Seven kinds of weft knitted fabrics from glass fiber yarns were used as reinforcement to make fabric/epoxy composite laminates. Tensile tests were carried out to examine and compare the mechanical properties in course and wale direction of these composites. On the basis of experimental results, attempts have been made to analyze some main factors influencing stress-strain curve, ultimate tensile strength and initial elastic modulus of specimens.

Several different kinds of weft knitted fabrics from glass fiber yarns were used as reinforcement to make fabric/polyester composite laminates. Flexural tests were carried out to examine stress- deflection process and compare the mechanical properties in course and wale directions of these composites. The experimental results indicate that the numbers of load-bearing yarn in course and wale direction and the fabric density are the main factors influencing the ultimate tensile strength and initial elastic modulus of specimens.

The lightweight worsted fabric made of Sirofil yarn was developed and its textile performance was studied. By means of conventional testing, KES and FAST, it is concluded that with the coordination of proper fabric design and processing technique, the performance of this innovative fabric is superior to that of the conventional lightweight fabric Furthermore, it is predicted from the relevant parameters that its processability in the following suit manufacture is very desirable.

On the basis of our previous research work, an expressing index was proposed for the lively degree of dynamic fabric drape. Meanwhile, the main factor analysis for parameters of fabric drape was applied and the 5 main factors, comprehensive indexes of expressing aesthetics of fabric drape, were obtained. Through the scored diagrams of main factors of fabric drape aesthetics, 100 kinds of fabric samples could be identified and catalogued. A new method was found out for the objective evaluation of aesthetics of fabric drape.

Based on the processing experiment and sodium flame test this paper deals with the relationship between processing parameters, structure, and filtration property of melt blown fabric. Through the image analysis of Questar micro-images in combination with the SEM observation and the measurement of some macrostructure indices, the relationship between the processing parameters and the structure especially the microstructure is emphasized Finally the effect of somestructure factors on filtration properties is discussed theoretically.

This paper investigates the related strength properties of 3D solid orthogonal panel fabrics under the condition of low strain, then analyses the response of these fabrics to low tensile loads, as well as presents how it is possible to deduce the tensile properties of 3D solid orthogonal panel fabrics from the known properties of their constituent yarns and the fabric structural geometry while fabrics suffer from low strain (less than 10%). The experiments indicate that the relationship between stress and strain for 3D solid orthogonal panel fabrics is parabolic, and the relationship between fabric strain and yarn strain is linear. In addition, yarn strain is much less than fabric strain.

The distribution of the light reflected from various fabric surfaces was studied. A series of samples of different fibers, weaves and colors were investigated. The experiments show that the goniophotometric curves of fabrics change with constituent fibers, weave, dyeing and finishing, and experimental *** goniophotometric curves for fabrics of same kind with different colors are same in general shape, and the reflectance or the height of the curves are changed to the extent of that they are in proportion with the brightness or the tristimulus value Y of the samples. The goniophotometric curve also varies in form when the incident angle is changed. Discussion and explanation for the above mentioned are given. Luster of the samples was calculated with methods suggested by different indexing systems.

The woven fabric can be defined as orthogonal elastomer if the extension force that puts on the fabric is very small. Based on the precondition, the apparent elasticity constants of a woven fabric were analyzed theoretically in the paper. The bias angle (which is between weft yarns and extension direction ) affects apparent elasticity modulus and elasticity coefficient of the fabric in the extension direction. And the experiment describes fluxes of elasticity constants going with the bias angle of the fabric.
