Problems solved by technology

However, low-melting point fibers are completely composed of low-melting point components, which have low tensile strength, high thermal shrinkage, and poor elastic modulus. Therefore, the requirements for non-woven fabric equipment including cleaning, mixing, and carding are also high.

Embodiment 1

[0025] Embodiment one: a kind of production technology of the car carpet that adopts indeterminate island sea-island fiber nonwoven fabric trim, is characterized in that, comprises the following steps:

[0026] (1) Opening and mixing: 60% polyester fiber and 40% edge material of adventitious island fiber are loosened by two rough opening machines in the bale opener, then sent to the large warehouse for mixing, and then refined loosening machine;

[0027] (2) Carding and laying: the finely opened mixed fiber is fed into the carding machine through the cotton feeding box and belt scale, and the cylinder and work roller of the carding machine card the mixed fiber to form a uniform single-layer cotton web. The weight of the mesh is 25g / ㎡; the layering machine lays a single layer of cotton mesh into a 30-layer thick cotton mesh for output;

[0028] (3) Acupuncture: The thick cotton net output by the net laying machine is fed to the pre-acupuncture machine by the feeder for pre-ent...

Embodiment 2

[0032] Embodiment two: a kind of production technology of the automobile carpet that adopts indeterminate island sea-island fiber nonwoven fabric trim, is characterized in that, comprises the following steps:

[0033] (1) Opening and mixing: After opening 95% of polyester fiber and 5% of Adventitious island fiber edge material in the bale opener through two rough openers, they are sent to the large warehouse cotton blender for mixing, and then refined loosening machine;

[0034] (2) Carding and laying: the finely opened mixed fiber is fed into the carding machine through the cotton feeding box and belt scale, and the cylinder and work roller of the carding machine card the mixed fiber to form a uniform single-layer cotton web. The weight of the mesh is 75g / ㎡; the layering machine lays a single layer of cotton mesh into a 6-layer thick cotton mesh for output;

[0035] (3) Acupuncture: The thick cotton net output by the net laying machine is fed to the pre-acupuncture machine b...

Embodiment 3

[0039] Embodiment three: a kind of production technology of the automobile carpet that adopts indeterminate island sea-island fiber nonwoven fabric trim, is characterized in that, comprises the following steps:

[0040] (1) Opening and mixing: After opening 65% of polyester fiber and 35% of Adventitious island fiber edge material in two rough opening machines in the bale opener, they are sent to the Dacang Cotton Mixer for mixing, and then finely loosening machine;

[0041] (2) Carding and laying: the finely opened mixed fiber is fed into the carding machine through the cotton feeding box and belt scale, and the cylinder and work roller of the carding machine card the mixed fiber to form a uniform single-layer cotton web. The weight of the mesh is 50g / ㎡; the layering machine lays a single layer of cotton mesh into a 20-layer thick cotton mesh for output;

[0042] (3) Acupuncture: The thick cotton net output by the net laying machine is fed to the pre-acupuncture machine by th...

Abstract

The invention relates to a vehicle carpet using unfigured island non-woven open-edge waste material; the preparation method comprises the following steps: 1, opening and mixing: opening polyester fiber 60-95% and unfigured sea island fiber open-edge waste material 5-40% by two rough openers, sending the material into a large chamber cotton blender for mixing, and opening the material by a fine opener; 2, carding and netting: feeding the finely opened mixture fibers into a carding machine, carding the fibers so as to form uniform single layer cotton web, and using a lapping machine to lap the single layer cotton web into thick cotton web, and outputting the thick cotton web; 3, needling: using a feeder to feed the thick cotton web, outputted by the lapping machine, into a pre-needle machine for pre-winding reinforcement, using a main needle machine to process the material so as to obtain semi-finished product, and forming the coiled material of needed gram weight by processing the semi-finished product on a coiler; 4, baking: baking the needled coiled material at the temperature of 120-200 DEG C for 2-8 minutes, thus melting the low density polyethylene on the outer layer of the unfigured sea island fiber. The unfigured island non-woven open-edge waste material can be used in the non-decrement field, thus reducing resource waste.

Description

technical field [0001] The invention relates to an automobile carpet which adopts indeterminate island nonwoven fabric trim, in particular to an automobile carpet which adopts indeterminate island nonwoven fabric trim instead of low melting point fiber. Background technique [0002] Low-density polyethylene-nylon 6 blended adventitious island microfiber in the tanning industry is a special fiber for superfine ultra-real leather base cloth. The existing process is to remove the island component through weight reduction, leaving only the sea group points to obtain ultrafine denier fibers that cannot be obtained by traditional spinning processes, that is to say, only island components are used. Due to the large difference in properties between low-density polyethylene and nylon 6, it has always been a difficult problem to trim the edges and waste cloth of the two-component blended indeterminate microfiber nonwovens, and the fibers that are loosened are generally no longer used ...
