Ends and Picks

The unit will be of flood type that will cool the products as they are conveyed into the channel filled with water. The products will be dropped into the channel filled with water at one end and picked up at the other end. The channel can be as wide as 3 m and as high as 90 cm. The water is to be circulated and cooled by the evaporator section of a lefiigeratioii syslem. The refrigerant temperature inside the coils is to be -2°C, and the water temperature is not to drop below l°C and not to e.xceed 6°C. 

This is a modification of plain weave in which two or more ends and picks weave as one, moving one yarn for each end or pick (Figure 21.8). It is more dense than plain weave and more flexible, tends to abrade more readily and is not as strong as a plain weave. If two warp yarns pass over and under two weft yarns, this gives a 2 x 2 basket construction. The first... 

Chiffon n. A plain weave, lightweight, sheer, transparent fabric made from fine, highly twisted yarns. It is usually a square fabric, i.e., having approximately the same number of ends and picks and the same count in both warp and filling. 

Thread count n. (1) The number of ends and picks per inch in a woven cloth. (2) The number of wales and courses per inch in a knit fabric. 

Usually fabric dimensional parameters are determined as primary requirements for fabric selection these include thread linear density, ends and picks per cm in woven... 

A cruciform structure is shown in Figure 9.18. The 100% fill fiber of each flap goes through the intersection. Each flap consists of four layers, and again they are connected by layer-to-layer interlock weave based on a plain weave. The typical construction of each layer is 16 x 16 ends and picks per inch in the case of 6K carbon fibers and 16x8 ends and picks per inch in the case of 6K carbon warp fibers and 12K carbon fill fibers. A double cruciform with all sides tapered was also woven using a modified narrow fabric shuttle loom. 

From what has been discussed above it can be reasoned that the fabric mass per unit area will be governed by the number of ends and picks per unit area the value of weft and warp crimp and by the mass per unit length of... 

The number of warp or weft yams per unit space, known as ends per inch or picks per inch, respectively, decides the fabric s strength in a particular direction and the openness of the fabric s stracture. Also, the weight of the fabric, ie, the fabric s mass per unit area, will be governed by the number of ends and picks per unit area and the count of the warp and weft yams. The yam count defines the coarseness or fineness of the yam. The international system unit for yam count is the tex, which is the weight in grams of a 1000-m length of yam.
