Compression behaviour of hand-tufted carpets: Part II—Effect of cyclic compressive load

305-311The effect of cyclic compressive load on compression characteristics of wool and acrylic hand-tufted carpets has been studied. Wool carpets exhibit higher compression and recovery than the acrylic carpets with similar construction. Compression and matting decrease with an increase in pile density. Percentage recovery of the carpets is found to increase with increase in the number of compression cycle

Compression behaviour of hand-tufted carpets: Part I–Effect of short-term static and dynamic loading

139-144The effect of static and dynamic loading on the compression characteristics of hand tufted carpets has been studied using two types of pile materials. Wool tufted carpets are found to show better retention of thickness. Higher tuft density is found to assist retention of thickness, while higher pile height results in more thickness loss. Thickness loss is also found to be more at the initial impacts, while the recovery rate is found to be more at the initial stage

Pokazatelji mono-fraktalnosti emisije protona u sudarima 24Mg – AgBr na 4.5 A GeV

This paper presents a fractal analysis of emission of medium-energy target protons from 24Mg – AgBr interactions at 4.5 A GeV, in terms of their emission angle (θ) and azimuthal angle (φ), following the method proposed by F. Takagi. The generalised dimensions Dq have been calculated for q = 2, 3 and 4. The values are almost independent of the order for both phase spaces, suggesting mono-fractality of proton emission in heavy ion interactions.Predstavljamo fraktalnu analizu emisije protona srednjih energija iz mete u sudarima 24Mg – AgBr na 4.5 A GeV, prema kutu njihove emisije (θ) i azimutalnom kutu (φ), slijedeći metodu F. Takagija. Izračunali smo poopćene dimenzije Dq za q = 2, 3 i 4. Te su vrijednosti gotovo neovisne o redu za oba fazna prostora, što ukazuje na mogućnost mono-fraktalne emisije protona u sudarima teških iona

Razbijanje jezgri u sudarima 28Si-AgBr na 14.5 AGeV – podaci o dvo- i višečestičnim dinamičkim korelacijama

This paper reports an investigation of the two-particle and three-particle short-range angular correlations among the target fragments produced in 28Si-AgBr interactions at 14.5 AGeV. The experimental data have been compared with Monte Carlo simulated events to extract dynamical correlations. The data exhibit strong two-particle and three-particle correlations among the target fragments. The data further indicate the occurrence of the so-called side splash phenomena and disfavour the evaporation model.Izvješćujemo o istraživanju dvo- i tročestičnih kratko-dosežnih korelacija dijelova mete proizvedenih u sudarima 28Si–AgBr na 14.5 AGeV. Eksperimetalni se podaci uspoređuju s oponašanima izračunatim Monte Carlo metodom radi razdvajanja dinamičkih korelacija. Podaci ukazuju na pojavu tzv. pljuštenja (engl. “splash”) i nisu u skladu s modelom isparavanja

Effect of friction drum speed and yarn delivery rate combination for a constant friction ratio on quality of friction-spun yarns

33-37For a constant friction ratio, the combination of friction drum speed and yarn delivery rate significantly affect the quality of friction-spun yarns. The increase in combination values, in general, deteriorates the quality of DREF-II yarns in respect of tenacity, breaking extension, abrasion resistance and unevenness. However, in case of DREF-III yarns, these characteristics show an improvement when drum speed and delivery rate are proportionately increased to maintain the given constant friction ratio
