In this study, the damage of cotton yarn in high-speed warp knitting is studied by means of experimental analysisand finite element simulation. 60 s compact-spun cotton yarn was used as the experimental object, and experimental testswere carried out from the morphology characterization, mechanical properties, twist and hairiness index to analyze thedamage of cotton yarn during the let-off movement. The equivalent finite element model of cotton yarn was established tosimulate the force and damage of cotton yarn in let-off motion, and the experimental results were compared with each other. The damage model and cause of cotton yarn in high-speed warp knitting process can be obtained, which provides theexperimental basis and the theoretical basis for further study of cotton yarn warp knitting.

In order to study the compression property of curved three-dimensional(3D) flat-knitted spacer fabric compositesand to provide experimental data for the study of subsequent low speed impact and residual strength, 3D flat-knitted spacerfabrics were knitted into flat and curvilinear shapes, then 3D flat-knitted spacer fabric composites curved in different angleswere developed. Compression tests on various curvilinear composites were carried out using the universal material testingmachine after which stress-strain curves are compared. The results revealed that when other experimental conditions are thesame, the coursewise compression peak was significantly higher than waleswise, and compression peak also graduallyincreased with the increase of curvature, no matter the surface of 3D spacer fabric reinforced composites is flat or curvilinear. This research will lay the foundation for the further mechanical property study of curved 3D spacer fabric composites.

Investigations on influence of stitch types in single jersey knitted fabric on flammability and comfort properties arecarried out in this paper. Seven different knitted structures were developed on single jersey machine. In this study the effect ofcombinations of knit, miss and tuck stitches on comfort and flammability properties of knitted fabrics are investigated. Flammability test/properties e.g. afterglow time, char length, and weight loss % are evaluated. Several tests for thermophysiologicalcomfort i.e. air permeability, thermal resistance and absorbency are also carried out. Results obtained show thatboth comfort and flammability properties are dependent on type of stitch, pattern of stitch, location of stitch and percentage ofany stitch used in the fabrics. Moreover, fabric physical parameters also affect the flammability and comfort properties. Thefindings of this study shall work as a guide for material or textile engineers in the design and selection of fabric for apparel aswell as high performance thermal protective clothing; as a result safety and occupational health of fire fighters will beimproved.
