Fiber :Kinds of Fiber : 1. Natural Fiber 2. Synthetic Fiber Natural Fiber : 1. Vegetable Fiber 2. Animal Fiber 1. Vegetable Fiber: Cotton , Linen , Jut etc. 2. Animal Fiber: Wool, Silk etc. Synthetic Fiber / Man Made Fiber: Viscose Rayon, Polyester, Nylon, Acrylic etc.Cotton:Cotton staple is usually between 3/8 inch and 2-1/4 inch long. For making yarn ,Cotton staple of less than ½ inch long is not for spinning into yarn. Long staple isHigh quality yarn. Short Staple is low quality yarn.Cotton is Divided into 4 groups: 1. Sea Island Cotton ( Staple length – 2-1/4 inch , Country: Island ) 2. Pima Cotton (Staple Length-1-3/4 inch , Peru & Egyptian) 3. U.S. Cotton ( Staple Length-1-1/2 inch) 4. Asian Cotton ( Staple Length-1-1/8 inch, Country- Japan, China, Pakistan, India)Characteristics of Textile Fiber: 1. Cotton : Soft, Very absorbent, Shrinks when washed , easy to crease. 2. Ramie & Linen: Compared to cotton , not soft , Less absorbent, shrinks when washed, but to a less extent, easy to crease. 3. Rayon: Compared to cotton, softer than cotton, equally absorbent, shrinks more than cotton , very easy to crease, has a luster like silk. 4. Polyester: Compared to cotton, not soft, not absorbent at all, does ton shrink in normal wash , not easy to crease.
5. Wool: Compared to cotton, not very soft, not absorbent. The staple is slightly crimpy which can lead to a bulky effect when finally made into a fabric. It shrinks seriously when washed in hot water. Not easy to crease. 6. Nylon: Can be soft or firm dependent on the finish applied, not absorbent, does not shrink when washed, not easy to crease, very strong. 7. Silk: Finer and softer than cotton , equally absorbent, shrinks more than cotton easy to crease , has a smooth surface with luster when it is made into fabric. 8. Acrylic: Not soft, not absorbent, does not shrink in normal wash. The staple is slightly crimpy which can make the final product, the fabric, bulky or beefy, not easy to crease.Yarn: 1. Spun yarn 2. Filament YarnRing Spun yarn : Spun yarn is spun by spindles it is called ring spun yarn.20/2 – 20 count 2 ply20/3 – 20 count 3 ply60 / 4 – 60 count 4 plyCarded Yarn : Without combing produced the carded yarn . Such as: 3s, 40s , 60setc.Combed yarn: Produced the yarn with combing process. Cost is high. Such as:76sRotor yarn : Produced the lower count yarn. Such as: 7s to 20s .Filament yarn: 70 Denier.OE yarn ( open end yarn) : OE yarn is spun by means by air current and not byspindles.Polyester Cotton Blended: In the trade , we call this blend, “TC”. TC stands forTetron & Cotton. Tetoron is also Called Polyester.“ TC” Fabric usually means 65% Polyester, 35% cotton, but strictly speaking itmeans 51% or more of polyester with balance in cotton.

At first weunravel a considerable no yarn form the fabric. Then we measured the total lengthof the yarn and measured the weight of that no of yarn. From these weights, wefind out the Count of the yarn.The equation we followed is as follow:Count = (N x L x 453.6 ) / ( Wt. x 36 x 840)Where,N = number of yarn in bundleL = length of yarnWt. = weight of yarn.
Another formula is the following :GSM = (Ks x Tex ) / Stitch length (mm )Where,Ks is a constant. Its value is different for different fabric structure and fabric type.Ks is calculated and estimated as below:Ks = ( GSM x Stitch length) / Tex Fabric Type Color Value of KsSingle Jersey Average 19.55Single lacoste Average 22.4Double Lacoste Average 22.75Polo pique Average 25Plain Interlock Average 39.31 x 1 Rib Average 24.51 x 1 Rib Average 26.52 x 1 Rib Average 28.3Flat back Rib - 813 Thread fleece - 40.92Yarn count numbering system : Yarn Count conversion Unit Symbols Type Constant Unit Ne, NeC, 840 Cotton Count fixed weight 1 pound NeB yards Tex TEX, T fixed length 1,000 meter 1 gram 1,000 Metric Count Nm fixed weight 1,000 gram meter 333 Metric Ticket Tkt fixed weight 1,000 gram meter Denier Td, d fixed length 9,000 meter 1 gram 300 Linen Count NeL fixed weight 1 pound yards 256 Wool Count NeW fixed weight 1 pound yards

Plain /Single/Jersey knit: People call it jersey knit . a weft knit process producing a plain , flat surfaced knitted fabric formed with a distinct face and back. Smooth side are called Face. Produced T-shirt, under-wear, sports wear etc by Single jersey fabric. 2. Interlock Fabric: A weft knit process producing a compound fabric. It is less elasticity fabric. Actually it is Double faced knitted fabric which face &
Back side looks same and smooth. Produced Polo-Shirt , T-shirt , under- wear by Interlock fabric. 3. Rib Fabric: A weft knit process producing a double faced fabric. Distinct effect looks at lengthwise and more elasticity in fabric width. Examples: 1x1 rib, 2x 1 rib, 2x 2 rib , 3x1 rib , 3 x 3 rib , 5 x 2 rib etc. Produced T- shirt, Polo-shirt by Rib fabric. 4. Fleece Fabric: One side looks like Jersey , the other side heavely brushed. 5. Flat knit: Flat knit is a weft knit fabric but do not produced tube fabric as circular knitting. Produced the knit collar , Cuff etc. 6. Yarn Dyed fabric: At first , dyeing the yarn then produced the fabric by color yarn that is called yarn dyed fabric. 7. Piece dyed fabric: when produced the fabric by Natural color yarn that is called Raw Fabric. For produced the Piece dyed fabric at first bleaching the raw fabric then dyeing .so that is called Piece dyed or Solid dyed fabric. 8. Feeder Stripe: More color yarns are used in the Feeder stripe but Repeat size will be 2 inch. 9. Engineering stripe: More color yarns are used in the Feeder stripe but Repeat size are not fixed.TC Fabric / PC Fabric Analysis: Polyester CottonWarp (TC) = 65% 35 %Weft 100% Cotton = 100% 0%Total = 165% 35%165% divided by 2 = 82.5% Polyester35 divided by 2 = 17.5% cottonTherefore, The fabric is TC 82.5% polyester , 17.5% cotton.However , if you change the weft from 100% polyester to 100% cotton, thenthis fabric is CVC. See following calculation:
Polyester CottonWarp (TC) = 65% 35 %Weft 100% Cotton = 0% 100%Total = 65% 135%65% divided by 2 = 32.5% Polyester135 divided by 2 = 67.5% cottonTherefore, The fabric is CVC 32.5% polyester , 67.5% cotton.Fabric , GSM, & Yarn Count Fabric Name Weight /GSM Yarn CountSingle Jersey 200-230 20sSingle Jersey 180-190 24sSingle Jersey 165-175 26sSingle Jersey 150/155-165 28sSingle Jersey 135-145 30sSingle Jersey 125-135 32s Fabric Name Weight / GSM Yarn CountPique 235-240 24sPique 220-225 26sPique 190-210 28sPique 180-190 30sPique 160-170 32s Fabric Name Weight / GSM Yarn CountInterlock Fabric 260-270 30sInterlock Fabric 240-250 32sInterlock Fabric 220-230 34sInterlock Fabric 200-210 36sInterlock Fabric 190-200 40s Fabric Name Weight / GSM Yarn CountRib Fabric 280-300 20s
