Problems solved by technology

However, these methods can only satisfy part of the functionality, or can only achieve a certain thermal insulation effect indoors, and once there is wind, the thermal insulation is almost lost, or the manufacturing method is too complicated, the effect is poor, and the cost is too high

Embodiment 1

[0036] The fabric warp is made of 50D polyester low-elastic network yarn and 40D polyester hollow low-elastic network filament, and the weft is made of 50D polyester low-elastic network yarn. The ratio of surface warp to inner warp is 2:1. The front side is a plain weave, and the back weft uses a hollow yarn with a hollow rate of 30%. After warping, sizing and other preparation processes, the yarn is woven into gray cloth through double weaving, and the gray cloth is made into fabric through refining, drying, heat setting, dyeing, resin, finishing and heat setting. The grammage of gained fabric is 114g / m 2 , the surface density is 140×92 pieces / inch, the thermal insulation Cro value is 0.66, and the average apparent specific gravity is 1.181g / cm 3 , the cover factor of the surface side is 2120, and the air passage is 4.5cc / cm 2 · sec, the mass percentage of the hollow yarn in the fabric is 48%; compared with the ordinary polyester fabric of the same gauge (comparative exampl...

Embodiment 2

[0038] The warp of the fabric is made of 50D polyester low-elastic network yarn, the weft yarn is a combination of 50D polyester low-elastic network yarn and 40D polyester hollow low-elastic network filament, and the ratio of surface weft to inner weft is 1:1. The front side is a plain weave, and the weft yarn on the back side uses a hollow yarn with a hollow rate of 30%. The yarn is warped, sizing and other preparatory processes, and weaved into gray cloth with double weft weaving. The gray cloth is made into a fabric through the processes of refining, drying, heat setting, dyeing, resin, finishing and heat setting. The grammage of gained fabric is 100g / m 2 , the surface density is 160×85 / inch, the thermal insulation Cro value is 0.65, and the average apparent specific gravity is 1.19g / cm 3 , the cover factor of the surface side is 2080, and the air passage is 4.2cc / cm 2 · sec, the hollow yarn accounts for 45% of the mass percentage of the fabric. Compared with the ordina...

Embodiment 3

[0040] The warp yarn of the fabric adopts 75D low-elastic network polyester filament, the weft yarn adopts a combination of 75D polyester low-elastic network filament and 75D polyester hollow low-elastic network yarn, and the hollow rate of the 75D hollow yarn is 50%. The surface side is plain weave, the inside side is twill weave, and the ratio of surface weft to inner weft is 1:1. The yarn goes through preparation processes such as warping and sizing, and finally it is made into gray cloth with a two-layer weave. The gray cloth is made into a fabric through the processes of desizing, drying, heat setting, dyeing, resin, finishing and heat setting. The grammage of gained fabric is 267g / m 2 , the surface density is 150×87 pieces / inch, the thermal insulation Cro value is 0.68, and the average apparent specific gravity is 1.04g / cm 3 , the cover factor of the surface side is 3080, and the air passage is 3.0cc / cm 2 · sec, hollow yarn accounted for 50% of the mass of the fabric....

Abstract

The invention aims to provide a lightweight heat-preservation fabric. The ordinary fiber yarn and at least one hollow polyester fiber yarn with the hollow rate of 10-80% are texturized, arranged and woven into a two or three-layer gray fabric with the hollow polyester fiber yarn arranged in the inner layer by simulating the heat-preservation theory of a thermos bottle, and then the gray fabric is subjected to desizing, dyeing and other processes to finally become the lightweight heat-preservation fabric with the hollow yarn coverage rate of 70-100%. The final product has the lightweight rate of 10-50% and the heat-preservation magnification of 1.1-1.5. The lightweight heat-preservation fabric has the characteristics of simple process and low cost.

Description

technical field [0001] The invention relates to a light-weight thermal insulation fabric. Background technique [0002] With the improvement of living standards, people's requirements for clothing are also getting higher and higher. No longer staying at the stage of covering the body to keep out the cold, but also more demanding its functionality and comfort while pursuing aesthetics. For example, you want to wear cool and comfortable clothing when it is hot, and you want to wear warm and lightweight clothing when it is cold. Products currently on the market are mainly made of cotton blended yarns and other yarns with low thermal conductivity, or some far-infrared finishing agents are used to achieve the effect of heat preservation. As disclosed in patent CN200810018550, there is a light-weight heat-retaining fabric and its manufacturing method, which simply introduces low-apparent-density yarns during fabric design to achieve the purpose of light-weight heat preservation....
