Preparation method of colored space-dyed loop yarn double-faced woolen cloth and prism vision detection device

Abstract

The invention discloses a preparation method of colored space-dyed loop yarn double-faced woolen cloth. The preparation method comprises the following steps: preparing loop yarn, and weaving by adopting twill weave. The preparation of the loop yarn comprises the following steps: spinning nylon yarn into nylon mink wool yarn, performing space dyeing treatment on the nylon mink wool yarn, and spinning the space-dyed nylon mink wool yarn and polyester yarn into the loop yarn. The invention further discloses a prism vision detection device for the double-faced woolen cloth. The prism vision detection device comprises two right-angled prisms which are arranged up and down, wherein a to-be-detected material is placed between the two right-angled prisms, a camera is arranged in the direction right facing the side face of the material, a material mirror image plate is arranged on a vertical face right facing the bevel edges of the right-angled prisms, and a lens of the camera is rotatable. According to the preparation method, manual vision detection is not needed, the number of cameras is small, the number of detection faces is large, the camera does not need to move, detection personnel do not need to change positions back and forth for detection, and labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to a preparation method of double-faced cloth of colored segment dyed loop yarn. Background technique [0002] Due to the progress of the times, people's living standards continue to improve, and then the requirements for clothing are further improved, and people's selection level for the pattern of fabrics is also increasing. Double-faced woolen is a piece of fabric woven from two fabrics with different textures. The double-faced woolen fabric has a delicate hand feel, tight texture, crisp and elastic, and is suitable for different age groups. Existing double-faced fabrics are generally made of woolen jacquard, and jacquard is usually produced by jacquard machines, and the price of jacquard machines is relatively expensive, which is too high for small and medium-sized enterprises. For the inspection of double-faced fabrics, some use manual work, and some use machines. However, for materials with many types of defects and many co...
