughout the textile production process from raw materials to finished garments to ensure quality and optimize operations.

1. Need for Numbers in Textiles
In any manufactured product no two articles are perfectly alike, For
example, it is impossible to find two lots of yarn having exactly the
same count, strength, evenness, length etc. this is because the raw
material i.e. cotton itself varies from fibre to fibre within a bale, bale to
bale, and season to season.
Further, it is impossible to eliminate the effect of human factor entirely.
Changes in atmospheric conditions also contribute towards an increase
in overall variation in the quality of the product. These variations in
various regions are often occurring problems in textile. Using various
number system can solve these variations.

2. Conversion
Production
In Computer Color
matching
 To convert to common unit. E.g.
denier(75/150), tex, count etc.
 Engagement of one variable with other E.g.
TPI-count-TM, stitch length-wales-pacing,
etc.
 Number system has vast role to
measure the dye% by calculation.
 By using the area, volume and density of the
shapes, cross section of the fiber, density,
volume and geometry of the structure can be
analyzed.
 Efficiency, Cover factor, Speed of the machines
from gearing, weft preparation calculations in
weaving, beam requirement in warping

3.  In textile from cotton to apparel manufacturing every process is carried out
by calculations. In order to get the required quality and production
mathematical knowledge is essential especially for the management
peoples.
 Instead of going for testing the samples for identifying many numbers of
variables to arrive at the result, mathematical conversions and formulas are
used for easy calculations and time saving. These mathematical number
formulas are mostly applied in textile sampling and testing.
 In order to for a new process in the industry apart from the regular process,
mathematical applications are involved to obtain the optimum standards and
settings.
