(bzs. rnk.), tablo ; 29 cm.Günümüzde, denim kumaştan üretilen giysiler yaş, cinsiyet ve sosyal statü sınırlaması olmadan, çok geniş bir alıcı kitlesi tarafından yaygın olarak kullanılmaktadır. İlk zamanlarda, %100 pamuk iplikleri kullanılarak üretilen denim kumaşlar, modanın da etkisiyle günümüzde farklı lifler içeren ipliklerden dokunmuş, farklı renk, görünüm ve performans özelliklerine sahip kumaşlar olarak karşımıza çıkmaktadırlar. Tekstilde yenilik ve farklılık arayışları sonucu ortaya çıkmış olan krep yapılı iplikler ilk önceleri selüloz asetat liflerinden üretilmekteydi. Son yıllarda polyester, filament yapılı krep iplik üretiminde yaygın olarak tercih edilmektedir. Filament esaslı krep iplikler çoğunlukla kompozit yapıda (çok bileşenli) olmalarından dolayı, sonradan görecekleri sıcak işlemde davranışları farklı olmaktadır. Bu işlem kumaş formunda iken yapıldığında kumaşta da krep etkisi kendisini göstermektedir. Bu çalışmada, krep ipliklerin denim kumaştaki etkisini ve performansını gözlemlemek amacıyla aynı numarada fakat farklı filament sayılarında polyester esaslı tekstüre krep iplikler üretilmiştir. Daha sonra bu iplikler denim kumaş üretiminde atkı yönünde kullanılarak numune kumaşlar elde edilmiştir. Çözgü iplikleri standart olan bu numune denim kumaşlara kalite kontrol testleri uygulanarak performans özellikleri araştırılmıştır. Elde edilen kumaş test sonuçlarının istatiksel analizleri SPSS istatistik paket programı kullanılarak gerçekleştirilmiştir.Today, the garments made from denim fabrics widely used by a wide audience of buyers without limitation of age, gender and social status. Early on, denim fabrics were produced fron 100% cotton fabrics but, they are now on the market as woven of the yarns containd different fibers with different colours, appearence and performance properties under the influence of fashion, too. Crepe yarns that were the result of searches for innovation and diversity in textiles were produced from cellulose acetate fibers in the beginning. In recent years, polyester fibre widely preferred for producing filament crepe yarn. Because the filament based crepe yarns are mostly have composite structure (multicomponent), their own behavior in the hot process as next process are different. When this process applied on fabric form, crepe effect is obtained on fabric. In this study, polyester based textured crepe yarns were produced at the same count but with different filament numbers in order to observe the effect and performance of the crepe yarns on the denim fabric. Then, these yarns were used as weft in fabric to produce samples of denim fabric. The performance characteristics of these samples of denim fabrics produced from standardized warp yarns were investigated by applying quality control tests. Statistical analyzes of the fabric test results were performed using the SPSS statistical package program

Mechanické vlastnosti krepového papiera v ťahu boli veľmi odlišné v pozdĺžnom a priečnom smere pri zaťažení vzhľadom na povrch papiera.The paper deals with the evaluation of the mechanical properties of the crepe paper and chickpaper. The thickness of crepe paper was 300 m with the surface mass 150 g*m-2 and chickpaper paper thickness was 100 m with the surface mass 40 g*m-2. Crepe paper and chickpaper are usually used for chicken breeding. Longitudinal and transversal tensile properties were studied. The tensile behavior was monitored on the motorized test stand ANDILOG STENTOR 1000 (Andilog Technologies, Vitrolles, France).There were measured the tensile properties as modulus of elasticity, maximal elongation, maximal tensile force, tensile strengths, tensile index and strain at break of the longitudinal and transversal samples by testing paper strips. Mean values of the maximal elongation b of longitudinal chickpaper samples were three times smaller than maximal elongation of transversal samples. Mean values of maximal tensile force Ft, tensile strength b tensile indexw and maximal strain at break T of longitudinal chickpaper samples were two times smaller than maximal quantities of transversal samples. Mean values of the tensile modulus of elasticity of longitudinal and transversal chickpaper samples were almost equal. Chickpaper mechanical properties in tension were different in the longitudinal and transversal direction of the original paper surface. Mean values of the maximal elongation b and maximal strain at break T of longitudinal crepe paper samples were sixty times smaller than maximal elongation and maximal strain at break of transversal samples. Mean values of maximal tensile force Ft, tensile strength b andtensile indexw of longitudinal crepe paper samples were fourth times smaller than maximal quantities of transversal samples. Mean values of the tensile modulus of elasticity of longitudinal samples of crepe paper were thirty eight times smaller than values of transversal samples
Revealing the Environmental Footprint of Crepe Rubber Production: A Comprehensive Life Cycle Assessment of a Crepe Rubber Factory in Sri Lanka
No full textNatural rubber, a renewable material with unique properties, is crucial for various products on the modern market. Crepe rubber, a versatile form of natural rubber, is widely used in numerous applications, including footwear soles, medical devices, automotive parts, adhesives, sports equipment, industrial components, musical instruments, and recreational products. Sri Lanka holds a prominent position as a leading producer of premium-quality crepe rubber but faces environmental challenges in its production process. Since previous life cycle assessments (LCAs) in the rubber industry are inadequate to capture the overall environmental impact, the present study attempted to address the gaps by conducting a detailed LCA of a Sri Lankan crepe rubber factory, incorporating a novel index termed the trade-off valuation index (TOVI). The research revealed that fertilizer, water, and electricity use contribute most significantly to crepe rubber production’s environmental impact. To mitigate these impacts, four key improvement options were identified and evaluated through scenario analysis: (1) enhancing fertilizer efficiency, (2) repairing leaky joints and valves, (3) implementing a water reuse system, and (4) installing solar panels. The integration of the TOVI allowed for the prioritization of these options, providing actionable insights for industry stakeholders. This study paves the way for targeted interventions to enhance the sustainability of the natural rubber industry by balancing economic viability with environmental stewardship

CREPE: Learnable Prompting With CLIP Improves Visual Relationship Prediction
No full textIn this paper, we explore the potential of Vision-Language Models (VLMs),
specifically CLIP, in predicting visual object relationships, which involves
interpreting visual features from images into language-based relations. Current
state-of-the-art methods use complex graphical models that utilize language
cues and visual features to address this challenge. We hypothesize that the
strong language priors in CLIP embeddings can simplify these graphical models
paving for a simpler approach. We adopt the UVTransE relation prediction
framework, which learns the relation as a translational embedding with subject,
object, and union box embeddings from a scene. We systematically explore the
design of CLIP-based subject, object, and union-box representations within the
UVTransE framework and propose CREPE (CLIP Representation Enhanced Predicate
Estimation). CREPE utilizes text-based representations for all three bounding
boxes and introduces a novel contrastive training strategy to automatically
infer the text prompt for union-box. Our approach achieves state-of-the-art
performance in predicate estimation, mR@5 27.79, and mR@20 31.95 on the Visual
Genome benchmark, achieving a 15.3\% gain in performance over recent
state-of-the-art at mR@20. This work demonstrates CLIP's effectiveness in
object relation prediction and encourages further research on VLMs in this
challenging domain
Fashion in peril: an investigation into how fashion mirrored change in UK society
No full textThis paper investigates and compares how fashion reacted to the deprivations of the Second World War, with similar deprivation, in the economic recession, beginning in 2008. This resulted in many parallel initiatives that have either been revived or have evolved. The initiatives often threaten recognised systems of fashion, design and consumption. It is driven underground only to re-emerge in different interpretations. Indeed a backlash against ostentation has been a driving force in sustainable fashion which emerged before the recession. Consumers embraced an environmental consciousness which radically altered perceptions towards fashion products and the messages they sent out to the world. The paper also details how final year fashion design students were set a live two day brief, that asked them consider the concept of ‘Fashion in Peril’. This exercise introduced students in a practical way to how fashion can mirror change in Society and also how a sense of individual style and fashion can be maintained in a crisis
The Effect of Addition of Antioxidant 1,2-dihydro-2,2,4-trimethyl-quinoline on Characteristics of Crepe Rubber Modified Asphalt in Short Term Aging and Long Term Aging Conditions
No full textThe use of natural rubber to resist bitumen is usually prone to degradation and aging. One method to overcome this problem is the addition of antioxidants. This study aims to determine the effect of the addition of antioxidants 1,2-dihydro-2,2,4-trimethyl-quinoline (TMQ) on natural rubber modified asphalt crepe rubber and its performance in short-term and long-term aging conditions. The modified rubber asphalt mixture’s manufacture begins by melting the crepe rubber at 200 °C before being mixed in asphalt at 165 °C. Addition of antioxidant TMQ during the stirring process of the mixture of asphalt and melted rubber. The crepe rubber content was 8, 10, and 12% w/w, while the TMQ content was 1, 2, and 3% w/w of the total sample weight. The modified asphalt samples’ characterization included penetration, softening point, weight loss after a rolling thin film oven test (RTFOT), penetration after RTFOT, and Marshall test. Review of the performance of asphalt under short-term aging conditions using a dynamic shear rheometer (DSR). Evaluation of asphalt performance under long-term aging conditions using Fourier-transform infrared spectroscopy (FTIR). The results showed that the fact that the best-modified asphalt product was the addition of 10% crepe rubber and 2% TMQ. The best-modified asphalt characteristics have penetration 68.70 dmm, softening point 55.45 °C, weight loss only 0.0579%, penetration after RTFOT 59.60, Marshall stability 1403.96 kg with optimum asphalt content of 5.50%, and rutting factor (G*/Sinδ) 6.91 kPa and 16.1 kPa before and after RTFOT. Overall, the modified crepe rubber asphalt can improve the performance of the asphalt in terms of durability. Simultaneously, the antioxidant TMQ works very well in increasing the resistance of bitumen to aging in the conditions of short-term aging and long-term aging
On the Treatment of Rayons with Synthetic Resins by means of an Improved Method.:Especially, on the Treatment of Rayon Crepe Fabrics
No full textThe study of an entirely new method of applying synthetic resins to rayons in 3 forms (i.e. in staples, yarns and fabrics) had been started by the author, and abstracts were reported from time to time in the Bell, Inst.Chem. Res. KyotoUniversity during 1949-1952. The author in the present paper deals with the pre-treatment of the material to be processed, especially with that of rayon crepe fabrics, the fiber of the twisted yarns of the fabrics being usually very difficult to be penetrated by the pre-condensate of the resin under the dipping condition now in practice. The pre-treatment accompanied by a good cure was found to be very effective to produce a singular effect of the author's own method, which was characterized by an elastic and soft handle with a high crease recovery, and a shrinkage on wetting that was quite reversible on drying.departmental bulletin pape
