In addition, in order to enable the mask to have the effect of preventing water splashing, water splashing yarns are preferably prevented at the outer sides of the low air resistance area 1 and the high air resistance area 2, and the size and the distribution of coil holes in the area can be adjusted by adjusting the looping proportion of the two yarns, so that the area achieves the balance of performances in the aspects of water splashing prevention and air permeability. Meanwhile, in order to improve wearing comfort, spandex coated yarns are preferable on the inner side of the high-air-resistance area 2. The high-elastic yarn can be selected from spandex coated yarn, PET/PTT bi-component polyester elastic yarn, polypropylene elastic fiber coated yarn and other yarns with relatively good elasticity, and the low-elastic yarn can be selected from polyester DTY, polyester FTY, cotton yarn and other yarns with relatively poor elasticity.
When knitting the low air resistance area 1 of the mask, the high elastic yarn is knitted by a separation needle, and the low elastic yarn is knitted by a full needle; specifically, as shown in fig. 2, the low air resistance region 1 is knitted by a flat knitting machine having a front needle bed and a rear needle bed, and the knitting method is as follows: s1, knitting the outer side surface of a mask by using a high-elastic yarn separation needle on a front needle bed; s2, knitting the outer side surface of one row of mask by using low-elastic yarn full needle on the front needle bed; s3, knitting the outer side surface of one row of mask by using high-elastic yarn spacing needles on the front needle bed, wherein knitting needle positions of the high-elastic yarn spacing needles are staggered with those of the high-elastic yarn spacing needles in s 1; s4, knitting the outer side surface of one row of mask by using low-elastic yarn full needle on the front needle bed; s5, weaving the low air resistance area 1 by taking s1-s4 as a cycle. The knitting mode of the needle separation and the full needle enables two yarns to have different knitting proportions, which is similar to the mode of forming different knitting proportions in the high air resistance area 2, knitting is carried out in a needle separation mode in the figure, namely the knitting proportion is 1:2, if knitting is performed with two needles apart, the stitch ratio is 1:3, the looping ratio may also be 1: 4. 1:5, etc., but the stitch spacing of the spacer needle cannot be too great, otherwise the knitting needle is not easy to eat the thread or even can not knit.
When the high air resistance area 2 of the mask is woven, the high elastic yarns on the outer side are woven by full needles, the low elastic yarns on the outer side are woven by spacer needles, and the high elastic yarns on the inner side connect the inner side and the outer side of the high air resistance area 2 through tuck stitches; specifically, as shown in fig. 3, the high air resistance region 2 is knitted by a flat knitting machine having a front needle bed and a rear needle bed, and the knitting method is as follows: a1, knitting the outer side surface of a one-row mask by using high-elastic yarn full needles on a front needle bed; a2, knitting the inner side surface of one row of mask by using high-elastic yarn spacing needles on the back needle bed; a3, weaving the inner side surface of the one-row mask by using high-elastic yarns and a2 staggered needle spacers on the back needle bed; a4, knitting the outer side surface of the mask by using a low-elastic yarn separation needle on the front needle bed; a5, connecting the outer side surface of the mask and the inner side surface of the mask through a tuck stitch by using high-elastic yarns on the front needle bed and the rear needle bed; a6, knitting the outer side surface of the mask by using high-elastic yarns in a full needle mode on the front needle bed; a7, knitting the inner side surface of one row of mask by using high-elastic yarn spacing needles on the back needle bed, wherein knitting needle positions of the high-elastic yarn spacing needles are staggered with those of the high-elastic yarn spacing mask in a 2; a8, weaving the inner side surface of the one-row mask by using high-elastic yarns and a7 staggered needle spacers on the back needle bed; a9, knitting the outer side surface of one row of mask by using low-elastic yarn spacing needles on the front needle bed, wherein knitting needle positions of the mask are staggered with those of the mask of a 4; a10, connecting the outer side surface of the mask and the inner side surface of the mask by using high-elastic yarns through tuck stitches on the front needle bed and the back needle bed, wherein the knitting needle positions of the high-elastic yarns are staggered with the knitting needle positions in a 5; a11, weaving the high air resistance area 2 by taking a1-a10 as a cycle. By adopting the weaving method, gaps among the coils at the inner side of the high air resistance area 2 can be very small due to shrinkage of the high elastic yarn, so that the air resistance of the area is much higher than that of the low air resistance area, thereby ensuring that most of air flows with the outside through the low air resistance area 1 in the using process of the mask, and the added hot melt yarn can completely fill the gaps among the knitting coils through a later hot pressing process, so that the high air resistance area is absolutely airtight.
In addition, in order to further avoid the influence of mask deformation on the air tightness of the mask when the mask is worn. The high air resistance area 2 is knitted by a flat knitting machine with a front needle bed and a back needle bed, the high air resistance area 2 comprises a low shrinkage area 2-2 and a high shrinkage area 2-1, the high shrinkage area 2-1 corresponds to the chin of a wearer, and the knitting method of the low shrinkage area 2-2 is as follows: a1, knitting the outer side surface of a one-row mask by using high-elastic yarn full needles on a front needle bed; a2, knitting the inner side surface of one row of mask by using high-elastic yarn spacing needles on the back needle bed; a3, weaving the inner side surface of the one-row mask by using high-elastic yarns and a2 staggered needle spacers on the back needle bed; a4, knitting the outer side surface of the mask by using a low-elastic yarn separation needle on the front needle bed; a5, connecting the outer side surface of the mask and the inner side surface of the mask through a tuck stitch by using high-elastic yarns on the front needle bed and the rear needle bed; a6, knitting the outer side surface of the mask by using high-elastic yarns in a full needle mode on the front needle bed; a7, knitting the inner side surface of one row of mask by using high-elastic yarn spacing needles on the back needle bed, wherein knitting needle positions of the high-elastic yarn spacing needles are staggered with those of the high-elastic yarn spacing mask in a 2; a8, weaving the inner side surface of the one-row mask by using high-elastic yarns and a7 staggered needle spacers on the back needle bed; a9, knitting the outer side surface of one row of mask by using low-elastic yarn spacing needles on the front needle bed, wherein knitting needle positions of the mask are staggered with those of the mask of a 4; a10, connecting the outer side surface of the mask and the inner side surface of the mask by using high-elastic yarns through tuck stitches on the front needle bed and the back needle bed, wherein the knitting needle positions of the high-elastic yarns are staggered with the knitting needle positions in a 5; a11, weaving the high air resistance area 2 by taking a1-a10 as a cycle; the knitting method of the high shrinkage zone 2-1 comprises the following steps: b1, knitting rib structures on the front needle bed and the back needle bed by using high-elastic yarns; b2, knitting the inner side surface of one row of mask by using high-elastic yarn spacing needles on the back needle bed, wherein knitting needle positions of the high-elastic yarn spacing needles are staggered with those of the back needle bed in b 1; b3, weaving the high shrinkage zone 2-1 of the high air resistance zone 2 by taking b1-b2 as a cycle; the high air resistance area 2 of the mask is divided into the low shrinkage area 2-2 and the high shrinkage area 2-1, the high shrinkage area 2-1 is positioned at the lower edge of the mask, and the difference of the high shrinkage area and the low shrinkage area in the transverse dimension of the fabric ensures that the mask shell covers the chin of a wearer and generates an arc of a back buckle towards the inner side, thereby better ensuring the coating property of the mask on the chin and improving the air tightness of the mask.
The knitting lines s1-s4, a1-a10 and b1-b2 in the steps above may be continuously knitted into a plurality of lines, for example, 2 lines, 3 lines, 4 lines or 5 lines, and the specific number of lines may be reasonably selected according to the size and shape of the mask, for example, when knitting a low air resistance region, the knitting manner may be: s1, s2 s3, s4.
Ear straps 3 are also connected to the two sides of the mask body, and a metal nose clip is arranged at the upper end of the mask body. The metal nose clip can be put into the idle running of the knitted opening in the gap between the front needle plate and the rear needle plate in the knitting process, the idle running opening is closed through the subsequent knitting or needle turning action, a small opening can be formed in a local knitting or hole picking mode, and the metal strip is manually inserted into the mask shell after the knitting of the mask shell is finished. The ear belt 3 can be woven through two independent yarn mouths while the mask body is woven, and the structure of the ear belt 3 can be selected from knitting structures such as needle-isolating single-sided, double-thread, four-flat idling and the like; the two through passages can be woven on the left side and the right side or the upper side and the lower side of the mask main body by using idle tissues, so that the traditional ear strap ropes can be manually threaded into the passages and sewn at the later stage to realize different fixing methods; because the flat knitting technology has the characteristic of knitting line by line from bottom to top, the traditional method generally uses a needle copying process to transversely and sequentially loop all the loops in order to prevent the loops from being scattered in the last knitting line of the fabric, thereby preventing the loops from being scattered, but the needle copying process often consumes longer knitting time, thereby increasing the knitting cost; in this scheme, the gauze mask main part is finished using the high-elastic yarn that adds the hot melt yarn, such as rubber yarn or the high-elastic yarn of mentioning and is woven plain needle single face structure, later is finished weaving, carries out hot pressing design processing to it, and the thermal fuse melts the back and solidifies to the coil that will end the line is mutual to be adhered fixedly, the turn-up characteristic of single face structure is recycled, the coil that ends the line inwards curls, and not directly expose at gauze mask shell surface, consequently at daily in-process of using, does not have the risk that the coil is taken off and is scattered.
After knitting, placing the mask into a mold for heat setting treatment, and after the thermal fuse is sufficiently melted, so as to increase the stability of the shape and the shape retention, thereby ensuring that the lower part of the mask can be attached to the jaw skin, covering the mouth and the nose of a wearer in the middle of the mask for receiving the filter material, keeping a certain distance between the filter material and the mouth and the nose, and improving the wearing comfort; the upper part of the mask covers the nose bridge area from the tip of the nose upwards, so that the tightness is ensured and the nose bridge is not pressed.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
