Embodiment 1

[0031] A kind of production technology of environment-friendly imitation calfskin fabric involved in the present embodiment, comprises the following steps:

[0032] S1. Preparation of the surface layer: The environmentally friendly suede fabric woven by KARL-MAYER high-speed warp knitting machine is prepared through the processes of napping, dyeing, drying, sanding, combing, shaping, printing, and bronzing. The color to be dyed, the pattern of printing, and the patterns and textures selected by the bronzing process are all based on actual needs. The pattern pattern selected by the bronzing process is imitation calfskin pattern.

[0033] S2. Preparation of the bottom layer: KARL-MAYER high-speed warp knitting machine is used to weave the warp knitted fabric, and the bottom layer warp knitted fabric is dyed, napped and shaped to prepare warp knitted fleece.

[0034] S3. Composite: The bottom layer and the surface layer are composited by the oil-glue composite process. The glue...

Embodiment 2

[0053] The difference between the production process of the environment-friendly imitation calfskin fabric involved in this embodiment and the first embodiment is that before the bottom warp-knitted flannelette is compounded with the surface layer imitation suede fabric through the oil-glue compounding process, it is first passed through PU resin and a reinforcement layer. Composite, the composite layer used is a nylon grid cloth with a grammage of 5 grams per square meter.

Abstract

The invention discloses a production technology for environment-friendly imitated calf skin leather. The production technology comprises the following steps: S1) preparing an environment-friendly chamois fabric as a surface layer; S2) preparing a warp knitted flannelette as a bottom layer; S3) compounding: adopting a factice compounding process for compounding the surface layer with the bottom layer; S4) washing: washing the compound fabric acquired in the step S3) with water and drying. According to the production technology for environment-friendly imitated calf skin leather disclosed by theinvention, superfine raw material dacron is used, so that the hand feeling of natural chamois can be acquired without alkali decrement treatment for the fabric in the whole dyeing process and the pollution caused by emission of decrement sewage can be reduced; the clean environment-friendly production of textile fabric can be achieved in the whole production process; through the specific production technology, the environment-friendly super-soft imitated leather fabric can be produced.

Description

technical field [0001] The invention relates to the technical field of textile fabric production, in particular to an environment-friendly production process of imitation calfskin fabric. Background technique [0002] When existing fabrics with imitation natural cowhide feel, in the production process, it is necessary to carry out alkali reduction treatment on the fabrics, so that the fabrics have the effect of imitating cowhide. Due to the use of alkali to treat the fabric, the production process is polluted by the discharge of alkali-containing sewage. Contents of the invention [0003] The purpose of the present invention is to provide an environment-friendly production process of imitation calfskin fabric, which makes the production process of imitation cowhide fabric environment-friendly and achieves clean and environment-friendly production of textile fabrics. [0004] For solving the problems of the technologies described above, the purpose of the present invention...
