In the today competitive world, it is very important to provide quality and flexible products at the right time to design an effective supply chain and have long-term partnerships. Also, the close relationship between the buyer and supplier is known as a factor in the success of the supply chain. Therefore, in this paper, a real-case supplier selection problem is studied using a hybrid fuzzy multi-criteria decision-making approach and in a group decision-making setting. Also, a set of important criteria in the global sourcing of textile industry is comprehensively provided. In other words, through the questionnaire, the weight of the important criteria associated with the process of selecting a global supplier in the garment industry is obtained. Then, an integrated approach to the analytical hierarchy process is used with a fuzzy group decision-making and fuzzy TOPSIS that is based on order preference by similarity to ideal solution. Finally, a numerical study is carried out to select international suppliers in the textile and clothing industry to show model applicability.

Personal protective equipment (PPE) can protect various parts of the body such as eyes and face, head, feet, legs, hands and arms. Fortunately, nowadays there are many effective tools available to protect humans against these risks, including protective clothing and vests, masks, hats, shoes, gloves and many other protective equipment. Textiles are an inseparable part of protective equipment, which has been highly considered due to their special influence on the structure and function of protective equipment. The human hand is one of the most complex parts of the human body and is usually used more often during activities. Therefore, special attention should be paid to protect hands, especially at work. One way to protect hands is to use protective gloves. In the present paper, we introduce a variety of protective gloves, the necessity of using them and investigating the factors affecting the comfort, performance and effectiveness of protective gloves. Although wearing protective gloves reduces injuries, but some problems arise such as the reduction of sensitivity of the touch, the power and strength of the hand, the movement range of fingers, the speed of action, and the skill of performing activities with hands which leads to wearer's discomfort and difficulty in doing the job. This article discusses the above issues.

There are several techniques which can be used in order to produce high quality coatings from functional materials on the surface of textiles. Besides, there are some cutting edge technologies that can make functional coatings on textiles that are unknown until know in textile processing. Decreasing to nanometer scale is one of the most important directions in science and technology over the last decades. This trend has a big potential to use in the field of textile finishing. This paper discusses some cutting edge technologies that have a big potential to make a big change in the field of textile finishing in the near future using nanotechnology. These techniques add desired functionalities with minimum effect on the handle, feel, strength and breathability of textiles. These cutting edge deposition techniques include layer by layer deposition, atomic layer deposition, Physical vapor deposition and chemical vapor deposition techniques. Since the development in these areas continues very fast, they will extensively be used to produce interactive and smart textiles in the near future.

Nowadays, the carpet industry has found a good position among other industries. Customers are seeking for carpewith a variety of designs and colors which pushes the market for more production. This entails a better and fastproduction method with even lower cost. Maintaining the high quality of the fnal while increasing the speed production is of great importance. Beneftting from machine vision systems is a practical method that can be used ffaster quality control, evaluation of the appearance of carpets, mapping and computerizing the design of handmadcarpets , and other aspects in the carpet industry

Investigation of mechanical properties in general and long-term creep behavior of the geotextile fabrics in particular, has a considerable importance due to the relevant conventional applications. In this research, in addition to design of a laboratory creep tester apparatus, effect of the various variables on the creep behavior of the woven and needle-punched nonwoven geotextile polyester fabrics was studied. The obtained results for the woven geotextile fabrics showed that more weft density causes to increase creep value; although, higher magnitude of the weft density can reduce rate of creep enhancement due to less movement ability between weft and warp yarns. The secondary creep characteristic for the different studied weft yarn structures is also evaluated at the same level. The results of the nonwoven geotextile fabrics demonstrated that increasing all parameters of needle penetration depth, areal weight and punch density leads to a reduction in the amount of creep. It should be noted that the amount of creep strain in the nonwoven geotextile fabrics were much higher than that of woven geotextile fabrics. It was also concluded that the magnitude of the creep strain for the both studied geotextile fabrics initially reaches to the maximum value and then meets a nearly regular behavior. This phenomenon happens for the nonwoven geotextile fabrics in the less time than what it is necessary for the woven geotextile fabrics. In the other word, the studied nonwoven geotextile fabrics show more stable creep behavior in the long-term condition.
