Abstract
Purpose
The purpose of this paper is to derive a new method for the hydrophilic finishing of wool fabric.
Design/methodology/approach
A new biological catalyst, microbial transglutaminase (mTGase), was used to catalyze the grafting of ε‐poly‐L‐lysine (ε‐PLL) onto the wool fabric.
Findings
The K/S value, SEM morphology and DSC analysis proved that the grafting reaction occurred. The hydrophilic properties of the ε‐PLL‐grafted wool fabrics were studied. The results showed that the grafted ε‐PLL could increase the hydrophilicity, which was demonstrated in terms of the obvious shortening in the wetting time and the process of water absorption and moisture absorption. The grafted wool also achieved better antistatic property.
Research limitations/implications
Future work could be focused on the application of this biological method on other protein fabric which was designed to change the performance.
Originality/value
The biological approach is safe, eco‐friendly and effective relative to the conventional methods.

Abstract
Purpose
The purpose of this paper is to study a new method to appraise pressure comfort through displacement distribution, and then explore the relationship between pressure and stiffness coefficient, and elastic elongation of the top part of men’s socks using finite element method.
Design/methodology/approach
Through 3D body scanning, a biomechanical lower leg cross-section model is constructed for simulating elastic contact between human body and top part of socks. The human body is regarded as an elastomer and the contact between lower leg and top part of socks is elastic contact, displacement distribution tendency under pressure can be obtained using ANSYS, and the elastic elongation of top part of socks after putting on was calculated based on the displacement values. In this research work, the authors discuss in details with the relationship between pressure and stiffness coefficient, and elastic elongation of top part of socks.
Findings
In this research work, the mathematical equation of pressure is obtained which describe the relationship between pressure and stiffness coefficient, and elastic elongation of top part of socks. The results indicated that the predictive values of pressure show good agreement with measured ones after χ2 test. All these solutions supply a theory basis for forecasting of the clothing pressure.
Research limitations/implications
This paper is unconcerned with the simulating of pressure distribution and variation trend when dressing during the course of walking and running.
Originality/value
The paper provides a finite element simulation model of lower leg cross-section located at the top part of men’s socks, and study the relationship between pressure and stiffness coefficient, and elastic elongation of top part of socks. It can supply a new method to appraise pressure comfort.

Abstract
Purpose
Objective appraisal of pressure comfort is the basement of optimal design of clothing. The purpose of this paper is to study a new method to appraise pressure comfort through displacement distribution, and then explored the multiple relationship between pressure and displacement on the lower leg cross-section using finite element method (FEM) and curve fitting.
Design/methodology/approach
This paper presented a 2D simulation model of the lower leg cross-section consisting of three layer different mechanical properties, namely skin, soft tissue, and bone. Analyzed the relationship and variation tendency between contact pressure and strain, calculated the multiple relationship between pressure and displacement on the lower leg cross-section where located at the top part of men’s socks in detail, and then obtained the quadratic functional equation between angle and pressure/displacement ratio through segmented curve fitting using Origin 7.5 software.
Findings
In this research work, the mathematical equation is obtained which describe the relationship between angle and pressure/displacement of the top part of men’s socks. On the premise of the known contact pressure values on the lower leg cross-section, the corresponding displacement values on the human body surface can be obtained by the functional equation under stress, and this displacement could be used as an objective evaluation index for pressure comfort. Based on these conclusions, the authors could provide theoretical reference for pressure prediction and optimizing the design of clothing.
Research limitations/implications
This paper is unconcerned with the simulating of pressure, strain, and displacement distribution when dressing during the course of walking and running.
Originality/value
The paper analyzed the relationship and variation tendency between contact pressure and strain using FEM, and then obtained the quadratic functional equation between angle and pressure/displacement ratio of the top part of socks. It can supply a new method to appraise pressure comfort.

Abstract
Purpose
This review aims to present the state of the art regarding the impact of financial technology (FinTech) on financial inclusion and its implications for consumers and institutions in terms of accessibility, usage and quality. An integrated framework is developed to illustrate the primary thematic areas for future research.
Design/methodology/approach
We performed a systematic literature review (SLR) to summarize and synthesize existing research published in peer-reviewed academic journals. Forty-two eligible studies were identified from the Web of Science database and a cross-reference search.
Findings
The results suggest that FinTech promotes financial inclusion for consumers and businesses by increasing the accessibility, usage and quality of financial products. We present a multidisciplinary integrative framework that links the three dimensions of financial inclusion (i.e. access, usage and quality) to financial technology. Finally, we propose several avenues for future research.
Originality/value
To the best of the author’s knowledge, this is the first SLR on how FinTech is associated with the accessibility, usage and quality of financial products. We provide an integrative framework for understanding the topic with implications in different fields.
