Abstract
The invention discloses a production process of melt-blown non-woven fabric, which comprises the following steps: a) extruding the mixture of PP particles, PP cooling master batches and PP powder from an extruder, controlling the temperature of four zones of the extruder at 160-220 ℃, then metering, and simultaneously filling high-temperature and high-pressure air for spinning; b) carding superfine fiber substances containing 20-50% of PET fibers, and then sending the superfine fiber substances and the spun mixture into a roller receiving device for lapping to obtain a semi-finished product; c) the upper and lower surfaces of the semi-finished product are respectively glued and compounded with the specification of 10-50g/m2The PP non-woven fabric is adopted, so that a product is obtained; the non-woven fabric produced by the process has the advantages that the fibers in the cross section direction are regularly arranged in a V shape, the filling ratio is high, and the non-woven fabric has ideal sound absorption rate, filling power and uniformity.
Description
Technical field
The invention belongs to textile technology field, be specifically related to a kind of production technology of V-arrangement melt spraying non-woven fabrics.
Background technology
Nonwoven product is seen everywhere in daily life; For example as diaper, sanitary napkin, rag and filtration series products or the like; The multinomial important performance of nonwoven product need be carried out by the superfine fibre net, and the quality that melts and sprays of superfine fibre net is the difficult point place in the melt spraying non-woven fabrics processing.
Melt spraying non-woven fabrics of the prior art; Mainly mixing back injection HTHP air melt spraying non-woven fabrics by terylene forms; The product that obtains is seen from cross-wise direction; The fiber alignment of mid portion is rambling irregular shape, is difficult to obtain desirable acoustic absorptivity, bulking intensity and uniformity, and packing ratio is lower.
Summary of the invention
The purpose of this invention is to provide a kind of melt spraying non-woven fabrics production technology, the fiber on the nonwoven fabric cross-wise direction of this explained hereafter is the V-arrangement of rule to be arranged, and packing ratio is higher, has desirable acoustic absorptivity, bulking intensity and uniformity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of production technology of melt spraying non-woven fabrics; Comprise the steps: a), the mixture of PP particle, PP cooling masterbatch and PP powder is extruded from extruder; Four district's temperature of extruder are controlled at 160-220 ℃; Measure then, the air that charges into HTHP simultaneously carries out spinning; B), the superfine fibre thing that will contain the PET fiber of 20-50% carries out combing, then with spinning after mixture send into the cylinder receiving system in the lump and carry out lapping, thereby obtain semi-finished product; C), semi-finished product are sprayed glue, be 10-50g/m in two compound respectively specifications in surface up and down then
2The PP nonwoven fabric, thereby obtain product.
Wherein, the PP particle accounts for 50-80% in the said step a), and the PP powder accounts for 5-15%.
Wherein, the PET fiber dimensious in the said step b) is 1.5D 6D.
The invention has the beneficial effects as follows: the V-arrangement that is rule according to the fiber on the nonwoven fabric cross-wise direction of this explained hereafter is arranged, and packing ratio is higher, has desirable bulking intensity and uniformity.
The specific embodiment
Below in conjunction with embodiment the present invention is done further explain.
The invention discloses a kind of production technology of melt spraying non-woven fabrics, comprise the steps:
A), will to contain 50-80%PP particle, 5-15%PP powder, surplus be that the mixture of PP cooling masterbatch is extruded from extruder, four district's temperature of extruder are controlled at 160-220 ℃, measure then, the air that charges into HTHP simultaneously carries out spinning;
B), will to contain 20-50%, specification be that the superfine fibre thing of the PET fiber of 1.5D-6D carries out combing, then with spinning after mixture send into the cylinder receiving system in the lump and carry out lapping, thereby obtain semi-finished product;
C), the compound specification of gluing being carried out on two surfaces about the semi-finished product respectively is 10-5Cg/m
2The PP nonwoven fabric, thereby obtain product.
Claims (3)
1. the production technology of a melt spraying non-woven fabrics is characterized in that, comprises the steps:
A), the mixture of PP particle, PP cooling masterbatch and PP powder is extruded from extruder, four district's temperature of extruder are controlled at 160-220 ℃, measure then, and the air that charges into HTHP simultaneously carries out spinning;
B), the superfine fibre thing that will contain the PET fiber of 20-50% carries out combing, then with spinning after mixture send into the cylinder receiving system in the lump and carry out lapping, thereby obtain semi-finished product;
C), the compound specification of gluing being carried out on two surfaces about the semi-finished product respectively is 10-50g/m
2The PP nonwoven fabric, thereby obtain product.
2. production technology according to claim 1 is characterized in that the PP particle accounts for 50-80% in the said step a), and the PP powder accounts for 5-15%.
