2. non-woven fabrics is made bag: using step 1. form out the face of singing as bag inner surface and process the bag with cavity volume.

Further, step 1. in enter cloth operation cloth speed of entering be 20-30m/min.

Further, step 1. singe in operation, flame and cloth cover angle are 20 °-60 °, and temperature of singing is 500 DEG C-700 DEG C.

Further, this non-woven fabrics is polyster fibre or the non-woven conventional chemical fibre of other fusing point below 400 DEG C, and fineness at 1.5D-6D, and has at least three kinds of different fineness.

Further, the thickness that 1. step forms out with the non-woven fabrics in the face of singing is 1mm-5mm, and density is 0.15-0.35g/cm ³.

After adopting said structure, a kind of tree planting bag that the present invention relates to and production method thereof, it is owing to adopting the non-woven fabrics of fineness shape in gradient, therefore when singing operation, because cloth cover filoplume melting speed is different, the melting of fine, soft fur plumage is fast, and the melting of coarse wool plumage is slow, therefore make filoplume melting set point more tight in cloth cover arrangement, make cloth cover hole less.In addition, compared to traditional singeing flow process, lack the bristle operation after singing, therefore filoplume melting set point can have been protected, effectively reduce cloth cover porosity.

Based on the characteristic of non-woven fabrics itself, make bag in the tree planting bag that the present invention relates to have good permeability and can absorb water after watering and help the feature of water storage; In addition, inner surface due to this bag is the face of singing, and this filoplume melting of singing on face condenses in cloth cover makes cloth cover hole diminish, sandslide when can effectively prevent from watering, improve the survival rate of trees and effectively extend watering time interval, thus reducing managerial work amount.

Compared with prior art, the present invention not only has gas permeability concurrently and prevents sandslide, and it only needs to singe to non-woven fabrics to process, and also has effect that production process is simple and cost is low.

Embodiment

In order to explain technical scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.

As depicted in figs. 1 and 2, it is a kind of tree planting bag 100 that the present invention relates to, and comprises bag 1, this bag 1 is cylinder at the present embodiment, and adopting terylene needle punched non-woven fabrics to make, this bag 1 has outer surface 11 and inner surface 12, and this inner surface 12 is the face of singing formed through process of singing.

Like this, the present invention is based on the characteristic of non-woven fabrics itself, make whole bag 1 have good permeability and can absorb water after watering and help the feature of water storage; In addition, inner surface 12 due to this bag 1 is the face of singing, and this filoplume melting of singing on face condenses in cloth cover makes cloth cover hole diminish, sandslide when can effectively prevent from watering, improve the survival rate of trees and effectively extend watering time interval, thus reducing managerial work amount.

Preferably, this tree planting bag 100 also comprises handle 2, this bag 1 has bottom 13 and opening 14, and this handle 2 is shaping by bag 1 cutting towards the protruding outside of bag 1.Because this handle 2 is that bag 1 cutting is shaping, it sews up compared to other handle formed, and has better structural strength.In the present embodiment, this handle 2 has a pair that is symmetric.

In use, nursery stock root is put into bag, then add soil and can realize planting nursery stock in originally be inconvenient to the to plant place of trees such as such as roof.

The present invention also provides a kind of production method of tree planting bag, is made up of following steps:

1. on non-woven fabrics, the face of singing is molded: the non-woven fabrics choosing fineness shape in gradient, successively through entering cloth, bristle, singing, cool and forming in the side of non-woven fabrics face of singing after cropping;

2. non-woven fabrics is made bag: using step 1. form out the face of singing as bag inner surface and process the bag with cavity volume.

Said method is owing to adopting the non-woven fabrics of fineness shape in gradient, therefore when singing operation, because cloth cover filoplume melting speed is different, the melting of fine, soft fur plumage is fast, and the melting of coarse wool plumage is slow, therefore makes cloth cover hole less after making filoplume melting condense in cloth cover.In addition, compared to traditional singeing flow process, lack the bristle operation after singing, namely after singing, directly cooled cropping, therefore filoplume melting set point can have been protected, effectively reduce cloth cover porosity.

Preferably, step 1. in enter cloth operation cloth speed of entering be 20-30m/min.So while guarantee production efficiency, can ensure that again the time of singing abundant, makes all filoplume meltings be agglomerated to cloth cover.In addition, step 1. singe in operation, flame and cloth cover angle are preferably 20 °-60 °, flame is reduced to the injury of cloth cover fiber while making filoplume melting, angle is crossed conference and is melted disconnected cloth cover few fibers, destroys face construction, and the too small impact of angle is singed efficiency; Temperature of singing then is preferably 500 DEG C-700 DEG C, and in general, singe in operation in tradition, conventional temperature of singing is more than 800 DEG C, and mainly because its object of singing is different, it is for removing cloth cover filoplume, makes cloth cover bright and clean; But the present invention preferably adopts 500 DEG C-700 DEG C, thus can available protecting cloth cover filoplume not burned and filoplume melting is condensed to cloth cover, easily make when temperature is too high filoplume burn, do not reach reduction cloth cover porosity effect; Temperature is too low, may make cloth cover filoplume not melting or melting insufficient, impact is singed efficiency, reduces Chinese zodiac efficiency and increases cost.

Particularly, this non-woven fabrics is terylene fibre or the non-woven conventional chemical fibre of other fusing point below 400 DEG C.The thickness that 1. step forms out with the non-woven fabrics in the face of singing is 1mm-5mm, and density is 0.15-0.35g/cm ³.
