Abstract
Purpose
The purpose of this study is to evaluate the effect of process parameters of viscose air-jet yarns produced by the Autoairo yarn spinning machine on the physical and mechanical properties of yarns and their influence on the properties of single jersey weft knitted fabrics.
Design/methodology/approach
The yarn count in this study was 19.68 tex and the gauge of single jersey weft knitting machine was 24. The process parameters were the spinning draft, delivery speed and nozzle air pressure. The yarn samples were evaluated based on yarn irregularity and imperfections, as well as hairiness and tensile properties. The pilling, bursting strength, drape coefficient, shrinkage, air permeability and dyeability of single jersey weft knitted samples were also evaluated. The Taguchi method was used to design of experiments. Moreover, the effect of independent variables on the physical properties of the yarn was tested statistically at a 95% level of confidence using analysis of variance method.
Findings
The properties of the yarns evaluated showed that spinning draft and delivery speed can be introduced as two effective parameters on different properties of yarns. Moreover, the pilling of weft-knitted fabrics was affected by yarn parameters i.e. spinning draft and delivery speed statistically at a 95% confidence level.
Originality/value
In this experimental study, the structural characteristics of air jet yarns produced by the Autoairo11(Saurer Group) machine and the physical and mechanical properties of weft-knitted fabrics were analyzed by the authors. The literature review did not reveal any experimental work that evaluates these process parameters of yarn spinning integrated and its effect on a wide range of properties of weft-knitted fabrics.

Abstract
Purpose
The purpose of this paper is to investigate the factors that motivate the consumers in Malaysia to pay for halal logistics and its consequences on their demand for halal logistics certification.
Design/methodology/approach
Data were collected through a survey responded 313 randomly selected consumers. Partial least squares technique was employed in the analysis.
Findings
Results showed that consumers’ perception on halal logistics, their concern about halal, and media coverage have positive and significant effects on consumers’ willingness to pay for halal logistics. Furthermore, positive relationship exists between willingness to pay and the extent of demand for the halal logistics certification.
Practical implications
The findings of the study will be useful for the policy makers and managers of halal food companies because they can guide them in increasing the demand for the halal logistics.
Originality/value
Although halal logistics play a key role in supporting the halal status of any given halal foods, the demand for this service is low. Thus, this study contributes to the advancement of knowledge on the drivers of consumers’ willingness to pay for halal logistics.

This study aims to identify the effect of strawberry supplementation on some metabolic, inflammatory and oxidative parameters in adults with cardiovascular (CV) risk factors.
Abstract
Purpose
This study aims to identify the effect of strawberry supplementation on some metabolic, inflammatory and oxidative parameters in adults with cardiovascular (CV) risk factors.
Design/methodology/approach
A systematic literature search was performed up to November 2020 using PubMed, Embase, Cochrane, Web of Sciences and Scopus databases. The pooled mean difference (MD) with 95% confidence interval (CI) was used to analyze the data by random-effects model. I2 statistics and Cochrane risk of bias tool were used for investigating heterogeneity and quality of included studies, respectively.
Findings
In total, 13 randomized controlled trials with 488 participants were included. Strawberry supplementation significantly reduced diastolic blood pressure (MD = −2.1, 95% CI [−3.7, −0.42], P = 0.01), low-density lipoprotein cholesterol (−0.16, −0.30, −0.02, P = 0.03), high-sensitivity C-reactive protein (CRP) (−0.76, −1.4, −0.05, P < 0.001) and CRP (−0.31, −0.43, −0.18, P = 0.04). Leptin levels were raised in control group compared with participants who had received strawberry (0.65, 0.09 and 1.2, P = 0.02). The results of subgroup analysis based on the follow-up duration and supplementation dose showed that consumption of strawberry for more than eight weeks and 50 g day−1 can significantly decrease some other CV risk factors compared to control group. Further, both higher follow-up duration and supplementation dose were more effective in increasing leptin levels of control group compared to intervention group.
Originality/value
The use of some useful plant foods such as strawberries by the pharmaceutical industry and the community health sector can greatly help improve people’s CV and metabolic health.
