In this embodiment, the step of double-sided weaving in S5 specifically includes:
placing nanofiber base yarns and pure ion antibacterial base yarns on a preset knitting weft knitting circular knitting machine, adjusting a dial of the knitting weft knitting circular knitting machine and knitting needles on a needle cylinder to form loops respectively, hooking the pure ion antibacterial base yarns by the knitting needles on the needle cylinder, and enclosing yarn loops with the nanofiber base yarns hooked by the dial;
and (3) the knitting needles on the dial are ejected, and the knitting needles on the needle cylinder are controlled to be stretched and adjusted downwards, so that the pure ion antibacterial ground yarns hooked by the needle cylinder are connected with the nanofiber ground yarns hooked by the dial, and the double-sided fabric is formed.
The method comprises the steps of setting out knitting needles on a dial, simultaneously controlling the knitting needles on a needle cylinder to stretch and adjust downwards, enabling pure ion antibacterial ground yarns hooked by the needle cylinder to be connected with nanofiber ground yarns hooked by the dial, and forming double-sided fabric, wherein the method further comprises the following steps:
and (3) adjusting the proportion of the upper needle to the lower needle of the weft knitting circular knitting machine to be 1:2, forming a pit strip effect by adopting yarns through the looping of the upper needle and the looping of the lower needle in a single way, setting the bottom surfaces of the double-sided fabric and the breathable ultraviolet-resistant fabric to be 2:1 of the proportion of transverse loops, and then carrying out mixed spinning to obtain the sun-proof garment to be colored.
The step of performing mixed spinning after setting the bottom surfaces of the double-sided fabric and the breathable ultraviolet-resistant fabric to be 2:1 of the transverse coil proportion specifically comprises the following steps:
taking the double-sided fabric as a first coil, and taking the breathable ultraviolet-resistant fabric as a second coil;
after the first coil course is discharged, a lower-disc-needle tuck knitting needle and an upper-disc-needle loop knitting needle of a weft knitting machine are used for simultaneously knitting the first coil in a loop forming mode, and weft yarns to be stretched are obtained, wherein when the weft knitting machine performs loop forming knitting, the lower-disc-needle tuck knitting needle course but does not form loops, and the upper-disc-needle loop knitting needle course forms a loop course;
after the second coil is vertically discharged, performing loop knitting on the second coil by using a lower-disc needle loop-collecting knitting machine of a weft knitting machine to obtain warp yarns to be stretched, wherein the upper-disc needle loop of the second coil is not knitted, and the proportion of the loop knitting of the lower-disc needle loop of the second coil to the loop knitting of the needle disc of the first coil is 1:1;
and passing the weft yarn to be stretched through a preset stretching device from the upper part of the textile machine, and simultaneously passing the warp yarn to be stretched through the stretching device from the lower part of the textile machine, so that the weft yarn to be stretched and the warp yarn to be stretched are interwoven to form a double-sided fabric.
Specifically, the process of converting the nanofiber base yarn and the pure ion antibacterial base yarn from materials into the base yarn is specifically as follows:
pretreating the selected nanofiber material and the pure ion antibacterial material, wherein the pretreatment process comprises washing, bleaching and dyeing processes so as to remove stains and adjust the color;
determining the specification of the base yarn according to the weaving requirement, wherein the specification comprises parameters of warp yarn density, weft yarn density and fabric width;
the two fiber materials are condensed and twisted into yarn in an electrostatic field, and the fiber is condensed and twisted in a spinning cup rotating at high speed by utilizing air current to output the yarn, so that the fabric structure of the base yarn is formed.
The specific process of the mixed spinning in the S1 comprises the following steps:
preparing a fabric: preparing cotton fabric and hemp fabric, and ensuring that the two fabrics can meet the required quality requirement and proportion;
cleaning and pretreatment: the cotton fabric and the hemp fabric are cleaned and pretreated to remove impurities, stains and other nonwoven materials, and the cleaning, bleaching and rinsing processes can be performed;
spinning: feeding the cotton fabric and the hemp fabric after cleaning and pretreatment into a spinning machine, and stretching and twisting the fibers under the action of the spinning machine to form spun yarns;
combing: combing the spinning yarn to remove short fibers, impurities and crude fibers, and finishing the spinning yarn by a carding machine or a carding machine;
drawing treatment: drawing the combed yarn, wherein the drawing can be performed to form a plurality of yarns in parallel so as to improve the stability and uniformity of the yarn;
winding: and winding the yarn subjected to drawing treatment so as to be used in the subsequent process, wherein the winding can be finished through a spindle machine or a winding machine, and the mixed spinning is finished.
The warp and weft knitting adopted in the double-sided weaving process has the following beneficial effects:
increasing the stability of the fabric: by simultaneously warp knitting and weft knitting, the weft and warp structures of the fabric can be interwoven, the stability and uniformity of the fabric are improved, deformation and distortion of the fabric are reduced, and the dimensional stability of the fabric is improved;
increasing the thickness and texture of the fabric: the combination of warp knitting and weft knitting can form multiple layers of yarn interweaving in the fabric, so that the thickness and texture of the fabric are increased, the fabric is plump and soft, and the fabric has better touch feeling;
increasing the diversity of designs: the double-sided weaving of warp knitting and weft knitting can form different patterns and texture effects on two surfaces of the fabric, which provides more creation space for design style and can create appearance with contrast effect or diversity;
enhancing the functionality of the fabric: by knitting different types of yarns and fabrics through warps and wefts, various functions can be given to the fabric, for example, in sun-proof clothes, the different yarns of warp knitting and weft knitting can combine the functions of air permeability, ultraviolet resistance, quick drying and the like, and comprehensive protective performance is provided.
The effect of defining a warp density of 50/cm and a weft density of 60/cm in S2 is:
conventional textiles typically define a warp/weft density of between 20 and 40 (8 to 16) per inch, while defining a warp density of 50 and a weft density of 60 per cm differs in that the density of the sun-protective garment can be varied by controlling the warp and weft, which can result in a tighter and more uniform sun-protective garment, which helps to increase the strength and durability of the fabric, reduces the slackening and deformation of the yarns, and makes the fabric more firm and stable; meanwhile, the fineness and smoothness of the sun-proof clothes can be improved due to the higher warp density and weft density, the surface of the cloth is smoother, the texture is softer and more comfortable, and the sun-proof clothes has high-quality touch feeling and appearance; and proper warp density and weft density can provide moderate air permeability while maintaining fabric tightness, which is helpful for air circulation and moisture discharge, improves air permeability and comfort of the sun-proof garment, and reduces stuffy feeling and moist feeling; the higher warp density and weft density can increase the coverage area and density of the sun-proof clothes, so that the protection capability of the sun-proof clothes is improved, the compact structure of the sun-proof clothes can effectively prevent external sunlight, wind sand, dust and the like from irritating and damaging the skin, and a better protection effect is provided;
the reason why the warp density and the weft density are not continuously improved is that: the high density of warp and weft means that more yarns are used to weave the same area of fabric, thus increasing the total weight of the sun-protective garment, which may make the sun-protective garment feel heavy when worn, less light and comfortable; moreover, the too high warp and weft densities can lead the fabric to be more compact, reduce the air permeability of the fabric, possibly lead the body heat to accumulate in the clothes and not be easy to be emitted out, thereby affecting the comfort of the wearer; at the same time, the high density of warp and weft may limit the elasticity and stretchability of the sun-proof garment, making it lack of sufficient flexibility, which may affect the wearing comfort and freedom of movement of the sun-proof garment; and the high density of warp and weft requires more yarn input and more complex textile processes, which may increase production costs, ultimately reflected in the price of the sun-protective garment, which has a counter effect for both the purchaser and the producer.
The normal temperature coating agent of S3 is used in the sun-proof clothes, and can have the following effects:
