Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of knitted fabrics, in particular to a double-sided weft knitted fabric with moisture absorption and heat generation functions, which is suitable for knitted clothing fabrics worn close to the body in autumn and winter. Background Art
[0002] Warm knitted clothing is widely used for knitted underwear and other close-fitting wear in autumn and winter. Passive thermal clothing generally prevents heat loss inside the clothing by controlling the thermal convection, radiation, and conduction of the fabric. However, this passive thermal insulation is related to the thickness and tightness of the fabric, the material and thickness of the thermal insulation layer, and the material and thickness of the heat insulation layer. Therefore, the fabric is thick and the clothing is bloated, which not only affects the appearance of wearing, but also affects human activities. If the external heating element is introduced, the active thermal insulation material that generates heat for warmth autonomously will actively generate heat, the temperature will rise, the heat will be uniform, the heating rate will be fast, the warmth effect will be good, and the comfort performance will be good. Therefore, it is a hot spot for the research and development of light and thin clothing fabrics in autumn and winter.
[0003] Hygroscopic and heat-generating fibers are a type of temperature-regulating material that absorbs water molecules moving in the human body-clothing microclimate to obtain some heat energy through moisture absorption, and have broad application prospects in the textile field. Common hygroscopic and heat-generating fibers in the market include sub-acrylate fibers, modified polyacrylic fibers, ultra-fine denier acrylic fibers, modified acrylic fibers, modified viscose, etc. However, due to the high price of hygroscopic and heat-generating fibers, through the design of knitting structure, the design of fabric structure parameters, and the reasonable configuration of blended yarns of hygroscopic and heat-generating fibers and other fibers, knitted fabrics with light weight per square meter and excellent hygroscopic and heat-generating functions are developed, which have good market application prospects. Utility Model Content
[0004] In order to further improve the thin and light fabrics with good moisture absorption and heat generation functions, the utility model provides a double-sided weft knitted fabric with moisture absorption and heat generation functions, characterized in that: the double-sided weft knitted fabric consists of an outer layer 1, an inner layer 2, and a micro-raised layer 3 of the inner layer, the outer layer 1 and the inner layer 2 both appear to be a front coil loop structure, woven with a 1+1 double rib structure, and the micro-raised layer 3 is prepared by brushing the inner layer.
[0005] The double-sided weft-knitted fabric with moisture absorption and heat generation function is characterized in that: the double-sided weft-knitted fabric is preferably a blended yarn prepared by modified acrylic fiber with moisture absorption and heat generation function and cellulose fiber through a siro compact spinning process, the modified acrylic fiber is preferably EKS fiber, the cellulose fiber is preferably modal fiber and cotton fiber, the blended yarn is preferably EKS, modal and cotton, the mass blending ratio is 15:55:30, and the preferred yarn fineness is 32S.
[0006] The double-sided weft knitted fabric with moisture absorption and heat generation function is characterized in that the blended yarn preferably has a yarn twist of 890 to 900 twists / m and a yarn twist coefficient of 340 to 350.
[0007] The double-sided weft knitted fabric with moisture absorption and heat generation function is characterized in that: the preferred fabric weight per square meter is 240 g / m 2 .
[0008] Compared with the prior art, the double-sided weft knitted fabric with moisture absorption and heat generation function provided by the utility model has the following characteristics:
[0009] (1) Lightweight and has good moisture absorption and heat generation function: Modified acrylic fiber EKS with good moisture absorption and heat generation function is preferred, and it is blended with cellulose fiber modal and cotton with high moisture regain. The proportion of EKS fiber is controlled to 15%, which can make the fabric have good moisture absorption and heat generation function. Weft knitted double rib fabric is preferred, and the weight per square meter is controlled to be 240g / m 2 , the fabric is overall light and thin.
[0010] (2) Soft touch and warming effect: The inner layer of the double rib fabric is lightly raised and finished, giving it a fine velvet feel. This not only effectively improves the softness of the touch, but the fine velvet can also store still air, effectively increasing the sense of warmth without increasing the mass of the fabric too much.
