The curtain is a part of household articles, along with the improvement of the living standard of people year by year and the continuous change of consumption concept, the function of the curtain is gradually developed from the initial decoration and privacy protection, the curtain is more and more accepted by people, and the specific function of the curtain is realized through the improvement of the weaving process and the material. The heat insulation function can effectively save energy, reduce outdoor high-temperature radiation to the indoor in summer, and increase indoor comfort.

At present, various window decoration fabrics produced at home and abroad mainly depend on coatings of external fabrics of curtains to achieve a certain heat insulation effect, and have the problems of poor heat insulation performance and short heat insulation effective period. During actual processing, the whole woven curtain is subjected to functional treatment to obtain a heat-insulating curtain, the curtain needs to be cleaned to obtain the curtain which has good compatibility with a heat-insulating coating, the color fastness of the heat-insulating coating is improved, and then the curtain is dried; the cleaned and dried curtain is coated with heat-insulating coating, and dip coating, roll coating and the like are usually needed, so that the coating can reach a certain thickness on the curtain: dewatering, extruding or spin-drying the wet film by the coated curtain, and extruding by a rubber roller; the extruded or spun-dried curtain is dried, and the drying and cleaning are repeated for a plurality of times to remove the redundant coating which is not completely attached to the material. The process for treating the whole curtain fabric to achieve the heat insulation effect is complex, the treatment capacity is large, water resource waste is caused by multiple times of cleaning, the environment is polluted, harmful gas is easy to volatilize in the using process, and certain harm is caused to the human health.

Disclosure of Invention

The invention provides a heat insulation curtain, which is characterized in that heat insulation yarns are woven into the curtain through a warp knitting process, and the curtain obtained through the warp knitting process directly has an excellent heat insulation effect and does not need subsequent treatment; on the other hand, the yarns with the heat insulation function have a high price compared with the common yarns, so that the heat insulation yarns achieve a good heat insulation effect under the condition of the minimum using amount by designing a proper warp knitting process, the production cost of the heat insulation curtain is reduced, the cost performance of the curtain is improved, and the heat insulation curtain has very important significance for popularization and application of the heat insulation curtain.

The invention realizes the purpose through the following technical scheme:

a heat insulation curtain is formed by weaving at least a chain knitting line, a lining weft and a heat insulation line, wherein the chain knitting line is woven in the warp direction of the curtain to form a chain knitting of the curtain, and two adjacent chain knitting are not intersected with each other; the weft insertion threads are woven in the weft direction of the curtain, two adjacent chain weaving threads are fixedly connected with the weft insertion threads after being looped to form weft insertion and padding yarns of the curtain, and the front surface and the back surface of the curtain are respectively provided with the weft insertion and padding yarns; the heat insulation line is arranged between two adjacent chain lines and is clamped between the weft insertion yarns on the front side and the back side of the curtain.

The heat insulation lines are fixed by weft threads arranged on the front and back surfaces of the curtain, so the heat insulation lines can be clamped between weft insertion backing yarns on the front and back surfaces of the curtain, or the heat insulation lines can be clamped between lifting threads on the front and back surfaces of the curtain, or one surface of the heat insulation lines is a weft insertion backing yarn, and the other surface of the heat insulation lines is a lifting thread. The heat insulation lines can be fixed by arranging weft yarns on the front surface and the back surface of the curtain.

Further, the heat insulation line is not fixedly connected with the chain knitting lines and the weft insertion lines, and the heat insulation line can be independently drawn out of the curtain. Because the heat insulating thread, the chain knitting thread and the weft insertion thread are not looped, the usage amount of the yarn can be reduced.

Preferably, the heat insulating line is a vertical line, the warp direction is arranged between two adjacent chain lines, and the weft direction is clamped between the weft insertion yarns on the front surface and the back surface.

Preferably, the heat insulation line is a curve and moves between two adjacent zipper lines, and the weft-wise heat insulation line is clamped between the weft-wise inlay yarns on the front surface and the back surface.

Preferably, a heat insulation line is arranged between any two adjacent chaining lines.

Alternatively, the heat insulating lines are arranged at intervals between the zipper lines.

The heat insulation wire is treated by a finishing agent on a warping machine, and the preparation method of the nano titanium dioxide finishing agent comprises the following steps: adding 0.5-1.0% of dodecylbenzene sulfonic acid, 0.1-0.5% of graphene oxide, 1.0-2.0% of nano titanium dioxide powder and 2.0-3.0% of resistant starch into deionized water by mass percent, uniformly stirring, and dispersing for 10-20 min by using ultrasonic.

The principle of the heat insulation curtain is mainly that the intensity is reduced by absorbing redundant sunlight, and the heat insulation is realized by reflecting most sunlight. The nano titanium dioxide is white loose powder, has strong ultraviolet shielding effect and good dispersibility and weather resistance. The yarn treated by titanium dioxide can effectively insulate heat. The effect of titanium dioxide load capacity in the yarn to thermal-insulated performance is very important, and the load capacity is few, and thermal-insulated effect is not obvious, and the firmness of titanium dioxide load in the yarn influences thermal-insulated effective time, and the firmness is low, and along with the extension of live time, the thermal-insulated effect of (window) curtain reduces gradually. Therefore, it would be valuable to develop a yarn with a high loading of titanium dioxide and high tenacity. The titanium dioxide is loaded into the yarn, which can be chemical fiber spinning or nanometer titanium dioxide is added in the spinning process, but the mode easily causes uneven dispersion of nanometer particles, is easy to block a nozzle, and simultaneously the mechanical property of the yarn is reduced. The nanometer titanium dioxide can be loaded on the surface of the yarn through a post-finishing mode, and the key point of the mode is that the nanometer titanium dioxide particles need to be uniformly dispersed in the finishing agent and have good bonding fastness with the fabric. According to the finishing agent, the graphene oxide, the dodecylbenzene sulfonic acid and the resistant starch are added into the finishing agent, so that the problems that nano titanium dioxide particles are easy to agglomerate, difficult to disperse and poor in binding fastness with a yarn substrate are solved. The finishing agent has the advantages of high dispersibility and good stability.

The graphene oxide has strong hydrophilicity and excellent dispersibility in water, and can provide a large specific surface area to effectively disperse the nano titanium dioxide and prevent agglomeration. And the graphene oxide has a plurality of oxygen-containing functional groups, such as hydroxyl (-OH), carboxyl (-COOH), carbonyl (C-O), epoxide and the like, and the oxygen-containing groups enable the graphene oxide to have strong plasticity, so that the adsorption force of the nano titanium dioxide in the yarn can be enhanced through the combination with resistant starch.

Furthermore, the looping guide bar is knitted into a hexagonal mesh tissue, and the flat guide bar places the heat insulation wire in a warp direction according to the movement track of the looping guide bar to form a hexagonal mesh shape.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

example 1

A heat insulation curtain is woven by chain knitting threads, weft interlining threads and heat insulation threads, and figure 1 is a yarn laying digital diagram of linear chain knitting threads: 0-1/1-0//, where the chain is a wale formed by laying a yarn in a loop on the same needle at all times, there is no crossover between the wales in the chain. Fig. 1 shows an open-ended pillar, with a heat insulating wire inserted between two adjacent pillars. The open-end chain can also be set to be a closed-end chain, and the padding number of the closed-end chain is 0-1//. Similarly, a heat insulation wire is directly inserted between two adjacent closed braids.

The braids can also be arranged in a hexagonal curve, as shown in fig. 2, the lapping number is 0-1/1-0/0-1/1-2/1-2/2-1/1-0//, and a heat insulation line is arranged between two adjacent braids, in this case, the heat insulation line is in a curve, and a hexagonal shape is formed between the adjacent heat insulation lines. The hexagonal heat insulation lines do not intersect with the braids, and the heat insulation lines can be extracted from the curtain from the longitudinal direction. Similarly, the braid may be provided in any other curved line, and the heat insulating line may be provided between two adjacent braid wires without crossing. The heat insulation line arranged in a curve has the advantages that the using amount of the line is increased compared with that of the straight-line arrangement, and the heat insulation effect is correspondingly improved.

The degree of density of the heat insulation lines can be adjusted according to the application, and when the heat insulation lines are arranged between two adjacent braids, the consumption of the heat insulation lines is maximum, and the covered surface area is also maximum. For example, the heat insulating lines may be provided at intervals in a plurality of columns formed by adjacent chains, the heat insulating lines may be provided in a first column, the heat insulating lines may not be provided in a second column, and the heat insulating lines may be provided in a third column, which are sequentially provided at intervals. Also, in the columns, the presence and absence of the heat-insulating lines may be in any combination.

The lining weft is arranged in the weft direction and is fixedly connected with the chain knitting line after being looped to form the lining weft and the padding yarn of the curtain. The running needles of the interlining yarns can be combined randomly, only the fact that the front side and the back side are provided with the interlining yarns is required, and generally, the interlining yarns with higher density can firmly clamp the heat insulation wires in the middle.

Tests show that in summer, the heat radiated by sunlight to the indoor is mostly reflected by using the heat insulation curtain, and the sun protection index can reach 60.8%. The indoor temperature is 7-15 degrees lower than that of a non-curtain and is 5-7 degrees lower than that of a common curtain. In winter, the heat insulation curtain is used, most of heat radiated to the curtain from indoor human bodies and objects can be reflected by the curtain, so that the heat is effectively prevented from being dissipated, and the room temperature is improved.
