[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] Embodiment 1
[0020] Combination Figure 1-4The present embodiment is described in detail. A breathable and warm polyester-viscose blended knitted sweater comprises: a knitted sweater body, the knitted sweater body comprises a body 1 and sleeves 2; the body 1 and sleeves 2 are connected by sewing; the body 1 and sleeves 2 are breathable and warm fabrics; the breathable and warm fabrics comprise a first fabric layer 3 and a second fabric layer 4 which are compounded; the first fabric layer 3 and the second fabric layer 4 are compounded by array-distributed dot hot melt adhesive; the first fabric layer 3 is woven by a composite yarn; the composite yarn is twisted by polyester-viscose blended yarn and warm yarn; the second fabric layer 4 is woven by two combs GB1 and GB2; the inlay yarn numbers of GB1 and GB2 are as follows:
[0021] GB1: 2-1-1 / 1-0-1 / / , 1 empty and 1 penetration;
[0022] GB2: 2-3-2 / 1-0-1 / / , 1 penetrate and 1 empty.
[0023] The second fabric layer 4 is a warp knitted terry fabric, which has a full hand feel, good elasticity, good warmth retention, a stable terry structure, and good wearing performance. GB1 is a terry comb bar, GB2 is a ground yarn comb bar, and the base fabric is formed on alternate needles. The terry comb bar intermittently forms loops on adjacent needles, and terry loops are formed after the loops are removed.
[0024] Further, the warm yarn is combed long-staple cotton superfine acrylic EKS siro-spun knitting yarn. The combed long-staple cotton superfine acrylic EKS siro-spun knitting yarn is known, with a blending ratio of combed long-staple cotton / superfine acrylic / eks 40 / 35 / 25 and a fineness of 14.6 tex. Long-staple cotton fiber has good length, high strength, good consistency of fineness, good hygroscopicity, and its fabric is delicate, soft and comfortable to the touch, with a silky luster; ultrafine acrylic fiber is soft, fluffy, strong, and has good hygroscopicity. Its fabric has the natural feel of silk, is thin and soft, has good hygroscopicity and breathability, and has irreplaceable excellent characteristics such as warmth retention, mildew resistance, insect-free, light weight, and waterproof; EKS fiber is a synthetic fiber "olefin fiber", which can not only regulate the temperature and humidity between the human body and clothes, but also protect the human body and the environment. Wearing EKS fiber products in the cold winter is conducive to its function of absorbing sweat and generating heat absorption, which increases the temperature between the human body and the clothes, making people feel warm and comfortable. The blending of combed long-staple cotton with ultrafine acrylic and EKS fibers to produce siro spinning knitting yarn combines the advantages of the three fibers and provides a new warm yarn.
[0025] Furthermore, the GB1 is penetrated with ultra-fine shaped acrylic fiber yarn. The cross section of the ultra-fine shaped acrylic fiber is dumbbell-shaped. This structure makes it difficult for single fibers to be tightly gathered, increases the static air between the fibers, and under the same quality, the thermal insulation performance is 20% higher than that of wool, with good softness, lightness, and warmth retention characteristics.
[0026] Furthermore, Outlast acrylic air conditioning fiber yarn is inserted into GB2. The Outlast acrylic air conditioning fiber is a phase change temperature regulating fiber, which is made by encapsulating thermosensitive phase change materials in microcapsules and implanting them into acrylic fibers. Through the solid-liquid conversion of the phase change material, the effect of heat absorption and heat release is achieved, and two-way temperature regulation is realized, so that the human body is kept in a comfortable microclimate as much as possible.
[0027] Embodiment 2
[0028] The difference from the first embodiment is that the warm yarn is a heat-generating acrylic fiber and cuprammonia fiber blended yarn. The heat-generating acrylic fiber and cuprammonia fiber blended yarn is known and is blended from 60% of ultra-fine anti-pilling heat-generating acrylic fiber and 40% of cuprammonia fiber. Compared with ordinary fibers, the ultra-fine denier anti-pilling heat-generating acrylic fiber has four special functions: moisture absorption and heat-generating function, which refers to mixing special moisture absorption and heat-generating materials into the spinning solution of chemical fibers. These heat-generating materials can absorb part of the external moisture and convert it into heat; warm-keeping function, which can effectively prevent the loss of heat and the invasion of cold air from the outside; moisture permeability function, when the body produces sweat, the moisture absorption and heat-generating fiber can quickly absorb the moisture produced by the body and transfer it to the surface of the fabric to keep the body dry. The moisture permeability function is achieved by changing the cross-sectional shape of the fiber. The cross-section of the heat-generating acrylic fiber is an irregular polygon, and the fiber surface has micropores and grooves. The micropores make the fiber have a good wicking function, and the surface grooves facilitate the transfer of moisture absorbed by the fiber to the outer layer of the fabric; it is not easy to pilling. Ordinary acrylic fibers are easy to pilling, which affects the appearance and service life of the fabric. Hygroscopic heat-generating acrylic is an ultra-fine denier fiber with an irregular polygon cross-section and a rough fiber surface. After being spun into yarn, the fiber cohesion is large and it is not easy to pilling. Cuprammonia fiber is a cellulose fiber made from cottonseed linter in cotton. It has good moisture absorption, softness and skin-friendliness. When blended with ultra-fine denier anti-pilling acrylic fiber, the woven fabric can have both warmth retention and comfort performance.
[0029] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
