3. Introduction
Knitting
Knitting is a method of constructing fabric by interlocking the series of
loops of one or more yarns.
Types of knitting
Warp knitting
1)Tricot knit
2)Raschel knit
Weft knitting
1)Circular knitting machine
2)Flat knitting machine

4. Spacer Fabric is three dimensional Knitted Fabric
consisting of two separate knitted structures which
are joined together or kept apart by spacer yarns.

Application Of Spacer Fabrics In various Sector

9. Automotive Textile
Today’s Seat Cover Consist
Three Layers
1) Top layer – Polyester
2) Middle layer – Polyurethane
foam
3) Bottom layer- polyamide
warp knit
Disadvantage
•Toxic Gases Generates
•Polyurethane foam
absorb Heat

10. Future For Spacer In Automotive
1) Elasticity
2) Compressibility
3) Non-toxic
20 Kg per car- 45 billions cars every years

11. Meditex Application
Bandages
Construction Of Old Bandage
•Bandage in Tubular form
•Wadding foam – Sub-cushioning layer
•Elastic bandages - compression
Old Bandages Disadvantage
•Multilayer Bandages difficult to move and make limb stiff.
•Causes perspiration to patients and it makes uncomfortable.

12. 3D Compression Bandage
1)Lymphoedema – swelling of Hand and Legs starts
Operation
Lymphoedema To Limphoestatic Elefantitis – If not treated
2)Complex Physical Therapy – No Side Effect
1st Stage – Drainage
2nd Stage – Bandaging( spacer
fabric)
Limphoedema After Operation

13. Spacer Elastic Bandage Advantages
•Excellent Cushioning Effect – No need of cushioning Material
•Good elongation – 50-75 %
•Improve Physiological comfort
•Easy care Characteristics
•It can be reused
Raw Material Required
Elastane material Bio-component Yarn From Invista

16. Disadvantage Of conventional Helmet
Large Size
Cumbersome
Difficult to stow away
Machine Used For Production
 Karl Mayer RD 7 N Raschel M/c
Spacer helmet specification
Thickness = 6mm
Raw material –
Spacer yarn – Polyester monofilament
D-0.17 mm
280 dtex
Foldable
PROTEX

17. Properties
Climatic control
Air circulation
Energy Absorbing Characteristics – Pile material
Temperature Maintaining

18. Buildtex
Spacer Fabric In Reinforcement of wall
Durability – Short life
Environmental Issues - Polyurethane foam emits toxic
fumes if burned
Conventional Material – Polyurethane Foam
Polyurethane Foam Limitation

19. Spacer Fabric -
M/C – Double Bar Raschel m/c – HDR 6-7 DPLM High
performance , Double bar needle bar raschel m/c
Karl Mayer
Raw Material -
Face and back material-Alkali resistance glass fiber roving
(for Strength)
Spacer yarn - Alkali resistance glass fiber roving
Available Thickness - 20 to 160 mm
Application – Concrete plate for light weight divider wall
and House interior

20. Construction-
Reinforcement on both the side of fabric with the help of fine
concrete layer
Width – 4 mm (both side )
a- concrete layer , b- Pile yarn system

21. Pile Development in spacer for reinforcement purpose
Disadvantage of conventional spacer fabric used for Reinforcement
Irregular appearance
Reduces load bearing capacity
Irregularities caused by the distance from the
surface of concrete being too small

22. Idea Regarding Pile Yarn
Special pile Yarns Used which having low melting point.
These pile yarns are kept straight by using knitted yarn at low
temperature
After Heat treatment the pile get released
Addition of reinforcement Concrete

23. Irregular Appearance Avoided
Position Of Reinforcement defined exactly
 Load Bearing Capacity Increased
Benefits
Spacer Pile Yarn

24. Special ability & versatility can offer by spacer fabrics include the
ability to knit tow entirely different fabrics having different
properties and connect them to form a single structure.
