The results indicate that effect of fiber and knitted fabric structure on mechanical and functional properties are significant. It can be concluded that rib fabrics have overall better properties as compared to single jersey knitted fabrics. mechanical properties. Onal and Candan [10] investigated effects of fabric tightness, yarn type, fiber blend and laundering cycle on shrinkage of weft knitted fabrics. They found that double pique knits shrink less widthwise but more lengthwise than the other knit types. Yarn type and fiber.

Mechanical properties are important for all textile users including fabric processors, garment manufacturers, designers and customers. The tensile strength of fabrics is one of the most important physical properties of the fabrics. The tensile strength of the fabric contributes greatly to .   12 Handmade knit fabric. Knitting is a hobby to countless men and women all across the world. With the help of knitting needles and yarn and countless hours of patient hand labour beautiful fabric is knitted and made into clothes – more beautiful than any machine can conjure up – because of the love and effort that goes into each piece.

  This paper reports on an investigation of physical properties on some of the clothing comfort properties of knitted fabrics. Fabric parameters such as fabric density, fabric thickness and fabric weight have been considered to be correlated to air and water vapor permeability, and also moisture management properties which includes accumulative one-way transport index and overall .

Effect of fabric mechanical properties on the sewing performance of knitted fabrics by Mhairi E. Leach Download PDF EPUB FB2

The fabric mechanical properties, in turn, are dependent upon the fabric type (e.g. knitted or woven) and structure (e.g. tightness, yarn cross-over point density, yarn unit segment and float length), yarn structure (e.g. linear density, twist, hairiness and internal structure) and fibre mechanical and other properties (e.g.

elastic and visco. Effect of mechanical and physical properties on fabric hand thoroughly explores the techniques and issues involved in this difficult subject.

It begins by looking at the concepts of fabric hand, with chapters on the developments in hand measurement, the application of statistical methods and the differences in fabric hand between different.

The effect of knit structure on areal density, fabric thickness, air permeability, drape ability, stretch and recovery, shrinkage, and low-stress mechanical properties are investigated, and it was. So, knitted fabrics are treated with fabric softeners applied in the final finishing stages in order to improve fabric performance during sewing process, to improve fabric handle and the.

The mechanical performance of the composites which are reinforced with glass knitted fabrics composed of tuck stitches have been investigated. Tensile, compression, impact and compression-after-impact (CAI) tests were performed and the results of the composites reinforced with full cardigan derivative knitted fabrics and 1 × 1 rib knitted.

Silicone softeners make fabric soft, brilliant, greasy and more elastic, resulting is acceptable handle. In this research work, the effect of using different silicone softeners on pilling resistance and on some physical and mechanical properties of knitted fabrics was evaluated.

Industrially applied silicone softeners of three different types (macro, semi-micro, micro) were used on fabrics. Danmei Sun, in High-Performance Apparel, Abstract. Fabric handle, together with the surface and mechanical properties, is a very important characteristic affecting the quality of fabrics and this chapter, an introduction to fabric handle, the influential factors of handle evaluation including the manufacturing processes of fabrics and apparel, and the surface and low-stress.

the non-linearity in the surface and mechanical properties of the fabrics which relate to fabric handle. The measurement of the mechanical pro perties of textile fabrics, especiall y in their. of knitted fabrics [16]. Fabric shrinkage is a serious problem originating from dimensional changes in the fabric.

Yarn is exposed to various tensions during knitting process and the relaxation process changes the dimension of the knitted fabric [17]. The effect of knit structures on fabric shrinkage has not been investigated enough [11].

The low stress mechanical properties of fabrics (e.g., bending, shear, extension) are objectively measured to assess the tactile characteristics of fabrics. Kawabata Evaluation Systems for Fabrics (KES-F) and FAST (Fabrics Analysis by Simple Tests) systems are available for measuring the fabric handle related characteristics.

Several processes in textile finishing involve a modification on fabric sensorial and mechanical properties.

This paper tries to evaluate the effect of four different washes on the denim fabric tactile properties using a sensory analysis.

The studied washes were rinse, stone1, stone2 and stone bleach. The feed dogs on your machine feed the fabric through evenly.

When sewing a knit fabric, it's important to let the fabric feed itself under the presser foot without pulling the fabric. If a knit is stretched while sewing, it will generally stay stretched after it is sewn as well. This creates an undesirable and unprofessional finish.

Sew a test. We need to make sure that the customer is aware of the properties and characteristics of the fabrics. It is the designer's responsibility to select the appropriate fabrics for their intended applications, but it is the responsibility of the fabric producer to provide as much information as possible to help customers make appropriate fabric selections.

The influence of different processing stages on the low stress mechanical and surface properties of cotton knitted fabrics has been studied. The KES-FB system has been used for the measurements of. Fabric-reinforced cementitious matrices (FRCM) are promising technologies that respond to today’s architectural approaches.

However, due to their high strength and ductility, they are starting to be implemented in buildings as strengthening systems. In this experimental study, the amount of fiber along the load direction in high-strength cementitious matrices and the effects of the fiber.

Synthetic and smart fibres used in sportswear 6. Discussions 7. Seam performance of a garment also depends on structural and mechanical properties of the fabric and strength, extensibility, security, durability, appearance and efficiency of the seams.

Seam strength and seam efficiency should be tested to determine the effect of sewing parameters on sewing performance. The medium ball point has a specially designed eye and scarf to prevent skipped stitches.

I use these on thicker fabrics like swimsuit fabric, elastic, and ponte de roma. This needle is great for the fabrics that seem to cause a lot of skipped stitches.

Don’t miss tips for sewing swimsuit fabric. The influence of preform stretching on mechanical properties of weft knitted PP/glass fibre composites was estimated. Stretching of Rib weft knitted fabric was performed prior to consolidation in a wale or course direction and biaxially.

Preform stretching increased tensile and bending strength of composite as a result of additional orientation of the reinforcing fibres in the stretching.

The effects of deforming knitted fabrics on the tensile and compressive properties of their composites have been investigated for the weft-knit Milano rib fibre architecture.

The properties have been studied for both the course and wale directions for composites with fabrics. TABLE II.

Properties of knitted fabrics. Zhang [13] used 12 mm as the predetermined bagging height for woven fabrics. Because knitted fabric is subjected to much higher deformations during use, a predetermined bagging height of 21 mm was used.
