The fabric of small circular knitting machine

The fabric of small circular knitting machine is belong to weft knitted fabric. It can be used for the yarn uniformity assessment and the dyeing affinity quality control of yarn.

How to produce this fabric?

We often use two types of machines to produce fabrics. Generally, weaving machine produces the woven fabric, knitting machine manufactures the knitted fabric.

This fabric was made by small circular knitting machine, as shown above.

Weaving

Weaving is the process of forming woven fabrics with yarn as warp and weft according to different fabric structures. It usually consists of three parts:

  • At first, making warp yarn into weaving shaft
  • Then, making weft yarn into twisting (or bobbin)
  • At last, weaving and finishing

Weaving is an important part of the textile industry production. Based on the type of raw materials. We can divide weaving into cotton weaving, wool weaving, silk weaving and hemp weaving. All in all, all of the products are woven fabric.

knitting

Knitting is the process of using knitting needles to form coils of various materials and yarns. After that, the needles connect them into knitted fabrics. Knitwear products are also suit for  industry and agriculture, medical care and national defense, etc. In this process, the yarn can be wound horizontally or longitudinally. Cross knitted fabric is weft knitting and longitudinal knitting is warp knitting. The picture below shows the winding patterns of warp and weft knitting.

The differences between woven fabric and knitted fabric

 Woven fabricKnitted fabric
Organization structureThe fabric consisting of two or more groups of perpendicular yarns interwoven at 90 degree angles.The yarn is sequentially bent into coils, and the coils are wrapped in each other to form the fabric.
Basic unit of fabric organizationEach intersection point between warp and weft is  tissue point. This tissue point is the smallest basic unit of woven fabric.The coil is the smallest basic unit of a knitted fabric. And the coil consists of a spatial curve of coiled and extended threads
Characteristics of fabric structureThere is little relation between warp and weft extension and contraction. So the fabric is generally compact and stiff.Knitted fabric can stretch in all directions, it’s very elastic. Because knitted fabric is formed by the hole coil. It has great permeability and soft feel.

Combing Process in Spinning

Image
Before processing cotton, wool, and silk fibers into fabrics, the process of removing impurities and short fibers in the fibers with a combing machine is called combing. The texture, washability and durability of the fabric produced through this process are greatly improved compared with carded fabrics. The following introduces the composition of the combing machine and the combing process. The kinematic coordination relationship of the main parts on the combing machine is indicated by a dial. The disc is mounted on the combing machine and rotates synchronously with the cylinder, which is generally called the indexing disc. The index plate is divided into 40 equal parts along the circumference, and each equal part is 9°, which becomes one index. The working cycle refers to the time interval between the combing cylinder of the intermittent combing machine corresponding to the two actions of combing the whiskers. That is: the first row of needles in the combing cylinder goes to the botto

Twist Test Methods and Influencing Factors

Image
  Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To understand twist testing, you must first understand what twisting is. Twisting is a necessary condition for yarn formation. Short fibers can be made into yarns with certain physical and mechanical properties through twisting; filaments often need to be twisted in order to increase the tightness between single filaments, facilitate processing, and improve fabric properties. Number of twists Twisting is to cause two cross-sections of parallel straight fiber slivers to rotate relative to each other. The number of relative rotations of the two cross-sections is called the number of twists. Twist Twist refers to the number of twists per unit length of yarn . Twist coefficient In actual production, the twist coefficient is of

Garment Dyeing-Special Dyeing Method In Textile

Image
Garment dyeing is a relatively special dyeing process for textiles and garments. Many people may not know much about this dyeing process. In the impression of most people, textile and clothing products are dyed in the fabric period, and garment dyeing is a dyeing process that breaks people’s cognitive limitations on textile dyeing. ​What is garment dyeing ​Garment dyeing means that dyeing the one not in the fabric type but in the garment type itself. The garment type mentioned above include socks, towels, sportswear, shirts, plush toys (without fillers), T-shirts, pants, bathrobes, handkerchiefs, bath mats, carpets, scarves, etc. The material of these garments can be wool, linen, silk and cotton of natural fibers. But most garments are made of cotton or a cotton-rich blends. Garment dyeing imparts vibrant colors to garments. The clothes such as denim garments, tops, sportswear and casual clothing with garment dyeing can provide a distinctive special effect. Garment dyeing method Garmen
