Hot-melt pressure-sensitive adhesive for seamless bonding of nylon fabric Part II: Process parameter optimization for seamless bonding of nylon fabric

Abstract

This study develops hot melt pressure sensitive adhesives (HMPSAs) for the seamless bonding of nylon fabric, using butyl acrylate as the main monomer material and mixing the functional monomer for polymerization. It is combined with 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide for the photoinitiator and ultraviolet irradiation is used to make a pre-polymer. The effects of butyl acrylate content, type of functional monomer, and 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide content on the molecular weight of acrylate pre-polymer are discussed, following the Taguchi method. The pre-polymer is then mixed with the reactive diluent glycidyl methacrylate blend and with 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide, coated on a release film, irradiated by ultraviolet light, and cured into hot melt pressure sensitive adhesives. The adhesive properties of hot melt pressure sensitive adhesive bonding on nylon include the peel strength, the shear strength, adhesive warpage, adhesive color difference, and adhesive overflow, which are discussed following the Taguchi method and the elimination and choice translating reality method for multi-quality analysis. Hot melt pressure sensitive adhesives are implemented by optimization parameters for practical validation. The results show that the peel strength of hot melt pressure sensitive adhesives is 1.495 kg/cm, the shear strength of hot melt pressure sensitive adhesives is 14.326 kg/cm2, adhesive warpage is 0.93 mm, adhesive color difference is 1.66, and adhesive overflow is 0.97 mm. The performance of HMPSAs in this study is enhanced effective.

Effect of far-infrared fabrics on proliferation and invasion of breast cancer cells

“…The preparation of far-infrared fabrics can generally be achieved by adding far-infrared nanoparticles with high emissivity in the spinning process, or by adding far-infrared absorbent in the finishing process of textiles by coating and dip rolling (Kuo et al. , 2018; Gong et al.…”

“…The preparation of far-infrared fabrics can generally be achieved by adding far-infrared nanoparticles with high emissivity in the spinning process, or by adding far-infrared IJCST 34,6 absorbent in the finishing process of textiles by coating and dip rolling (Kuo et al, 2018;Gong et al, 2018). In this study, six different far-infrared nanoparticles as volcanic (Ma, 2012), bamboo charcoal (Lin et al, 2016), tea carbon (Chen, 2019), coffee carbon (Yang, 2013), graphene and biomass graphene (Yu et al, 2020) were selected to disperse and blend the farinfrared nanoparticles with nylon to obtain yarn (Lin et al, 2012).…”

“…The number of proposals is reduced until the criteria with multiple advantageous proposals are left for multiple attribute decision-making analysis. 19,20 The advantages of ELECTRE include straightforward decision-making logic and systematic processes, as well as clarification of the performance of various proposals. The proposals are classified as Reject and Non-reject and the concordance and discordance indexes of the proposals are established.…”

Multicriteria Optimization of the Mechanical Properties in Laminated Seams

“…The main problem is to create the seams of the appropriate strength properties using the correlated bonding temperature, pressure, and duration time [6]. The optimization of the selected parameters is difficult in respect of the structure and surface properties of fabric, additional finishing, and characteristics of the tape [6,7].…”
