What is knit process?
Knitting is a process of using long needles to interlink or knot a series of loops made by one continuous thread. Each loop or knot connects to another one, and when enough loops have been made, the result is a flat piece of material called a textile.
How the fabric quality can be measured for a knitted fabric?
To inspect your fabric rolls according to the 4-point system, you must measure the fabric length first. Generally, the knitted fabrics come with the following specifications: Weight of the fabric roll in kilograms. Fabric weight in grams per square meter (GSM)
What are the key qualities of knit fabric?
6 Characteristics of Knit Fabric
- Stretchy and flexible. Since knit fabric forms from a series of loops, it’s incredibly stretchy and can stretch both in width and length.
- Wrinkle-resistant.
- Soft.
- Easy to maintain.
- Easy to damage.
- Difficult to sew.
What are the quality specifications of woven and knitted fabrics?
Quality Parameters of Woven, Knitted and Nonwoven Fabrics
- Dimensional characteristics: Length.
- Weight of fabric: Weight per unit area.
- Fabric strength and extensibility: Tensile strength.
- Threads per inch of fabric: Ends per inch.
- Yarn count: Warp count.
- Crimp: Warp crimp.
- Handle:
- Crease resistance and crease recovery.
What is the purpose of knitting?
Knitting is a method by which yarn is manipulated to create a textile, or fabric. It is used to create many types of garments. Knitting may be done by hand or by machine.
What is the importance of knitting?
In addition to being fun and creative, knitting has health benefits. It reduces stress, jumpstarts literacy, and reforms inmates. Studies show that knitting can even keep Alzheimer’s at bay!
What is fabric inspection procedure?
DEFINITION: Fabric Inspection is systematic observation of fabrics to decide whether it meets: Client’s specification in terms of count/construction, color, design, measurement specifications, hand/feel and other specific quality parameters laid down by the clients.
What are the knitting types?
The two basic types of knits are the weft, or filling knits—including plain, rib, purl, pattern, and double knits—and the warp knits—including tricot, raschel, and milanese.
What are benefits of knitting?
Knitting has been proven to have therapeutic elements that can effectively reduce stress and help beat the negative elements of stress. If you are knitting, it is highly likely that you will end up with some piece of clothing or article that can serve a utilitarian purpose.
How can you tell the quality of yarn?
Yarn is tested on a machine that spins one meter length and then weighs is to get a strength measurement. The larger the size, the heavier the yarn. Breaking strength is classified into two methods: single end strength testing.
What is yarn testing?
Yarn test methods that are used when values such as tenacity, elongation or shrinkage are determined. Test room conditions. Linear density. Breaking force and elongation at break. Tenacity.
What are the 2 types of knitting?
What is knitting and types of knitting?
Knit fabrics can generally be stretched to a greater degree than woven types. The two basic types of knits are the weft, or filling knits—including plain, rib, purl, pattern, and double knits—and the warp knits—including tricot, raschel, and milanese.
What are the two methods of knitting?
In knitting, there are two basic styles of technique: the English method and the German or Continental method. The only real difference lies in how the yarn is held. With the English method, the working yarn is held in the right hand; with the Continental method, it is held in the left.
What is 4 point quality system?
The 4-Point System assigns 1, 2, 3 and 4 penalty points according to the size, quality, and significance of the defect. No more than 4 penalty points is assigned for any single flaw. A defect can be measured either length or width direction; the system remains the same. Only major errors are considered.
What is AQL in garment industry?
Accepted Quality Level (AQL): AQL means Acceptable Quality Level. In any business process, before accepting the finished goods from the manufacturer buyer do inspection of goods. It is so much important in export garment sector.
How to control the quality control during the knitting process?
• Quality control during the knitting process • In order to produce faultless knitted fabric, precision in the settings of the knitting machine is essential during the whole knitting process. The optimal setting of a knitting machine should be balanced in the following parameters: 19 20. • Yarn tension before and after the yarn feeder.
How do knitting manufacturers maintain their place in the textile market?
Therefore, knitting manufacturers have to maintain their place in the competitive textile and clothing market by improving quality and maximizing productivity. The high production speed in circular machine knitting may generate fabric faults or defects that are regarded as a trade-off against fabric quality.
How to measure the quality of knitted fabric?
Each knitted fabric has its own unique elastic property, which is measured by bursting strength testing methods. • knitted fabric quality is usually defined as a number of loops in a square of prescribed dimensions (known as loop density) and represented by the number of loops per square inch or loops per square centimetre. 10 11.
Why is it important to monitor the knitting process?
• As a matter of fact, an effective monitoring of the knitting process is required. Its function is to avoid or detect the fabric faults as well as to locate the defect and its causes as soon as possible in attempts to cut down the undesirable return of goods and avoiding productivity and quality losses. 7 8. • Weight per unit area.
