Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 1 to 3. Ultralight thin stiff and smooth and soft knitting sandwich fabric, including the surface fabric body, the surface fabric body includes the upper strata, lower floor and articulamentum, the articulamentum is located between upper strata and the lower floor, upper strata and lower floor pass through the articulamentum and connect, the arrangement that 2 way 2 needles were all adopted to upper strata and lower floor, the articulamentum adopts 2 way 1 to contain the arrangement that 1 was put down to arrange, the raw materials that the upper strata adopted are 40D/12F semi-gloss dacron FDY (FULLY DRAWN YARN, the FULLY drawn Yarn) the face Yarn and the backing Yarn of 20D spandex, the raw materials that the lower floor adopted are 50D/72F low-elasticity semi-gloss dacron DTY (Draw textile Yarn, Draw textured Yarn) the base Yarn and the backing Yarn of 20D spandex, the raw materials that the articulamentum adopted is 30D/1F connection Yarn. Because the veil adopted by the upper layer is 40D/12F semi-gloss polyester FDY, is non-superfine fiber with the F/D less than 1, and is FDY filament, and the stiffness of the cloth surface can be kept by matching with the weaving process of the fabric; the bottom yarn of the lower layer is made of 50D/72F low-elasticity semi-gloss polyester DTY (draw textured yarn), the F/D of the DTY is more than 1, and the softness and comfort of the skin-attached surface of the fabric can be ensured by matching with the weaving process of the fabric; the connecting yarns 3 ensure the thickness and the stiffness of the cloth surface and also ensure that the cloth surface does not prick.

According to the ultra-light thin stiff and soft knitted sandwich fabric, the upper layer is connected with the lower layer through the connecting layer, the connecting layer is alternately arranged between the coils of the upper layer and the lower layer at intervals by adopting the arrangement mode to play a connecting role, and the connecting layer enables the fabric surface to be stiff and smooth and to have a certain thickness; meanwhile, the upper layer and the lower layer adopt the arrangement mode to form a plain weave structure, so that the fabric surface is fine and smooth and comfortable; by combining the raw material selection of the corresponding upper layer and the lower layer, the fabric body has the characteristics of good four-side elasticity, super lightness and thinness, good moisture absorption and air permeability, stiffness and softness and wearing comfort.

The needle arrangement mode of the fabric body during weaving is as follows: the upper disc needles 12/2 needles in total are in one cycle, and the lower disc needles 21/2 needles in total are in one cycle (as shown in figure 2), and the triangular arrangement mode is as follows: one cycle for 6 passes (as shown in figure 1). Therefore, the upper layer and the lower layer can be conveniently connected with the connecting layer, and the production and weaving are convenient; meanwhile, the upper layer and the lower layer are 2-path 2-needle fully-arranged plain layers which are respectively formed into a ring on the upper disc and a ring on the lower disc of the circular knitting machine to form an outer surface and a skin-attached surface, and the connecting layers are respectively alternately arranged between the coils of the upper layer and the lower layer in a penetrating manner at intervals and are connected with the upper layer and the lower layer in a tucking manner.

The doffing mode of the fabric body is as follows: 1F and 4F fall 30D/1F connecting yarns, 2F and 5F fall 40D/12F semi-gloss polyester FDY face yarns and 20D spandex lining yarns, and 3F and 6F fall 50D/72F low-elasticity semi-gloss polyester DTY bottom yarns and 20D spandex lining yarns. Therefore, the softness and comfort of the skin-contacting surface of the fabric body are ensured; the connecting yarns ensure the thickness and the stiffness of the cloth surface and also ensure that the cloth surface is not stabbing.

The yarn feeding amount of the fabric body adopts 100 needles: the lengths of the 1F and 4F connecting yarns are 380mm, the lengths of the 2F and 5F surface yarns and the backing yarns are 250mm and 90mm respectively, and the lengths of the 3F and 6F bottom yarns and the backing yarns are 250mm and 90mm respectively. Therefore, the yarn feeding amount can enable the transverse elasticity of the fabric body to reach more than 150%, the longitudinal elasticity to reach more than 80%, and the four-side elasticity and the comfort of the fabric are further guaranteed.
