Washing performance of knitted soybean protein fiber fabrics

A series of experiments were carried out to investigate the washing performance of knitted soybean protein fiber(SPF) fabrics,and orthogonal testing method was adopted in the washing test design.The performance and appearance of various knitted SPF fabrics were compared after washing with different technologies.Models of washing performance and washing method optimization of knitted SPF fabrics were constructed with Fuzzy Mathematics method.A mathematic model for estimating the performance and appearance of fabrics after washing was primarily worked out with Fuzzy Model Identification.The results showed that dry-cleaning is better for knitted SPF fabrics to keep their original performance and appearance.However,slight crinkle(relaxation) phenomenon occurred at certain parts of the fabrics containing spandex after dry-cleaning.It is better to wash knitted SPF fabrics with mild strength,short cycle,and room temperature.Detergents for silk and wool and tumble drying play a positive role in keeping the original performance and appearance of knitted SPF fabrics.Fuzzy Mathematic method is suitable for conducting an objective,comprehensive and quantitative evaluation of the washing performance and washing technology of knitted SPF fabrics.
