[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0024] The present application provides an environmentally friendly knitted fabric that is cool and smooth. The environmentally friendly knitted fabric has a double-layer structure in the thickness direction, including a surface yarn, a middle layer and a bottom layer yarn; the surface of the surface yarn and the bottom layer yarn both have the same jacquard structure;

[0025] The environmentally friendly knitted fabric has an 8-way coil structure, wherein the 1st and 2nd ways are the bottom layer yarns, the 3rd to 6th ways are the middle layer yarns, and the 7th and 8th ways are the surface layer yarns; the 1st to 8th ways of yarns respectively contain regenerated nylon fibers and regenerated cellulose fibers.

[0026] The knitted fabric provided by the present application has excellent cool feeling, skin-friendliness, good hand feel, and environmental protection properties.

[0027] See also Figure 1 , Figure 1 A schematic diagram of the coil structure of a knitted fabric provided in an embodiment of the present application. Wherein, numbers 1 to 8 represent the number of coil structures respectively. The environmentally friendly knitted fabric described in the embodiment of the present application has an 8-way coil structure, wherein the 1st and 2nd ways are woven to form a bottom yarn structure, the 7th and 8th ways are woven to form a surface yarn structure, and the 3rd to 6th ways form an intermediate layer connecting the bottom yarn and the surface yarn. Some embodiments of the present application interweave a four-layer structure, corresponding to a knitted fabric with a double-layer structure. Generally, the front side of the fabric is woven by the surface yarn (surface yarn), and the back side is woven by the bottom yarn, and the intermediate layer of yarn connects the surface yarn and the bottom yarn. Usually, the back side of the fabric is the side close to the skin of the body. The double-sided structure described in the embodiment of the present application is a coil structure with the same front and back sides.

[0028] In the embodiments of the present application, the bottom yarn is preferably woven from semi-dull regenerated nylon, nylon spandex wrapped yarn and regenerated cellulose fiber. Specifically, the first route contains semi-dull regenerated nylon yarn, regenerated cellulose fiber and spandex, and further, the semi-dull regenerated nylon yarn is 30D / 6F fully stretched yarn; the spandex specification is 30D. Preferably, the second route contains: regenerated cellulose fiber, and 40D / 36F machine-wrapped 600-twist regenerated nylon spandex wrapped yarn. The embodiments of the present application mainly provide double-sided tissue fabrics for ice skin, and there are no special requirements for the elasticity and strength of regenerated cellulose fibers.

[0029] Nylon is the common name for polyamide fiber (PA), and its commercial name is nylon. Among them, nylon 6, nylon 66 and nylon 610 are widely used. The embodiments of this application mainly use nylon 6. Nylon has good mechanical properties and wear resistance. Its aggregated structure is closely related to the stretching and heat treatment of the spinning process. The commonly used fiber cross-section is circular. The official moisture regain of nylon is about 4.5%, which has certain moisture absorption and cooling properties compared to chemical fibers such as polyester. Regenerated nylon is also called nylon recycled material, which is generally produced by melting and granulating nylon yarn, nylon silk or nylon cloth, and can achieve the characteristic quality close to that of new nylon material. The embodiments of this application use semi-dull recycled nylon silk, which can make the surface of the fabric have a comfortable gloss.

[0030] The regenerated cellulose fiber described in the embodiment of the present application is preferably viscose fiber, which is a regenerated cellulose fiber made from natural cellulose as the basic raw material and spun from a cellulose sulfonate solution. Viscose fiber has good hygroscopicity, and the textiles generally made from it have the function of sweat absorption and moisture permeability, and are comfortable to wear. The degree of polymerization of ordinary bonding fibers is 300-400, and the cross-sectional shape is a zigzag skin-core structure. The fineness of common regenerated fibers is 40d, 60d, 75d, etc., and can be composed of 18, 24, 32, 48, etc. monofilaments (the number of roots depends on the number of holes F of the spinneret). Filaments are usually expressed in a fixed length system to indicate the fiber fineness, such as a filament length of 9000 meters and a weight of 1 gram, which is 1 denier (denier is abbreviated as D). Fineness (also known as "denier") is a unit for measuring fabrics and yarns, which refers to the weight of 9000 meters (9 kilometers) of silk / thread at the official moisture regain. In addition, custom weight refers to the length of a certain weight of fiber or yarn. The larger the value, the thinner the yarn. The imperial count is the old national standard unit of measurement for the thickness of cotton yarn. If 1 pound of yarn has 60 840 yards long, the yarn fineness is 60 imperial count, which can be recorded as 60S. The imperial count of a ply is expressed by dividing the imperial count of the single yarn that makes up the ply by the number of plies, such as 60 / 2.

[0031] One of the raw materials of the knitted fabric described in the embodiment of the present application is regenerated cellulose fiber, which is environmentally friendly and renewable, and helps green environmental protection. Preferably, the regenerated cellulose fiber described in the present application is 20D / 144F ultra-fine viscose fiber.

[0032] In the embodiment of the present application, the surface of the bottom yarn and the surface yarn have the same jacquard structure, that is, the front and back sides of the fabric have jacquard structures on the surface, and the texture is the same. The embodiment of the present application uses natural cooling fibers (nylon, viscose fibers) through special weaving methods such as surface jacquard, which can give the fabric a double sense of coolness and skin-friendliness, and has excellent thermal conductivity.

[0033] Spandex is a polyurethane fiber, which is also called elastic fiber because of its excellent elasticity. Spandex yarn is a chemical fiber filament with high elongation at break (more than 400%), low modulus and high elastic recovery rate. It is usually used as a core to make core-spun elastic yarn. The first route described in this application is preferably 30D / 6F semi-dull fully stretched regenerated nylon yarn, 30D spandex and 20D / 144F ultra-fine denier viscose fiber; the preferred embodiment of this application uses ultra-fine denier regenerated cellulose fiber and high-rebound nylon-spun spandex (the effective rebound rate of nylon is about 85%), which has high anti-snagging and anti-pilling properties. In addition, spandex fiber has excellent elastic recovery, which gives the fabric unique stretch recovery.

[0034] In addition to the regenerated cellulose fiber, the second route described in the present application preferably includes 40D / 36F machine-wrapped 600-twist regenerated nylon spandex root-wrapped yarn; the regenerated nylon spandex root-wrapped yarn is an elastic core-wrapped yarn with spandex as the core layer and regenerated nylon filaments as the mechanically wrapped covering layer, which can be referred to as regenerated nylon root-wrapped yarn, and its twisting twist is preferably 600 twists, and the fineness specification is 40D / 36F. The embodiment of the present application preferably uses spandex with good resilience and green and environmentally friendly regenerated nylon root-wrapped twisted yarn. The regenerated nylon root-wrapped twisted yarn has a smooth hand feel, good moisture absorption and permeability, good fabric pilling performance, and also has an elegant luster.

[0035] In the middle layer yarn constituting the knitted fabric in the embodiment of the present application, the third route preferably comprises 30D / 6F semi-dull stretched deformed regenerated nylon yarn plus 30D spandex; the fourth and fifth routes preferably both comprise 40D / 36F machine-wrapped 600-twist regenerated nylon root yarn; the sixth route preferably comprises 80S / 1 regenerated nylon and 30D spandex.

[0036] Among them, semi-dull stretch-deformed regenerated nylon yarn is semi-dull regenerated nylon stretch-deformed yarn (no special requirements for curl). Deformed yarn is a fiber that uses the characteristics of synthetic fiber being plasticized and deformed by heat to make the straight fiber worse and curled under the action of machinery and heat. According to the raw materials and processing technology, it can be divided into conventional deformation yarn (TY), stretch deformation yarn (DTY) and air deformation yarn (ATY). Among them, stretch deformation yarn generally uses pre-oriented yarn (POY) as raw material and is a relatively low-elastic filament made by stretching and deformation in one step. According to the degree of fiber stretching, it can be divided into drawn yarn (DY) and fully drawn yarn (FDY). The fully drawn yarn has relatively stable quality and less hairy yarn and broken ends. In addition, the unstretched and deformed yarn is generally divided into: unstretched yarn (UDY), semi-oriented yarn (MOY), pre-oriented yarn (POY), and highly oriented yarn (HOY) according to the spinning speed, most of which cannot be directly used.

[0037] In addition, the seventh route in the embodiment of the present application preferably includes 80S / 1 regenerated nylon plus 30D spandex; the eighth route preferably includes 40D / 36F machine-wrapped 600-twist regenerated nylon wrapped yarn. Each of the above intermediate and surface yarns contains the regenerated cellulose fiber mentioned above, and preferably, the fineness of the regenerated cellulose fiber is 20 denier / 144f. In the coil structure diagram of the specific embodiment of the present application, the several routes containing spandex all use regenerated nylon spandex wrapped yarn.

[0038] In the embodiment of the present application, the middle layer of the knitted fabric (3rd, 4th, 5th, 6th) is mainly woven from regenerated nylon root yarn; the surface yarn (surface yarn) is woven from regenerated nylon, spandex and regenerated cellulose fiber, and has the same surface jacquard structure as the bottom yarn. The knitted fabric described in the present application has a new and reasonable fabric structure, which can achieve cool breathability, skin-friendly and smooth feel, etc.; its material and processing are environmentally friendly, and it is an environmentally friendly fabric.

[0039] The composition materials of the environmentally friendly knitted fabric described in some embodiments of the present application are: 50wt% recycled nylon, 30-35wt% viscose fiber, 15-20wt% spandex. In a further preferred embodiment, the fabric composition is: 50% recycled nylon, 32% viscose fiber, and 18% spandex. In some embodiments, the weight (unit mass) of the cool and smooth environmentally friendly knitted fabric is 210-220g / m 2 , for example 215g / m 2 The embodiment of the present application has no special restrictions on the color, width, etc. of the fabric, and the fabric can be white, gray, or knitted fabrics of various colors.

[0040] The present application provides a method for preparing the cool, smooth and environmentally friendly knitted fabric as described above, comprising the following steps:

[0041] According to the coil structure of the environmentally friendly knitted fabric, corresponding yarns are selected and interwoven and woven by a knitting machine to obtain fabric grey cloth;

[0042] The fabric grey cloth is sequentially subjected to pretreatment, dyeing and post-finishing to obtain the cool, smooth and environmentally friendly knitted fabric.

[0043] The coil structure, yarn characteristics and selection are consistent with those described above. The present application preferably forms the knitted fabric through a high-needle high-density (such as 40 count) double-layer weaving process to avoid the problem of holes in the fabric due to thin yarns, while giving the fabric a thick and soft feel.

[0044] After obtaining the fabric grey cloth in the embodiment of the present application, it is preferably subjected to open-width water washing, pre-setting, dyeing, water absorption treatment, cleaning, drying, and re-setting in sequence to obtain the environmentally friendly knitted fabric finished product. The open-width water washing and pre-setting are common pre-treatment operations for knitted grey cloth in the art; preferably, the dyeing specifically includes: immersing the pre-treated fabric grey cloth in a dyeing solution containing a leveling agent for dyeing.

[0045] In the specific embodiment of the present application, the dyeing liquid (dye bath) is prepared by dye, dyeing auxiliaries such as leveling agent and water, mainly using active dyes, and the dyeing auxiliaries can be conventional products, such as commercially available anionic leveling agents. The mass volume ratio of the fabric grey cloth to the dyeing liquid is 1g:4~12L; the dyeing temperature, time and other processes are also conventional dyeing processes. After dyeing, conventional water absorption treatment is carried out, hot air drying is carried out after washing, and finally re-setting is carried out to obtain the finished fabric. The principle of the dyeing process includes: the active dye molecules contain active groups, which can react with certain groups on the fiber to form covalent bonds, so the washing and friction fastness are very high. In the immersion dyeing and continuous pad dyeing processes, the fabric is usually treated with a dyeing liquid without an alkali agent first, and then alkali is added to the dyeing liquid or alkali is applied to the fabric to react the dye with the fiber, and finally fully washed with water, soaped, and the floating color is removed. The setting temperature is 145-155℃, and the speed is controlled at 20M-25M / min.

[0046] The knitted fabric obtained in the embodiment of the present application has a reasonable structure and uses cool fibers such as regenerated nylon and regenerated cellulose fibers, which make the fabric have excellent thermal conductivity and a cool and skin-friendly feel. In addition, the knitted fabric prepared in the embodiment of the present application and its production meet green environmental protection requirements. After testing, the contact coolness coefficient / post-wash coolness coefficient of the fabric far exceeds the national standard of 0.2J / cm 2 ·s, greatly improving the cool feeling of the upper body, and multiple washings will not affect the cool feeling, extending the number of uses, and also helping the environment. In addition, the double-layer weaving method of the embodiment of the present application allows the fabric to effectively block ultraviolet rays without any post-processing, and can reach UPF50+.
