Problems solved by technology

However, the dyeing uniformity and color fastness of non-woven microfiber leather are not good, the fibers of the fleece are easy to fall off, and the anti-pilling performance is poor.
Moreover, due to emphasizing on simulating the internal structure of animal skin, there are deficiencies in appearance color, elasticity, deformation resistance, etc.

Embodiment Construction

[0032] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0033] A kind of preparation method of weft-knitted suede super imitation leather fabric of one embodiment of the present invention, comprises the following steps:

[0034] Step 1, preparation of base fabric: use 105D / 36F sea-island composite yarn as raw material, use air layer tissue to weave on a double-sided circular knitting machine with 28 needles, 32 needles, 36 needles or 40 needles to obtain gray cloth; specifically, the gray cloth The weaving diagram of the organizational structure is as follows figure 1 As shown, the triangular arrangement diagram of the upper machine is as follows figure 2 As shown, the air layer is knitted by the 6-w...

Abstract

The invention discloses a preparation method of weft-knitted chamois suede super-imitated leather fabric. Sea-island filament microfibers are used as a raw material and are woven into grey cloth on adouble-sided circular knitting machine, the texture structure of the grey cloth is double-rib texture or air layer texture, and the grey cloth is subjected to post-finishing process treatment to obtain super-imitated leather base cloth; the super-imitated leather base cloth is soaked in polyurethane slurry, excess slurry is rolled out, and then the super-imitated leather base cloth is cured, so that both sides of the super-imitated leather base cloth form polyurethane leather films; and the obtained super-imitated leather base cloth with the polyurethane leather films formed is sequentially subjected to water washing, drying, double-sided grinding, dyeing process, shaping, brushing and finished product shaping to obtain a finished product. The weft-knitted chamois suede super-imitated leather fabric is soft in hand feeling, excellent in resilience and deformation resistance, rich in color and good in anti-pilling performance, and the practical application value in the fields of clothing and the like is improved.

Description

technical field [0001] The invention relates to the technical field of super imitation leather fabric manufacturing, in particular to a preparation method of a weft-knitted suede super imitation leather fabric. Background technique [0002] With the continuous deterioration of the ecological environment, countries all over the world are aware of the importance of protecting the environment and animals, and it has become a trend to use artificial leather instead of animal leather. However, although artificial leather imitates the appearance effect of genuine leather to a certain extent, there are still certain differences in its elastic recovery and extensibility. Existing artificial leather cannot simultaneously take into account the lifelike imitation of appearance and performance. [0003] At present, most of the base fabrics of microfiber artificial leather are non-woven fabrics, and the three-dimensional network structure of the non-woven fabrics endows the non-woven fa...
