Abstract

The present invention disclose a kind of non-woven fabrics without yarn loop bonding technique, raw material cotton is successively by grabbing pine, dedusting, combing, paving cotton, braiding, immersion, leveling, the process processing of thermocompression forming, finally obtained non-woven cloth products have high-hygroscopicity, surfacing not hair loss, feel is full and soft, can be widely used for the production of the reprocessing products such as sanitary napkin, cotton pads and beauty mask.The non-woven fabrics without yarn loop bonding technique, needlework of the cotton yarn itself being had in knitting process using raw material cotton as braiding, save the cost can not only improve the fibre density of needlework, it can avoid frequent broken yarn phenomenon during subsequent thermocompression forming simultaneously, improve product quality.

Description

A kind of non-woven fabrics without yarn loop bonding technique
Technical field
The present invention relates to non-woven loop bonding application fields, and in particular to be a kind of non-woven fabrics without yarn loop bonding technique.
Background technique
Non-woven fabrics is commonly used to fabricate into the amenities such as napkin, towel and cotton pads to be used in people's lives In field, but find that the water imbibition of non-woven fabrics is not high in use, and be easy to appear soft flocks absorption showing on the skin As causing skin pore blocking even allergy.And the production of non-woven fabrics generallys use water jet process, the life of water jet process at present It is high to produce equipment cost, complex technical process, it is difficult to popularize in medium-sized and small enterprises.
Summary of the invention
The purpose of the present invention is to provide a kind of non-woven fabrics without yarn loop bonding technique, and technical process is simple, at low cost, production Obtained non-woven fabrics has high-hygroscopicity, and hair loss, feel be not full and soft for surfacing.
In order to achieve the above objectives, solution of the invention is:
A kind of non-woven fabrics without yarn loop bonding technique, comprising the following steps:
(1) it grabs pine: raw material cotton is grabbed by pine using automatic plucker；
(2) dedusting: the raw material cotton in step (1) after grabbing pine is transported in dust cleaning case and removes the raw material cotton The dust and impurity little particle of upper attachment, to improve the cleanliness of product；
(3) it combs: the raw material cotton feeding carding machine in step (2) Jing Guo dedusting is combed into thin netted cotton Layer；
(4) it spreads cotton: the cotton layer in step (3) being delivered on paving cotton device and is overlapped repeatedly and is paved into cotton layer, The cotton dosage of the cotton layer is 20~400g/m2；
(5) it weaves: the cotton layer in step (4) being delivered on knitting device and carries out braiding reinforcing, the braiding Reinforce the yarn that needlework used itself are had by the cotton layer, the needlework density that the braiding is reinforced for 10~25 needles/ Inch；
(6) it soaks: by after the cotton layer of braiding carries out immersion processing, then vacuum dehydration, so that the cotton Layer, which is sufficiently shunk, becomes full substantial；
(7) flatten: by the two sides of the cotton layer by immersion, successively roll compacting is arranged, so that the surface of the cotton layer Become smooth consolidation；
(8) thermocompression forming: will be delivered to calender progress thermocompression forming by the cotton layer of leveling and obtain semi-finished product, The temperature of the thermocompression forming is 80~200 DEG C, and the pressure of the thermocompression forming is 1-2 kilograms；
(9) it carries out disinfection, wound to get to the nonwoven after cooling down the semi-finished product obtained by step (8) at room temperature Cloth.
In step (1), the raw material cotton is cotton or the raw material cotton is the mixing that cotton and terylene mix Perhaps the raw material cotton is that perhaps the raw material cotton is mixing cotton or the original that cotton and nylon mix to nylon to cotton Material cotton is the mixing cotton that cotton and bamboo fibre mix.
In step (4), the cotton dosage of the cotton layer is 260g/m2。
In step (5), the braiding reinforcing is first to tick the laminated yarn of the cotton by the groove pin of the knitting device Then line chooses the yarn on groove pin by the looper of the knitting device, complete primary braiding, repeatedly, just complete to institute The loop bonding for stating this one side of cotton layer is reinforced, then the yarn of the cotton layer another side is ticked by the groove pin of the knitting device, Then the yarn on groove pin is chosen by the looper of the knitting device, repeatedly, just complete to the cotton layer this is another Face into loop bonding reinforce.
In step (5), the needlework density that the braiding is reinforced is 20 needles/inch.
In step (6), the speed of the immersion processing is 5~40 ms/min.
In step (8), the temperature of the thermocompression forming is 130 DEG C, and the pressure of the thermocompression forming is 1.5 kilograms.
After the knitting process of step (5), remaining cotton-wool is recycled by exhaust column and is conveyed again the cotton layer It is recycled to the automatic plucker.
After adopting the above technical scheme, a kind of non-woven fabrics of the present invention without yarn loop bonding technique, on the one hand, in knitting process Needlework of the cotton yarn being had using cotton layer itself as braiding, save the cost can not only improve the fibre density of needlework, together When can avoid frequent broken yarn phenomenon during subsequent thermocompression forming, improve product quality.On the other hand, raw material cotton Successively by grabbing pine, dedusting, combing, paving cotton, braiding, immersion, leveling, the process processing of thermocompression forming, finally obtained product With high-hygroscopicity, surfacing not hair loss, feel is full and soft, can be widely used for sanitary napkin, cotton pads and beauty mask Etc. reprocessing products production.
