Example Embodiment

[0036] Example 1

[0037] Use 90dtex-36f-flat cross-section hollow cationic dyeable polyester false twist yarn and 33dtex spandex to knit on a 24G 33 inch double-sided circular knitting machine. The structure is double-sided ribbed air layer structure, and the weight is 186g / m. 2 , The grey cloth with a width of 186m, and then undergo pre-shaping-scouring-overflow dyeing-finishing processing (including sanding processing) to obtain a weight of 168g / m 2 The performance parameters of the obtained fabric are shown in Table 1, and the light weight rate = (the gram weight of the fabric in Comparative Example 1-the gram weight of the fabric in Example 1) / the gram weight of the fabric in Example 1 * 100%.

[0038] Predetermined condition: 190℃*90 seconds, scouring condition: scouring agent 2g / l, 95℃*20min, overflow dyeing condition: cationic dye 6%owf, 120℃*60min, finishing condition: soft resin 2g / 1. Water-absorbent resin 4g / l, 130℃*90 seconds.

Abstract

The invention discloses a fabric containing hollow fiber and a production method thereof. The fabric containing hollow fiber is a knitted fabric formed by at least hollow cation dyeable false twisted yarn or staple fiber yarn and spandex fiber. Tested according to the JISL1096:2010 standard, the fabric obtains a filling power more than 4.0 cm3/g and a gram weight higher than 150-250 g/m2; the hollow area of more than 80% of the filaments of the hollow cation dyeable false twisted yarn or staple fiber yarn is 50-150 mm2. Knitted from the hollow cation dyeable false twisted yarn or staple fiber yarn with restorable degree of hollowness, the fabric containing the hollow fiber ensures the elasticity, light weight and soft hand feeling.

Description

technical field [0001] The invention relates to a textile, in particular to a hollow fiber-containing fabric with a lightweight, fluffy and warm-keeping function. Background technique [0002] In a modern society where living standards are improving day by day, people's requirements for clothing, especially winter clothing, are no longer at the stage of keeping warm from the cold, and they are more required to have both thermal insulation and light weight. Among them, polar fleece and brushed wool products are deeply loved by consumers for their unique feel and warmth retention. [0003] In the past, the raised fabrics were generally polyester or cotton-polyester interwoven raised fabrics, which were much heavier than ordinary fabrics and had a bad hand feeling; when spandex and spandex composite yarns were interwoven with polyester or cotton-polyester, the thickness The weight will be greater, the cost is also very expensive, and the sense of thickness is too obvious, and ...
