Abstract
In this paper, magnetic fibers were integrated with seamless knitting technology. Additionally, the raw materials for the outer fabrics and the relevant yarn feed ratio were designed, including the polypropylene yarn with different magnetic powder contents (0%, 10% and 50%) and its yarn feed ratio (100:0, 75:25, 50:50 and 25:75) to graphene viscose yarn. In addition, weft plain stitch, 1 + 1 mock rib and 1 + 3 mock rib were adopted to weave polyamide fiber/polyurethane fiber wrap yarn as the lining materials into 12 knitted fabric samples on a seamless knitting machine according to the partial addition method in the orthogonal experimental design. As per the test and analysis results of the magnetic flux density on the front and back surfaces of 12 seamless knitted fabrics, polypropylene yarn with different magnetic powder contents in outer fabrics is the most significant factor affecting the magnetic flux density on the surface, followed by the yarn feed ratio of outer fabrics and fabric stitches. The findings in this study can provide a reference and theoretical basis for the specification design of seamless knitted fabrics manufactured by magnetic fabrics to a certain extent.
Highlights
In contemporary society, due to the accelerated pace of life, the working style of prolonged sitting, inappropriate posture and increasingly delayed sleep from over-reliance on electronic products, most people are in a condition of sub-health, in which the vitality, various functions and adaptations of the body decline to varying degrees over a certain period of time, and potential disease cannot be detected without thorough systematic medical examination [1]
The combined method of magnetic fiber yarn and seamless knitting technology was adopted to design and manufacture 12 seamless knitted fabric samples with different raw materials used for manufacturing outer fabrics, relevant yarn feed ratio and different fabric stitches
As can be seen from the above tables and figures: (1) Polypropylene yarn with different magnetic powder contents (Factor B) in outer fabrics has the most significant influence on the magnetic flux density on the surface of fabrics, followed by the yarn feed ratio of outer fabrics (Factor A) and, fabric stitches (Factor C); (2) The higher the magnetic powder content in the magnetic fiber, the better magnetic flux density of the magnetic fiber; when the yarn feed ratio is 100:0, the surface magnetic flux density of the fabric is better
Summary
Due to the accelerated pace of life, the working style of prolonged sitting, inappropriate posture and increasingly delayed sleep from over-reliance on electronic products, most people are in a condition of sub-health, in which the vitality, various functions and adaptations of the body decline to varying degrees over a certain period of time, and potential disease cannot be detected without thorough systematic medical examination [1]. The exploration of the magnetic flux density on the surface of seamless knitted fabrics manufactured with magnetic polypropylene fibers contributes to promoting the development of this kind of clothing fabric, effectively improving the sub-health condition of the human body. In this paper, combined with modern people’s demand for clothing with health care functions, the magnetic polypropylene fibers (MPFs) with different magnetic powder contents were applied to the seamless knitting field. The effects of different raw materials for outer fabrics and relevant yarn feed ratios and different stitches on the magnetic flux density on the surface of magnetic seamless knitted fabrics were explored.
