Problems solved by technology

However, the polyimide fiber itself has a golden yellow color. At present, a limited number of colors are produced by dope dyeing in the spinning process, which greatly restricts the application and promotion of the fiber.

Embodiment

[0031] The present invention adopts 14.5tex, 100% polyimide yarn to weave on a double-sided circular knitting machine, one side is brushed, and the brushed fabric is dipped and rolled twice with a pre-treatment liquid with strong hydrophilicity and hygroscopicity, and at the same time, the pre-treatment liquid is well controlled. The liquid-carrying rate of the treatment liquid adopts nano-scale paint ink for DuPont digital printing to prevent the large pigment particles in ordinary paint from causing poor rubbing fastness. On the non-velvet side of the fabric, white ink is first used as a primer, and then digital printing is carried out, and infrared drying is used to fully cross-link the ink and yarn. After testing, the fabric thermal resistance = 0.17334㎡·k / w, Cro value = 1.11834clo, thermal conductivity = 0.11538w / (m·k), heat transfer coefficient = 5.769w / (㎡·k), which is the existing Among the fibers, it is the fabric with the best heat preservation and heat insulation. It...

Abstract

The invention discloses a production method of an ultra-warmth digital printing knitted fleece fabric. The method comprises the following steps of gray fabric weaving, single-face napping, pre-treatment, white ink bottoming, first-time drying, digital printing, second-time drying, baking, finished product packaging and detecting. By adopting 100% polyamide yarn with the density being 14.5 tex, weaving is performed on a two-face circular knitting machine, single-face napping is performed, the napped fabric is soaked and rolled into a pretreatment solution with high hydrophilicity and moisture absorption two times, meanwhile, the liquid carrying rate of the pretreatment solution is controlled, a Dupont nanometer coating ink for digital printing is adopted, and the phenomenon that friction firmness is poor due to large pigment particles in a common coating is avoided. White ink bottoming is performed on the non-napping face of the fabric at first, then, coating digital printing is performed, infrared drying is adopted, and sufficient cross linking is performed between ink and the fabric.

Description

technical field [0001] The invention belongs to the field of fabrics in the textile industry, and in particular relates to a production method of a super-warm digitally printed knitted fleece fabric. Background technique [0002] Polyimide fiber has high strength, high modulus and high temperature resistance. It is an important high-performance fiber. Its molecular main chain contains imide ring groups, referred to as PI fiber. At present, there are mainly Gaoqi Polyimide Materials Co., Ltd. in Changchun, Jilin Province and Aoshen New Materials Co., Ltd. in Lianyungang, Jiangsu Province that can carry out large-scale and industrialized production of polyimide fibers in China. Based on the excellent properties of high temperature resistance, flame retardancy, mechanical and chemical resistance, polyimide fiber has become one of the hot materials for producing safety protection products such as heat insulation and fire protection, and is favored by the market. However, the po...
