    Keywords : Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

    Abstract : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. READ MORE

  3. 2. 3D Knit fabrics : optimizing spacer knit fabrics for comfort and breathability in infant products

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Julia Svensson; Hanna Halldorf; [2023]
    Keywords : Spacer fabric; knitting; warp knit; circular knit; textile testing; ProCad Warpknit; infant product; comfort; mechanical properties.;

    Abstract : In this study we looked into an existing textile baby stroller seat and investigated whether there can be any advantage in changing the material to a spacer fabric from perspectives such as functionality, comfort, and sustainability. The subject of 3D knitting, and advanced knitting is being researched more and more because of its versatility in producing and changing parameters of knitted high quality products, but there is a lack of studies done on comfort for children when it comes to knitted spacer fabrics and not many studies have been done on spacer fabrics used for baby seats in strollers or other types of seats for children.
