Characterization of Flammability and Low Stress Mechanical Properties (Compression and Shear) of Basofil ® Fibers and its Blends (original) (raw)

Chemical Science Review and Letters Characterization of Flammability and Low Stress Mechanical Properties (Compression and Shear) of Basofil ® Fibers and its Blends

Basofil ® fiber exhibits excellent fire protection and thermal stability along with resistance to chemical, hydrolysis and ultraviolet radiation. Open-end spun yarns were produced from Basofil® fiber and its blends, the necessary tensile properties were tested. 100% Basofil ® yarns show less tenacity and breaking elongation due to fiber density, brittleness, and lower cohesion between fibers. Flammability characteristics of Basofil ® fiber have enhanced in its blends. The compression and shear properties of the above mentioned fabric samples exhibit very high thermal dimensional stability. This study helps the yarn and fabric manufacturer to engineer the structures suitable for the development of Defence apparels, civilian apparels and Home furnishings.

Effects of Aramid Sewing Yarn Type and Fabric Compositions on Some Seam Properties of High Performance Fire Retardant Fabrics

TEXTEH Proceedings, 2021

High performance fire retardant textiles are utilized in different end-use areas such as workwear, firefighter garments, military textiles etc. These textiles are produced to protect the wearer against harsh environmental/occupational hazards and to bear forces during occupation. In the literature, fire-retardancy and mechanical performance of high performance fire retardant textiles are searched in details. Nevertheless, in most of these studies, samples were in the form of fibres or fabrics. When the fabrics are cut and sewn together to form a textile article, their mechanical properties change along the seam lines. In spite of this fact, seam properties of high performance fire retardant fabrics were not studied in the literature, systematically. Therefore, in this study, some seam properties of high performance fire retardant fabrics were studied as a preliminary work in this subject. According to results, seam strength of all samples were considerably lower when compared to str...

Development of Fabrics using Various Fibres Blends to Develop Protective Clothing for Oil Gas Industry Workers

International Journal of Engineering Research and, 2016

Oil and Gas industries contain high concentrations of highly flammable substances. These are placed in high risk categories as there is a continuous threat to the life of workers due to presence of highly inflammable gases in the surrounding atmosphere. In India there are approx 41,947 (2011) retail outlets, 22 refineries and 178/637 rig wells where huge number of manpower is engaged. Fire accidents are very common at fuel stations which results devastating burns and some time death of workers. A little negligence may cause havoc. Most of the cases these injuries due to burn are preventable if the right type of work wear is worn by the attendants. As per Government of India, the majority of severe and fatal burn injuries are due to the individual's clothing igniting and continuing to burn, not by the exposure itself. Keeping the safety of workers in oil and gas industry in mind, a survey was conducted in Delhi and NCR to understand the effectiveness of worker's uniform to tackle fire hazard. The work-wear and fabric sample used by attendants were also collected evaluated for their suitability. The results indicated that these collected samples were not qualified the passing criteria of flammability. The current study aimed to develop different woven blended fabrics. FR viscose (V1), Nylon 6, 6 (N1) and Modacrylic (M1) 100 percent compositions and their blended fabrics such as FR viscose 50 % / Nylon 6, 6 20 %/ Modacrylic 30% (VNM523) and VNM325 were produced. Produced fabrics were evaluated for limiting oxygen index, radiant heat index, contact heat index, convective heat index, heat resistance, limited flame spread and mechanical properties after 5 and 50 washes according to ISO 11612 International standard method for protective clothing for industrial workers. From the study it was clear that fabric samples M1, VNM523, VNM325 along with commercially available MPA samples are meeting the all requirements of ISO 11612. This study will guide the manufacturers to select suitable fibre blends to make the product cost effective without compromise the minimum requirement as mentioned in the ISO 11612.

In this study, the properties of flame retardant woven fabrics produced from the SeaCell®active and SeaCell®pure yarns, which are known as ecological and medical textile materials, were investigated. The yarns were produced from SeaCell® stapel fibres and then were woven into fabric. After dyeing, the fabrics flame retardants which has phosphorus–inorganic synergism and organophosphorus compounds (N-hydroxymethyl-3-dimethylphosphonopropionamide), were applied to the the SeaCell®active and SeaCell®pure fabrics, and later the flame retardant properties were determined before and after washing processes. In addition to that, thermal properties of the fabrics and the effects of flame retardants were studied. The flammability of the flame retardant treated SeaCell®active and SeaCell®pure were characterized by using limiting oxygen index (LOI). Structural changes of the treated SeaCell®active and SeaCell®pure and the compounds were carried out by using thermal analysis methods of differen...

2019

Two sets of yarns have been produced on ring spinningsystem. In the first set, flame-retardant viscose and meta-aramidare blended in three different ratios of 30:70, 50:50 and 70:30, andin the second set, flame-retardant viscose, nylon 66 and metaaramidare blended in two different ratios of 30:20:50 and50:20:30 respectively. These yarns are converted in to wovenfabrics and evaluated for limiting oxygen, contact heat, radianheat and convective heat indices. One way analysis of variance(ANOVA) has been applied to find out the effect of different fibreblends on various flame and thermal properties. It is observed thatthere is relationship between fibre contents in the blend and flameand thermal resistant properties.

A critical study of the effects of flame retardancy on different knit fabrics

Journal of Textile Engineering & Fashion Technology, 2021

A novel flame retardant especially Pekoflam HFC was synthesized to improve the flame retardancy of fabric. Pekoflam HFC is especially suitable for flame retardant back coatings of synthetic fibre based home textiles and high-performance technical textiles. The flame retardancy of the samples was characterized by the spray method and the vertical burning test. The results indicated that the flame retardant had excellent flame retardancy and durability for cellulosic fabrics. The cotton knit fabric treated with Pekoflam HFC obtained the optimum flame retardancy with the decreased char length. Combustion behaviors of treated cotton fabric were tested by manual observation. After treatment, it found that the ignition time increased, and the values of total heat release, heat release rate and mass loss decreased. The strength and durability of treated fabric were studied by tear force test and washing durability test, respectively.

Effect of radiant heat exposure on structure and mechanical properties of thermal protective fabrics

Polymer, 2021

The heat protective performance of thermal protective fabrics is related to the multiscale structure of the fibrous material and the composite design of a multilayered fabric system. In this study, a molecular interpretation is provided to explain the structural changes within fibers to correlate with the mechanical properties of the outermost layer fabric made up of m-aramid blended with (5-10) % p-aramid upon various radiant heat exposures. An increase in crystallinity due to limited polymer chain movement but no change in lamellar spacing was observed when fabrics were exposed below the glass transition temperature which resulted in no change in mechanical properties. A noticeable increase in lamellar spacing and crystallinity was obtained when the temperature during the heat exposures is in the proximity of 375 • C of the fabric layer due to the fibrillar-to-lamellar transformation. Even though no visible changes were observed by scanning electron microscopy (SEM) in the fabric exposed to the aforementioned thermal conditions, we found that their mechanical properties are compromised due to the structural changes within fibers of the fabrics. Therefore, further use of fabrics could be potentially dangerous for the user. Furthermore, for expoheat exposures where the temperature of the fabrics reaches above the degradation point, thermal decomposition occurs which is noticed by its hard and brittle behavior. The inner layers of both the fabric systems mostly remain intact until the thermal degradation of the outermost layers. This study provides an in-depth understanding of molecular mechanisms of structural changes that are in line with changes in the mechanical properties. The understanding of the structure-mechanical property relationship could serve as basic knowledge for the design and fabrication of high-performance fabrics for various fire environments.
