Description

Technical Field

[0001] The invention relates to the field of circular knitting machines, in particular to a double-sided non-falling pile automatic cutting pile circular knitting machine and a knitting process. Background Art

[0002] The double-sided non-pile knitting process of the circular knitting machine refers to the process of connecting the veil knitted by the upper needle disc needles with the veil knitted by the lower needle disc needles through connecting yarns, so that the veil knitted by the upper and lower needle disc needles fit each other to achieve the integration of the front and back sides.

[0003] At present, the main types of machines for producing weft knitted fleece fabrics are: ordinary double-sided machines, front and back terry machines, and cut loop terry machines. First of all, the fleece fabrics produced by ordinary double-sided machines are processed in the later stage, and the fleece is formed by grabbing the surface of the double-sided non-pile knitted fabric. This kind of fleece is produced by destroying the fabric coils, making the fabric structure unstable. Some products are prone to hair loss, and only very short fleece can be formed on the surface of the knitted fabric, and the softness of the fleece is poor; while the fabrics produced by the front and back terry machines and the cut loop terry machines are single-sided fabrics, and the fleece coils themselves are part of the veil. The fleece length of the knitted fabrics produced by the front and back terry machines is limited, while the fleece coils of the knitted fabrics produced by the cut loop terry machines are long, but the fleece coils themselves are veil coils, making the surface of the fabric veil rough and easy to pilling. All of them must be processed by the later composite pasting process before they can be used.

[0004] To sum up, a double-sided non-falling pile automatic cut pile knitting circular machine and weaving process have been developed. Through its unique weaving process, the fabrics produced by it do not need to go through complicated post-processing processes to obtain environmentally friendly, soft and comfortable knitted fabrics, which greatly saves production costs. This is urgently needed by relevant textile fabric companies and is in line with the environmental protection requirements advocated by the country. Summary of the invention

DETAILED DESCRIPTION

[0060] In order to make the embodiments of the present invention, all belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0061] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as referring to the purpose, technical solutions and advantages of the methods. To be more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0062] At present, the plush fabrics produced by ordinary double-sided machines are processed in the later stage, and the fluff is formed by the surface of the double-sided knitted fabric through the plucking treatment. This kind of fluff is produced by destroying the fabric coils, which makes the fabric structure unstable. Some products are prone to hair loss, and only very short fluff can be formed on the surface of the knitted fabric, and the softness of the fluff is poor; while the fabrics produced by the front and back terry machines and the cut loop terry machines are single-sided fabrics in nature, and the plush coils themselves are components of the veil. The length of the plush of the knitted fabrics produced by the front and back terry machines is limited, and the knitted fabrics produced by the cut loop terry machines have long fluff coils, but the fluff coils themselves are veil coils, which makes the surface of the fabric veil rough and easy to pilling. The whole length must be processed by the later composite pasting process before it can be used. In order to solve the above technical problems, this case proposes the following technical solutions:
