Structural features: Weft-heavy flat or square weave is used, with combed fine yarns as double warps interwoven with thicker weft yarns. Style features: easy to wash and quick to dry, soft to the touch, good hygroscopicity, comfortable to wear, and natural luster.
Main uses:
1. Plaid Oxford cloth, specially used for making bags.
2. Nylon Oxford cloth, mainly used to make flood prevention supplies.
3. Fully elastic Oxford cloth, mainly used for making bags.
4. Teague Oxford cloth, mainly produces various bags.
5. Weft Oxford cloth, mainly used to make various bags.
Temperature: 190 degrees Celsius
Time: 30s
Purpose: Eliminate fabric wrinkles and improve fabric dimensional stability.
Alkali reduction processing:
Drugs: 30% caustic soda 5g/L
Liquor ratio: 1:50
Accelerator (1227)1g/L
Refining agent: 0.5g/L
Temperature: 100 degrees Celsius
Time: 60min
Purpose: To give the fabric a soft feel, soft luster, and improve hangability and water retention.
Performance testing:
Desizing rate:
The weight of the fabric before desizing is 22g, and the weight of the fabric after desizing is 21.72g
Desizing rate = (fabric weight before desizing – fabric weight after desizing)/
Fabric weight before desizing×100%
Desizing rate=(22-21.72)/22×100%=1.27%
Reduction rate:
The weight of the fabric before alkali reduction is 9.48g, and the weight of the fabric after alkali reduction is 9.08g
Weight reduction rate = (fabric weight before alkali weight reduction – fabric weight after alkali weight reduction)/fabric weight before alkali weight reduction × 100%
Alkali reduction rate = (9.48-9.08)/9.48×100%=4.22%
Dimensional stability:
Shrinkage:
Shrinkage before heat setting = (10-9.525)/10×100%=4.75%
Shrinkage after heat setting = (10-9.945)/10×100%=0.55%
The shrinkage rate after setting is obviously smaller than that before heat setting, so the fabric after setting is relatively stable. htK
