Embodiment 1

[0023] The basalt fiber chenille knitted fabric of this embodiment includes a basalt fiber chenille knitted fabric formed by crocheting a basalt fiber chenille yarn with a diameter of 0.7 cm through a flat knitting machine, the basalt fiber chenille yarn It includes two parts: core thread and feather yarn. The surface of the core thread and feather yarn is coated with polyimide coating by spraying process. The material of the feather yarn is basalt fiber, and the fineness of the feather yarn is 21Nm; the core yarn is Two strands, the fineness of each strand is 24Nm, and the core thread is made of basalt fiber. After the core thread is twisted, the feather yarn is sandwiched between the two core threads. The twisting degree of the core thread is 590 twists / m. The axial density of the feather yarn is 390 yarns / cm. Using the basalt fiber chenille yarn as the raw material, the warp and weft knitting machine is crocheted into an 8-needle plain basalt fiber chenille knitted fabric wit...

Embodiment 2

[0025] The basalt fiber chenille knitted fabric of the present embodiment includes a basalt fiber chenille knitted fabric formed by crocheting a basalt fiber chenille yarn with a diameter of 0.3 cm through a large circular machine. The basalt fiber chenille yarn includes The core thread and the feather yarn are two parts. The surface of the core thread and feather yarn is coated with a polyimide coating by a spraying process. The material of the feather yarn is basalt fiber, and the fineness of the feather yarn is 50Nm; the core yarn is two parts. Each strand has a fineness of 60Nm. The core thread is made of quartz glass fiber. After the core thread is twisted, the feather yarn is sandwiched between the two core threads. The twisting degree of the core thread is 10 twists / meter. The axial density of the feather yarn is 200 pieces / cm. Using basalt fiber chenille yarn as raw material, it is crocheted into a 10-needle ribbed basalt fiber chenille knitted fabric with a width of 1.6...

Embodiment 3

[0027] The basalt fiber chenille knitted fabric of this embodiment includes a basalt fiber chenille knitted fabric formed by crocheting a 0.2cm basalt fiber chenille yarn by a crochet machine, and the basalt fiber chenille yarn includes a core Two parts of thread and feather yarn, the surface of the core thread and feather yarn is coated with thermosetting epoxy resin coating using a dip coating process, the material of the feather yarn is a mixed yarn of basalt fiber and quartz glass fiber, and the fineness of the feather yarn is 100Nm; The core thread is two strands, each strand has a fineness of 100Nm, and the core thread is made of a mixed yarn of polytetrafluoroethylene fiber and polyimide fiber. The core thread is twisted to clamp the feather yarn In the middle of the two core yarns, the twisting twist of the core yarn is 1000 twists / m, and the axial density of the feather yarn is 10000 yarns / cm. Using the basalt fiber chenille yarn as the raw material, it is crocheted int...

Abstract

The invention discloses a basalt fiber chenille knitted fabric. The basalt fiber chenille knitted fabric is formed by crocheting basalt fiber chenille yarns through knitting equipment, wherein the basalt fiber chenille yarns comprise core yarns and camlet, the camlet is made from basalt fibers or a combination yarn of basalt fibers and one or more of quartz glass fibers, high silica glass fibers, aluminum silicate fibers, polyamide-imide fibers, polyether-ether-ketone fibers, polyphenylene sulfide fibers, polysulfoneamide fibers, poly(p-phenylene benzobisoxazole) fibers, polybenzimidazole fibers, polytetrafluoroethylene fibers, polyimide fibers and aramid fibers; each core yarn is formed by two piled yarns, and the camlet is clamped between every two core yarns which are twisted. The basalt fiber chenille knitted fabric processed by a knitting machine has the advantages that space gaps among the yarns are large, air resistance is small, and thus the air filtering efficiency can be improved.

Description

technical field [0001] The patent of the invention relates to a knitted fabric for air purification, in particular to a basalt fiber chenille knitted fabric. Background technique [0002] The core thread of the chenille yarn in the prior art is twisted with acrylic yarn as a raw material, and the feather yarn is cut into short feathers with viscose yarn as a raw material, which are widely used in the fields of home textiles and knitted garments. The fabric that adopts common chenille yarn to weave generally gets its decorative effect more, and its comfortableness aspect is relatively poor. Rarely used for air filtration purposes. [0003] After China experienced the "soot-type pollution" brought about by the industrial revolution in the 18th century and the "photochemical smog pollution" brought about by the petroleum and automobile industries in the 19th century, modern people are experiencing "severe PM2.5-type smog" with Chinese characteristics. The third pollution peri...
