Abstract

The invention discloses a three-dimensional jacquard sandwich fabric, which comprises an upper layer structure, a lower layer structure and a middle layer structure. The upper structure and the lower structure are woven from fine denier transparent monofilaments to form a transparent base fabric, and the middle layer structure uses synthetic multifilaments with certain elasticity as the braiding material. Certain patterns are combined to form various patterns, which are exposed on the surface of the fabric through the transparent upper and lower base fabrics, forming a concave-convex jacquard effect on the surface, which can produce a good effect of hollowed-out three-dimensional patterns in the three-dimensional structure. The fabric pattern of the example of the invention has a strong three-dimensional effect, and the hand feeling, comfort and functionality of the fabric are all significantly improved, and it is mainly used in fields such as ladies' bras and shoe materials.

Description

A three-dimensional jacquard sandwich fabric

technical field

The invention relates to the technical field of textile jacquard fabrics, in particular to a three-dimensional jacquard sandwich fabric.

Background technique

The warp-knitted sandwich fabric is a fabric with a three-dimensional structure produced on a double-needle bed Raschel machine. It is mainly connected by an upper structure, a lower structure and an intermediate support line that can maintain the distance between the upper and lower structures. fabric items. Generally, the raw materials of the upper and lower layers are mostly synthetic multifilaments, such as polyester or nylon filaments, and the middle support thread is made of yarns with good toughness and resilience, such as polyester monofilaments. At present, there are mainly three ways to form patterns on such fabrics, as follows:

(a) Form a mesh or two-color effect on the upper or lower structural base fabric by using empty threading, colored yarn and other threading methods;

(b) Using electronic traverse jacquard technology to jacquard the upper or lower structure, and form geometric patterns on the upper and lower base fabrics of the fabric, such as mesh structures of different shapes and sizes;

(c) Using jacquard technology to jacquard the upper or lower fabric to form a jacquard pattern on one side of the fabric.

However, the way of spacer fabric jacquard currently on the market is limited to the jacquard of the upper and lower layers, and only forms patterns on the surface of the fabric, so the three-dimensional effect is not strong. The wet effect is not good, and the traditional sandwich fabric feels relatively stiff, and the softness and comfort in contact with the human body are not good, which affects its practical application in the field of wear such as women's bras.

The connecting yarn uses two or more raw materials of different colors to form Patterns with different color effects; connecting yarns can also be woven with fibers with moisture-wicking and anti-bacterial functions to form a three-dimensional fabric with certain functions, and the fabric feel and moisture-wicking effect are significantly improved.

The pattern pattern formed by the middle layer structure in the three-dimensional jacquard sandwich fabric is formed by pattern design in CAD software, and then the pattern process is introduced into the machine for weaving.

The arrangement density of the intermediate yarns in the pattern area and the transition area of the intermediate layer structure in the three-dimensional jacquard sandwich fabric can be designed in various forms such as full wear, one wear and one empty, two wear and two empty.

The structure of the upper base fabric and the lower base fabric of the three-dimensional jacquard sandwich fabric can be plain fabric formed by warp flat, chain knitting or weft insertion, or mesh fabric formed by empty threading or weave transformation.

The connecting yarns in the three-dimensional jacquard sandwich fabric are selectively woven on the upper base fabric and the lower base fabric, wherein the upper base fabric or the lower base fabric is a convex part in the part with the connecting yarn, and a convex part in the part without the connecting yarn.
