A kind of autumn and winter composite materialTechnical field
The present invention relates to a kind of autumn and winter composite materials.
Background technique
It defends clothing and defends trousers, be common autumn and winter clothing, it is very popular with its comfortable warm feature.
The Chinese patent that Authorization Notice No. is CN203246129U, Authorization Notice No. day is on October 23rd, 2013 disclosesA kind of raising it is warming defend clothing fabric comprising the outer layer made of elastic composite fiber, the middle layer made of sponge and byInternal layer made of naked spandex yarn has teasing layer on internal layer.
Internal layer and teasing layer and skin or the fitting of internal clothing, when wearing off clothing due to rubbing action, on internal layerIt teasing layer a possibility that there are hair loss, causes to be stained with considerable amount of fiber on skin or internal clothing.
Summary of the invention
The object of the present invention is to provide a kind of autumn and winter composite material, the problem of which solve hair loss, has and reduceThe advantages of hair possibility.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of autumn and winter composite material, including hot coarctate flannelette napped fabric layer, bonding glue-line and cotton layer from inside to outside,It is prepared by the following method:
(1) cotton is taken, is formed at 185~195 DEG C, preshrunk is handled at 115~125 DEG C, obtains cotton layer；
(2) flannelette is taken, is formed at 167~172 DEG C, preshrunk is handled at 115~125 DEG C, obtains flannelette napped fabric layer；
(3) cotton layer for taking step (1) to obtain applies in the inside of cotton layer and spreads adhesive glue；The suede for taking step (2) to obtainLayer of cloth applies in the inside of flannelette napped fabric layer and spreads adhesive glue；Bonding is coated with by being coated on the side and flannelette napped fabric layer of adhesive glue on cotton layerThe side of glue is bonded, and then hot pressing is compound at 148~153 DEG C, washing to get；
Wherein, flannelette using polar fleece or not fall suede；
The grammes per square metre of the flannelette napped fabric layer is 160~175g/m2；
The grammes per square metre of the bonding glue-line is 4~10g/m2；
The grammes per square metre of the cotton layer is 135~145g/m2。
By adopting the above technical scheme, firstly, by polar fleece or falling suede and cotton compound, the polar fleece that passes through adhesive glue hot pressingOr suede is not fallen as internal layer, so that a kind of autumn and winter of the application is not easy hair loss with composite material in the process of wearing；Secondly, shakingGrain suede or do not fall suede fluffy degree it is high, and the density of cotton is big, more consolidation, the two by adhesive glue hot pressing it is compound after so thatA kind of warmth retention property of autumn and winter composite material of the application is good；In addition, selecting cotton, polar fleece or the suede that do not fall more softIt is soft, and strict control setting temperature and the compound temperature of hot pressing, reduce hot pressing combined temp it is excessively high caused by fabric hardening feelingsThe case where combining loosely caused by condition or temperature are too low relaxes so that a kind of autumn and winter of the application is more soft with composite materialIt is suitable, it is suitable for various people；It is worth noting that, when the first each self-fixing preshrunk processing hot repressing of cotton and flannelette is compound and mistakeEach temperature control in journey, the washing shrinkage and inside and outside shrinking percentage of a kind of autumn and winter composite material that can greatly reduceThe excessive situation of difference maintains web surface smooth；In addition the study found that when using polar fleece as internal layer, dress is well-pressed, moreTo there is type.
Further preferably are as follows: the cotton layer uses pure cotton single jersey.
By adopting the above technical scheme, pure cotton single jersey refers to that ingredient is the facecloth of 100% cotton, with preferable moisture absorptionProperty, it is comfortable and easy to wear；Secondly it is close orderly, can enhance warmth retention property, comfortable antiallergy；And it is in the sizing preshrunk method of the applicationIt can be consistent substantially after being handled with the shrinkage of flannelette, reduce the excessive situation of inside and outside shrinking percentage difference.
Further preferably are as follows: in step (1), the setting temperature of cotton is 185~190 DEG C, preshrunk treatment temperature is 120~125℃。
In step (2), the setting temperature of flannelette is 167~170 DEG C, and preshrunk treatment temperature is 120~125 DEG C.
In step (3), the compound temperature of hot pressing is 148~150 DEG C.
The grammes per square metre of the flannelette napped fabric layer is 160~170g/m2。
The grammes per square metre of the bonding glue-line is 5~10g/m2。
The grammes per square metre of the cotton layer is 135~140g/m2。
By adopting the above technical scheme, it reduces bulge, smear the detailed problem occurred in the techniques such as irregular.
Further preferably are as follows: adhesive glue used in the bonding glue-line includes following component:
PEO-PPO-PEO triblock copolymer: 2~5wt%；
Polyurethane: 1~3wt%；
High density polyethylene (HDPE): 1~2wt%；
Functional aid: 1~3wt%；
Surplus is solvent；
Wherein, the functional aid is selected from one of dispersing agent, stabilizer, lubricant, defoaming agent or a variety of；It is describedSolvent includes the water of 0~20wt% and the organic solvent of 80~100wt%, and the organic solvent is selected from C1~C3In alcohol, acetoneIt is one or more.
By adopting the above technical scheme, PEO-PPO-PEO triblock copolymer and internal layer, outer layer can combine, enhancingAdhesiveness, while adhesiveness can be reinforced by polyurethane, high density polyethylene (HDPE) and improve the problem of adhesive glue hardens.
In conclusion the invention has the following advantages:
1, it is not easy hair loss；
2, warmth retention property is good；
3, soft, comfortably, it is suitable for easy allergic human population；
4, binding strength is strong；
5, washing shrinkage is low, and inside and outside shrinking percentage difference is small, smooth；
6, when using polar fleece as internal layer, dress is well-pressed, more there is type.
