Problems solved by technology

China is a big country in luggage production. In 2009, China’s luggage industry reached an industrial scale of 87.8 billion yuan. There are many studies on the structure of suitcases in China, but the research on the lining materials of suitcases is very weak. Generally, other materials are borrowed. Industry materials to produce, such as waste cardboard materials, plastic boards, etc., but this is extremely unfavorable for the development of bags
[0003] Traditional luggage leather is mainly based on polyvinyl chloride and solvent-based polyurethane resin. Its characteristic is that when polyvinyl chloride is plasticized at high temperature, the plasticizer DOP (dioctyl phthalate) has certain Residues have certain harm to the human body, which is limited by the RECAH standard issued by the European Union
[0004] In addition, solvent-based polyurethane resin contains a large amount of organic solvents (dimethylformamide DMF, butanone MEK, toluene TOL, etc.), these organic solvents not only harm the health of workers, but also pollute the surrounding environment
[0005] At present, the environment-friendly water-based polyurethane resin mainly uses water as the solvent, does not produce waste water and waste gas, does not cause harm to the human body and the ecological environment, and reduces recycling equipment and energy consumption. Therefore, it is a solvent-based polyurethane and The best alternative material for PVC luggage leather, but there is no method to prepare coated fabrics for luggage with environmentally friendly water-based polyurethane resin, and this problem needs to be solved urgently

Embodiment 1

[0034] A preparation method for luggage fabric, comprising the following steps:

[0035] 1) Base fabric: It is composed of non-woven base fabric layer and glue formed in the base fabric layer after finishing, padding and heat setting treatment, and its weight is 1-2 times that of the base fabric layer;

[0036] 2) The first pass of waterproof drying: the base is placed in the liquid medicine for padding and then dried by a dryer. The liquid medicine consists of 5 parts by weight of fluorine-based water repellent, 4 parts by weight of penetrant and prepared from water;

[0037] 3) The first fire-proof drying: Soak the base cloth obtained in step 2) in the alum solution prepared by dissolving 1 kg of alum powder in 10-11 liters of water for 10-15 minutes, take it out naturally Obtain fireproof base cloth after drying;

[0038] 4) Initial calendering: calendering the fire-proof and dried base fabric with a calender at 160°C;

[0039] 5) The second time of waterproof drying: th...

Abstract

The invention discloses a preparation method of a luggage case fabric. The preparation method comprises the following steps: (1) producing a basic cloth; (2) drying in a waterproof manner; (3) dryingin a fireproof manner; (4) calendaring; (5) re-performing the waterproof drying again; (6) re-performing the fireproof drying again; (7) re-calendaringagain; (8) coating and forming a film; and (6) waxing. The preparation method of the luggage case fabric is simple in process and suitable for the industrialized production; and moreover, the prepared environment-friendly case coating fabric is highin surface flatness, soft in hand feeling, and wide in market application prospect.

Description

technical field [0001] The invention relates to the field of suitcases, in particular to a method for preparing a suitcase fabric. Background technique [0002] With the continuous improvement of people's production and consumption levels, various bags have become indispensable accessories in people's lives.
