Picks per

Experiment Ten different positions within the conditioner representing typical and extreme locations relative to the air inlet/exhaust openings were selected for analysis. Eight tablets were picked per position their water content was accurately determined on a tablet-to-tablet basis using the Karl Fischer technique. Table 4.7 gives an overview of all results ... 

The number of warp ends and the number of weft picks per unit length in a woven fabric written, e g., 23 x 23, the unit length being 1 inch on the imperial system of measurement. 

The polymer was extruded at 240 C to produce 28-strand multifilament yarn. The yam was hot-stretched and fiber tensile strengths in the range 3-6 g/den (1-2 dpf) could be obtained. The yam was placed on braider bobbins on a 12-carrier machine with 7-ply core. The braid was made with 51 picks per inch and hot-stretched 25% at215 F. 

The weaving of the yarn was conducted on a Draper model X P loom operating at 160 picks per minute. A 115 g/ni (3.4 oz/ydZ) printdoth fabric was produced with approximately 68 ends by 70 picks. The statistical data accumulated during the weaving opera-ation of the three types of yarn treatments are presented In Table VI. The average number of breaks per hour In warp yarn for starch, fermented starch, and enzyme-degraded starch was 1.62, 1.37, and 1.45, respectively. 

Standards from historical records tend to be very dirty (although cheap). For example, in the warehouse, how many cases can be picked per hour From shipping records, determine the number of cases shipped in January, February, and March. From personnel, determine the number of employees in shipping in each month. Divide total cases/total hours to get cases/hr. Ignore changes in product output, product mix, absenteeism, delays, and so on. 

Fiber coimt The number of warp fiber/yarn (ends) and filling fiber/yarn (picks) per inch. Cross section or thickness of fiber, yarn or roving expressed as denier. See Fiber decitex. 

Count In fabric, it is the number (count units) of warp fibers (ends) and filling fibers (picks) per unit of length (cm or in). 

A degree of freedom analysis should be then performed to indicate how many design decision variables need to be picked per volume element. Appendix A gives a detailed overview of a degree of freedom analysis for the case of a complete RD column. 

The fabric count refers to the number of warp yarns (ends) per centimetre and number of filling yarns (picks) per centimetre. For example, a fabric count of 8.5x4.5 means that there are 8.5 ends per centimetre running in the warp (lengthwise) direction and 4.5 picks per centimetre running in the fill (transverse) direction. Fabric count plus the properties of the warp and fill yarns used to weave fabrics are the principal factors which determine fabric strength. 

Count n. (1) A numerical designation of yarn size indicating the relationship of length to weight. (2) The number of warp yarns (ends) and filling yarns (picks) per inch in a woven fabric, or the number of wales and courses per inch in a knit fabric. For example, a fabric count of 68 x 52 indicates 68 ends/in. in the warp and 52 picks/ in. in the filling. 

Finger mark n. A defect of woven fabrics that is seen as an irregular spot showing variation in picks per inch for a limited width. Causes are spreading of warp ends while the loom is in motion and pressure on the fabric between the reed and take-up drum. Kadolph SJJ, Langford AL (2001) Textiles. Pearson Education, New York Vincenti R (ed) (1994) Elsevier s textile dictionary. Elsevier Science and Technology Books, New York. 

Off-square n. (1) A term to describe the difference between the percentage of warp crimp and the percentage of filling crimp. (2) A term referring to a fabric in which the number of ends and the number of picks per inch are not equal. 

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.

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. 

There are multiple stations in a narrow fabric shuttle loom. That means the same structure in multiple stations or different structures can be woven on the same loom depending on the capacity of the Jacquard hooks and the total picks per inch in the structure. It is difficult to produce 3D and complex shapes using carbon and brittle fibers on a needle loom. A narrow fabric needle loom (Hans Walter Kipp, 1989) can also be used to produce some 3D preforms. A typical narrow fabric needle loom is shown in Figure 9.58. The selvedge on the side of filling insertion needle is a true... 

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...
