Processing technology of waterproof oil-proof ironing-resistant TPU table cloth cushion

Abstract

The invention discloses a processing technology of a waterproof oil-proof ironing-resistant TPU table cloth cushion. The processing technology takes a TPU composite film, a base fabric and a PUR hot melt adhesive as raw materials, and adopts a hot-pressing composite processing mode for forming. The processing technology mainly comprises the four steps of raw material preparation, hot-melting compounding, trimming and rolling, and cutting and packaging. The processed table cloth finished product has the characteristics of no washing, easy cleaning, oil resistance, water resistance and the like;and the production and manufacturing process is more environment-friendly. According to the processing technology, the two different materials of the TPU composite film and the bottom fabric can be well combined, the product is a non-toxic environment-friendly material, and the processing technology can be applied to the production and manufacturing of table cloth, can also be applied to other technical fields, and has great economic benefits.

Description

technical field [0001] The invention relates to the technical field of composite tablecloth manufacturing, in particular to a processing technology for a waterproof, oil-proof and scald-resistant TPU tablecloth pad. Background technique [0002] Now the tablecloths on the market are mainly made of PVC material tablecloths and fabric tablecloths. PVC material tablecloths are mainly made of PVC granules, which are full of plastic and feel stiff. When used in summer, the smell of formaldehyde is strong and pungent, which is not satisfactory. Environmental requirements, at the same time, the printing color is not rich enough, the color is not bright enough and relatively dull, in case of low temperature or winter season, it will be as hard as a stone, and the four corners are often accompanied by damaged spikes during winter transportation. After 3 years, the material is prone to embrittlement and is easy to be torn; while the fabric tablecloth is mainly made of polyester, cotto...

Problems solved by technology

[0002] Now the tablecloths on the market are mainly made of PVC material tablecloths and fabric tablecloths. PVC material tablecloths are mainly made of PVC granules, which are full of plastic and feel stiff. When used in summer, the smell of formaldehyde is strong and pungent, which is not satisfactory. Environmental requirements, at the same time, the printing color is not rich enough, the color is not bright enough and relatively dull, in case of low temperature or winter season, it will be as hard as a stone, and the four corners are often accompanied by damaged spikes during winter transportation. After 3 years, the material is prone to embrittlement and is easy to be torn; while the fabric tablecloth is mainly made of polyester, cotton and linen, and contains Teflon additives to play a waterproof role. It does not have oil-proof function in daily use and this kind of tablecloth The price is more expensive; in addition, when this type of tablecloth is washed more than 3 times, the waterproof effect will become weaker and weaker until it disappears, which is not resistant to dirt and is not conducive to care
