Today I’m writing nigh Basic Tests of Textile Fabric, although these tests are unlike depending on buyers’ requirements & it needs a vast discussion. But I’ll verbalise over on really basic things shortly for alone garments probationers. Please piece of work on inwards hear what I wanted to tell inwards my previous writings, at that spot are hence many ways hither to perform a job, through solar daytime yesteryear solar daytime practices, you’ll disclose the easiest way for y'all to produce your chore well.
A. Tests for General Fabric Information:
Following tests are used to gain full general cloth info. See the listing below for what nosotros require know for General Fabric Testing.
1. Fiber Content Test: The examination is required to know the content or ingredient of provided fabric. Following information is required during this examination method.
- Single Fiber (A fiber contains 1 ingredient only)
- Blended Fiber (A fiber consists of to a greater extent than than 1 ingredients)
- GSM (We unremarkably count GSM for knitted fabrics; it agency Grams per Square Meter).
GSM cutter |
GSM checking machne |
- Oz (We unremarkably usage it for woven fabrics; it agency Ounce per Square Yards).
4. Threads per unit of measurement length (Used to position the knitting way)
5. Defects (Mostly used iv request organisation to position visual defects of fabric, it’s called cloth inspection).
For 4 request system, fabrics are taken equally per below tabular array for inspection yesteryear factories’ QCs (Quality Controllers). It shows the percent of fabric, a QC should create got the sum for his cloth inspection equally per cloth packing list.
Yards received equally per packing list | Percentage |
1 - 2500 | 20% |
2501 - 5000 | 10% |
5001 - 20,000 | 8% |
20,001 - 30,000 | 6 % |
30,001 - 50,000 | 4% |
Penalty points are given equally per next table. During Fabric Inspection, Influenza A virus subtype H5N1 QC needs piece of work on inwards hear that a hole on cloth unremarkably gets iv point. Maximum iv points tin live charged for 1 linear yard. Acceptance is forty points per 100 yards. Sometimes it depends on buyer’s requirement.
Formula: Total defects points / Fabric length inwards yards X 36 / Fabric Width X 100
Formula: Total defects points / Fabric length inwards yards X 36 / Fabric Width X 100
Inches | Points |
From 1 to iii inches | 1 |
Above 3 to vi inches | 2 |
Above vi to nine inches | 3 |
Above nine to 36 inches | 4 |

B. Dimensional Stability (DS):
Supposed, y'all bought a shirt from a store equally per your required size. But later washing, it became smaller or larger than your required size. Then you’ll live upset. So, to avoid this problem, cloth requires Dimensional Stability Test. Please note, below topics belongs to dimensional Stability Test.
Shrinkage % = Before Wash - After Wash / Before Wash x 100
Twisting % = After Wash Twist Measurement / Total Length x 100
Supposed, y'all bought a shirt from a store equally per your required size. But later washing, it became smaller or larger than your required size. Then you’ll live upset. So, to avoid this problem, cloth requires Dimensional Stability Test. Please note, below topics belongs to dimensional Stability Test.
- DS to Washing (shrinkage) (needs for checking measurements of garment later washing)
- DS to Dry Cleaning (needs to banking concern check measurements of garment later dry out cleaning)
- Spirality / Skew / Torque (requires to banking concern check twisted deformation of garments later dry out cleaning & washing)
- Garments Appearance later Washing / Dry Cleaning (requires to banking concern check shape of garments later wash)
Shrinkage % = Before Wash - After Wash / Before Wash x 100
Twisting % = After Wash Twist Measurement / Total Length x 100

C. Color Fastness (CF):
Color Fastness Test is undertaken to mensurate the score of fading or haemorrhage that occurs on garments amongst factors similar washing, ironing, lights, rubbing etc. Below are the primary ones that are standardized. The lite fastness of textile dye is categorized from 1 to 8 together with the launder fastness from 1 to five. Please note, the higher the set out the improve fastness is obtained.
D. Physical Characteristics:
It’s a qualitative or quantitative physical care for that consists of conclusion of 1 or to a greater extent than characteristics of a fabric, physical care for or service according to a specified procedure. It’s plainly a major purpose of cloth experiment. Following topics are done during Fabric’s Physical Characteristics Test:
1. Tensile strength (used to realize the tensility of fabric)
2. Tearing strength (used to realize the vehement strength of fabric)
3. Bursting Strength (used to realize the bursting strength of fabric)
4. Pilling resistance (used to realize the pilling resistance of fabric)
5. Abrasion resistance (used to realize the abrasion resistance of fabric)
6. Seam Slippage (In this case, a 75 mm broad cloth specimens are held inwards screw grips together with the forcefulness is measured when the seam separates yesteryear a defined distance. The force-travel diagrams of a seamed together with a seamless reference examination specimen of the same stuff are together with hence compared).
7. Recovery Test (It refers the mightiness of cloth to come upwards its master copy shape or shape later stretched)
8. Water Repellency (To detect the score of H2O repellency of H2O proof finished goods)
9. pH Value (pH is a mensurate of the acidity or basicity of an aqueous solution. The pH scale measures how acidic or basic a inwardness is. The pH scale ranges from 0 to 14. Influenza A virus subtype H5N1 pH of seven is neutral. The pH less than seven is acidic. The pH greater than seven is basic).
10. Pile Loss (This examination method covers the conclusion of the abrasion of pile fabrics when the loss of pile stuffs occur, sometimes called pile memory or pile line out).
In simply about cases, to a greater extent than basic tests are required depending on buyers’ requirements such equally flammability, create total power, harmful chemicals & heavy metallic content etc. Today I’m going to complete here. Hope, we’ll regard presently amongst more. Before leaving, delight pardon me for finding anything dull inwards my writings. Thank y'all for reading amongst patience.

- Color Fastness to Water (used to mensurate color haemorrhage or fading into water)
- Color Fastness to Rubbing (used to mensurate color haemorrhage or fading later rubbing)
- Color Fastness to Perspiration (used to mensurate color haemorrhage or fading into perspiration)
- Color Fastness to Light (used to mensurate color haemorrhage or fading into light)
- Color Fastness to Chlorine Bleach (used to mensurate color haemorrhage or fading piece chlorine bleaching)
