Trial: Technological Aspects for Designing Warp Knitted Fabrics

In healthcare area, there are many applications of textile fabrics in different area. In the rehabilitation services, textile fabrics, mainly woven fabric, have been intensively used for making rehabilitation garments such as pelvic holder, restrainer, glove and arm sling. However, the comfort properties of these rehabilitation garments are always ignored by the rehabilitation professions because the strength of fabric under stretching is an important consideration point. Therefore, a satisfactory and comfort rehabilitation garment is still a challenge. In this project, we will collaborate with rehabilitation services centre to develop rehabilitation garments with warp knitted fabrics to replace conventionally used woven fabrics. The garments would have good comfort properties when compared with conventional one. The pilot wear trial will be conducted in The Providence Garden for Rehab (Rehab) under the supervision with the staff (occupational therapist /physiotherapist) in this rehabilitation services centre. Rehab provides comprehensive rehabilitation services for different levels of people with intellectual disabilities and people with severe physical disabilities. In the parent project, we developed a software when the user input the data of (i) Fabric weight in g/m2 and (ii) Fabric thickness in mm. The values of the fabric related to softness, smoothness (face), smoothness (back) and stiffness will be provided and we also developed 10 fabrics and their comfort data can be obtained from the software for comparison. The 10 fabrics and the related comfort results had been shown to the Rehab in June 2017 and they are interested in one of the fabric based on the comfort and aesthetic properties. Fabric sample was given to Rehab and they used the fabric for making different rehabilitation products such as pelvic holder, arm sling and glove. After they made the products, they used them for preliminary trial and provided us an evaluation comments. The management of Rehab revealed that the fabric is good for replacing existing woven fabric for making rehabilitation products by means of comfort and ease of manufacturing. Another on-site visit of the Rehab was conducted in November 2017 to meet the management. The management had shown positive intention to use the fabric for replacement of existing woven fabric due to the good properties of the warp knitted fabric. They showed us tailor-made prototype with our fabric to make pelvic holder for wheelchair user. In fact, they made prototypes of pelvic holder, restrainer, glove and arm sling and gave us evaluations. They concluded that the pelvic holder will have the greater demand of using our warp knitted fabric.
