Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a highly elastic double-sided fabric for autumn and winter knitted underwear. Background Art

[0002] In the prior art, single-sided knitted fabrics form loops together with spandex, showing high elasticity in both longitudinal and transverse directions. However, the elastic elongation of double-sided knitted fabrics for autumn and winter knitted underwear is restricted by the intermediate connecting layer. With the further pursuit of wearing comfort by people and the development of elastic knitting technology, elastic spandex is increasingly introduced into the knitted underwear fabric and interwoven with the main yarn, adding elastic comfort to the underwear fabric and making the autumn and winter underwear fit well and have better warmth retention. However, there are many deficiencies in the improvement of the elasticity of autumn and winter double-sided knitted underwear fabrics.

[0003] For example, Chinese Patent Publication No. CN 218026592 U consists of an outer layer, an inner layer and connecting lines between the two layers. The outer layer and the inner layer adopt elastic layers formed by the main yarn and spandex interweaving in loops together. Its main feature is that spandex yarn is used as the connecting line, enabling the elastic outer layer and the elastic inner layer to fully stretch elastically in the transverse and longitudinal directions without being affected by the connecting line, ensuring the high elasticity of the double-sided fabric. At the same time, both sides of the fabric are surface fluffed. Although this technical solution makes the double-sided fabric highly elastic, due to the elastic tightening effect of the connecting spandex, an intermediate air layer cannot be formed, lacking the warmth retention effect of the air layer utilized by the double-sided fabric of autumn and winter knitted underwear. In addition, although both sides are fluffed, the main yarns on both sides are woven with spandex together. To avoid breaking the spandex during fluffing, only slight fluffing can be done, which only improves the hand feeling and has a very limited improvement on the warmth retention effect. Therefore, there is an urgent need in the current market for a knitted fabric that has high elasticity in both longitudinal and transverse directions, also has the warmth retention effect of an air layer, can pull out longer fluff on one side of the fabric to increase the warmth retention of the highly elastic knitted fabric, and uses different functional raw materials on both sides of the fabric to meet the multiple wearing performance requirements of autumn and winter knitted underwear. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a highly elastic double-sided fabric for autumn and winter knitted underwear in view of the deficiencies in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A highly elastic double-sided fabric for autumn and winter knitted underwear, comprising: an inner layer, an air layer, and an outer layer; wherein,

[0007] The inner layer is composed of a first plain stitch structure, and the first plain stitch structure includes: a plurality of first coil rows arranged longitudinally, and the first coil row includes: a plurality of first functional yarns and spandex filaments co-woven first coils;

[0008] The outer layer is composed of a second plain stitch structure, and the second plain stitch structure includes: a plurality of second coil rows arranged longitudinally, and the second coil rows include: second coils woven from a plurality of second functional yarns;

[0009] A plurality of connecting lines are made of spandex filaments and alternately pass through the first coils and the second coils to form an air layer between the inner layer and the outer layer;

[0010] Among them, the connecting lines make connections between the first coil rows and the second coil rows every three to four coil rows longitudinally. The longitudinal arrangement numbers of the first coil rows where the same connecting line passes through and the second coil rows where the second coils it passes through are the same; the adjacent first coils passed through by the same connecting line are separated by one first coil; the adjacent second coils passed through by the same connecting line are separated by one second coil.

[0011] Preferably, the first functional yarn is composed of filament or staple fiber yarn, and the second functional yarn is composed of filament or staple fiber yarn.

[0012] Preferably, it further includes: a flocking layer provided on the outer surface of the outer layer.

[0013] Preferably, the length ratio of the first coil to the second coil is 1:(1.1 - 1.2).

[0015] The present utility model provides a stretch double-sided knitted fabric, especially a double-sided knitted fabric with intermediate connecting lines, high elasticity in both longitudinal and transverse directions, an air layer and surface flocking. The spandex is connected on both sides of the spaced rows, avoiding the restraint of the conventional raw material connection on the elastic elongation, enabling the double-sided knitted fabric to have high elasticity in both longitudinal and transverse directions. While having high elasticity in both longitudinal and transverse directions, it also has a warm air layer, increasing the warmth retention of the high-elastic knitted fabric. While having high elasticity in both longitudinal and transverse directions, the side of the fabric that is not co-woven with the spandex can also pull out longer fluff, increasing the warmth retention of the high-elastic knitted fabric. Different functional raw materials are used on both sides of the fabric to meet the needs of improving the multiple wearing performances of autumn and winter knitted underwear.

[0026] Among them, the first functional yarn is composed of filament or staple fiber yarn, and the second functional yarn is composed of filament or staple fiber yarn;

[0027] Among them, the connecting line is knitted by spandex;

[0028] Among them, a plurality of connecting lines 4 alternately pass through the first coils and the second coils to form the air layer 2 between the inner layer 1 and the outer layer 3;

[0029] Among them, the connecting line 4 makes a connection between the first coil row and the second coil row every three to four coil rows longitudinally, and the longitudinal arrangement number of the first coil row where the first coil passed through by the same connecting line 4 is the same as that of the second coil row where the second coil passed through; there is an interval of one first coil between adjacent first coils passed through by the same connecting line 4; there is an interval of one second coil between adjacent second coils passed through by the same connecting line 4;

[0030] Specifically, the "longitudinal arrangement number" is the value obtained by sequentially arranging the first (second) coil rows longitudinally in the first (second) plain stitch structure and then counting them in order.

[0031] For example: The first connecting line (4) sequentially passes through the first first coil of the first row of the first coil row, the second second coil of the second row of the first coil row, the third first coil of the first row of the first coil row, the fourth second coil of the second row of the first coil row... The second connecting line (4) sequentially passes through the first first coil of the fourth row of the first coil row, the second second coil of the fourth row of the second coil row, the third first coil of the fourth row of the first coil row, the fourth second coil of the fourth row of the second coil row...
