Problems solved by technology

[0002] Although the ordinary spunbonded nonwoven fabrics have good physical and mechanical properties at present, it can also be soft by adding soft masterbatch and elastomers to the raw materials, but the products still have no fluffy feeling.
Moreover, the addition of soft masterbatch will affect the stability of production, and the price of soft masterbatch is much higher than other raw materials, which greatly increases the production cost; As the skin layer, the polymer component B is used as the core layer, which is compounded along the fiber axis in this way
The softness and physical properties of the skin-core two-component spunbonded nonwoven fabric produced by this process have not been greatly improved, nor can it meet the requirements of softness and fluffiness, and the production speed is slow and the production capacity is low.

Embodiment 1

[0025] The production process of the two-component spun-bonded filament nonwoven material in parallel with cashmere comprises the following steps:

[0026] S1: Raw material feeding: Cut two groups of raw materials with different melt indexes into the feeding machine. The raw materials are PP and PE or PP and PP or PP and COPP or PE and PET or PP and PET or PET and COPP, and the raw materials Before feeding, it needs to be dried and sliced. The drying temperature is 100 degrees, and the drying time is 8 hours. Then put it into a ball mill for ball milling, so that the diameter of the raw material is between 5-15 mm;

[0027] S2: Extrusion hot melt: Put two groups of raw materials into two groups of screw extruders respectively. The temperature is controlled at 170 degrees and 180 degrees, and two sets of melts are obtained, the temperatures are 160 degrees and 170 degrees respectively;

[0028] S3: Melt distribution: Pour the two sets of melts extruded in step S2 into two sets...

Abstract

The invention discloses a production technique of a lint-lifting parallel dual-component spun-bonded fiber filament non-woven material in the technical field of non-woven cloth production. The production technique of lint-lifting parallel dual-component spun-bonded fiber filament non-woven material includes steps of S1, raw material feeding; S2, extrusion and hot melting; S3, melt distribution; S4, parallel type jetting; S5, lint lifting; S6, printing; S7, hot wind shaping; S8, cooling and packaging. Through distributing and combining two polypropylene raw materials with different melt indexesto be a fiber in parallel through a distribution plate, the raw materials are stretched at different levels in the stretching process due to different physical performances of the raw materials, thefiber can be naturally rolled, the non-woven cloth is loosened; the production technique solves the requirement of the existing non-woven cloth health medical product on product softness performance and high fluffy performance; through an online lint lifting device, the parallel dual-component product is implemented with lint lifting, thus the product appearance is increased, and the product has third dimension.

Description

technical field [0001] The invention relates to the technical field of production of nonwoven fabrics, in particular to a production process of a two-component spun-bonded filament nonwoven material juxtaposed with cashmere. Background technique [0002] Although the current common spunbonded nonwoven fabric has good physical and mechanical properties, it can also be soft by adding soft masterbatch and elastomer to the raw material, but the product still has no fluffy feeling. Moreover, the addition of soft masterbatch will affect the stability of production, and the price of soft masterbatch is much higher than other raw materials, which greatly increases the production cost; As the skin layer, the polymer component B is used as the core layer, which is compounded along the fiber axis in this arrangement. The softness and physical properties of the skin-core two-component spunbonded nonwoven fabric produced by this process have not been greatly improved, and they cannot me...
