Specific detection data is shown in Table 1-2.
Experiment 1
The plant of spun lacing nonwoven Flocked fabric is detected according to GB/T13775-92 " cotton, fiber crops, spun silk woven fabric abrasion test method "
Suede fastness (secondary).
Experiment 2
Record the dosage (g/m of above embodiments and the thermosol in comparative example2)。
Table 1
Table 2
It can be obtained according to embodiment 1 in table 1 and table 2 and the data of comparative example 1, at soaked processing and centrifugal dehydration
Reason be easy to be eluted out so that being bonded unstable villus on spun lacing nonwoven Flocked fabric so that production gained spun lacing without
The flocking fastness for spinning Flocked fabric improves, so that spun lacing nonwoven Flocked fabric is not easy lint.
It can be obtained according to the data of embodiment 1-3 and comparative example 2-3 in table 1 and table 2, in the speed of 10m/min-14m/min
It spends in range, transmission speed of the spunlace non-woven cloth in flocking process is faster, and flocking efficiency is higher, so that its hot melt adhesive
Glutinous agent dosage increases with the raising of efficiency, but flocking fastness has and slightly decreases simultaneously；When transmission speed is lower than 10m/min
When, it is easy the certain thickness villus of accumulation on spunlace non-woven cloth, so that the dosage of thermosol increases, but is covered on
Villus on the villus of spunlace non-woven cloth surface is not easy to contact with thermosol, so that flocking fastness is declined；When
When transmission speed is higher than 14m/min, villus does not have enough time also being sticked on spunlace non-woven cloth, and spunlace non-woven cloth is just communicated off,
So that the closeness of villus reduces, so that the dosage of thermosol is reduced, meanwhile, villus does not have enough time also cementing, water
Prick nonwoven cloth is communicated off, so that flocking fastness has a degree of decline.
It can be obtained according to the data of embodiment 1 and comparative example 4-5 in table 1 and table 2, in gradient by the indoor temperature of flocking
Incremental setting, is conducive to spun lacing nonwoven Flocked fabric and thermosol better adapts to temperature change, to be conducive to suede
Hair is preferably sticked on spun lacing nonwoven Flocked fabric, so that flocking fastness improves.
It can be obtained according to embodiment 1, the data of embodiment 4-5 and comparative example 6-7 in table 1 and table 2, at 80 DEG C -100 DEG C
In range, the temperature in calendering process is higher, thermosol easier moulding in calendering process, so that hot melt gluing
Agent is easier by densification reality, so that dosage required for thermosol is fewer, while making the closely knit of thermosol
Degree is more preferable, so that the flocking fastness of spun lacing nonwoven Flocked fabric is higher；When calendering temperature is lower than 80 DEG C, thermosol is not
It is easy moulding, thus need to increase the dosage of thermosol with anchoring villus, so that the dosage of thermosol is increased,
The thermosol being added simultaneously is difficult to uniformly mutually mix with original thermosol, so that flocking fastness has centainly
Decline；When calendering temperature is higher than 100 DEG C, thermosol may will become molten condition, to be easy to happen colloidal sol leakage
The case where glue, so that the dosage of thermosol is risen, so that flocking fastness is declined.
It can be obtained according to embodiment 1 in table 1 and table 2 and the data of comparative example 8, by calendering processing so that thermosol
Compactness raising effectively reduce the dosage of thermosol, the compactness of thermosol makes flocking firm while raising
Degree significantly improves, and spun lacing nonwoven Flocked fabric is made to be not easy lint while being conducive to economize on resources.
It can be obtained according to embodiment 1, embodiment 6-7 and the data of comparative example 9 in table 1 and table 2, by the way that thermoplastic poly is added
Urethane elastomer rubber and silicon powder are conducive to the toughness and intensity that enhance thermosol, so that thermosol is anti-
Tensile strength and shear strength enhancing, so that thermosol is not easily susceptible to cracking during being patted, to be conducive to
Improve the flocking fastness of spun lacing nonwoven Flocked fabric；By the way that silane coupling agent is added, be conducive to improve inorganic in thermosol
Compatibility between filler and organic solvent, each component dispersion mixing be conducive in thermosol is uniform, so that silicon
Micro mist and thermoplastic polyurethane elastomer rubber preferably play a role, and are conducive to the shear strength for improving thermosol
And tensile strength, meanwhile, the hydroxyl on silanol that silane coupling agent hydrolyzes to form be easy on ethylene-acrylic acid copolymer
Carboxyl reaction so that molecule chain elongation, form cross-linked network makes so that the tensile strength of thermosol enhances
It obtains thermosol and is not easy the cracking that comes unglued during being patted, so that the flocking fastness of spun lacing nonwoven Flocked fabric improves.
It can be obtained according to embodiment 1, the data of embodiment 6-7 and embodiment 8-10 in table 1, by the way that toughener and lotus is added
Ye Fen can enhance the tensile strength and shear strength of thermosol to a certain extent, so that spun lacing nonwoven is planted
The flocking fastness of flannelette improves.
By the way that toughener is added, be conducive to the toughness for improving thermosol, so that the tensile strength of thermosol
Enhancing, so that thermosol is not easy the cracking that comes unglued during being patted, is conducive to extend thermosol
Service life, so that the flocking fastness of spun lacing nonwoven Flocked fabric improves.
By be added lotus leaf powder, be conducive to improve thermosol waterproof performance so that spun lacing nonwoven Flocked fabric into
When row dehydration, the water on spun lacing nonwoven Flocked fabric periphery is not easily penetrated into thermosol and corrodes thermosol or hydrolysis silicon
Alcohol reacts the ester generated with ethylene-acrylic acid copolymer, so that thermosol is not easy the cracking that comes unglued during the dehydration process, into
