Non-stick warp-knitting elastic fabric

Abstract

A non-stick warp-knitted elastic fabric of a warp-knitted structure, comprising at least a low-fluffiness yarn Y1, a high-fluffiness yarn Y2, and an elastic yarn Y3, wherein the low-fluffiness yarn Y1 and the high-fluffiness yarn Y2 are both located on the surface of the fabric and arranged at intervals of each other; the low-fluffiness yarn Y1, via a bar threaded ai-in, bi-out, forms a low-fluffiness structure, while high-fluffiness yarn Y2, via another bar, threaded mj-out, nj-in, forms a high-fluffiness structure; the elastic yarn Y3 forms an elastic structure; and both the low-fluffiness yarn Y1 and the high-fluffiness yarn Y2 form raised areas on the skin-facing surface of the fabric. According to the present application, the fabric of the above structure not only does not stick to the body, but also has properties of good air permeability, quick moisture absorption and drying, and less prone to curling.

1 . A non-stick warp-knitted elastic fabric, comprising at least a low-fluffiness yarn Y 1 , a high-fluffiness yarn Y 2  and an elastic yarn Y 3 , (at least have 3 yarns where Y 2  has higher fluffiness than Y 1  and Y 3  is an elastic yarn) warp knitted to form the fabric via separate guide bars with a lapping plan so that yarn Y 1  and yarn Y 2  can both located on a surface of the fabric and arranged at intervals of each other; wherein
 yarn Y 1  constitutes a structure of low fluffiness, knitted using a bar threaded using a i b i  as a base threading unit, wherein 1≤a i ≤50, 1≤b i ≤50, Where a i  is the number of guide needles in a guide bar threading yarns in (and b i  is the number of guide needles in a guide bar not threading yarns in; the base threading unit a i b i  further forms a repeating unit which comprises at least one (1) base threading unit but no more than ten (10) different base threading units and the repeating unit will be repeated till full fabric width; 
 yarn Y 2  constitutes a structure of high fluffiness, knitted using a bar threaded using m i n j  as a base threading unit, wherein 1≤m j ≤50, 1≤n j ≤50; Where m j  is the number of guide needles in a guide bar threading yarns in and n j  is the number of guide needles in a guide bar not threading yarns in; the base threading unit m i n j  further forms a repeating unit which comprises at least one (1) base threading unit but no more than ten (10) different base threading units and the repeating unit will be repeated till full fabric width; 
 yarn Y 3  forms an elastic structure, knitted using a guide bar fully threaded to full fabric width; and 
 both yarn Y 1  and yarn Y 2  formed raised areas on the next to skin surface of the fabric.
