FZ/T 94044-2010Automatic winder (English PDF)

Foreword

Instead of the standard FZ/T 94044-1996 "automatic winder." the main technical differences between this standard and FZ/T 94044-1996 compared as follows.

--- This standard defines the scope of the original standard "automatic winder yarn library" to "automatic winder", extends the standard coverage (See Chapter 1);

--- Increased product type, in addition to yarn type library, the original standard of the standard product type increases the "fine-linked network, centralized automated library yarn feeding tube Type cylinder rewinding automatic winder "(see 3.1);

--- The standard machine type original standard "single winding head (single spindle) single-sided arrangement" to "single winding head (single spindle) Formula" (see 3.2.1);

--- Expanding the scope of the number of winding heads, the present standard of the original standard winding head number "10 ~ 60" to "4 ~ 72" (see 3.2.2);

--- Original standard fitting manner "air splicer, twisting machinery, mechanical knot" to "the formation of knotless yarn air splicer, mechanical rub Twist and other "(see 3.2.5);

--- Expand the speed range of the automatic winder according to the development of technology, the present standard of the original standard winding speed "500m/min ~ 1500m/min "to" 300m/min ~ 2000m/min "(see 3.2.6);

--- Original standard splicer length "12mm ~ 25mm" to "15mm ~ 35mm", focus on ensuring the strength splicing joints, twist Then the length is more in line with actual usage (see Section 4.1.3);

--- The original standard three splice success rate ">=95%" to improve ">=98%" (see 4.2);

--- Cheese length original standard error of the mean "± 2%" raised to "± 1.8%" (see 4.3.2);

--- Original length standard tube gauze length coefficient of variation CV (%) "<=2%" to improve "<=1.8%" (see 4.3.3);

--- References to security test requirements GB 5226.1-2008 (see 4.10 and 5.8);

--- According to "verifiability principle" standard content, delete the reliability requirements of the original standard of 4.11;

--- Cheese length and average error test tube gauze length variation coefficients, according to the national standard GB/T 4743 requirements, Makes provision for one hundred meters to take the weight of the standard yarn yarn way (see 5.3);

--- Increase in the length of the tube gauze length coefficient of variation CV (%) and winding yarn tension coefficient of variation CV (%) calculation formula "× 100", amended the original standard formula error [see equation (6) and (9)];

--- Noise testing, security testing, inspection and product packaging coating according to existing national standards, industry standards revised accordingly Change (see 5.9,5.11 and 5.7 ~ 7.2);

--- The type test conditions of the original winding speed standard "1000m/min" raised to "1200m/min" [see 5.11c)], body Now in recent years substantial progress domestically automatic winder technology;

--- Increasing the need for type testing fourth case "d) the national quality supervision departments type inspection requirements" (see 6.3.1);

--- Increased its product marking requirements (see 7.1).
