Knitted fabric of ammoniac black silk ribbon has write its special function, your dress is worn easily, close-fitting and comfortable. The body is mobile and light. Wear very comfortable softness feels on the body. Main reason ﹕ cares about the expression of the each physics function of knitted fabric of ammoniac black silk ribbon.

1 ﹑ is outspread the stretch fabric that spends ﹕ simple explanation to be certain length, after sufferring drawing of certain outside force, in the OK and stretchy distance inside proper time. Outspread degree of percentage is larger. Make known one's position fabric extensibility can be better.

2 ﹑ spring back spends ﹕ to explain the index that is stretch fabric bounce simply, after outside force of fabric purify drawing, fabric returns the rate that shrink, determine the index of spring back, be out of shape for remains. The tension that it decides fabric is extended be out of shape ability.

3 ﹑ model measures ﹕ cent to be drawing model quantity to follow quantity of spring back model. Drawing model estimates the pulling force when the opposite length with show fabric suffers outside force drawing to arrive certain. Tensile = overcomes stretch fabric screen resilience + the attrition force that overcomes gauze space to coil is out of shape and arise. After quantity of spring back model shows fabric suffers outside force drawing and drawing outside force dismantles, fabric answers the tension of the opposite length with shrink certain. Screen resilience of stretch fabric of screen resilience = - the attrition power that coil is out of shape and produces. Attrition force is small. Pulling force is small. Screen resilience is bigger. (B) flexibility is out of shape determine ﹕ (ELASTIC STRAIN MEASUREMENT

When fabric suffers effect of fixed negative charge or drawing comes to be worth certainly, can restore after purify bear again be out of shape. The instant can restore be out of shape. Call " urgent flexibility is out of shape " ﹔ is out of shape via what can restore after proper time, call " delay flexibility is out of shape " . Determine general component is the method " calm bear law " with " decide stretchy way " two kinds.

﹕ of calm bear law increases given load to growing the sample of Lo, the time with and lasts proper, measure its length L1, next purify bear, make sample replies, lie between proper time to measure an its length L2. Rate of response of calm bear flexibility follows the compare percentage of L1-L0 for L1-L2 namely. Numerical value heals big, make known one's position stretch response rate has healed.

Deciding stretchy law ﹕ is in the regulation sample initiative tension falls, placing at collet of puissant experiment machine. Clip holds length to be Lo, actuate issues collet, make sample achieves formulary percentage elongation, via proper time, next collet rise time to former, via stipulating time is flabby, measuring below initiative tension again length L2, decide stretchy flexibility to restore to lead for [L0(1+ decides percentage elongation) - L2] decides percentage elongation with Lo(1+ ) percentage. Of knitted fabric of ammoniac black silk ribbon good wear the data that writes function to follow reply force with tensile force of ammoniac black silk ribbon to concern, the curve of meet an emergency of stress, show good lag is characteristic. Reason must consider alertly.

The drawing flexibility of stretch knitted fabric checks international standard and test method:

(Attestation of A) LYCRA SOFT checks from cloth board on scissor 3 " × 8 " strip, next end oversews to end, form 3 " × 3 " cloth annulus, last 1 " outside suture, every cloth board is in straight to ﹑ transverse each equipment 3 cloth annulus. The branch that checks reply work is compared. The loop helps cloth link 3 times on Instron or Zwick drawing machine, and achieves 100% percentage elongation every time (the standard rate of drawing is 1000%/ minute) . When the 3rd times drawing circulates, drawing good luck is calculated automatically reply result (the cent of Work Recovery) is compared (Instron needs to deserve to have special software) , the average that the report tests 3 times. Slope determines: When the 3rd times drawing circulates, comes with drawing 80% reach a reply to be calculated to the fabric tension when 30% percentage elongation slope, tensional value can get from drawing graph or the computer is self-recording.

Slope (Slope)= drawing comes the tension of the fabric when 80% percentage elongation / the response comes the tension of the fabric when 30% percentage elongation

In fabric, if ammoniac black silk ribbon is line abb or gasket (Laid In) , if warp knitting pulls fabric of 902C of great majority of ﹑ of the fabric that abandon Er, reply work is the least 70% ﹔ of ﹕ slope ﹕ ≦ 5.

In fabric, if ammoniac black silk ribbon is to be knitted (Knit In) , be like fabric of 906B of great majority of ﹑ of fabric of warp knitting of cylinder cloth ﹑, reply work is the least 70% ﹔ of ﹕ slope ﹕ ≦ 10.

Fabric wants a direction to achieve above requirement only, and can call Lycra Soft fabric.

(B) is wide / the modular quantity of fabric of narrow cut flexibility checks with percentage elongation (this method of SARA LEE 14) is used at the test wide / fabric of narrow cut flexibility is passed wait for fast drawing machine (the ultimate percentage elongation of CRE) follows pulling force. This method is used at the test wide / fabric of narrow cut flexibility (by natural / man-made flexibility fiber closes minute with other / natural fiber blending and into) modular quantity follows percentage elongation.
