A knitted mask as shown in fig. 1, which comprises a mask body comprising a low air resistance region 1 and a high air resistance region 2; low air-resistor district 1 is located gauze mask main part middle part and the filter media covers low air-resistor district 1, the filter media of formula of pasting can be chooseed for use to the filter media, low air-resistor district 1 is used for covering the person of wearing mouth nose region, low air-resistor district 1 has chooseed transform single face structure for use, low air-resistor district 1 weaves through two kinds of different elastic yarns and forms, elasticity is high for high stretch yarn in two kinds of different elastic yarns, elasticity is low for low stretch yarn, low stretch yarn still adds hot melt yarn, when weaving, hot melt yarn weaves with the mode of plating, hot melt yarn and low stretch yarn's ratio can be for 1: 1, two yarns with different elasticity have different loop forming ratios; high air-resistor district 2 is located around low air-resistor district 1, and high air-resistor district 2 is the two-sided structure of variant, and its outside is woven through two kinds of different elastic yarns and is formed, and two kinds of different elastic yarns are high-elastic yarn and low-elastic yarn, and low-elastic yarn still adds hot melt yarn, and two kinds of different elastic yarns have different looping proportions, and its inside is woven through high-elastic yarn and is formed. In addition, in order to make the mask have the effect of preventing water splashing, the water splashing prevention yarns are preferably selected outside the low air resistance region 1 and the high air resistance region 2, and the size and the distribution of the coil holes in the region can be adjusted by adjusting the looping ratio of the two yarns, so that the performance of the region can be balanced in terms of water splashing prevention and air permeability. Meanwhile, in order to improve the wearing comfort, spandex-covered yarns are preferably selected on the inner side of the high air resistance region 2. The high-elasticity yarns can be selected from yarns with relatively good elasticity, such as spandex coated yarns, PET/PTT bi-component polyester elastic yarns, polypropylene elastic fiber wrapped yarns and the like, and the low-elasticity yarns can be selected from yarns with relatively poor elasticity, such as polyester DTY (draw textured yarn), polyester FTY (fiber-to-the-filament yarn), cotton yarns and the like.
When a low air resistance area 1 of the mask is knitted, high-elasticity yarns are knitted by adopting needle separation, and low-elasticity yarns are knitted by adopting full needles; specifically, as shown in fig. 2, the low air resistance zone 1 is knitted by a flat knitting machine having a front needle bed and a back needle bed, and the knitting method is: s1, knitting the outer side of the gauze mask on the front needle bed by using high-elastic yarn needles in a separating way; s2, knitting the outer side face of the gauze mask in one row with a low-elasticity yarn full needle on the front needle bed; s3, knitting the outer side of the mask in one row on the front needle bed by using high-elastic yarn needles, wherein the knitting needle position of the front needle bed is staggered with the knitting needle position of s 1; s4, knitting the outer side face of the gauze mask in one row with a low-elasticity yarn full needle on the front needle bed; s5, weaving the low air resistance region 1 with s1-s4 as a cycle. The knitting mode of the alternate needle and the full needle enables the two yarns to have different looping proportions, which is similar to the mode of forming different looping proportions in the high air resistance area 2, and the knitting mode of the alternate needle is adopted in the drawing, namely, the looping proportion is 1: 2, if knitting is carried out at every two needles, the knitting ratio is 1: and 3, the looping ratio can also be 1: 4. 1: 5, but the stitch interval of the needle separation is not too much, otherwise, the knitting needle is not easy to eat the thread and even can not knit.
When the high air resistance area 2 of the mask is knitted, high-elasticity yarns on the outer side are knitted by full needles, low-elasticity yarns on the outer side are knitted by separating needles, and the high-elasticity 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-lock zone 2 is knitted by a flat knitting machine having a front needle bed and a back needle bed, and the knitting method is: a1, knitting the outer side face of the gauze mask on the front needle bed by using high-elastic yarn full needles; a2, knitting the inner side of the gauze mask on one row of back needle bed by high elastic yarn needles; a3, knitting the inner side of the gauze mask in one row by using high elastic yarn and a2 staggered needles on the back needle bed; a4, knitting the outer side face of the gauze mask in one row on a front needle bed by using low elastic yarns at intervals; a5, connecting the outer side surface of the mask and the inner side surface of the mask by high elastic yarn through tuck stitch; a6, knitting the outer side face of the gauze mask on the front needle bed by using high-elastic yarn full needles; a7, knitting the inner side of the gauze mask on one row at the back needle bed by high elastic yarn needle separation, wherein the knitting needle position is staggered with the knitting needle position in a 2; a8, knitting the inner side of the gauze mask in one row by using high elastic yarn and a7 staggered needles on the back needle bed; a9, knitting the outer side surface of the gauze mask in one row by using low elastic yarn needles at intervals on the front needle bed, wherein the knitting needle position is staggered with the knitting needle position of a 4; a10, connecting the outer side surface and the inner side surface of the mask through tuck stitch by high elastic yarn for front and back needle beds, wherein the knitting needle position of the high elastic yarn is staggered with the knitting needle position in a 5; a11, weaving the high air resistance region 2 by taking a1-a10 as a cycle. By adopting the weaving method, the gaps between the coils at the inner side of the high air resistance area 2 can be very small due to the shrinkage of the high-elastic yarns, so that the air resistance of the area is much higher than that of the low air resistance area, thereby ensuring that most of gas circulates with the outside through the low air resistance area 1 in the using process of the mask, and the added hot-melt yarns can completely fill the gaps between the knitted coils through the later hot-pressing process, thereby ensuring that the high air resistance area is absolutely airtight.
In addition, in order to further avoid the influence of the deformation of the mask 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 contraction area 2-2 and a high contraction area 2-1, the high contraction area 2-1 corresponds to the position of the chin of a wearer, and the low contraction area 2-2 is knitted by the following method: a1, knitting the outer side face of the gauze mask on the front needle bed by using high-elastic yarn full needles; a2, knitting the inner side of the gauze mask on one row of back needle bed by high elastic yarn needles; a3, knitting the inner side of the gauze mask in one row by using high elastic yarn and a2 staggered needles on the back needle bed; a4, knitting the outer side face of the gauze mask in one row on a front needle bed by using low elastic yarns at intervals; a5, connecting the outer side surface of the mask and the inner side surface of the mask by high elastic yarn through tuck stitch; a6, knitting the outer side face of the gauze mask on the front needle bed by using high-elastic yarn full needles; a7, knitting the inner side of the gauze mask on one row at the back needle bed by high elastic yarn needle separation, wherein the knitting needle position is staggered with the knitting needle position in a 2; a8, knitting the inner side of the gauze mask in one row by using high elastic yarn and a7 staggered needles on the back needle bed; a9, knitting the outer side surface of the gauze mask in one row by using low elastic yarn needles at intervals on the front needle bed, wherein the knitting needle position is staggered with the knitting needle position of a 4; a10, connecting the outer side surface and the inner side surface of the mask through tuck stitch by high elastic yarn for front and back needle beds, wherein the knitting needle position of the high elastic yarn is staggered with the knitting needle position in a 5; a11, weaving the high air resistance region 2 by taking a1-a10 as a cycle; the weaving method of the high shrinkage zone 2-1 comprises the following steps: b1, knitting rib stitch with high elastic yarn on front and back needle beds; b2, knitting the inner side of the mask on one row by using high-elastic yarn needles on the back needle bed, wherein the knitting needle position of the high-elastic yarn needles is staggered with the knitting needle position of the back needle bed in b 1; b3, weaving a high contraction area 2-1 of the high air resistance area 2 by taking b1-b2 as a cycle; the high air resistance area 2 of the mask is divided into a low contraction area 2-2 and a high contraction area 2-1, the high contraction area 2-1 is located at the lower edge of the mask, and the difference of the high contraction area and the low contraction area in the transverse size of the fabric enables the part of the mask shell covering the chin of a wearer to generate a radian buckled inwards, so that the wrapping performance of the mask on the chin is better guaranteed, and the air tightness of the mask is improved.
One knitting line mentioned in s1-s4, a1-a10 and b1-b2 of the above steps can also be continuously knitted for multiple lines, for example, 2, 3, 4 or 5 lines are continuously knitted, and the specific number of continuously knitted lines can be reasonably selected according to the size and shape of the mask, for example, when knitting a low air resistance region, the knitting mode can be: s1, s1, s1, s2, s2, s3, s3, s3, s4, s 4.
The two sides of the mask body are also connected with ear belts 3, and the upper end of the mask body is provided with a metal nose clip. The metal nose clip can be put into a woven opening to idle in the gap between the front needle plate and the rear needle plate in the weaving process, the idle opening is closed through subsequent weaving or needle turning actions, a small opening can be formed in a local weaving or hole picking mode, and a metal strip is manually inserted into the small opening after the weaving of the mask shell is finished. The ear belt 3 can be simultaneously knitted by two independent yarn nozzles while the mask body is knitted, and the structure of the ear belt 3 can be selected from knitting structures such as a separating needle single surface, double threads, four flat idle rotation and the like; the left side and the right side or the upper side and the lower side of the mask main body can be woven into a channel with two through ends by idle running tissues, so that the traditional ear belt rope can be manually threaded into the channel at the later stage and sewn to realize different forms of fixing methods; because the flat knitting technology has the characteristic of knitting line by line from bottom to top, conventionally, in order to prevent the stitch from raveling, the last knitting line of the fabric is generally used, and an overlock needle process is used for transversely and sequentially snaring all stitches, so that the raveling of the stitches is prevented, but the overlock needle process usually consumes longer knitting time, so that the knitting cost is increased; according to the scheme, the mask body is finished by knitting a plain single-sided structure with high-elasticity yarns added with hot-melt yarns such as rubber band yarns or the high-elasticity yarns, then finishing knitting, carrying out hot-press forming treatment on the plain single-sided structure, solidifying the molten hot-melt yarns, so that the coils of the finished row are mutually adhered and fixed, and the coils of the finished row are curled inwards by utilizing the curling characteristic of the single-sided structure and are not directly exposed on the surface of the mask shell, so that the risk of coil falling off is avoided in the daily use process.
After weaving, putting the mask into a mold for heat setting treatment, and after the thermal fuse is fully melted, increasing the stability of the shape and improving the shape retention property, so as to ensure that the lower part of the mask can be attached to the skin of the lower jaw; the nose bridge area from the nose tip to the top is covered above the mask, so that the air tightness is ensured, and meanwhile, the nose bridge is not stressed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
