The presence of defects in cold mercerizing of cotton goods led to the creation of a new method, called hot mercerizing in which caustic soda solution is used at a high temperature. Hot mercerizing is successfully used in cotton blended with some other fibers. In cotton/polyester blend fabrics, this treatment serves a dual purpose: subjectively, it imparts a silklike soft handle to the po...

We present a new procedural method for photorealistic rendering of woven fabric material. The goal of our research is to provide a new procedural method that renders photorealistic woven fabric without any measured data. The proposed method models the reflectance properties of woven fabric with alternating anisotropy and yarn-level surface normal manipulation. The experimental results show the ...

Softness is one of the most important properties for an apparel fabric. This paper investigated the feasibility of objective evaluation of fabric softness by measuring the forces of pulling a fabric specimen through a series of parallel pins. The specific pulling forces of fabric specimens were compared with those indexes obtained both from FAST (Fabric Assurance By Simple Testing) tests and su...

Fabric-based protective clothing is widely used for occupational safety of firefighters/industrial workers. The aim of this paper is to study thermal protective performance provided by fabric systems and to propose an effective model for predicting the thermal protective performance under various thermal exposures. Different fabric systems that are commonly used to manufacture thermal protectiv...

This paper is focused on the segmentation of the fabric weave patterns for the urgent requirement of fabric imitative design and redesign.The weave patterns related to the fabric yarn are determined by a new technology, which is called bidimensional mode decomposition based method. The proposed method first iteratively decompose the underlying fabric image into a number of intrinsic mode functi...

In order to correctly identify the fabric density, a new algorithm based on binary feature matrix is proposed in this paper. A best threshold plane is determined by the gray level of fabric image, the 3D gray image of fabric is segmented according to the best threshold plane and a gray image of feature cluster is obtained. Then the feature cluster is normalized to transform the fabric image int...

While tailoring a garment or a technical textile, relaxation processes of a knitted fabric after production have to be taken into account. Such dimensional changes can occur during a long time of dry relaxation, during wet relaxation, or during washing relaxation, the latter having the strongest infl uence on a fabric. Besides fabric construction and yarn material, the dimensions of a knitted f...

We describe a fast (linear time) procedure to optimally size transistors in a chain of multi-input gates/stages. The fast sizing is used in a simultaneous sizing and restructuring optimization procedure, to accurately predict relative optimal performance of alternative circuit structures for a given total area. The idea extends the concept of optimally sizing a buffer chain[5], and uses taperin...

In the present paper, a study of the effects of fabric weight, fiber cross-sectional shapes (round, hollow and trilobal) and presence of reinforcing material on the compression properties (initial thickness, percentage compression, percentage thickness loss and percentage compression resilience) of polyester needle punched industrial nonwoven fabrics is presented. It was found that for fabrics ...

A granular material is most likely to possess an initial anisotropic structure due to the depositional process or the previous stress history. There is also induced fabric anisotropy during shearing. Concerning the significant influence of fabric anisotropy on the stress-strain behaviour of a granular material, in-depth investigation on the two kinds of fabric anisotropy is essential. Initial f...
