Abstract
A light-weight high-strength fabric for fencing protective clothing uses UHMWPE fibers with fiber number of 360-420 D and high-strength terylene silks with fiber number of 460-540 D as raw materials. The fabric is prepared through the steps of batching, twisting, weaving, and after-treatment. The resulting fabric has less defects due to improvements in fabric formula and weaving techniques, etc. The puncture strength of the fabric can reach 3300 N, and the mass per unit area can be reduced to 600 g/m2.
Claims8
A preparation process of a fabric comprising:
- Step (1):
- selecting a UHMWPE fiber with a fiber number of 360-420 D and terylene silk with a fiber number of 460-540 D as raw materials;
- Step (2):
- twisting the UHMWPE fiber and the terylene silk at a number of twist of 70-100 T/m to form a yarn, wherein a breaking strength of a single strand of the UHMWPE fiber is 15-20 kg, and a breaking strength of a single strand of the terylene silk is 6-8 kg;
- Step (3):
- knitting the yarn from Step (2) using a double-side circular knitting machine to form a fabric,
- wherein a needle array for the knitting machine is
- wherein, A and B represent two kinds of knitting needles having different needle butts, the needles above the horizontal line represent dial knitting needles, and the needles below the horizontal line represent cylinder knitting needles;
- wherein a triangle array for the knitting machine is as shown in the following table:

- wherein knit cam “∧” represents that the corresponding knitting needle knits is at a full stitch,
- tuck cam “Π” represents that the corresponding knitting needle knits is at a half stitch,
- flat cam “-” represents that the corresponding knitting needle does not participate in knitting,
- the knitting raceways of A and B are different, and
- numbers 1 to 8 represent the number of roads of feeding yarn;
- and
- Step (4):
- successively subjecting the fabric obtained from Step (3) to bleaching, drying, treating with a soft liquid, drying, and sizing.
