Linyi jinling textile spinning process flow
Linyi jinling textile spinning cotton into yarn, generally through qinghua, carding cotton, and strips, roving, fine yarn and other major processes. The yarn and thread used for high grade products also need to be combed.

Linyi jinling textile production cotton yarn, different demands to adopt different processing procedures, such as spinning pure cotton yarn and polyester/cotton blended yarn, due to the use of different raw materials, all kinds of raw materials have different physical properties, and product quality requirements is different, need to adopt different production processes during processing.

(a)
Linyi jinling textile pure cotton yarn process flow

1. Combed yarn: clear flowers, combed cotton, head and neck, combined roving, fine yarn and post-processing
2. Combing yarn: clear flowers, carding cotton, premerging, strip winding, combing, head merging, second merging, third merging, roving, fine yarn, post-processing
(2) process flow of polyester/cotton blended yarn
1. Plain cotton: white flowers, carded cotton
Head - and - two - and - three - combine - roving - fine - yarn - after - processing
Polyester: clear flowers, carding cotton
2. Combed yarn:
Raw cotton: clear flowers, carding, premerging, winding and combing
Head - and - two - and - three - combine - roving - fine - yarn - after - processing
Polyester: clear flowers, carding cotton, premerging
2. Yarn product classification and variety code
(1) for the general classification of yarn products, see the following table.
Classification based on
Divide class
Different pure cotton yarn, pure chemical fiber yarn, cotton blended yarn, wool blended yarn
Different spinning methods: ring spinning yarn, air spinning yarn, electrostatic spinning yarn, etc
The spinning process is different from carded cotton yarn, combed yarn and peach yarn
Different manual twist (s twist) and reverse twist (z twist) in the twist direction
Yarns for different weaving purposes, yarns for knitting, yarns for fleece, yarns for rope, yarns for fishing nets, and yarns for curtain cloth
(2) classification of yarn thickness and fineness
The number of class Numbers in English
The coarse yarn is larger than 32tex, 18 pieces and less
20-30tex 19-29 pieces of medium size yarn
Fine yarn 9-19tex 30-60 pieces
The special number is less than 60 Tex
(3) the code number of the yarn variety is shown in the following table.
Product type code
Yarn Q for yarn T fleece
W - fired woollen yarn G
Twisted yarn R cup yarn OE
Bobbin yarn D polyester/cotton blended yarn T/C
Worsted yarn J cotton - dimensional blended yarn C/V
Yarn K for knitted jersey with photoviscose yarn FB
Yarns for combed knitwear JK matt viscose yarns FD
Note: when the yarn is expressed by code name, the general material code and processing code are written before the Tex value, and the purpose code is written after the Tex value.
3. How to indicate the thickness of yarn
1. Definitions
There are two ways to show the thickness of yarn: one is the length system (number system), that is, the weight of yarn per unit length. One is the fixed weight system, which is expressed as the length of yarn per unit weight. China's current regulations adopt fixed length system.
(1) Tex is commonly known as number, or special. At a given moisture regain rate (8.5%), a cotton yarn 1000 metres long, which weighs as much as a gram, is called a special.
Tex = x 1000 G/L
Type:
Tex -- Tex
G -- weight (G) of yarn at a constant moisture regain
L -- length of yarn sample (m)
If the cotton yarn of 1000 meters length weighs 28 grams, the cotton yarn is 28 Tex (or size).
(2) number of British cotton yarn: at the official moisture regain rate (9.89%), cotton yarn weighing 1 pound, with a length of several 840 yards, is called several cotton yarn.
Ne = L/(840 G)
Type:
Ne -- British count L -- yarn sample length (code)
G -- yarn weight (pounds) at a given moisture regain
If the length of one pound cotton yarn is 32 840 yards, the length of this cotton yarn is 32.
(3) metric count: at the time of the specified moisture return rate (8.5%), cotton yarn weighing 1000 grams, with a length of several 1000 meters, is called several cotton yarn.
Nm = L/G
Type:
Nm -- metric count G -- weight of yarn at a constant moisture regain (G)
L -- length of yarn sample (m)
D) denier: usually used to indicate the fineness of chemical fibers and natural fibers. At a given moisture regain rate, 9, 000 meters of fiber, how many grams of weight it has, is called how many Dan.
D = x 9000 G/L
Type:
D -- the denier of the fiber
G -- weight (G) of fiber at a given moisture regain
L -- length of fiber sample (m)

The wire density Tex denier den
(fixed weight system) British system of the number of metric system of the number of four, British system of conversion
1. The conversion formula of the number and the British number
Tex = 590.5/Ne or Tex = 583.1/Ne
2. Conversion formula of number and metric number
Tex = 1000 / Nm
3. Conversion formula of number and denier number
Tex = D / 9
Common measurement units are converted into 4.1 length units
Metric system: rice (m), cm (cm), mm (mm). L m =100 cm =1000 mm
British: yd, in. 1 yard =3 feet, 1 foot =12 inches.
Conversion: 1 yard =0.9144 m, 1 foot =0.3048 m, l inch =2.54 cm =25.4 mm.
One meter =1.0936 yards =3.2808 feet.
4.2 units of mass (weight)
Metric system: tons (t), kilograms (kg), grams (g). One ton is 1,000 kilograms, one kilogram is 1,000 grams, one gram is 1,000 milligrams.
British: lb, oz, gr. 1 pound =16 ounces =7000 green, 1 ounce =437.5 green.
Conversion: 1 pound =0.4536 kg =453.6 g, 1 ounce =28.35 g, 1 green =0.0648 g.
1 kilogram =2.2046 pounds,1 gram =15.432 green.
4.3 area unit
Metric system: m2 (m2), cm2 (cm2), mm2 (mm2). 1 meter 2= 10,000 cm 2=100 mm 2.
English system: code 2(yd2).
Conversion: 1 meter 2=1.196 yards 2
4.4 units of force
Metric: Newton (N), centinewton (cN). 1 Newton (N)=100 cm (cN), 1 kg force (KGF)=1000 g force (gf).
British system: pound force (LBF).
Conversion: 1 kilogram force (KGF)=9.807 newtons (N), 1 gram force (gf)=0.9807 millinewtons (cN),
1 Newton (N)=0.225 pound force (LBF).
4.5 volume unit
Metric system: rice 3, litre, ml 3. 1 meter 3=1000 liters, 1 liter =1000 ml 3.
Imperial: gallon, yard 3.
Conversion: 1 meter 3=1.308 yards 3 liters =0.22 gallons, 1 gallon =4.546 liters.
4.6 surface density units
Metric system: kg/m2 (kg/m2).
British: ounce/yard 2(oz/yd2).
Conversion: 1 kg/m 2=29.4535 ounces/yard 2.
4.7 yarn count
Unit: Tex, den, Ne and Nm.
Conversion: 1 denier (den) = Tex (Tex) x 9, and the British number Ne=590.5 / Tex (Tex).
Tex =1000/ Nm.
4.8 fabric density
Unit: metric density (root /10cm), imperial density (root /in).
Conversion: metric density (root /10cm) = imperial density (root /in) /0.254.
