Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of textile functional fabric, specifically relates to a kind of free stretchable and anti-falling apart lace fabric. BACKGROUND

[0002] It is known that lace fabric is more and more widely used in application due to its gorgeous pattern appearance and openwork design style, and is also recognized by most users. However, the existing products are one-sidedly pursuing delicate appearance and ignoring the inevitable hand feeling and stretchability in actual use, and the products with good hand feeling and excellent stretchability will have more space in the use of garments.

[0003] In addition, industry technical personnel also know that the weaving capacity of lace fabric is always lower than that of ordinary non-lace or jacquard warp-knitted fabric, and in some cases, the difference is relatively large. Low capacity directly affects production efficiency and also indirectly affects product price and market competition. Therefore, improving the weaving capacity of lace fabric is also a problem that fabric manufacturers need to face.

[0004] CN 102560866 A discloses a soft and comfortable underwear lace fabric with good stretchability, which comprises a fabric main body composed of warp yarn and weft yarn, characterized in that the content percentage of warp yarn and weft yarn raw materials of the fabric main body is: 23.8% of nylon 100D, 6.1% of nylon 140D, 14.3% of nylon 210D and 55.8% of nylon 40D. The fabric main body is knitted by a warp knitting machine using two groups of ground yarn and two sets of positive warp feeding system, and the dyeing and finishing process is oil removal dyeing one-bath method---130℃ setting. The technical index of the example is that the elastic elongation rate in warp direction reaches 89%, and the elastic elongation rate in weft direction reaches 128%.

[0006] The on-machine density CPC of the fabric in the traditional after-finishing process is usually between 16-30 when weaving, and the length of loop column and extension line of the formed loop is relatively short, and the loop is relatively dense.

[0007] The above two patents emphasize good stretching performance, but the actual test value is not outstanding, and the use of such fabric on some garments with strict requirements on opening will affect the wearing experience of the user. SUMMARY
