A preparation process of a fabric for fencing protective clothing where UHMWPE fibers and high-strength terylene - registered trademark for synthetic polyester - silks are used as raw materials, characterized in that it comprises the following steps: A) Batching UHMWPE fibers with fiber number of 40 tex to 46.67 tex (360-420 denier) and high-strength terylene silks with fiber number of 51.11tex to 60 tex (460-540 denier) are selected as raw materials; B) Twisting The UHMWPE fibers are twisted and the terylene silks are twisted, and the degree of twist is controlled to be 70-100 T/m; After the twisting processing, the breaking strength of single UHMWPE fiber is 147.15 to 196.2 N (15 to 20 kg); and the breaking strength of single terylene silk 58.86 to 78.48 N (6 to 8 kg); C) Weaving Weaving is performed by using a double-side circular knitting machine; The needle array is as follows: wherein, A and B represent two kinds of knitting needle with different needle butt, the needles upper to the horizontal line represent dial knitting needles, and the needles nether to the horizontal line represent cylinder knitting needles; The triangle array is as shown in the following table: wherein, knit cam " Λ" represents that the knitting needle joins in the weaving operation in the manner of full stitch, tuck cam "Π" represents that the knitting needle joins in the weaving operation in the manner of half stitch, flat cam "-" represents that the knitting needle does not join in the weaving operation, the knitting raceways of "A" and "B" is different, and the number "1-8" represent the roads of feeding yarn; D) After-treatment Successively, the as-obtained fabric in step C) is bleached, dried, treated by a soft liquid, then dried and sized. A) Batching UHMWPE fibers with fiber number of 40 tex to 46.67 tex (360-420 denier) and high-strength terylene silks with fiber number of 51.11tex to 60 tex (460-540 denier) are selected as raw materials; B) Twisting The UHMWPE fibers are twisted and the terylene silks are twisted, and the degree of twist is controlled to be 70-100 T/m; After the twisting processing, the breaking strength of single UHMWPE fiber is 147.15 to 196.2 N (15 to 20 kg); and the breaking strength of single terylene silk 58.86 to 78.48 N (6 to 8 kg); The UHMWPE fibers are twisted and the terylene silks are twisted, and the degree of twist is controlled to be 70-100 T/m; After the twisting processing, the breaking strength of single UHMWPE fiber is 147.15 to 196.2 N (15 to 20 kg); and the breaking strength of single terylene silk 58.86 to 78.48 N (6 to 8 kg); C) Weaving Weaving is performed by using a double-side circular knitting machine; The needle array is as follows: wherein, A and B represent two kinds of knitting needle with different needle butt, the needles upper to the horizontal line represent dial knitting needles, and the needles nether to the horizontal line represent cylinder knitting needles; The triangle array is as shown in the following table: wherein, knit cam " Λ" represents that the knitting needle joins in the weaving operation in the manner of full stitch, tuck cam "Π" represents that the knitting needle joins in the weaving operation in the manner of half stitch, flat cam "-" represents that the knitting needle does not join in the weaving operation, the knitting raceways of "A" and "B" is different, and the number "1-8" represent the roads of feeding yarn; Weaving is performed by using a double-side circular knitting machine; The needle array is as follows: wherein, A and B represent two kinds of knitting needle with different needle butt, the needles upper to the horizontal line represent dial knitting needles, and the needles nether to the horizontal line represent cylinder knitting needles; The triangle array is as shown in the following table: wherein, knit cam " Λ" represents that the knitting needle joins in the weaving operation in the manner of full stitch, tuck cam "Π" represents that the knitting needle joins in the weaving operation in the manner of half stitch, flat cam "-" represents that the knitting needle does not join in the weaving operation, the knitting raceways of "A" and "B" is different, and the number "1-8" represent the roads of feeding yarn; D) After-treatment Successively, the as-obtained fabric in step C) is bleached, dried, treated by a soft liquid, then dried and sized.
