Appendix A

(Normative) Elastic recovery and compression test method bulkiness A.1 Principle After opening the sample, hand-made cotton net, plus light load and heavy load respectively cotton online determination of cotton net height, respectively, By this calculation fiber bulkiness and compression elastic recovery. A.2 equipment and tools A.2.1 opener Employs a large work rolls and a few small work rolls at the same time opening, low speed (1400r/min) work, It enables the fiber to maximize the opening, slip and curl not damage the fiber, but also make fluffy fibers to achieve the desired effect. A.2.2 fiber bulkiness, elastic compression tester Requires a high degree of measurement error of ± 0.5mm, with a load is applied along with the compact A [10cm × 10cm perspex block (Includes handle, handle length is appropriate in order to operate), the quality of 60g, tolerance ± 1%] and compact B [mass of 500g, Tolerance of ± 1% stainless steel block (including the handle, the length of the handle to facilitate operation is appropriate)]. A.2.3 Balance Minimum scale value 10mg. A.3 Air conditioning and testing standards Temperature (20 ± 2) ℃, relative humidity (65 ± 5)%. A.4 sample and its preparation A.4.1 Sampling A.4.1.1 laboratory samples taken by the 500g GB/T 14334 regulations. A.4.1.2 randomly selected from the laboratory test sample chamber evenly representative sample 200g, conducted in accordance with the humidity test regulations, The sample to reach equilibrium moisture. Regain the laboratory test sample in moisture regain or less, may not necessarily be the humidity. A.4.2 Sample Preparation A.4.2.1 instrument according to instructions for adjustment of process parameters open pine machine. A.4.2.2 Test before the opening empty running, check the machine whether the abnormal sound. A.4.2.3 from the humidity balance of the sample taken at random sample of about 50g, spread evenly on the conveyor opener, open opener master power switch, After the host to enter the work state (reach the rated rotational speed) to open the curtain opener conveying power switch, the fiber opening. A.4.2.4 fiber opener and then click Close blinds and delivery mains switch after the opening end. A.5 Test program A.5.1 certain amount of loose fibers in the sample after opening the fibers on the balance, weighed (5 ± 0.1) g, Gently into 4 parts to 5 parts of an area of about 10cm × 10cm cotton net, then gently placed in a bulky instrument characteristics. After standing 5min, slowly down compacts A (light load 60g) Do not apply any impact, after reading the height h1 1min sample (accurate to 0.5mm). A.5.2 on the basis of light load slowly down the compact B (In this case heavy load is 560g), after reading the height h2 1min (accurate to 0.5mm). A.5.3 removal of heavy-duty, standing 3min, then slowly down a light load, after reading the height h3 1min (accurate to 0.5mm). A.6 Calculation A.6.1 bulkiness V1, bulkiness V2, V3 bulkiness and compressive elasticity (reply) E ratio by the formula (A.1) ~ formula (A.4) is calculated. V1 = Ah1G (A.1) V2 = Ah2G (A.2) V3 = Ah3G (A.3) E = h3-h2h1-h2 (A.4) Where. V1 --- fiber bulkiness under light load is applied, in units of grams per cubic centimeter (cm3/g); A --- model area, in units of square cm (cm2 for); Sample height h1 --- under a light load is applied, in centimeters (cm); G --- sample mass, in grams (g); V2 --- fiber bulkiness under heavy action, cubic centimeters per gram (cm3/g); Sample height h2 --- under heavy role in centimeters (cm); After removing the fiber V3 --- heavy, bulkiness under light load is applied, in units of grams per cubic centimeter (cm3/g); After the removal of heavy h3 --- balance 3min, plus the height of the sample under a light load is applied, in centimeters (cm); E --- fiber compressive elasticity (reply) rate,%. A.6.2 V1, V2, V3, E represents the value of the two assays for test results. After calculating to one decimal place, according to GB/T 8170 provisions of rounding to the nearest whole number. ......
