Finishing Flashcards
1
Q
What 4 factors of a fabric can optimise the finishing of a fabric?
A
- fibre contents
- fabric sett
- surface of fabric
- selection of appropriate finish
2
Q
What is union cloth?
A
A cloth where the warp and weft have different fibre content from each other
3
Q
What are 4 advantages of union cloth?
A
- can improve fabric performance
- can improve visual/tactile qualities
- reduce cost
- enables cross dying and other finishing treatments to be done
4
Q
What factors influence the surface of a fabric? (4)
A
- fibres/yarns use
- weave structure
- yarn count and density
- finishing process
5
Q
How can you improve a fabrics lustre?
A
- pressure (calendaring, flattening surface)
- singeing (burning off surface fibres to give sheen)
- surface coating (pressing then coating with wax)
6
Q
How can you improve a fabrics stretch?
A
- use elastomeric weft yarns
- use a crepe structure
- apply chemical finish
- apply mechanical finish
7
Q
What factors does pressing a fabric affect? (4)
A
- weight
- structure
- fibre content
- surface finish
8
Q
How is a napped/raised surface created?
A
Surface fibres are raised then brushed
9
Q
How can you achieve an uneven surface on fabric? (4)
A
- vary yarn thickness
- novelty yarns
- vary structure
- vary fibre content to promote shrinkage in places
