Abstract
The invention relates to a production method for synthetic leather containing degradable bamboo fiber, which comprises the following steps: firstly, selecting natural bamboo fiber with excellent performance, mixing the natural bamboo fiber and chemical synthetic leather fiber (terylene and nylon) according to certain proportion, conducting cotton laying, cotton stacking, prickling, sizing and the other processes on the mixture so as to obtain degradable bamboo fiber non-woven substrate conforming to the production needs of the synthetic leather, and then utilizing the wet production process and the dry production process of the synthetic leather for preparing the synthetic leather containing degradable bamboo fiber. Compared with the prior art, the synthetic leather prepared by the production method has the following beneficial effects: the degradable bamboo fiber is contained in the synthetic leather, so that the content of the chemical fiber is reduced, further the reduction of environmental pollution is facilitated, and the low carbon and environmental production are achieved, and the synthetic leather has the advantages specially shown by the bamboo fiber: moisture absorption and perspire removing, bacteria inhabitation, deodorization and the like.
Description
Technical field
The present invention relates to a kind of production method that contains the biodegradable fiber synthetic leather, particularly a kind of production method that contains degradable bamboo fibre synthetic leather.
Background technology
At present synthetic leather field great majority adopt with 100% chemical synthetic fiber as the nonwoven fabric of (terylene, nylon) as base, because the degradable difficulty of chemical fibre is big, easily environment produce is polluted, and most of chemical fibre is because it can not compatibility cause dress uncomfortable to skin.Bamboo fibre is emerging in recent years a kind of Biodegradable fibers, it is that raw material is refined into bamboo pulp through catalyzing hydrolysis, alkaline process and multistage bleaching with the bamboo, the regenerated celulose fibre that the process spinning is made, bamboo fibre intensity is big, toughness and ABRASION RESISTANCE are stronger, have moisture absorbing and sweat releasing, bacteriostatic deodorizing, soft, characteristic such as dyeability is good.What the present invention introduced is a kind of production method that contains the bamboo fibre synthetic leather.
Summary of the invention
Technical problem to be solved by this invention provides with a kind of and contains bamboo fibre to substitute the parts of traditional chemical synthetic fiber be the production method of the synthetic leather of base, makes synthetic leather have the comfortable characteristic of biological environmental production.
For solving the problems of the technologies described above, the present invention realizes as follows: a kind of production method that contains degradable bamboo fibre synthetic leather of the present invention, its production method step comprises: at first mix with chemical synthesis leather fiber (terylene, nylon) in certain proportion by the bamboo fiber of selecting excellent performance, make and meet synthetic leather and produce needed degradable bamboo fibre nonwoven fabric base through spreading technologies such as cotton, folded cotton, acupuncture, typing, again through synthetic leather wet process technique, dry technology for production make contain degradable bamboo fibre synthetic leather.
Good effect of the present invention: a kind of production method that contains degradable bamboo fibre synthetic leather of the present invention, compared with the prior art, beneficial effect of the present invention is embodied in:
1, contains the degradable bamboo fibre in the synthetic leather, reduced the content of chemical fibre, help reducing environmental pollution, low-carbon environment-friendly.
2, synthetic leather has characteristics such as the peculiar moisture absorbing and sweat releasing of bamboo fibre, bacteriostatic deodorizing.
