Abstract

PURPOSE:To provide the subject voluminous spun yarn giving natural color tone, to be used as a raw material suitable for casual wears, having each specified twist and thickness, consisting of specific cotton fiber. CONSTITUTION:For example, cotton fiber 15-26mm in average length and >=5.0mug/min in micronaire fineness is passed, with its natural color retained, through a mixing and blowing process, a card, a comber and a drawframe followed by an air spinning frame, thus obtaining the objective spun yarn 3.5-6.0 in twist factor (inch system) and 5-40's (pref. 5-30's) in fineness in terms of Bradford count.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a special spun yarn suitable for outer casual wear.

(Prior Art) Spun yarns using thick fibers have traditionally been used for casual wear, and in order to create a casual effect, spun yarns that have not been bleached or dyed have been used.

However, conventional techniques simply omit dyeing or use thicker fibers, resulting in a lack of volume and fullness, as well as a lack of natural color, which is still inadequate for casual wear. Met.

(Problems to be Solved by the Invention) The present invention aims to provide a special spun yarn that has a natural, warm color and is suitable for casual wear with a sense of volume and fullness. .

(Means for Solving the Problem) The present invention takes the following means to solve the problem. That is, in the present invention, the average fiber length is 15 to 2.
8 sessions, micronaya fineness 5.0μg/in. Made of cotton fibers with a twist coefficient (inch system) of 3.5 to 6.0.
It is a special spun yarn characterized by having a thickness of English cotton count 5 to 40'S. The present invention will be explained in detail below. In the present invention, the average fiber length of the cotton fibers is 15 to 28
It's relevant. Average fiber length is 15. ．． If it is less than this, the yarn strength will be low and the weavability will be deteriorated, which is not preferable. On the other hand, 2 8
If it exceeds mm, the fluff will be iooo/
km or less, which is not desirable because it becomes difficult to create a sense of volume suitable for casual wear. Next, the thickness of the cotton fiber is Microneyar fineness of 5.0 μg.
/i n. If it is less than this, the sense of volume will decrease, which is not preferable. Furthermore, the twist coefficient (inch system) is 3.5 to 8.0.
Preferably it is 4.0 to 5.0. When the twist coefficient is less than 3.5, the yarn strength decreases because the staple fibers are short.
On the other hand, if it exceeds 6.0, the voluminous feel will decrease when it is made into a textile, which is not preferable. Here, the twist coefficient (inch system)
is the English cotton count Ne, and T is the English cotton count 5 to 40'S, preferably 5 to 30'S. If it is less than 5'S, it will give a sense of volume and fullness, but will not be suitable as a spun yarn for use in casual wear.On the other hand, if it exceeds 40'S, it will lack a sense of volume and fullness, which is not preferred. Note that the micronaya fineness is 5.0 μg/in. The cotton fibers are 1
Of course, it is possible for the spun yarn to consist of 00%, but
It may be blended with other cotton fibers having an average fiber length of 30 to 40 m. However, the mixing ratio of the latter is preferably 50% by weight or less.

Furthermore, the micronaya fineness used in the present invention is 5.0.
μg/in. The above-mentioned cotton fibers cannot be subjected to any post-processing even after being spun into yarn in order to produce a textured effect.

Here, the method for producing the special spun yarn of the present invention will be explained.

First, the average fiber length is 15 to 26 mm, and the micronaya fineness is 5.
．． 0 μg/i n. The above cotton fibers are fed in their natural color to a mixing and batting process, then passed through cards, combs, and draws, or passed through cards and draws, and then preferably fed to a so-called air spinning machine for spinning.

By using the spun yarn obtained in this way and making it into a knitted fabric and making it into casual wear without bleaching or dyeing, it is possible to obtain something rich in natural color and with a sense of volume and fullness.

(Example) Example 1 Micronaya fineness 6. Oμg/i n. Average fiber length 2
Spun yarn using 100% cotton fiber of 1.8 mm (Example 1)
, Micronaya fineness 6. Oμg/in. Average fiber length 2
70% by weight of cotton fibers of 1.8-+= and average fiber length of 34-
m, micronaya fineness 3.9μg/in. Spun yarn made by blending 30% by weight of cotton fibers in the cotton blending process (
Example 2), average fiber length 34, micronaya fineness 3
．． Spun yarns (conventional example 1) using 100% cotton fibers of 9 μg/In were manufactured under the conditions shown in Table 1, and the physical properties of the yarns and fabrics were evaluated (Tables 2 and 3).

O: Very present, O: Present, Δ: Slightly present, ×: Poor As is clear from the data in the table, Examples 1 and 2 were suitable for natural-toned casual wear. On the other hand, Conventional Example 1 had a whitish color and was unsatisfactory for casual wear.

(Effects of the invention) The special spun yarn of the present invention has a natural-toned appearance and is rich in volume and fluffy. Fabrics woven using this yarn can be manufactured without bleaching or dyeing. This has the remarkable effect of making it a material suitable for casual wear that takes advantage of its natural color tone.
