Specification Requirements4.1 The properties of knitted upholstery fabrics shall con-form to the specification requirements in Table 1.5. Significance and Use5.1 Fabrics intended for this end-use should meet all of the
18、requirements listed in Table 1.5.2 It should be recognized that fabrics can be producedutilizing an almost infinite number of combinations of con-struction variables (for example, type of fibers, percentage offibers, yarn twist, yarn number, warp and pick count, chemicaland mechanical finishes.) Add

20、nd-use.5.3 The uses and significance of particular properties andtest method are discussed in the approprjiate sections of thespecified test methods.6. Test Methods6.1 Resistance to Yarn SlippageDetermine the resistanceto yarn slippage (seam integrity) as directed in Test MethodD 4033.NOTE 2Yarn sli
21、ppage at the seams in knit fabrics is a relatively rareoccurrence, limited to certain types of knit fabrics, for example, coarse-gage Raschels and weft insertion knits. By a substantial majority, thefailures which occur at the seams in knit fabrics are splitting or tearingcaused by needle cutting or
22、 weak yarns, or both, and stitch line threadbreakage. All or any of these problems can be discovered in Test MethodD 4033 if they exist in any fabric or stitch line. If it is suspected that theproblem is needle cutting, seams should be sewn with progressivelysmaller needles until a “passing” result
23、is obtained. Then it is equallyimportant to specify that production on that particular fabric should besewn only with the needle size and type with which the “passing” resultwas obtained. The sewn seam shall contain a stitch density of sevenstitches per inch (25.4 mm) and a minimum of 0.5-in. (12.7-
24、mm) seamallowance. Experience has indicated that a Size 22 (or smaller) needlewith a light ball point will successfully sew most knitted upholsteryfabrics; however, if needle cutting problems do occur, simply changing tosmaller ball point needles will usually solve most problems.
