Provided are a filling body and the use thereof. The filling body comprises a surface fabric, a lining fabric and a filling material between the surface fabric and the lining fabric, wherein the ventilation capacity of the lining fabric is between 10.0 cm 3 /cm 2 /s and 200 cm 3 /cm 2 /s, and the filling material is a continuous fibre filling cotton with a core-sheath structure, wherein same at least comprises dacron continuous fibres. The filling body has the characteristics of a light weight, heat preservation and breathability, and also has an enhanced laundering durability and motion followability, while maintaining the original comfort.
A: A structure preventing down feather displacement and penetration and maintaining fabric elasticity and a manufacturing process therefor. The structure comprises two fabric layers (1) and down feathers (2), wherein the down feathers (2) are filled into the space between the two fabric layers (1); the structure further comprises multiple connection points (3); the connection points (3) are used for positioning the down feathers (2) and distributing the down feathers (2) in a netted mode; the two fabric layers (1) both are an extended, elastic fabric, and the down feathers (2) are wrapped with elastic air-permeable films (4). The structure enables the fabric elasticity of elastic down feather products to be maintained to the maximum extent, enables the distribution of down feathers to be always kept even and prevents down feather penetration.
B: A down fabric, comprising an inner fabric, an outer fabric, and an adhesive layer; the inner fabric comprises a first down cladding layer (1) and a basal body silky layer (2); the outer fabric comprises a second down cladding layer (3) and a windproof layer (4); sealed down bulges (5) are regularly arranged between the first down cladding layer (1) and the second down cladding layer (3); the cross section of the down bulges (5) is honeycomb-shaped; the down bulges (5) are filled with down; and the intersections of adjacent down bulges (5) are respectively adhered to the first down cladding layer and the second down cladding layer by means of the adhesive layer. Because the down bulges are filled with down, and the cross section of the down bulges is honeycomb-shaped, seamless connection is achieved among adjacent down bulges (5), avoiding poor thermal insulation performance caused by too large down intervals; moreover, the intersections of adjacent down bulges (5) are respectively adhered to the inner fabric and the outer fabric by means of the adhesive layer, to avoid the problem of down drilling-out caused by thread connection.
C: A filling object. The filling object is provided with covering cloth (1), lining cloth (2) and a filling material. The filling material is made of long fiber cotton (3). The filling material and the lining cloth (2) are integrally formed, and the covering cloth (1) and the lining cloth (2) are integrally formed. The covering cloth (1) and the filling material are indirectly connected by means of the lining cloth (2). The filling object can improve performance of resisting again down leakage, and alleviate the problems of deviation and caking of the filling material after being washing. In addition, the fluffy performance of the filling material is good, the filling material has the feature of having a light weight and keeping warm, and provides the style of softness and smoothness for hand feeling, and has good performance of sustaining machine washing, and can be used to replace eiderdown filling products.
D: A double-sided knitted fabric comprises a surface layer (1) and an inner layer (2), which are connected in a looping manner. The inner layer (2) has a concavo-convex structure, and at least one of the longitudinal and lateral directions of each convex portion unit (3) is composed of 3 to 10 loops. The skin-contact surface of the double-sided knitted fabric has excellent dry performance, has a good comfort level for wearing, especially is suitable for production of T-shirts, POLO shirts and the like.
