Embodiment 1

[0047] A kind of weaving method of tubular seamless warp knitting spacer shield, described method is on double-needle cylinder warp knitting machine ( figure 1 The above) weaving; the double-needle cylinder warp knitting machine includes 6 circular bars, and the 6 circular bars are arranged above the knitting needles from the outside to the inside, which are respectively the bars GB1, Bar GB2, bar GB3 and bar GB4, bar GB5, and bar GB6 located above the inner needle cylinder.

[0048] The double-cylinder warp knitting machine is composed of circular guide needles and two needle cylinders. On the basis of the single-cylinder circular warp knitting machine, a circular needle cylinder is added inside the needle cylinder, and the outer and inner needle cylinders are respectively called It is the outer needle cylinder and the inner needle cylinder; the distance between the two needle cylinders is 2-4mm; there are 6 circular combs arranged above the needle cylinder, which are GB1, GB...

Abstract

The invention discloses a cylindrical seamless warp-knitted interval protective cover and a weaving method thereof, and belongs to the technical field of warp-knitted fabric weaving. According to the weaving method of the cylindrical seamless warp-knitted spacer fabric, the cylindrical seamless warp-knitted spacer fabric is woven on a double-needle-cylinder warp knitting machine; the double-needle-cylinder warp knitting machine includes six annular guide bars which are sequentially arranged above a knitting needle from outside to inside, namely a guide bar GB1, a guide bar GB2 and a guide bar GB3 which are located on the upper portion of an outer needle cylinder and a guide bar GB4, a guide bar GB5 and a guide bar GB6 which are located on the upper portion of an inner needle cylinder. The double-needle-cylinder warp knitting machine is adopted for knitting, the special needle cylinder configuration and yarn guide needle arrangement mode is achieved, and the warp knitting seamless fabric with the structural effect and the functional effect is achieved; by utilizing the special configuration of the needle cylinders and a yarn guide needle, the inner side and the outer side of the fabric are of a cylindrical structure and are woven into a whole; and the inner side fabric and the outer side fabric are both of a mesh structure and are in one-to-one correspondence in position, and a tedious hole aligning procedure is not needed.

Description

technical field [0001] The invention relates to a tubular seamless warp-knitted spacer cover and a weaving method thereof, belonging to the technical field of warp-knitted fabric weaving. Background technique [0002] The protective cover has the functions of dust prevention and protection, and is usually made of double-needle bed warp-knitted spacer fabric, which is applied to devices that need protection, such as net covers covering cylindrical objects such as stereos and cups. The double-needle bed warp-knitted spacer fabric is a warp-knitted fabric that connects two independent surface tissues through the spacer yarn of the middle layer. It has a three-dimensional structure and can play a certain supporting role. Taking the cylindrical stereo as an example, its 360° no dead angle playback feature is loved by the majority of consumers. Due to the improvement of people's aesthetic level, there are higher requirements for the appearance of cylindrical audio products, and t...
