Description

Breathable durable flame-retardant jacquard fabric

Technical Field

The invention relates to the field of labor protection, in particular to a breathable durable flame-retardant jacquard fabric.

Background

Along with the popularization of flame-retardant tools, more and more users tend to use flame-retardant fabrics made of materials, and the post-treatment flame-retardant fabrics containing formaldehyde and having peculiar smell are avoided. The development of the technology of the flame-retardant fiber materials provides more alternative technical solutions for the flame-retardant fabric materials.

The flame-retardant fiber material suitable for the flame-retardant fabric comprises aramid fiber, polyimide, flame-retardant vinylon, polyarylate, flame-retardant acrylic fiber, flame-retardant viscose, polysulfonamide, polyester fiber and the like. Aramid fiber, polyimide, flame-retardant vinylon, polyarylate, polysulfonamide, polyester fiber and the like can be independently spun to prepare 100% flame-retardant fabric with independent components, but the product has high cost and poor comfort.

Although the flame-retardant acrylic fibers and the flame-retardant viscose can be independently spun to be made into 100% flame-retardant fabric with independent components, the comfort is relatively good, but the tear strength is poor, the wear resistance is poor, and the use value is low. The advantages and the disadvantages of the two types of fibers are organically combined to become an important research direction for developing flame-retardant fabrics.

At present, the mainstream technical scheme is as follows:

(1) CN200580007194 discloses an arc and flame resistant modacrylic/cotton/aramid fiber blend, (a)40 to 75 weight percent modacrylic fiber, (b)10 to 40 weight percent cotton fiber and; (c)1 to 40% by weight of aramid fibers, the percentages being based on the sum of components (a), (b) and (c).

(2) CN201310325303 discloses a yarn with multifunctional protective effect and fabric and garment made therefrom, a) diamino diphenyl sulfone fiber 40-60%; b) 20-30% of non-flame-retardant antibacterial cellulose fiber; c) 10-20% of modified polyacrylonitrile fiber; d) 5-10% of para-aramid fiber; e) 1-5% of antistatic fiber.

(3) JP2012074382 discloses a flame-retardant spun yarn, a fabric, clothes and flame-retardant work clothes, which adopt mixed fibers of polyarylate fibers and antimony-containing flame-retardant acrylic fibers, wherein the content of polyarylate is 1-30%.

(4) CN201410486633 discloses a flame-retardant fabric and a protective garment comprising the same, which comprises acrylic fiber, cotton fiber, flame-retardant rayon fiber containing a phosphorus flame retardant and para-aramid fiber, wherein the content of the acrylic fiber is 35 to 50 wt%, the total content of the cotton fiber and the flame-retardant rayon fiber containing a phosphorus flame retardant is 45 to 60 wt%, the content of the para-aramid fiber is 5 to 15 wt%, the acrylic fiber contains antimony oxide in an amount of 6.8 wt% or more relative to the total weight of the fibers, and the weight ratio of the flame-retardant rayon fiber to the cotton fiber is 1.0 to 1.95.

(5) CN201610460062 discloses a yarn/fabric/garment providing flame retardancy comprising three fibers in the following mass ratios, percentages being based on the sum of the mass of the three fibers: modified polyacrylonitrile: 20 to 80 percent; cellulose: 10% -50%; polyimide (I): 1 to 50 percent.

(6) WO2016JP65573 discloses a flame retardant fabric and protective clothing using the same, the present invention relates to a flame retardant fabric comprising para-aramid fiber, acrylic fiber, flame retardant rayon containing a phosphorus flame retardant and Lyocell fiber, the fabric comprising 5 to 15% by weight of para-aramid fiber, 50.5 to 65% by weight of acrylic fiber, and 15.5 to 44.5% by weight in total of Lyocell fiber and flame retardant rayon fiber containing a phosphorus flame retardant, the amount of the flame retardant rayon fiber containing a phosphorus flame retardant in the flame retardant fabric being 10.5% by weight or more relative to the total weight of the flame retardant fabric, and the content of the acrylic fiber containing an antimony compound being 3.9 to 20% relative to the total weight of the acrylic fiber. Namely, 5-15% of para-aramid, 50.5-65% of flame-retardant acrylic, 15.5-44.5% of lyocell fiber and flame-retardant viscose, wherein the flame-retardant viscose accounts for 10.5% or more.

The technical scheme disclosed above mainly uses aramid fiber, polysulfonamide, polyarylate, polyimide, flame-retardant acrylic fiber, and cellulose fiber (cotton, flame-retardant viscose, etc.). The core of the flame-retardant acrylic fiber and cellulose are used as main bodies, the scheme 1 is at least 60%, the scheme 3 is at least 70%, the scheme 4 is at least 85%, the scheme 5 is at least 50%, and the scheme 6 is at least 66%, in short, the flame-retardant acrylic fiber and cellulose mixture exceeding 50% endows the flame-retardant tooling with certain comfort.

The flame retardant acrylic fiber and cellulose fiber have poor abrasion resistance and durability. The customer partially emphasizes the actual use cost, not only sees the purchase cost of the flame-retardant tool, but also sees the average use cost of the flame-retardant tool in the use period, which is an important high-grade market in the flame-retardant tool, and hopes that the cost is relatively lower than that of pure aramid fiber, pure polysulfonamide, pure polyarylate and pure polyimide, and the flame-retardant tool has better comfort, certain hygroscopicity and better air permeability than that of pure aramid fiber, pure polysulfonamide, pure polyarylate, pure polyimide and pure flame-retardant vinylon, but the durability, namely the tearing strength and the wear resistance are not lower than or are highly close to those of the flame-retardant tools of pure aramid fiber, pure polysulfonamide, pure polyarylate and pure polyimide. The durability of the scheme 2 is relatively high, but after 45-70% of high modulus fibers are blended and then directly contact with the skin, the skin can itch, and the comfort is greatly reduced.

Therefore, it is difficult to obtain a technical solution with good compatibility by merely adjusting the blending ratio, so as to coordinate the relationship among flame retardancy, comfort, durability and cost.

The fabrics of examples 1 to 14 and comparative examples 1 to 13 were subjected to flame retardancy, durability, comfort test and raw material cost comparison, respectively, and the results are as follows.

Flame retardancy test results:

carrying out a vertical burning test according to GB/T5455, wherein the continuous burning time of the examples 1-14 and the comparative examples 1-13 is less than 1.5 seconds, and the requirement of ≦ 2 seconds is met; the damage length of the composite material is less than 100mm in examples 1 to 14 and comparative examples 1 to 12, and the requirement of less than or equal to 100mm is met, but the damage length of the composite material is 167mm, and the requirement of less than or equal to 100mm is not met. In example 5, yarns which are unfavorable for damage length and are like the yarns in the comparative example 13 are introduced, and the damage length of the whole finished fabric is not more than 100mm when the yarns are woven into the group B, so that the fabric in example 5 is more reasonable in structure, and the whole fiber proportioning design is more scientific.

Aiming at the durability, the Martindale wear resistance and the fabric tearing strength are respectively tested. The wear resistance is the wear resistance of the A group of the fabric.

TABLE 1

The tear property and abrasion resistance were the best in comparative examples 7 to 12. In the embodiments 1 to 14, the durability of the corresponding fibers in the comparative examples 7 to 12 is well inherited, and although the overall fiber composition is greatly different, the wear resistance of the A group surface of the fabric is not greatly reduced, and the A group surface of the fabric meets the high requirements of customers. As can be seen from the above table, in the disclosed solutions 1 to 6 represented by the comparative examples 1 to 6, except for the solution 2, none of the solutions can meet the requirements of both the tear strength and the abrasion resistance test. The fiber blend of comparative example 13 was the yarn of group B of example 5, which, if used alone, had the worst tear strength and abrasion resistance and completely failed to meet the customer's requirements. Example 5 performed well as a whole, reflecting the science of the organic combination of fiber components and structure of example 5. The tearing strength of the yarns in the groups B is not reduced because the yarns in the groups B are similar to the yarns in the comparative example 13, and the tearing strength is not reduced because the fabric is of a relatively three-dimensional double-group structure, so that the fabric is soft and is favorable for tearing.

The comfort test results are shown in table 2:

TABLE 2

Examples 1 to 14 all met the customer requirements for moisture permeability and air permeability, and none of the comparative examples except comparative example 13 could meet the customer requirements for moisture permeability and air permeability at the same time. The group A and the comparative example 7 of the example 1 are 100% of meta-aramid, the moisture permeability of the example is 11.24% higher than that of the comparative example 7, the air permeability is 54.2% higher, and the effect of the fabric structure is very obvious.

As the B groups of the embodiments 1 to 14 all contain the mixture of the soft water-absorbing cellulose fiber and the flame-retardant acrylic fiber, the skin-friendly performance of the fabric is good, and as the moisture and air permeability data of the test in the table above, the moisture and air permeability of the fabric of the embodiments 1 to 14 can be seen, and the comfort is much better than that of the fabrics of the comparative examples 1 to 12.

And (3) raw material cost measurement:

based on 100% of natural color meta-aramid, the price of the dope-dyed meta-aramid is approximately 205%, the natural color of the para-aramid is 180%, the aromatic polysulphone is 105%, the polyarylate is 500%, the polyimide is 200%, the flame-retardant acrylic is 60%, the cotton is 25%, the lyocell is 25%, the pre-oxidized fiber is 150%, the carbon fiber is 250%, the polyester is 10%, and the nylon is 30%. Because the yarns in the B group adopt the mixture mainly containing the flame-retardant acrylic fibers and the cellulose, the cost advantage is very obvious, and particularly when the mass of the B group is close to that of the A group, namely the mass ratio is close to 50: 50, more so.

In conclusion, for customers with relatively low cost, good durability and good comfort, comparative examples 1 to 6 corresponding to the disclosed schemes 1 to 6 cannot simultaneously meet the requirements of comfort and durability; for the fabric made of pure strong fibers, the requirements of comfort and relatively low cost cannot be met; the fabric of comparative example 13 had the lowest cost and good comfort, but the flame retardancy did not meet the requirements. The results of the embodiments 1 to 14 prove that the technical scheme of the invention is very effective and can meet the requirements of customers on flame retardance, durability, comfort and low cost.

In addition, the comparative example 14 and the comparative example 15 are also exemplified for the effect of the joint structure of the group A and the group B on the performance of the facing material. Comparative example 14 corresponds to example 4 and comparative example 15 corresponds to example 13.

The yarn composition, count and weaving structure of the groups A and B of the comparative example 14 are all 1/1 plain yarns, the warp and weft density is completely the same as that of the example 4 (the group A is 2 times of the warp and weft density of the group B), the processing technology is also the same, but the connection mode of the group A and the group B is slightly different, the group B warp yarn of the example 4 is interwoven with the group A weft yarn every 7, the group B weft yarn is interwoven with the group A warp yarn every 6, the group A and the group B are both 1/1 plain yarns, the warp and weft density of the group A is twice of that of the group B, and the number of the interweaving points of the group A in unit area is 4 times of that of the group B. The interleaving point of the a group is 8 × 2 × 7 × 2 ═ 224, and the connection point is 1/224 of the interleaving point of the a group. The group B warp yarns of comparative example 14 interweave with the group a weft yarns every 7, the group B weft yarns interweave with the group a warp yarns every 7, both group a and group B are 1/1 plain yarns, the warp and weft yarn density of group a is twice that of group B, the number of interweaving points per unit area of group a should be 4 times that of group B, the interweaving points of group a is 8 × 2 × 8 × 2 ═ 256, and the connecting point is 1/256 of the interweaving points of group a. The indexes of flame retardance, tearing and comfort of the comparative example 14 are basically the same as those of the example 4 and meet the requirements, but the abrasion resistance of the comparative example 14 is only 38747 turns and cannot meet the requirement of 40000, the weft yarns of the B group are found to be easy to fall off in the cutting process, and the practicability of the fabric is reduced. The reason why the wear resistance is not qualified is mainly because the connecting points are too few, the group A and the group B are separated, the weft yarn of the group B is easy to fall off, and the yarn is easy to be drawn during testing.

In comparative example 15, the yarn composition, count, weave structure (2/1 twill for group a and 3/1 twill for group B), warp and weft density were the same as in example 13 (warp and weft density for group a and group B), and the processing technique was the same, but the connection manner between group a and group B was slightly different. Group B warp yarns of example 13 interweave with group a weft yarns every 6 and group B weft yarns interweave with group a warp yarns every 3. The warp and weft densities of the group A and the group B are consistent, the group A is 2/1 twill, and the interlacing points of the group A are more than those of the group B3/1 twill. The interleaving point of the a group is 7 × 4/3 ═ 9. The connection points are 1/9 for the a set of interlace points. Group B warp yarns of comparative example 15 interweave with group a weft yarns every 5 and group B weft yarns interweave with group a warp yarns every 3. The warp and weft densities of the group A and the group B are consistent, the group A is 2/1 twill, and the interlacing points of the group A are more than those of the group B3/1 twill. The interleaving point of the a group is 6 × 4/3 ═ 8. The connection points are 1/8 for the a set of interlace points. Comparative example 15 has substantially the same indices of flame retardancy, tear resistance, abrasion resistance and moisture permeability as example 13, and meets the requirements, but has an index of air permeability of 54mm/s or less than 60 mm/s. It is not satisfactory. The reason for failure is too many connecting points and the void effect is not obvious.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
