Major Cashmere Production Areas

The Process Of Cashmere Production And Processing Has Been Passed Down From Generation To Generation In The Himalayas Of Nepal. In Fact, China Produces More Than 70% Of The World's Cashmere, So By Far The Largest Supplier And Producer Of Cashmere Is China. In China, Inner Mongolia, Xinjiang, Tibet, Gansu, Shandong, And Liaoning Are The Main Production Areas Of Cashmere. Due To The Climate And Landform, Inner Mongolia Is The Main Area Of China, With a Large Number Of Cashmere Goats And a Strong Supply Capacity. The Center Of Modern Cashmere Production Is The Gobi Desert And The Kashmir Region, And The Origin Of This Wool Is In China.

Cashmere Value Assessment

The Three Factors That Evaluate The Value Of Cashmere Fiber Are Color, Length, And Fineness. The Fineness Is The Largest In Diameter, Only 13.0-16.0 Microns Are Considered To Be The Finest Cashmere In The International Textile Industry. Fibers Are Cast According To Their Length And Are Therefore One Of The Main Factors In Pricing.

The Rare And Precious Cashmere Is Blue Velvet And Purple Velvet, Which Only Accounts For About 30% Of The World's Production.

Cashmere From Mongolia Is Blue And Looks Like Violet Undertones.

And 35mm-37mm Is The Calculated Length Of White Cashmere And Blue Cashmere, While The Quality Of Purple Cashmere Is Between 13-15 Microns.

The Blue Velvet Produced In Central And West Asian Countries Such As Afghanistan, Iran, And Kazakhstan Is Small To Dark In Color And Not Very Smooth In Texture.

The Smallest Diameter Of Cashmere Produced In China Is 13-15 Microns, And More Than 40% Of White Cashmere Is Produced In China Every Year.


Cashmere Fiber Production Process

Before Introducing The Cashmere Production Process, We Need To Know Where The Cashmere Is In The Goat. In Theory, Any Animal Can Grow Cashmere-Grade Hair, But Its Quality And Climate Conditions Have a Very Important Impact. That's Why We Find Our Finest Cashmere In Extremely Cold, High-Altitude Climates Like Mongolia. Goats Naturally Grow Two Coats Of Hair For Themselves, a Coarse Coat And a Softer Undercoat (Undercoat), With Cashmere Being The Innermost Coat.

Combed Or Sheared

Goats Generally Molt In April, So Between May And June Herders Collect The Cashmere From Goats, Which Are Carefully Hand-Combed Or Sheared.


Sorting Cashmere

Artisans Manually Sort Each Fiber According To Color Origin And Fineness.


Cleaning Cashmere

The Sorted Cashmere Is Washed To Remove Grease, Dirt, Straw, And Other Impurities. The Process Includes Washing And Drying. The Washing Process Provides a Critical Initial Wash Of The Fibers. Washing Conditions For Finer Kinds Of Cashmere Require More Control Than Regular Wools. Care Must Be Taken Not To Damage The Luster Of The Cashmere Through Strict Control Of Water Flow, Temperature, Ph, And The Proper Type And Amount Of Detergent. Mistakes In The Washing Process Can Reduce The Quality Of The Fiber And Its Ability To Hold Dye. Every Stage In The Washing Process And Subsequent Drying Process Is Controlled To Ensure No Residue Is Left And The Right Amount Of Natural Oils Are Retained In The Fibers During This Process, About 15-20% Of The Original Mass Is Removed.


Comb Hair Removal

The Process In Which The Cleaned Cashmere Fibers Pass Through a Coarse Wool Machine To Separate The Coarse Protective Layer From The Fine Wool Fibers Is Called Depilation. The Mechanical Carding Process Uses The Difference In Friction Between These Fibers To Separate The Two. The Fibers Will Be Individually Combed Into Straight Lines And Segmented According To Their Fineness And Thickness. In Addition To Separating The Fibers, The Process Goes a Step Further To Remove Any Impurities That May Remain In The Cashmere.

After Multiple Combings, The Fibers Are Separated, Untangled, And Dried For a Fluffy Appearance.


Spinning

The Segmented Fiber Is Fed Into The Spinning Machine, And The Wool Fiber Is Twisted Into Yarn. The Textile Industry Produces Yarn Products In Finer And Coarser Designs.

Spinning Fibers Into Yarn

Spinning Involves Twisting Cashmere Fibers To Obtain a More Durable Continuous Yarn, Transforming The Fibers Into Fine, Smooth, Compact Yarns.


Spinning Can Generally Be Divided Into Three Types


1. Worsted (Long Fiber):

Fibers Are Carded During Spinning To Remove Air Spaces And Apply More Twist, Resulting In a Fine, Smooth, Durable Yarn. This Method Is Mostly Used For High-Quality Fine Gauge Knitwear And Summer-Weight Scarves.


2. Wool Spinning (Medium-Length Fiber):

Fibers Are Not Combed During Spinning But Are Slightly Twisted. This Gives Soft, Towering Lines. This Method Is Mainly Used For Knitwear And Winter Scarves.


3. Semi-Worsted (Short Fiber): This Is The Lowest-Cost Spinning Method. It Can Spin Short, Thick Fibers Into Yarn. This Method Is Mainly Used For Thinner, Lower-Quality Knitwear And Lighter-Weight Summer Scarves.


Dyeing

Aged Yarn Will Be Cleaned And Dyes Can Be Applied At This Stage. Like Other Yarns, Cashmeren To Suit a Variety Of Colors, But Some Important Softness Is Lost After This Treatment. So If You Want The Softest Items, Natural Undyed Colors Are Best. But Most Buyers Still Want To Have Their Cashmere Products Garment Dyed.


Three Processes Of Dyeing


1. Fiber Dyeing:

We Dye Carded Cashmere Before Weaving For Best Results - The Preferred Method.


2. Yarn Dyeing:

This Involves Dyeing Raw Wool Spools After Spinning.


3. Piece Dyeing:

This Is Usually The Lowest-Cost Technique. The Product Is Woven (Or Knitted) In Its Natural Color And Then Dyed In Different Colors.

To Weave

The Warp Yarns Are Pulled Up Through The Loom, And The Weft Yarns Are Inserted Into The Desired Design, Which Is The Weaving Process At Work. Our Manufacturer Weaves Cashmere Fiber Yarns Into Consumer Items Such As Scarves, Shawls, Vests, And Sweaters, Using Yarns Of Different Thicknesses By Increasing Or Decreasing The Density Of The Threads.


Finishing

The Fabric Is Then Sent To a Finishing Process That Includes The Following Steps:


Brush Teeth:A Rotating Cylinder Wrapped With Steel Cloth Brushes The Cashmere Fabric To Produce Fluff On Its Surface.


Enrichment:This Involves Two Procedures, Scouring (Washing) And Milling (Thickening).

The Main Function Of Milling Is To Thicken The Fabric By Tangling The Cashmere Fibers Together To Give It Strength And Increase Water Resistance (Felting). This Is Essential For Wool Scarves. Cashmere Felting Occurs When Mechanical Agitation Causes The Tiny Barbs On The Surface Of The Cashmere Fibers To Hook Together.


Drying:8 Hours After Napping, Wet Fabric Passes Through The Drying Center.

Tease: Only Suitable For Fabrics That Need a Water Wave Effect. We Use This Process To Make More Luxury Scarves.

Shearing: Cut The Long Fibers On The Surface Of The Fabric To Keep The Height Constant, So That The Final Fabric Has a Smooth And Flat Effect.

Steam Setting: This Improves Color Fastness And Prevents Shrinkage Later. Brush The Fabric Again For a Smooth, Clean Surface.


To Cut

For Scarves Or Shawls, The Fabric Will Run Through a Cutting Machine, Which Will Cut It To The Correct Size And Cross-Cut It At The Edge Of The Fringe.


Labels And Marks

All Labeling Requirements Are Added At This Stage. Brand Label, Hang Tag, And Care Information.


Final Test

We Conduct Different Inspections According To The Manufacturing Process.


Package

After Branding And Packaging, It Is Ready For Sale, Which Is The Last Process Of Bringing The Product To The Market.
