Description
Technical Field
The application belongs to the technical field of fabrics, and particularly relates to a fabric.
Background
At present, only knitted underwear has the industry standard of FZ/T73036 and 2010 moisture absorption and heating knitted underwear; the field of clothes such as woven fabrics and the like also lacks of industrial standards related to moisture absorption and heat generation. It is said that in the field of woven fabric and the like, materials which absorb moisture and generate heat are rarely used.
The method for measuring the moisture absorption and heat generation functions of the fabric is measured according to the national standard GB/T29866-2013. The moisture absorption and heat generation temperature rise value index is that the maximum temperature rise value is more than or equal to 4 ℃, and the average temperature rise value within 30min is more than or equal to 3 ℃. Wherein, the two indexes of the maximum temperature rise value and the average temperature rise value within 30min must meet the requirements at the same time to be qualified, and the two indexes are not qualified.
The technical standard reading of the moisture absorption and heating knitted underwear records that: in the process of preparing the standard, the national knitted product quality supervision and inspection center tests nearly hundreds of fabrics. Test results show that 40% of the fabrics in nearly hundred pieces of tested fabrics can meet the requirements of the two indexes, and the indexes are finally determined to be that the maximum heating value is more than or equal to 4 ℃ and the average heating value is more than or equal to 3 ℃ within 30min through repeated analysis and study with experts in the industry. From the content of the document, it is known that two indexes of nearly hundreds of test knitted fabrics simultaneously reach the required 40 percent, which means that the knitting is difficult to reach the requirement of the moisture absorption and heat generation index.
Compared with the knitted fabric, the woven fabric with the same gram weight has poor bulkiness and thickness; the heat retention is relatively poor. Therefore, the difficulty of meeting the requirement of the moisture absorption and heat generation index is more difficult for the woven fabric than the knitted fabric. The most obvious differences between weaving and knitting are: the machine weaving is formed by interweaving warp and weft, the interweaving place of the warp and weft is bent, the extension and contraction relationship of the warp and weft is not large, and the conversion does not occur, so that the woven fabric is generally compact and hardAnd (6) lifting. The knitted fabric is formed by continuously looping one coil, the coil is formed by bending yarns in space, each coil is formed by one yarn, and the height and the width of each coil can be obviously converted mutually under different tension conditions, so that the knitted fabric has the advantages of high extensibility, fluffiness/softness, more air retained among the coils and warm feeling. If the woven fabric is to reach the moisture absorption and heat generation indexes, the gram weight of the fabric is at least 480g/m2However, the fabric has a disadvantage of being thick. Compared with the prior art, the woven fabric has the gram weight of 250-400g/m2And the target requirements of the national standard of moisture absorption and heat generation can be met very rarely.

In table 1 above, R35T 35 hygroscopic exothermic a30 indicates: 35% of viscose, 35% of terylene and 30% of hygroscopic heating acrylic fiber, wherein T68R 29 SP3 represents that: 68% of terylene, 29% of viscose and 3% of spandex, wherein T88R 11 SP1 represents that: 88% of terylene, 11% of viscose and 1% of spandex, wherein T100 represents: 100 percent of terylene. Wherein, the setting proportion of the hygroscopic exothermic acrylon in the embodiment 1 is not less than 25%.
As can be seen from table 1, the hygroscopic and exothermic acrylon with the setting proportion of 30% is adopted in the above example 1, and compared with the control group 1, the control group 2 and the control group 3, the example 1 can satisfy the hygroscopic and exothermic indexes specified in the national standard GB/T29866-: the maximum temperature rise value is more than or equal to 4 ℃, and the average temperature rise value within 30min is more than or equal to 3 ℃, thus being a qualified product.

The yarn is organically combined with the fabric design and dyeing and finishing processing, so that the optimal rationalization is realized, and the excellent moisture absorption and heat generation performance is obtained.

In table 2 above, R35T 35 hygroscopic exothermic a30 indicates: 35% of viscose, 35% of terylene and 30% of hygroscopic exothermic acrylon, R45T 40 hygroscopic exothermic A15 shows that: 45% of viscose, 40% of terylene and 15% of hygroscopic exothermic acrylon, R45T15 hygroscopic exothermic A40 shows that: 45% of viscose, 15% of terylene and 40% of hygroscopic and exothermic acrylon.
Moreover, as can be seen from table 2, the setting proportions of the viscose, the polyester and the hygroscopic and exothermic acrylon are different, and the obtained hygroscopic and exothermic properties of the fabric made of the viscose, the polyester and the hygroscopic and exothermic acrylon are also different, wherein the implementation 1 can meet the hygroscopic and exothermic indexes specified in the national standard GB/T29866-2013: the maximum temperature rise value is more than or equal to 4 ℃, and the average temperature rise value within 30min is more than or equal to 3 ℃, thus being a qualified product. The setting proportion of the moisture absorption and heat generation acrylic fibers in the embodiment 2 is less than 15 percent and less than 25 percent, the maximum heating value can not be simultaneously satisfied to be more than or equal to 4 ℃, and the average heating value within 30min is more than or equal to 3 ℃, and the product is unqualified; in example 3, although the setting ratio of the moisture absorption and heat generation acrylic fibers is 40% or more and 25%, the maximum temperature rise value is not less than 4 ℃ and the average temperature rise value is not less than 3 ℃ within 30min, which is not qualified.
Therefore, in specific application, in order to meet the moisture absorption and heat generation index specified in the national standard GB/T29866 and 2013, in addition to the setting ratio of the moisture absorption and heat generation acrylic fibers, the setting position of the moisture absorption and heat generation acrylic fibers needs to be considered, wherein in this embodiment, the inner warp or the inner weft adopts the moisture absorption and heat generation acrylic fibers.
The following comparative analysis of the hygroscopic heating properties of the fabric of this embodiment, which are generated by different positions of the hygroscopic heating fibers, is shown in table 3 below.
Table 3 comparative analysis table for hygroscopic heating properties generated at different arrangement positions of hygroscopic heating fibers
And as can be seen from the above table, when the inner warp or the inner weft adopts the hygroscopic heating fiber and the setting proportion of the hygroscopic heating fiber is more than or equal to 25%, the hygroscopic heating index specified by the national standard GB/T29866-2013 can be met, namely, the maximum rising temperature value is more than or equal to 4 ℃, and the average rising temperature value is more than or equal to 3 ℃ within 30min, so that the product is qualified; and when the binding weft adopts the moisture absorption heating fibers, the maximum heating value cannot be simultaneously satisfied to be more than or equal to 4 ℃, and the average heating value within 30min is more than or equal to 3 ℃, so that the binding weft is an unqualified product.
It is known in the industry that the density of warp yarns is generally higher than that of weft yarns in a woven fabric, if the warp yarns and the weft yarns adopt the same moisture-absorbing and heat-generating fibers, the moisture-absorbing and heat-generating fiber components of the warp surface are more than those of the weft surface, and the moisture-absorbing and heat-generating effect of the warp surface is better than that of the weft surface. By analogy with the above results and in combination with the above Table 3, it is understood that the heat-generating effect of example 4 using the hygroscopic exothermic acrylic is slightly better than that of example 5.
Compared with the existing knitted fabric, the woven fabric with the moisture absorption and heat generation functions has light weight (the gram weight is 250-400 g/m)2) Can achieve the heat preservation effect and has longer heat preservation time, and can meet the requirement of national standard GB/T29866 supple heat 2013 for the moisture absorption and heating functional measurement of the fabric, namely, simultaneously meets the highest heating valueThe average temperature rise value is more than or equal to 4 ℃ and more than or equal to 3 ℃ within 30 min. Therefore, the method has a wide market application prospect.
